WARNING (Continued)
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.
