Emergency spare wheel
Important safety notes
GWARNING
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:
Radapt your driving style accordingly and
drive carefully.
Rnever mount more than one spare wheel or
emergency spare wheel that differs in size.
Ronly use a spare wheel or emergency spare
wheel of a different size briefly.
Rdo not switch ESP®off.
Rhave 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 (
Ypage 291). The value on the wheel is
valid. In addition, the emergency spare wheel
tire pressure can be found under "Technical
data" (
Ypage 332).
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.
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.

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.
XUnscrew the valve cap from the valve.
XUse the back of the valve cap to unscrew
the valve insert from the valve and release
the air.
iFully deflating the tires can take a few
minutes.
XScrew the valve insert back into the valve.
XScrew the valve cap back on.
