Braking
ABS (Anti-lock Brake System)
212Driving
ABS (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 distribution (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 pedal. This is sometimes referred to as
"stomp and steer."
ABS (Anti-lock Brake System) NOTICE The ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have the
vehicle checked by a dealer immediately.
The ABS does not reduce the time or distance it
takes to stop the vehicle. It only helps with steering
control during hard braking.
In the following cases, your vehicle may need more
stopping distance than a vehicle without ABS:
When driving on rough road surfaces, including twhen driving on uneven surfaces, such as gravel
or snow.
When tire chains are installed. tYou may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.
ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you will 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.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.

Fuel Economy
218Driving
Improving Fuel EconomyFuel economy depends on several conditions, including driving conditions, your
driving habits, the condition of your vehicle, and loading. Depending on these
and other conditions, you may or may not achieve the rated fuel economy of this
vehicle.
Improving Fuel Economy
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more

Maintenance and Fuel Economy
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accordance with the messages displayed on the
multi-information display.
Use the recommended viscosity engine oil, displaying the API Certification Seal. t
Maintain the specified tire pressure. t
Do not load the vehicle with excess cargo. t
Keep your vehicle clean. A buildup of snow or mud on your vehicle's underside t
adds weight and increases wind resistance.

Before Performing Maintenance
222Maintenance
Inspection and MaintenanceFor your safety, perform all listed inspections and maintenance to keep your
vehicle in good condition. If you become aware of any abnormality (noise, smell,
insufficient brake fluid, oil residue on the ground, etc.), have your vehicle inspected
by a dealer. (Note, however, that service at a dealer is not mandatory to keep
your warranties in effect.) Refer to the separate maintenance booklet for detailed
maintenance and inspection information.
Types of Inspection and Maintenance Daily inspections
Perform inspections before long distance trips, when washing the vehicle, or when
refueling. Periodic inspections
Check the automatic transmission fluid level monthly. t

Inspection and Maintenance U.S. models Maintenance, replacement, or repair of
emissions control devices and systems may be
done by any automotive repair establishment
or individuals using parts that are "certified"
to EPA standards.

According to state and federal regulations, failure
to perform maintenance on the maintenance main
items marked with # will not void your emissions
warranties. However, all maintenance services
should be performed in accordance with the
intervals indicated by the multi-information display.

Checking and Maintaining Tires
Maintenance
Checking TiresTo 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 specification’s page for the
specified pressure.
Underinflated tires wear unevenly, 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 hazard,
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 to 2 psi (10 to
20 kPa, 0.1 to 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 t
cuts, splits, or cracks in the side of the tire. Replace it if you see fabric or cord.
Remove any foreign objects and inspect for air leaks. t
Uneven tread wear. Have your dealer check the wheel alignment. t
Excessive tread wear. t

WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash
in which you can be seriously hurt or
killed.
Follow all instructions in this owner’s
manual regarding tire inflation and
maintenance. Checking 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 release air until the specified
pressure is reached.
If checked when hot, tire pressure can be as mush
as 4 – 6 psi (30 – 40 kPa, 0.3– 0.4 kgf/cm
2) higher
than if checked when cold.
Have a dealer check the tires if you feel a consistent
vibration while driving. New tires and any that have
been removed and reinstalled should be properly
balanced.

Checking and Maintaining Tires
Wear Indicators
264Maintenance
Tire Service LifeThe 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 when 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, regardless of their condition or state of
wear.
Checking TiresHigh 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 118 mph or
190 km/h), adjust the tire pressures as shown below
to avoid excessive heat build up and sudden tire
failure. 6-cylinder models Tire Size P235/45R18 94V
Pressure 35 psi (240 kPa, 2.4 kgf/cm
2)
4-cylinder models Tire Size P225/50R17 93V
Pressure 35 psi (240 kPa, 2.4 kgf/cm
2)
If you do not, excessive heat can build up and cause
sudden tire failure.
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 exposed, replace the
tire. Worn out tires have poor traction on
wet roads.

Maintenance
Tire and Wheel Replacement
Tire and Wheel Replacement
Replace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause the ABS and VSA
® (vehicle stability assist)
system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
If you replace a wheel, only use TPMS specified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.
WARNING
Installing improper tires on your vehicle
can affect handling and stability. This can
cause a crash in which you can be seriously
hurt or killed.
Always use the size and type of tires
recommended in this owner’s manual.
