Outside Power Heated Mirrors
For information on the operation of the outside power
mirrors seeOutside Power Mirrors on page 2-37.
If the vehicle has heated mirrors, they will warm up to
melt ice and snow, and dissolve condensation when the
defroster is turned on. SeeDual Automatic Climate
Control System on page 3-25orClimate Control System
on page 3-22.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be seen from
the driver’s seat, but it also makes things look farther
away than they really are.

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety belt.
This would only occur if the passenger airbag is enabled.
SeePassenger Sensing System on page 1-65for more
information. The passenger safety belt light will also
come on and stay on for several seconds, then it will
ash for several more.
If the passenger’s safety
belt is buckled, neither
the chime nor the light
will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The system check includes the airbag modules, the
wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 1-56.
This light will come on
when the vehicle is
started, and it will ash
for a few seconds. Then
the light should go out.
This means the system
is functioning properly.
If the airbag readiness light stays on after the vehicle
is started, or comes on as the vehicle is being driven,
there may be an electrical problem and the airbag
system may not work properly. Have the vehicle serviced
right away.
3-34

{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should ash for a few seconds
when you turn the ignition key to RUN. If the light does
not come on then, have it xed so it will be ready to warn
you if there is a problem.
Passenger Airbag Status Indicator
Your instrument panel has a passenger airbag status
indicator. SeePassenger Sensing System on page 1-65
for more information.
When the ignition key is turned to RUN or START, the
passenger airbag status indicator will light ON and OFF
for several seconds as a system check. If you use 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 to let you know the status of the right front
passenger’s frontal airbag.Passenger Airbag
Status Indicator
3-35

If, after several seconds, all 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.
{CAUTION:
If the off indicator and the airbag readiness light
ever come on together, it means that something
may be wrong with the airbag system. If this
ever happens, have the vehicle serviced
promptly, because an adult-size person sitting
in the right front passenger seat may not have
the protection of the frontal airbag. SeeAirbag
Readiness Light on page 3-34.
Charging System Light
The charging system light
will come on briey when
the ignition is turned on,
as a check to show that it
is working. Then it should
go out.
If it stays on, or comes on while the vehicle is being
driven, a chime will sound and there may be a problem
with the charging system. It could indicate that the
vehicle has a loose accessory belt or another electrical
problem. Have it checked right away. Driving while
this light is on could drain the battery.
If the vehicle must be driven a short distance with the
light on, be certain to turn off all the accessories,
such as the radio and air conditioner.
