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 you rdriving 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
emergency 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
necessary (Y page 311). The applicable value
4 Use of snow chains is not permitted .Observe the notes in the "Snow chains" section. Emergency spare wheel

is found on the wheel or under "Technical
data" (
Ypage 343).
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
emergency 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 collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning
system/the tire pressure monitor when the
damaged wheel has been replaced with a
new wheel.
Vehicles with tire pressur emonitor:
after mounting an emergency spare wheel,
the system may still display the tire
pressure of the removed wheel for a few
minutes .The value displayed for the
mounted emergency spare wheel is not the
same as the current tire pressure of the
emergency spare wheel. Removing the emergency spare wheel
Example
The collapsible spare wheel can be found in
the stowage well under the trunk floor. X
Turn retaining screw 0004counter-clockwise
and remove it.
X Remove collapsible spare wheel 0003. AMG vehicles
