● When there is a parked vehicle behind the target parking spot, it may not be

detected due to the distance. Also, depending on the shape of the vehicle

and other conditions, the detectable range may shorten or detection may

not be possible.

●The system will not operate as it cannot

detect the parking space if there are

objects other than parked vehicles pres-

ent, such as poles and walls.

WARNING

●Do not rely solely upon the Simple Intelligent Parking Assist System. As

with unequipped vehicles, move forward and back up carefully while

directly confirming the safety of your surroundings and the area to the rear

of the vehicle.

●The sensor detection areas and reaction times are limited. When moving

forward or reversing, check the areas surrounding the vehicle (especially

the sides of the vehicle) for safety, and drive slowly, using the brake to

control the vehicle’s speed.

●Drive slowly while adjusting your speed by depressing the brake pedal

when backing up or moving forward.

● If it seems the vehicle may make contact with a pedestrian, another vehi-

cle or any other obstacles, stop the vehicle by depressing the brake pedal,

and then press the S-IPA switch to turn off the system.

●Use the system in a parking lot with a flat surface.

●Observe the following precautions, as the steering wheel automatically

turns during use.

• There is risk of a necktie, scarf, your arm, etc., being caught up in the

steering wheel. Please do not allow your upper body to be close to the

steering wheel. Also, do not allow children close to the steering wheel.

• There is a possibility of injury when the steering wheel turns if you have

long fingernails.

• In case of an emergency, stop the vehicle by depressing the brake

pedal, and then press the S-IPA switch to turn off the system.

● Always confirm that there is appropriate space before attempting to park

the vehicle and operate the system.

WARNING

●Do not use the system in the following situations, as the system may be

unable to correctly assist you in reaching the target parking spot and may

lead to an unexpected accident.

• On sharp bends

• During bad weather such as heavy rain, fog, snow, or a sandstorm

• When the tires slid while attempting to park

• When fallen leaves or snow has accumulated in a parking space

• When items such as a towing bracket, trailer, bicycle carrier, etc., are

installed on the rear of the vehicle

• When a vehicle, where the front/rear end is above the detection area

such as a truck or bus, or vehicle with a towing bracket, trailer, bicycle

carrier, etc., is parked at the front or rear of the parking space

• If the sensor is covered by the front bumper cover, etc.

• If a vehicle or obstacle is not in a suitable position at the front or rear of

the parking space

• In an area that is not a parking lot

• A parking lot that is not paved, such as a sand or gravel parking lot

• A parking lot that has a slope or undulations in the road

• A frozen, snow-covered or slippery road

• The asphalt is melting due to hot weather

• There is an obstacle between the vehicle and the target parking spot

• Using tire chains or compact spare tire (if equipped)

●Do not use tire other than that provided by the manufacturer. The system

may not operate properly. When replacing tires, contact any authorized

Toyota retailer or Toyota authorized repairer, or any reliable repairer.

●The system may not be able position the vehicle in the set location in the

following situations.

• The tires are extremely worn or the tire pressure is low

• The vehicle is carrying very heavy load

• The vehicle is tilted due to having luggage, etc., located on one side of

the vehicle

• There are road heaters installed in the parking lot to prevent the road

surface from freezing.

In any other situations when the set position and vehicle position greatly

differ, have the vehicle inspected by any authorized Toyota retailer or Toy-

ota authorized repairer, or any reliable repairer.

WARNING

● Make sure to observe the following precautions regarding the exit parallel

parking assist mode.

Exit parallel parking assist mode is a function used when departing from a

parallel parking spot. However, this function may not be usable if obsta-

cles or people are detected in front of the vehicle. Only use this function

when departing from a parallel parking spot. In the event that the steering

control operates, either turn the system off using the S-IPA switch or oper-

ate the steering wheel to stop the control.

●If exit parallel parking assist mode is mistakenly used in the following situ-

ations, the vehicle may make contact with an obstacle.

The departure function is operated in a direction where an obstacle is

present, but the obstacle is not detected by the side sensors (situations

such as when the vehicle is directly beside a pole).

●Observe the following precautions, as the sensors may stop functioning

properly which may lead to an accident.

4

• Do not subject the sensor to strong shocks by hitting it, etc. The sen-

sors may not function properly.

