Setting Cruise Control - Buick 2008 Lucerne Owner's Manual

Setting Cruise Control

Cruise control will not work if the parking brake is set, or
if the master cylinder brake fluid 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. See Instrument Panel Cluster on
page 3-33.
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 and release the SET– button located on the
steering wheel.

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.
