Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
TRC (Traction Control)
Helps to maintain drive power and prevent the front wheels from spin-
ning when starting the vehicle or accelerating on slippery roads.
Hill-start assist control
P. 232
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

When driving
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.

Hill-start assist control
Hill-start assist control operating conditions
The system operates in the following situations:
• The shift position is other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
Hill-start assist control
While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicle to roll backward) and then firmly
depress it again. If the system still does not operate, check that the oper-
ating conditions explained above have been met.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

CAUTION
When raising your vehicle
Make sure to observe the following to reduce the possibility of death or seri-
ous injury.
When using a floor jack, follow the instructions of the manual provided with
the jack.
Do not use the jack that was supplied with your vehicle.
Do not put any part of your body or get underneath the vehicle supported
only by the floor jack.
Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
Do not start the hybrid system while the vehicle is supported by the floor
jack.
Stop the vehicle on level, firm ground, firmly set the parking brake and
push the P position switch.
Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
Do not raise the vehicle while someone is in the vehicle.
When raising the vehicle, do not place any objects on top of or underneath
the floor jack.
Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

When trouble arises
UK_AURIS_HV_EETo change “POWER” switch modes: Within 5 seconds of the
buzzer sounding, release the brake pedal and press the
“POWER” switch. Modes can be changed each time the
switch is pressed. (P. 176)
To start the hybrid system: Press the “POWER” switch within
5 seconds after the buzzer sounds, keeping the brake pedal
depressed.
In the event that the “POWER” switch still cannot be operated, con-
tact any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional.
Stopping the hybrid system
Push the P position switch and press the “POWER” switch as you normally
do when stopping the hybrid system.
Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the
electronic key battery be replaced immediately when the battery depletes.
(P. 397)
Alarm (if equipped)
Using the mechanical key to lock the doors will not set the alarm system. If a
door is unlocked using the mechanical key when the alarm system is set, the
alarm may be triggered. (P. 115)

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.
