WARNING Risk of burn s from hot com‐
ponent parts in the engine compartment
Cer tain component parts in the engine com‐
partment can be very hot, e.g. the engine,
th e cooler and parts of theex haust sy stem.
#Let the engine cool down and only
to uch the component parts described
as follo ws .

WARNING Danger of burn s from hot
coolant
The engine cooling sy stem is pressurized,
particularly when the engine is warm. If you
open the cap, you could be scalded byhot
coolant spr aying out.
#Let the mo tor cool down before opening
th e cap.
#When opening the cap, wearglove s and

Notes on brake fluid
Obser vethe no tes on operating fluids
(→page 447).
&
WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
te m
The brake fluid cons tantly absorbs moist ure
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be
impaired.
#Ha ve the brake fluid rene we d at the
specified inter vals.
Ha ve the brake fluid regularly changed at a quali‐
fi ed specialist workshop.
Only use brake fluid appr ovedby Mercedes-Benz
according toMB-F reigabe or MB-Appr oval 33 1.0. Fu
