Disengaging Conditions
When the cruise control has been
engaged, there are various conditions on
which it disengages. Cruise control is
deactivated when:
• Vehicle speed is outside the
programmed limit values.
• Parking brake is operated.
• Clutch is operated.
• Foot brake is operated.
• Position 'OFF' on the steering
wheel switch (2) is operated or the
adjustable vehicle speed limiting
'SET' is activated using the
steering wheel switch (3).
• ABS/ASR system is activated.
Engaging Cruise Control
Activate cruise control by toggling the
steering wheel switch (1) once briefly to the
'SET+' position or to the 'SET–' position
when the required control speed is
reached. Cruise control can be activated
when the vehicle speed is 22.3 mph (36
km/h) or more (or another value
programmed by the Authorized
Dealership).
Modifying Cruise Control Speed
When cruise control is activated, the speed
can be increased by pressing 'SET+' or be
decreased by pressing 'SET–' on the
steering wheel switch (1). Briefly operate
the switch to increase or decrease speed
in small increments of 0.31 mph (0.5 km/h).
Keep the switch down to gradually
increase or decrease speed.
This limits the minimum and maximum
adjustable speeds by values programmed
in the electronic unit. These values can be
modified within specific limits by an
authorized Service dealer.
Accelerator Pedal Function during
Cruise Control
When cruise control is active, the vehicle
speed can be increased above the control
speed using the accelerator pedal. When
the accelerator pedal is released, the
vehicle speed will return to the last valid
control speed.
Disengaging Cruise Control
Press the 'OFF' switch (2) on the steering
wheel to deactivate cruise control.
