When driving
UK_AURIS_HV_EE
CAUTION
If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional, immediately.
Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift position to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Moving the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hybrid system
disengaged.
During normal driving, do not turn off the hybrid system. Turning the hybrid
system 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.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 486
To help maintain a safe speed when driving down a steep hill, apply
engine braking (use the B position for engine braking).
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 181)
When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.
Do not use the accelerator pedal or depress the accelerator and brake
pedals together to hold the vehicle on a hill.

By keeping the indicator needle within Eco area, more Eco-friendly driv-
ing can be achieved.
Charge area indicates regeneration* status. Regenerated energy will be
used to charge the battery.
Eco Driving Indicator Light can be enabled or disabled. (P. 201)
*: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.
NOTICE
To prevent damage to the hybrid system and its components
The hybrid system may be overheating if the top segments of the engine
coolant temperature gauge are flashing. In this case, immediately stop the
vehicle in a safe place, and check the hybrid system after it has cooled com-
pletely. (P. 479)

234 2-4. Using other driving systems
UK_AURIS_HV_EE
When the VSC/TRC systems are operating
If the vehicle is in danger of slip-
ping or the front wheels spin, the
indicator flashes to indicate that
the VSC/TRC systems have
been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed repeatedly, or 1 - 2 minutes after the hybrid system is
stopped. This sound does not indicate 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 indicate 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 operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
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 hybrid system off.
The system should return to normal within 10 minutes.

If your vehicle overheats
Correction procedures
If the top segments of the engine coolant temperature gauge
are flashing
Stop the vehicle in a safe place and turn off the air condition-
ing system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the hybrid system. Carefully lift the hood after the
steam subsides and then restart the hybrid system.
If you do not see steam:
Leave the hybrid system operating and carefully lift the
hood.
The following may indicate that your vehicle is overheating:
The top segments of the engine coolant temperature gauge are
flashing:
The engine may be overheating.
“HYBRID SYSTEM OVERHEAT” is shown on the multi-informa-
tion display:
The power control unit may be overheating.
Follow the correction procedure as described below.
