uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you w ill need to press on the brake pedal very
hard before the ABS activates. However, you may feel the ABS activate immediately
if you are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correc tly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system. While normal
braking will not be affected, there is a possibility that
the ABS will not be opera ting. Have your vehicle
checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lockup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with snow chains*.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while the vehicle
accelerates.
•Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.

Maintenance
Checking and Maintaining Tires
Checking Tires
To safely operate your vehicle, your tires must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■Inflation guidelines
Properly inflated tires provide the best combination of handling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ifications page for the specified pressure.
Under inflated tires wear un evenly, adversely affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride harshly, are more prone to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
At least once a month or before long trips, use a gauge to measure the pressure in all
tires, including the spare. Even tires in good condition can lose 1–2 psi (10–20 kPa,
0.1–0.2 kgf/cm
2) per month.
■Inspection guidelines
Every time you check inflation, also examine the tires and valve stems.
Look for:
• Bumps or bulges on the side or in the tread. Replace the tire if you find any cuts,
splits, or cracks in the si de of the tire. Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have a deal er check the wheel alignment.
• Excessive tread wear.
2 Wear Indicators P. 647
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If
necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as
4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm
2) higher than if
checked when cold.
Whenever tire pressure is adjusted, you must
calibrate the TPMS. 2 TPMS Calibration P. 497
Have a dealer check the tires if you feel a consistent
vibration while driving. Ne w tires and any that have
been removed and reinst alled should be properly
balanced.
Check the spare tire pressu re once a month or before
long trips.
3WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding ti re inflation and
maintenance.

information.
Tire Labeling
The tires that came on your vehicle have a
number of markings. Those you should be
aware of are described as shown.
Whenever tires are replaced, they should be replaced with tires of the same size.

uuChecking and Maintaining Tires uWear Indicators
Maintenance
Wear Indicators
The groove where the wear indicator is
located is 1/16 inch (1.6 mm) shallower than
elsewhere on the tire. If the tread has worn so
that the indicator is ex posed, replace the tire.
Worn out tires have po or traction on wet
roads.
Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pressure, maintenance history, speed, and
environmental conditions (even wh en the tires are not in use).
In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires, including the spare, should be removed from service after 10
years from the date of manufacture, regardle ss of their condition or state of wear.
1Checking Tires
High speed driving
We recommend that you do not drive faster than the
posted speed limits and conditions allow. If you drive
at sustained high speeds (over 99 mph or 160 km/h),
adjust the cold tire pressures as shown below to
avoid excessive heat build up and sudden tire failure.
