■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■ When a message requesting the smart key system be inspected is dis-
played on the multi-information display
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.
■ If the electronic key battery is depleted
P. 435
■ Operation of the engine switch
●If the switch is not pressed shortly and firmly, the engine swi tch mode may
not change or the engine may not start.
● If attempting to restart the engine immediately after turning t he engine
switch off, the engine may not start in some cases. After turning the engine
switch off, wait a few seconds before restarting the engine.
■ If the smart key system has been d eactivated in a customized setting
P. 484
WARNING
■ When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious in jury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, res ulting in
death or serious injury.
■ Stopping the engine in an emergency
● If you want to stop the engine in an emergency while driving th e vehicle,
press and hold the engine switch for more than 2 seconds, or press it
briefly 3 times or more in succession. ( P. 445)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering
or braking control, but the power assist to these systems will be lost. This
will make it more difficult to steer and brake, so you should pull over and
stop the vehicle as soon as it is safe to do so.
● If the engine switch is operated while the vehicle is running, a warning
message will be shown on the multi-information display and a buzzer
sounds.
● When restarting the engine after it was turned off while drivin g, shift the
shift lever to N and press the engine switch.

1904-2. Driving procedures
WARNING
■When parking
Exhaust gases include harmful carbon monoxide (CO), which is co lorless
and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle a nd may
lead to an accident caused by light-headedness, or may lead to death or a
serious health hazard.
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
● Do not leave the vehicle with the engine running for a long time. If such a
situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
● Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.
NOTICE
■ To prevent battery discharge
● Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.
● If “ACCESSORY” or “IGNITION ON” is displayed on the multi-information
display, the engine switch is not off. Exit the vehicle after t urning the
engine switch off.
● Do not stop the engine when the shift lever is in a position ot her than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If t he vehi-
cle is left in ACCESSORY mode, battery discharge may occur.
■ When starting the engine
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your Toyota dealer immediately.
■ Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact
your Toyota dealer immediately.

1944-2. Driving procedures
■Automatic deactivation of shift range selection in the D positi on (vehi-
cles with paddle shift switches)
Shift range selection in the D position will be deactivated in the following situ-
ations:
● The “+” paddle shift switch is held down for a period of time
● When the vehicle comes to a stop
● If the accelerator pedal is depressed for more than a certain p eriod of time
● When the shift lever is shifted to a position other than D
■ S mode
●When the shift range is 7 or lower, holding the shift lever toward “+” sets the
shift range to 8.
● To prevent the engine from over-revving, upshifting may automat ically
occur.
● To protect the automatic transmission, a function is adopted that automati-
cally selects a higher shift range when the fluid temperature is high.
■ Downshift restriction warning buzzer (S mode or paddle shifting )
To help ensure safety and driving performance, downshifting ope ration may
sometimes be restricted. In some circumstances, downshifting ma y not be
possible even when the shift lever or paddle shift switches are operated. (A
buzzer will sound twice.)
■ When driving with dynamic radar cruise control with full-speed range
activated
Even when performing the following actions with the intent of e nabling engine
braking, engine braking will not activate because dynamic radar cruise con-
trol with full-speed range will not be canceled.
● While driving in D or S mode, downshifting to 7, 6, 5 or 4.
● When switching the driving mode to sport mode while driving in the D posi-
tion. (
P. 324)
■ Restraining sudden start (Drive-start Control)
P. 173
■ Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the engine switch is in the
IGNITION ON mode the brake pedal is depressed and the shift release but-
ton is pushed.

Turns the brake hold system on
The brake hold standby indicator
(green) comes on. While the sys-
tem is holding the brake, the brake
hold operated indicator (yellow)
comes on.
*1: Brake hold standby indicator
*2: Brake hold operated indicator
■Brake hold system operating conditions
The brake hold system cannot be turned on in the following cond itions:
● The driver’s door is not closed.
● The driver is not wearing the seat belt.
If any of the conditions above are detected when the brake hold system is
enabled, the system will turn off and the brake hold standby in dicator light will
go off. In addition, if any of the conditions are detected whil e the system is
holding the brake, a warning buzzer will sound and a message will be shown
on the multi-information display. The parking brake will then b e set automati-
cally.
■ Brake hold function
●If the brake pedal is left released for a period of about 3 min utes after the
system has started holding the brake, the parking brake will be set automat-
ically. In this case, a warning buzzer sounds and a message is shown on the
multi-information display.
● To turn the system off while the system is holding the brake, f irmly depress
the brake pedal and press the button again.
● The brake hold function may not hold the vehicle when the vehic le is on a
steep incline. In this situation, it may be necessary for the d river to apply the
brakes. A warning buzzer will sound and the multi-information d isplay will
inform the driver of this situation. If a warning message is sh own on the
multi-information display, read the message and follow the inst ructions.
Brake Hold
The brake hold system keeps the brake applied when the shift
lever is in D, S or N with the system on and the brake pedal has
been depressed to stop the vehicle. The system releases the
brake when the accelerator pedal is depressed with the shift
lever in D or S to allow smooth start off.

