i
The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. The tyre pressure values indica-
ted by a pressure gauge when the vehicle
is at high altitude are higher than those
shown by the on-board computer. In this
case, do not reduce the tyre pressures.
i After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the dis-
play message Tyre Pressure Monitor
Active is shown instead of the tyre pres-
sure display. The tyre pressures are already
being monitored.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the speci-
fied values for monitoring.
In most cases, the tyre pressure monitor will
automatically detect the new reference val-
ues, e.g. if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
i You will find the menu overview on
(Y page 214).
If you wish to define the new reference values
manually:
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions. Also observe the notes in the section on
tyre pressures (Y
page 298).
X Make sure that the key is in position 2in
the ignition lock.
X Press the =or; button to select the
Service menu.
X Press the 9or: button to select
Tyre pressure.
X Press the abutton.
The current pressure in each individual tyre
is displayed, or the following message
appears:
Tyre pressures displayed after
driving a few minutes
X Press the :button.
The following message appears in the
multi-function display:
Use current pressure values as new
reference values
X Press the abutton.
The following message appears in the
multi-function display:

After a few minutes of driving, the current
pressures are adopted as the new monitor-
ing values.
Cancelling the restart X
Press the %button.
or
X Press the 9button to leave the menu.

waves. This may cause the maximum per-
missible water depth to be exceeded.
Failure to observe these notes may result
in damage to the engine, electrical systems
and transmission. Driving abroad
Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 290). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on sides of the road oppo-
site to the country in which the vehicle is reg-
istered, your headlamps must be switched to
symmetrical dipped beam. Oncoming traffic
will be dazzled less.
X Have the headlamps switched over at a
qualified specialist workshop, e. g. a
Mercedes-Benz Service Centre. G
Risk of accident
Remember to set the headlamps back to
asymmetrical dipped beam when you return
to driving on the same side of the road as that
of the country in which your vehicle was reg-
istered. You may otherwise dazzle the oncom-
ing traffic and could cause an accident. Service
ASSYST PLUS service interval display
The ASSYST PLUS service interval display
informs you of the next service due date. The
service due date is shown in the multi-func-
tion display, for example:
Service A due in .. days
Service A due in .. km
Service A due
The letter indicates how much time the work-
shop will require to carry out the service work.
The letters displayed range from Afor a short
service duration to Hfor a long service dura-
tion.
The ASSYST PLUS service interval display
does not take into account any periods of
time during which the battery is disconnec-
ted.
To maintain the time-dependent service
schedule:
X Note down the service due date displayed
before disconnecting the battery.
or
X Subtract the battery disconnection periods
from the service date shown on the display
after reconnecting the battery. Hiding the service message
If the service due date has not yet been
exceeded, the service message disappears
automatically after a few seconds. You can
also hide the service message yourself.
X Press the %button on the multi-func-
tion steering wheel. Service due date exceeded
A display message is shown in the multi-func-
tion display, for example:
Service A due
Service A .. days overdue 306

G
Risk of accident
If the tyre pressure is now lower than 1.3 bar,
the tyre is too badly damaged. Do not drive
any further. Consult a qualified specialist
workshop which 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 purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop.
X If the tyre pressure is still at least 1.3 bar,
correct it (see fuel filler flap for values).
To increase the tyre pressure: switch on
the electric air pump.
To reduce the tyre pressure: open pres-
sure release screw Fon pressure
gauge G.
X Drive to the nearest workshop and have the
tyre changed there.
X Have the TIREFIT kit replaced as soon as
possible at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre. G
Risk of accident
Do not exceed the maximum speed of
80 km/h.
The "max. 80 km/h" label must be affixed in
the driver's field of vision.
The vehicle's handling characteristics may be
affected. H
