Driving Safely with a Trailer
• Have the trailer properly servic ed 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. 454
•When towing more than 3,500 lbs (1,590 kg), use of gasoline with a pump
octane number of 91 or higher is recommended.
u Towing performance can be affected by high altitude, high temperature, or
steep uphill.
• Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the tra iler 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 traile r tires, including the spare.
• Turn off Auto Idle Stop sy stem using Auto Idle Stop OFF button. The trailer
weight can affect your vehicle’s brake effectiveness if Auto Idle Stop is activated
on a hill while towing a trailer.
• Drive slower than normal.
• Obey posted speed limits fo r vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
■Things You Need To Know Before Towing a Trailer
■Towing Speeds and Gears
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 trai ler may sway or affect
vehicle handling.

uuWhen Driving uTire Pressure Monitoring System (TPMS) with Tire Fill Assist
528
Driving
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 Monitor1Tire Pressure Monitor
The pressure displayed on the MID can be slightly
different from the actual pr essure as measured by a
gauge. If there is a signifi cant 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.

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 handlin g, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ifications 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 1–2 psi (10–20
kPa, 0.1–0.2 kgf/cm2) 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. 609
•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.
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.
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.

Handling the Unexpected
If a Tire Goes Flat
Changing a Flat Tire*
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe plac e. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possib le to have the full-size tire repaired or
replaced.
1. Park the vehicle on firm, level, non-slip pery surface and apply the parking brake.
2. Change the gear position to
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF
(LOCK).
1 Changing 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 us e 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 other than the
one provided in the kit that came with your vehicle (if
equipped). If a different agent is used, you may
permanently damage the tire pressure sensor.
