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. 215
•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 tra iler 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 an d 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.

uuWhen Driving uACC (Adaptive Cruise Control)*
236
Driving
Take your foot off the pedal and press the DECEL/SET button when you reach the
desired speed. The moment you release the DECEL/SET
button, the set speed is fixed, and adaptive
cruise control begins. uA vehicle icon and distance bars appear
on the multi-information display.
■To Set the Vehicle Speed1ACC (Adaptive Cruise Control)*
Do not use ACC under these conditions:•In poor visibility.•In heavy traffic.•When you must slow down and speed up
repeatedly.
•On winding roads.•When you enter a toll gate, interchange, service
area, parking area, etc. In these areas, there is no
vehicle ahead of you, but ACC would still try to
accelerate to your set speed.
•In bad weather (rain, fog, snow, etc.)•On a slippery road (for example a road covered
with ice or snow).
•When a spare tire is installed.•When going down a steep hill where the engine
braking does not work sufficiently.
When not using adaptive cruise control: Turn off
adaptive cruise by pressing the MAIN button.
1To Set the Vehicle Speed
You can switch the displayed set speed
measurements on the multi-information display
between mph and km/h.

uuWhen Driving uTPMS (Tire Pressure Monitoring System)
Driving
TPMS (Tire Pressure Monitoring System)
Monitors the tire pressure while you are driving. If your vehicle’s tire pressure
becomes significantly low, the low tire pressure/TPMS indicator comes on and a
message appears on the mu lti-information display.
To select the tire pressure monitor, turn the
ignition switch to ON
w*1 and press the /
button until you see the tire pressure screen.
If all the tire pressures are normal, TIRE
PRESSURE OK and the pressure of all four
tires will be displayed.
The pressure for each tire is displayed in PSI
(U.S.) or kPa (Canada).
*1: Models with the keyless access system have an ENGINE START/STOP button
instead of an ignition switch.
■Tire Pressure Monitor
1 TPMS (Tire Pressure Monitoring System)
Conditions such as low ambient temperature and
altitude change directly affect tire pressure and can
trigger the low tire pressure / TPMS indicator to come
on. 2 If the Low Tire Pressure/TPMS Indicator
Comes On or Blinks P. 337
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPM S indicator will not come
on as a result of over inflation.
1 Tire Pressure Monitor
The pressure displayed on the multi-information
display 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 multi-information display do not go off after
you have inflated the tire to the specified pressure,
have the system checked by a dealer.
TPMS ERROR may appear if you drive with the
compact spare tire, or ther e is a problem with the
TPMS.

uuWhen Driving uTire Pressure Monitoring System (TPM S) - Required Federal Explanation
Driving
Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diffe rent size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pr essure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

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 comb ination of handling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ification’s page for the specified pressure.
Underinflated tires wear unevenly, adversel y affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, 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 pressu re with a tire gauge.
At least once a month or before long trip s, 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 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. 305
•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
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.
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 instructions in this owner’s
manual regarding tire inflation and
maintenance.
