Brake fluid
Brake fluid is hy groscopic, i. e. it ab sorbs
water. If the brakes b ecome hot, suc h as
when d riv ing on long downhill stretches,
vap our bubb les can occur in the w ater,
which can have an extrem ely adverse
effect on braking power (depending on the
proportion of w ater).
The fluid change intervals specified in the
Service Booklet m ust therefore be
observed.
We recom mend that y ou ha ve brake
fluid changed by a Va ux ha ll Authorised
Repairer, who will be familiar with the
requirements of the law as regards
disposal of brake fluid and can thus help
to protect the environment and your
health.

Windscre en wiper
Clea r vision is essential for safe driv ing.
The cleaning effect of the windscreen wiper
and the windscreen washing sy stem 3
should therefore be checked at regular
intervals. We recommend repla cing the
wiper b la des at least once a yea r.
If the windscreen is dirty, operate the
screen wash before switching on the
wind screen wiper or setting the w iper to
autom atic opera tion w ith the rain sensor 3 .
This will av oid wiper blade wear.
Do not switch on the wind screen wiper or
set them to automa tic operation with the
ra in sensor 3 if the windscreen is iced up as
this could dama ge the wiper b la des or the
wiper system .
If the wiper bec om es frozen on to the glass,
we rec om mend that they be released with
the aid of Vauxhall De-icer Spray .
S mearing wiper blades c an be cleaned with
a soft c loth and Vauxhall Clea ning S olv ent
and Anti-Freez e.
Wiper blades whose lips have become
hardened, crack ed or covered with silicone
must be replac ed. This may be necessary
as a result of the effects of ic e, thawing salt
or hea t, or the incorrect use of cleaning
agents.
