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
VSC+ (Vehicle Stability Control +)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
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
Hill-start assist control (with Stop & Start system and Multi-
drive)
Helps to prevent the vehicle from rolling backwards when the brake
pedal is released to restart the engine
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

When the VSC/TRC systems are operating
The slip indicator light will flash
while the VSC/TRC systems are
operating.
Disabling the TRC system
If the vehicle gets stuck in mud, dirt or snow, the TRC system may
reduce power from the engine to the wheels. Pressing
to turn
the system off may make it easier for you to rock the vehicle in order
to free it.
Left-hand drive vehicles
To turn the TRC system off,
quickly press and release
.
The “TRC OFF” indicator light will
come on.
Press
again to turn the sys-
tem back on.

When driving
VERSO-S_EERight-hand drive vehicles
To turn the TRC system off,
quickly press and release
.
The “TRC OFF” indicator light will
come on.
Press
again to turn the sys-
tem back on.
Turning off both TRC and VSC systems
To turn the TRC and VSC systems off, press and hold
for more than 3
seconds while the vehicle is stopped.
The “TRC OFF” indicator light and the VSC OFF indicator light will come on.
Press again to turn the systems back on.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
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 reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
Vehicles without a smart entry & start system: When the engine switch is
turned to the “LOCK” position.
Vehicles with a smart entry & start system: When the “ENGINE START
STOP” 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.
Reactivation of the TRC system linked to vehicle speed
When the TRC system is turned off, it will turn on when vehicle speed
increases. However, when the TRC and VSC systems are turned off, the
systems will not turn on even 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 may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the engine
off. The EPS system should return to normal within 10 minutes.
If the slip indicator comes on...
It may indicate a malfunction in the driving assist systems. Contact any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional.

CAUTION
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 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, especially in the fol-
lowing 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 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.
Drive the vehicle carefully in conditions where stability and power may be
lost.
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 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 ensure vehicle stability and driving force,
do not turn the TRC/VSC systems off unless necessary.

CAUTION
Replacing tires
Observe the following precautions.
Failure to do so may cause the ABS, VSC and TRC systems not to function
correctly.
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity.
Do not use tires of noticeably different wear level.
Make sure that the tires are inflated to the recommended tire inflation
pressure level. (P. 531)
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 the 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.

Diesel particulate filter system (diesel engine only)
Replacing the engine oil
P. 380
CAUTION
Exhaust pipe
Do not touch the exhaust pipe during regeneration, as the exhaust pipe and
exhaust gases will become particularly hot. Also, make sure that there are
no people or flammable materials near the exhaust pipe while the vehicle is
stopped.
Failure to do so may cause injury by burning or a fire.
When the deposit collected by the filter reaches a predetermined
amount, it is automatically cleaned.
Cleaning the DPF catalytic converter
Cleaning the DPF catalytic converter is performed as necessary
in accordance with driving conditions.
Equipment characteristics
The DPF system has the following characteristics:
Idle speed increases during cleaning
The smell of the exhaust gas changes
When starting the engine, white-colored steam (water vapor)
may be expelled during cleaning
Acceleration performance may degrade during cleaning

NOTICE
To prevent the DPF system from failing
Do not use fuel other than the specified type
Do not use engine oil other than the recommended type
Do not modify the exhaust pipe
