■Turning the key from “ACC” to “LOCK”
■ Steering lock release
■ If the engine does not start
The engine immobilizer system may not have been deactivated. ( P. 92)
■ Key reminder function
A buzzer sounds if the driver’s door is opened, while the engine switch is in
the “LOCK” or “ACC” position to remind you to remove the key.
CAUTION
■When starting the engine
Always start the engine while sitting in the driver's seat. Do not press the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution when driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the engine off while the vehicle is moving, turn the
key only to the “ACC” position.
Shift the shift lever to P.
(P. 150)
Push in the key and turn to the
“LOCK” position.STEP 1
STEP 2
When starting the engine, the engine
switch may seem stuck in the “LOCK”
position. To free it, turn the key while turn-
ing the steering wheel slightly in either
direction.

■After adjusting the steering wheel
Make sure that the steering wheel is securely locked.
The horn may not sound if the steering wheel is not securely locked.
(P. 76)
To sound the horn, press on or
close to the mark.

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily 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.
■TRAC (Traction Control)
Maintains drive power and prevents the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■AUTO LSD function (2WD models)
The AUTO LSD function is activated when the system is in TRAC off
mode. It operates when one of the drive wheels is spinning, such as
when the wheel is spinning freely on ice or mud. The system applies
the brakes to the spinning wheel and transfers some of the torque to
the other wheel to secure drive power.
■Active Torque Control 4W D system (4WD models)
Automatically switches from front-wheel drive to four-wheel drive
(4WD) according to the driving conditions, helping to ensure reliable
handling and stability. Examples of conditions where the system will
switch to 4WD are when cornering, going uphill, starting off or acceler-
ating, and when the road surface is slippery due to snow, rain, etc.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

2-4. Using other
driving systems
2
When driving
When the VSC/TRAC are operating
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator light
flashes to indicate that the VSC/
TRAC systems are operating.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
■Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surface by controlling steering performance.
■Hill-start assist control (if equipped)
(P. 191)
■ Downhill assist cont rol system (if equipped)
(P. 193)

188 2-4. Using other driving systems
■Automatic reactivation of TRAC and VSC
Vehicles without smart key system
Turning the engine switch OFF after turning off the TRAC and VSC systems
will automatically re-enable them.
Vehicles with smart key system
Turning the “ENGINE START STOP” switch OFF after turning off the TRAC
and VSC systems will automatically re-enable them.
■ Automatic TRAC reactivation
2WD models
If only the TRAC system is turned off, the TRAC system will be reactivated
while vehicle speed is increased. 4WD models
If only the TRAC system is turned off, the TRAC system will turn on when
vehicle speed increases.
■ Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on
even when vehicle speed increases.
■ Sounds and vibrations caused by the ABS, TRAC 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 when the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ When the AUTO LSD function operates continuously
The brake actuator may overheat. In that case, the system will stop the
AUTO LSD function, a buzzer will sound and the slip indicator will stay on
steady. Refrain from using the AUTO LSD function until the slip indicator
goes off. (There is no problem with continuing driving normally.)

2-4. Using other
driving systems
2
When driving
■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 within 10 minutes.
■ If the slip indicator comes on
It may indicate a malfunction in the VSC, TRAC and AUTO LSD function.
Contact your Toyota dealer.
CAUTION
■The ABS does not opera te 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 road.
■ Stopping distance when the ABS is ope rating on the wet or slick roads
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 roads
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
