2008 JEEP WRANGLER UNLIMITED stop start

The park lamps will remain illuminated to indicate that
the vehicle has remote started and the engine is running.
The lamps will turn off when the ignition is turned to
RUN or the remote start is cancelled.
To enter the vehicle while the engine is running during a
remote start, you must first unlock the vehicle using the
UNLOCK button on the key fob. Then, prior to the end of
the 15 minute cycle, insert the key into the ignition switch
and turn the switch to the ON position, otherwise the
engine will cancel remote start and automatically turn
off.
Remote start will also cancel if any of the following occur:
•If the engine stalls or RPM exceeds 2500
•Any engine warning lamps come on
•The hood is opened
•The hazard switch is pressed
•The transmission is moved out of PARK
The vehicle can be started remotely up to a maximum of
two times. The vehicle is also allowed a maximum of one
failed start, where the remote start sequence was initiated
but the engine stopped cranking without starting. After
either of these conditions, or if the Security Alarm is
alarming, or if the PANIC button was pressed, the vehicle
must be reset by inserting a valid key into the ignition
and moving it to the RUN position, then back to LOCK.
DOORS
The vacuum fluorescent (VF) display located in the
odometer area will display the word “door” as an
indication of a door ajar or not completely closed. When
the vehicle is not moving and the door is ajar or not
completely closed, the VF display will show the word
“door.”
26 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
A belt that is buckled into the wrong buckle will not
protect you properly. The lap portion could ride too high
on your body, possibly causing internal injuries. Always
buckle your belt into the buckle nearest you.
A belt that is loose will not protect you as well. In a
sudden stop you could move too far forward, increasing
the possibility of injury. Wear your seat belt snugly.
A belt that is worn under your arm is very dangerous.
Your body could strike the inside surfaces of the vehicle
in a collision, increasing head and neck injury. A belt
worn under the arm can cause internal injuries. Ribs
aren’t as strong as shoulder bones. Wear the belt over
your shoulder so that the strongest bones will take the
force in a collision.
A shoulder belt placed behind will not protect you from
injury during a collision. You are more likely to hit your
head in a collision if you do not wear your shoulder belt.
The lap and shoulder belt are meant to be used together.
4. Position the lap belt across your thighs, below your
abdomen. To remove slack in the lap belt portion, pull up
on the shoulder belt. To loosen the lap belt if it is too tight,
tilt the latch plate and pull on the lap belt. A snug belt
reduces the risk of sliding under the belt in a collision.
NOTE:The Seat Belt Indicator Light will remain on
until the driver’s seat belt is buckled.
44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short time, adjust the ventilation system
to force fresh, outside air into the vehicle.
•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside the
vehicle. Otherwise poisonous gases could be drawn
into the vehicle.
•On hardtop models, keep the tailgate window closed
when driving your vehicle. On fabric top models, do
not drive with the rear window curtain up unless the
side curtains are also open. This will prevent carbon
monoxide and other poisonous exhaust gases from
entering the vehicle.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for
cuts, frays and loose parts. Damaged parts must be
replaced immediately. Do not disassemble or modify the
system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Fluids and
Genuine Parts in Section 7 for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift intoNEUTRAL (N) and depress the accelerator slightly for
fast idle operation to increase coolant flow and fan speed.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
266 UNDERSTANDING YOUR INSTRUMENT PANEL

rear wheels to rotate at the same speed. This is accom-
plished by simply moving the shift lever to one of these
positions. The 4H and 4L positions are intended for loose,
slippery 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 driveline components.
The 4WD Indicator Light (located in 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.
NOTE:Do not attempt to shift when only the front or
rear wheels are spinning. The transfer case is not
equipped with a synchronizer, and the front and rear
driveshaft speeds must be equal for a shift to take place.
Shifting while only the front or rear wheels are spinning
can cause damage to the transfer case. When operating your vehicle in 4L, the engine 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 damage 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.
286 STARTING AND OPERATING

N (Neutral) Position
This range disengages the front and rear driveshafts from
the powertrain. To be used for flat towing behind another
vehicle. Refer to “Recreational Towing” in Section 5 of
this manual.
4L Position
This range locks the front and rear driveshafts together,
forcing the front and rear wheels to rotate at the same
speed. This range (4L) provides additional traction and
maximum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).
The 4WD Indicator Light (located in the instrument
cluster) will illuminate when the transfer case is shifted
into the 4L position.
Shifting Procedure
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made with the
vehicle stopped or in motion. If the vehicle is in motion,
shifts can be made up to 50 mph (80 km/h). With the
vehicle in motion, the transfer case will engage/
disengage faster if you momentarily release the accelera-
tor pedal after completing the shift. Apply a constant
force when shifting the transfer case lever.
288 STARTING AND OPERATING

Mud
Deep mud creates a great deal of suction around the tires
and is very difficult to get through. You should use 2nd
gear (manual transmission), or DRIVE (automatic trans-
mission), with the transfer case in the 4L (Low) position
to maintain your momentum. If you start to slow to a
stop, try turning your steering wheel no more than a 1/4
turn quickly back and forth for additional traction. Mud
holes pose an increased threat of vehicle damage and
getting stuck. They are normally full of debris from
previous vehicles getting stuck. As a good practice before
entering any mud hole, get out and determine how deep
it is, if there are any hidden obstacles and if the vehicle
can be safely recovered if stuck.
Sand
Soft sand is very difficult to travel through with full tire
pressure. When crossing soft sandy spots in a trail
maintain your vehicle’s momentum and do not stop. The
key to driving in soft sand is using the appropriate tirepressure, accelerating slowly, avoiding abrupt maneu-
vers and maintaining the vehicle’s momentum. If you are
going to be driving on large soft sandy areas or dunes,
reduce your tire pressure to a minimum of 15 psi (103
kPa) to allow for a greater tire surface area. Reduced tire
pressure will drastically improve your traction and han-
dling, while driving on the soft sand, but you must return
the tires to normal air pressure before driving on pave-
ment or other hard surfaces. Be sure you have a way to
reinflate the tires prior to reducing the pressure.

WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle, which may result in
severe injury. Always back carefully straight down a
hill in REVERSE gear. Never back down a hill in
NEUTRAL using only the vehicle brakes. Never
drive diagonally across a hill, always drive straight
up or down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible, and only
be attempted when necessary in a safe responsible man-
ner. You should only drive through areas which are
designated and approved. You should tread lightly andavoid damage to the environment. You should know
your vehicles abilities and be able to recover it if some-
thing goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do
not attempt to restart it. Determine if it has ingested
water first. The key to any crossing is low and slow. Shift
into 1st gear (manual transmission), or DRIVE (automatic
transmission), with the transfer case in the 4L (Low)
position and proceed very slowly with a constant slow
speed {3 to 5 mph (5 to 8 km/h) maximum} and light
throttle. Keep the vehicle moving; do not try to accelerate
through the crossing. After crossing any water higher
than the bottom of the axle differentials, you should
inspect all of the vehicle fluids for signs of water inges-
tion.
