Tire Pressure - Mercedes-Benz S-Class 2011 Operator's Manual

"Technical Data" section to avoid damage
to the vehicle or the wheels.
Only use snow chains when driving on an
R
area completely covered by snow. Do not
exceed the maximum permissible speed of
30 mph (50 km/h). Remove the snow
chains as soon as possible when you are no
longer driving on snow-covered roads.
Local regulations may restrict the use of
R
snow chains. Applicable regulations must
be observed if you wish to mount snow
chains.
Snow chains must not be mounted on
R
emergency spare wheels.
If you intend to mount snow chains, please
bear the following points in mind:
you may not attach snow chains to all
R
wheel-tire combinations; see the "Tires and
wheels" section in the "Technical data"
chapter.
mount snow chains only in pairs and only
R
on the rear wheels. Observe the
manufacturer's installation instructions.
! If snow chains are mounted on the front
wheels, the snow chains could grind
against the bodywork or components of the
chassis. This could result in damage to the
vehicle or the tires.
! Vehicles with steel wheels
If you wish to mount snow chains to steel
wheels, make sure that you remove the
respective wheels' hubcaps first. The
hubcaps may otherwise be damaged.
i You may wish to deactivate
®
ESP ( Y page 69) when pulling away with
snow chains installed. This way you can
allow the wheels to spin in a controlled
manner, achieving an increased driving
force (cutting action).

G
Warning
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
You will find a table of recommended tire
pressures on the Tire and Loading
Information placard on the B-pillar on the
driver's side ( Y page 490). You will find a
table of tire pressures for various operating
conditions on the inside of your vehicle's fuel
filler flap.
Use a suitable pressure gauge. The outer
appearance of a tire does not permit any
reliable conclusion about the tire pressure.
On vehicles equipped with the electronic tire
pressure monitor, the tire pressure can be
checked using the on-board computer.

Warning
