761-2. Hybrid system
UK AURIS_HV_HB_EE (OM12M49E)
There is an air intake vent on the
side of the lower part of the rear
left seat for the purpose of cooling
the hybrid battery (traction bat-
tery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off sy stem activates, your vehicle will not restart.
To restart the hybrid system, cont act any authorized Toyota dealer or
repairer, or another duly qua lified and equipped professional.
A message is automatically displa yed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. ( P. 498)

■ Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 554)

The brake actuator uses brake fluid pressurized by the pump to power-assist
the brakes. If the brake actuator fails during driving, the brake system warn-
ing light comes on and the buzzer sounds intermittently. In this case, the
brakes may not work properly. If they do not work well, depress the brake
pedal firmly. If the brake system warning light comes on, immediately stop
your vehicle and contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
In the following conditions, you may hear a sound in the engine compartment.
This is not a malfunction.
● The driver’s door is opened with the hybrid system turned off.
● The brake pedal is depressed with the hybrid system turned off.
● After the hybrid system is turned on.
● The brake pedal is depressed repeatedly with the hybrid system turned on.
● After the hybrid system is turned off.
The brake pedal may be hard to depress or the brake pedal stroke may be
short before turning the hybrid system on. This is not a malfunction.
■ When braking the vehicle
When applying brakes, you may hear a sound coming from the motor gener-
ator.
However, this does not indicate any trouble.
