CAUTION!
Refer to “Recreational Towing” in “Start-
ing And Operating” and “Towing A Dis-
abled Vehicle” in “In Case Of Emergency”
for further information.
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 up-
shifts through all forward gears. The DRIVE
position provides optimum driving character-
istics under all normal operating conditions.
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 (refer to
"AutoStick" in this section for further infor-
mation). Under these conditions, using a
lower gear will improve performance and ex-
tend transmission life by reducing excessive
shifting and heat buildup.If the transmission temperature exceeds nor-
mal operating limits, the transmission con-
troller may modify the transmission shift
schedule, reduce engine torque, and/or ex-
pand the range of torque converter clutch
engagement. This is done to prevent trans-
mission damage due to overheating.
If the transmission becomes extremely hot,
the "Transmission Temperature Warning
Light" may illuminate, and the transmission
may operate differently until the transmis-
sion cools down.
During cold temperatures, transmission op-
eration may be modified depending on en-
gine and/or 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 (and, for the
nine-speed, shifts into 8th or 9th gear), are
inhibited until the engine and/or transmis-
sion is warm (refer to the “Note” under
“Torque Converter Clutch” in this section).
Normal operation will resume once the tem-
perature(s) have risen to a suitable level.AUTOSTICK
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, elimi-
nate undesirable upshifts and downshifts,
and improve overall vehicle performance.
This system can also provide you with more
control during passing, city driving, cold slip-
pery conditions, mountain driving, trailer
towing, and many other situations.
Operation
When the gear selector is in the AutoStick
position (beside the DRIVE position), it can
be moved forward and rearward. This allows
the driver to manually select the transmission
gear being used. Moving the gear selector
forward (-) triggers a downshift and rearward
(+) an upshift. The current gear is displayed
in the instrument cluster.
In AutoStick mode, the transmission will
shift up or down when the driver moves the
gear selector rearward (+) or forward (-), un-
less an engine lugging or overspeed condition

6. Shift into the desired gear range. If the
problem is no longer detected, the trans-
mission 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 equip-
ment to assess the condition of your trans-
mission. If the transmission cannot be reset,
authorized dealer service is required.
Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic transmis-
sion on your vehicle. A clutch within the
torque converter engages automatically at
calibrated speeds. This may result in a
slightly different feeling or response during
normal operation in the upper gears. When
the vehicle speed drops or during some ac-
celerations, the clutch automatically disen-
gages.NOTE:
The torque converter clutch will not engage
until the engine and/or transmission is warm
(usually after 1 to 3 miles [2 to 5 km] of
driving). Because the engine speed is higher
when the torque converter clutch is not en-
gaged, it may seem as if the transmission is
not shifting properly when the vehicle is cold.
This is normal. The torque converter clutch
will function normally once the powertrain is
sufficiently warm.
FOUR-WHEEL DRIVE
OPERATION — IF EQUIPPED
Jeep Active Drive
Your vehicle may be equipped with a Power
Transfer Unit (PTU). This system is auto-
matic with no driver inputs or additional
driving skills required. Under normal driving
conditions, the front wheels provide most of
the traction. If the front wheels begin to lose
traction, power is shifted automatically to the
rear wheels. The greater the front wheel trac-
tion loss, the greater the power transfer to the
rear wheels.Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a
preemptive effort to improve vehicle launch
and performance characteristics.
CAUTION!
All wheels must have the same size and
type tires. Unequal tire sizes must not be
used. Unequal tire size may cause failure
of the power transfer unit.
Four Wheel Drive (4x4)
The four wheel drive (4WD) is fully automatic
in normal driving mode.
NOTE:
It is not possible to carry out the change of
mode when the vehicle exceeds the speed of
75 mph (120 km/h).
Enabling Four Wheel Drive (4x4)
The buttons for the activation of four wheel
drive are located on the device Selec-Terrain
and allow you to select the following:
•4WD LOCK
•4WD LOW — (Trailhawk models only)STARTING AND OPERATING

NOTE:
• Rock mode is only available on the vehicles
equipped with the Off-Road package.
• Activate the Hill Descent Control for steep
downhill control. See “Electronic Brake
Control System” in “Safety” for further
information.
STOP/START SYSTEM —
IF EQUIPPED
The Stop/Start function is developed to re-
duce fuel consumption. The system will stop
the engine automatically during a vehicle
stop if the required conditions are met. Re-
leasing the brake pedal, clutch pedal or
pressing the accelerator pedal will automati-
cally re-start the engine.
WARNING!
Before opening the hood, make sure that
the engine is off and that the ignition is in
the OFF mode. Follow the indications on
the plate underneath the hood. We recom-
mend that you remove the key fob if other
people remain in the vehicle. The vehicle
should only be exited after the key fob has
been removed and the ignition is on the
OFF mode. During refueling, make sure
that the engine is off (ignition device in the
OFF mode).
CAUTION!
When replacing the battery, always contact
your authorized dealer. Replace the bat-
tery with the same type (HEAVY DUTY) and
with the same specifications.
Operating Modes
Engine Stopping Mode
Models equipped with a manual transmission:
With the vehicle stopped, the engine stops
with transmission in neutral and clutch pedal
released.
Models equipped with an automatic transmission:
With vehicle at a standstill and brake pedal
pressed, the engine switches off if the gear
selector is in a position other than REVERSE.
In the event of stops uphill, the engine
switching will be disabled to activate the "Hill
Start Assist" function (works only with the
engine running).
The warning light on the instrument panel
switches on to signal that the engine was
stopped.
Engine Restarting Mode
Models equipped with manual transmission:
To restart the engine, press the clutch pedal.
161
If the vehicle does not start pressing the
clutch, place the gear selector in neutral and
repeat the procedure. If the problem persists,
contact your authorized dealer.
Models equipped with an automatic transmission:
To restart the engine, release the brake pedal.
With brake pressed, if the gear selector is in
DRIVE the engine can be restarted moving
the selector to REVERSE or NEUTRAL or
“AutoStick”.
With brake pedal pressed, if the gear selector
is in "AutoStick" mode, the engine can be
restarted moving the selector to "+" or "–", or
REVERSE or NEUTRAL.
When the engine has been stopped automati-
cally, keeping the brake pedal pressed, the
brake can be released keeping the engine off
by quickly shifting the gear selector to PARK.
To restart the engine, just move the selector
out of PARK.

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left
to clear the area around the front wheels. For
vehicles with automatic transmission, push
and hold the lock button on the gear selector.
Then shift back and forth between DRIVE and
REVERSE (for automatic transmission) or
SECOND GEAR and REVERSE (for manual
transmission) while gently pressing the ac-
celerator.
NOTE:
For vehicles with automatic transmission,
shifts between DRIVE and REVERSE can only
be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.Use the least amount of accelerator pedal
pressure that will maintain the rocking mo-
tion without spinning the wheels or racing the
engine.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your ve-
hicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
NOTE:
Push the “ESC Off” switch (if necessary), to
place the Electronic Stability Control (ESC)
system in “Partial Off” mode, before rocking
the vehicle. Refer to “Electronic Brake Con-
trol System” in “Safety” in the Owner’s
Manual for further information. Once the ve-
hicle has been freed, push the "ESC Off"
switch again to restore “ESC On” mode.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE/SECOND gear and
REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
