IF ENGINE FAILS TO START
If the engine fails to start after you have followed the
“Normal Starting” procedure and the vehicle has not
experienced an Extended Park condition as defined
above, it may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while the engine is
cranking. This should clear any excess fuel in case the
engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release
the accelerator pedal and the brake pedal, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the ignition
button/key is released. If this occurs, continue cranking
with the accelerator pedal pushed all the way to the floor.
Release the accelerator pedal and the ignition button/key
once the engine is running smoothly.
If the engine shows no sign of starting after a 10 second
period of engine cranking with the accelerator pedal held
to the floor, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED

Engine Block Heater Cord Location

The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the heater
cord to a ground-fault interrupter protected 110–115 Volt
AC electrical outlet with a grounded, three-wire extension
cord.
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater
(available from an authorized dealer) is recommended.
The engine block heater cord is routed under the hood on
the passenger side of the vehicle next to the engine
coolant reservoir.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
 Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans -
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
 If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type of
start can be dangerous if done improperly
Úpage 325.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
WARNING!
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.

STARTING AND OPERATING123
(Continued)
You may also notice a small amount of movement in the
brake pedal. Once the parking brake is fully disengaged,
the BRAKE telltale light in the instrument cluster and the
LED indicator on the switch will extinguish.
NOTE:When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away from
the curb on an uphill grade. Apply the parking brake before
placing the gear selector in PARK, otherwise the load on
the transmission locking mechanism may make it difficult
to move the gear selector out of PARK.
If exceptional circumstances should make it necessary to
engage the parking brake while the vehicle is in motion,
maintain upward pressure on the EPB switch for as long as
engagement is desired. The BRAKE telltale light will
illuminate, and a continuous chime will sound. The rear
stop lamps will also be illuminated automatically while the
vehicle remains in motion.To disengage the parking brake while the vehicle is in
motion, release the switch. If the vehicle is brought to a
complete stop using the parking brake, when the vehicle
reaches approximately 3 mph, (5 km/h) the parking brake
will remain engaged.
In the unlikely event of a malfunction of the EPB system, a
yellow EPB Warning Light will illuminate. This may be
accompanied by the BRAKE telltale light flashing. In this
event, urgent service of the EPB system is required. Do not
rely on the parking brake to hold the vehicle stationary.
Auto Park Brake
The Electric Park Brake (EPB) can be programmed to be
applied automatically whenever the vehicle is at a
standstill and the automatic transmission is placed in
PARK. Auto Park Brake is enabled and disabled by
customer selection through the Customer Programmable
Features section of the Uconnect Settings
Úpage 206.
Any single Auto Park Brake application can be bypassed by
pushing the EPB switch to the release position while the
transmission is placed in PARK.
WARNING!
 Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
 When exiting the vehicle, always remove the key fob
from the ignition and lock your vehicle.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
gear selector.
 Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter ‘n Go™ in the
ACC or ON/RUN position. A child could operate power
windows, other controls, or move the vehicle.
 Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
 Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an
authorized dealer immediately.
WARNING!
WARNING!
Driving the vehicle with the parking brake engaged, or
repeated use of the parking brake to slow the vehicle,
may cause serious damage to the brake system.
Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and a
collision.

STARTING AND OPERATING125
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF position. This helps the
driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system also locks
the transmission in PARK whenever the ignition is in the
OFF position.
NOTE:The transmission is NOT locked in PARK when the ignition
is in the ACC position (even though the engine will be off).
Ensure that the transmission is in PARK, and the ignition
is OFF (not in ACC position) before exiting the vehicle.
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI system that holds the
transmission gear selector in PARK unless the brakes are
applied. To shift the transmission out of PARK, the engine
must be running and the brake pedal must be pressed. The brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.
8-SPEED AUTOMATIC TRANSMISSION
Rotary Shifter — If Equipped
The transmission is controlled using a rotary electronic
gear selector located on the instrument panel. The
transmission gear range (PRND) is displayed both above
the gear selector and in the instrument cluster. To select
a gear range, simply rotate the gear selector. You must
press the brake pedal to shift the transmission out of
PARK (or NEUTRAL, when the vehicle is stopped or moving
at low speeds). To shift past multiple gear ranges at once
(such as PARK to DRIVE), simply rotate the gear selector
to the appropriate detent. Select the DRIVE range for
normal driving.
NOTE:In the event of a mismatch between the gear selector
position and the actual transmission gear (for example,
driver selects PARK while driving), the position indicator
will blink continuously until the selector is returned to the
proper position, or the requested shift can be completed.
The electronically controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).

Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF position, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
 When exiting the vehicle, always make sure the
ignition is in the OFF position, remove the key fob
from the vehicle, and lock the vehicle.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
transmission gear selector.
 Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do not
leave the ignition in the ACC or ON/RUN position.
A child could operate power windows, other controls,
or move the vehicle.
WARNING!CAUTION!
Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
 Do not shift between PARK, REVERSE, NEUTRAL, or
DRIVE when the engine is above idle speed.
 Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.

23_DT_OM_EN_USC_t.book Page 125

126STARTING AND OPERATING

Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE positions. Manual downshifts can be
made using the Electronic Range Select (ERS) shift control.
Pushing the GEAR “-”/GEAR “+” switches (on the steering
wheel) while in the DRIVE position will select the highest
available transmission gear, and will display that gear limit
in the instrument cluster as 1, 2, 3, etc.

Ú
page 128. Some
models will display both the selected gear limit, and the
actual current gear, while in ERS mode.
Electronic Transmission Gear Selector

Console Shifter — If Equipped

The transmission gear range is displayed both beside the
gear selector and in the instrument cluster. To select a gear
range, push the lock button on the gear selector and move
the selector rearward or forward. To shift the transmission
out of PARK (P), the engine must be running and the brake
pedal must be pressed. You must also press the brake pedal to shift from NEUTRAL
(N) into DRIVE (D) or REVERSE (R) when the vehicle is
stopped or moving at low speeds. Select the DRIVE range for
normal driving.

NOTE:

The transmission electronics are self-calibrating; there -
fore, the first few shifts on a new vehicle may be some -
what abrupt. This is a normal condition, and precision
shifts will develop within a few hundred miles
(kilometers).
 In the event of a mismatch between the gear selector
position and the actual transmission gear (for example,
driver selects PARK while driving), the position indi -
cator will blink continuously until the selector is
returned to the proper position, or the requested shift
can be completed.
The electronically controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions.
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector provides PARK, REVERSE,
NEUTRAL, and SPORT (S) (AutoStick) shift positions.
Manual shifts can be made using the AutoStick shift
control. Toggling the gear selector forward (-) or rearward
(+) while in the SPORT (AutoStick) position (beside the
DRIVE position), or tapping the paddle shifters (+/-) (if
equipped), will manually select the transmission gear, and
will display the current gear in the instrument cluster
Úpage 129.

Gear Selector

NOTE:
If the gear selector cannot be moved to the PARK,
REVERSE, or NEUTRAL position (when pushed forward), it
is probably in the AutoStick (+/-) position (beside the
DRIVE position). In AutoStick mode, the transmission gear
(1, 2, 3, etc.) is displayed in the instrument cluster. Move
the gear selector to the right (into the DRIVE position) for
access to PARK, REVERSE, and NEUTRAL.
Gear Ranges
Do not press the accelerator pedal when shifting from
PARK or NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to allow the
selected gear to engage before accelerating. This is espe -
cially important when the engine is cold.

23_DT_OM_EN_USC_t.book Page 126

STARTING AND OPERATING127
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when exiting the vehicle in this
range.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill grade.
NOTE:On four-wheel drive vehicles be sure that the transfer case
is in a drive position.
When exiting the vehicle, always:
Apply the parking brake.
 Shift the transmission into PARK.
 Turn the engine off.
 Remove the key fob from the vehicle. The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position:

Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
 With the brake pedal released, verify that the gear
selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must exit the
vehicle. DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong head
winds, or while towing a heavy trailer), select TOW/HAUL
mode or use the Electronic Range Select (ERS) shift
control to select a lower gear range
Úpage 128. Under
these conditions, using a lower gear range will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified
depending on engine and transmission temperature as
well as vehicle speed. Normal operation will resume once
the transmission temperature has risen to a suitable level.
CAUTION!
 DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range, as this can
damage the drivetrain.
 Before moving the transmission gear selector out of
PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
WARNING!
Do not coast in NEUTRAL and never turn off the ignition
to coast down a hill. These are unsafe practices that
limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.

