The warning light will go out if the bonnet is left open for more than 30 sec-
onds
. If no engine oil has been replenished, the warning light will come on
again after driving about 100 km.
The warning light
flashes (engine oil level sensor faulty)
The following message is shown in the MAXI DOT display.
Oil sensor: Workshop!
If the engine oil level sensor is faulty, the warning light
flashes several
times and an audible signal sounds when the ignition is turned on.
Seek assistance from a specialist garage immediately.
Coolant
Read and observe
on page 30 first.
The warning light
remains illuminated , until the engine reaches operating
temperature 1)
. Avoid high speeds, full throttle and high engine loads.
If the warning light
illuminates or flashes , either the coolant temperature is
too high or the coolant level is too low.
The following message is shown in the MAXI DOT display. Check engine coolant! Log book!
›
Stop the vehicle, switch off the engine and check the coolant lev-
el » page 137 .
›
If the coolant level is too low, add coolant to the reservoir » page 137.
If the warning light
does not illuminate , after adding coolant and switching
on the ignition, you may continue your journey.
If the coolant level is within the specified range and the indicator light is still
illuminated , then there may be a malfunction of the cooling fan.
›
Check the fuse for the radiator fan, replace if necessary » page 165, Fuses in
the engine compartment .
If the coolant level and fan fuse are both OK but the indicator light is never-
theless still illuminated,
do not continue your journey!
Seek help from a specialist garage.WARNING■
Carefully open the coolant expansion bottle. If the engine is hot, the cool-
ing 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.
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.
Power steering
Read and observe
on page 30 first.
If the warning light
illuminates , there is a fault in the power steering sys-
tem.
The power steering operates with reduced steering assist or does not function
at all.
Seek assistance from a specialist garage immediately.
Stability Control (ESC)

Let the bonnet drop into the lock carrier lock from a height of around 20 cm –
do not push it in !
WARNING■
Check that the bonnet is closed properly.■If you notice that the lock is not properly engaged while driving, stop the
vehicle immediately and close the bonnet – risk of accident!■
Make sure that when closing the boot lid, no body parts are crushed -
there is danger of injury!

123456133Inspecting and replenishing
›Pull the dipstick out again and check the oil level.
The engine consumes a little oil. The oil consumption may be as much as 0.5 l/
1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. Consumption may be slightly higher than this during
the first 5 000 km.
The oil level must be checked at regular intervals.
In case of low oil level, the display of the instrument cluster shows a check
mark
as well as the relevant notification » page 31. Check the oil level using
the dipstick as soon as possible. Add oil accordingly.
CAUTION
■ The oil level must never be above the range A» Fig. 125 - risk of damage to
the motor as well as the exhaust system!■
Do not continue your journey if for some reason it is not possible to top up
the engine oil!
Switch off the engine and seek assistance from a specialist
garage.
■
If the oil level is above level

do not continue to drive! Switch
off the engine and seek assistance from a specialist garage.

Replenish the oil in portions of 0.5 litres in accordance with the correct speci-
fications » page 135 .

Coolant
Introduction
This chapter contains information on the following subjects:
Checking the coolant level
137
Replenishing
137
The coolant provides cooling for the motor.
It consists of water and coolant additive with additives that protect the cooling
system against corrosion and prevents furring.
The coolant additive content in the coolant 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 reser-
voir » Fig. 126 on page 137 .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 131.■
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 pressurised!
■
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 your journey if for some reason it is not possible to fill with
coolant under the current circumstances! Switch off the engine and seek as-
sistance 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.
136General Maintenance
■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. 126 on page 137
■
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.

Mark for the maximum permissible coolant level
Mark for the lowest permissible coolant level
The coolant level should be kept between the marks

The coolant can be checked and topped up, if the following conditions are sat-
isfied.
The vehicle is standing on a horizontal surface.
The engine is turned off.
The engine is not heated.
The bonnet is open.
Checking the level
›
Check the coolant level in the coolant expansion tank » Fig. 126.
If the engine is warm, the test result may be inaccurate. The level can also be
above the mark
A
» Fig. 126 .
ABIn case of low coolant level, the control symbol is displayed in the instrument
cluster as well as the relevant notification » page 32. We still recommend in-
specting 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 cooling sys-
tem. Do not merely top up the coolant. Have the cooling system checked by a
specialist garage.
Replenishing
Read and observe
and on page 136 first.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the
cap carefully .
›
Replenishing the coolant.
›
Turn the cap until it clicks into place.
CAUTION
■
Only top up with new coolant.■Do not use an alternative additive if the specified coolant is not available. In
this case, use just water and have the correct mixing ratio of water and cool-
ant additive restored by a specialist garage as soon as possible.
