Refueling
Drivin ga nd parking

If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
Have you rv ehicle winter-proofed at aq ualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control or
Distance Pilo tD ISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed: X
Shift the transmission to position N .X
Try to bring the vehicle under control using
corrective steering.
The outsid et emperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outsid et emperature are dis-
played after as hort delay.
Indicated temperature sj ust above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
woode da rea soronb ridges.
You shoul dp ay specia la ttention to road condi-
tions when temperature sa re around freezing
point.
For more information on driving with snow
chains, see ( Y

For more information on driving with summer
tires, see ( Y

Observe the notes in the "Winter operation" sec-
tion ( Y

Cruise control
General notes
Cruise control maintains ac onstant road speed
for you .Itb rakes automatically in order to avoid
exceeding the set speed .Onl ong and steep
downhill gradients, especially if the vehicle is
laden, you must select al ow gear in good time.
You need to shift manually using the steering
wheel paddle shifters beforehand. By doing so,
you wil lm ake use of the braking effect of the engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
When the engine is running, you can use the
cruise control lever to limi tt he speed to any
speed betwee n20m ph (30 km/h )a nd the tech-
nicall yp ermitted maximum speed of the vehicle.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain as teady
speed for ap rolonge dp eriod.
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes If you fail to adapt you rd riving style, cruise con-
trol can neither reduce the risk of an accident
nor override the law sofp hysics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control is only an
aid .Y ou are responsible for the distance to the
vehicle in front, for vehicle speed ,f or braking in
good time and for staying in you rl ane.
Do not use cruise control: R
in road and traffic conditions which do not
allow you to maintain ac onstant speed ,e .g. in
heavy traffic or on winding roads R
on slippery road surfaces .B raking or accel-
erating could cause the drive wheel stol ose
traction and the vehicle could then skid R
in poor visibility, e.g. due to fog, heavy rain or
snow
If there is ac hange of drivers, advise the new
driver of the speed stored.
