When driving
■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect
the ability of the sensor to correctly detect obstacles. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on the sensor.
• The sensor is frozen.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
● The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle
• Objects just under the bumper
• Objects very close to your vehicle
• A person near the vehicle (depending on the type of clothes worn)

214 2-4. Using other driving systems
■When to contact your Toyota dealer
In the following cases, have your Toyota dealer check the system.
●When the bumper is damaged.
● When the indicator is continuously on.
■ Certification (Canada only)
This ISM device complies with Canadian ICES-001.
CAUTION
■Caution when using the Intuitive parking assist
●The Intuitive parking assist is intended as an aid to assist you to park and
is not a substitute for your persona l judgment. Make your driving decisions
based on your observations.
● Do not attach accessories or other objects to the vehicle within the sensor
perceptible area. Doing so may cause the system to malfunction, which
might result in an accident.
● In certain situations, the system will not function properly and when the
vehicle approaches certain objects, the system will not detect those
objects. Therefore, always observe the area around the vehicle and do not
rely solely on the system.
NOTICE
■ Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

416 3-7. Other interior features
■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 trip information display.)
● 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.
NOTICE
■To avoid a compass malfunctions
Do not place magnets or any metal objects near the roof of the vehicle.
Doing this may cause a malfunction of the compass sensor.
■ To ensure normal operation of the compass
●Do not perform circling calibration of the compass in a place where the
earth's magnetic field is subject to interference by artificial magnetic fields.
● During calibration, do not operate electric systems (moon roof, power win-
dows, etc.) as they may interfere with the calibration.

5-1. Essential information
Event data recorder
In a crash or a near car crash eventThe SRS airbag sensor assembly contains the EDR. In a crash or a
near car crash event, this device may record some or all of the follow-
ing information:
● Engine speed
● Whether the brake pedal was applied or not
● Vehicle speed
● To what extent the accelerator pedal was depressed
● Position of the transmission shift lever
● Whether the driver and front passenger wore seat belts or not
● Driver's seat position
● SRS airbag deployment data
● SRS airbag system diagnostic data
● Front passenger's occupant classification
The information above is intended to be used for the purpose of
improving vehicle safety performan ce. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assi st in driving and maintaining
optimal vehicle performance.
Besides storing data useful for tr oubleshooting, there is an event
data recorder (EDR) that records data in a crash or a near car
crash event.

510 5-2. Steps to take in an emergency
■Front passenger detect ion sensor and passenger seat belt reminder
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■ Changing the engine oil (U.S.A. only)
Make sure to reset the oil change system. ( P. 442)
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing the tire pressure warning reset switch does not turn off the tire
pressure warning light.
■The tire pressure warning light ma y turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (after several minutes).
■When a tire is replaced with a sp are tire (vehicles without run-flat
tires)
The compact spare tire is not equipped with the tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire is replaced with the spare tire.
Replace the spare tire with the repair ed tire and adjust the proper tire
inflation pressure. The ti re pressure warning light will turn off after sev-
eral minutes.
