Buick LaCrosse: Cruise Control

Buick LaCrosse: Cruise Control

With cruise control, the vehicle can maintain a speed of about 40 km/h (25 mph) or more without keeping your foot on the accelerator. Cruise control does not work at speeds below 40 km/h (25 mph).

On vehicles with the Traction Control System (TCS) or the StabiliTrak® system, it may begin to limit wheel spin while you are using cruise control. If this happens, the cruise control will automatically disengage. See Traction Control System (TCS) or StabiliTrak® System.

WARNING!
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.

The cruise control buttons are located on the steering wheel.

(On/Off): Press to turn the cruise control system on and off. An indicator light will turn on or off in the instrument panel cluster.

(Cancel): Press to disengage cruise control without erasing the set speed from memory.

RES/+ (Resume/Accelerate):

Move the thumbwheel up to make the vehicle resume to a previously set speed or to accelerate.

SET/− (Set/Coast): Move the thumbwheel down to set the speed and activate cruise control or make the vehicle decelerate.

Setting Cruise Control

If the cruise button is on when not in use, it could get bumped and go into cruise when not desired. Keep the cruise control switch off when cruise is not being used.

1. Press to turn the cruise control system on. The indicator light in the instrument panel cluster comes on.

2. Get to the speed desired.

3. Move the thumbwheel down toward SET/− and release it.

The desired set speed briefly appears in the instrument panel cluster.

4. Take your foot off the accelerator pedal.

Resuming a Set Speed

If the cruise control is set at a desired speed and then the brakes are applied or the is pressed, the cruise control is disengaged without erasing the set speed from memory.

Once the vehicle reaches about 40 km/h (25 mph) or more, move the thumbwheel up toward RES/+ briefly. The vehicle returns to the previous set speed and stays there.

Increasing Speed While Using Cruise Control

If the cruise control system is already activated:

• Move the thumbwheel up toward RES/+ and hold it until the vehicle accelerates to the desired speed, and then release it.

• To increase the speed in small amounts, move the thumbwheel up toward RES/+ briefly, then release it. Each time this is done, the vehicle goes about 1.6 km/h (1 mph) faster.

Reducing Speed While Using Cruise Control

If the cruise control system is already activated:

• Move the thumbwheel toward SET/− and hold until the desired lower speed is reached, then release it.

• To slow down in small amounts, move the thumbwheel toward SET/− briefly and then release it.

Each time this is done, the vehicle goes about 1.6 km/h (1 mph) 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 control 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 maintain the vehicle's speed. When the brakes are applied the cruise control shuts off.

Ending Cruise Control

There are three ways to end cruise control:

• To disengage cruise control, step lightly on the brake pedal; when cruise control disengages, the indicator light will not be lit.

• Press on the steering wheel.

• To turn off the cruise control, press on the steering wheel.

Erasing Speed Memory

The cruise control set speed is erased from memory by pressing or if the ignition is turned off.
