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/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. 535
•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.

Battery
Checking the Battery
The condition of the battery is monitored by a
sensor located on the negative terminal of the
battery. If there is a problem with this sensor,
the driver information interface will display a
warning message. If this happens, have your
vehicle inspected by a dealer.
Check the battery termin als for corrosion monthly.
To access the battery terminals:
1. Remove the engine compartment cover.
2 Engine Compartment Cover P. 511
2.Remove the clips using a Ph illips-head screwdriver, then remove the air intake
duct.
2 High Beam Headlights P. 521
If your vehicle’s battery is disconnected or goes dead:
•The audio system is disabled.
2 Audio System Theft Protection P. 227
•The clock resets*.

1Battery
WARNING: Battery post, terminals,
and related accessories contain lead
and lead compounds.
Wash your hands after handling.
When you find corrosion, cl ean the battery terminals
by applying a baking powder and water solution.
Clean the terminals with a damp towel. Cloth/towel
dry the battery. Coat the terminals with grease to
help prevent future corrosion.
When replacing the battery, the replacement must be
of the same specifications.
Consult a dealer for more information.
3WARNING
The battery gives off explosive hydrogen
gas during normal operation.
A spark or flame can cause the battery to
explode with enough force to kill or
seriously hurt you.
When conducting any battery
maintenance, wear prot ective clothing and
a face shield, or have a skilled technician do
it.

To ensure proper and safe operation, th e Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.1 Climate Control System Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.
Refrigerant in your vehicle’ s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.

Exterior Care
Dust off the vehicle body after you drive.
Regularly inspect your vehi cle for scratches on painted surfaces. A scratch on a
painted surface can result in body rust. If you find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more frequently when driving in the following
conditions:
• If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
• Fold in the door mirrors.
• For models equipped with automatic inte rmittent wipers, turn the wipers off.
• Make sure to follow the instructions indicated on the automated car wash.
• Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.
• Do not spray water directly onto the ca mera or the area around it. Water may
enter the lens and cause the camera to malfunction.

Accessories
When installing accessories, check the following:
• Do not install accessories on the windsh ield. They can obstruct your view and
delay your reaction to driving conditions.
• Do not install any accessories over areas marked SRS Airbag, on the sides or backs
of the front seats, on front or side pillars, or near the side windows.
Accessories installed in these areas may interfere with proper operation of the
vehicle’s airbags or may be propelled into you or another occupant if the airbags
deploy.
• Be sure electronic accessories do not overload electrical circuits or interfere with
proper operation of your vehicle.
2 Fuses P. 575
•Before installing any electro nic accessory, have the installer contact a dealer for
assistance. If possible, have a deal er inspect the final installation.

Handling the Unexpected
If the Battery Is Dead
Jump Starting Procedure
Turn off the power to electric devices, such as audio and lights. Turn off the engine,
then open the hood. 1.Pull up on the engine compartment cover,
remove it from the pin holders.
2. Remove the holding clip s and the air intake
duct.
3. Pull up on the engine cover, remove it from
the pins.
u Start on the passenger side and lift the
outermost edge of the cover.
u Move towards the driver side while
applying uniform upward pressure.
4. Connect the first jumper cable to your
vehicle’s battery + terminal.
1If the Battery Is Dead
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Be careful
not to tangle the jumper cables or allow the cable
ends to touch each other while attaching or
detaching the jumper cables.
Battery performance degrades in cold conditions and
may prevent the engi ne from starting.
3WARNING
A battery can explode if you do not follow
the correct procedure, seriously injuring
