Emergency spare wheel
Important safety notes
G
WARNING
The wheel or tire size as well as the tire type of the 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 366). The value on the wheel is
valid. In addition, the emergency spare wheel
tire pressure can be found under "Technical
data" (Y page 407).
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.
i When 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. "Minispare" emergency spare wheel/

Always observe the instructions and safety
notes in the "Mounting a wheel" section
(Y page 385). Stowing a used collapsible spare
wheel
! Only place the collapsible spare wheel in
the vehicle when it is dry. Otherwise, mois-
ture may get into the vehicle.
Take the following steps to stow a used col-
lapsible spare wheel. It will not otherwise fit
into the spare wheel well. Mercedes-Benz
recommends that you have this work per-
formed at a qualified specialist workshop, e.g. at an authorized Mercedes-Benz Center.
X Unscrew the valve cap from the valve.
X Use the back of the valve cap to 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 Remove the protective sheet from the vehi-
cle tool kit and pull it over the collapsible
spare wheel.
X Stow the collapsible spare wheel in the
emergency spare wheel well under the
trunk/cargo compartment. 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.
! 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. Emergency spare wheel

described (Y page 384).
The collapsible spare wheel must be moun-
ted before it is inflated.
X Pull connector 0085and the hose out of the
housing.
X Remove the cap from the valve on the col-
lapsible spare wheel.
X Screw union nut 0043of the hose onto the
valve.
X Make sure on/off switch 0083of the tire
inflation compressor is set to 0.
X Insert connector 0085into a 12 V socket
(Y page 314) in your vehicle.
X Turn the SmartKey to position 1in the igni-
tion lock (Y page 157).
X Press on/off switch 0083on 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 0087.
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 0083on the
electric air pump to 0.
The tire inflation compressor is switched
off.
X Turn the SmartKey to position 0in the igni-
tion lock.
X If the tire pressure is higher than the speci-
fied pressure, press pressure release valve button
0044until the correct tire pressure has
been reached.
X Unscrew air hose union nut 0043from the
valve.
X Screw the cap onto the valve of the col-
lapsible spare wheel again.
