Cruise control
Function of cruise control
Cruise controlaccelerates and brakes thevehicle
automaticallyinorder to maintain apreviously
stored speed.
If youacceleratetoovertake, forexample, the
stored speed is notdeleted. If youremove your
foot from theaccelerator pedal afterovertaking,
cruise control will resume speed regulation back
to thestoredspeed.
Cruise controlisoperated using thecorrespond‐
ing steering wheel buttons. Youcan storeany
road speed above 15 mph(20 km/h).
If youfail to adaptyour driving style, cruise con‐
trol can neither reduce therisk of an accident nor
override thelaws of physics. It cannottakeinto
account road, weather or trafficconditions.
Cruise control is only an aid. Youare responsible
forthe distance to thevehicle in front, forvehicle
speed, braking in good time and forstaying in
your lane.

System limitations
Cruise control maybeunable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when thegradient evens out.
On long and steep downhill gradients, youshould
changedowntoalowergear in good time. Take
particular note of this when driving aladen vehi‐
cle. By doing so, youwill makeuse of the
engine'sbraking effect. Thisrelievesthe load on
thebrake system and prevents thebrakesfrom
overheating and wearing tooquickly.
Do notuse cruise control in thefollowing situa‐
tions:
R
In trafficsituations where frequent speed
changes arerequired, e.g. in heavy trafficor
on winding roads.
R
On slippery roads. Accelerating can cause the
drivewheels to lose traction and thevehicle
could then skid.
R
If youare drivingwhen visibilityispoor.

To activatecruise control: pushrocker
switch 1 up.
#
Remove your foot from theaccelerator pedal.
The current speed is then savedand main‐
tained by thevehicle.

To increase/reduce speed: push rocker
switch 2 up or down.
The stored speed is increased or reduced by
