Check the coolant regularly<br />
The level should lie between the MIN and<br />
MAX marks on the expansion tank. If the<br />
system is not filled sufficiently, high local<br />
temperatures could occur, causing a risk of<br />
damage (cracks) in the cylinder head. Top up<br />
the coolant when the level falls to the MIN<br />
mark.<br />
WARNING<br />
The coolant may be very hot. If the coolant<br />
requires topping up when the engine is at<br />
operating temperature, unscrew the expansion<br />
tank cap slowly to gently release the<br />
overpressure.<br />
NOTE<br />
The engine must only be run with a wellfilled<br />
cooling system. High temperatures<br />
can occur, causing a risk of damage<br />
(cracks) to the cylinder head.<br />
Checking and topping up the brake<br />
and clutch fluid<br />
The brake and clutch fluid have a common<br />
reservoir 1 . The fluid level must be between<br />
the MIN and MAX marks. Check the level<br />
regularly. Change the brake fluid every other<br />
year or at every other regular service.<br />
See the capacities and recommended fluid<br />
grade on page 237.<br />
The fluid should be changed annually on cars<br />
driven in conditions requiring hard, frequent<br />
braking, such as driving in mountains or tropical<br />
climates with high humidity.<br />
WARNING<br />
If the brake fluid is under the MIN level in<br />
the brake fluid reservoir, do not drive further<br />
before topping up the brake fluid.<br />
The reason for the loss of brake fluid must<br />
be investigated.<br />
