Restarting the tire pressure monitor
Whenyourestart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rentlys et tire pressures as the reference values
for monitoring. In most cases, the tire pressure
monitor will automaticall ydetect the new refer-
ence value safteryou have changed the tire
pressure. However, yo ucan also set reference
value smanually as described here. The tire
pressure monitor then monitors the new tire
pressure values.
XSet the tire pressure to the value recommen-
ded for the corresponding driving situation on
the Tire and Loading Information placard on
the driver'ss ideB -pillar (
Ypage 290).
Yo uc an find more tire pressure value sfor

sure table inside the fue lfille rflap

This could damage the engine.
Brake fluid
GWARNING
The brake flui dconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low,v aporpockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is arisk of an accident.
You should have the brake flui dreneweda t
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(
Ypag e315).
The brake flui dchange interval scan be found in
the Maintenance Booklet.
Only use brake flui dapproved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval3 31.0.
Information about approved brake flui dcan be
obtained at any qualified specialist workshop or
on the Internet at
http://bevo.mercedes-benz.com.
iHave the brake flui dregularl yreplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly cleant he
antifreeze from components before starting
the engine.
!Only add coolant that has been premixed
with the desired antifreeze protection. You
coul dotherwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aqualified specialist workshop.
!Always use asuitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosiona nd
overheating.
iHave the coolant regularl yreplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypag e315).
The coolant is amixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaising the boiling point
If the coolant has antifreeze protection down to -35 ‡(-37 †), the boiling point of the coolant
during operation is approximatel y266 ‡
(130 †).
