The start of the red zone on the dial indicates the maximum engine speed
which may be used briefly when the engine is warm and after it has been run
in properly. However, it is advisable to change up a gear or move the selector
lever to D (or lift your foot off the accelerator) before the needle reaches the
red zone.
Caution
The rev counter needle must never enter the red zone on the scale. Risk of
engine damage.
For the sake of the environment
Changing up a gear early will help you to save fuel and minimise engine
noise.Engine coolant temperature display

This gauge shows the engine coolant temperature.
The display only works when the ignition is switched on. The symbol  will also light up in the display for some seconds as a function
check.Needle in cold zone
Avoid high engine speeds and heavy engine loads ⇒fig. 45 .
Needle in normal zone
In normal driving conditions, the needle should be in the middle section of
the scale. The temperature may also rise when the engine is working hard,
especially at high outside temperatures. This is no cause for concern, as long
as the warning lamp does not light up ⇒page 72.
Needle in warning zone
The warning lamp  will light up if the needle is in the warning zone. The
warning text

the combi-instrument display. Stop the car and switch off the engine. Allow
the engine to cool and check the coolant level ⇒.
Even if the coolant level is correct do not continue driving . You should obtain
technical assistance.
WARNING
Read and observe the warnings “Working in the engine compartment”
before opening the bonnet to carry out work in the engine compartment.
Caution
Accessories in front of the air inlet reduce the cooling effect of the coolant. At
high outside temperatures and high engine loads, there is a risk of the
engine overheating.

Overview
80Coolant Level* / temperature

The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.There is a fault if:•
The warning symbol does not go out again after a few seconds.
•
The warning lamp lights up or flashes while the vehicle is moving, while
three acoustic warning signals ⇒ are emitted.
This means that either the coolant level is too low or the coolant temperature
is too high.
Coolant temperature too high
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch off the engine and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. Check the radiator fan fuse and have it replaced if neces-
sary ⇒page 243.
If the warning lamp lights up again after driving on for a short distance, stop
the vehicle and switch off the engine . Contact an Authorised Service Centre
or a qualified workshop.
Coolant level too low
The following information text is displayed in the instrument panel display:
First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity ⇒.
WARNING
•
If your vehicle is immobilised for any technical reasons, move it to a
sa fe dista n ce from tra ffic. Tu rn o ff the en gin e , tu rn o n the ha za rd ligh ts a nd
place the warning triangle.
•
Never open the bonnet if you can see or hear steam or coolant escaping
from the engine compartment. Risk of scalding. Wait until you can no
longer see or hear escaping steam or coolant.
•
The engine compartment of any motor vehicle is a dangerous area!
Before carrying out any work in the engine compartment, switch off the
engine and allow it to cool down. Always note the corresponding warnings.

An audible signal is also given if the car is driven faster than 6 km/h (approx.
4 mph) with the handbrake applied.
Coolant temperature/level gauge

The corresponding warning is:
STOP CHECK LEVEL COOLANT
SERVICE MANUAL.
If the symbol flashes while driving, this means that either the coolant temper-
ature is too high or the coolant level is too low. Stop immediately, switch off
the engine and check the level. Top up coolant if necessary.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. In this case, check the radiator fan fuse, and replace if
necessary.
If the warning light does not go out, although the coolant level is correct and
the fan fuse is correct, do not continue driving. Obtain technical assistance.
If the fault is only in the radiator fan, it is possible to continue driving as far
as the nearest Technical Service Centre, as long as the coolant level is correct
and the display light is off.
Alternator

The corresponding warning is:
ALTERNATOR WORKSHOP!
The warning lamp lights up when the ignition is switched on. It should go out
when the engine is started.
The alternator is operated by a long-lasting drive belt.
If the warning light lights up while driving, stop, switch off the engine and
check the drive belt. If the belt is loose or broken, do not continue driving, as
the coolant pump will not be driven. The belt should be checked or replaced.
If the warning light comes on even though the belt is neither loose nor
broken, it is usually possible to continue driving to the nearest Technical
Service Centre.
As the vehicle battery will discharge, it is advisable to switch off all non-vital
electrical consumers.
Seat belt warning lamp

