104STARTING AND OPERATING
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and
permits quicker starts in cold weather. Connect the
cord to a standard 110-115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
The engine block heater must be plugged in at
least one hour to have an adequate warming effect
on the engine. The engine block heater cord is located:
3.6L Engine — Bundled and strapped behind the
engine air cleaner assembly.
5.7L Engine — Bundled and strapped in front of
the power distribution center.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
Brief full-throttle acceleration within the limits of
local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
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 auto -
matic transmission 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 Ú page 255.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than 25
seconds at a time. Wait 60 seconds before
trying again.
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

21_WD_OM_EN_USC_t.book Page 104

STARTING AND OPERATING105
(Continued)
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur. For the recommended viscosity and
quality grades see Ú
page 322.
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as a problem. Please check
your oil level with the engine oil indicator often
during the break-in period. Add oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK (P) position.
The foot operated parking brake is located below
the lower left corner of the instrument panel. To
apply the parking brake, firmly push the parking
brake pedal fully. To release the parking brake,
press the parking brake pedal a second time and
let your foot up as you feel the brake disengage.
Parking Brake

When the parking brake is applied with the ignition
switch in the ON/RUN mode, the Brake Warning
Light in the instrument cluster will illuminate.
NOTE:
When the parking brake is applied and the
transmission is placed in gear, the Brake
Warning Light will flash. If vehicle speed is
detected, a chime will sound to alert the driver.
Fully release the parking brake before
attempting to move the vehicle.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application. 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.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.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 leaving 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 chil
-
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
When leaving the vehicle, always make sure
the keyless ignition node is in the OFF mode,
remove the key fob from the vehicle and lock
the vehicle.

STARTING AND OPERATING107
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be in
PARK (P) before the ignition can be turned to the
OFF mode. 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 mode.
NOTE:The transmission is NOT locked in PARK when the
ignition is in the ACC mode (even though the
engine will be off). Ensure that the transmission is
in PARK, and the ignition is OFF (not in ACC mode)
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.
FUEL ECONOMY (ECO) MODE
The Fuel Economy (ECO) mode can improve the
vehicle's overall fuel economy during normal
driving conditions. Push the ECO button in the
center stack of the instrument panel to activate or
disable ECO mode. A light on the button indicates
when ECO mode is disabled.

ECO OFF Button

When the Fuel Economy (ECO) Mode is enabled,
the vehicle control systems will change the
following:
The transmission will upshift sooner and
downshift later.
The overall driving performance will be more
conservative.
Some ECO mode functions may be temporarily
inhibited based on temperature and other
factors.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the transmis -
sion 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
mode. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
Shift into or out of PARK or REVERSE (R) only
after the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE (D) when the engine is
above idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
WARNING!
4

21_WD_OM_EN_USC_t.book Page 107

110STARTING AND OPERATING
The following indicators should be used to ensure
that you have properly engaged the transmission
into the PARK position:
When shifting into PARK, push the lock button
on the gear selector and firmly move the
selector all the way forward until it stops and is
fully seated.
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 (P) 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), use
the AutoStick shift control to select a lower gear
Ú
page 111. Under these conditions, using a lower
gear will improve performance and extend
transmission life by reducing excessive shifting
and heat buildup.
During cold temperatures, transmission operation
may be modified depending on engine and
transmission temperature as well as vehicle
speed. This feature improves warm up time of the
engine and transmission to achieve maximum
efficiency. Engagement of the torque converter
clutch is inhibited until the transmission fluid is
warm. Normal operation will resume once the
transmission temperature has risen to a suitable
level.
Manual (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of
transmission shifting (also known as AutoStick
mode Ú page 111). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL
(AutoStick) position will manually select the
transmission gear, and will display the current gear
in the instrument cluster as 1, 2, 3, etc.
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.
For Recreational Towing Ú page 153.
For Towing A Disabled Vehicle Ú page 261.

STARTING AND OPERATING111
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission may operate only in
certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the
engine may stall. In some situations, the
transmission may not re-engage if the engine is
turned off and restarted. The Malfunction Indicator
Light (MIL) may be illuminated. A message in the
instrument cluster will inform the driver of the
more serious conditions, and indicate what actions
may be necessary.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after
engine shutdown, perform this procedure only in a
desired location (preferably, at an authorized
dealer):

1. Stop the vehicle.

2. Shift the transmission into PARK (P), if
possible. If not, shift the transmission to
NEUTRAL (N). 3. Push and hold the ignition switch until the
engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission. If the transmission
cannot be reset, authorized dealer service is
required.
AutoStick — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This system can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations. Operation
In AutoStick mode, you can use the gear selector
(in the MANUAL position), or the shift paddles to
the MANUAL (M) position (beside the DRIVE (D)
position), or tap one of the shift paddles on the
steering wheel. Tapping the (-) shift paddle to enter
AutoStick mode will downshift the transmission to
the next lower gear, while tapping (+) to enter
AutoStick mode will retain the current gear. The
current transmission gear will be displayed in the
instrument cluster.
NOTE:The shift paddles (if equipped) may be disabled
using the Uconnect Personal Settings.
AutoStick mode has the following operational
benefits:
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans
-
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) at a stop will allow
starting in SECOND gear. Starting out in
SECOND gear can be helpful in snowy or icy
conditions.
4

21_WD_OM_EN_USC_t.book Page 111

112STARTING AND OPERATING
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed.
Holding the (-) paddle pressed, or holding the
gear selector in the (-) position, will downshift
the transmission to the lowest gear possible at
the current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.
To disengage AutoStick mode, return the gear
selector to the DRIVE (D) position, or press and
hold the (+) shift paddle until "D" is indicated in the
instrument cluster. You can shift in or out of
AutoStick mode at any time without taking your
foot off the accelerator pedal.
SPORT MODE — IF EQUIPPED
Your vehicle is equipped with a SPORT Mode
feature. The engine, transmission, and steering
systems are all set to their SPORT settings. SPORT
Mode will provide improved throttle response and
modified transmission shift points for an enhanced
driving experience, as well as greater amount of
steering feel. This mode may be activated and
deactivated by pushing the SPORT button on the
instrument panel switch bank.

GUIDELINES FOR TRACK USE
If your vehicle is equipped with Drive Modes,
they will alter the vehicle’s performance in
various driving situations. It is recommended
that your vehicle operates in SPORT or TRACK
modes during the track event.
Prior to each track event, verify all fluids are at
the correct levels.
Prior to each track event, verify the front and
rear brake pads have more than half pad thick -
ness remaining. If the brake pads require
changing, complete a brake burnish procedure
prior to track outing at full pace.
NOTE:Use of DOT 4 brake fluid is suggested for extended
track usage due to increased thermal capacity.
At the conclusion of each track event, it is
recommended that a brake bleed procedure is
performed to maintain the pedal feel and stop -
ping capability of your Brembo High Perfor -
mance brake system.
It is recommended that each track outing

ADAPTIVE CRUISE CONTROL (ACC) —
I
F EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently Ú page 119.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your Cruise Control. ACC
utilizes a radar sensor and a forward facing
camera designed to detect a vehicle directly ahead
of you.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or acceleration (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the mode selected
Ú page 327.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead; and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance condi -
tions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
