2009 JEEP GRAND CHEROKEE warning light

Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•Airbag Warning Light does not come on during the six
to eight seconds after the ignition switch is first turned
on,
•Remains on after the six to eight second interval, or
•Flickers, or comes on and remains on for any period of
time while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check the fuseblock for blown fuses. Refer to “Fuses” in Section 7 of this
manual. See your authorized dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see the following list) in an event data recorder
prior to the moment of airbag deployment, or near
deployment, and up to one-quarter second of high-speed
deceleration data during and/or after airbag deployment
or near-deployment. EDR data are ONLY recorded if an
airbag deploys, or nearly deploys, and are otherwise
unavailable.
NOTE:
•A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.

The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first

rized dealer.

the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is

patterns. Check for stones, nails, glass, or other objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.

CAUTION!
To avoid damage to the mirror during cleaning, never
spray any cleaning solution directly onto the mirror.
Apply the solution onto a clean cloth and wipe the
mirror clean.
Outside Mirrors
To receive maximum benefit, adjust the outside mirrors
to center on the adjacent lane of traffic with a slight
overlap of the view obtained on the inside mirror.
WARNING!
Vehicles and other objects seen in the passenger side
convex mirror will look smaller and farther away
than they really are. Relying too much on your
passenger side convex mirror could cause you to
collide with another vehicle or other object. Use your
inside mirror when judging the size or distance of a
vehicle seen in the passenger side convex mirror.
Some vehicles will not have a convex passenger side
mirror.

heated seat surfaces coming in contact with each
other and potential seat overheating, ALWAYS
ensure that the seat heater is in the Off position
(amber lights indicate High/Low/Off) before plac-
ing any of the seats into a folded flat position (if
equipped).

When the High-level setting is selected, the heater will
provide a boosted heat level during the first four minutes
of operation. Then, the heat output will drop to the
normal High-level. If the High-level setting is selected,
the system will automatically switch to Low-level after
approximately 30 minutes of continuous operation. At
that time, the number of illuminated LEDs changes from
two to one, indicating the change. The Low-level setting
will turn Off automatically after approximately 30 min-
utes.
NOTE:Once a heat setting is selected, heat will be felt
within two to five minutes.WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, ex-
haustion or other physical condition must exercise
care when using the seat heater. It may cause burns
even at Low temperatures, especially if used for
long periods of time.
•Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This
may cause the seat heater to overheat. To avoid
heated seat surfaces coming in contact with each
other and potential seat overheating, always en-
sure that the seat heater is in the Off position
(amber lights indicate High/Low/Off) before plac-
ing any of the seats into a folded flat position (if
equipped).
