Coolant temperature gaugeFig. 24
Coolant temperature gauge
Read and observe on page 28 first.
The display » Fig. 24 provides information on the engine coolant temperature.
The display only works if the ignition is switched on.
Cold range
If the pointer is still in the left area of the scale, this indicates that the engine has not yet reached its operating temperature. Avoid high speeds, full throttle
and high engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the middle of the scale
A
» Fig. 24 .
High temperature range
If the pointer reaches the red area of the scale, the coolant temperature is too
high.
CAUTION
■ Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.
Fuel gaugeFig. 25
Fuel gauge
Read and observe on page 28 first.
The display » Fig. 25 provides information on the fuel supply in the container.
The display only works if the ignition is switched on.
The fuel tank has a capacity of about 66 litres.
When the fuel level reaches the reserve area
A
» Fig. 25 , the warning light
» page 36 illuminates.
WARNINGFor the vehicle systems to function correctly, and thus for safe driving,
there must be sufficient fuel in the tank. Never drain the fuel tank com-
pletely – risk of accident!
CAUTION
Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring. This can result in considerable damage to parts of the en-
gine and the exhaust system.
Note
■ After filling up, it can occur that during dynamic driving (e.g. numerous
curves, braking, driving downhill and climbing a steep hill) the fuel gauge indi-
cates approx. a fraction less. When stopping or during less dynamic driving, the
fuel gauge displays the correct fuel level again. This is not a fault.■
The arrow
next to the icon
within the fuel gauge displays the installation
location of the fuel filler on the right-hand side of the vehicle.

Brakes and parking
Introduction
This chapter contains information on the following subjects:
Information on braking
132
Electric parking brake
133
Parking
134WARNING■ 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!
■
When leaving the vehicle never leave persons leave unattended in the
vehicle who could release the brake. The vehicle could then start to move –
risk of accident!
■
Observe the recommendations on the new brake pads » page 139, New
brake pads .
CAUTION
Never let the brakes slip with light pressure on the pedal if braking is not nec-
essary. This causes the brakes to overheat and can also result in a longer brak-
ing distance and excessive wear.
Information on braking
Read and observe
and on page 132 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
If operated under severe conditions , the thickness of the brake pads must be
checked by a specialist garage between service appointments as well.
132Driving
The proportion of coolant additive in the mixture must be at least 40%.
The coolant additive may be increased to a maximum of 60%.
The correct mixing ratio of water and coolant additive is to be checked if nec-
essary by a specialist garage or is to be restored if necessary.
The description of the coolant is shown in the coolant expansion reservoir
» Fig. 231 on page 211 .WARNINGThe 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 206.■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container, safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
If coolant is swallowed, consult a doctor immediately.
■
Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■ Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
ventilate - there is a risk of engine damage,
not continue! Switch off the en-
gine and seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■ Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage.■
Do not fill the coolant above the mark
A
» Fig. 231 on page 211 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
Note
The coolant capacity is approximately 1 l greater on vehicles that are fitted
with an auxiliary heater (auxiliary heating and ventilation).
