If
the brake warning lamp does
not go out,

or
if it

the
brake
flu­

id level in
the
reservoir
is too low -
this
may

cause an increased accident risk. Stop

A WARNING
- To avoid the risk of being scalded, never
open the bonnet if
you
see steam or coolant
escaping from the engine compartment.
Wait until no steam or coolant can be seen
before opening the bonnet.
- For safety reasons the bonnet must always
be completely closed when the vehicle is

moving.
After closing it always check that it
is properly secured. It should not be possi­

- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be
scal­

ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children - risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off- risk of injury!
Brake fluid
© CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling
system - risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­

tance.

- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­

pected.
This applies particularly if
you
drive
into a colder climate zone.
-To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­

ble.
In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.

Please refer to the safety notes
^page
295,
Working on components in the engine compart­
ment.
Checking brake fluid level
Read off the brake fluid level on the brake fluid
reservoir
^>page
297, Fig. 245. The brake fluid
level must be between the MIN and MAX marks

<=>A.

The brake fluid
level
is also automatically moni­

tored.

In right-hand drive vehicles the brake fluid reser­
voir is on the other side of the engine compart­
ment.
Changing brake fluid
Have the brake fluid changed regularly by a quali­
fied workshop.
WARNING
-If the brake fluid Level is under the MIN
mark, the effectiveness of the brakes and
therefore the safety of the vehicle may be
impaired - risk of accident! Do not drive on.
Obtain professional assistance.
- Heavy use of the brakes may cause a vapour
lock if old brake fluid is left in the system.
This would seriously impair the effective­
ness of the brakes and the safety of the car
- risk of accident!
© CAUTION
- If the brake fluid level is above the MAX
mark, brake fluid may escape via the cap on •
