1-6. Theft deterrent system
Engine immobilizer system
The vehicle's keys have built-in transponder chips that prevent the
engine from starting if the key has not been previously registered in
the vehicle's on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
This system is designed to help prevent vehicle theft but does not
guarantee absolute security against all vehicle thefts.
Vehicles without a smart
entry & start system
The indicator light flashes after
the key has been removed
from the engine switch to indi-
cate that the system is operat-
ing.
The indicator light stops flash-
ing after the registered key
has been inserted into the
engine switch to indicate that
the system has been can-
celed.

WARNING
■
If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the engine, this could mean that these systems are
not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by any authorized Toyota dealer
or repairer, or another duly qualifi ed and equipped professional immediately
if this occurs.
*4: Vehicles with a monochrome multi-information display only: This light turns on when the engine switch is turned to the “ON” position
to indicate that a system check is being performed. It will turn off
after the engine is started, or after a few seconds. There may be a
malfunction in a system if the light does not come on or turn off.
Have the vehicle inspected by your Toyota dealer for details.

Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
■TRC (Traction Control)
Helps to maintain drive power and pr event the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads.
The TRC system is also equipped with the brake LSD function.
■ Hill-start assist control
→
P. 253
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
■Emergency brake signal
When the brakes are applied suddenly, the emergency flashers auto-
matically flash quickly to alert the vehicle behind.

■ Sounds and vibrations caused by the ABS, brake assist, TRC and VSC
systems
●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
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 after the vehicle comes 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 operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.

■
Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
●The emergency flashers are turned on.
● The brake pedal is released.
● The system judges from the vehicle deceleration that is not a sudden
braking operation.
■ Customization that can be conf igured at your Toyota dealer
Settings (e.g. emergency brake signal) can be changed.
(Customizable features →P. 487)
WARNING
■The ABS does not operate effectively when
●Tires with inadequate gripping ability are used (such as excessively 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 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 in the following situ-
ations:
●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 may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.

WARNING
■
When the VSC and/or brake LSD function 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 TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Hill-star t assist control
Hill-start assist control helps to maintain braking force to assist
starting off forward while facing uphill or starting off backward while
facing downhill. As hill-start assist control is initially disabled,
enable the system to make it oper able. The enabled/disabled setting
will be maintained the next time the engine is started.
The hill-start assist control ON
indicator will be illuminated
when system is enabled and
flash while the system is oper-
ating.
■ Enabling hill-start assist control
Park your vehicle in a flat, safe location.
Make sure that the parking brake is securely engaged.
Stop the engine by turning the engine switch to the “LOCK”
position (vehicles without a smart entry & start system) or
turning the “ENGINE START STOP” switch off (vehicles
with a smart entry & start system).
Start the engine and check that the ABS warning light and
slip indicator are off.
Press and hold for
approximately 30 seconds.
Check that both the VSC off
indicator and “TRC OFF” indi-
cator illuminate and then turn
off.
