does not have to be checked. If an
unusual noise sounds during steering or the power steering reacts
unusually, seek the assistance of a
workshop.
Washer fluid

suitable quantity of windscreen
washer fluid which contains
antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Brakes
In the event of minimum thickness ofthe brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
