the base of the f iller neck. Add
coolant if it is low.Do not add any rust inhibitors or
other additives to your car’s cooling
system. They may not be compatible
with the coolant or engine compo-
nents.
Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Put the radiator cap back on.
Tighten it f ully.
Pourthecoolantslowlyand
caref ully so you do not spill. Clean
up any spills immediately. Spilled
coolant could damage components
in the engine compartment.

Check the level in the windshield
washer reservoir at least monthly
during normal usage. In bad weather,
when you use the washers of ten,
check the level every time you stop
for fuel.When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition the blade edges.
The windshield washer reservoir is
located behind the driver’s side
headlight. Check the reservoir’s f luid
level by removing the cap and
looking at the level gauge attached
to the cap. Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
The low washer level indicator will
light when the level is low (see page
).

The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-
dations in the maintenance schedule.
If the level is below the lower
mark, add f luid into the f iller hole
to bring it to the upper mark (On
CVT model, HOT side’s upper
mark).
Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it is not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can affect shift quality. Have
the transmission f lushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.
To thoroughly f lush the transmission,
the technician should drain and ref ill
it with Honda ATF-Z1 (Automatic
Transmission Fluid), then drive the
vehicle a short distance. Do this
three times. Then drain and ref ill the
transmission a f inal time.
Remove the dipstick and check the
f luid level. There are HOT side and
