CRUISE CONTROL
•
Press the ON/OFF button if the
vehicle has dash board mounted
cruise control switches or the
CANCEL button if the vehicle has
cruise control switches on the
steering wheel.
Resuming Cruise Control
1. If you tapped the brake or
clutch pedal, the cruise control
remembered the previously set
cruise speed. To resume that
set speed, accelerate above the
minimum cruise control speed and
press the "RESUME" button.
2. If you pressed the "OFF" button
(or the steering wheel mounted
"CANCEL" button) or turned the
ignition key OFF, this cleared the
system memory and you will need
to set a new cruise speed.

NOTE
Cruise control functions and fea-
tures may vary depending upon
which engine you have. For specific
explanation of your cruise control,
see the cruise control or engine
manual included with your vehicle.
This vehicles electronic system will
perform a ‘rationality check’ every time
the vehicle is started. This check is
to ensure that the service brakes are
working before allowing cruise control
to function. This safety feature is
designed to ensure that a driver is able
to cancel the cruise set speed by using
the service brake pedal. The system
will not allow cruise control operation if
it does not pass the ‘rationality check’.
The instrument cluster will prompt you
to press the service brake pedal if it
has not been pressed since the vehicle
has been started.
