Cruise control USING CRUISE CONTROL
The cruise (speed) control system can be used
by the driver to maintain a selected vehicle
speed above 30 km/h (18 mph).
1. SET (+): Press to engage cruise control
and set the current speed. It is also used to
increase the set speed until the desired
speed is obtained.
2. RES (Resume): Resumes the cruise
control set speed after it has been
disengaged.
3. CAN (Cancel): Press to disengage cruise
control. The set speed memory will be
retained.
4. (-): Press to decrease the set speed until
the desired speed is obtained.
SETTING VEHICLE SPEED
Only use cruise control when
conditions are favourable (e.g.
straight, dry, open roads with light
traffic).
In certain conditions, such as a steep
downhill gradient, the vehicle speed
may exceed the set cruising speed.
This is because engine braking is
unable to maintain or reduce the
vehicle speed. Driver intervention
may be required.
When you are travelling at the speed you
require press the set button.
Cruise control will engage and maintain the set
speed and you can remove your foot from the
accelerator pedal.
Note: Cruise control will automatically
disengage when the brake pedal is pressed or
when the vehicle speed falls below 30 km/h (18
mph).
CHANGING THE CRUISE SPEED
There are two ways to change the set speed:
• Accelerate or decelerate to the desired
speed then press the set button.
• Increase or decrease the speed by pressing
the speed adjustment buttons SET (+) or
(-) (1 or 4) until the desired speed is
obtained.
Note: The set speed can be increased or
decreased in steps of 2 km/h (1 mph), by
pressing the speed adjustment buttons (+) or
(-) briefly until the desired speed is obtained.
RESUMING THE SET SPEED
If the vehicle is accelerated above the set
speed, then the set speed will be resumed
when the accelerator pedal is released.
If the CAN button (3) or the brake pedal is
pressed, the cruise control will disengage but
the set speed memory will be retained. Press
RES (2) and the vehicle will return to the set
speed.
Note: Cruise control will not resume at speeds
below 30 km/h (18 mph).
RES should only be used if the driver is
aware of the set speed and intends to
return to it.
It is not recommended to resume set
speed when a low gear is selected as
excessive engine speeds will occur.
