CAUTION
The red oil pressure light
is not an oil level indicator! One should therefore
check the oil level at regular intervals, preferably after every refuelling stop. Coolant
First read and observe the introductory information and safety warn- ings
on page 20.
The indicator light remains lit until the engine reaches operating temperature 2)
.
Avoid high speeds, full throttle and high engine loads.
If the warning light lights up or flashes, either the coolant temperature is too
high or the coolant level is too low.
An audible signal sounds as a warning tone.
The following message is shown in the MAXI DOT display.
Check coolant. Read manual.
Stop the vehicle, switch off the engine, check the level of the coolant » page 166,
and refill the coolant if necessary » page 167.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the radiator fan. Check the fuse for the radia-
tor fan, replace if necessary » page 193, Fuses in the engine compartment .
Do not continue driving if the warning light
does not go off even though the
coolant level is correct and the fuse for the fan is in working order!

WARNING■ If you have to stop for technical reasons, then park the vehicle at a safe dis-
tance from the traffic, switch off the engine and activate the hazard warning
light system » page 45.■
Carefully open the coolant expansion bottle. If the engine is hot, the cooling
system is pressurized - risk of scalding! It is therefore best to allow the engine to cool down before removing the cap.
■
Do not touch the radiator fan. The radiator fan may switch itself on auto-
matically even if the ignition is off.
1)
The warning light does not light up in vehicles fitted with the MAXI DOT display when the ignition
is switched on, but only if there is a fault or the engine oil level is too low.
2)
Not on vehicles with the MAXI DOT display.
22Operation

We recommend that you leave the air outlet vents 3 » Fig. 80 on page 77 in the
open position in all operating modes.
Note
If the air distribution is set only to the windows, the entire volume of air is used
to defrost the windows and thus no air will be fed to the footwell. This can limit
the heating comfort.
Recirculated air mode
First read and observe the introductory information given on page 78.
Recirculated air mode prevents polluted air from outside the vehicle getting into
the vehicle, for example when driving through a tunnel or when standing in a
traffic jam.
Switching on/off
›
Press the
button.
The indicator light in the button lights up.
›
Press the
button again.
The indicator light in the button goes out.
Recirculated air mode is switched off automatically if the air distribution control
C
» Fig. 81 on page 79 is turned to the
position. Recirculated air mode can be
switched on again from this setting by pressing the
button again.
WARNINGNever leave recirculated air mode on over a longer period of time, as “stale air”
can cause fatigue of the driver and the passengers, reduce attention levels
and also cause the windows to mist up. The risk of having an accident increa-
ses. Switch off recirculated air mode as soon as the windows start to mist up.

The cooling system operates only if the following conditions are met. The cooling system is switched on » page 81.
The engine is running.
The outside temperature is above approximately +2 °C.
The blower switch is switched on (positions 1-4).
If the desired interior temperature can also be achieved without activating the cooling system, fresh air mode should be selected.
If the coolant temperature is too high, the cooling system is switched off to en-
sure that the engine cools down.
CAUTION
■ Under certain circumstances, air at a temperature of about 5 °C can flow out of
the vents when the cooling system is switched on.■
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when getting
out of the vehicle, can cause susceptible individuals to catch a cold.
Note
We recommend that you have the air conditioning system cleaned by a specialist
garage once every year.80Operation

WARNINGNever leave recirculated air mode on over a longer period of time, as “stale air”
can cause fatigue of the driver and the passengers, reduce attention levels and also cause the windows to mist up. The risk of having an accident increa-
ses. Switch off recirculated air mode as soon as the windows start to mist up.