AXLE LOCK SYSTEM — IF EQUIPPED
This vehicle is equipped with an electronically locking rear
differential. When engaged, this differential locks the axle
shafts forcing the wheels to spin at an equal rate. The
locking of the rear differential should only be engaged
during low-speed, extreme off-road situations where one
wheel is likely to not be in contact with the ground. It is not
recommended to drive the vehicle with the differentials
locked on pavement due to the reduced ability to turn and
speed limitations.

AXLE LOCK Button

The locking rear axle is controlled by the AXLE LOCK
button.
Under normal driving conditions, the rear axle should be
unlocked.
During the command to lock the rear axle, the indicator
light will flash until the axle is locked. After the lock
command has been successfully executed, the light will
remain on solid.
Operating in 4WD LOW the locker can be engaged up to
40 mph (64 km/h) and will remain engaged throughout
the 4WD LOW speed range.
Operating the locker in 2WD, 4WD AUTO, and 4WD
LOCK/HIGH, the locker can be engaged up to 20 mph
(32 km/h). While driving with the locker engaged, if speed
exceeds 25 mph (40 km/h), the locker will automatically disengage, but will automatically re-engage at 20 mph
(32 km/h).
NOTE:Left to right wheel speed difference may be necessary to
allow the rear axle to fully lock. If the indicator light is
flashing after selecting the rear axle lock mode, drive the
vehicle in a turn or on loose gravel to expedite the locking
action.
The axle locker could become torque locked due to side to
side loads on the rear axle. Driving slowly while turning the
steering wheel from a left hand turn to a right hand turn or
driving in REVERSE for a short distance may be required to
release the torque lock and unlock the axles.
To unlock the rear axle, push the AXLE LOCK button.
The AXLE LOCK indicator light will go out when the rear
axle is unlocked.
LIMITED-SLIP DIFFERENTIAL —
IF EQUIPPED
The limited-slip differential provides additional traction on
snow, ice, mud, sand and gravel, particularly when there is
a difference between the traction characteristics of the
surface under the right and left rear wheels. During
normal driving and cornering, the limited-slip unit
performs similarly to a conventional differential. On
slippery surfaces, however, the differential delivers more
of the driving effort to the rear wheel having the better
traction.
CAUTION!
 Do not lock the rear axle on hard surfaced roads. The
ability to steer the vehicle is reduced and damage to
the drivetrain may occur when the axle is locked on
hard surfaced roads.
 Do not try to lock the rear axle if the vehicle is stuck
and the tires are spinning. You can damage
drivetrain components. Lock the rear axle before
attempting situations or navigating terrain, which
could possibly cause the vehicle to become stuck.

