setting off on a long trip. Please do not forget the spare wheel when checking the tyres.
The tyre inflation pressures for summer tyres are indicated on the inside of the fuel filler flap ⇒page 186, fig. 154. The inflation pressures for winter tyres are 20 kPa (0.2 bar) higher than those for summer tyres ⇒page 189.
The tyre pressure should be at the highest pressure specified for your vehicle at all times.
Always check the inflation pressure of ty res when cold. Do not reduce the higher pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your vehicle is carrying a significantly higher payload.
Driving style
Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-and- tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences when driving which may result in an im balance and which makes themselves felt through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases wear-and- tear on the steering, the suspension and tyres. A wheel must also be rebalanced when a new tyre is fitted and each time a tyre is repaired.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-tear on the tyres but will also has an adverse effect on vehicle safety. Contact your specialist garage if you no tice any unusual tyre wear.
WARNING
•If the inflation pressure is too low, the tyre must perform a greater rolling resistance. At higher speeds the tyre will warm up as a result of this. This can result in tread separation and even a tyre blowout.
•Immediately replace the damaged rims or tyres.
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm high, installed at right angles to the direction of travel. These wear indicators are located at 6 - 8 points depending on the make and are evenly spaced around the circumference of the tyre ⇒fig. 155. Markings on the walls of the tyres through the letters “TWI”, triangular symbols or other symbols identi fy the position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the wear indicators, means that your tyres have reached their legally permissible minimum tread depth.
WARNING
•You must have your tyres replaced with new ones at the latest when the wear indicators have been worn do wn. The legally permissible minimum tread depth should be observed.
•Worn tyres do not provide the necessary adhesion to the road surface at high speeds on wet roads. One could experience “aquaplaning” (uncon- trolled movements of the vehicle - “swimming” on a wet road surface).

Vehicle tool kit
The vehicle tool kit and the lifting jack are stored in a locable plastic box in the spare wheel ⇒fig. 157. There is also space here for the removable ball for the trailer towing device.
The vehicle tool kit contains the following parts (depending on equipment fitted):
•Torx wrench,
•Wheel wrench,
•Hook for pulling off a full wheel trim,
•Towing eye,
•Adapter for the wheel bolts lock.
After using the lifting jack, screw in the arm of the lifting jack fully before placing it back in its stowage area.
WARNING
•The factory-supplied lifting jack is only intended for your model of vehicle. On no account attempt to lift a heavier vehicle or other loads - risk of injury!
•Ensure that the vehicle tool kit is safely attached in the luggage compartment.
Tyre repair kit*
The tyre repair kit is intended for the repair of minor tyre defects. The tyre repair kit contains a compressor, inflation bottle, operating instructions and accessories.
The repair with the tyre repair kit is not at all intended to replace a permanent re pair on the tyre, this repai r only s er v es to reach the next w orks hop. T he re pa ir can be undertaken on the vehicle immediately. Please read the attached instructions carefully before the repair.
The tyre repair kit is locate d in the luggage compartment.
Spare wheel*
The spare wheel is stowed in the spare wheel well in the luggage
compartment below the floor covering.
The spare wheel lies in a well under the luggage compartment floor and is fixed in place along with the vehicle tool kit box using special screws ⇒fig. 158.
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 170) to ensure that the spare wheel is always ready to use.
Unidirectional tyres*
If you have such tyres on your vehicle, please refer to the notes below:

Technical Data216
Vehicle data sticker
The vehicle data sticker ⇒page 215, fig. 185 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 150
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)
The type plate is located in the engine co mpartment at the front on the left hand shock absorber dome.
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.
