Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers nd this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are four ways to turn off the cruise control:
Step lightly on the brake pedal,
move the cruise control switch to off, or
shift the transmission to NEUTRAL (N).
If your vehicle has the Stabilitrak®feature, cruise
control will turn off if road conditions cause
Stabilitrak
®to activate.
If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Headlamps
The control on the driver’s side of your instrument panel
operates the headlamps.
Turn the control clockwise to operate the lamps.
The headlamp control has four positions:
9(Off):Turning the control to this position turns off
the Daytime Running Lamps (DRL) and the automatic
headlamps.
AUTO (Automatic):Turning the control to this position
puts the system into automatic headlamp mode.
3-13

;(Parking Lamps):Turning the control to this
position turns on the parking lamps, together with the
following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
Roof Marker Lamps (If Equipped)
5(Headlamps):Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
You can switch your headlamps from high to low-beam
by pushing the turn signal/high-beam lever towards
the instrument panel.
A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will icker on and
off. Have your headlamp wiring checked right away if
this happens.
Headlamps on Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your
ignition is off, in LOCK, ACCESSORY, or your door is
open. To disable the chime, turn the light off then
back on.
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. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on
The exterior lamps control is AUTO
The automatic transmission is not in PARK (P)
The light sensor determines it is daytime
When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
3-14

When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
When you turn the headlamp switch off, the headlamps
will go off, and your DRL lamps will illuminate,
provided it is not dark outside.
Shifting the transmission into PARK (P) will allow you to
idle the vehicle with the DRL off. The DRL will stay
off until you shift the transmission out of PARK (P).
This procedure applies only to vehicles rst sold in the
United States.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release. Turning off the automatic headlamp system
with the headlamp switch is not available for vehicles
rst sold in Canada. For vehicles rst sold in Canada,
you can turn off the automatic headlamp systemwhen parked at night by applying the parking brake
before starting your vehicle. The headlamps will remain
off once the vehicle is started for as long as you are
parked. If you release the parking brake, the lights will
turn on. If the parking brake is not released before
you begin to drive, the exterior lamps will turn on above
2 mph (3.2 km/h).
Your vehicle is equipped with a light sensor located on
the top of the instrument panel in the defroster grille.
Be sure it is not covered, or the system will be on
whenever the ignition is on.
The system may also turn on your 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 sees a change in lighting lasting
longer than the delay.

Instrument Panel Cluster
Your instrument cluster is designed to let you know at a glance how your vehicle is running. You’ll know how fast
you’re going, about how much fuel you have and many other things you’ll 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.
