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 17 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.
It should go out when the engine is
started.
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 Centre (DIC) also
displays a message.
See Battery Voltage and Charging
Messages on page 5 32.
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.
