ter.
i The recommended pressures for various
operating conditions can be found:
R on the Tire and Loading Information plac-
ard with the recommended tire pres-
sures on the B-pillar on the driver's side
R in the tire pressure table on the inside of
the fuel filler flap
Observe the notes on recommended tire
pressure under various operating condi-
tions.
Check tire pressures regularly, and only
when the tires are cold. Comply with the
maintenance recommendations of the tire
manufacturer in the vehicle document wal- let.
Further information on recommended tire
pressures as well as tire pressures for spe-
cific driving situations, see (Y page 325).
i Notes on the vehicle equipment – always
equip the vehicle with:
R tires of the same size on a given axle
(left/right)
R tires of the same type on your vehicle at
a given time (summer tires, winter tires,
all-weather tires, all-terrain tires)
i The following pages contain information
on approved wheels and tire sizes for
equipping your vehicle with winter tires.
Winter tires are not available at the factory as standard equipment or optional extras.
If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding
size. The size of the approved winter tires
may differ from the standard tires. This is
dependent on the model and the equip-
ment installed at the factory.
The tires and wheel rims, as well as further
information, can be obtained at a qualified
specialist workshop.
i Not all wheel and tire combinations are
available at the factory for all countries. 332

WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied
hard. This would impair braking efficiency.
There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
When handling brake fluid, observe the
important safety notes on service products
(Y page 337).
The brake fluid change intervals can be found
in the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com. i
Have the brake fluid regularly replaced at
a qualified specialist workshop and the
replacement confirmed in the Maintenance Booklet. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk 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 clean the
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications for Service Products, MB BeVo 310.1, e.g.
on the Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.
! Always use a suitable coolant mixture,
even in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance Booklet.
Comply with the important safety precautions for service products when handling coolant
(Y page 337). 342
Service products and filling capacitiesTechnical data

The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R corrosion protection
R antifreeze protection
R raising the boiling point
If the coolant has antifreeze protection down to -35 ‡(-37 †), the boiling point of the cool-
ant in the pressurized system is approx-
imately 266 ‡ (130 †).
The antifreeze/corrosion inhibitor concentra- tion in the engine cooling system should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
R no t exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will no t be dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor in accordance with MB
Specifications for Service Products 310.1.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
i The coolant is checked with every main-
tenance interval at a qualified specialist
workshop.
The engine cooling system is filled with cool-
ant at the factory which contains antifreeze/
corrosion inhibitor that ensures protection
down to approximately -35 ‡ (-37 †).
Your vehicle has a range of aluminum com-
ponen ts. Aluminum components in the
engine make it necessary to use antifreeze/
corrosion inhibitor that has been specifically
formulated to protect the aluminum parts.
Failure to use such anticorrosion/antifreeze
coolant will result in a significantly shortened
service life.
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and to provide protection from
overheating. In the Maintenance Booklet, you can find information on the intervals for
renewal.
The renewal interval is determined by the
coolant type and the engine cooling system
design. The renewal interval in the Mainte-
nance Booklet is only valid if the coolant is
renewed or added to with Mercedes-Benz
approved products. Therefore, only use MB
326.0 antifreeze/corrosion inhibitor or
another Mercedes-Benz approved product of the same specification.
Information on other products with the same
specifications that are approved by
Mercedes-Benz can be obtained at an author- ized Mercedes-Benz Center or on the Internet at http://bevo.mercedes-benz.com.
If the coolant level is too low, MB 325.0 anti-
freeze/corrosion inhibitor should be added.
Have the engine cooling system checked for
possible leaks.
