Brakes and Parking
Introduction
This chapter contains information on the following subjects:

Parking

The wear of the brake pads is dependent on the operating conditions and driv-
ing style. Under difficult conditions (e.g. urban, sporty driving style) the condi-
tion of the brakes should also be checked by a specialist garage between the
service intervals.
The performance of the brakes can be delayed if the brakes are damp, iced up
in winter or if covered in a layer of salt . The brakes are cleaned and dried by
applying the brakes several times »
.
Corrosion on the brake discs and dirt on the brake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned by applying the brakes several times »
.
Before travelling a long distance with a steep gradient , reduce speed and
shift into the next lowest gear. As a result, the braking effect of the engine will
be used, reducing the load on the brakes. If you do have to brake, this should
be carried out at intervals.
Emergency braking display - when an emergency braking is performed, the
automatic flashing of the brake lights are used to alert the traffic behind.
New brake pads must first be “worn in” because these do not initially have the
best possible braking effect. Drive especially carefully for the first 200 km or
so.
A too low brake fluid level can cause faults in the braking system , the warn-
ing light  illuminates in the instrument cluster
» page 35,
 Brake system
. If
the warning light does not illuminate and an extended stopping distance is re-
quired, then driving should be adapted according to the unknown cause of
fault and restricted braking effect - seek the assistance of a specialist garage
immediately.
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.
WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
During the braking procedure on a vehicle with manual transmission,
when the vehicle is in gear and at low revs, press the clutch pedal. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
Do not press the brake pedal if braking is now required. This causes the
brakes to overheat and can also result in a longer braking distance and ex-
cessive wear - risk of accident!
■
Braking for the purpose of drying and cleaning the brake discs should be
carried out only if the traffic conditions permit. Do not place any other road
users in jeopardy.
■
Recommendations for new brake pads have to be observed.
■
When stopping and parking, the parking brake should always be on, oth-
erwise the vehicle could move off - there is the risk of an accident!
■
If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must
be ensured that the air supply to the front wheel brakes is not reduced.
Otherwise, the functionality of the brake system may be impaired – risk of
accident!

The coolant additive proportion in the coolant must be between 40 and 60 %.
The correct mixing ratio of water and coolant additive should be checked if
necessary by a specialist garage or corrected if necessary.WARNING■ The following warning instructions must be followed at all times when
working in the engine compartment » page 268.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized - risk of scalding or
injury from being splashed with coolant!
■
To protect against coolant splashes, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
your eyes or skin come into contact with the coolant, immediately wash the
affected area for a few minutes long with a lot of water and seek medical
advice if required.
CAUTION
Do not cover the radiator or fit any parts (e.g. auxiliary lights) in front of the air
intakes - there is a risk of the engine overheating.
Checking and refilling
Fig. 322
Coolant expansion reservoir
Read and observe and on page 272 first.
Check the coolant under the following conditions and refill.
The vehicle is on a horizontal surface.
The engine is not warm (if the engine is warm, the test results could be
inaccurate).
The engine is turned off.
Check the coolant level - The coolant level must lie between the marks A andB» Fig. 322. If the coolant level is below the mark B, refill the coolant.
Refilling
The coolant expansion tank must always contain a small amount of coolant
»
.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the
cap carefully .
›
Always top up using the correct specification of fluids.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» Fig. 322 .
If no specified coolant is available, use only distilled or demineralised water
and have the mixing ratio of water and coolant additive corrected by a special-
ist garage as soon as possible.
CAUTION
■ If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of damaging the engine!  Stop driving! Switch off the engine
and seek assistance from a specialist garage.■
Do not fill the coolant above the mark
A
» Fig. 322 . When it heats up, the
coolant could press out of the cooling system - there is a risk of damage to the
engine parts.
■
If it is not possible to add coolant, 
stop driving! Switch off the engine and
seek assistance from a specialist garage.
■
A coolant additive which does not correspond to the correct specification can
reduce the anti-corrosion effect of the cooling system - there is a risk of dam-
age to the cooling system and the engine.
■
If water other than distilled (demineralised) water is used, then have the
coolant replaced by a specialist garage - there is a risk of engine damage.
■
A loss of coolant could be due to leaks in the cooling system - there is a risk
of engine damage. Switch off the engine and seek assistance from a specialist
garage.
Note
A coolant level which is too low is indicated in the instrument cluster by the
warning light  and shown by the relevant message » page 39. We still recom-
mend inspecting the coolant level directly at the reservoir from time to time.272General Maintenance

›For vehicles with
manual transmission , set the lever in the neutral position.›On vehicles with automatic transmission , place the selector lever in the P
position.›
Start the engine.
›
Plug the connector

into 12 volt socket » page 96.
›
Switch on the air compressor with the ON and OFF switch

.
›
Once a tyre inflation pressure of 2.0-2.5 bar is reached, turn off the air com-
pressor. Maximum run time of 6 minutes » .
›
If you cannot reach an air pressure of 2.0 - 2.5 bar, unscrew the tyre inflation
hose
7
from the tyre valve.
›
Drive the vehicle approx. 10 metres forwards or backwards to allow the seal-
ing agent to “distribute” in the tyre.
›
Firmly screw the tyre inflation hose
7
back onto the tyre valve and repeat
the inflation process.
›
Stick the corresponding sticker
1
on the dashboard in the driver's field of
view.
Once a tyre inflation pressure of 2.0 – 2.5 bar is achieved, continue the journey
at a maximum speed of 80 km/h (50 mph).
WARNING■ If the tire does not inflate at least. 2.0 bar, the damage is too great. The
sealing agent cannot be used to seal the tyre.  Stop driving! Seek help
from a specialist garage.■
The tyre inflation hose and air compressor may get hot as the tyre is be-
ing inflated – risk of burning.
CAUTION
Switch off the air compressor after running 6 minutes at the most – risk of
overheating! Allow the air compressor to cool a few minutes before switching
it on again.
Information for driving with repaired tyres
Read and observe
on page 285 first.
The inflation pressure of the repaired tyre must be checked after driving for 10
minutes.
If the tyre inflation pressure is 1.3 bar or less
›
The tyre cannot be properly sealed with the breakdown kit. 
Do not drive
the vehicle! Seek help from a specialist garage.
If the tyre inflation pressure is 1.3 bar or more›Set the tyre pressure back to the correct value » page 277.›
Continue driving carefully to the nearest specialist garage at a maximum
speed of 80 km/h (50 mph).
WARNINGA tyre filled with sealant has the same driving characteristics as a standard
tyre. The following guidelines must be observed.■
Do not drive faster than 80 km/h (50 mph).
■
Avoid accelerating at full throttle, sharp braking and fast cornering.
Jump-starting
 Introduction
This chapter contains information on the following subjects:
