164 Driving and parking
If you accelerate to overtake, for example, the
stored speed is not deleted. If you remove your
foot from the accelerator pedal after overtaking,
cruise control will resume speed regulation back
to the stored speed.
You can operate cruise control with the cruise
control lever.
If you fail to adapt your driving style, cruise con‐
trol can neither reduce the risk of an accident
nor override the laws of physics. It cannot take
into account road, weather or traffic conditions.
Cruise control is only an aid. You are responsible
for the distance to the vehicle in front, for vehi‐
cle speed, for braking in good time and for stay‐
ing in your lane.
System limitations
Cruise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Do not use cruise control in the following situa‐
tions:
In traffic situations which require frequent
R
changes of speed, e.g. in heavy traffic, on
winding roads.
On slippery roads. Accelerating can cause
R
the drive wheels to lose traction and the
vehicle could then skid.
When visibility is poor.

Operating cruise control
& WARNING Risk of accident due to
unknown stored speed
If you call up the stored speed and this is
lower than your current speed, the vehicle
decelerates.
If you do not know the stored speed, the
vehicle could decelerate unexpectedly.
Take into account the traffic situation
#
before calling up the stored speed.
If the stored speed is not known, store
#
the desired speed again.
Change into a lower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving a laden vehicle. By
doing so, you will make use of the braking effect
of the engine. This relieves the load on the brake
system and prevents the brakes from overheat‐
ing and wearing too quickly.
Requirements
Cruise control is selected.
R
®
ESP
must be switched on, but not interven‐
R
ing.
The driving speed must be at least 15 mph
R
(20 km/h).