The corresponding warning is:
FASTEN SEAT BELT
This warning light (only in some countries) lights up for approximately 6
seconds when the ignition is switched on to remind occupants to fasten seat-
belts. If the seat belts are not fastened, a sound signal is emitted when the
ignition is switched on which will stop when the seat belts are fastened or
after approximately 6 seconds.
WARNING
•
If the brake fluid level is below the “MIN” mark, you should wait for
assistance from specialised personnel before continuing to drive.
•
If the fluid level is correct, the fault may lie in the ABS. If the ABS control
system fails, the rear wheels may block rapidly on braking. This, in certain
circumstances, could cause the vehicle to skid.
•
Never open the bonnet if you see steam or coolant escaping from the
engine compartment. Risk of burns. Wait until you can no longer see or
hear escaping steam or coolant.
•
Do not touch the fan, as it could suddenly start to operate, even if the
ignition is switched off.
•
To prevent burns from boiling coolant, the following should be
observed:
•
Take care when opening the coolant expansion tank!. When the engine
is warm or hot, the system is pressurised! Therefore wait until the engine
cools before opening the cap.

Air vents in the roof
In vehicles with a second cooling system
39) for ventilating the passenger
compartment, an air outlet is fitted in the roof above each rear seat
⇒ fig. 122 .
The air outlets in the roof can be opened and closed individually and
adjusted by moving the grid.
Each air outlet has two thumb wheels. The left thumb wheel can be used to
open and close the air outlet. The right thumb wheel can be used to direct the
air towards the head and chest.
WARNING
Never leave objects, food or medicines in front of the air outlets in the rear
seats. The hot air could damage or destroy heat-sensitive objects, food or
medicines.
Caution
Do not use the area in front of the outlets to store objects. This could cause
the blower to overheat and switch off. The blower could also be damaged.
Note
In the cooling mode, at least one air outlet in the roof must be open. The
cooling system could otherwise ice over.
General notesThe pollution filter
The pollution filter serves as a barrier against impurities in the ambient air (
e.g.dust and pollen).
For the air conditioning system to work with maximum efficiency, the pollen
filter must be replaced at the intervals specified in the Service Schedule.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the pollen filter must be changed more frequently than
stated in the Service Schedule.
Instructions for use
If the air conditioning or Climatronic
40) is not switched on for a long period,
deposits on the evaporator can cause unpleasant smells. To prevent these
odours, the cooling system should be run at the highest blower setting at
least once a month when temperatures are over +5°C. Briefly open a window
at the same time.
Faults in the operation of the air conditioning
There is a fault if the all the symbols in the Climatronic flash for approx. 15
seconds when the ignition is switched on. Contact a specialist workshop.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•
the engine is not running.
•
The blower is switched off.
•
The outside temperature is lower than +5°C.
•
the cooling system compressor has been temporarily switched off
because the engine coolant temperature is too high.
•
The air conditioning fuse is faulty.

– Press and hold the lock button, move the selector lever to P and
release the lock button.
Driving up and down hills
– Press the selector lever from position D to the right into the
“Tiptronic” selector gate.
– Lightly press the selector lever back to change down.
Holding the car on a hill
– You should always hold the vehicle in position with the footbrake
to stop it from “rolling backwards” ⇒. Do not try to prevent
the vehicle from “rolling backwards” by increasing the engine
speed while a range of gears is selected
Moving away on an incline
– With a gear engaged, take your foot from the brake and depress the accelerator.The steeper the gradient, the lower the gear you will need. This increases the
braking effect of the engine. For example, you should drive down a very steep
slope in 3rd gear. If the engine brake effect is not sufficient, the vehicle will
gain speed. The automatic gearbox / direct shift gearbox automatically
changes up to prevent the engine over revving. Use the foot brake to reduce
speed and change into 3rd gear using “Tiptronic” ⇒.
Your vehicle has an automatic interlock which prevents the selector lever
being put into a position for driving forwards or in reverse from positions P or
N if the brake pedal is not depressed.
The ignition key cannot be removed unless the selector lever is in position P.
WARNING
•
As a driver you should never leave your vehicle if the engine is running
and a gear is engaged. If you have to leave your vehicle while the engine is
running, you must apply the parking brake and engage parking lock P.
•
If the engine is running and if D, S or R is engaged, you will need to hold
the car on the foot brake. The car will creep forward as the power transmis-
sion is not fully interrupted even when the engine is idling.
•
Never press the accelerator when you move the selector lever. Risk of
accident.
•
Never move the selector lever to R or P when driving. Risk of accident!
•
Before you drive down a steep gradient, reduce your speed and use
“Tiptronic” to select a low gear.
•
If you have to stop the vehicle on a gradient, always hold the vehicle in
position using the foot brake to stop it from rolling back.
•
Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking will cause the brakes to overheat and
will considerably reduce the brake effect. This increases the braking
distance and could cause the brake system to fail.
•
Never allow the car to roll down a gradient with the gear in neutral N, or
in selector lever position D, even if the engine is not running.Caution
•
If you stop the vehicle on a gradient, do not attempt to stop it from rolling
by depressing the accelerator when a gear has been selected. Otherwise, the
automatic gearbox /direct shift gearbox* may overheat causing damage. Pull
the handbrake on fully or depress the brake pedal to prevent the vehicle from
rolling away.
•
If you allow the car to roll with the selector lever in position N with the
engine switched off, the automatic gearbox / direct shift gearbox* will be
damaged as it will not be lubricated.

