■Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even
when vehicle operation and driving conditions are the same.
■ Outside temperature display
In the following situations, the correct outside temperature may not be \
dis-
played, or the display may take longer than normal to change:
●When stopped, or driving at low speeds (less than 16 mph [25 km/h])
● When the outside temperature has changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
● When “ − −” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to your Toyota dealer.
NOTICE
■ To prevent damage to the engine and its components
The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( →P. 519)

1964-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
● Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift lever to P, stop the hybrid
system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-
nated.
If the vehicle is parked with the shift lever in P but the parking brake is not
set, the vehicle may start to move, possibly leading to an accident.
● Do not touch the exhaust pipes while the “READY” indicator is illuminated
or immediately after turning the hybrid system off.
Doing so may cause burns.
■ When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle is parked in
a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the electronically controlled brake system does not operate, do not fol-
low other vehicles closely and avoid hills or sharp turns that require brak-
ing.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
● The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In this case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.

■When the steering lock cannot be released
■ Steering lock motor o verheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system. 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 “READY” indicator does not come on
In the event that the “READY” indicator does not come on even after perform-
ing the proper procedures for starting the vehicle, contact your Toyota dealer
immediately.

■ Operation of the power switch
●If the switch is not pressed shortly and firmly, the power switch mode may
not change or the hybrid system may not start.
● If attempting to restart the hybrid system immediately after turning the power
switch off, the hybrid system may not start in some cases. After turning the
power switch off, wait a few seconds before restarting the hybrid system.
■ If the smart key system has been deactivated in a customized setting
→P. 509 A message informing the driver that the
steering wheel is locked will be displayed
on the multi-information display.
Check that the shift lever is set in P. Press
the power switch while turning the steer-
ing wheel left and right.

2224-2. Driving procedures
■Parking the vehicle
→P. 190
■ Parking brake operation
●When the power switch is not in ON mode, the parking brake cannot be
released using the parking brake switch.
● When the power switch is not in ON mode, automatic mode (automatic
brake setting and releasing) is not available.
■ Automatic release function
The parking brake is automatically released when slowly depress the acceler-
ator pedal.
The parking brake will be released automatically under the following condi-
tions:
●The driver’s door is closed.
● The driver’s seatbelt is fastened.
● Shift the shift lever is in a forward or reverse position.
● The malfunction indicator lamp or brake system warning light is not illumi-
nated.
If the automatic release function does not operate, manually release the park-
ing brake.
■ If “Parking Brake Temporarily Unavailable” is displayed on the multi-
information display
If the parking brake is operated repeatedly over a short period of time, the
system may restrict operation to prevent overheating. If this happens, refrain
from operating the parking brake. Normal operation will return after about 1
minute.
■ If “Parking Brake Unavailable” is disp layed on the multi-information dis-
play
Operate the parking brake switch. If the message does not disappear after
operating the switch several times, the system may be malfunctioning. Have
the vehicle inspected by your Toyota dealer immediately.
■ Parking brake operation sound
When the parking brake operates, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Parking brake indicator li ght and parking brake light

■Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the power switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases
■ Secondary Collision Brake operating conditions
The vehicle speed is approximately 6 m ph (10 km/h) or more and the airbag
sensor detects a collision. (The Secondary Collision Brake will not operate
when the vehicle speed is below approximately 6 mph [10km/h].)
■ Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situ-
ations:
●The vehicle speed drops below approximately 6 mph (10 km/h)
● A certain amount of time elapses during operation
● The accelerator pedal is depressed a large amount
■ 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 hybrid system
off. The EPS system should return to normal within 10 minutes.
