approved by Mercedes-Benz specifically for
your vehicle to balance the tires.
Adding balancing granulate, balancing beads
or balancing gel to the tires can damage the
inliner of the tire.

Important safety notes
G
WARNING
Underinflated or overinflated tires pose the
following risks:
R
the tires may burst, especially as the load
and vehicle speed increase.
R
the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R
the driving characteristics, as well as
steering and braking, may be greatly
impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires
including the spare wheel:
R
monthly, at least
R
if the load changes
R
before beginning a long journey
R
under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
G
WARNING
The tire temperature and pressure increase
when the vehicle is in motion. If you reduce
the tire pressure in hot tires are warm, the
tire pressure will be too low when the tires
are cold. Tire pressure that is too low can
cause the tire to burst, in particular if the
vehicle is heavily laden or at high speeds.
There is a risk of an accident.
Never reduce the tire pressure in hot tires.
Observe the prescribed tire pressures.
For every 18 ‡ (10 †) change in air
tempera-ture, the tire pressure changes by
around 30
to 40 kPa (0.3 to 0.4 bar/4.4 to 5.8 psi). Bear
this temperature-related change in tire pres-
sure in mind when checking tire pressures
indoors, where the temperature may be higher
than the outside temperature.
Example:
R
room temperature is approximately 68 ‡
(20 †).
R
outside temperature is approximately 32 ‡
(0 †).
R
set the tire pressure to around 60 to 80 kPa
(0.6 to 0.8 bar/8.7 to 11.6 psi) above that
prescribed in the tire pressure table.
The tire pressures are specified according to
E.T.R.T.O. standards and may deviate from the
manufacturer's specifications.
Also observe the general notes in the "Operat-
ing and road safety" section (
Y
page 192).
Determining tire pressures
!
Correct the tire pressures for each axle on
the vehicle.
Example: tire size and load bearing index

on the tire.
If load bearing index

is comprised of two
numbers, the first number before the "/" is for
single tires and the second number, after the
"/", is for twin tires.
