Tyre pressures differ depending onvarious options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 215.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 224.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre deflation detection system The tyre deflation detection system
continually checks the rotation speed
of all four tyres.
If a tyre loses pressure the control
indicator w illuminates yellow and a
warning message is displayed in the
Driver Information Centre with
Uplevel-Display. Stop immediately
and check tyre pressure.
Control indicator w 3 97.
System initialisation After tyre pressure correction or
wheel change, the system must be
initiated:
1. Apply electrical parking brake.
2. Press the MENU button to select
the Vehicle Information Menu .3. Turn the adjuster wheel to select
Tire Pressure System .
4. Press the SET/CLR button to
select the reset of the system.
On vehicles with Midlevel- Display, make a longer press on
the SET/CLR button to start the
initialisation of the system.
5. On vehicles with Uplevel-Display, the selection is confirmed by a
pop-up indication. Confirm to start
the initialisation of the system.
Selection and indication can be
different between Midlevel-Display
and Uplevel-Display.

8. Press on/off switch on thecompressor. The tyre is filled withsealant.
9. The compressor pressure gauge briefly indicates up to 6 bar whilst
the sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
10. All of the sealant is pumped into the tyre. Then the tyre is inflated.
11. The prescribed tyre pressure should be obtained within
10 minutes. Tyre pressure
3 224 . When the correct pressure
is obtained, switch off the
compressor by pressing the on/off switch again.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Release excess tyre pressure
using the ] button.
Do not run the compressor longer
than 10 minutes.
12. Push catch on bracket to remove sealant bottle from bracket. Screwthe tyre inflation hose to the free
connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
13. Remove any excess sealant using a cloth.14. Take the label indicatingmaximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
15. Continue driving immediately so that sealant is evenly distributedin the tyre. After driving approx.
6 miles (but no more than
10 minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.
If tyre pressure is more than 1.3 bar , set it to the correct value.
Repeat the procedure until there
is no more loss of pressure.
If the tyre pressure has fallen
below 1.3 bar, the vehicle must
not be used. Seek the assistance
of a workshop.
16. Stow away tyre repair kit in load compartment.
