(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 “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 be controlling
the distance between your vehicle and the vehicle
ahead. The vehicle speed will only be determined by
the position 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 gear selector is removed from the DRIVE position
WARNING!
Leaving the Adaptive Cruise Control (ACC) system on

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.

144STARTING AND OPERATING
NOTE:
If your vehicle is at a standstill for longer than two
seconds, the system will hold brake pressure for up to
10 minutes. If no driver action is taken after the
10 minutes, the Electric Park Brake will be applied and
the ACC system will cancel.
 While ACC is holding your vehicle at a standstill (or the
vehicle is traveling below 3 mph (5 km/h), and the
driver seat belt is unbuckled or the driver door is
opened, the Electric Park Brake will be applied and the
ACC system will cancel.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC 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 this message and the system will deactivate. This 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 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 center of the
vehicle behind the lower grille.
To keep the ACC System operating properly, it is important
to note the following maintenance items:

Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
 Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
 If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
 Do not attach or install any accessories near the
sensor, including transparent material or aftermarket
grilles. 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 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 operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC 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 and fog on the inside of
glass. In these cases, the instrument cluster display will
read “ACC 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 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.
WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or
objects in the path of the vehicle. Failure to follow these
warnings can result in a collision and death or serious
personal injury.

STARTING AND OPERATING161
The system may not work in all conditions (e.g. environ -
mental conditions such as heavy rain, snow, etc., or if
searching for a parking space that has surfaces that
will absorb the ultrasonic sensor waves).
 New vehicles from the dealership must have at least
30 miles (48 km) accumulated before the ParkSense
Active Park Assist system is fully calibrated and
performs accurately. This is due to the system’s
dynamic vehicle calibration to improve the perfor -
mance of the feature. The system will also continuously
perform the dynamic vehicle calibration to account for
differences such as over or under inflated tires and
new tires.

TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.

Weight Distribution

Consider the following items when computing the weight
on the rear axle of the vehicle:
The tongue weight of the trailer.
 The weight of any other type of cargo or equipment put
in or on your vehicle.
 The weight of the driver and all passengers.
NOTE:Remember that everything put into or on the trailer adds
to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the Tire And Loading Information Placard for the
maximum combined weight of occupants and cargo for
your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of the new vehicle drivetrain
components, the following guidelines are recommended. Perform the maintenance listed in the Scheduled
Servicing
Úpage 309. When towing a trailer, never
exceed the GAWR or GCWR ratings.
WARNING!
Always load a trailer with 60% of the weight in the front
of the trailer. This places 10% of the GTW on the tow
hitch of your vehicle. Loads balanced over the wheels or
heavier in the rear can cause the trailer to sway
severely side to side which will cause loss of control of
the vehicle and trailer. Failure to load trailers heavier in
front is the cause of many trailer collisions.CAUTION!
 Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
 Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering cargo
that is not fully secured, dynamic load shifts can
occur that may be difficult for the driver to control.
You could lose control of your vehicle and have a
collision.
 When hauling cargo or towing a trailer, do not over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, chassis structure or tires.
 Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
 Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in PARK
(P). For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL (N). Always, block or
"chock" the trailer wheels.
 GCWR must not be exceeded.

STARTING AND OPERATING187

Integrated Trailer Brake Module (ITBM)

The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to activate
power to the trailer's electric brakes independent of the
tow vehicle's brakes. If the manual brake control lever is
activated while the brake is also applied, the greater of the
two inputs determines the power sent to the trailer brakes.
The trailer and the vehicle's brake lamps will come on
when either vehicle braking or manual trailer brakes are
applied. Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection status.
If no electrical connection is detected after the ignition is
turned on, pushing the GAIN adjustment button or sliding
the manual brake control lever will display the GAIN
setting for 10 seconds and the Trailer Brake Status
Indicator Light will not be displayed.
If a fault is detected in the trailer wiring or the ITBM, the
Trailer Brake Status Indicator Light will flash.
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control power
output to the trailer brakes in 0.5 increments. The GAIN
setting can be increased to a maximum of 10 or
decreased to a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer brake control for
the specific towing condition and should be changed as
towing conditions change. Changes to towing conditions
include trailer load, vehicle load, road conditions and
weather.
Adjusting GAIN
NOTE:This should only be performed in a traffic free environment
at speeds of approximately 20–25 mph (30–40 km/h).

