Controls
Rear Defogger/Heated Door Mirror/Heated
Windshield Button
Press the rear defogger, heated door mirror,
and heated windshield button to defog the
rear window and mirrors, and to deice the
windshield when the power mode is in ON.
The rear defogger, heated door mirrors, and
heated windshield automatically switch off
after 10-30 minutes depending on the outside
temperature.
However, if the outside temperature is 32°F
(0°C) or below, they do not automatically
switch off.
1Rear Defogger/Heated Door Mirror/Heated Windshield Button
NOTICE
When cleaning the inside of the rear window, be
careful not to damage the heating wires and antenna
line.
It is critical to wipe the window from side to side
along the defogger heating wires and antenna line.
This system consumes a lot of power, so turn it off
when the window has been defogged or deiced.
Also, do not use the system for a long time while the
power system is stopped. This may weaken the 12-
volt battery, making it di fficult to turn the power
system on.
When the outside temperature is below 41°F (5°C),
the heated door mirror may activate automatically for
10 minutes when you set the power mode to ON.
When the outside temperat e is below 39°F (4°C) and
the windshield defroster is turned on, the heated
windshield may automatically activate.
The heated windshield deac tivates itself once the
windshield defroster is tu rned off or the outside
temperate reaches 43°F (6°C).

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 handling, tread life, and
comfort. Refer to the driver’s doorjamb labe l or specifications page for the specified
pressure.
Underinflated tires wear unev enly, adversely 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 pressure with a tire gauge.
At least once a month or before long trips , use a gauge to measure the pressure in
all tires. Even tires in g ood 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 tr ead. 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 deal er check the wheel alignment.
• Excessive tread wear.
2 Wear Indicators P. 526
•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.
Check the spare tire pressu re once a month or before
long trips.
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 tire inflation and
maintenance.
