tyres that do not feature run-flat characteris-  
tics, e.g. winter tyres. A TIREFIT kit can be  
obtained from a qualified specialist work-  
shop.  
MOExtended tyres (tyres with run-flat  
characteristics)  
General notes  
With MOExtended tyres (tyres with run-flat  
characteristics), you can continue to drive  
your vehicle even if there is a total loss of  
pressure in one or more tyres. The affected  
tyre must not show any clearly visible dam-  
age.

WARNING  
G
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.

tion compressor to ON.  
The tyre inflation compressor is switched  
on. The tyre is inflated.  
Do not continue driving. Contact a qualified  
specialist workshop.  
First, tyre sealant is pumped into the tyre.  
The pressure may briefly rise to approx-  
imately 500 kPa (5 bar/73 psi).  
Do not switch off the tyre inflation com- Tyre pressure reached

WARNING  
G
X
Let the tyre inflation compressor run for a  
maximum of ten minutes. The tyre should  
then have attained a pressure of at least  
200 kPa (2.0 bar/29 psi).  
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.  
If a pressure of 200 kPa (2.0 bar/29 psi) has  
been attained after five minutes, see "Tyre  
pressure reached" (Y page 343).  
If a tyre pressure of 200 kPa (2.0 bar/29 psi)  
has not been attained after five minutes, see  
"Tyre pressure not reached" (Y page 343).  
If tyre sealant leaks out, make sure you clean  
the affected area as quickly as possible. It is  
preferable to use clear water.  
If you get tyre sealant on your clothing, have it  
cleaned as soon as possible with perchloro-  
ethylene.  
The maximum permissible speed for a tyre  
sealed with tyre sealant is 80 km/h. The  
upper part of the TIREFIT sticker must be  
affixed to the instrument cluster where it will  
be easily seen by the driver.  
! 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 which contained the TIREFIT kit.

mum possible service life, it must always be  
sufficiently charged.  
R
in vehicles with automatic transmission,  
the transmission is locked in position P  
after disconnecting the battery. The vehi-  
cle is secured against rolling away. You  
can then no longer move the vehicle.  
The battery and the cover of the positive  
terminal clamp must be fitted securely dur-  
ing operation.  
Like other batteries, the vehicle battery may  
discharge over time if you do not use the  
vehicle. In such cases, have the battery dis-  
connected at a qualified specialist workshop.  
You can also charge the battery with a  
charger recommended by Mercedes-Benz.  
For more information, please contact a quali-  
fied specialist workshop.  
Comply with safety precautions and take pro-  
tective measures when handling batteries.  
Have the battery charge checked more fre-  
quently if you use the vehicle mainly for short  
trips or if you leave it standing idle for a  
lengthy period. Consult a qualified specialist  
workshop if you wish to leave your vehicle  
parked up for a long period of time.  
When you park the vehicle, remove the key if  
you do not require any electrical consumers.  
The vehicle will then use very little energy,  
thus conserving battery power.

the non-combusted fuel may damage the catalytic converter.  
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the  
discharged battery has frozen. In this case you may neither jump-start the vehicle nor charge  
the battery. Let the battery thaw first. The service life of a battery that has been thawed may  
be reduced. The starting characteristics may be impaired, especially at low temperatures.  
Have the thawed battery checked at a qualified specialist workshop.  
Jump-starting  
349  
Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged,  
the engine can be jump-started from another vehicle or from a second battery using jump  
leads. Observe the following points:  
R
The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,  
jump-start the vehicle using a second battery or a jump-starting device.  
R
Do not start the engine if the battery is frozen. Let the battery thaw first.  
R
Jump-starting may only be performed using batteries with a nominal voltage of 12 V.  
R
Only use jump leads that are not damaged and have a sufficient cross-section and insulated  
terminal clamps.  
R
Make sure that the two vehicles do not touch.  
Make sure that:  
R
The jump leads are not damaged.  
R
Non-insulated parts of the terminal clamps do not come into contact with other metal parts  
while the jump leads are connected to the battery.  
R
The jump leads cannot come into contact with parts which can move when the engine is  
running, such as the V-belt pulley or the fan.
