Sonar’s obstacle recognition range
The recognition areas are shown in
the right figure.
However, if the obstacle is too close
to the sonar, the recognition fails.
Depending on the obstacles’ shape
and conditions, the recognition
range may become shorter, or the
recognition may fail.
⬛Operating conditions
⚫Front corner sensors:
⦁When the engine switch is “ON”
⦁ When the front corner sensors/reverse sensors switch is ON
⦁ When the shift lever is set in other than P, and the vehicle speed is approx.
10 km/h or less
⚫Reverse sensors:
⦁When the engine switch is “ON”
⦁ Vehicles with front corner sensors:
When the front corner sensors/reverse sensors switch is ON
⦁ When the shift lever is set in R, and the vehicle speed is approx. 10 km/h or
less
⚫When an obstacle is recognized with all the activation conditions satisfied
and the parking brake not being applied, the buzzer will sound.
⬛Sonar recognition capabilities
⚫The sonar recognition range is limited to the area around the sonar on the
front side of the vehicle and th e rear bumper of the vehicle.
⚫It takes some time from when the sonar recognizes an obstacle until the
front corner sensors or reverse sensors become activated. If the vehicle gets
too close to the obstacle before the buzzers sounds, the buzzer may not
sound even when the vehicle is traveling at a slow speed.
⚫While the audio or air conditioning system is turned on, the music or fan
noise makes the buzzer sound difficult to hear.

⬛When the high-pitch short beeps sound 3 times repeatedly and the front
corner sensor or reverse sensor ON indicator appears at 2 front locations
or 2 rear locations (or all 4 locations) simultaneously
⚫The front corner sensor or reverse se nsor functionality has been degraded.
When the front corner sensor or re verse sensor functionality temporarily
turns off, check if the sonar is not cove red with rain, snow, ice, or dirt. Remove
those attached to it, then wait for the f unctionality to be restored to normal.
⚫If the master warning light turns on at this time, it may indicate a malfunc-
tion of the system. Have the vehicle inspected at your Toyota dealer.
⚫Vehicles with TFT color multi-informati on display: Depending on the condi-
tions, the warning messages as “Son ar Sensor Function Stop” and “Sonar
Sensor Malfunction Visit Your Dealer” will be displayed.
⬛Front corner sensors and reverse sensors
In the following cases, the system ma y become activated even when there is
no obstacle within the operating range.
⚫When driving an area where the road slopes suddenly change
⚫When passing through plastic curtains or driving under flags
⚫When water splashes or drifting snow whirls up
⚫When passing an obstacle at close range
⚫When using an elevator for automobiles or using a mechanical parking lot
⚫When driving over a bump with an obstacle near the vehicle
⚫When there is an obstacle near the side of the vehicle
⚫When the road surface has large bumps, curbstones or protrusions, or when
the ground surface has tire tracks and holes
⚫When entering into a tight space
⚫During pouring rain or when water splashes over the vehicle
⚫Bad weather (heavy rain, snowstorm, fog, etc.)
⚫When the following is present near the vehicle: the sound of other vehicles’
horns, motorcycle engines, and air brakes of large vehicles, the devices emitting
ultrasonic waves, such as vehicle detect ors, or sonar systems of other vehicles
⚫When commercially available electrical components (such as an internally illu-
minated number plate, radio antenna) are installed near the sonar sensors
⚫When the vehicle body has been considerably tilted
⚫When the vehicle height has significantly changed by the load conditions, etc.
⚫When the direction of the sonar sensors is deviated by a collision or other
causes
⚫When the sonar sensors are covere d with rain, snow, ice or dirt

⬛Activation of ABS/VSC
ABS/VSC does not work at low speeds. The operation is the same as the nor-
mal brake.
⬛Activation sound and vibration of the ABS, brake assist, VSC, TRC, and hill-
start assist control
⚫A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine 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 oper-
ating. None of them indicates that a malfunction has occurred.
⦁ Vibrations may be felt through th e vehicle body and steering wheel
⦁ A motor sound may be heard even after the vehicle has come to a stop
⦁ The brake pedal may pulsate slightly after the ABS is activated
⦁ The brake pedal may move down slightly after the ABS is activated
⬛EPS motor operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard, but this does not indicate a malfunction.
⬛Automatic reactivation of VSC and TRC
After turning the TRC and VSC systems off, the systems will return to the ready
state in the following situations:
⚫When the engine switch is turned to “OFF”
⚫If only the TRC system is turned off, when vehicle speed increases
If both the TRC and VSC systems are tu rned off, automatic reactivation will
not occur when vehicle speed increases.
⬛Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel ma y feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle and
turn the engine off. It should re turn to normal within 10 minutes.

