NOTICE
If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional, as soon as
possible.
The rotor damage can result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or that of the brake discs are exceeded.
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually press the brake pedal to slow down the vehicle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds.
The vehicle will behave abnormally.
If a tire goes flat, confirm the extent of the damage to the tire.
If the tire is reparable, complete the emergency repair procedure.
(P. 405)
If the tire is irreparable, please contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.

When driving
iQ_WE_74014E
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. 108)
Key reminder function
A buzzer sounds if the driver’s door is opened while the engine switch is in
the ACC or LOCK 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 depress the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Caution while driving
Do not turn the engine switch to the LOCK position.
If in an emergency, you must turn the engine off while the vehicle is moving,
turn the engine switch only to the ACC position.
Shift the shift lever to P (Multid-
rive) or N (manual transmission).
(P. 185189)
Push in the key and turn to the
LOCK position.
When starting the engine, the engine
switch may seem stuck in the LOCK posi-
tion. To free it, turn the key while turning
the steering wheel slightly in either direc-
tion.

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.
Steering lock release
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.
If the engine does not start
P. 423
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.
Make sure that the steering wheel lock is
released.
To release the steering wheel lock, gently
turn the wheel left or right while pressing
the “ENGINE START STOP” switch.
If the steering wheel lock does not
release, the “ENGINE START STOP”
switch indicator will flash green.

2-4. Using other driving systems
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)
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.

226 2-4. Using other driving systems
iQ_WE_74014E
Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
Vehicles without smart entry & start system
When the engine 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 reactivation
will not occur when vehicle speed increases.
Vehicles with 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 reactivation
will not occur when vehicle speed increases.
Sounds and vibrations caused by the ABS, VSC, TRC and brake assist
systems
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 is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.

When driving

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.
CAUTION
The following situations may lead to an accident resulting in serious injury or
even death.
The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded.
The vehicle hydroplanes while driving at high speed on the wet or slick
road.
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 roads with uneven roads
When TRC may not operate effectively
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.
When the VSC is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator flashes.
