■Engine speed
On hybrid vehicles, engine speed is precisely controlled in ord er to help
improve fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may dif fer 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.
■ Fuel gauge and driving range display
The fuel gauge and driving range display are linked. If the fue l gauge and
driving range display do not update after refueling a small amount, they can
be updated by performing the following procedure:
Stop the vehicle on a level surface.
Wait until the fuel in the fuel tank stabilizes.
Press the ODO/TRIP switch to change the odometer and trip meter display
to the odometer.
Turn the power switch off.
While pressing and holding the ODO/TRIP switch, turn the power switch to
ON mode.
Continue holding the ODO/TRIP switch for approximately 5 seconds.
Release the switch when the odometer begins blinking.
Updating will be complete when the odometer blinks for approximately 5
seconds and then returns to the normal display.
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. 537)

1984-1. 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 sunligh t 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 park ing 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 veh icle 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.

■Parking the vehicle
P. 192
■ 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 (automa tic
brake setting and releasing) is not available.
■ Automatic release function
The parking brake is automatica lly released when slowly depress the acceler-
ator pedal.
The parking brake will be released automatically under the foll owing 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 re lease the park-
ing brake.
■ If “Parking Brake Temporarily Un available” 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 displayed 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 malfuncti oning. 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 light and parking brake light
●Depending on the power switch mode, the parking brake indicator light and
parking brake light will turn on and stay on as described below:
ON mode: Comes on until the parking brake is released.
Not in ON mode: Stays on for approximately 15 seconds.
● When the power switch is turned off with the parking brake set, the parking
brake indicator light and parking brake light will stay on for about 15 sec-
onds. This does not indicate a malfunction.

2264-2. Driving procedures
■Parking brake engaged warning buzzer
A buzzer will sound if the vehicle is driven with the parking b rake engaged.
“Release Parking Brake” is displayed on the multi-information display.
■ Warning messages and buzzers

Driving
■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 wh en vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases
■ Secondary Collision Brake operating conditions
The system operates when the SRS airbag sensor detects a collis ion while
the vehicle is in motion.
However, the system does not operate in any of the following si tuations.
● The vehicle speed is below 6 mph (10 km/h)
● Components are damaged
■ 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 s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s 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.
