CAUTION
Emergency shut off system
Carefully check to see if there are exposed high voltage parts or cables.
Never touch the parts or cables. (P. 34)
Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.
Road accident cautions
If your vehicle is involved in an accident, observe the following precautions
to reduce the risk of injury.
Stop the vehicle in a safe place to prevent subsequent accidents. While
depressing the brake pedal, apply the parking brake and push the P posi-
tion switch to stop the hybrid system. Then, slowly release the brake
pedal.
Do not touch the high voltage parts, cables and connectors.
If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
If a fluid leak occurs, do not touch it as it may be strong alkaline electrolyte
from the hybrid battery (traction battery). If it comes into contact with your
skin or eyes, wash it off immediately with a large amount of water or if pos-
sible, boric acid solution. Seek immediate medical attention.
If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
If your vehicle needs to be towed, do so with the front wheels raised. If the
wheels with the electric motor (traction motor) are on the ground when
towing, the motor may continue to generate electricity. This may cause an
electricity leakage leading to a fire. (P. 423)
Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of
improperly, it is hazardous to the environment and there is a risk of severe
burns and electrical shock that may result in death or serious injury.

Eco-friendly driving
Eco-friendly driving can be achieved by driving with Hybrid System Indicator.
(P. 193)
Brake actuator
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 compart-
ment. 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.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
Pre-winter preparations
Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
Have a service technician inspect the level and specific grav-
ity of 12-volt battery electrolyte.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.
Before driving the vehicle
Perform the following according to the driving conditions.
Do not try to forcibly open a window, scrape an outside rear
view mirror surface or move a wiper or outside rear view mir-
ror that is frozen. Pour warm water over the frozen area to
melt the ice. Wipe away the water immediately to prevent it
from freezing.
To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
Remove any ice that has accumulated on the vehicle chassis.
Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.

Maintenance and care
UK_AURIS_HV_EE
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury observe the following precautions:
When working on the engine compartment
Keep hands, clothing, and tools away from the moving fan.
Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
When working near the electric cooling fan or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. (P. 379)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

NOTICE
If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
