CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.
Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise switch to ON.
2. Get up to the speed you want.
3. Press in the SET button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.

2-33
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts off
the cruise control. But you don't need to reset it.
Once you're going about 25 mph (40 km/h) or more,
you can move the cruise switch from ON to R/A
(Resume/Accelerate) briefly.
You'll go right back up to your chosen speed and
stay there.
Remember, if you hold the switch at R/A longer, the
vehicle will keep going faster until you release the
switch or apply the brake. So unless you want to go
faster, don't hold the switch at R/A.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:

Use the accelerator pedal to get to the higher speed.
Press the SET button at the end of the lever, then
release the button and the accelerator pedal. You'll
now cruise at the higher speed.
Move the cruise switch from ON to R/A. Hold it
there until you get up to the speed you want, and
then release the switch. (To increase your speed in
very small amounts, move the switch to R/A briefly.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.)
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Press the SET button at the end of the lever until you
reach the lower speed you want, then release it.

To slow down in very small amounts, press the
button briefly. Each time you do this, you'll go about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.

2-34
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 have to step on the
accelerator pedal to maintain your speed. If the
steepness of the hill causes the vehicle speed to drop
more than 15 mph (24 km/h) below the set speed, your
cruise control will automatically disengage. 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

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

be turned off by turning the thumbwheel next to the
parking lamp/headlamp knob all the way down.
Daytime Running Lamps
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 lights are required on all
vehicles first sold in Canada.
The DRL system will make your headlamps come on
at a reduced brightness when the following conditions
are met:

the ignition is on,

the headlamp switch is off 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.
Your instrument panel won't be lit up either.
When it begins to get dark, your DRL indicator light is a
reminder to turn your headlamp knob on. The other lamps
that come on with your headlamps will also come on.

2-36
When you turn off the headlamp knob, the regular lamps
will go off, and your headlamps will change to the
reduced brightness of DRL.
To idle your vehicle with the DRL off, set the parking
brake. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
