Check diesel fuel filter at shorter intervals if
th e v ehicle is subjecte d to e xtrem e
operating conditions such as high humidity
(primarily in coastal areas), extrem ely high
or low outside temperatures and
sub stantially varying daytim e a nd nig ht-
time temperatures.
If there is water in the diesel fuel filter,
control indica tor N illuminates in the
instrument c luster - see page 69. Dra in the

Coo la nt
During operation, the system is
pres surize d. The tempe rature ma y
the refore ris e to over 100 °C.
The anti-fre ez e provid es ex celle nt
corrosion protection for the cooling and
heating system, as well as freeze
protection down to -28 °C.
Certain types of anti-freeze can lead to
engine d amage . W e the refore strongly
recommend the use of anti-freeze that has
been approved by Vauxhall.
Anti-freeze and corrosion protection
Before the sta rt of the cold weather season,
have the coolant checked for correct
concentration by a workshop. The amount
of anti-freeze must provide protection
down to a pprox. –28 °C. If the anti-freeze
concentration is too low , this reduces
protection from freezing and corrosion.
Top up anti-freeze if necessary.
If c oolant loss is topped up with
demineralised water, ha ve anti-freeze
concentration checked and more anti-
freeze added as necessary.
9 Warning
Anti-freeze is a danger to health: it must
therefore be k ept in the original conta iner
and out of the reach of children.
