Tyre pressure displayed only after
driving for a few minutes
X Press the reset button on the left of the
multi-function steering wheel
(Y page 242).
The Restart Tyre pressure monitor
Yes Cancel message appears in the multi-
function display.
X Press the æbutton.
The following message appears in the
multi-function display:
Tyre pressure monitor restarted
The tyre pressure monitor has stored the
pressure of the tyres as a new reference
value.
If you wish to cancel the restart:
X Press the çbutton. Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions: for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a torque of 150 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre. Interchange the wheels every 5,000 km to
10,000 km depending on the degree of tyre
wear, provided that the vehicle has the same
size front and rear tyres. Do not reverse the
direction of tyre rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure moni-
tor*.
! On vehicles fitted with a tyre pressure
monitor*, electronic components are loca-
ted in the wheel.
Tyre fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
i Vehicles with a tyre pressure monitor*
If the positions of the wheels on the vehicle
are changed, the tyre pressure may be tem-
porarily displayed at the wrong position.
This is rectified after a few minutes of driv-
ing, and the tyre pressures are displayed
for the correct positions. Operation
* optional

Flat tyre
322The air pump can be operated again once
it has cooled down.
If the tyre pressure is higher than 3.0 bar:
X Version 1: open pressure release
screw 4on the pressure gauge until the
tyre pressure is correct.
X Version 2: press pressure release button
6 until the tyre pressure is correct.
X Switch off the electric air pump with on/off
switch 2, remove from the tyre valve and
stow it away.
Lowering the vehicle X
Place the ratchet ring spanner onto the
hexagon nut of the jack so that the lettering
AB is visible.
X Lower the vehicle by turning the ratchet
ring spanner until the vehicle is once again
standing firmly on the ground.
X Place the jack to one side. 1
–5 Wheel bolts
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted (1 to5). The tightening torque is
150 Nm . G
Risk of accident
Have the tightening torque checked imme-
diately after a wheel is changed. The wheels
could work loose if they are not tightened
to a torque of 150 Nm.
X Turn the jack back to its initial position and
stow it and the rest of the vehicle tool kit in
the luggage compartment. X
Transport the faulty wheel in the boot.
or
X Depending on the size of the wheel, you
may also be able to secure the faulty wheel
in the emergency spare wheel well. In this
case, you will have to remove the stowage
tray from the emergency spare wheel well
and stow it securely in the luggage com-
partment.
i Do not activate the tyre pressure moni-
tor* until the deflated tyre has been
removed from the vehicle. MOExtended run-flat system*
The MOExtended run-flat system must only
be used in conjunction with the tyre pressure
loss warning system*.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 50 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum range that can be driven in
emergency operation is measured from the
point at which the pressure loss warning
message appears in the multi-function dis-
play. Practical advice
