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.
• 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.

528

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. 461)

• 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.
• The angle of the sensor may be deviated when assist control starts

even if there is a parked vehicle in the target parking spot. Have the
vehicle inspected at any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

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

GPF (Gasoline Particulate Filter) system

■

If “Exhaust filter full. See owner’s manual.” is shown on the multi-infor-
mation display

●

The message may be displayed while high load driving with particulate mat-
ter accumulating.

●

Hybrid system output (engine speed) is restricted when a certain amount of
particulate matter accumulates, however, it is possible to drive the vehicle
unless the malfunction indicator lamp comes on.

●

Particulate matter can accumulate more quickly if the vehicle is frequently
driven short trips or at low speeds, or if the hybrid system is regularly started
in an extremely cold environment. Excessive accumulation of particulate
matter can be prevented by periodically driving long distances continuously
with intermittent releasing of the accelerator pedal, such as when driving on
highways and freeways.

■

If the malfunction indicator lamp comes on or “Engine Maintenance
Required. Visit Your Dealer.” is shown on the multi-information display

The amount of accumulated particulate matter has exceeded a certain level.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer immediately.

The GPF system collects particulate matter in the exhaust gas
by using an exhaust gas filter.
The system will operate to regenerate the filter automatically,
depending on the vehicle conditions.

NOTICE
