138Refueling
Drivin gand parking

If you leave the engine or the auxiliary heatingrunning, 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 rvehicle winter-proofed at aqualified
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 PilotD ISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
XTry to bring the vehicle under control using
corrective steering.
The outsidet emperature indicator is not
designed to serve as an ice-warning device and is therefore unsuitable for that purpose.
Changes in the outsidet emperature are dis-
played after ashort delay.
Indicated temperature sjust above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
woodeda reasoronb ridges.
You shoul dpay speciala ttention to road condi-
tions when temperature sare around freezing
point.
For more information on driving with snow
chains, see (
Ypage 290).
For more information on driving with summer
tires, see (
Ypage 289).
Observe the notes in the "Winter operation" sec-
tion (
Ypage 289).

Cruise control
General notes
Cruise control maintains aconstant road speed
for you .Itbrakes automatically in order to avoid
exceeding the set speed.Onl ong and steep
downhill gradients, especially if the vehicle is
laden, you must select alow gear in good time.
You need to shift manually using the steering
wheel paddle shifters beforehand. By doing so,
you willm 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 limitt
he speed to any
speed between20m ph (30 km/h)and the tech-
nicallyp ermitted maximum speed of the vehicle.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain asteady
speed for aprolongedp eriod.
The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes
If you fail to adapt you rdriving style, cruise con-
trol can neither reduce the risk of an accident
nor override the lawsofp 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 rlane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain aconstant speed,e .g. in
heavy traffic or on winding roads
Ron slippery road surfaces .Braking or accel-
erating could cause the drive wheelstol ose
traction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rain or
snow
If there is achange of drivers, advise the new
driver of the speed stored.
