Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements.Honda Motor Oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Honda Motor Oil in your vehicle f or
optimum engine protection. Make
sure the API Certif ication Seal says
‘‘For Gasoline Engines.’’
The oil viscosity or weight is
provided on the container’s label.
5W-20 oil is f ormulated f or year-
round protection of your vehicle to
improve cold weather starting and
f uel economy.
Unscrew and remove the engine oil
fill cap on the valve cover. Pour in
the oil slowly and caref ully so you do
not spill any. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment. Reinstall the engine
oil f ill cap, and tighten it securely.
Wait a f ew minutes, and recheck the
oil level on the engine oil dipstick.
Do not f ill above the upper mark; you
could damage the engine. Recommended Engine Oil

Open the hood, and remove the
engine oil f ill cap. Remove the oil
drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.
Your vehicle does not require any oil
additives. Additives may adversely
af f ect the engine or transmission
perf ormance and durability. You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal,
and it is the proper weight. You must
f ollow the oil and f ilter change
intervals shown on the information
display.
Run the engine until it reaches
normal operating temperature,
then shut it off.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
mechanic. Always change the oil and f ilter
according to the maintenance
messages shown on the odometer
and trip meter display. The oil and
f ilter collect contaminants that can
damage your engine if they are not
removed regularly.

The rear differential should be
drained and refilled with new fluid
when this service is indicated by a
maintenance message on the
info rmation display. This service
may be needed more often under
certain driving conditions (see page
).
Always use Honda VTM-4
Dif f erential Fluid, and have your
dealer replace the rear differential
f luid.
Insert the dipstick all the way back
in the transmission.
If the level is below the lower
mark, remove the f ill plug, then
add the f luid into the 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 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. If you are not sure how to add f luid,
contact your dealer. 6.

The transf er assembly should be
drained and ref illed with new f luid
when this service is indicated by a
maintenance message on the
inf ormation display.
Always use Hypoid gear oil GL4 or
GL5 with a viscosity of SAE 90 or
80W-90, and have your dealer
replace the transfer assembly fluid.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.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage. 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. 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.
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.

A non-Honda floor mat may not fit
your vehicle properly. This could
prevent the proper operation of the
folding rear seats and the passenger’s
seat weight sensors. We recommend
using genuine Honda floor mats. Do
not put additional floor mats on top
of the anchored mats. This
filter removes the dust and
pollenthatisbroughtinfromthe
outside through the heating and
cooling system/climate control
system.
Have your dealer replace this filter
when this service is indicated by a
maintenance message on the
info rmation display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the air flow
from the heating and cooling
system/climate control system
becomeslessthanusual. Check
the condition of the wiper
blades at least every six months.
Replace them if you find signs of
cracking in the rubber, areas that are
getting hard, or if they leave streaks
and unwiped areas when used.
To replace a wiper blade: To raise the wiper arm, turn the
ignition switch to the ON (II)
position and activate the wipers
(see page ). When the wipers
are in the upright position, turn
the ignition switch off to stop the
wipers in that position.

In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
Have your dealer check the tires if
you f eel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed f rom the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comf ort and tire lif e. For best results,
have the installer perform a dynamic
balance.
Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a
band 1/2 inch (12.7 mm) wide band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
lef t on the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators. To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the information display. Move the
tires to the positions shown in the
diagram each time they are rotated.
If you purchase directional tires,
rotate only front-to-back.

If additional battery maintenance is
needed, see your dealer or a
qualif ied technician.
Battery posts,
terminals, and related accessories
contain lead and lead compounds. If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.
Check the terminals f or corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it of f with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
f uture corrosion.

The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.

If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics for the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If
this indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle’s performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damag e.
If you have recently refueled your
vehicle, the indicator could come on
due to a loose or missing fuel fill cap.
You will also see a ‘‘TIGHTEN FUEL
CAP’’ message on the information
display. Tighten the cap until it clicks
at least once. Tightening the cap will
not turn the indicator turn off
imme diately; it can take several days
of norm al driving. The
indicator may also come on with
the ‘‘D’’ indicator. If
the battery in your vehicle has
been disconnected or gone dead,
these codes are erased. It can take
several days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malfunction indicator lamp will
come on for 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Ref er to for more
inf ormation (see page ). 310

If you keep driving with the
malf unction indicator lamp on, you can
damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

If the driver’s power window fuse is
removed, the AUTO function of the
driver’s window will be disabled. To
reset the AUTO function, see page
.
If
you cannot drive the vehicle
wi thout fixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
from one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accesso ry
power socket or radio).
If you replace the blown fuse with a
spare fuse that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
fuse with one of the correct rating as
soon as you can.
Look
for a blown wire inside the
fuse.Ifitisblown,replacethefuse
