Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected imme-
diately.

STARTING THE ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belts.
WARNING!
• When exiting the vehicle, always remove
the key fob from the vehicle and lock
your vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
• Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A
child could operate power windows,
other controls, or move the vehicle.
WARNING!
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
Normal Starting — Gasoline Engine
To Turn On The Engine Using The ENGINE
START/STOP Button
1. The transmission must be in PARK or
NEUTRAL.
2. Press and hold the brake pedal while
pushing the ENGINE START/STOP button
once.
3. The system takes over and attempts to
start the vehicle. If the vehicle fails to
start, the starter will disengage automati-
cally after 10 seconds.
4. If you wish to stop the cranking of the
engine prior to the engine starting, push
the button again.NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
To Turn Off The Engine Using ENGINE START/
STOP Button
1. Place the gear selector in PARK, then
push and release the ENGINE START/
STOP button.
2. The ignition will return to the OFF mode.
3. If the gear selector is not in PARK (with
vehicle stopped) and the ENGINE START/
STOP button is pushed once, the trans-
mission will automatically select PARK
and the engine will turn off, however the
ignition will remain in the ACC mode
(NOT the OFF mode). Never leave a ve-
hicle out of the PARK position, or it could
roll.
4. If the gear selector is in NEUTRAL, and
the vehicle speed is below 5 mph
(8 km/h), pushing the START/STOP but-
ton once will turn the engine off. The
ignition will remain in the ACC mode.
STARTING AND OPERATING
142

ALWAYS DO A VISUAL CHECKthat your vehicle
is in PARK by looking for the "P" in the
instrument cluster display and on the shifter.
As an added precaution, always apply the
parking brake when exiting the vehicle.
Normal Starting — Diesel Engine
1. The gear selector must be in the NEU-
TRAL or PARK position before you can
start the engine.
2. Place the ignition in the ON position.
3. Watch for the “Wait To Start Light” in the
instrument cluster. Refer to “Instrument
Cluster” in “Getting To Know Your Instru-
ment Panel” for further review. It will glow
for two to ten seconds or more, depending
on engine temperature. When the “Wait
To Start Light” goes out, the engine is
ready to start.
4. Tip Start Feature
Do notpress the accelerator. Cycle the
ignition to the START position and then
release it. The starter motor will continue
to run, and it will automatically disengage
when the engine is running. If the engine
fails to start, the starter will disengageautomatically in 25 seconds. If this oc-
curs, cycle the ignition to the LOCK posi-
tion, wait 25 to 30 seconds, then repeat
the “Normal Starting” procedure.
NOTE:
The starter motor may run up to 30 sec-
onds in very cold conditions until the
engine is started. The starter can be dis-
engaged by cycling the ignition to the
OFF position, if required.
5. After the engine starts, allow it to idle for
approximately 30 seconds before driving.
This allows oil to circulate and lubricate
the turbocharger.
Diesel Engine Warm-Up
Avoid full throttle operation when the engine
is cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow
the oil pressure to stabilize as the engine
warms up.NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 rpm during the
warm-up period, especially in cold, ambient
temperature conditions.
If temperatures are below 32°F (0°C), oper-
ate the engine at moderate speeds for five
minutes before full loads are applied.
Diesel Engine Idling — In Cold Weather
Avoid prolonged idling in ambient tempera-
tures below 0°F (-18°C). Long periods of
idling may be harmful to your engine because
combustion chamber temperatures can drop
so low that the fuel may not burn completely.
Incomplete combustion allows carbon and
varnish to form on piston rings and injector
nozzles. Also, the unburned fuel can enter
the crankcase, diluting the oil and causing
rapid wear to the engine.

WARNING!
could accelerate quickly forward or in
reverse. You could lose control of the
vehicle and hit someone or something.
Only shift into gear when the engine is
idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle
could injure those in or near the vehicle.
As with all vehicles, you should never
exit a vehicle while the engine is run-
ning. Before exiting a vehicle, always
come to a complete stop, then apply the
parking brake, shift the transmission
into PARK, and turn the ignition OFF.
When the ignition is in the OFF mode,
the transmission is locked in PARK, se-
curing the vehicle against unwanted
movement.
• When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle un-

attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
gear selector.
• Do not leave the key fob in or near the
vehicle (or in a location accessible to
children), and do not leave the ignition
in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
Ignition Park Interlock
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to
be in PARK before the ignition can be turned
to the OFF mode. This helps the driver avoid
inadvertently leaving the vehicle without
placing the transmission in PARK. This sys-
tem also locks the transmission in PARK
whenever the ignition is in the OFF mode.NOTE:
The transmission is NOT locked in PARK
when the ignition is in the ACC mode (even
though the engine will be off). Ensure that
the transmission is in PARK, and the ignition
isOFF(not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must
be running and the brake pedal must be
pressed. The brake pedal must also be
pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or
moving at low speeds.
Eight–Speed Automatic Transmission
Your vehicle is equipped with a fuel efficient
8 speed transmission. The gear selector is
located in the center console.
STARTING AND OPERATING

