Spare wheel
The spare wheel lies in a well under the floor covering of the luggage compartment
and is fixed in place using special screws ⇒fig. 201 .
Before removing the spare wheel, you must take out the box with the vehicle tool
kit box ⇒page 230, fig. 200 .
One should check the inflation pressure in the spare wheel (at best when generally
checking the tyre air pressures - see sign on the fuel filler flap ⇒page 222) to
ensure that the spare wheel is always ready to use.
Temporary spare wheel
A warning label displayed on the rim of the temporary spare wheel indicates that
your vehicle is equipped with a temporary spare wheel.
Please observe the following notes when driving with a temporary spare wheel:
•After fitting on the wheel, the warning stic ker must not be concealed (e.g. by the
wheel trim).
•Do not drive with this spare wheel at more than 80 km/h - risk of accident. Avoid
accelerating at full throttle, sharp braking and fast cornering.
•The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres. The temporary spare wheel R 18 must have an inflation pres-
sure of 420 kPa (4.2 bar)!
•Use this spare wheel only to reach the nearest specialist garage as it is not
intended for continuous use.
•No other summer or winter tyres must be mounted on the rim of the spare
wheel R 18.
Changing a wheel
Preliminary work
The following steps should be carried out before actually changing the
wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from the traffic flow. The place you choose should be level.
–Have all the occupants get out. While changing a wheel, the occu-
pants of the vehicle should not stan d on the road (e.g. behind a crash
barrier).
– Apply the handbrake firmly.
–Engage 1st gear or if your vehicle is fitted with an automatic gearbox,
position the selector lever into position P.
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit ⇒ page 230 and the spare wheel
⇒ page 231 out of the luggage compartment.
WARNING
•If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle on the side of the road at the
prescribed distance from your vehicle while observing all national legal
provisions. In this way you are protecting not only yourself but also other
road users.

Technical Data
256
Vehicle data sticker
The vehicle data sticker ⇒page 255, fig. 231 is located on the floor of the luggage
compartment and is also stated in the Service schedule.
The vehicle data sticker co ntains the following data:
Vehicle identification number (VIN).
Vehicle type.
Gearbox code, paint number, interior equipment number, engine output,
engine code.
Partial description of the vehicle.
7GG - vehicles with DPF ⇒page 186.
Vehicle identification number (VIN)
The vehicle identification num ber - VIN (vehicle body number) is stamped into the
engine compartment on the right hand shoc k absorber dome. This number is also
located on a sign on the lower left hand edge below the windscreen (together with
a VIN bar code).
Engine number
The engine number is stamped into the engine block.
Type plate (production plate)
Is located on the left midd le pillar of the bodywork.
Homologation sign
The homologation sign is located on the lo ck carrier. Vehicles for certain countries
do not have an homologation sign.
Sticker on inside of fuel filler flap
The sticker is affixed to the inside of the fuel filler flap. The sticker contains the
following data:
•The prescribed types of fuel,
•Tyre si z e,
•Tyre pressure.
Fuel consumption according to the regulations
(99/100/EU)
Depending on the range of the special equipment, style of driving, traffic situation,
weather influences and vehi cle condition, the consumption values which in prac-
tice result when using the vehicle ca n deviate from the indicated values.
Urban traffic
The consumption measurement in urban traf fic begins with starting of the cold
engine. Afterwards the normal urban traffic is simulated.
Non-urban traffic
For the consumption measurement in non-ur ban traffic the vehicle, as in daily
motoring, is accelerated and braked several times in all gears. The vehicle speed
changes within the range from 0 to 120 km/h.
Combined traffic
The consumption value in the combined traf fic consists of 37% from the value for
the urban traffic and of 63% from the value for the non-urban traffic.
Note
•Please note that the information stated in the official vehicle registration
documents always takes priority.