Note
The two clutch system of the direct shift gearbox* has a system to protect
against excess strain, which may occur, for example, when the vehicle is held
on a hill with the clutch and the gearbox oil overheats. When the clutch is
overloaded, the vehicle begins to jerk and the position indicator of the
selector lever begins to flash. To avoid breakdowns, the clutch breaks the
power transmission between the engine and the gearbox, as a result of which
the vehicle loses impetus. If the clutch opens automatically due to over-
loading, depress the brake pedal and wait a few seconds before
continuing.Selector lever positions
The selector lever positions and gears are shown on the
display in the combi-instrument.
Selector lever positions
The gear selected is displayed on the side of the selector lever and on the
display ⇒fig. 129 in the combi-instrument.
P - parking lock
When the selector lever is in this position, the drive wheels are locked
mechanically.
The parking lock must be engaged only when the vehicle is stationary ⇒ .
To move the selector lever from position P, the locking button in the selector
lever handle must be pressed and the brake pedal depressed at the same
time when the ignition is switched on.
Only the locking button has to be pressed to select the selector lever position
P .
If the battery has discharged, the selector lever cannot be removed from the
P position.
R - reverse gear
The reverse gear is engaged in this position.
Reverse gear must be engaged only when the vehicle is stationary and the
engine is idling ⇒.
To move the selector lever to position R, press in the lock button and at the
same time press the brake pedal, with the ignition switched on.
With the selector lever in position R and the ignition switched on the
following occurs:•
The reversing lights come on.
•
The heating or air conditioning automatically change to air recirculation
mode.
•
The rear window heater switches on when the windscreen wiper is acti-
vated.

Intelligent technology
184•
If the brake warning lamp
 should light up together with the ABS
warning lamp
, stop the vehicle immediately and check the brake fluid
level in the reservoir ⇒page 223. If the fluid level has dropped below the
“MIN” mark you must not drive on. Risk of accident. You should obtain
professional assistance.
•
If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS control function. This could cause the
rear wheels to lock quickly when you brake. This could cause the tail of the
vehicle to skid sideways. Drive carefully to the nearest qualified workshop
and have the fault corrected.
Electronic differential lock (EDL)
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.The electronic differential lock (EDL) only works when the engine is running.
EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
It uses the ABS sensors to monitor the speed of the driven wheels.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheels of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.
To prevent the disc brake of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The car remains operational
and will behave in the same way as a car without EDL. For this reason, the
driver is not informed that the EDL has been switched off. The EDL will switch on again automatically when the brake has cooled down.
WARNING
Try to always adapt the speed of the vehicle to weather, road and traffic
conditions. Do not let the extra safety afforded by the system tempt you
into taking any risks when driving. Risk of accident.•
When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may other-
wise start to spin. This could impair the car's stability.
•
Always adapt your driving style to suit road conditions and the traffic
situation.WARNING
Modifications to the vehicle or work carried out incorrectly (e.g. to the
engine, the brake system, running gear or any components affecting the
wheels and tyres) could affect the efficiency of the ABS, EDL, ESP and TCS
and lessen their efficiency.Electronic stabilisation programme (ESP)
The electronic stabilisation programme helps to reduce the
danger of skidding.The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS
and only works when the engine is running.
The ESP should generally be left switched on at all times. Only when the
necessary drive can not be obtained should the ESP be disconnected.
For example:•
when driving with snow chains,

