Cur
bw eight
The weight of avehicle with standard
equipment includin gthe maximum capacity
of fuel, oil and coolant .Italso includes the air-
conditionin gsystem and optional equipment
if these are installed in the vehicle, but does
not include passengers or luggage.
Maximu mload rating
The maximum tir eload is the maximum
permissible weight in kilograms or lbs for
which atireisa pproved.
Maximu mpermissible tir epressure
Maximum permissible tir epressure for one
tire.
Maximu mload on one tire
Maximum load on one tire. This is calculated
by dividin gthe maximum axle load of one axle
by two.
PSI (pounds per squar einch)
As tandar dunitofm easure for tire pressure.
Aspect ratio
Relationship between tire height and tire
width in percent.
Tirep ressure
This is pressure inside the tire applying an
outward forc etoeach square inch of the tire's
surface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure should only
be corrected when the tires are cold.
Cold tirep ressure
The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has been driven for less than
1m ile (1.6 km). Tread
The part of the tire that comes intoc
ontact
with the road.
Bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to preven tthe tire from
comin gloose from the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kilograms (5 lbs).
These optional extras, such as high-
performance brakes, level control, aroof rack
or ah igh-performanc ebattery, are not
included in the curb weight and the weight of
the accessories.
TIN (Tire Identification Number)
This is aunique identifier which can be used
by atire manufacturer to identify tires, for
example for aproduct recall, and thus identify
the purchasers. The TIN is made up of the
manufacturer's identity code, tire size, tire
type code and the manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of atire.
Traction
Traction is the result of friction between the
tires and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are
distributed over the tire tread. If the tire tread
is level with the bars, the wear limit of 0014in
(1.6 mm) has been reached. 356

Important safety notes G
WARNING
If antifreez ecomes into contact with hot
components in the engine compartment, it
may ignite. There is arisk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreez eisnot
spilled next to the filler neck.T horoughly
clean the antifreeze from components before
startingt he engine.
! Only add coolant that has been premixed
with the desired antifreezep rotection. You
coul dotherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 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 corrosio nand
overheating.
Comply with the important safety precautions
for service products when handling coolant
(Y page3 73). The coolant is
amixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
R corrosio nprotection
R antifreeze protection
R raising the boiling point
If the coolant has antifreeze protection down
to -35 ‡(-37 †), the boiling point of the
coolant during operatio nisapproximately
266 ‡(130 †).
The antifreeze/corrosion inhibitor
concentration 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 not exceed 55% (antifreeze protection
down to -49 ‡[-45 †]). Otherwise, heat
will not be dissipated as effectively.
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in
accordance with MB Specifications for
Service Products 310.1.
The coolant is checked with every
maintenance interval at aqualified specialist
workshop.
i When the vehicle is first delivered, it is
filled with acoolant mixture that ensures
adequate antifreeze and corrosion
protection.
