Check the coolant regularly
The level should lie between the MIN and 
MAX marks on the expansion tank. If the 
system is not filled sufficiently, high local 
temperatures could occur, causing a risk of 
damage (cracks) in the cylinder head. Top up 
the coolant when the level falls to the MIN 
mark. 
Checking and topping up the brake 
and clutch fluid
The brake and clutch fluid have a common 
reservoir

. The fluid level must be between
the MIN and MAX marks. Check the level 
regularly. Change the brake fluid every other 
year or at every other regular service.
See the capacities and recommended fluid 
grade on page 241.
The fluid should be changed annually on cars 
driven in conditions requiring hard, frequent 
braking, such as driving in mountains or trop-
ical climates with high humidity.
WARNING
The coolant may be very hot. If the coolant 
requires topping up when the engine is at 
operating temperature, unscrew the expan-
sion tank cap slowly to gently release the 
overpressure.
NOTE
The engine must only be run with a well-
filled cooling system. High temperatures 
can occur, causing a risk of damage 
(cracks) to the cylinder head.

WARNING
If the brake fluid is under the
MIN
level in
the brake fluid reservoir, do not drive further 
before topping up the brake fluid.
The reason for the loss of brake fluid must 
be investigated.
