automatic transmission JEEP WRANGLER 2013 JK / 3.G User Guide

COMMAND-TRAC®/ROCK-TRAC®
• The transfer case provides four modepositions: 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 trans-
mission. 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 Run Position, 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 PARKwith 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.
• 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 be applied when the
driver is not in the vehicle.

JACKING AND TIRE CHANGING
Jack Location
• The jack and lug wrench are located in the rear storage compartment.
NOTE:
Turn the black plastic wing nut counter clockwise to loosen the jack from the storage bin.
Spare Tire Stowage
•To remove the spare tire from the car-
rier, remove the tire cover, if equipped,
and remove the lug nuts with the lug
wrench turning them counterclockwise.
NOTE:
If you have added aftermarket accesso-
ries to the spare tire mounted carrier, it
cannot exceed a gross weight of 69 lbs
(31.3 kg) including the weight of the
spare tire.
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 posi-
tion. 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.

WARNING!
• Do not attempt to change a tire on the side of the vehicle close to movingtraffic. 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:
• Always park on a firm, level surface as far from the edge of the roadwayas 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.
• To assure that spare tires, flat or inflated, are securely stowed, spares
must be stowed with the valve stem facing the ground.
• Raising the vehicle higher than necessary can make the vehicle less
stable and cause a collision. It could slip off the jack and hurt someone
near it. Raise the vehicle only enough to remove the tire.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the
wheel nuts fully until the vehicle has been lowered.
• A loose tire or jack, thrown forward in a collision or hard stop, could en-
danger the occupants of the vehicle. Always stow the jack parts and the
spare tire in the places provided.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the lug
nuts fully until the vehicle is lowered to the ground.

JUMP-STARTING
• If your vehicle has a discharged bat-tery it can be jump-started using a set
of jumper cables and a battery in an-
other vehicle or by using a portable
battery booster pack.
• Jump-starting can be dangerous if done improperly so please follow the
procedures in this section carefully.
NOTE:
When using a portable battery booster
pack follow the manufacturer’s operating
instructions and precautions.
Preparations for Jump-Start
• The battery in your vehicle is located in the right rear of the engine compartment.
• Set the parking brake, shift the automatic transmission into PARK and turn the ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• If using another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the ignition is OFF.
Jump-Starting Procedure
• Connect the positive (+)end of the jumper cable to the positive (+)post of the
discharged vehicle.
• Connect the opposite end of the positive (+)jumper cable to the positive (+)post
of the booster battery.
• Connect the negative end (-)of the jumper cable to the negative (-)post of the
booster battery.
• Connect the opposite end of the negative (-)jumper cable to a good engine ground
(exposed metal part of the discharged vehicle’s engine) away from the battery and
the fuel injection system.
• Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start the engine in the vehicle with the discharged battery.
