Problem
Possible causes/consequences and
M
MSolutions The transmission has
problems shifting gear. The transmission is losing oil.
X Have the transmission checked at a qualified specialist work-
shop immediately. The acceleration ability
is deteriorating.
The transmission no
longer shifts into all of
the gears.
Reverse gear can no
longer be engaged. The transmission is in emergency mode.
X Stop.
X Shift the transmission to position P.
X Switch off the engine.

Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek immediate medical attention. R
If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always touch the vehicle body before opening the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong 180
RefuellingDriving and parking

Observe the notes on sockets
(Y
page 316).
X Turn the key to position 1in the ignition
lock (Y page 157).
X Press on and off switch ?on the tyre infla-
tion compressor to ON.
The tyre inflation compressor is switched
on. The tyre is inflated.
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-
pressor during this phase.
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).
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.
Tyre pressure not reached If a tyre pressure of 200 kPa (2.0 bar/29 psi)
has not been attained after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
Please note that tyre sealant may leak out
when unscrewing the filler hose.
X Very slowly drive forwards or reverse
approximately 10 m.
X Pump up the tyre again.
After a maximum of ten minutes, the tyre
pressure must be at least 200 kPa (2.0 bar/
29 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 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 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. H
Environmental note
Have the used tyre sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
If a tyre pressure of 200 kPa (2.0 bar/29 psi)
has been attained after ten minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre. Flat tyre
