incorrect wheel and tyre dimensions
The wheel or tyre size and the tyre type of the

Wheels and tyres

To prevent hazardous situations:

Drive carefully. 
Never Nt mor e than one emergency
spare wheel or spare wheel that diMers
in size. 
Only use an emergency spare wheel or
spar
e wheel brieOy. 
Do not deactivate ESP n
. 
Have the emergency spare wheel or
spar

e wheel of a diMerent size replaced
at the nearest qualiNed specialist work-
shop. The new wheel must have the cor-
rect dimensions. The collapsible spare wheel is an emergency
spar

e wheel which is only suitable for use for a
limited period of time and in a restricted manner
in the event of a Oat tyre (e.g. until the nearest
workshop).
The tyre sidewalls are folded when in transport
mode. Before use, the collapsible spare wheel has
to be inOated with the accompanying compressor. Check the tyre pressure of the collapsible spare
wheel once
Ntt

ed. Correct the pressure as neces-
sary.
The maximum permissible speed with a collapsi-
ble spare wheel Ntted is 80 km/h.
Do not Nt the collapsible spare wheel with snow
chains.
Replace the collapsible spare wheel aser six years
at the latest, regardless of wear.
% Vehicles with a tyre pressure monitoring sys-
t
em: if a collapsible spare wheel is Ntted the
tyre pressure monitoring system cannot func-
tion reliably. For a few minutes aser an emer-
gency spare wheel is Ntted, the system may
still display the tyre pressure of the removed
wheel. Only restart the system again when the
collapsible spare wheel has been replaced
with a new wheel.
Be sure to also observe the following further rela-
t
ed subjects:

WARNING Risk of injur
y or death due to
an unsecured collapsible spare wheel
If the collapsible spare wheel is not secured
cor
rectly, it can slip, tip over or be thrown
around.
This can seriously injure vehicle occupants. 
Always store the collapsible spare wheel
in t

he emergency spare wheel bag and
attach it to the bracket in the load com-
partment. 
Always ensure that the lashing straps on
t

he emergency spare wheel bag are
safely secured on the rear tie-down eyes
on the load compartment Ooor. Depending on the vehicle's equipment, the col-
lapsible spar

e wheel is located in an emergency
spare wheel bag on a bracket in the load compart-
ment. The collapsible spare wheel in the emer-
gency spare wheel bag and the bracket are lashed
with straps and secured using the rear tie-down
eyes on the load compartment Ooor. Wheels and tyres

improper operation of two-way radios
If you use two-way radios in the vehicle
im
properly, their electromagnetic radiation
can disrupt the vehicle's electronics. This is
the case in the following situations, in particu-
lar:
= The two-way radio is not connected to an
exterior aerial.
= The exterior aerial is Ntted incorrectly or is
not a low-reOection aerial.
This could jeopardise the operating safety of
the vehicle. 
Have the lo
