Passenger Airbag Status Indicator
The vehicle has the passenger sensing system.
SeePassenger Sensing System on page 1-59for
important safety information. The instrument panel
has a passenger airbag status indicator.
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.
If you are using remote start to start the vehicle from a
distance, if equipped, you may not see the 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 inate).
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/retailer for service.
{CAUTION:
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

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
both parts need to be working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briey when the engine is
started. If it does not come on then, have it xed so
it will be ready to warn if there is a problem.
When the ignition is on, the brake system warning
light also comes on when the parking brake is set.
The light stays on if the parking brake does not fully
release. If it stays on after the parking brake is fully
released, it means the vehicle has a brake problem.If the light comes on while driving, pull off the road
and stop carefully. Make sure the parking brake is fully
released. The pedal might be harder to push or, the pedal
could go closer to the oor. It can take longer to stop.

comes on briey when
the engine is started.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally
the indicator light goes off.
If this light is on while certain DIC messages display,
this indicates that the ESC and TCS are not working
or are disabled.
If this light is on and not ashing, the TCS and
potentially the ESC system have been disabled. Check
the DIC messaging to determine which feature(s) is
no longer functioning and whether it is because of the
driver turning off the feature(s), or because the system is
not working properly and the vehicle requires service.

for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.
3-33

If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of the vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 5-3.This light comes on during a malfunction in one of
two ways:
Light Flashing:A misre condition has been detected.
A misre increases vehicle emissions and could damage
the emission control system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still ashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.
Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.

Fuel Gage
The fuel gage indicates
how much fuel the vehicle
has left.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.Here are four things that some owners ask about.
None of these show a problem with the fuel gage:At the service station, the gas pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took
a little more or less than half the tank’s capacity
to ll the tank.
The gage moves a little while turning a corner or
speeding up.
The gage does not go back to empty when the
ignition is turned off.
For the fuel tank capacity, seeCapacities and
Specifications on page 5-108.
