Ashtrays
For vehicles with a removable
ashtray, it can be placed into the
cupholder and be removed for
cleaning.
Notice:If papers, pins, or other
flammable items are put in the
ashtray, hot cigarettes or other
smoking materials could ignite
them and possibly damage the
vehicle. Never put flammable
items in the ashtray.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working. Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

5-10 Instruments and Controls
The front passenger safety belt
warning light and chime may turn on
if an object is put on the seat such
as a briefcase, handbag, grocery
bag, laptop or other electronic
device. To turn off the warning light
and or chime, remove the object
from the seat or buckle the
safety belt.
Airbag Readiness Light
There is an airbag readiness light
on the instrument panel cluster,
which shows the airbag symbol.
The system checks the airbag's
electrical system for malfunctions.
The light indicates if there is an
electrical problem. The system
check includes the airbag sensor,
the pretensioners, the airbagmodules, the wiring and the crash
sensing and diagnostic module.
For more information on the airbag
system, see
Airbag System
on
page 3‑27.
This light comes on when the
vehicle is started, and flashes for a
few seconds. The light goes out
when the system is ready.
If the airbag readiness light stays on
after the vehicle is started or comes
on while driving, the airbag system
may not work properly. Have the
vehicle serviced right away.
{WARNING
If the airbag readiness light
stays on after the vehicle is
started or comes on while driving,
it means the airbag system
might not be working properly.
The airbags in the vehicle might
not inflate in a crash, or they
could even inflate without a crash.
To help avoid injury, have the
vehicle serviced right away.
The airbag readiness light should
flash for a few seconds when the
engine is started. If the light does
not come on then, have it fixed
immediately.

Instruments and Controls 5-11
Passenger Airbag Status
Indicator
The vehicle has the passenger
sensing system. SeePassenger
Sensing System
on page 3‑35for
important safety information. The
instrument panel has a passenger
airbag status indicator.
United States
Canada
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds as a system check. Then, after
several more seconds, the status
indicator will light either ON or OFF,
or either the on or off symbol to let
you know the status of the right front
passenger frontal airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the right
front passenger frontal airbag is
enabled (may inflate).
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the right front
passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be
a problem with the lights or the
passenger sensing system. See
your dealer for service.
{WARNING
If the airbag readiness light
ever comes on and stays on, it
means that something may be
wrong with the airbag system.
To help avoid injury to yourself or
others, have the vehicle serviced
right away. See
Airbag Readiness
Light
on page 5‑10for more
information, including important
safety information.
Charging System Light
This light comes on briefly when the
ignition key is turned, but the engine
is not running, as a check to show it
is working.

5-14 Instruments and Controls
Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection
could prevent getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
.The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in
ON/RUN and the light is not on.
.The vehicle will not pass
this inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would
be considered not ready for
inspection. This can happen ifthe battery has recently been
replaced or if the battery has run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.
Brake System Warning
Light
The vehicle's hydraulic brake
system is divided into two parts.
If one part is not working, the other
part can still work and stop the
vehicle. For good braking though,
both parts need to be working well.
If the warning light comes on, there
could be a brake problem. Have the
brake system inspected right away.
United StatesCanada
This light comes on briefly when the
ignition key is turned to ON/RUN.
If it does not, have it fixed so it will
be ready to warn if there is a
problem.
When the ignition is on, the brake
system warning light comes on
when the parking brake is set.
See Parking Brake
on page 9‑51for more information. The light stays
on if the parking brake does not
release fully. If it stays on after the
parking brake is fully released, it
means there is a brake problem.

Instruments and Controls 5-15
If the light comes on while driving,
pull off the road and stop. The brake
pedal might be harder to push, or it
might go closer to the floor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing the Vehicle
on
page 10‑90.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light will then go off.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes. If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light
on page 5‑14.
For vehicles with a Driver
Information Center (DIC), see
Brake System Messages
on
page 5‑22for more information.
