Warning Lights,
Gages, and Indicators
Warning lights and gages 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 gages could
prevent injury.
Warning lights come on when
there may be or is a problem with
one of the vehicle’s functions.
Some warning lights come on brie y
when the engine is started to indicate
they are working.Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages 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 gages 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.
4-10 Instruments and Controls

Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. SeePassenger
Sensing System on page 1-27
for important safety information.
The rearview mirror 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 secondsas a system check. If you are using
remote start to start your 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 in ate).
If the word OFF or the off symbol is
lit on the passenger 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.

serviced right away. If both brake
lights are on, you do not have
antilock brakes, and there’s a
problem with your regular brakes as
well. Have your vehicle towed for
service. SeeTowing Your Vehicle
on page 9-88.
The ABS Fault message will remain

and stays on on steady for the
remainder of the ignition cycle.
This sequence will repeat with every
ignition cycle. SeeTire Pressure
Monitor System on page 9-52
