Circling calibration
When “CAL” appears on the dis-
play, drive the vehicle at 5 mph
(8 km/h) or less in a circle until a
direction is displayed.
If there is not enough space to
drive in a circle, drive around the
block until the direction is dis-
played.
■Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
●The vehicle is stopped immediately after turning.
● The vehicle is on an inclined surface.
● The vehicle is in a place where the earth’s magnetic field is subject to
interference by artificial magnetic fields (underground car park/parking
lot, under a steel tower, between buildings, roof car park/parking lot, near
an intersection, near a large vehicle, etc.).
● The vehicle has become magnetized.
(There is a magnet or metal object near the inside rear view mirror.)
● The battery has been disconnected.
● A door is open.
CAUTION
■While driving the vehicle
Do not adjust the display. Be sure to adjust the display only when the vehicle
is stopped.
■ When doing the circling calibration
Be sure to secure a wide space, and watch out for people and vehicles in the
neighborhood. Do not violate any local traffic rules while performing circling
calibration.

Maintenance and care
■
Cleaning the inside of the back win dow (vehicles with the back window
defogger)
Do not use glass cleaner to clean the back window, as this may cause dam-
age to the back window defogger heater wires. Use a cloth dampened with
lukewarm water to gently wipe the window clean. Wipe the window in
strokes running parallel to the heater wires.
■ Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year
to maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a
sponge or brush to apply the foam. Rub in overlapping circles. Do not apply
water. Excellent results are obtained when keeping the carpet as dry as pos-
sible.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
Doing so may cause the electrical components etc. to malfunction or catch
fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 116)
Electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or severe injury.

464 4-1. Maintenance and care
NOTICE
■Cleaning detergents
Do not use organic substances such as benzene or gasoline, acidic or alka-
line solutions, dye, bleach or other detergent. Doing so may discolor the
vehicle interior or cause streaks or damage to painted surfaces.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration o\
f
leather surfaces.
●Remove any dust or dirt on leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl or plastic, or that contain wax on the
upholstery, as they may stick to the leather surface if the vehicle interior
heats up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.
■ Cleaning the inside of the back win dow (vehicles with the back window
defogger)
Be careful not to scratch or damage the heater wires.