WARNING
⬛The ABS does not operate effectively when
⚫Do not overly rely on the ABS.
The limits of tire gripping performance have been exceeded (such as exces-
sively worn tires on a snow covered road).
⚫The vehicle hydroplanes while driving at high speed on wet or slick roads.
⬛Stopping distance when the ABS is operating may exceed that of normal
conditions
The ABS is not designed to shorten th e vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations:
⚫When driving on dirt, grav el or snow-covered roads
⚫When driving with tire chains
⚫When driving over bumps in the road
⚫When driving over roads with potholes or roads with uneven surfaces
⬛TRC/VSC may not operate effectively when
⚫Do not overly rely on the TRC/VSC.
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/VSC system is operating.
Drive the vehicle carefully in condit ions where stability and power may be
lost.
⚫The VSC and TRC may not function proper ly when tire chains are installed.
⬛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 an d dirt, gravel or snow-covered roads.
⚫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.
⚫The hill-start assist control may no t become activated depending on the
number of occupants or luggage weight in the vehicle, or if the driver did not
step on the brake pedal strong enough when stopping.
⬛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.
⬛When the ABS warning light or slip indicator is on
The emergency brake signal ( ➞P. 232) may not be activated.

When driving the vehicle
⚫Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
⚫During snowfall or cold weather, water adhering to the brake system
may freeze, and the brakes may become less effective. If brake perfor-
mance is poor, paying close attention to the surrounding safety, lightly
depress the brake pedal several times to confirm that the brakes work
properly until their effectiveness is restored.
⚫When driving on snowy roads, snow attached to the back of the wheel
wells freezes and may grad ually accumulate, making it difficult to steer.
Check that there is no abnormal build-up of snow from time to time. The
lights may become dark due to snow during driving, so make sure that
there is no abnormal build-up of snow from time to time.
When parking the vehicle
⚫The parking brake may freeze up, preventing it from being released. For
continuously variable transmission vehicles, set the shift lever to P. For
the manual transmission vehicles, set the shift lever to R on a downhill,
and set it to the gear 1 on an uphill to park. Do not apply the parking
brake at this time, and make sure to use wheel chocks.
Failure to do so may be dangerous because it may cause the vehicle to
move unexpectedly, possibly leading to an unforeseen accident.
⚫When you park the continuously variable transmission vehicle without
applying the parking brake, confirm that the shift lever will not move*
with the shift lever being placed in P.
*The shift lever will be locked if it is attempted to be shifted from P to any other
position without depressing the brake pe dal. If the shift lever can be shifted,
there may be a problem with the shift lo ck system. Have the vehicle inspected at
your Toyota dealer immediately.

Eco-friendly driving tips
For improved fuel economy and reduced CO2 emissions, pay atten-
tion to the following points:
◆Accelerator pedal/brake pedal operation
Drive your vehicle smoothly. Avoid abrupt acceleration and deceleration.
Gradual acceleration and deceleration will help reduce excessive fuel con-
sumption.
◆When braking
Observe conditions in front of and around the vehicle, and estimate your
stopping position. Release the accele rator pedal early and continue coast-
ing. Use the brake pedal to adjust your stopping position.
Make sure to operate the brake pedal gently.
◆Delays
Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fuel economy. Check traffic reports before leaving
and avoid delays as much as possible.
◆Highway driving
Control and maintain the vehicle at a constant speed. Before stopping at a
toll booth or similar, allow plenty of time to release the accelerator pedal
and gently apply the brakes.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive fuel consumption.
In summer: When the ambient temper ature is high, use the recirculated
air mode. Doing so will help to redu ce the burden on the air conditioning
system and reduce fuel consumption as well.
In winter: Turn the A/C switch on on ly when both heating and dehumidify-
ing are needed, and if only heating is needed, turn the A/C switch off.
Turning the A/C switch on when unnece ssary leads to excessive fuel con-
sumption.

2424-6. Driving tips
RAIZE_OM_General_BZ358E
◆Performing idling stops
⚫Avoid unnecessary idling. Stop the engine when parking the vehicle to
reduce excessive fuel consumption, even it is only for a short period of
time.
⚫Except in severe environment, such as when the outside temperature is
extremely low, warming up the engine before driving is unnecessary.
Rather than idling, it is more efficient to drive the vehicle gently to warm
up each part while avoiding increasing the engine revolutions unneces-
sarily and accelerating or decelerating suddenly.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆Regular maintenance
⚫Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fu el economy. Also, as snow tires can
cause large amounts of friction, thei r use on dry roads can lead to poor
fuel economy. Use tires that are appropriate for the season and road
conditions.
⚫Use oil and fluid of the recommended quality, which affect fuel con-
sumption and the life of the vehicle. Also, check oil and fluid periodically.
