manual transmission JEEP WRANGLER 2012 JK / 3.G User Guide

COMMAND-TRAC®/ROCK-TRAC®
• The transfer case provides four
mode positions: 2H (Two-wheel
drive high range), 4H (Four-wheel
drive high range), N (Neutral), and
4L (Four-wheel drive low range).
• The transfer case is intended to be
driven in the 2H position for
normal street and highway
conditions such as hard-surfaced
roads.
• Shifting between 2H and 4H can
be made with the vehicle stopped
or in motion. Shift the transfer
case lever firmly to 4H at any
speed up to 50 mph (80 km/h).
• Shifting between 4H and 4L can be made with the vehicle rolling at 2 to
3 mph (3 to 5 km/h). Shift the automatic transmission into NEUTRAL or
fully depress the clutch pedal on a manual transmission. Shift the transfer
case lever firmly to 4L (do not pause with the transfer case in
NEUTRAL). Once the shift is completed, place the automatic
transmission into DRIVE or release the clutch pedal on a manual
transmission.
NOTE:To enhance off-road performance in 4L mode, manual transmission
vehicles will start regardless of whether or not the clutch pedal is depressed.
AXLE LOCK (TRU-LOK®) RUBICON ONLY
• The AXLE LOCK switch is located on the instrument panel (to the left of
the steering column).
• This feature will only activate when the following conditions are met:
• Key in ignition, vehicle in 4L (Low) range.
• Vehicle speed at 10 mph (16 km/h) or less.
• Press the bottom of the AXLE LOCK switch once to lock the rear axle
only and a second time to lock the front axle (the rear and front axle lock
indicator lights will illuminate).
• To unlock the axles, press the top of the AXLE LOCK switch.
• The indicator light will flash until the axles are fully locked or unlocked.

CAUTION!
• It is necessary to follow these steps to be certain that the transfer
case is fully in NEUTRAL (N) before recreational towing to prevent
damage to internal parts.
• Damage to the transmission may occur if the transmission is shifted
into PARK with the transfer case in NEUTRAL (N) and the engine
running. With the transfer case in NEUTRAL (N) ensure that the
engine is OFF prior to shifting the transmission into PARK.
• Front or rear wheel lifts should not be used. Internal damage to the
transmission or transfer case will occur if a front or rear wheel lift is
used when recreational towing.
• Tow only in the forward direction. Towing this vehicle backwards
can cause severe damage to the transfer case.
• Automatic transmissions must be placed in the PARK position for
recreational towing.

CAUTION!(Continued)
• Manual transmissions must be placed in gear (not in Neutral) for
recreational towing.
• Before recreational towing, perform the procedure outlined under
“Shifting Into NEUTRAL (N)” to be certain that the transfer case is
fully in NEUTRAL (N). Otherwise, internal damage will result.
• Towing this vehicle in violation of the above requirements can cause
severe transmission and/or transfer case damage. Damage from
improper towing is not covered under the New Vehicle Limited
Warranty.
• Do not use a bumper-mounted clamp-on tow bar on your vehicle.
The bumper face bar will be damaged.
WARNING!
You or others could be injured if you leave the vehicle unattended
with the transfer case in the NEUTRAL (N) position without first fully
engaging the parking brake. The transfer case NEUTRAL (N) 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.

Preparations For Jacking
1. Park on a firm, level surface. Avoid ice or slippery areas.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Shift the automatic transmission into PARK, or a manual transmission
into REVERSE.
5. Turn the ignition to LOCK.
Block both the front and rear of the
wheel diagonally opposite of the
jacking position. For example, if
changing the right front tire, block the
left rear wheel.
NOTE:Passengers should not remain
in the vehicle when the vehicle is
being jacked.
Jacking Instructions
1. Remove the spare tire, jack and
tools from the stored location.
2. Loosen (but do not remove) the
wheel lug nuts by turning them to
the left one turn while the wheel
is still on the ground.
3. Assemble the jack and jacking
tools. Connect the jack handle
driver to the extension, then to
the lug wrench.
WHAT TO DO IN EMERGENCIES

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 95 ft/lbs (130 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 other than
those indicated in the Jacking Instructions for this vehicle.
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to
moving 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.
• Carefully follow these tire changing warnings to help prevent
personal injury or damage to your vehicle:
• Alwayspark 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; a manual transmission in REVERSE.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack.
• Only use the jack in the positions indicated and for lifting this
vehicle during a tire change.
• If working on or near a roadway, be extremely careful of motor
traffic.
