To place the entire system in automatic mode, do
the following:
1. Press the driver’s temperature knob to turn
the system on.
2. Adjust the temperature to a comfortable
setting.
Choosing the coldest or warmest temperature
will not cause the system to heat or cool
any faster.
In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air
into your vehicle until warmer air is available.
Then, as the air warms, it will be delivered
through the instrument panel outlets. The
length of time needed for warm up will depend
on the outside temperature and the length
of time that has elapsed since your vehicle was
last driven.3. Adjust the PASS TEMP indicator that is
located below the temperature display. If
only the larger center bar is lit, the passenger
side will be adjust to the same temperature
setting as the driver side. Each bar that is lit to
the + side of the center bar indicates that
the passenger side will control to a warmer
setting than the driver side. Each bar lit to
the — side of the center bar indicates that the
passenger side will control to a cooler
setting than the driver side.
4. Wait for the system to regulate. This may take
from 10 to 30 minutes. Then adjust the
temperature as necessary.
5. To turn the system off, press the
passenger’s knob.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll
know how fast you’re going, how much fuel you’re using, and many other things you’ll need to drive
safely and economically. The indicator warning lights and gages are explained on the following pages.

Safety Belt Reminder Light
When the key is turned to ON 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 the safety belt light will be repeated. You
should buckle your safety belt. If the driver’s belt
is already 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 light tells you if there
is an electrical problem. The system check
includes the airbag sensor, the airbag modules,
the wiring, diagnostic module, and safety belt
pretensioners. For more information on the airbag
system, seeAirbag System on page 88. For
more information on safety belt pretensioners, see
Safety Belt Pretensioners on page 56.

Your vehicle may have a Traction Control System
(TCS) warning light. The TCS warning light
may come on for the following reasons:
If you turn the TCS off by pressing the TRAC
OFF button located in the instrument panel
switchbank the TCS warning light will come on
and stay on. To turn the system back on,
press the button again. The TCS warning light
should go off. SeeTraction Control System
(TCS) on page 310for more information.
If there is an engine-related and brake system
problem that is speci cally related to traction
control, the TCS will turn off and the TCS
warning light will come on.
If the TCS 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 Gage
This gage shows the engine coolant temperature.
If the gage pointer moves near the “H”, 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 378.

This can happen if you have recently replaced your
battery or if your battery has run down. The
diagnostic system is designed to evaluate critical
emission control systems during normal driving.
This may take several days of routine driving. If you
have done this and your vehicle still does not pass
the inspection for lack of OBD system readiness,
your dealer can prepare the vehicle for inspection.
Fuel Gage
When the indicator nears empty, you still have a
little fuel left, but you should get more soon.If your fuel is low, the warning message in the
message center will come on. SeeLow Fuel
Warning Message on page 232.
Your fuel gage tells you about how much fuel you
have left when the ignition is on.
Here are four things that some owners ask about.
All these things are normal and do not indicate
that anything is wrong with the fuel gage.
At the gas station, the gas pump shuts off
before the gage reads full.
It takes a little more (or less) fuel to ll up
than the gage reads. For example, the
gage reads half full, but it took more (or less)
than half of the tank’s capacity to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate empty when the
ignition is turned off.
Message Center
The message center is located at the top of the
instrument panel cluster in between the tachometer
and speedometer. It gives you important safety
and maintenance facts.

vehicle’s high-beam headlamp bulbs needs
replacement. SeeBulb Replacement on page 399
for more information.
Driver Information Center (DIC)
If your vehicle has a Driver Information Center
(DIC), the display is located on the instrument
panel cluster in the tachometer gage. The DIC will
show information about the vehicle and the
surroundings.The DIC is capable of displaying English or
French. To change the language, press and hold
