Brake fluid change
Brake fluid is hygroscopic, i.e. it absorbs
water. If the brakes become hot, such as
when driving on long downhill stretches,
vapour bubbles can occur in the water,
which can have an extremely adverse
effect on braking power (depending on the
proportion of water).
The fluid change intervals specified in the
Service Booklet must therefore be
observed.
Windscreen wiper
Clear vision is essential for safe driving.
Perform regular checks on the windscreen
wiper and headlight wash system 3 to
ensure they are operating correctly. We
recommend wiper blade replacement at
least once a year.
If the windscreen is dirty, operate the
windscreen wash system before switching
the windscreen wiper on or setting the
wiper to automatic operation with the rain
sensor 3 . This will avoid wiper blade wear.
Do not switch on the windscreen wiper or
set them to automatic operation with the
rain sensor 3 if the windscreen is iced up as
this could damage the wiper blades or the
wiper system.
If the wiper becomes frozen on to the glass,
we recommend that they be released with
the aid of De-icer Spray.
Smearing wiper blades can be cleaned with
a soft cloth and Vauxhall Windscreen
Wash Solvent.
Wiper blades whose lips have become
hardened, cracked or covered with silicone
must be replaced. This may be necessary
as a result of the effects of ice, thawing salt
or heat, or the incorrect use of cleaning
agents.
Switch off the windscreen wipers or
automatic wiper with rain sensor 3 in car
washes, see pages 12, 260.
Windscreen wiper blade maintenance, see
page 262.