The distribution of the weight is very poor if your vehicle is unladen and the trail-
er is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination.
Tyre pressure
Correct the tyre inflation pressure on your vehicle for a “full load” » page 173,
Service life of tyres .
Trailer load
The permissible trailer load must not be exceeded under any circumstan- ces » page 199 , Technical data .
The trailer loads specified apply only to altitudes up to 1 000 metres above mean
sea level.
The engine output falls as altitude increases, as does the ability to climb. There-
fore, for every additional 1000 m in height (or part), the maximum permissible
towed weight must be reduced by 10 %.
The towed weight comprises the actual weights of the (loaded) towing vehicleand the (loaded) trailer.
The trailer and drawbar load information on the type plate of the towing equip-
ment are merely test data for the towing equipment. The vehicle-specific values
are detailed in the vehicle documents.WARNING■ Do not exceed the maximum permissible axle and drawbar load and the
maximum permissible total or towed weight of the vehicle and the trailer –
there is the risk of an accident and serious injury.■
Slipping loads can significantly affect the stability and safety of the vehicle/
trailer combination – there is the risk of an accident and serious injury.
Towing a trailer
First read and observe the introductory information and safety warn-
ings
on page 120.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. The national legal requirements must be observed.
Headlights
The front of the vehicle can be lifted when a trailer is being towed and the head- lights can dazzle other road users.
Adjust the headlight setting on the headlight range control » page 42, Headlight
beam adjustment .
Driving speed
For safety reasons, do not drive faster than 80 km/h when towing a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the trail- er is detected. Never attempt to stop the trailer from “swaying” by accelerating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first, then brake firmly. This will avoid brake jolts resulting from
the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as a
brake.
Engine overheating
The speed must be reduced immediately if the needle for the coolant tempera-
ture gauge moves into the right-hand area or the red area of the scale.
Stop and switch off the engine if the warning light
in the instrument cluster
starts to flash. Wait a few minutes and check the level of coolant » page 166,
Checking the coolant level .
The following guidelines must be observed » page 22,
Coolant .
The coolant temperature can be reduced by switching on the heating.WARNING■ Adapt your speed to the conditions of the road surface and to the traffic sit-
uation.■
Improper or incorrectly connected electric cables can energise the trailer and
cause functional faults to the vehicle's entire electrical system as well as acci-
dents and severe injuries.
■
Work on the electrical system must only be carried out by specialist garages.
■
Never directly connect the trailer's electrical system with the electrical con-
nections for the tail lights or other current sources.
121Towing a trailer

The oil level must be checked at regular intervals. We recommend it be checked
after each time you refuel or prior to making a long journey.
We recommend maintaining the oil level within the range A
, but not above , if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun- tain pass.
The warning light in the instrument cluster will indicate whether the oil level is too low » page 21 , Engine oil . Check the oil level using the dipstick as soon
as possible. Add oil accordingly.
CAUTION
The oil level must on no account be above range A » Fig. 130 . Risk of damaging
the exhaust system!
Note
Engine oil specifications » page 163.
Replenishing
First read and observe the introductory information and safety warn-
ings
on page 163.
›
Check the oil level » page 164.

The coolant consists of water with coolant additive. This mixture guarantees anti- freeze protection, protects the cooling/heater system against corrosion and pre-
vents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the same antifreeze identified on the coolant expansion
vessel » Fig. 131 on page 166.
WARNING■
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 159.■
Do not continue your journey if for some reason it is not possible to top
up the coolant under the prevailing conditions! Switch off the engine and seek
assistance from a specialist garage.
CAUTION
■ The concentration of coolant additive in the coolant must never be under 40%.■Over 60% of coolant additive in the coolant reduces the antifreeze protection
and cooling effect. 165Inspecting and replenishing

■A coolant additive that does not comply with the correct specifications can sig-
nificantly reduce the corrosion protection.■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 131 on page 166.
■
If a fault causes the engine to overheat, we recommend visiting a specialist ga-
rage, as otherwise serious engine damage may occur.

First read and observe the introductory information and safety warn-
ings on page 165.
The coolant expansion bottle is located in the engine compartment.
›
Switch off the engine.
›
Open the bonnet » page 161.
›
Check the level of coolant at the coolant expansion vessel » Fig. 131. The cool-
ant level when the engine is cold must lie between the
B
(MIN) and
A
(MAX)
markings. The level may also rise slightly above the
A
(MAX) marking when the
engine is warm.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light
lighting up in the instrument cluster » page 22,
Coolant .
We still recommend inspecting the coolant level directly at the reservoir from
time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a specialist
garage.
