Wheels and tyres
Tyre service life
The service life of tyres is dependent on tyre pressure, driv-
ing style and fitting.
Fig. 190 Tyre tread wear
indicators
Fig. 191 Diagram for
changing wheels Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 190, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries

.
Tyre pressure
Under-inflation or over-inflation will reduce the life of the tyres considerably
and also impair the vehicle's handling. The inflation pressures are listed on
a sticker on the inside of the fuel tank flap.
Correct inflation pressures are very important, especially at high speeds.
The pressure should therefore be checked at least once a month and before
starting any long journey.
Tyre pressure monitoring (RKA+)*
Monitoring of the tyre pressures is based on the tyre pressures you have
stored. The tyre pressure monitoring system cannot function as intended if
you store tyre pressure settings for a normal load, but then drive with the
vehicle fully laden. The tyre pressure must be adapted to the actual load
and stored accordingly in the tyre pressure monitoring system ⇒ page 251.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ Fig. 191. All the tyres will then last
for about the same time. 

Jump leads
Jump leads must comply with standard DIN 72553 (see manufacturer's doc-
umentation). The wire cross section must be at least 25 mm 2
for petrol en-
gines and at least 35 mm 2
for diesel engines.
Note
● The vehicles must not touch each other, otherwise electricity could flow
as soon as the positive terminals are connected.
● The discharged battery must be properly connected to the vehicle elec-
trical system. 

Jump lead terminal connections
1. Switch off the ignition of both vehicles ⇒ 
.
2. For vehicles without Start-Stop system :
– Connect one end of the red jump lead to the positive +
termi-
nal of the vehicle with the flat battery A ⇒ Fig. 244.
– Connect the other end of the red jump lead to the positive ter-
minal +
in the vehicle providing assistance B.
– Connect one end of the black jump lead to the negative terminal
–
of the vehicle providing assistance B ⇒ Fig. 244.
– Connect the other end of the black jump lead X
to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. However, connect it to
a point as far as possible from the battery A

Engine specifications Checking fluid levels
From time to time, the levels of the different fluids in the ve-
hicle must be checked. Never fill with incorrect fluids, other-
wise serious damage to the engine may be caused.