23_DT_OM_EN_USC_t.book Page 140

STARTING AND OPERATING141
The limited-slip differential is especially helpful during
slippery driving conditions. With both rear wheels on a
slippery surface, a slight application of the accelerator will
supply maximum traction. When starting with only one
rear wheel on an excessively slippery surface, slight
momentary application of the parking brake may be
necessary to gain maximum traction.
Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could
cause both rear wheels to spin, and allow the vehicle to
slide sideways on the crowned surface of a road or in a
turn.
POWER STEERING
ELECTRIC POWER STEERING
The electric power steering system will provide increased
vehicle response and ease of maneuverability. The power
steering system adapts to different driving conditions.
If the steering icon is flashing, it indicates that the vehicle
needs to be taken to an authorized dealer for service. It is
likely the vehicle has lost power steering assistance. If the steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is displayed on
the instrument cluster screen, this indicates an over
temperature condition in the power steering system. Once
driving conditions are safe, pull over and let the vehicle
idle for a few moments until the icon and message turn off
Úpage 98.
If the steering icon is displayed and the “SERVICE POWER
STEERING – ASSIST OFF” message is displayed on the
instrument cluster screen, this indicates the vehicle needs
to be taken to an authorized dealer for service
Úpage 98.
NOTE:
 Even if the power steering assistance is no longer oper -
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 If the condition persists, see an authorized dealer for
service.
FUEL SAVER TECHNOLOGY 5.7L ENGINES
ONLY — IF EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine's eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE:This system may take some time to return to full function -
ality after a battery disconnect.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function, included with eTorque equipped
vehicles, is developed to save fuel and reduce emissions.
The system will stop the engine automatically as the
vehicle decelerates at low speeds if the required
conditions are met. Releasing the brake pedal or shifting
out of DRIVE will automatically restart the engine.
Vehicles equipped with eTorque contain a heavy-duty
motor generator and an additional hybrid electric battery
to store energy from vehicle deceleration used to expand
engine off energy storage and for engine startup after a
stop, as well as providing engine torque assist when
conditions are met to enable this.
AUTOSTOP MODE
The Stop/Start feature is enabled after every normal
customer engine start. It will remain in STOP/START NOT
READY until you drive forward with a vehicle speed greater
than 2 mph (3 km/h). At that time, the system will go into
STOP/START READY and if all other conditions are met,
the system may go into STOP/START AUTOSTOP ACTIVE
Autostop mode.
WARNING!
When servicing vehicles equipped with a limited-slip or
locking differential, never run the engine with one rear
wheel off the ground as the vehicle may drive through
the rear wheel remaining on the ground and result in
unintended movement.

(32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below 20 mph
(32 km/h).
If either system is set when the vehicle speed is above
20 mph (32 km/h), the set speed shall be the current speed of the vehicle.
NOTE:
 Keeping your foot on the accelerator pedal can cause
the vehicle to continue to accelerate beyond the set
speed. If this occurs, the message “ACC DRIVER
OVERRIDE” will display in the instrument cluster
display.
 If you continue to accelerate beyond the set speed
while ACC is enabled, the system will not control the
distance between your vehicle and the vehicle ahead.
The vehicle speed will only be determined by the posi -
tion of the accelerator pedal.
To Cancel
The following conditions cancel the ACC or Fixed Speed
Cruise Control systems:
 The brake pedal is applied
 The CANC (cancel) button is pushed
 The Anti-Lock Brake System (ABS) activates
 The trailer brake is applied manually (if equipped)
 The gear selector is removed from the DRIVE position

WARNING!
Leaving the Adaptive Cruise Control (ACC) system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have a collision. Always leave
the system off when you are not using it.
WARNING!
In Fixed Speed Cruise Control mode, the system will not
react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound even
if you are too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be sure to
maintain a safe distance between your vehicle and the
vehicle ahead. Always be aware which mode is
selected.

150STARTING AND OPERATING
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and a chime will sound when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
display “ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. ice and snow, or tunnels with
reflective tiles). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning is active, Fixed Speed Cruise Control is still
available.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the camera in the
center of the windshield, on the forward side of the
rearview mirror. To keep the ACC system operating properly, it is important
to note the following maintenance items:

Always keep the sensor clean. Carefully clear the wind-
shield.
 Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
 Do not attach or install any accessories near the
sensor, including transparent material. Doing so could
cause an ACC system failure or malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:
 If the “ACC/FCW Unavailable Wipe Front Radar Sensor”
message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at an
authorized dealer.
 Installing a snowplow, front-end protector, an after -
market grille or modifying the grille is not recom -
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and a chime will sound
when conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain and fog.
The ACC system may also become temporarily blinded due
to obstructions, such as mud, dirt, or ice on windshield,
driving directly into the sun and fog on the inside of glass.
In these cases, the instrument cluster display will show
“ACC/FCW Limited Functionality Clean Front Windshield”
and the system will have degraded performance.
This message can sometimes be displayed while driving in
adverse weather conditions. The ACC/FCW system will
recover after the vehicle has left these areas. Under rare
conditions, when the camera is not tracking any vehicles
or objects in its path this warning may temporarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rearview mirror. They may require
cleaning or removal of an obstruction.
When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean Front Wind -
shield” message occurs frequently (e.g. more than once
on every trip) without any snow, rain, mud, or other
obstruction, have the windshield and forward facing
camera inspected at an authorized dealer.
