Cruise Control
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not 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 excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When the brakes are applied, the cruise control
turns off.
If your vehicle has the StabiliTrak
®system and begins
to limit wheel spin while you are using cruise control,
the cruise control will automatically disengage.SeeStabiliTrak
®System on page 4-8. When road
conditions allow you to safely use it again, the cruise
control can be turned back on.
The cruise control buttons
are located on the left side
of the steering wheel.
I(On/Off):Press button to activate and turn off the
system. The indicator light on the button turns on
when cruise control is on.
+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
SET−(Set/Coast):Press this button to set the speed
or make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise control
without erasing the set speed from memory.

Setting Cruise Control
Cruise control will not work if the parking brake is set, or
if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
comes on after the cruise control has been set to
the desired speed.
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Press the cruise control On/Off button.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose the cruise control is set at a desired speed
and then the brake is applied. This shuts off the cruise
control. But it does not need to be reset.
Once the vehicle is driving at about 25 mph (40 km/h)
or more, press the +RES button on the steering
wheel. The vehicle will go back to the previous set
speed and stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until the new desired speed is reached,
then release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle goes about 1 mph (1.6 km/h) faster.
3-15

Reducing Speed While Using Cruise
Control
To reduce the vehicle’s speed while using cruise
control:
Press and hold the SET– button on the steering
wheel until the desired lower speed is reached,
then release it.
To slow down in very small amounts, press the
SET– button on the steering wheel briey.
Each time this is done, the vehicle goes about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle’s
speed. When you take your foot off the pedal, the
vehicle will slow down to the previous set cruise speed.
Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicle’s speed, load, and the steepness of the
hills. When going up steep hills, you might have to
step on the accelerator pedal to maintain the vehicle’s
speed. When going downhill, you might have to brake
or shift to a lower gear to keep the vehicle’s speed
down. When the brakes are applied the cruise control
turns off. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the clutch pedal to the oor (manual
transmissions).
Press the cancel button on the steering wheel.
Press the On/Off button on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.

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 make either the reduced intensity
low-beam headlamps or dedicated DRL’s come on
when the following conditions are met:
It is still daylight and the ignition is in ON/RUN or
START.
The exterior lamp control is in off or AUTO and the
headlamps are off.
The automatic transmission is not in PARK (P).
When DRL’s are on, only the reduced intensity
low-beam headlamps or dedicated DRL’s will be on.
No other exterior lamps will be on. The instrument panel
cluster will not be lit up either.When the exterior lamp control is in AUTO and it is dark
enough outside, the DRL turns off and the low-beam
headlamps will turn on. When it is bright enough outside,
the low-beam headlamps will go off, and the DRL will
turn back on. If the vehicle is started in a dark garage,
the automatic headlamp system comes on immediately.
Once the vehicle leaves the garage, it takes about
one minute for the automatic headlamp system
to change to DRL if it is light outside. During that delay,
the instrument panel cluster may not be as bright as
usual. Make sure the instrument panel brightness lever
is in the full bright position. SeeInstrument Panel
Brightness on page 3-20.
Turning the exterior lamp control to off or to the
low-beam headlamp position will turn off the DRL.
If the parking lamps or the fog lamps were turned on
instead, the DRL will still turn off.
This will work regardless of gear position and whether
or not the parking brake is set.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
ignition to ON/RUN. If it does not come on then, have it
xed so it will be ready to warn you if there is a problem.When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does
not release fully. If it stays on after your parking brake
is fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice that the
pedal is harder to push, or the pedal may go closer to
the oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing Your
Vehicle on page 4-28.
{CAUTION:
The brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can
lead to an accident. If the light is still on after
the vehicle has been pulled off the road and
carefully stopped, have the vehicle towed for
service. United StatesCanada
