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 find this to
be too much trouble and don't use cruise control on
steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:

Step lightly on the brake pedal or push the clutch
pedal, if you have a manual transmission.

Move the cruise switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.Exterior Lamps
The control on the driver's side of the instrument panel
operates the exterior lamps
The exterior lamps control has three positions:
(Parking Lamps): Turning the exterior lamps
control to this position turns on the parking lamps
together with the following:

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights

2-48
(Headlamps): Turning the exterior lamps control to
this position turns on the headlamps, together with the
previously listed lamps and lights.
(Off): Turn the exterior lamps control all the way
counterclockwise to turn off the lamps and put the
system in automatic headlamp mode.
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 dim.
Your vehicle is equipped with a light sensor on the top
of the instrument panel under the radio speaker grill. 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.
As with any vehicle, you should turn on the regular
headlamps when you need them.
You may be able to turn off your Automatic Headlamp
System. See ªDaytime Running Lamps (DRL)º later in
this section for more information.
Lamps On Reminder
A reminder chime will sound when your headlamps
or parking lamps are manually turned on and your
ignition is in OFF, LOCK or ACCESSORY. To turn
the chime off, turn the exterior lamps control all the
way counterclockwise to OFF or turn the instrument
panel dimmer down to the fully dimmed position. In
automatic mode, the headlamps turn off once the
ignition key is in OFF.

2-49 Daytime Running Lamps (If Equipped)
(Optional)
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 first sold in Canada.
The DRL system will make your headlamps come on at
reduced brightness when the following conditions are met:

The ignition is on,

the exterior lamps control is in OFF,

the light sensor detects daytime light,

an automatic transmission is not in PARK (P), and

the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular
headlamps.
The DRL system on some vehicles may turn off
temporarily while the turn signals are activated.To idle an automatic transmission vehicle with the DRL
off, put the transmission in PARK (P) or set the parking
brake. To idle a manual transmission vehicle with the
DRL off, set the parking brake. The DRL will stay
off until you shift out of PARK (P) or release the
parking brake.
The following does not apply to vehicles first sold
in Canada.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running Lamps
(DRL) feature by following these steps. When the
system is turned off, the headlamps will not
automatically come on when it becomes dark outside.
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you the
system is off.
3. The system will revert back to the automatic mode
when the DOME OVERRIDE button is again pushed
four times within six seconds (a chime will sound),
or when the ignition is turned off and on again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-50 Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps or low
-beam headlamps
must be on for your fog lamps to work.
The fog lamp button is on the instrument panel near the
exterior lamps control.
Press the button to turn the fog lamps on. Press the
button again to turn them off. A light will glow in the
switch when the fog lamps are on.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high
-beam headlamps
go off, the fog lamps will come on again.
Interior Lamps

if the DOME OVERRIDE button is in the out position.
If your vehicle is equipped with Remote Keyless Entry
and all the doors are closed, or the front door handles
are lifted and released, the lamps will stay on for a short
period of time and will turn off automatically. If you use
your keyless entry transmitter to unlock the vehicle, the
interior lights will come on for a short time whether or
not the DOME OVERRIDE button is in the out position.

2-51 Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition to help you see
while exiting the vehicle. These lights will stay on for a
short period of time and then will go out, if the DOME
OVERRIDE button is in the out position.
Front Map Lamps (If Equipped)
If your vehicle has front map lamps, they are located
on the inside rearview mirror. They will automatically
come on for approximately 40 seconds when the doors
are unlocked with the keyless entry transmitter (if
equipped) or until the ignition key is turned to RUN
or ACCESSORY. The lamps will also stay on for
approximately 40 seconds after you exit the vehicle,
unless you lock the doors with the keyless entry
transmitter.
You can also turn the lamps on and off by pressing the
switch near each lamp.
Dome Lamps
The dome lamps will come on when you open any door.
You can also turn the dome lamps on by turning the
thumbwheel, located next to the exterior lamps control,
all the way up to the second notch. In this position, the
dome lamps will remain on whether a door is opened or
closed.
You can use the DOME OVERRIDE button, located
below the exterior lamps control, to set the dome lamps
to come on automatically when any door is opened, or to
remain off. To turn the lamps off, press the button in.
With the button in, the dome lamps will remain off when
any door is opened. To return the lamps to automatic
operation, press the button again and return it to the out
position. With the button in this position, the dome
lamps will come on when you open any door. This will
override the illuminated entry feature, unless you use
your keyless entry transmitter (if equipped) to unlock
the vehicle.
