Oils and fluids
Checking and topping up the
brake and clutch fluid
The brake and clutch fluid have a common
1
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 brake
fluid grade on page 217.
The fluid should be changed annually on cars
driven in conditions requiring hard, frequent
braking, such as driving in mountains or
tropical climates with high humidity.
1. Location dependent on whether car is
left or right-hand drive.
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.
Maintenance and service
Checking and topping up the
power steering fluid
Check the level at every service. The fluid
does not require changing. The fluid level
must be between the MIN and MAX marks.
See the capacities and recommended oil
grade on page 217.
If a fault should arise in the power steering
system or if the car is without power and must
be towed, it can still be steered. However the
steering will be much heavier than normal and
it will require more effort to turn the wheel.
