Coolant level
In a closed cooling system, there is hardly
any loss.
If the cooling system is cold, the coolant
should lie above the KALT/COLD mark.
Top up if the level is low.
Top up with anti-freeze. If no anti-freeze is
available, fill with clean tap water or
distilled water. Have the anti-freeze
concentration checked.
Have the cause of coolant loss rectified by
a workshop.
Fit the cap on straight and tighten it.
Brakes
A screeching noise indicates that the brake
lining is at its minimum thickness.
Continued driving is possible. Have the
brake lining replace as soon as possible.
Once new brake lining is fitted, do not brake
unnecessarily hard for the first 200 km.
9 Warning
Allow the engine to cool before opening
the cap. Carefully open the cap,
relieving the overpressure slowly.
Caution
Too low a coolant level can cause
engine damage.