Driving and the environment
188If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the car, the effect of the brakes is less-
ened as the brake discs are wet or even frozen (in winter): in this case, “dry”
the brakes by applying the brakes carefully several times
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•
New brake pads must be run in and do not have the correct friction
during the first 200 km. The slightly reduced braking effect can be compen-
sated for by increasing pressure on the brake pedal. This also applies when
new brake pads are fitted.
•
If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.
•
When driving downhill, the brakes work hard and get hot very quickly.
Before driving down a long steep gradient, it is advisable to reduce speed
and change to a lower gear (or move the selector lever to a lower gear if
your vehicle has automatic transmission). In this way you will make use of
the engine braking effect and relieve the load on the brakes.
•
Never let the brakes “rub” by only applying light pressure. Continuous
braking will cause the brakes to overheat and will increase the braking
distance. Apply and then release the brakes alternately.
•
Never let the vehicle coast with the engine switched off. The braking
distance is increased considerably as the brake servo does not work.
•
Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This impairs the braking effect.
•
Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the notes ⇒page 204 before
buying accessories.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gas emission control systemCatalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not run the fuel tank dry.
– For engine oil changes, do not replenish with too much engine oil ⇒page 217, “Topping up engine oil ”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 250.If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest qualified workshop. These symptoms are communicated by the
exhaust gas warning lamp ⇒page 72. If this happens, unburnt fuel can enter
the exhaust system and escape into the environment. The catalytic converter
can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Fire hazard!•
Never park where the catalytic converter could come into contact with
dry grass or inflammable materials under the vehicle.
•
Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system, because the heat from the engine could ignite them.

Caution
Never fully drain the fuel tank, in this case, the irregularity of the fuel supply
may cause ignition problems. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust under some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be reme-
died by changing to another brand of fuel.Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.The diesel engine dust filter eliminates most of the soot from the exhaust gas
system. Under normal driving conditions, the filter cleans itself. If driving
conditions do not allow the filter to clean itself (for example, multiple short
trips) the filter will be obstructed by dust and pollen and the diesel engine
particulate filter warning lamp will light up.
WARNING
•
The diesel engine particulate filter may reach extremely high tempera-
tures; it should not enter into contact with flammable materials under-
neath the vehicle. Failure to comply could result in fire.
Caution
•
The vehicle is not designed for refuelling with mixtures of FAME fuel
(biodiesel) over 7% in accordance with DIN 51628. The diesel particle filter
will be damaged if this mixture percentage is exceeded.
Economical and environmentally friendly
drivingEconomical and environmentally friendly drivingFuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends in large part on your driving style. By adopting an econom-
ical driving style and anticipating the traffic situation ahead, you can easily
reduce fuel consumption by 10-15%. Some tips on how to help you reduce
pollution while saving money are listed below.
As you drive try to anticipate the traffic situation
A vehicle uses most fuel when accelerating. By anticipating the situation, you
are required to brake less often and, therefore accelerate less. If it is possible,
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero
(disconnection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up through the gears quickly.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.

NoteBy law, the ball coupling must be removed if a trailer is not being towed and
it obscures the number plate.•
When placing the towing bracket in the casing check that it is no longer
tensed and securely fastened.
Driving tips
Driving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the car and trailer is reduced with increasing speed. For this
reason it is advisable not to drive at the maximum permissible top speed in
unfavourable road, weather or wind conditions. This applies especially when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of snaking . Never try to stop the “snaking” by increasing speed.
Always brake in good time. If the trailer has an overrun brake, apply the
brakes gently at first and then firmly. This will prevent the jerking that can be
caused by the trailer wheels locking. Select a low gear (in both manual and
automatic gearboxes) in good time before going down a steep hill. This
enables you to use the engine braking effect to slow down the vehicle. Overheating
At very high temperatures and during prolonged ascents, driving in a low gear
and high engine speed, always monitor the temperature indicator for the
coolant.
Electronic Stabilisation Program
Do not switch off the ESP when towing a trailer. The ESP makes it easier to
stabilise if the trailer starts to snake.
