table for different numbers of occupants and
amounts of luggage. The actual number of
seats may differ. Example: tire pressure table with tire dimensions
Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18 . The rim diameter is part of the tire size
and can be found on the tire sidewall
(Y page 348). If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset
to the higher values:
R if you want to drive with an increased load
and/or
R if you want to drive at higher road speeds.
i The tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
i For vehicles towing a trailer, the full load
value on the tire pressure label located on the inside of the fuel filler flap is valid for
the rear axle.
Option 3) The tire pressure for the
emergency/collapsible spare wheel
(depending on vehicle equipment) can be
found:
R printed in yellow on the rim of the
emergency/collapsible spare wheel
R in the "Wheel and tire combinations"
section ( Ypage 359) in this Operator's
Manual
R on the Tire and Loading Information placard
on the B-pillar on the driver's side
If the tire pressure is not set correctly, this
can lead to an excessive build up of heat and
a sudden loss of pressure.
For more information, contact a qualified
specialist workshop. Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
R Check the tire for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage,
contact a qualified specialist workshop. G
WARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire
pressure monitors keep the tire valve open.
This can also result in tire pressure loss. There
is a risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve. Tire pressure

shown on pressure gauge 0087.
! Do not operate the tire inflation
compressor for longer than eight minutes
at a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.
X Inflate the tire to the specified tire
pressure.
The specified tire pressure is printed on the
yellow label of the emergency spare wheel.
X When the specified tire pressure has been
reached, press on/off switch 0083on the
electric air pump to 0.
The tire inflation compressor is switched
off. X
Turn the SmartKey to position 0in the
ignition lock.
X If the tire pressure is higher than the
specified pressure, press pressure release
button 0044until the correct tire pressure has
been reached.
X Unscrew union nut 0043on the air hose from
the valve.
X Screw the cap onto the valve of the
collapsible spare wheel again.

Stowing a used collapsible spare wheel Take the following steps to stow a used
collapsible spare wheel. Otherwise, the
collapsible spare wheel will not fit in the spare
wheel well. Mercedes-Benz recommends that
you have this work carried out at a qualified
specialist workshop.
!
Only place the collapsible spare wheel in
the vehicle when it is dry. Otherwise,
moisture may get into the vehicle.
X Remove the valve extractor from the
vehicle tool kit.
X Unscrew the valve cap from the valve.
X Unscrew the valve insert from the valve and
release the air.
i Fully deflating the tires can take a few
minutes.
X Screw the valve insert back into the valve.
X Screw the valve cap back on.
X Place the valve extractor back into the