• When using a high-pressure washer to wash the vehicle, do not spray

water directly on the sensors. Equipment may not function properly if

subjected to an impact from strong water pressure. If the vehicle

bumper strikes something, equipment may not operate properly due to

a sensor malfunction. Have the vehicle inspected at any authorized

Toyota retailer or Toyota authorized repairer, or any reliable repairer.

4-5. Using the driving support systems

WARNING

● In the following situations, the sensors may not operate normally and may

lead to an accident. Drive carefully.

• Obstacles cannot be detected in the side areas until a scan of the side

areas is completed. (P. 358)

• Even after the scan of the side areas is completed, obstacles such as

other vehicles, people or animals that approach from the sides cannot

be detected.

• The sensor is frozen (if it thaws, the system returns to normal).

A warning message may display at particularly low temperatures due to

the sensor freezing and it may not detect parked vehicles.

• The sensor is blocked by someone’s hand.

• The vehicle is tilted a large amount.

• The temperature is extremely hot or cold.

• The vehicle is driven on undulating roads, slopes, gravel roads, in areas

with tall grass, etc.

• An ultrasonic wave source is nearby, such as the horn or sensors of

another vehicle, a motorcycle engine or the air brake of a large vehicle.

• Heavy rain or a water strikes the vehicle.

• Do not install any accessories within the sensor detection range.

NOTICE

■ When using the S-IPA

●Check that the parking space is suitable. (Width of the space, if there are

any obstacles, road surface condition, etc.)

●S-IPA will not operate properly if the vehicle at the front or back of the

parking space moves, or if an obstacle enters the parking space after the

sensors have detected the parking space. Always check the surrounding

area during parking assist operation.

●The sensors may not be able to detect curbs. The vehicle may drive onto

the curb depending on the situation, such as if a vehicle at the front or

back of the parking space has driven on the curb.

Check the surrounding area to prevent the tires and wheels from being

damaged.

● When reversing, reverse the vehicle

slowly to prevent the front end of the

vehicle from hitting an obstacle in the

4

front of the vehicle.

● When reversing, reverse the vehicle

slowly to prevent the front end of the

vehicle from hitting the vehicle parked in

front of the parking space.

●The vehicle may not be able to be parked at a target parking space if the

vehicle moves forward when the shift lever is in R or reverses when the

shift lever is in a position other than R, such as when parking on a slope.

hill-start assist control systems

● A sound may be heard from the engine compartment when the brake pedal

is depressed repeatedly, when the hybrid system is started or just after the

vehicle begins to move. This sound does not indicate that a malfunction has

occurred in any of these systems.

● Any of the following conditions may occur when the above systems are

operating. None of these indicates that a malfunction has occurred.

• Vibrations may be felt through the vehicle body and steering.

• A motor sound may be heard also after the vehicle comes to a stop.

■ECB operating sound

ECB operating sound may be heard in the following cases, but it does not

indicate that a malfunction has occurred.

● Operating sound heard from the engine compartment when the brake pedal

is operated.

WARNING

■ The ABS does not operate effectively when

●The limits of tire gripping performance have been exceeded (such as

excessively worn tires on a snow covered road).

●The vehicle hydroplanes while driving at high speed on wet or slick road.

■ Stopping distance when the ABS is operating may exceed that of nor-

mal conditions

The ABS is not designed to shorten the vehicle’s stopping distance. Always

maintain a safe distance from the vehicle in front of you, especially in the

following situations:

● When driving on dirt, gravel or snow-covered roads

●When driving with tire chains

●When driving over bumps in the road

● When driving over roads with potholes or uneven surfaces

■ TRC/VSC may not operate effectively when

Directional control and power may not be achievable while driving on slip-

pery road surfaces, even if the TRC/VSC systems is operating.

Drive the vehicle carefully in conditions where stability and power may be

lost.

■ Hill-start assist control does not operate effectively when

●Do not overly rely on hill-start assist control. Hill-start assist control may

not operate effectively on steep inclines and roads covered with ice.

●Unlike the parking brake, hill-start assist control is not intended to hold the

vehicle stationary for an extended period of time. Do not attempt to use

hill-start assist control to hold the vehicle on an incline, as doing so may

lead to an accident.

■ When the VSC is activated

The slip indicator light flashes. Always drive carefully. Reckless driving may

cause an accident. Exercise particular care when the indicator light flashes.
