TRANSMISSION (IF EQUIPPED)
The Engine Stop/Start (ESS) function is designed to
reduce fuel consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Pressing the clutch pedal will
automatically restart the vehicle.
ESS vehicles have been upgraded with a heavy-duty
starter, enhanced battery, and other upgraded engine
parts, to handle the additional engine starts. Vehicles
equipped with eTorque contain a heavy duty motor generator and an additional hybrid electric battery to store
energy from vehicle deceleration for use on engine startup
after a stop as well as providing launch torque assist.
NOTE:It is recommended that Stop/Start be disabled during
off-road use.
Secondary Battery
Your vehicle may be equipped with a secondary battery
used to power the Stop/Start system and the 12 Volt
vehicle electrical system. The secondary battery is located
behind the wheel well for the front passenger wheel.

Battery Locations

AUTOSTOP MODE
The Stop/Start feature is enabled after every driver
ignition start. It will remain in STOP/START NOT READY
until you drive forward with a vehicle speed greater than
5 mph (8 km/h). At that time, the system will go into
STOP/START READY and if all other conditions are met,
can go into an STOP/START AUTO STOP ACTIVE mode.
To Activate The STOP/START AUTOSTOP ACTIVE Mode,
The Following Must Occur:
 The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster
Úpage 108.
 Vehicle speed must be less than 2 mph (3 km/h).
 The gear selector must be in the NEUTRAL position and
the clutch pedal must be fully released.
1 — Primary Battery
2 — Secondary Battery
WARNING!

Vehicles with the Stop/Start system will be equipped
with two batteries. Both the main and the supple -
mental batteries must be disconnected to
completely de-energize the 12 Volt electrical system.
 Serious injury or death could result if you do not
disconnect both batteries. To learn how to properly
disconnect, see an authorized dealer.

152STARTING AND OPERATING
To Set A Desired Speed
Turn the Cruise Control on.
NOTE:The vehicle should be traveling at a steady speed and on
level ground before pushing the SET (+) or SET (-) button.
When the vehicle has reached the desired speed, push
the SET (+) or SET (-) button and release. Release the
accelerator and the vehicle will operate at the selected
speed.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control is set, you can increase speed by
pushing the SET (+) button, or decrease speed by pushing
the SET (-) button.
U.S. Speed (mph)
 Pushing the SET (+), or SET (-) button once will result in
a 1 mph speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 mph.
 If the button is continually pushed, the set speed will
continue to adjust in 5 mph increments until the button
is released, then the new set speed will be established.
Metric Speed (km/h)
 Pushing the SET (+), or SET (-) button once will result in
a 1 km/h speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 km/h.
 If the button is continually pushed, the set speed will
continue to adjust in 10 km/h increments until the
button is released, then the new set speed will be
established.
To Accelerate For Passing
While the Cruise Control is set, press the accelerator to
pass as you would normally. When the pedal is released,
the vehicle will return to the set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to maintain the
vehicle set speed.
The Cruise Control system maintains speed up and down
hills. A slight speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES button
and release. Resume can be used at any speed above
20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, pushing the CANC (cancel)
button, or normal brake pressure while slowing the vehicle
will deactivate the Cruise Control without erasing the set
speed from memory. The following conditions will also deactivate the Cruise
Control without erasing the set speed from memory:

Vehicle parking brake is applied
 Stability event occurs
 Gear selector is moved out of DRIVE
 Engine overspeed occurs
 Clutch pedal is pressed (manual transmission only)
 Vehicle is operating at a low RPM (manual transmis -
sion only)
Pushing the on/off button or placing the ignition in the OFF
position erases the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC)
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 if your vehicle is not
equipped with ACC
Úpage 151.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or accelerate (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 modifications to
the vehicle will affect the performance of the Adaptive
Cruise Control and Forward Collision Warning system.
 Fixed Speed Cruise Control (ACC not enabled) will not
detect vehicles directly ahead of you. Always be aware
of the feature selected
Úpage 381.
WARNING!
Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose control
and have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy,
snow-covered or slippery.

STARTING AND OPERATING153
(Continued)
Adaptive Cruise Control (ACC) Operation
The buttons on the right side of the steering wheel operate
the ACC system.

Adaptive Cruise Control Buttons

Adaptive Cruise Control (ACC) Menu
The instrument cluster display will show the current ACC
system settings. The information it displays depends on
ACC system status.
Push the Adaptive Cruise Control (ACC) on/off button until
one of the following appears in the instrument cluster
display:
WARNING!
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver involve -
ment. 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 conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a colli -
sion and death or serious personal injury.
 The ACC system:
 Does not react to pedestrians, oncoming vehi -
cles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
 Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.
 Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.On vehicles with an automatic transmission, will
bring the vehicle to a complete stop while
following a vehicle ahead and hold the vehicle
for two seconds in the stop position. If the
vehicle ahead does not start moving within two
seconds, the ACC system will display a message
that the system will release the brakes and that
the brakes must be applied manually. An
audible chime will sound when the brakes are
released.
 You should not utilize the ACC system:
 When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa-
tions (i.e., in highway construction zones).
 When entering a turn lane or highway off-ramp;
when driving on roads that are winding, icy,
snow-covered, slippery, or have steep uphill or
downhill slopes.
 When towing a trailer up or down steep slopes.
 When circumstances do not allow safe driving at
a constant speed.

TOWING TIPS
Before setting out on a trip, practice turning, stopping and
backing the trailer in an area away from heavy traffic.
If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle under heavy
loading conditions, will improve performance and extend
transmission life by reducing excessive shifting and heat
buildup. This action will also provide better engine
braking.
AutoStick — If Equipped
When using the AutoStick shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or
“3” if needed to maintain the desired speed.
 To prevent excess heat generation, avoid continuous
driving at high RPM. Return to a higher gear or vehicle
speed when grade and road conditions allow.
Cruise Control — If Equipped
Do not use in hilly terrain or with heavy loads.
 When using the Cruise Control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
 Use Cruise Control in flat terrain and with light loads to
maximize fuel efficiency.
