NOTE:
●Independent of the Maintenance Midner information, replace
the brake fluid every 3 years.●Inspect idle speed every 160,000 miles (256,000 km).●Adjust the valves during services A, B, 1, 2, or 3 if they are
noisy.Symbol Maintenance Sub Items

●Rotate tires
2●Replace air cleaner element
If you drive in dusty conditions, replace every 15,000
miles (24,000 km).●Replace dust and pollen filter
If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from
diesel-powered vehicles, replace every 15,000 miles
(24,000 km).●Inspect drive belt
3●Replace transmission and transfer fluid
4●Replace spark plugs●Replace timing belt and inspect water pump
If you drive regularly in very high temperatures (over
110°F, 43°C), in very low temperatures (under－20°F,－
29°C), or towing a trailer, replace every 60,000 miles (U.
S.)/100,000 km (Canada).●Inspect valve clearance
5●Replace engine coolant
6●Replace rear differential fluid
Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000
km), then every 15,000 miles (24,000 km).

3. Remove the blade from its holder
by grabbing the tabbed end of the
blade. Pull firmly until the tabs
come out of the holder.
4. Examine the new wiper blades. If
they have no plastic or metal
reinforcement along the back
edge, remove the metal
reinforcement strips from the old
wiper blade, and install them in the
slots along the edge of the new
blade.5. Slide the new wiper blade into the
holder until the tabs lock.
6. Slide the wiper blade assembly
onto the wiper arm. Make sure it
locks in place.
7. Lower the wiper arm against the
window.
Windshield: Lower the passenger's
side first, then the driver's side.

Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
Have your dealer check the tires if
you feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comfort and tire life. For best results,
have the installer perform a dynamic
balance.Improper wheel weights can damage
your vehicle's aluminum wheels. Use
only Acura wheel weights for
balancing.Tire Rotation
To help increase tire life 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.Replacing Tires and Wheels
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 different
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
The ABS works by comparing the
speed of the wheels. When replacing
tires, use the same size originally
supplied with the vehicle. Tire size
and construction can affect wheel
speed and may cause the system to
activate.

The brake system
indicator normally
comes on when you turn the ignition
switch to the ON (II) position, and as
a reminder to check the parking
brake. It will stay on if you do not
fully release the parking brake.
If the brake system indicator comes
on while driving, the brake fluid level
is probably low. Press lightly on the
brake pedal to see if it feels normal. If
it does, check the brake fluid level
the next time you stop at a service
station (see page 525).
You will also see a‘‘LOW BRAKE
FLUID’’message on the multi-
information display (see page 87).If the fluid level is low, take your
vehicle to a dealer, and have the
brake system inspected for leaks or
worn brake pads.
However, if the brake pedal does not
feel normal, you should take
immediate action. A problem in one
part of the system's dual circuit
design will still give you braking at
two wheels. You will feel the brake
pedal go down much farther before
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
You will also see a‘‘CHECK BRAKE
SYSTEM’’message on the multi-
information display (see page 87).Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (seeEmergency
Towingon page 572).
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.

The vehicle's fuses are located in
four fuse boxes.
The interior fuse box is underneath
the dashboard on the driver's side.
To remove the fuse box lid, put your
finger in the notch on the lid, pull it
toward you, and take it out of its
hinges.
The rear fuse box is located at the
left side of the cargo area.
The primary under-hood fuse box is
located next to the battery.
To open it, push the tabs as shown.

passenger's side.
To open it, push the tabs as shown.Checking and Replacing Fuses
If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse.
Determine from the chart on pages
569, 570, and 571, or the diagram on
the fuse box lid, which fuse or fuses
control that device. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is
the cause. Replace any blown fuses,
and check if the device works.
1. Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are off.
2. Remove the cover from the fuse
box.
