Information about Service Resetting the ASSYST PLUS service inter- val display ! If the ASSYST PLUS service interval dis- play has been inadvertently reset, this set- ting can be corrected at a qualified special- ist workshop. Have service work carried out as described in the Service Booklet. This may otherwise lead to increased wear and damage to the major assemblies or the vehicle.
A qualified specialist workshop, e.g. a Mercedes-Benz Service Centre, will reset the ASSYST PLUS service interval display after the service work has been carried out. You can also obtain further information on main- tenance work, for example. Special service requirements The prescribed service interval is based on normal operation of the vehicle. Service work will need to be performed more often if the vehicle is operated under arduous conditions or increased loads, for example: Rregular city driving with frequent intermedi-
ate stops
Rif the vehicle is primarily used to travel
short distances
Rfor frequent operation in mountainous ter-
rain or on poor road surfaces
Rif the engine is often left idling for long peri-
ods
In these or similar operating conditions, have the air filter, engine oil and oil filter, for exam- ple, changed more frequently. The tyres must be checked more frequently if the vehicle is operated under increased loads. Further information can be obtained at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre. Driving abroad An extensive Mercedes-Benz Service network is also available in other countries. The Service Hotline's current telephone numbers

X Press on/off switch = on the tyre inflation
compressor to I. The tyre inflation compressor is switched on. The tyre is inflated.
i First, tyre sealant is pumped into the tyre.
The pressure can briefly rise to approx- imately 500 kPa (5 bar/73 psi). Do not switch off the tyre inflation com- pressor during this phase.
X Let the tyre inflation compressor run for five minutes. The tyre should then have attained a pressure of at least 180 kPa (1.8 bar/26 psi).
If a pressure of 180 kPa (1.8 bar/26 psi) has been attained after five minutes, see (Y page 344). If a pressure of 180 kPa (1.8 bar/26 psi) has not been attained after five minutes, see (Y page 344). i If the tyre sealant leaks out, allow it to dry. It can then be removed like a layer of film. If you get tyre sealant on your clothing, have it cleaned as soon as possible with perchloroethylene.
Tyre pressure not reached If a pressure of 180 kPa (1.8 bar/26 psi) has not been achieved after five minutes: X Switch off the tyre inflation compressor. X Unscrew the filler hose from the valve of
the faulty tyre.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again.
After a maximum of five minutes the tyre pressure must be at least 180 kPa (1.8 bar/ 26 psi). G WARNING If the required tyre pressure is not reached after the specified time, the tyre is too badly damaged. The tyre sealant cannot repair the tyre in this instance. Damaged tyres and a tyre pressure that is too low can significantly impair the vehicle's braking and driving char- acteristics. There is a risk of accident. Do not continue driving. Contact a qualified specialist workshop.
Tyre pressure reached X Switch off the tyre inflation compressor. X Unscrew the filler hose from the valve of
the faulty tyre.
! After use, excess tyre sealant may run out of the filler hose. This could cause stains. Therefore, place the filler hose in the plastic bag that contained the TIREFIT kit.
X Stow the tyre sealant bottle, the tyre infla- tion compressor and the warning triangle.
X Pull away immediately. G WARNING A tyre temporarily sealed with tyre sealant impairs the driving characteristics and is not suitable for higher speeds. There is a risk of accident. You should therefore adapt your driving style accordingly and drive carefully. Do not exceed
the specified maximum speed with a tyre that has been repaired using tyre sealant.
The maximum speed for a tyre sealed with tyre sealant is 80 km/h. The "max. 80 km/h" sticker must be affixed to the instrument clus- ter within the driver's field of vision. X Stop after driving for approximately ten
minutes and check the tyre pressure with the tyre inflation compressor. The tyre pressure must now be at least 130 kPa (1.3 bar/19 psi). G WARNING If the required tyre pressure is not reached after driving for a short period, the tyre is too badly damaged. The tyre sealant cannot repair the tyre in this instance. Damaged tyres and a tyre pressure that is too low can signif- icantly impair the vehicle's braking and driv- ing characteristics. There is a risk of accident. Do not continue driving. Contact a qualified specialist workshop.