1. Make sure the trailer brakes are in good working condition, functioning normally and properly
adjusted. See a trailer dealer if necessary.

2. Hook up the trailer and make the electrical connections according to the trailer manufacturer's
instructions. 3. When a trailer with electric/EOH brakes is plugged in,
the trailer connected message should appear in the
instrument cluster display (if the connection is not
recognized by the ITBM, braking functions will not be
available), the GAIN setting will illuminate and the
correct type of trailer must be selected from the
instrument cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the “Trailer Brake Type” appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake Type appears
on the screen.
8. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20–25 mph
(30–40 km/h) and squeeze the manual brake
control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier trailer,
trailer wheel lockup may not be attainable even with the
maximum GAIN setting of 10.

194STARTING AND OPERATING
When To Use 4WD LOW — If Equipped
When off-road driving, shift to 4WD LOW for additional
traction. This range should be limited to extreme
situations such as deep snow, mud, or sand where
additional low speed pulling power is needed. Vehicle
speeds in excess of 25 mph (40 km/h) should be avoided
when in 4WD LOW.
Driving Through Water
Although your vehicle is capable of driving through water,
there are a number of precautions that must be
considered before entering the water.
NOTE:Your vehicle is capable of water fording in up to 20 inches
(51 cm) of water, while crossing small rivers or streams. To
maintain optimal performance of your vehicle's heating
and ventilation system it is recommended to switch the
system into recirculation mode during water fording. Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle. If you must
drive through water, try to determine the depth and the
bottom condition (and location of any obstacles) prior to
entering. Proceed with caution and maintain a steady
controlled speed less than 5 mph (8 km/h) in deep water
to minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off),
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing water avoid
depths in excess of 9 inches (23 cm). The flowing water
can erode the streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 24 inches
(60 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed is 5 mph (8 km/h).Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to ensure the fluids have not been
contaminated. Contaminated fluid (milky, foamy in
appearance) should be flushed/changed as soon as
possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary
Úpage 129. Only shift into a lower gear to maintain
forward motion. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the conditions
at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
FIRST gear and 4WD LOW for very steep hills.
WARNING!
Do not drive in 4WD LOW on dry pavement; driveline
damage may result. 4WD LOW locks front and rear
drivelines together and does not allow for differential
action between the front to rear driveshafts. Driving in
4WD LOW on pavement will cause driveline binding;
use only on wet or slippery surfaces.
CAUTION!
When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as
a precaution, and check all fluids afterward. Driving
through water may cause damage that may not be
covered by the New Vehicle Limited Warranty.

23_WS_OM_EN_USC_t.book Page 194

STARTING AND OPERATING195
If you stall or begin to lose forward motion while climbing
a steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine, and
shift into REVERSE (R). Back slowly down the hill, allowing
the compression braking of the engine to help regulate
your speed. If the brakes are required to control vehicle
speed, apply them lightly and avoid locking or skidding the
tires.
Remember, never drive diagonally across a hill. Always
drive straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain forward motion
by turning the front wheels slowly. This may provide a fresh
“bite” into the surface and will usually provide traction to
complete the climb.Traction Downhill
When descending mountains or hills, use Hill Descent
Control or Selec-Speed Control to avoid repeated heavy
braking.
If not equipped with Hill Descent Control or Selec-Speed
Control use the following procedure:
Shift the transmission into a low gear, and the transfer
case into 4WD LOW range. Let the vehicle go slowly down
the hill with all four wheels turning against engine
compression drag. This will permit you to control the
vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
 Inspect the radiator for mud and debris and clean as
required. 
Check threaded fasteners for looseness, particularly
on the chassis, drivetrain components, steering, and
suspension. Retighten them, if required, and torque to
the values specified in the Service Manual.
 Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
 After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
 If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
WARNING!
If the engine stalls, you lose forward motion, or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and rolling
the vehicle. Always back carefully straight down a hill in
REVERSE gear. Never back down a hill in NEUTRAL
using only the brake.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in dirty
conditions, get your brakes checked and cleaned as
necessary.
