2009 JEEP WRANGLER inflation

CAUTION!
Do not press on rear wiper blade when closing the
rear flip-up window, as damage to the blade will
result.
WARNING!
Driving with the flip-up window open can allow
poisonous exhaust gases into your vehicle. You and
your passengers could be injured by these fumes.
Keep the flip-up window closed when you are oper-
ating the vehicle.
OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems. These include the front
and rear seat belts for the driver and all passengers,
Advanced Front Airbags for both the driver and front
passenger, and side airbags (if equipped) for both the
driver and front passenger. If you will be carrying
children too small for adult-sized belts, your seat belts
can also be used to hold infant and child restraint
systems.
NOTE:The Advanced Front Airbags have a multistage
inflator design. This allows the airbag to have different
rates of inflation that are based on collision severity.
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly, to keep you and your passengers as safe as
possible.
38 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:These airbags are certified to the new Federal
regulations for Advanced Airbags.
The Advanced Front Airbags have a multistage inflator
design. This allows the airbag to have different rates of
inflation that are based on the severity and type of
collision.
1 — Driver Airbag
2 — Passenger Airbag
3 — Knee Bolster

WARNING! (Continued)
•If your vehicle is equipped with side airbags, do not
attach cupholders or any other objects on or around
the door. The inflating side airbag could drive the
objects into occupants, causing serious injury.
•Do not cover or place items on the airbag covers.
These items may cause serious injury during infla-
tion.
•Do not store or place items under the front seats.
You may damage the airbag wiring harnesses.
The Advanced Front Airbags have a multistage inflator
design. This allows the airbag to have different rates of
inflation that are based on severity and type of collision.
Along with the seat belts, Advanced Front Airbags work
with the instrument panel knee bolsters to provide
improved protection for the driver and front passenger.
Side airbags also work with seat belts to improve occu-
pant protection.Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag:
1. Children 12 years and under should always ride
buckled up in a rear seat.
Infants in rear facing child restraints should
NEVERride
in the front seat of a vehicle with a passenger airbag. An
airbag deployment could cause severe injury or death to
infants in that position.
Children that are not big enough to properly wear the
vehicle seat belt should be secured in the rear seat, in a
child restraint or belt-positioning booster seat. Older
children who do not use child restraints or belt-
positioning booster seats should ride properly buckled
up in the rear seat. Never allow children to slide the
shoulder belt behind them or under their arm.

WARNING!
Ignoring the Airbag Warning Light in your instru-
ment panel could mean you won’t have the airbags to
protect you in a collision. If the light does not come
on, stays on after you start the vehicle, or if it comes
on as you drive, have the airbag system checked
immediately.
•TheDriver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator
units. A large quantity of non-toxic gas is generated to
inflate the Advanced Front Airbags. Different airbag
inflation rates are possible, based on 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 bags inflate to their full size. The bags fully inflate in about 50 to 70 millisec-
onds. This is about half of the time it takes to blink
your eyes. The bags then quickly deflate while helping
to restrain the driver and front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides
of the airbag. In this way, the airbags do not interfere
with your control of the vehicle.
•The
Side Impact (SRS) Seat-Mounted Side Airbags
(If Equipped) are designed to activate only in certain
side collisions.
The ORC determines if a side collision requires the
side airbags to inflate based on the severity and type of
collision.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

•As the airbags deflate you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for
airbag inflation. These airborne particles may irritate
the skin, eyes, nose, or throat. If you have skin or eye
irritation, rinse the area with cool water. For nose or
throat irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles settle on
your clothing, follow the garment manufacturer’s in-
structions for cleaning.
•Do not drive your vehicle after the airbags have
deployed. If you are involved in another collision, the
airbags will not be in place to protect you.
WARNING!
Deployed airbags and seat belt pretensioners cannot
protect you in another collision. Have the airbags,
seat belt pretensioner, and seat belt retractor assem-
bly replaced by an authorized dealer as soon as
possible.
Enhanced Accident Response System
In the event of an impact causing airbag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of the
event the ORC will determine whether to have the
Enhanced Accident Response System to perform the
following functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.

21. Odometer / Trip Odometer Reset Button
Press this button to change the display from odometer to
either of the two trip odometer settings. Trip A or Trip B
will appear when in the trip odometer mode. Press and
hold the button for two seconds to reset the trip odometer
to 0 miles or kilometers. The odometer must be in trip
mode to reset.
22. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
23. Tire Pressure Monitoring Telltale LightEach tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.

computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated to produce
accurate signals for the computer.
WARNING!
Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The Anti-Lock Brake System conducts a low speed self-
test at about 12 mph (20 km/h). If for any reason your
foot is on the brake when the vehicle reaches 12 mph
(20 km/h), this check will be delayed until 25 mph
(40 km/h). The Anti-Lock Brake System pump motor runs during
the self-test, and during an ABS stop, to provide the
regulated hydraulic pressure. The motor pump makes a
low humming noise during operation; this is normal.
During off-road use, loss of traction can temporarily
defeat the system and cause the warning light to illumi-
nate. Turn the ignition to LOCK and ON again to restore
Anti-Lock Brake System function.WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.
