holding clips back in place. Make
sure the under cover is installed
under the edge of the f ront bumper.
The rear dif f erential should be
drained and ref illed with new f luid
according to the maintenance
minder. Have your dealer replace the
rear dif f erential f luid.
Always use Acura ATF-Z1.The transf er assembly f luid should
be drained and ref illed with new f luid
according to the maintenance
minder. Have your dealer replace the
transf er assembly f luid.
If Acura 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.
The transmission should be drained
and ref illed with new f luid according
to the maintenance minder (see page
).
If you are not sure how to check and
add f luid, contact your dealer. UseaSAE90orSAE80W-90

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.
You need to remove the lef t engine
compartment cover to check the
f luid level (see page ).
Check the f luid level in the
reservoirs monthly. There are up to
two reservoirs, depending on the
model. They are:
Brake f luid reservoir (all models)
Clutch f luid reservoir
(manual transmission models
only)
To access the reservoirs, remove the
lef t engine compartment cover (see
page ).
You will also see a ‘‘LOW BRAKE
FLUID’’ message on the multi-
inf ormation display.
Replace the brake f luid every 3 years,
independent of the maintenance
message in the multi-inf ormation
display. 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.
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.

Check these things:
When you turn the ignition switch to
the START (III) position or on
models with keyless access system,
press the engine start/stop button to
set START Mode (see page ),
you do not hear the normal noise of
the engine trying to start. You may
hear a clicking sound, a series of
clicks, or nothing at all.
Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position or on models with keyless
access system, press the engine
start/stop button to set START
Mode (see page ):
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run. You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly. Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, it must be
in Park or neutral.
Turn the ignition switch to the ON
(II) position or on models with
keyless access system, press the
engine start/stop button to set ON
Mode (see page ). Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See

In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to the START (III)
position or on models with keyless
access system, press the engine
start/stop button to set START
Mode (see page ), but the engine
does not run.
Turn the ignition switch to the
START (III) position or on models
with keyless access system, press
the engine start/stop button to set
STARTMode(seepage ).If
the headlights do not dim, check
the condition of the fuses. If the
f uses are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. See
on page .If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
f rom a booster battery (see page
).
Are you using a properly coded
key or keyless access remote (on
models with keyless access
system)? An improperly coded key
or keyless access remote will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).65

Although this seems like a simple
procedure, you should take several
precautions.
You cannot start a vehicle with an
automatic transmission by pushing
or pulling it.Open the hood, and check the
physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or like ice, do not try
jump starting until it thaws.
To jump start your vehicle:
Turn of f all the electrical
accessories: climate control, audio
system, lights, etc. Put the
transmission in neutral (manual)
or Park (automatic), and set the
parking brake. Pull up the battery terminal cover
to remove. The battery terminal
cover can be removed without
removing the lef t side engine
compartment cover.

´´ µStart the vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.
The numbers in the illustration
show you the order to connect the
jumper cables.
Connect one jumper cable to the
positive ( ) terminal on your
battery. Connect the other end to
the positive ( ) terminal on the
booster battery. Once the vehicle is running,
disconnect the negative cable f rom
your vehicle, then f rom the
booster battery. Disconnect the
positive cable f rom your vehicle,
and then from the booster battery.
Install the battery terminal cover.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until everything is
disconnected. Otherwise, you may
cause an electrical short.
Connect the second jumper cable
to the negative ( ) terminal on

If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(seeon
page ).
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator. If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly. Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeon page ).
Start the engine, and set the
interior temperature to maximum
heat (each temperature control
sets to ‘‘ ’’). Add coolant to
the radiator up to the base of the
f iller neck. If you do not have the proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.

Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(seeon page
).
Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
Go to a service station or garage
where you can get technical
assistance. If the charging system indicator
comes on brightly when the engine
is running, the battery is not being
charged.
This indicator should never come on
when the engine is running. If it
starts flashing or stays on, the oil
pressure has dropped very low or
lost pressure. Serious engine
damage is possible, and you should
take immediate action.
You will also see a ‘‘CHECK
ENGINE OIL LEVEL’’ message on
the multi-information display when
this indicator comes on. You will also see a ‘‘CHECK
CHARGING SYSTEM’’ message on
the multi-information display.
Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
