264 Self-help
– Screw in the mounting pin (provided in the vehicle's tool
kit) by hand in place of the wheel bolt ⇒ page 263,
fig. 246.
– Then unscrew the other wheel bolts as described above.
– Take off the wheel. The mounting pin stays where it is.
Putting on the spare wheel
– Put on the spare wheel, using the mounting pin to guide
it into place.
– Screw in the wheel bolts and tighten them lightly using
the hexagonal opening in the screwdriver handle.
– Then unscrew the mounting pin and tighten the
remaining wheel bolt lightly.
– Carry out the steps required after you have changed the
wheel ⇒ page 261, "After changing a wheel".
The wheel bolts should be clean and turn easily. Before putting on
the spare wheel, inspect the condition of the wheel and hub
mounting surfaces. These surfaces must be clean before mounting
the wheel.
The wheel bolts are easier to remove from the wheel rim if you use
the hexagonal socket in the screwdriver handle. The reversible
screwdriver blade should be removed as a precautionary measure
when the tool is used for this purpose.
Note the direction of rotation when putting on a tyre with direc-
tional tread pattern ⇒ page 264.
Note
Do not use the hexagonal socket in the screwdriver handle to loosen
or tighten the wheel bolts.
Tyres with directional tread pattern
Tyres with directional tread pattern must be mounted so
that they rotate in the correct direction.
A directional tread pattern is identified by arrows on the sidewall
pointing in the forward running direction. Always note the direction
of rotation indicated when mounting the wheel. This is important so
that these tyres can give maximum grip and avoid excessive noise,
tread wear and aquaplaning.
Drive carefully should you ever have a puncture and have to mount
the spare wheel so it rotates in the wrong direction. This is because
the tyre will not give optimum performance. Bear this in mind
particularly when driving on wet roads.
To benefit from the advantages of tyres with this type of tread
pattern, the defective tyre should be replaced and refitted as soon
as possible so that all tyres again rotate in the correct direction.
Applies to vehicles: with anti-theft wheel bolts
