;(Parking Lamp):Turn the band to this position to
turn on the parking lamps together with the following:
Taillamps
License Plate Lamps
Instrument Panel Lights
The parking brake indicator light comes on and stays
on when the parking lamps are on with the engine
in LOCK/OFF and the ignition to ACC/ACCESSORY.
5(Headlamps):Turn the control to this position
to turn on the headlamps together with the following
lamps listed below. A warning chime sounds if the

Instrument Panel Lights
Headlamps on Reminder
A warning chime will sound if the vehicle’s ignition is
off and the driver’s door is opened when the exterior
lamp control is left on in either the headlamp or
parking lamp position.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Daytime running
lamps are required to function at all times on all
vehicles rst sold in Canada.
A light sensor on top of the instrument panel makes
the DRL work, so be sure it is not covered.
The DRL system will make the low-beam headlamps
come on at reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness. The turn
signal, taillamps, sidemarker and other lamps will not be
on. The instrument panel cluster will not be lit up either.

When the ignition key is turned to ON/RUN, the HUD
will display an introductory message for a short
time, until the HUD has warmed up.
The following indicator lights come on the instrument
panel when activated and will also appear on the HUD:
Turn Signal Indicators
High-Beam Indicator Symbol
The HUD will temporarily display CHECK TRIP
COMPUTER when there are messages on the
DIC trip computer.
The HUD will also display the following messages when
these systems, if the vehicle has them, are active:
TRACTION CONTROL ACTIVE
STABILITY CONTROL ACTIVE
The HUD will temporarily display the TRACTION
CONTROL OFF message when the traction control
system is turned off.
The HUD will temporarily display the CRUISE SET
message when cruise control is activated or cruise
speed is increased.
Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance and
damage your vehicle. Do not use the HUD image
as a parking aid.When the HUD is on, the speedometer reading will
continually be displayed. The current radio station or
CD track number will display for a short period of time
after the radio or CD track status changes. This will
happen whenever one of the radio controls is pressed.

CD information, warnings, or turn-by-turn guidance
information are displayed on the HUD.
The HUD control is
located on the console.
To adjust the HUD image so that items are properly
displayed, do the following:
1. Adjust the driver’s seat to a comfortable position.
2. Start the engine.
3. Adjust the HUD controls.

Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages on
your vehicle. The pictures help to 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 the 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 the
details show on the next few pages, some warning lights
come on briey when you start the engine just to let
you know they are 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 is a problem with your vehicle.
When one of the warning lights comes on and stays on
as 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 vehicle’s
warning lights and gages. They can be a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 3-55for more information.

Instrument Panel Cluster
The instrument panel cluster is designed to show at a glance how the vehicle is running. It will show how fast the
vehicle is going, about how much fuel is in the fuel tank, and many other things needed to drive the vehicle safely
and economically.
The vehicle is equipped with this cluster or one very similar to it. It has indicator warning lights that are explained
on the following pages. Be sure to read about them.United States version shown, Canada similar
3-39

Driver Information Center (DIC)
The Driver Information Center (DIC) gives important
safety and maintenance facts. When the vehicle’s
ignition is turned on, all of the DIC lights illuminate for a
few seconds and an introductory message will appear.
After this, the DIC will begin working.
DIC Operation and Displays
(Uplevel DIC with Trip Computer)
The Driver Information Center (DIC) control buttons and
the message display screen are located above the
radio. The DIC gives important safety and maintenance
facts concerning the vehicle. The status of many of
the vehicle’s systems along with driver personalization
menus and warning messages about the vehicle’s
systems may display on the DIC screen.
The outside temperature automatically appears on
the bottom right corner of the DIC display screen.
If the outside temperature is below 38°F (3°C), the
temperature reading will toggle between displaying the
outside temperature and the word ICE for two minutes.
If there is a problem with the system that controls
the temperature display, the letters OC (Open Circuit)
or SC (Short Circuit) will appear on the display.
If this occurs, have the vehicle serviced by your
dealer/retailer.The vehicle’s shift lever position and the direction the
vehicle is traveling will also appear on the DIC screen.
The compass is self-calibrating, which eliminates
the need to manually set the compass. However, under
certain circumstances, such as during a long distance
cross-country trip, it will be necessary to compensate
for compass variance and reset the zone through
the DIC. SeeDIC Compass (Uplevel DIC) on page 3-65
for more information.
The buttons on the DIC trip computer are gages,
trip odometer, set/reset, options, and fuel.

REMAINING, TRANSMISSION FLUID TEMPERATURE,
BATTERY, ENGINE HOURS, and MAXIMUM Gs modes.

The vehicle has bulb warning lights. When a trailer
lighting system is plugged into the vehicle’s lighting
system, its bulb warning lights may not indicate if one of
the lamps goes out. So, when a trailer lighting system
is plugged in, be sure to check the vehicle and
trailer lamps from time to time to be sure they are all
working. Once the trailer lamps have been disconnected,
the bulb warning lights can once again indicate if one
of the vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gear before starting
down a long or steep downgrade. If the vehicle is
not shifted down, the brakes may have to be used so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of engine and transmission overheating.
If the vehicle has overdrive, it may be driven in
THIRD (3) instead of DRIVE (D).
Parking on Hills
{CAUTION:
You really should not park your vehicle, with
a trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if the rig ever has to be parked on a hill, here is
how to do it:
1. Apply the regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply the
parking brake, and then shift to PARK (P).
5. Release the regular brakes.

If the uid level is low, add only enough of the proper
uid to bring the level into the crosshatched area on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at the
dipstick hole to bring it to the proper level.
It does not take much uid, generally less than one
pint (0.5 L). Do not overll.
Notice:Use of the incorrect automatic transmission
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always use
the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 6-12.
3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
4. When the correct uid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if only
DEX-COOL
®extended life coolant is added.The following explains the cooling system and how to
add coolant when it is low. If there is a problem with
engine overheating or if coolant needs to be added to the
radiator, seeEngine Overheating on page 5-27.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®engine coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
