Practical advice
Flat tyre
Lowering the vehicle
왘
Turn the crank of the jack anti-clock-
wise until the vehicle is once again
standing firmly on the ground.
왘
Place the jack to one side.
1
to
5
wheel bolts
왘
Tighten the wheel bolts evenly in a
crosswise pattern in sequence
1
to
5
.
왘
Using the tool from the vehicle kit,
tighten the wheel bolts as much as you
can by hand. The tightening torque
must be 150 Nm .
왘
Turn the jack back to the out-of-use po-
sition.
왘
Stow the wheel wrench, centring pin
and jack in the vehicle tool kit in the
boot.
You may only use the MO Extended run-flat
system in conjunction with the tyre pres-
sure loss warning.
!
The maximum distance you may drive in run-
flat mode depends on the load in the vehicle. It is
approximately 50 km if the vehicle is partially
laden and approximately 30 km if fully laden.
The maximum distance to be driven in run-flat
mode begins from the moment the tyre pressure
loss warning appears in the multi-function dis-
play.
You must not exceed a maximum speed of
80 km/h.
i
By using TIREFIT before starting the run-flat
mode, the maximum distance can be increased
considerably. If TIREFIT cannot seal the tyre due
to the type of damage, you may still continue
driving up to the maximum possible distance in
run-flat mode.

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
150 Nm .

Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
앫
when cornering
앫
when braking
앫
when accelerating rapidly
You must therefore adapt your driving style
accordingly and avoid sudden changes in di-
rection or acceleration, as well as driving
over obstacles (kerbs, potholes, off-road).
This is particularly the case when the vehicle
is heavily laden.
The distance that can be driven in run-flat
mode depends to a large extent on the loads
exerted on the vehicle. It can therefore be
much less due to speed, load, driving ma-
noeuvres, road surface condition, outside
temperature, etc. or also greater if you drive
carefully.