For additional information on the appropriate
use of each transfer case mode position, see
the information below:
2H
Rear Wheel Drive High Range — This range is
for normal street and highway driving on dry,
hard surfaced roads.
4H
Four-Wheel Drive High Range — This range
maximizes torque to the front driveshaft,
forcing the front and rear wheels to rotate at
the same speed. This range provides addi-
tional traction for loose, slippery road sur-
faces only.
NEUTRAL (N)
WARNING!
You or others could be injured or killed 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
WARNING!
allow the vehicle to roll, even if the auto-
matic transmission is in PARK. The park-
ing brake should always be applied when
the driver is not in the vehicle.
Neutral — This range disengages both the
front and rear driveshafts from the pow-
ertrain. To be used for flat towing behind
another vehicle.
Refer to “Recreational Towing” in “Starting
And Operating” for further information.
4L
Four-Wheel Drive Low Range — This range
provides low speed four-wheel drive. It maxi-
mizes torque to the front driveshaft, forcing
the front and rear wheels to rotate at the same
speed. This range provides additional trac-
tion and maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
The transfer case is intended to be driven in
the 2H position for normal street and highway
conditions, such as hard-surfaced roads.In the event that additional traction is re-
quired, the transfer case 4H and 4L positions
can be used to lock the front and rear drive-
shafts together, forcing the front and rear
wheels to rotate at the same speed. The 4H
and 4L positions are intended for loose, slip-
pery road surfaces only and not intended for
normal driving. Driving in the 4H and 4L
positions on hard-surfaced roads will cause
increased tire wear and damage to the drive-
line components. Refer to “Shifting Proce-
dures” in this section for further information
on shifting into 4H or 4L.
The instrument cluster alerts the driver that
the vehicle is in four-wheel drive, and the
front and rear driveshafts are locked together.
The light will illuminate when the transfer
case is shifted into the 4H position.
When operating your vehicle in 4L, the en-
gine speed will be approximately three times
(four times for Rubicon models) that of the
2H or 4H positions at a given road speed.
Take care not to overspeed the engine.

speed. This range provides additional trac-
tion and maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
This transfer case is designed to be driven in
the two-wheel drive position (2WD) or four-
wheel drive position (4WD AUTO) for normal
street and highway conditions on dry hard
surfaced roads. Driving the vehicle in 2WD
will have greater fuel economy benefits as the
front axle is not engaged in 2WD.
For variable driving conditions, the 4WD
AUTO mode can be used. In this mode, the
front axle is engaged, but the vehicle's power
is sent to the rear wheels. Four-wheel drive
will be automatically engaged when the ve-
hicle senses a loss of traction. Because the
front axle is engaged, this mode will result in
lower fuel economy than the 2WD mode.
In the event that additional traction is re-
quired, the transfer case 4H and 4L positions
can be used to lock the front and rear drive-
shafts together, forcing the front and rear
wheels to rotate at the same speed. The 4H
and 4L positions are intended for loose, slip-
pery road surfaces only and not intended fornormal driving. Driving in the 4H and 4L
positions on hard-surfaced roads will cause
increased tire wear and damage to the drive-
line components. Refer to “Shifting Proce-
dures” in this section for further information
on shifting into 4H or 4L.
The instrument cluster alerts the driver that
the vehicle is in four-wheel drive, and the
front and rear driveshafts are locked together.
The light will illuminate when the transfer
case is shifted into the 4H position.
When operating your vehicle in 4L, the en-
gine speed will be approximately three times
(four times for Rubicon models) that of the
2H or 4H positions at a given road speed.
Take care not to overspeed the engine.
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause dam-
age to the transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.Shifting Procedures
2H To 4H Auto Or 4H Auto To 2H
Shifting between 2H and 4H Auto can be
made with the vehicle stopped or in motion.
The preferred shifting speed would be 0 to
45 mph (72 km/h). With the vehicle in mo-
tion, the transfer case will engage/disengage
faster if you momentarily release the accel-
erator pedal after completing the shift. Do
not accelerate while shifting the transfer
case. Apply a constant force when shifting
the transfer case lever.
2H/4H Auto To 4H Part Time Or 4H Part Time
To 2H/4H Auto
Shifting between 2H/4H AUTO to 4H PART
TIME can be made with the vehicle stopped
or in motion. The preferred shifting speed
would be 0 to 45 mph (72 km/h). With the
vehicle in motion, the transfer case will
engage/disengage faster if you momentarily
release the accelerator pedal after complet-
ing the shift. Do not accelerate while shifting
the transfer case. Apply a constant force
when shifting the transfer case lever.

Axle Lock (Tru-Lok) — Rubicon Models
The AXLE LOCK switch is located on the
instrument panel (to the right of the steering
column).
This feature will only activate when the fol-
lowing conditions are met:
• Ignition in RUN position, vehicle in 4L
(Low) range.
• Vehicle speed should be 10 mph (16 km/h)
or less.• Both right and left wheels on axle are at the
same speed.
To activate the system, push the AXLE LOCK
switch down to lock the rear axle only (the
“REAR ONLY” will illuminate), push the
switch up to lock the front axle and rear axle
(the “FRONT + REAR” will illuminate). When
the rear axle is locked, pushing the bottom of
switch again will lock or unlock the front axle.
NOTE:
The indicator lights will flash until the axles
are fully locked or unlocked.
To unlock the axles, push the AXLE LOCK
OFF button.
Axle lock will disengage if the vehicle is taken
out of 4L (Low) range, or the ignition switch is
turned to the OFF position.
The axle lock disengages at speeds above
30 mph (48 km/h), and will automatically
re-lock once vehicle speed is less than
10 mph (16 km/h).
Electronic Sway Bar Disconnect — If
Equipped
Your vehicle may be equipped with an elec-
tronic disconnecting stabilizer/sway bar. This
system allows greater front suspension travel
in off-road situations.
This system is controlled by the SWAY BAR
switch located on the instrument panel (to
the right of the steering column).
