help with fuel economy while still maintaining
the selected temperature.
On hot days, open the windows to let hot inside
air escape; then close them and switch to
maximum air conditioning mode. This helps to
reduce the time it takes for your vehicle to
cool down. It also helps the system to operate

from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.((Heated Seats):Press this button to turn on

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will
help you locate them.
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 your warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As
you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they’re
working. If you are familiar with this section,
you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let
you know when there’s a problem with your
vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Please follow this manual’s advice. Waiting to
do repairs can be costly — and even dangerous.
So please get to know your warning lights and
gages. They’re a big help.

Speedometer and Odometer
Your speedometer lets you see your speed in
both miles per hour (mph) and kilometers per
hour (km/h). Your odometer shows how far your
vehicle has been driven, in either miles (used
in the United States) or kilometers (used in
Canada).
Your vehicle has a tamper-resistant odometer.
You may wonder what happens if your vehicle
needs a new odometer installed. The new one can
be set to the mileage total of the old odometer.
Trip Odometer
The trip odometer can display how far you have
driven since you last reset it.
For more information seeDIC Operation and
Displays on page 249.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START, a
chime will come on for several seconds to remind
people to fasten their safety belts.
The safety belt light will
also come on and stay
on for several
seconds, then it will
ash for several more.
If the driver remains unbuckled when the ignition
is on and the vehicle is in motion, the chime
and safety belt light will be repeated. You should
buckle your seat belt. If the driver’s belt is
already buckled, neither the chime nor the light
will come on.
232

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’s airbag or airbags. See
Passenger Sensing System on page 106for more
on this, including important safety information.
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 an airbag. SeeAirbag
Readiness Light on page 234.
Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the
engine is not running,
as a check to show you
it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving,
you may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this
light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
237

{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
Your vehicle has an
Anti-lock Brake System
(ABS) warning light.
This light should come on 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.
If this light stays on longer than normal after you
have started your engine, turn the ignition off. If the
light comes on and stays on when you are
driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on
again while you are driving, the ABS needs service
and you do not have anti-lock brakes.
239

Traction Control System (TCS)
Warning Light
Your vehicle is equipped
with a traction control
system warning light.
The traction control system warning light may
come on for the following reasons:
If you turn the system off by pressing the
traction control button. To turn the system
back on, press the button again. The warning
light should go off. SeeTraction Control
System (TCS) on page 379for more
information.
If there’s a brake system problem that is
specically related to traction control, the
traction control system will turn off and
the warning light will come on. If your brakes
begin to overheat, the traction control
system will turn off and the warning light will
come on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the system will turn
off and the warning light will come on.
If the traction control system warning light comes
on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service.

Engine Coolant Temperature GageThis gage shows the engine coolant temperature.
If the red gage lamp turns on, your engine is
too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under
normal driving conditions, you should pull off the
road, stop your vehicle and turn off the engine
as soon as possible.
SeeEngine Overheating on page 451.
