transmission JEEP GRAND CHEROKEE 2012 WK2 / 4.G Owner's Manual

WARNING!
You or others could be injured if you leave the vehicle unattended
with the transfer case in the NEUTRAL position without first fully
engaging the parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from the powertrain
and will allow the vehicle to move even if the transmission is in PARK.
The parking brake should always beapplied when the driver is not in
the vehicle.

AUTOSTICK®
• AutoStick® is a driver-interactivetransmission feature that offers
manual gear shifting to provide
youwithmorecontrolofthe
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
• When the shift lever is in the DRIVE position, the transmission willoperate automatically, shifting between the five available gears. To
engage AutoStick®, simply tap the shift lever to the right or left (+/-)
while in the DRIVE position, or tap one of the steering wheel-mounted
shift paddles (+/-). Tapping (-) to enter AutoStick® mode will downshift
the transmission to the next lower gear, while using (+) to enter
AutoStick® mode will retain the current gear. When AutoStick® is active,
the current transmission gear is displayed in the instrument cluster. In
AutoStick® mode, the transmission will shift up or down when (+/-) is
manually selected by the driver (using the shift lever, or the shift
paddles), unless an engine lugging or overspeed condition would result.
It will remain in the selected gear until another upshift or downshift is
chosen, except as described below:
• Normally, in AutoStick® mode, the transmission will automatically shift up when maximum engine speed is reached. If, h owever, AutoStick® is
engaged while in SPORT mode, the transmission will remain in the
selected gear even when maximum engine speed is reached. The
transmission will upshift only when commanded by the driver.
• 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
transmission as the vehicle is accelerated.
• You can start out in first or second gear. Tapping (+) (at a stop) will allow starting in second gear. Starting out in second gear is helpful in
snowy or icy conditions.
• The system will ignore attempts to upshift at too low of a vehicle speed.
• Avoid using speed control when AutoStick® is engaged.

• Transmission shifting will be more noticeable when AutoStick® isengaged.
• To disengage AutoStick® mode, hold the shift lever to the right or press and hold the (+) shift paddle until “D” is once again displayed in the
instrument cluster. You can shift in or out of the AutoStick® mode at any
time without taking your foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a slippery surface.
The drive wheels could lose their grip and the vehicle could skid,
causing a collision or personal injury.
SELEC-TRACK™
• Selec-Track™ combines the capabilities of the vehicle control systems,along with driver input, to provide the best performance for all terrains.
• Rotate the mode control knob toselect the following Selec-Track™
positions:
• Sport – Dry weather, on-road
calibration. Performance based
tuning that provides a rear wheel
drive feel but with improved
handling and acceleration over a
two-wheel drive vehicle. The
active suspension system will be
in Semi Firm mode, and a green
flag will light up in the instrument
cluster.
• Snow – Tuning set for additional stability in inclement weather. Use on
and off road on loose traction surfaces such as snow.
• Auto – Fully automatic full time four-wheel drive operation can be used
on and off road. This position balances traction with seamless steering
feel to provide improved handling and acceleration over two-wheel
drive vehicles.
• Track – This position offers track road calibration for use on high
traction surfaces. Driveline is maximized for traction. Some binding may
be felt on less forgiving surfaces.
• To w – Use this mode for towing. Vehicle suspension will go to Firm
mode and peak power will be limited in the engine controls.

IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential foroverheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending
overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this
heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to high. This allows the heater core
to act as a supplement to the radiator and aids in removing heat from the
engine cooling system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the
temperature gauge reads 240°F (116 °C) or greater pull over and stop
the vehicle. Idle the vehicle with the air conditioner turned off until the
pointer drops back into the normal range 200–230°F (93–110°C). If
the pointer remains at 240°F (116°C) or greater and you hear a chime,
turn the engine off immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze)
or steam from your radiator. If you see or hear steam coming from
under the hood, do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure cap when the
radiator or coolant bottle is hot.

Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped end of the nuttoward the wheel. Lightly tighten the lug nuts.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased leverage. Tighten the lug nuts in a star
pattern until each nut has been tightened twice. The correct tightness of
each lug nut is 110 ft/lbs (150 N·m). If in doubt about the correct
tightness, have them checked with a torque wrench by your authorized
dealer or service station.
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that all lug nuts are properly seated against the wheel.
CAUTION!
• Do not attempt to raise the vehicle by jacking on locations otherthan those indicated in the Jacking Instructions for this vehicle.
• Be sure to mount the spare tire with the valve stem facing outward. The vehicle could be damaged if the spare tire is mounted
incorrectly.
WARNING!
• Do not attempt to change a tire on the side of the vehicle close tomoving traffic. Pull far enough off the road to avoid the danger of
being hit when operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never put any
part of your body under a vehicle that is on a jack. If you need to
get under a raised vehicle, take it to a service center where it can be
raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The
vehicle should be jacked on a firm level surface only. Avoid ice or
slippery areas.
• Always park on a firm, level surface as far from the edge of the
roadway as possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in PARK.
