196 Car care
When changing a wheel, take the tool kit out
first, then the spare wheel.
Changing a wheel
If light-alloy wheels have been fitted to the
car for several years and a change is made
to steel wheels, the threads for the wheel
bolts in the brake discs should be cleaned
before the thinner steel wheels are fitted.
The innermost threads in the holes may be
clogged with sand, salt and rust so that the
correct tightening torque cannot be
achieved.
NOTE
To avoid damaging a punctured alloy
wheel this can be placed outside up in the
spare-wheel well but only while driving to
the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 129.
WARNING
• The car jack is designed solely for use
in changing a wheel or fitting snow
chains. It must not be used to support
the car during repair work or servicing.
• Never crawl under a car that is
supported only by a jack.
• Special care must be taken if the car is
on a slope – use wheel chocks!
• Position chocks, one ahead and one
behind, the wheel that is diagonally
opposite to the one to be changed.
• Switch on the hazard warning lights if
the car is on a road.
• Apply the parking brake and leave the
car in gear (1st or reverse). Automatic
transmission: move selector to the
P position.
• Ensure that everybody is out of the car
before jacking it up.
• Never start the engine while the car is
jacked up.
• The jack must stand on a firm, level
surface.
• Stow the jack in the place provided for
it under the panel in the floor of the
trunk. Secure it properly to avoid injury
to passengers in the event of an acci-
dent.
• Do not use the jack for any purpose
other than for jacking up the car.
