Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
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.
If your vehicle has the Traction Control System (TCS)
and the cruise control is on, TCS will begin to limit wheel
spin and the cruise control automatically turns off. See
Traction Control System (TCS) on page 4-7. 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 left side of
the steering wheel.
T(On/Off):Press to turn cruise control on and off.
The indicator is lit when cruise control is on.
+ RES (Resume/Accelerate):Press to make the
vehicle accelerate or resume to a previously set speed.
SET– :Press to set the speed or make the vehicle
decelerate.
[(Cancel):Press to cancel cruise control.

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. SeeInstrument Panel Cluster on
page 3-31.
{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
Tbutton.
2. Get up to the desired speed.
3. Press and release the SET– button located on the
steering wheel.
4. Take your foot off the accelerator.
Resuming a Set Speed
If cruise control is set at a desired speed and the
brakes are applied, this shuts off the cruise control.
However, it does not need to be reset.
Once your vehicle reaches a speed of about 25 mph
(40 km/h) or more, press the +RES button on the steering
wheel. The vehicle goes back to the previously selected
speed and stays 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 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.

Reducing Speed While Using Cruise
Control
To reduce your 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 vehicle speed.
When you take your foot off the pedal, the vehicle
will slow down to the cruise speed you set earlier.
Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle speed, load and the steepness of
the hills. When going up steep hills, you might have to
step on the accelerator pedal to maintain your speed.
When going downhill, you might have to brake or shift
to a lower gear to keep your speed down. If the
brakes are applied the cruise control will turn off.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[button on the steering wheel.
Press theTbutton on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased by
turning off the cruise control or the ignition.
