ashtray located near the center of
the instrument panel. Pull on the
door to open it. The ashtray may
have a cigarette lighter.
Notice:If papers, pins, or other
flammable items are put in the
ashtray, hot cigarettes or other
smoking materials could ignite

vehicle. Never put flammable
items in the ashtray.
To remove the ashtray, open the

Warning Lights,
Gauges, and
Indicators
Warning lights and gauges 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 gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working. Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges 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 gauges
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.

{WARNING
If the right front passenger airbag
is turned off for a person who is
not in a risk group identified by
the national government, that
person will not have the extra
protection of an airbag. In a
crash, the airbag will not be able
to inflate and help protect the
person sitting there.
Do not turn off the passenger
airbag unless the person sitting
there is in a risk group identified
by the national government. See
Airbag On-Off Switch on
page 3‑28for more on this,
including important safety
information.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. For
example, the right front
passenger airbag could inflate
even though the airbag on-off
switch is turned off.
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.
If the word ON or the on symbol is
lit, it means that the right front
passenger frontal airbag is enabled
(may inflate). See Airbag On-Off
Switch on page 3‑28 for more
information, including important
safety information. 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 airbag
on-off switch. See your dealer for
service.
Passenger Airbag Status
Indicator
If the vehicle has one of the
indicators pictured in the following
illustrations, then the vehicle has a
passenger sensing system for the
right front passenger position unless
there is an airbag off switch located
in the glove box. If there is an
airbag off switch, the vehicle does
not have a passenger sensing
system. See
Airbag On-Off Switch
on page 3‑28.
The passenger airbag status
indicator is on the overhead
console. See Passenger Sensing
System on page 3‑31 for important
safety information.

In addition, if the vehicle has a
passenger sensing system for the
right front passenger position, the
label on the vehicle's sun visor
refers to“ADVANCED AIRBAGS”.
United States

When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds
as a 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 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 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.
