engine compartment.
Do not smoke, cause sparks or expose
●
an open flame to fuel. Fuel fumes are
flammable.
Take care because brake fluid can
●
harm your hands or eyes and damage
painted surfaces. If fluid gets on your
hands or in your eyes, flush the
affected area with clean water imme-
diately.
If you still experience discomfort, con-
sult a doctor.
When working near the electric cool-
■
ing fan or radiator grille

If the fluid level is low or high

It is normal for the brake fluid level to go
down slightly as the brake pads wear or
when the fluid level in the accumulator is
high.
If the reservoir needs frequent refilling, it
may indicate a serious problem.
