An arrow on the
instrument panel cluster
will ash in the
direction of the turn or
lane change.
As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb may be burned out and other drivers will not
see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
you signal a turn, check for burned-out bulbs and a
blown fuse. SeeFuses and Circuit Breakers on
page 600.Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each ash
of the turn signal and the message TURN SIGNAL
ON will also appear in the Driver Information
Control (DIC). To turn the chime and message off,
move the turn signal lever to the off position.
Headlamp High/Low-Beam Changer
53(Headlamp High/Low Beam
Changer):To change the headlamps from low to
high beam, push the lever toward the instrument
panel. To return to low-beam headlamps, pull
the multifunction lever toward you. Then release it.
When the high beams
are on, this indicator light
on the instrument panel
cluster will also be on.
215

Flash-to-Pass
This feature lets you use your high-beam
headlamps to signal a driver in front of you that
you want to pass. It works even if your headlamps
are in the automatic position.
To use it, pull the turn signal lever toward you,
then release it.
If your headlamps are in the automatic position or
on low beam, your high-beam headlamps will
turn on. They will stay on as long as you hold the
lever toward you. The high-beam indicator on
the instrument panel cluster will come on. Release
the lever to return to normal operation.
Windshield Wipers
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the
windshield, gently loosen or thaw them. Damaged
wiper blades may not clear the windshield well,
making it harder to see and drive safely. If the
blades do become damaged, install new blades or
blade inserts. For more information, seeWindshield
Wiper Blade Replacement on page 542.Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the band
to mist. Hold it there until the wipers start. Then let
go. The wipers will stop after one wipe. If you want
more wipe cycles, hold the band on mist longer.
6(Delay):You can set the wiper speed for a long
or short delay between wiping cycles. This can
be very useful in light rain or snow. Turn the band
to choose the delay time. The closer to the top
of the lever, the shorter the delay.
6(Low Speed):For steady wiping at low
speed, turn the band away from you to the
rst solid band past the delay settings.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.

The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the
daytime and nighttime operation of the Daytime
Running Lamps (DRL) and the automatic headlamp
systems so that driving under bridges or bright
overhead street lights does not affect the system.
The DRL and automatic headlamp system will only
be affected when the light sensor detects a change
in lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately one minute for the automatic
headlamp system to change to DRL if it is
bright enough outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 226.To idle your vehicle with the automatic headlamp
system off, turn the control to the off position.
You may be able to turn off your Automatic
Headlamp System. SeeDaytime Running Lamps
(DRL) on page 222for more information.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 282.
As with any vehicle, you should turn on the
regular headlamp system when needed.
224

Cargo Lamp
The cargo lamp button
is located on the left
side of the instrument
panel. Press the
button to turn the cargo
lamp on or off.
An indicator light on the instrument panel cluster
will come on when the cargo lamp is turned
on, and the ignition key is turned to RUN.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio. The outlet can accept
electrical equipment up to a maximum of
20 amperes.
Your vehicle may have two accessory power
outlets, or may have one accessory power outlet
located near the cigarette lighter, if the vehicle
has one. The cigarette lighter is designed to t only
in the receptacle to the right of the accessory
power outlet.
To use an outlet, remove the protective cap.
When not in use, always cover the outlet with the
protective cap. The accessory power outlet is
operational at all times.
Notice:If electrical devices are left plugged
into a power outlet, the battery may drain
causing your vehicle not to start or damage to
the battery. This would not be covered by
the warranty. Always unplug all electrical
devices when turning off your vehicle.
228

Instrument Panel Cluster
Your instrument cluster is designed to let you know at a glance how your vehicle is running. You will
know how fast you are going, about how much fuel you have and many other things you will need to know
to drive safely and economically.
United States Heavy Duty Automatic Transmission version shown. Canada, Light Duty Automatic and Manual
Transmission Clusters similar.

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).
Engine Hour Meter Display
The Driver Information Center (DIC) can also
display the number of hours the engine has run.
To display the hour meter, turn the ignition
off, press and hold the reset button for at least
four seconds. The hour meter will be displayed for
up to 30 seconds, or until the ignition is turned
on. SeeDIC Operation and Displays on page 266
for more information.
Trip Odometer
The trip odometer can tell you how far your
vehicle has been driven since you last set the trip
odometer to zero.
Press the reset button, located on the instrument
panel cluster next to the trip odometer display,
to toggle between the trip odometer and the
regular odometer. Holding the reset button for
approximately one second while the trip odometer
is displayed will reset it.
To display the odometer reading with the ignition
off, press the reset button.
SeeDIC Operation and Displays on page 266for
more information.

Safety Belt Reminder Light
When the key is turned to RUN or START, a
chime will sound for several seconds to remind
people to buckle their safety belts. The driver
safety belt light will also come on and stay on for
several seconds, then it will ash for several
more. You should buckle your seat belt.
This chime and light will
be repeated if the driver
remains unbuckled
and the vehicle
is in motion.
SeeDIC Warnings and Messages on page 270for
more information on driver and passenger
safety belt reminders.
If the driver’s belt is buckled, neither the chime nor
the light will come on.
SeePassenger Sensing System on page 103for
more information.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel cluster, 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 sensors, the airbag modules, the wiring and
the crash sensing and diagnostic module and, if
equipped, the passenger sensing system. For more
information on the airbag system, seeAirbag
System on page 91.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
This means the system
is ready.
If the airbag readiness light stays on after the
vehicle is started or comes on while you are
driving, the airbag system may not be working
properly. Have your vehicle serviced right away.

Here are some situations you may experience with
your fuel gage. None of these indicate a problem
with the fuel gage.
At the gas station, the fuel pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the fuel gage indicated. For example, the
gage may have indicated the tank was half full,
but it actually took a little more or less than
half the tank’s capacity to ll the tank.
The gage goes back to empty when you turn
off the ignition.
If you have a diesel engine, see “Fuel Gage” in
the Diesel Engine Supplement.
Low Fuel Warning Light
The light next to the fuel gage will come on briey
when you are starting the engine.
This light comes on when the fuel tank is low on
fuel. To turn it off, add fuel to the fuel tank.
SeeFuel on page 470.
Driver Information Center (DIC)
The Driver Information Center (DIC) display is
