The windshield wiper blades are different lengths
NOTE
The windshield wiper blades are different
lengths. The blade on the driver’s side is
longer than the one on the passenger side.
Cleaning
Keeping the windshield/rear window and wiper
blades clean helps improve visibility and prolongs
the service life of the wiper blades. Clean the
wiper blades with a stiff-bristle brush and luke-
warm soap solution or car washing detergent.

Refilling coolant
Coolant helps keep the gasoline engine at the
proper operating temperature. The heat transfer-
red from the engine to the coolant can be used
to warm the passenger compartment.
When refilling coolant, follow the instructions on
the package and use the recommended amount
of coolant. Never fill the cooling system with
water only; this could lead to freezing, corrosion
and engine damage.
WARNING
If the engine has been running, the coolant
will be very hot. Allow the engine to cool
before opening the coolant expansion tank. If
this is not possible, open the cap very slowly
to allow pressure to dissipate.
Coolant expansion tank
Unscrew the cover in the bulkhead.
Unscrew the expansion tank cap and add
coolant. The level should not exceed the yel-
low
MAX
marker in the tank.
Put the other components back in place in the
reverse order.
