Instruments and Controls 109
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag is
allowed to 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 front
outboard 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. SeeAirbag Readiness
Light 0108 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 may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays a message.
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.
Malfunction
Indicator Lamp
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is in
Service Mode. See Ignition
Positions 0175.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.

The DLC is under the instrument
panel to the left of the steering
wheel. Connecting devices that are
not used to perform an Emissions
Inspection/Maintenance test or to
service the vehicle may affect
vehicle operation. SeeAdd-On
Electrical Equipment 0210. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine
is running.
. The light does not come on
when the ignition is in
Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.
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 the brake
system inspected right away.
MetricEnglish This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is
a problem.
If the light comes on and stays on,
there is a base brake problem.
{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.

136 Lighting
Exterior Lamps Off
Reminder
A warning chime will sound if the
exterior lamp control is left on in
either the headlamp or parking lamp
position and the driver door is
opened with the ignition off.
Headlamp High/
Low-Beam Changer
Push the turn signal lever away
from you and release to turn the
high beams on. To return to low
beams, push the lever again or pull
it toward you and release.
This indicator light turns on in the
instrument cluster when the
high-beam headlamps are on.
Flash-to-Pass
To use the flash-to-pass feature,
briefly pull the turn signal lever
toward you. The high-beam
indicator flashes to indicate to the
other driver that you intend to pass.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day. DRL are required on all
vehicles first sold in Canada.
The DRL system makes the
dedicated lamps come on when the
following conditions are met:
.It is still daylight and the ignition
is on.
. The exterior lamp control is in
the AUTO position.
. The transmission is not in
P (Park) or the parking brake
is off.
When DRL are on, only the front
lamps will be on. The parking
lamps, taillamps, instrument panel lights, or other exterior lamps will
not be on when the DRL are
being used.
When it is dark enough outside, the
front lamps dim to parking lamps
and the normal low-beam
headlamps turn on.
When it is bright enough outside,
the regular lamps go off, and the
front DRL will take over. If the
vehicle is started in a dark garage,
the automatic headlamp system
comes on immediately. Once the
vehicle leaves the garage, it takes
approximately one minute for the
automatic headlamp system to
change to DRL if it is light outside.
During that delay, the instrument
cluster may not be as bright as
usual. Make sure the instrument
panel brightness knob is in the full
bright position. See
Instrument
Panel Illumination Control 0139.
If it is dark enough outside and the
exterior lamp control is off, a Driver
Information Center (DIC) message
may display.
