2023 TOYOTA RAV4 PLUG-IN HYBRID ABS

4165-5. Using the driving support systems
■VSC+ (Vehicle Stability Con-
trol+)
Provides cooperative control of the
ABS, TRC, VSC and EPS.
Helps to maintain directional stabil-
ity when swerving on slippery road
surfaces by controlling steering per-
formance.
■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying brake
pressure for individual wheels and
reducing driving torque when trailer
sway is detected.
■TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
■Active Cornering Assist (ACA)
Helps to prevent the vehicle from
drifting to the outer side by perform-
ing inner wheel brake control when
attempting to accelerate while turn-
ing
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel.
■E-Four (Electronic On-Demand
AWD system)
Automatically controls the drive
system such as to front-wheel drive
or AWD (all wheel drive) according
to various running conditions
including normal driving, during cor-
nering, on a uphill, when starting
off, during acceleration, on a slip-
pery roads due to snow or rain,
thus contributing to stable
operability and driving stability.
■Emergency brake signal
When the brakes are applied sud-
denly, the emergency flashers
automatically flash to alert the vehi-
cle behind.
■The Secondary Collision
Brake (if equipped)
When the SRS airbag sensor
detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the vehicle speed and
help reduce the possibility of further
damage due to a secondary colli-
sion.
■When the TRC/VSC/ABS/Trail
Mode/Trailer Sway Control systems
are operating
The slip indicator light will flash while the
TRC/VSC/ABS/Trail Mode/Trailer Sway
Control systems are operating.

■Sounds and vibrations caused by
the ABS, brake assist, VSC, Trailer
Sway Control, TRC and 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 mal-
function 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 indi-
cate that a malfunction has occurred.
●Operating sound heard from the
engine compartment when the brake
pedal is operated.
●Motor sound of the brake system
heard from the front part of the vehicle
when the driver’s door is opened.
●Operating sound heard from the
engine compartment when one or two
minutes passed after the stop of the
hybrid system.
■Active Cornering Assist operation
sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and vibra-
tions may be generated from the brake
system, but this is not a malfunction.
■Automatic reactivation of TRC,
Trailer Sway Control and VSC sys-
tems
After turning the TRC, Trailer Sway
Control and VSC systems off, the sys-
tems will be automatically re-enabled in
the following situations:
●When the power switch is turned off
●If only the TRC system is turned off,
the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are
turned off, automatic re-enabling will
not occur when vehicle speed
increases.
■Operating conditions of Active Cor-
nering Assist
The system operates when the following
occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate
while turning
●The system detects that the vehicle is
drifting to the outer side
●The brake pedal is released
■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 may feel
heavy as a result. Should this occur,
refrain from excessive steering input or
stop the vehicle and turn the hybrid sys-
tem off. The EPS system should return
to normal within 10 minutes.
■Operating conditions of emergency
brake signal
When the following conditions are met,
the emergency brake signal will operate:
●The emergency flashers are off.
●Actual vehicle speed is over 55 km/h
(35 mph).
●The system judges from the vehicle
deceleration that it is a sudden brak-
ing operation.
■Automatic system cancelation of
emergency brake signal
The emergency brake signal will be can-
celed in any of the following situations:
●The emergency flashers are turned
on.
●The system judges from the vehicle

WARNING
■TRC/VSC may not operate effec- tively when
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 condi-tions where stability and power may
be lost.
■Active Cornering Assist does not
operate effectively when
●Do not overly rely on Active Corner- ing Assist. Active Cornering Assist
may not operate effectively when accelerating down slopes or driving on slippery road surfaces.
●When Active Cornering Assist fre-quently operates, Active Cornering
Assist may temporarily stop operat- ing to ensure proper operation of the brakes, TRC and VSC.
■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 con- trol to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
■When the TRC/ABS/VSC/Trailer
Sway Control 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/Trailer Sway Control 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 driv-
ing force, do not turn the TRC/VSC/Trailer Sway Control sys-tems off unless necessary.
Trailer Sway Control is part of the VSC system and will not operate if VSC is turned off or experiences a
malfunction.
■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 pres-sure level.
The ABS, TRC, VSC and Trailer Sway Control systems will not func-tion correctly if different tires are
installed on the vehicle. Contact any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer for further information when replacing tires or wheels.
■Handling of tires and the suspen-sion
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may
cause a system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations. Depending on many fac-
tors such as the conditions of the vehicle, trailer, road surface and driv-ing environment, the Trailer Sway
Control system may not be effective. Refer to your trailer owner’s manual for information on how to tow your
trailer properly.
