Automatic Transmission

Fluid

How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer.

Engine Air Cleaner/Filter

To replace the engine air filter,
release the clamp and remove the
air cleaner outlet duct. Disconnect
the air sensor, unscrew the 3 screws
and remove the filter housing.
To inspect the air cleaner, remove
the element from the air filter
housing and lightly shake it to
release loose dust and dirt.

Engine Coolant

Cooling Liquid Change
The engine cooling system is filled
with a long-life additive (ethylene
glycol), whose properties provide a
proper protection against freezing,
boiling and corrosion.
Coolant Level
Caution
A low coolant level can cause
engine damage.
