The coolant expansion bottle is located in the engine compartment.
Inspecting the coolant level
›
Switch off the engine.
›
Open the bonnet.
› Check the coolant level in the coolant expansion tank
» Fig. 185.
Coolant level above mark A
No coolant must be refilled.
The level may also rise slightly above the
A
marking when the engine is warm.
Coolant level between markings
A
and
B
Coolant can be refilled.
When the engine is cold, the coolant level must lie between the
A
and
B
mark-
ings.
Coolant level below mark
B
Coolant must be refilled.
When the engine is cold, refill the coolant between the markings
A
and
B
.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning icon
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.
Replenishing
First read and observe the introductory information and safety warn-
ings
on page 221.
Only refill with new coolant.
›
Switch off the engine.
›
Allow the engine to cool.
›
Place a cloth over the cap of the coolant expansion reservoir and unscrew the cap carefully .
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
1)
On vehicles that are fitted with an auxiliary heater (auxiliary heating and ventilation), the coolant ca-
pacity is approx. 1 l larger.
222General Maintenance

Do not use an alternative additive if the specified coolant is not available in anemergency. In this case, use just water and have the correct mixing ratio of waterand coolant additive restored by a specialist garage as soon as possible.
Brake fluid
Introduction
This chapter contains information on the following subjects:
Checking the brake fluid level
223
Changing
223WARNING■ 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 215.■
If the fluid level has dropped below the MIN marking » Fig. 186 on page 223,
do not continue your journey - risk of accident! Seek help from a specialist
garage.
■
Do not use used brake fluid - the function of the brake system may be im-
paired – risk of accident!
CAUTION
Brake fluid damages the paintwork of the vehicle.
Note
The brake fluid is changed as part of a prescribed inspection services.
Checking the brake fluid levelFig. 186
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 223.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
›
Open the bonnet.
›
Check the level of brake fluid in the reservoir » Fig. 186.
The level must be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and automatic adjustment of the brake pads.
There may be an indication of a leak in the brake system, however, if the fluid lev-
el drops significantly within a short time or if it drops below the “MIN” marking.
If the brake fluid level is too low, this is indicated by the indicator light » page 16 ,
Brake system lighting up in the instrument cluster.
Changing
First read and observe the introductory information and safety warn-ings
on page 223.
Brake fluid absorbs moisture. Over time it therefore absorbs moisture from the
environment.
Excessive water in the brake fluid may be the cause of corrosion in the brake sys-
tem.
The water content lowers the boiling point of the brake fluid.
