2013 JEEP WRANGLER UNLIMITED turn signal bulb

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.
NOTE: The Key-In-Ignition reminder only sounds when
the ignition key is placed in the LOCK or ACC position.
SENTRY KEY 
The Sentry Key  Immobilizer System prevents unauthor-
ized 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 ve-
hicle operation. Therefore, only keys that are programmed
to the vehicle can be used to start and operate the vehicle.
The system will shut the engine off in two seconds if
someone uses an invalid key to try to start the engine. NOTE: A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on after the
bulb check, it indicates that there is a problem with the
electronics. In addition, if the Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key to try to start the engine.
Either of these conditions will result in the engine being
shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.
Driver And Passenger Advanced Front Air Bag
Inflator Units
The Driver and Passenger Advanced Front Air Bag
Inflator Units are located in the center of the steering
wheel and on the right side of the instrument panel. When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag inflation rates
are possible, based on several factors, including the
collision type and severity. The steering wheel hub trim
cover and the upper right side of the instrument panel
separate and fold out of the way as the air bags inflate to
their full size. The air bags fully inflate in about 50 to
70 milliseconds. This is about half of the time it takes to
blink your eyes. The air bags then quickly deflate while
helping to restrain the driver and front passenger.
The Advanced Front Air Bag gas is vented through the
vent holes in the sides of the air bag. In this way, the air
bags do not interfere with your control of the vehicle. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

Turn Signals
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster flash to show
proper operation of the front and rear turn signal lights. NOTE:
• If either light remains on and does not flash, or there is
a very fast flash rate, check for a defective outside light
bulb. If an indicator fails to light when the lever is
moved, it would suggest that the indicator bulb is
defective.
• A tone will chime if the turn signals are left on for more
than 1 mile (2 km).
Lane Change Assist
Tap the lever up or down once, without moving beyond
the detent, and the turn signal (right or left) will flash
three times then automatically turn off.
Turn Signal Operation

7. Seat Belt Reminder Light
When the ignition switch is first turned to ON/
RUN, this light will turn on for four to eight
seconds as a bulb check. During the bulb check, if
the driver’s seat belt is unbuckled, a chime will sound.
After the bulb check or when driving, if the driver seat
belt remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
8. Turn Signal Indicators
The left or right arrow will flash with the corre-
sponding exterior turn signal lights when the turn
signal lever is operated. A chime will sound if the vehicle is
driven more than 1 mile (1.6 km) with either turn signal on.
NOTE: If either indicator flashes at a rapid rate, check
for a defective outside light bulb. 9. Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started; if the bulb does not come on, have the system
checked by an authorized dealer. If the light turns on while
driving, stop the vehicle and shut off the engine as soon as
possible. A chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
10. High Beam Indicator
This indicator shows that the high beam head-
lights are on. Push the multifunction control lever
away from you to switch the headlights to high beam.
Pull the lever toward you to switch the headlights back to
low beam. If the driver’s door is open, and the headlights
or park lights are left on, the high beam indicator light
will remain illuminated and a chime will sound. 4 UNDERSTANDING YOUR INSTRUMENT PANEL 301

BULB REPLACEMENT

spheric conditions. This will usually clear as atmospheric
conditions change to allow the condensation to change
back into a vapor. Turning the lamps on will usually
accelerate the clearing process.
