2011 JEEP WRANGLER Four wheel drive

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.
ELECTRONIC SWAY BAR
DISCONNECT – RUBICON
ONLY
Off-Road
• Press the SWAY BAR switch, locatedon the instrument panel (to the left of
the steering column), once to
disconnect the Sway Bar.
• The Sway Bar indicator light will illuminate in the instrument cluster.
On-Road
• Press the SWAY BAR switch asecond time to reconnect the Sway
Bar.
• The Sway Bar should remain in on-road mode during normal driving
conditions.
OFF-ROAD CAPABILITIES
49

OVERDRIVE OFF SWITCH
• Overdrive can be locked out bypressing the O/D OFF switch located
on the center console. An indicator
light in the instrument cluster will
illuminate to show that the switch has
been activated. Pressing the switch a
second time restores the Overdrive
function.
• When frequent transmission shifting occurs while using Overdrive, such as
when operating the vehicle under
heavy load conditions (for example, in
hilly terrain, strong head winds, or
trailer towing), turning off overdrive will
improve performance and extend
transmission life by reducing
excessive shifting and heat buildup.
RECREATIONAL TOWING
(BEHIND MOTORHOME)
Towing - Two-Wheel Drive
Models
• Recreational towing with all fourwheels on the ground is allowed
ONLY if the rear driveshaft is
removed. See your authorized dealer
or refer to the Service Manual. Towing
with the rear wheels on the ground
while the driveshaft is connected can
result in severe transmission damage. • The parking brake must be firmly
engaged and the wheels chocked
during driveshaft removal and
installation. The parking brake must
remain engaged unless the vehicle is
securely and properly connected to
the tow vehicle, or the driveshaft is
completely reinstalled. See your
authorized dealer for proper driveshaft
removal and reinstallation procedures,
including flange orientation/alignment,
use of thread-locking compound,
proper bolt torque specifications, etc.
Towing - Four-Wheel Drive
Models
NOTE: The transfer case must be shifted
into N (Neutral), automatic transmission
must be shifted into PARK,and manual
transmission must be placed in gear (NOT
in NEUTRAL) for recreational towing.
• Bring the vehicle to a complete stop,turn off the engine and press and hold
the brake pedal.
• Shift the automatic transmission into NEUTRAL or depress the clutch
pedal on a manual transmission.
• Shift the transfer case lever into N (Neutral).
• Start the engine and shift the transmission into REVERSE.
• Release the brake pedal (and clutch pedal on manual transmissions) for
five seconds and ensure that there is
no vehicle movement.
• Repeat the previous step with automatic transmission in DRIVE or
manual transmission in first gear.
• Turn OFF the engine and leave the ignition switch in the unlocked OFF
position.
• Firmly apply the parking brake and shift the transmission into PARK or
place manual transmission in gear
(NOT in Neutral).
UTILITY
52

• Using a screwdriver or similar tool, press and hold the override tab through theaccess port on the center console.
• Move the shift lever into the NEUTRAL position.
• The vehicle may then be started in NEUTRAL.
• Reinstall the override cover.
TOWING A DISABLED VEHICLE
• The manufacturer requires towing your vehicle with all four wheels OFFthe 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
overheating 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).