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh icle-
to-vehicle following distance, and operates to maintain a suita ble fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicl e
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+ RES” switch or depressing the accelerator pedal (start-off o peration) will
resume follow-up cruising. If the start-off operation is not pe rformed, sys-
tem control continues to keep your vehicle stopped.

After the vehicle ahead of you
starts off, press the “+ RES”
switch.
Your vehicle will also resume fol-
low-up cruising if the accelerator
pedal is depressed after the vehi-
cle ahead of you starts off.
Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is
depressed.
(When the vehicle has been
stopped by system control,
depressing the brake pedal does
not cancel the setting.)
Pressing the “+ RES” switch resumes the cruise control and returns
vehicle speed to the set speed.

■Dynamic radar cruise control wi th full-speed range can be set when
● The shift lever is in D.
● The desired set speed can be set when the vehicle speed is approximately
20 mph (30 km/h) or more.
(However, when the vehicle speed is set while driving at below approxi-
mately 20 mph [30 km/h], the set speed will be set to approximately 20 mph
[30 km/h].)
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicl e distance
control mode, the vehicle speed may decrease below the set spee d in order
to maintain the distance to the preceding vehicle.
■ When the vehicle stops while follow-up cruising
●Pressing the “+ RES” switch while the vehicle ahead stops will resume fol-
low-up cruising if the vehicle ahead starts off within approxim ately 3 sec-
onds after the switch is pressed.
● If the vehicle ahead starts off within 3 seconds after your vehicle stops, fol-
low-up cruising will be resumed.
■ Automatic cancelation of vehicle-to-vehicle distance control mo de
Vehicle-to-vehicle distance control mode is automatically cance led in the fol-
lowing situations.
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● The sensor cannot detect correctly because it is covered in some way.
● When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre -Collision System, Drive-Start Control)
● The parking brake is operated.
● The vehicle is stopped by system control on a steep incline.
● The following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes
If vehicle-to-vehicle distance control mode is automatically ca nceled for any
reasons other than the above, there may be a malfunction in the system.
Contact your Toyota dealer.

3104-5. Using the driving support systems
■The Intelligent Clearance Sonar function will operate when
The function will operate when the ICS OFF indicator is not illuminated or
flashing ( P. 306, 314) and all of the following conditions are met:
● Engine output restriction control
• The Intelligent Clearance Sonar system is enabled.
• The vehicle speed is 10 mph (15 km/h) or less.
• There is an object in the traveling direction of the vehicle a nd 6 to 13 ft. (2
to 4 m) away.
• The system determines that a stronger-than-normal brake operat ion is
necessary to avoid a collision.
● Brake control
• Engine output restriction control is operating.
• The system determines that an emergency brake operation is nec essary
to avoid a collision.
■ The Intelligent Clearance Sonar function will stop operating when
The function will stop operating if any of the following condit ions are met:
● Engine output restriction control
• The Intelligent Clearance Sonar system is disabled.
• The collision becomes avoidable with normal brake operation.
• The object is no longer 6 to 13 ft. (2 to 4 m) away in the traveling direction
of the vehicle.
● Brake control
• The Intelligent Clearance Sonar system is disabled.
• Approximately 2 seconds elapse after the vehicle is stopped by brake
control.
• The brake pedal is depressed after the vehicle is stopped by b rake con-
trol.
• The object is no longer 6 to 13 ft. (2 to 4 m) away in the traveling direction of the vehicle.
■ Detection range of the Intellig ent Clearance Sonar function
The detection range of the Intelligent Clearance Sonar function differs from
the detection range of the intuitive parking assist. ( P. 298)
Therefore, even if the intuitive parking assist detects an obje ct and provides a
warning, the Intelligent Clearance Sonar function may not start operating.
■ If the Intelligent Clearance Sonar function has operated
If the vehicle is stopped due to operation of the Intelligent C learance Sonar
function, the Intelligent Clearance Sonar system will be disabl ed and the ICS
OFF indicator will illuminate.
