Lowering the vehicle
X
Insert the socket wrench into the ratchet
ring spanner and place it on the jackso that
the letters AB are visible.
X
Turn the ratchet ring spanner until the vehi-
cle is once again standing firmly on the
ground.
X
Place the jack to one side.
X
Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated
(: to A ). The tightening torque must be
130 Nm.
G
Risk of accident
Have the tightening torque checked immedi-
ately after a wheel is changed. The wheels
could work loose if they are not tightened to
a torque of 130 Nm.
X
Turn the jack back to its initial position and
store it together with the rest of the vehicle
tool kit in the stowage compartment in the
luggage compartment.

When you are driving with the emergency
spare wheel fitted, the tyre pressure loss
warning system cannot function reliably.
Only restart the tyre pressure loss warning
system when the defectivewheel has been
replaced with a new wheel.
MOExtended tyres (tyres with run-flat
characteristics)
MOExtended tyres (tyres featuring run-flat
characteristics) enable your vehicle to con-
tinue its journey even with a complete loss of
tyre pressure in one or more tyres.
MOExtended tyres may only be used in con-
junction with the activated tyre pressure loss
warning system or with the activated tyre
pressure monitor.
The maximum permissible distance which
can be driven in run-flat mode depends on the
load in the vehicle. It is 80 km if the vehicle
is partially laden and 30 km if fully laden.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyre pressure loss warning
appears in the multifunction display.
You must not exceed a maximum speed of
80 km/h.
G
Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R
when cornering
R
when braking
R
when accelerating rapidly
Adapt your driving style accordingly and avoid
sudden changes in direction and sudden
acceleration, as well as driving over obstacles
(i.e. kerbs, potholes), and driving off-road.
This is particularly the case when the vehicle
is heavily laden.
The maximum permissible distance that can
be driven in run-flat mode depends to a large
extentonthe loads placed on the vehicle. It
can be shorter due to high speeds, a heavy
load, sudden changes in direction, the road
surface condition, outside temperature, etc.,
or further if you drive carefully and conserva-
tively.
Do not continue to drive in run-flat mode if:
R
you hear banging noises.
R
the vehicle starts to shake.
