1Driving Safely with a Trailer
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.1Towing Speeds and Gears
When towing a fixed-sided trailer (e.g., camper), do
not exceed 55 mph (88 km/h).
At higher speeds, the trailer ma y sway or affect
vehicle handling.

Driving
Lane Keeping Assist System (LKAS)
*
Provides steering input to help keep the vehicle in the middle of a detected lane and
provides audible and visual alerts if the vehicle is detected drifting out of its lane.
1Lane Keeping Assist System (LKAS)
*
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicle control. The system does
not work if you take your hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display (MID) Warning
and Information Messages P. 96
Do not place an object on the top of the instrument
panel. It may reflect onto the windshield and prevent
the system from detecting lane lines properly.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly under the following
conditions:•Your tires are over or under inflated.•Your tires or wheels are of varied size or
construction.•Your vehicle’s suspension has been altered,
changing the height of the vehicle.•Your vehicle has heavy load in the trunk or on the
rear seats.•A compact spare tire
* is mounted.
•Driving on snowy or wet roads.•Roadway lane markers are difficult to see due to
weather (rain, snow, fog, etc.) or road conditions.•Driving on a road with temporary lane markings.•Multiple or varied lane markings are visible on the
pavement due to road repairs or old lane markings.•Roadway objects or structures are misinterpreted
as lane markers.•On non-freeway roadways and on freeways with
many curves.
■Steering input assist
The system applies torque to the
steering to keep the vehicle between
the left and right lane lines. The
applied torque becomes stronger as the
vehicle gets closer to either of the lane
lines.
■Audible and visual alerts
Beeps and a warning display alert
you that the vehicle is drifting out of
a detected lane.
When you operate the turn signals to change lanes, the system is suspended, and
resumes after the signals are off.
If you make a lane change without operating the turn signals, the LKAS alerts
activate, and torque is applied to the steering.

uuWhen Driving uTire Pressure Monitoring System (TPMS)
368Driving
To select the tire pressure monitor, set the power
mode to ON, and roll the multi-function
steering-wheel controls until you see the tire
pressure screen.The pressure for each tire is displayed in psi
(U.S.) or kPa (Canada).
Tire Pressures Low is displayed when a tire
has significantly low pressure. The specific tire
is displayed on the screen.
■
Tire Pressure Monitor
1 Tire Pressure Monitor
The pressure displayed on the MID can be slightly
different from the actual pressure as measured by a
gauge. If there is a significant difference between the
two values, or if the low tire pressure/TPMS indicator
and the message on the MID do not go off after you
have inflated the tire to the specified pressure, have
the system checked by a dealer.
Tire Pressure Monitor Problem may appear if you
drive with the compact spare tire, or there is a
problem with the TPMS.

421Maintenance
Checking and Maintaining TiresChecking 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 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 and 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 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.
• Uneven tread wear. Have a dealer check the wheel alignment.
• Excessive tread wear.2 Wear Indicators P. 426
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been par ked 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 much 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.

WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seri ously hurt or killed.
Follow all instruc tions in this owner’s
manual regarding tire inflation and
maintenance.

1Changing a Flat Tire
*
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model. Do not use them with
another vehicle. Do not use another type of compact
spare tire or wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairing agent on a flat tire,
as it can damage the tire pressure sensor.
