Remove the dipstick (yellow loop)
f rom the transmission, and wipe it
with a clean cloth.
Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks.The transmission should be drained
andrefilledwithnewfluidwhenthis
service is shown on a maintenance
message in the multi-inf ormation
display.
If youarenotsurehowtoaddfluid,
contact your dealer.
If the level is below the lower
mark, add f luid into the dipstick
hole to bring it to the level
between the upper and lower
marks.
Pour the f luid slowly and caref ully
so you do not spill any. Clean up
any spill immediately; it could
damage components in the engine
compartment.
Always use Honda Genuine
ATF-Z1 (automatic transmission
f luid).
Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
Make sure the rubber cap on the

If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives, and continued use can
cause stiffer shifting. Replace as
soon as it is convenient.
Remove the transmission f iller bolt,
and caref ully f eel inside the bolt hole
with your f inger.
The f luid level should be up to the
edge of the bolt hole. If it is not, add
Honda Manual Transmission Fluid
(MTF) until it starts to run out of the

tighten it securely.
Check the f luid level with the
transmission at normal operating
temperature and the vehicle sitting
on level ground.
The transmission should be drained

Check the f luid level in the
reservoirs monthly. There are up to
two reservoirs, depending on the
model. They are:Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement.
Using any non-Honda brake f luid can
cause corrosion and decrease the lif e
of the system. Have the brake
system f lushed and ref illed with
Honda Heavy Duty Brake Fluid
DOT 3 as soon as possible.
The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage.

To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.
When the tires are rotated, make
sure the air pressures are checked.Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire’s sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
The ABS and VSA system work by
comparing the speed of each wheel.
When replacing tires, use the same
size originally supplied with the
vehicle. Tire size and construction
can af f ect wheel speed and may
cause the system to activate.
It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.

Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:
Follow these precautions:Never exceed 50 mph (80 km/h).
This tire gives a harsher ride and
less traction on some road
surf aces. Use greater caution
while driving. Do not mount snow chains on the
compact spare tire.
Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
samewheel.Thesparetireisnot
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or replaced,
and put it back on your vehicle as
soon as you can.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
Af ter several miles (kilometers)
driving with the spare, this
indicator begins to f lash, then
stays on again. You will also see a

Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ).
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
Saf ely pull to the side of the road.
Put the transmission in neutral
(manual) or Park (automatic), and
set the parking brake. Turn of f all
accessories, and turn on the
hazard warning indicators.
If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
The pointer of the vehicle’s
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
You will also see a ‘‘WATER TEMP
