244 Vehicle care
{Warning
Never remove the coolant reservoir
cap when the engine and radiator
are hot. It could cause serious
injury. The engine must be cool
before opening the cap. Carefully
open the cap, relieving the
pressure slowly.
Fill up with a mixture of
demineralised water and anti-freeze
approved for the vehicle. Install the
cap tightly. Have the anti-freeze
concentration checked and have the
cause of the coolant loss remedied
by a repairer.
Note
If the coolant level falls below the
line mark, refill the radiator with
56/44 (Water:56%) mix of
de-mineralized water and organic
acid anti-freeze.
In order to protect your vehicle in
extremely cold weather, use mix of
48 percent water and 52 percent
anti-freeze.
Caution
Plain water or the wrong mixture
can damage the cooling system.
Do not use plain water, alcohol or
methanol anti-freeze in coolant
system.
The engine may overheat or even
catch fire.
Caution
Coolant can be hazardous
material.
Avoid repeated or prolonged
contact with coolant.
Clean your skin and nails with soap
and water after coming in contact
with coolant.
Keep out of reach of children.
Coolant can irritate the skin and
can cause illness or death if
swallowed.
