four wheel drive 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

TOWING A DISABLED VEHICLE
• The manufacturer requires towing your vehicle with all four wheelsOFFthe ground
using a flatbed.
CAUTION!
Towing this vehicle using any other method could result in extensive damage to the
transfer case and/or transmission.
FREEING A STUCK VEHICLE
• If your vehicle becomes stuck in mud, sand or snow, it can often be moved by a rocking motion. Turn your steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE/1st gear and REVERSE.
Using minimal accelerator pedal pressure to maintain the rocking motion, without
spinning the wheels, is most effective.
NOTE:
If your vehicle is equipped with Traction Control or Electronic Stability Control (ESC),
turn the system OFF before attempting to “rock” the vehicle.
CAUTION!
• Racing the engine or spinning the wheels may lead to transmission overheating and failure. Allow the engine to idle with the shift lever in NEUTRAL for at least
one minute after every five rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure during prolonged efforts to free
a stuck vehicle.
• When “rocking” a stuck vehicle by moving between DRIVE/1st 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 damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).
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 vehicle'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.
