The airbag readiness light comes
on solid and stays on for several
seconds when the vehicle is started.
Then the light goes out.
If it stays on solid after the vehicle
has been 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.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. SeePassenger
Sensing System on page 3‑37
for important safety information.
The instrument panel has a
passenger airbag status indicator.
When the vehicle is started, the
passenger airbag status indicator
will light the words ON and OFF for
several seconds as a system check.

If you are using remote start,
if equipped, to start the vehicle
from a distance, you may not see
the system check. Then, after
several more seconds, the status
indicator will light either the word
ON or OFF to let you know the
status of the right front passenger
frontal airbag.
If the word ON 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 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 5‑14 for more
information, including important
safety information.
Charging System Light
The charging system light comes
on briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is
on could drain the battery.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.

Emissions Inspection and
Maintenance Programs
Some state/provincial and
local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is connected
to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
.The critical emission control
systems have not been
completely diagnosed by
the system. This can happen
if the battery has recently
been replaced or if the battery
has run down. The diagnostic
system evaluates 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, your dealer can
prepare the vehicle for
inspection.
Brake System Warning
Light
The vehicle brake system
consists of two hydraulic circuits.
If one circuit is not working, the
remaining circuit can still work to
stop the vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have your brake
system inspected right away.
EnglishMetric
If the vehicle has antilock brakes,
this light should come on when the
vehicle is placed in START. If it does
not, have the vehicle serviced by
your dealer.

the road and carefully stopped,
have the vehicle towed for
service.
Electric Parking Brake
Light
EnglishMetric
For vehicles with the Electric
Parking Brake (EPB), the parking
brake status light comes on
when the brake is applied. If the

If this light comes on, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be driven,
but should be taken to a dealer
as soon as possible. See Parking
Brake on page 9‑33 for more
information.
