Tighten the wheel bolts until they are fin-
X
ger-tight.
Unscrew the centring pin.

Tighten the last wheel bolt until it is finger-
X
tight.
Lowering the vehicle
Turn the crank of the jack anti-clockwise
X
until the vehicle is once again standing
firmly on the ground.
Place the jack to one side.
X
Tighten the wheel bolts evenly in a cross-
X
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.
Turn the jack back to its initial position and
X
store it together with the rest of the vehicle
tool kit in the stowage well under the boot
floor.

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 defective wheel has been
replaced with a new wheel.
MOExtended run-flat system
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in conjunction with the activated tyre
pressure loss warning system or with the acti-
vated 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:
when cornering
R
when braking
R
when accelerating rapidly
R
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
extent on the 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.
