Driving Safely with a Trailer•Have the trailer properly serviced and keep it in good condition.
•Make sure that all the weights and load in the vehicle and trailer are within limits.
2Towing Load Limits P. 177
•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
•Securely store all the items in and on the trailer so that they do not shift while
driving.
•Check if the lights and brakes on the trailer are working properly.
•Check the pressures of the trailer tires, including the spare.
•Drive slower than normal.
•Obey posted speed limits for vehicles with trailers.
•Use the
(D position when towing a trailer on level roads.
•Turn more slowly and with a wider turning arc than normal.
•Allow more time and distance for braking.
•Do not brake or turn suddenly.

1Driving Safely with a Trailer
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.

258Maintenance
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 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 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.2Wear Indicators P. 263
•Cracks or other damage around valve stem.
1Checking TiresMeasure 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 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.
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.

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.Tire Size

Handling the Unexpected
If a Tire Goes FlatChanging a Flat TireIf a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe place. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possible to have the full-size tire repaired or
replaced.
1.Park the vehicle on firm, level, non-slippery surface and apply the parking brake.
2.Move the shift lever to
(P.
3.Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).
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.

1.Push the rear edge of the handle on the
front cargo floor lid and open the lid.
2.Take the jack, extension bar, and wheel nut

dealer or a professional towing service.
The subwoofer, a large black enclosure, is located on
the right side under the lid. Do not store anything in
this area. Doing so may compromise vehicle audio

If you replace a flat tire with the spare tire, the low tire pressure/TPMS indicator
comes on while you are driving. After driving for a few miles (kilometers), the
indicator will start blinking for a short time and then stay on. CHECK TPMS
SYSTEM appears on the multi-information display, but this is normal.
If you replace the tire with a specified regular tire, the warning message on the
multi-information display and the TPMS indicator will go off after a few miles
(kilometers).
■Storing the Flat Tire
1Storing the Flat Tire
Always raise the spare tire hoist, even if you are not
stowing a tire. If the hoist is left down, it will be
damaged during driving and need to be replaced.
