Emergency spare wheel
Important safety notes
GWARNING
The wheel or tire size as well as the tire type ofthe spare wheel or emergency spare wheel
and the wheel to be replaced may differ.
Mounting an emergency spare wheel may
severely impair the driving characteristics.
There is a risk of an accident.
To avoid hazardous situations:
R adapt your driving style accordingly and
drive carefully.
R never mount more than one spare wheel or
emergency spare wheel that differs in size.
R only use a spare wheel or emergency spare
wheel of a different size briefly.
R do not switch ESP ®
off.
R have a spare wheel or emergency spare
wheel of a different size replaced at the
nearest qualified specialist workshop.
Observe that the wheel and tire dimensions
as well as the tire type must be correct.
When using an emergency spare wheel or
spare wheel of a different size, you must not
exceed the maximum speed of 50 mph
(80 km/h).
Snow chains must not be mounted on emer-
gency spare wheels.
General notes
You should regularly check the pressure of
the emergency spare wheel, particularly prior
to long trips, and correct the pressure as nec-
essary ( Y page 336). The applicable value can
be found on the wheel or under "Technical
data" ( Y page 360).
iWhen you are driving with the emergency
spare wheel mounted, the tire pressure
monitor cannot function reliably. Only
restart the tire pressure monitor when the
defective wheel has been replaced with a
new wheel. If an emergency spare wheel is mounted,
the system may continue to show the tire
pressure of the wheel that has been
removed for a few minutes. The value dis-
played for the mounted emergency spare
wheel is not the same as the current tire
pressure of the emergency spare wheel.
An emergency spare wheel may also be
mounted against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel.
Replace the tires after six years at the latest, regardless of wear. This also applies to the
emergency spare wheel.

Inflating the collapsible spare wheel
! Inflate the collapsible spare wheel using
the tire inflation compressor before lower-
ing the vehicle. The wheel rim could other-
wise be damaged.
X Pull connector ? and the air hose out of
the housing.
X Remove the cap from the valve on the col-
lapsible spare wheel.
X Screw union nut : on the air hose onto the
valve.
X Make sure on/off switch A of the tire
inflation compressor is set to 0.
X Insert plug ? into the socket of the ciga-
rette lighter ( Y page 284) or into a 12 V
power socket ( Y page 284) in your vehicle.
X Make sure that the SmartKey is in position
1 (Y page 149) in the ignition lock.
X Press on/off switch A on the tire inflation
compressor to I.
The tire inflation compressor is switched
on. The tire is inflated. The tire pressure is
shown on pressure gauge =.
! Do not operate the tire inflation compres-
sor for longer than eight minutes at a time
without a break. It may otherwise overheat.
The tire inflation compressor can be oper-
ated again once it has cooled down.
X Inflate the tire to the specified tire pres-
sure. 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 A on the
electric air pump to 0.
The tire inflation compressor is switched
off.
X Turn the SmartKey to position 0 in the igni-
tion lock.
X If the tire pressure is higher than the speci-
fied pressure, press pressure release but-
ton ; until the correct tire pressure has
been reached.
X Unscrew union nut : on the air hose from
the valve.
X Screw the cap onto the valve of the col-
lapsible spare wheel again.
X Stow plug ? and the air hose in the lower
section of the blower housing.
X Stow the tire inflation compressor in the
vehicle.
Stowing a used collapsible spare wheel
Take the following steps to stow a used col-
lapsible spare wheel. Otherwise, the collaps-
ible spare wheel will not fit in the spare wheel
well. Mercedes-Benz recommends that you
have this work carried out at a qualified spe-
cialist workshop.
! Only place the collapsible spare wheel in
the vehicle when it is dry. Otherwise, mois-
ture may get into the vehicle.
X Remove the valve extractor from the vehi-
cle tool kit.
X Unscrew the valve cap from the valve.
X Unscrew the valve insert from the valve and
release the air.
iFully deflating the tires can take a few
minutes.
X Screw the valve insert back into the valve.
X Screw the valve cap back on.
