GL5 with a viscosity of SAE 90 or
80W-90, and have your dealer
replace the transfer assembly fluid.
Check the f luid level with the
dif f erential at normal operating
temperature and the vehicle sitting
on level ground. Remove the
dif f erential f luid f iller bolt and
washer, 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, slowly add
VTM-4 Dif f erential Fluid until it
starts to run out of the hole.
Always use Honda ATF-Z1
(automatic transmission f luid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can affect the shift quality.
Have the transmission f lushed and
ref illed with Honda ATF-Z1 by
your dealer as soon as it is
convenient.
Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
The transmission should be drained
and ref illed with new f luid according
to the time and distance recommen-

drained and refilled with new fluid
when this service is indicated by a
maintenance message on the
information display.
Always use Hypoid gear oil GL4 or

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.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage.
Check the brake f luid level in the
reservoir monthly.
Replace the brake f luid according to
the time recommendation in the
maintenance minder schedule.

ÎÎIn
Canada, Honda vehicles comply
with the Canadian emission
requirements, as specified in an
agreement with Environme nt
Canada, at the time they are
manufactured.
Your vehicle has a positive
crankcase ventilation system. This
keeps gasses that build up in the
engine’s crankcase from going into
the atmosphere. The positive crankcase
ventilation valve routes
them from the crankcase back to the
intake manifold. They are then
drawn into the engine and burned.
As gasoline evaporates in the fuel
tank, an evaporative emissions
control canister filled with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is off. After
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The onboard refueling vapor
recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister
filled with activated carbon. While
driving, the fuel vapors are drawn
into the engine and burned off.
The
burning of gasoline in your
vehicl e’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx), and hydrocarbons (HC).
Gasoline evaporating from the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
re act to form photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas. The
United States Clean Air Act
sets standards for automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
