WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbit ein
the immediate vicinity of the air vents. There
is ar isk of injury.
Make sure that all vehicle occupants always
maintain asufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. In order to ensure the direct flow of fresh air
through the air ventsi
nto the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the ventsorv entilation grilles

Problem
Possible causes/consequences and
M
MSolutions Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or in amechanical
componentoft he engine management system.
X Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at aqualified specialist
workshop. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be on and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 382). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct,t
he engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X If the coolant temperature is below 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrain and stop-start traffic. Manual transmission
Gear lever
! Only engage gear when the clutch pedal is
depressed.
! When shifting between
5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift unintentionally into 3rdor4th gear
and damage the transmission.
If you shift down at too high aspeed (trans-
mission braking), this can cause the engine to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise arisk of damaging the
clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing a trailer, you must shift into gear
1, 2or3in
good time. This uses the engine's braking
effect.T his relieves the load on the brake
system and preventst he brakes from over-
heating and wearing too quickly. k

Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is arisk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is adanger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren. 200

If you must drive on stretches of road on
which water has collected, please bear in
mind that:
R in the case of standing water, the water
level must be no highert han the loweredge
of the vehicle body
R you shouldd rive no faster than walking

G
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.

i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
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
speed, for braking in good time, and for stay- ing in lane.
If there is achange of drivers, advise the new
driver of the speed stored.
You can set avariable or permanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when driving with winter tyres
