Engaging Cruise Control
DANGER
DO NOT use the cruise control in heavy
trafc, with ice/snow on the road or during
other unfavorable conditions. This can
lead to a loss of vehicle control, causing a
vehicle crash, personal injury or death.
CAUTION
Transmission gear changes must not be
made without the use of the clutch while
in the cruise control mode. Failure to use
the clutch will cause the engine speed

which can cause severe powertrain
damage.
The cruise control maintains a set speed

through the system switches.

not be applied.
• The clutch must be engaged (pedal
released).
Once the above conditions are satised,
activate the cruise control as follows
1 On the left-hand steering wheel

ON/OFF button.
