If the engine does not start
The engine immobilizer system may not have been deactivated. (P. 112)
Steering lock
When the “ENGINE START STOP” switch is turned off and then a door is
opened and closed, the steering lock function locks the steering wheel in its
current position. The steering lock is disabled when the “ENGINE START
STOP” switch is operated again.
When the steering lock cannot be released
Steering lock motor overheat prevention
If the engine is started and stopped repeatedly in a short time, operation of
the steering lock motor is restricted to prevent overheating. If this occurs,
wait momentarily without operating the “ENGINE START STOP” switch. The
system will return to its normal condition in approximately 10 seconds.
When the “ENGINE START STOP” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional, immediately.
Auto power off function
Vehicles with a Multidrive or an automatic transmission
If the vehicle is left in the ACCESSORY mode for more than an hour with
the shift lever in “P”, the “ENGINE START STOP” switch will automatically
turn OFF.
Vehicles with a manual transmission
If the vehicle is left in the ACCESSORY mode for more than an hour, the
“ENGINE START STOP” switch will automatically turn OFF.
The green indicator light on the “ENGINE
START STOP” switch will flash and a
message will be shown on the multi-infor-
mation display. To free it, press the
“ENGINE START STOP” switch while
turning the steering wheel slightly in
either direction.

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 +) (if equipped)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
TRC (Traction Control) (if equipped)
Maintains drive power and prevents the front wheels from spinning
when starting the vehicle or accelerating on slippery roads.
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

VERSO_WE_OM64524E
When the TRC and VSC+ are operating
If the vehicle is in danger of slip-
ping or if the front wheels spin,
the slip indicator light flashes to
indicate that the TRC/VSC+ sys-
tems are operating.
A buzzer (intermittent) sounds to
indicate that VSC+ is operating.
To disable TRC and/or VSC+
If the vehicle gets stuck in fresh snow or mud, the TRC and VSC+
systems may reduce power from the engine to the wheels. You may
need to turn the system off to enable you to rock the vehicle in order
to free it.
Turning off TRC
Quickly push and release the
button to turn off TRC.
The slip indicator light should
come on.
Push the button again to turn the
system back on.

Sounds and vibrations caused by the ABS, brake assist, TRC and
VSC+
A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate 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 operates, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
Reduced effectiveness of EPS
The effectiveness of EPS 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 sys-
tem should return to normal after about 10 minutes.

CAUTION
Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the speci-
fied tire pressure level.
The ABS and VSC+ systems will not function correctly if different tires are fit-
ted 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 the system to malfunction.

When driving
VERSO_WE_OM64524E
Before driving the vehicle
Perform the following according to the driving conditions:
Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
Remove any ice that has accumulated on the vehicle chassis.
Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.
When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
When parking the vehicle
Park the vehicle and move the shift lever to “P” (Multidrive or
automatic transmission) or to “1” or “R” (manual transmission)
without setting the parking brake. The parking brake may freeze
up, preventing it from being released. If necessary, block the
wheels to prevent inadvertent sliding or creeping.

CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the size specified for your vehicle.
Maintain the recommended level of tire inflation pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Snow tires should be installed on all wheels.
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden turns and braking, as use of chains may adversely affect
vehicle handling.
Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
