Driving
When driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press the SET/– button when you reach the de sired speed. The moment you
release the button, the set speed is fixed, and ACC with Low Speed Follow begins.
When driving slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pressing the button fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.
When ACC with Low Speed Follow starts
operating, the vehicle icon, interval bars and
set speed appear on the driver information
interface.
When you use ACC with Low Speed Follow,
Straight Driving Assist (a feature of the Electric
Power Steering system) is activated.
By enabling the steering system to
automatically compensate for natural steering
pull, Straight Driving Assist makes it easier for
you to keep your vehicl e in a straight line.

The system may not properly detect lane markings and the position of your vehicle
under certain conditions. Some examples of these conditions are listed below.
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between la ne lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflected onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.

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 unevenly, advers ely 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. 651
•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. 500
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.

uuChecking and Maintaining Tires uTire Rotation
Maintenance
Tire Rotation
Rotating tires according to the maintena nce messages on the driver information
interface helps to distribute wear more evenly and increase tire life.
■Tires without rotation marks
Rotate the tires as shown here.
■Tires with rotation marksRotate the tires as shown here.
1Tire Rotation
Tires with directional trea d patterns should only be
rotated front to back (not fr om one side to the other).
Directional tires should be mounted with the rotation
indication mark facing forward, as shown below.
Whenever tires are rotated, you must calibrate the
TPMS. 2 TPMS Calibration P. 500
