WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle .This is the case, e.g. if the vehicle
becomes trapped in snow. There is arisk of
fatal injury.
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 yourv ehicle winterproofe dataqualified
specialist workshop at the onset of winter.
You shouldd rive particularly carefully on slip-
pery road surfaces .Avoid sudden accelera-
tion, steering and braking manoeuvres. If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission:
shift to neutral.
X Vehicles with automatic transmission:
shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
The outsid etemperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outsid etemperature are dis-
played after ashort delay.
Indicated temperature sjust above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areasoronb ridges. The
vehicle could skid if you fail to adapt your
driving style. Alwaysa dapt yourdriving style
and drive at aspeed to suit the prevailing
weather conditions.
You shouldp ay specialattention to road con-
ditions when temperature sare around freez-
ing point.

Further information on driving safety systems (Y page7 7). Cruise control
General notes Cruise control maintains
aconstant road
spee dfor you.Itb rakes automatically in order
to avoi dexceeding the set speed. You must
select alow gearing ood time on long and
steep downhill gradients, especially if the
vehicl eisladen or towing atrailer. By doing
so, you willm ake use of the braking effect of
the engine. This relieves the loadont he brake
system and prevents the brakes from over-
heating and wearing too quickly.
Use cruise control only if road and traffic con- ditions are appropriate for maintaining a
stead yspee dfor ap rolonged period. You can
store any road spee dabove 30 km/h.
Important safety notes If you fail to adapt yourd
riving style,cruise
control can neither reduce the risk of an acci-
dent nor overrid ethe lawsofp hysics. Cruise
control cannot take into account road,
weather or traffic conditions. Cruise control is only an aid.Y ou are responsibl efor the dis-
tance to the vehicl einfront, for vehicl espeed,
for braking in good time, and for staying in the lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintai naconstant speed
(e.g. in heavy traffic or on winding roads)
R on smooth or slippery roads. Braking or
accelerating can caus ethe drive wheels to
lose traction and the vehicl ecouldt hen
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow If there is
achange of drivers, advise the new
drive rofthe spee dstored.

Important safety notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. Change into
al ower gear in good time on long and steep
downhill gradients. Take particular noteof
this when driving aladen vehicle. By doing so,
you will make use of the braking effect of the engine. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an
accident nor override the laws of physics.
SPEEDTRONIC cannot take into account
road, weather or traffic conditions. SPEED-
TRONIC is only an aid. You are responsible for
the distance to the vehicle in front,f or vehicle

If there is achange of drivers, advise the new
