Tire Inspection
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:●Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions.●Cuts, splits, or cracks in the side of
the tire. Replace the tire if you can
see fabric or cord.●Excessive tread wear.
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 page456).

16. Put on the spare tire. Put thewheel nuts back on finger-tight,
then tighten them in a crisscross
pattern with the wheel nut wrench
until the wheel is firmly against the
hub. Do not try to tighten the
wheel nuts fully.
17. Lower the vehicle to the ground, and remove the jack.
18. Tighten the wheel nuts securely inthe same crisscross pattern. Have
the wheel nut torque checked at
the nearest automotive service
facility.
Tighten the wheel nuts to:
94 lbf·ft (127 N·m, 13 kgf·m)
19. Remove the center cap from the flat tire. 20. Place the flat tire face up under the
hoist.
21. Insert the hoist bracket into the center hole of the flat tire.

Low Oil Pressure Indicator
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.
Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn off
the engine as soon as you can safely get
the vehicle stopped. 1. Safely pull off the road, and shut
off the engine. Turn on the hazard
warning indicators.
2. Let the vehicle sit for a minute. Open the hood, and check the oil
level (see page326).An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
3. If necessary, add oil to bring the level back to the full mark on the
dipstick (see page393).
4. Start the engine, and watch the oil pressure indicator. If it does not go
out within 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
before you can continue driving
(see Emergency Towing on page
446). Charging System Indicator
If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
You will also see a ‘‘CHECK
CHARGING SYSTEM ’’message on
the multi-information display (see
page81).
Immediately turn off 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.
Go to a service station or garage
where you can get technical
assistance.

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 page401).
You will also see a ‘‘LOW BRAKE
FLUID ’’message on the multi-
information display (see page81). 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 page81). 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 (see
Emergency
Towing on page446).
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.

Opening the Fuel Fill Door
ManuallyIf the fuel fill door release button
does not work, use the release lever
inside the rear fuse box lid in the
cargo area.
To open the fuel fill door, pull the
release lever rearward.Emergency Towing
If your vehicle needs to be towed,
call a professional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
The only way you can safely tow
your vehicle is with flat-bed
equipment.
The operator will load
your vehicle on the back of a truck.
Any other method of towing will
damage the drive system. When you
contact the towing agency, inform
them a flat-bed is required.
Towing with only two tires on the
ground will damage parts of the all-
wheel-drive system. Your vehicle should
be transported on a flat-bed truck or
trailer.

If your vehicle gets stuck in sand,
mud, or snow, call a towing service to
pull it out (see the previous page).
For very short distances, such as
freeing the vehicle, you can use the
detachable towing hook that mounts
on the anchors in the front and rear
bumpers.
1. Remove the cover, put cloth on theedge of the cover and carefully pry
with a small flat-tip screwdriver or
a metal fingernail file.
The cover is attached to the bumper
with a tether.

The tires on your vehicle meet all U.
S. Federal Safety Requirements. All
tires are also graded for treadwear,
traction, and temperature
performance according to
Department of Transportation (DOT)
standards. The following explains
these gradings.
Uniform Tire Quality Grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades. Treadwear
The treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions on a specified
government test course. For
example, a tire graded 150 would
wear one and one-half (1 1/2) times
as well on the government course as
a tire graded 100. The relative
performance of tires depends upon
the actual conditions of their use,
however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
Traction
The traction grades, from highest to
lowest, are AA, A, B, and C. Those
grades represent the tire's ability to
stop on wet pavement as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction
performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.DOT Tire Quality Grading (U.S. Vehicles)45408/06/06 16:58:07 09 ACURA MDX MMC North America Owner's M 50 31STX620 enu
