Cleaning the Seat BeltsIf your seat belts get dirty, use a soft
brush with a mixture of mild soap
and warm water to clean them. Do
not use bleach, dye, or cleaning
solvents. Let the belts air-dry before
you use the vehicle.
Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.Floor Mats
The driver's and front passenger's
floor mats that came with your
vehicle hook over the floor mat
anchors. To lock each anchor, turn
the knob clockwise. This keeps the
floor mats from sliding forward
(possibly interfering with the
pedals), or backwards (making the
front passenger's weight sensors
ineffective). If you remove a floor
mat, make sure to re-anchor it when
you put it back in your vehicle.If you use a non-Acura floor mat,
make sure it fits properly and that it
can be used with the floormat
anchors. Do not put additional floor
mats on top of the anchored mats.

Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 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 left 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.Tire Service Life
The service life of your tires is
dependent on many factors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inflation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use).
In addition to your regular
inspections and inflation pressure
maintenance, it is recommended that
you have annual inspections
performed once the tires reach five
years old. It is also recommended
that all tires, including the spare, be
removed from service after 10 years
from the date of manufacture,
regardless of their condition or state
of wear.
The last four digits of the TIN (tire
identification number) are found on
the sidewall of the tire and indicate
the date of manufacture (See
Tire
Labeling on page484). 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.

Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shift the transmission or start the
engine, your vehicle must be
transported with the front wheels off the
ground.
With the front wheels on the ground,
do not tow the vehicle more than 50
miles (80 km), and keep the speed
below 35 mph (55 km/h).
Trying to lift or tow your vehicle by the
bumpers will cause serious damage.
The bumpers are not designed to
support the vehicle's weight.
The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in the ACCESSORY (I)
position, and make sure the steering
wheel turns freely before you begin
towing.
