2008 JEEP WRANGLER UNLIMITED turn signal

Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition,
sounds a signal to remind you to remove the key.
STEERING WHEEL LOCK
Your vehicle is equipped with a passive steering wheel
lock. This lock prevents steering the vehicle without the
ignition key. If the steering wheel is moved a half turn in
either direction, and the key is not in the ignition, the
steering wheel will lock.
To Manually Lock the Steering Wheel
With the engine running, rotate the steering wheel one–
half revolution from the straight ahead position, turn off
the engine, and remove the key. Rotate the steering wheel
slightly in both directions until the lock engages.
To Release the Steering Wheel Lock
Insert the key in the ignition, and turn the wheel slightly
to the left or right, to disengage the lock.
NOTE:If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to
disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.
SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors, swing gate, and
ignition for unauthorized operation. When the alarm is
activated, the system provides both audible and visible
signals. The horn, headlights, and tail lights will sound/
flash repeatedly for three minutes. If disturbance is still
present (driver’s door, passenger door, other doors, igni-
tion) after three minutes, the headlights and tail lights
will flash for an additional 15 minutes.
NOTE:The Panic and Security alarms are quite differ-
ent. Please take a moment to activate the Panic and the
Security modes to hear the differences in the horn. In case
one should go off in the future, you will need to know
which mode has been activated in order to deactivate it.
To Set the Alarm
The alarm will set when you use the remote keyless entry
(RKE) transmitter to lock the doors and swing gate, or
when you use the power door lock switch while the door
is open. After all the doors are locked and closed, the
Sentry Key/Security Alarm Indicator Light (located on
the instrument cluster) will flash rapidly for about 16
seconds to signal that the system is arming. During this
16–second arming period, opening any door or the swing
gate will cancel the arming. If the system successfully
arms, the Sentry Key/Security Alarm Indicator Light
will flash at a slower rate to indicate the alarm is set.
To Disarm the System
To disarm the system, you will need to press the UN-
LOCK button on the RKE transmitter, or turn the ignition
key to the ON position. If something has triggered the
system in your absence, the horn will sound three times
when you unlock the doors. Check the vehicle for tam-
pering.

pressing the LOCK/UNLOCK button on the key fob.
NOTE:
Pressing the LOCK button while you are inside
of the vehicle will activate the Security Alarm. Opening a
door with the Security Alarm activated will cause the
alarm to sound. Press the UNLOCK button to deactivate
the Security Alarm.
5. If the desired programming was not achieved or to
reactivate this feature, repeat the above steps.
To Lock the Doors and Swing Gate
Press and release the LOCK button on the key fob to lock
all doors. The turn signals will flash and the horn will

80 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The Basics of Off-Road Driving
You will encounter many types of terrain driving off-
road. You should be familiar with the terrain and area
before proceeding. There are many types of surface
conditions: hard packed dirt, gravel, rocks, grass, sand,
mud, snow and ice. Every surface has a different effect on
your vehicle’s steering, handling and traction. Control-
ling your vehicle is one of the keys to successful off-road
driving, so always keep a firm grip on the steering wheel
and maintain a good driving posture. Avoid sudden
accelerations, turns or braking. In most cases there are no
road signs, posted speed limits or signal lights. Therefore
you will need to use your own good judgment on what is
safe and what isn’t. When on a trail you should always be
looking ahead for surface obstacles and changes in
terrain. The key is to plan your future driving route while
remembering what you are currently driving over.

inflation pressure of each tire on your vehicle, and inflate
each tire to the vehicle’s recommended cold placard
pressure value. The system will automatically update
and the Tire Pressure Monitoring Telltale Light will
extinguish once the updated tire pressures have been
received. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation.
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and will remain on solid when a
system fault is detected. The system fault will also sound
a chime. If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. A system
fault can occur by any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
If your vehicle is equipped with a matching
full-size spare wheel and tire assembly, it has a tire
pressure monitoring sensor, and can be monitored by the
Tire Pressure Monitoring System (TPMS). In the event
that the matching full-size spare tire is swapped with a
low pressure road tire, the next ignition key cycle will
still show the Tire Pressure Monitoring Telltale Light to
be ON, and a chime to sound. Driving the vehicle for up
to 10 minutes above 15 mph (25 km/h) will turn OFF the
Tire Pressure Monitoring Telltale Light as long as none of
the road tires are below the low pressure warning thresh-
old.
334 STARTING AND OPERATING

HAZARD WARNING FLASHERS
Your vehicle’s hazard warning flasher is an emergency
warning system. When you activate it, all front and rear
directional signals will flash intermittently. Use it when
your vehicle is disabled on or near the road. It warns
other drivers to steer clear of you and your vehicle. This
is an emergency warning system, not to be used when the
vehicle is in motion.
To activate the warning flashers, press the switch on the
lower switch bank (below the climate controls). To turn
the warning flashers off, press the switch again.NOTE:With extended use, the flasher may wear down
your battery.
