intended path is clear. Use caution just as you would when back ing up any
vehicle.
● The camera has a special lens. Depicted distances between objec ts and
flat surfaces differ from actual distances.
● Always check the vehicle surrounding area, because the guide li nes are
ancillary lines.
● The guide lines are ancillary lines and do not change even if t he steering
wheel is turned.
● Do not use the system if the trunk is open.
■ Conditions which may affect t he rear view monitor system
● If the back of the vehicle has been hit, the camera’s position and mounting
angle may have changed. Have the vehicle inspected by your Toyota

● Rapid temperature changes, such as when hot water is poured on the
vehicle in cold weather, may cause the system to function abnor mally.
● If the camera lens is dirty, it cannot transmit a clear image. Rinse with
water and wipe with a soft cloth. If the camera lens is extreme ly dirty, wash
with a mild cleanser and rinse.
● If the tire size is changed, the area displayed on the screen may change.

Tire chains
Tire chains cannot be used on your vehicle because of the lack of
clearance between the tires and vehicle body.
When tire chains cannot be used, use of another type of tractio n
device (such as spring chains) may be acceptable if use on your vehi-
cle is recommended by the device manufacturer, taking into acco unt
tire size and road conditions.
Follow the device manufacturer's instructions, especially regarding
maximum vehicle speed.
To help avoid damage to your vehicle, drive slowly, readjust or
remove the device if it is contacting your vehicle, and do not spin your
wheels. Damage caused to your veh icle by use of a traction device is
not covered under warranty.
Make certain that any traction device you use is an SAE class “ S”
device, and use it on the rear wheels only.
Always use the utmost care when driving with a traction device. Over-
confidence because you are using a traction device could easily lead
to a serious accident.
Selecting tire chains
We recommend that you consult your Toyota dealer for informatio n
about the chains t hat you can use.

Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as c
uts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consul t with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitt er is not
registered, the tire pressure w arning system will not work prop erly. After
driving for about 20 minutes, t he tire pressure warning light c omes on
after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if they have seldom or never b een used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Low profile tires
Generally, low profile tires will wear more rapidly and tire gr ip perfor-
mance will be reduced on snowy and /or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains on sno wy and/or
icy roads and drive carefully at a speed appropriate for road a nd weather
conditions.
