G
Risk of accident
If the boiling point of the brake fluid is too
low, vapour pockets may form in the brake
system when the brakes are subjected to a
heavy load (e.g. on long downhill stretches).
This would impair braking efficiency. The ve-
hicle’s stopping distance may then be lon-
ger. This increases the risk of an accident.
Have the brake fluid renewed every 2 years.
The clutch mechanism and the brake sys-
tem are operated hydraulically using brake
fluid.
The reservoir is in the engine compart-
ment. Check the brake fluid level:
I
regularly, e.g. weekly or when refuelling
I
only with the vehicle standing on a lev-
el surface and with the engine switched
off
1 Brake fluid reservoir
The brake fluid level must be between the
MIN and MAX marks.
i There is usually a notice in the engine com-
partment to remind you when the next brake
fluid change is due.
! Brake fluid corrodes paintwork. If brake flu-
id comes into contact with the paintwork, im-
mediately rinse with water.
If the brake fluid does not reach the MIN mark,
the vehicle’s hydraulic system could be faulty.
Have the system checked immediately at a
qualified specialist workshop, e.g. a Mercedes-
Benz Service Centre.
Windscreen washer system/head-
lamp cleaning system
Add windscreen washer fluid concentrate
to the water all year round.
G
Risk of fire/explosion
Windscreen washer concentrate is highly
flammable.
Fire, naked flames and smoking are there-
fore prohibited when you are handling wind-
screen washer concentrate.
! Only use windscreen washer fluid which is
suitable for plastic lamp lenses. Unsuitable
windscreen washer fluid could damage the
plastic lamp lenses of the headlamps.
Adapt the mixing ratio to the ambient tem-
peratures. Use:
I
Summerwash to protect against smear-
ing at temperatures above freezing
I
Winterwash when there is a risk of
frost so that the water does not freeze
onto the windscreen
