When braking the vehicle (hybrid model)
When applying brakes, you may hear a sound coming from the motor gener-
ator.
However, this does not indicate any trouble.
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When starting the vehicle (vehicles without a manual transmission)
Vehicles with a Multidrive: Always keep your foot on the brake pedal while
stopped with the engine running. This prevents the vehicle from creeping.
Vehicles with a multi-mode manual transmission: Always keep your foot on
the brake pedal while stopped with the engine running. This prevents the
vehicle from moving unexpectedly.
Vehicles with a hybrid transmission: Always keep your foot on the brake
pedal while stopped with the hybrid system operating. This prevents the
vehicle from creeping.
When driving the vehicle
Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
Hybrid model: The driver should pay attention to pedestrians when the
vehicle is powered only by the electric motor (traction motor). Because
there is no hybrid system sounds, the pedestrians may misjudge the vehi-
cle’s movement.
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When driving the vehicle
Except hybrid model: During normal driving, do not turn off the engine.
Turning the engine off while driving will not cause loss of steering or brak-
ing 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. 573
Hybrid model: 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. 573
Use engine braking (downshift [except hybrid model] or shift position B
[hybrid model]) to maintain a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 276, 281, 286, 289)
Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.

Driving
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When driving on slippery road surfaces
Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid, resulting in an accident.
After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.
When shifting the shift lever
Vehicles without a manual transmission: Do not let the vehicle roll back-
ward while the shift lever is in a driving position, or roll forward while the
shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering
performance, resulting in an accident or damage to the vehicle.
Hybrid model: Do not let the vehicle roll backwards while a forward driving
position is selected, or roll forward while R is selected.
Doing so result in an accident or damage to the vehicle.
Vehicles with a Multidrive: Do not shift the shift lever to P while the vehicle
is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Hybrid model: Do not shift the shift position to P while the vehicle is mov-
ing.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Except hybrid model: Do not shift the shift lever to R while the vehicle is
moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Hybrid model: Do not shift the shift position to R while the vehicle is mov-
ing forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.

CAUTION
Except hybrid model: Do not shift the shift lever to D (Multidrive), E, M
(multi-mode manual transmission) or 1 (manual transmission) while the
vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Hybrid model: Do not shift the shift position to D while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Except hybrid model: Moving the shift lever to N while the vehicle is mov-
ing will disengage the engine from the transmission. Engine braking is not
available when N is selected.
Hybrid model: 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.
Vehicles without a manual transmission (except hybrid model): Be careful
not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to a gear other than P (Multidrive) or N may lead to unexpected
rapid acceleration of the vehicle that may cause an accident and result in
death or serious injury.
Hybrid model: Be careful not to change the shift position with the acceler-
ator pedal depressed.
Changing the shift position to any positions other than P or N may lead to
unexpected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
After the shift lever is operated, make sure to check the current shift posi-
tion using the shift position indicator. (P. 289)

CAUTION
If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional as
soon as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
When the vehicle is stopped
Except hybrid model: Do not race the engine.
If the vehicle is in any gear other than P (Multidrive) or N, the vehicle may
accelerate suddenly and unexpectedly, causing an accident.
Hybrid model: Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any positions other than P or N, the vehicle may accel-
erate suddenly and unexpectedly, causing an accident.
Except hybrid model (vehicles without a manual transmission): In order to
prevent accidents due to the vehicle rolling away, always keep depressing
the brake pedal while the engine is running, and apply the parking brake
as necessary.
Hybrid model: In order to prevent accidents due to the vehicle rolling
away, always keep depressing the brake pedal while the “READY” indica-
tor is on. Apply the parking brake as necessary.
If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

UK_AURIS/AURIS_HV_EE (OM12E33E)
CAUTION
When the vehicle is parked
Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
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 sunlight may cause
the glass to act as a lens, causing a fire.
Vehicles with a Multidrive: Always apply the parking brake, shift the shift
lever to P (Multidrive), stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
Vehicles with a multi-mode manual transmission: Always apply the park-
ing brake, shift the shift lever to E, M or R, stop the engine and lock the
vehicle.
Do not leave the vehicle unattended while the engine is running.
Vehicles with a hybrid transmission: Always apply the parking brake, shift
the shift position to P, stop the hybrid system and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system is operating.
Except hybrid model: Do not touch the exhaust pipes while the engine is
running or immediately after turning the engine off.
Doing so may cause burns.
Hybrid model: Do not touch the exhaust pipes while the hybrid system is
operating or immediately after turning the hybrid system off.

Driving
CAUTION
Vehicles with a multi-mode manual transmission: Do not turn off the
engine until 1st or reverse is engaged properly and completely. Confirm
that the gear is engaged by viewing the gear position indicator.
Parking the vehicle without a gear engaged may cause the vehicle to
move result in an accident.
When taking a nap in the vehicle
Except hybrid model: Always turn the engine off. Otherwise, if you acciden-
tally move the shift lever or depress the accelerator pedal, this could cause
an accident or fire due to engine overheating. Additionally, if the vehicle is
parked in a poorly ventilated area, exhaust gases may collect and enter the
vehicle, leading to death or a serious health hazard.
Hybrid model: Always turn the hybrid system off. Otherwise, if you acciden-
tally move the shift lever or depress the accelerator pedal, this could cause
an accident or fire due to hybrid system overheating. Additionally, if the
vehicle 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 brake actuator (hybrid model) or brake booster (except hybrid model)
does not operate, do not follow other vehicles closely and avoid hills or
sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Except hybrid model: Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.

driving, as this may restrain driving torque.
Do not shift gears unless the clutch pedal is fully depressed. After shifting,
do not release the clutch pedal abruptly. Doing so may damage the clutch,
transmission and gears.
Observe the following to prevent the clutch from being damaged.
• Do not rest your foot on the clutch pedal while driving.
Doing so may cause clutch trouble.
• Do not use any gear other than the 1st gear when starting off and mov-
ing forward.
Doing so may damage the clutch.
• Do not use the clutch to hold the vehicle when stopping on an uphill
grade.
Doing so may damage the clutch.
Do not shift the shift lever to R when the vehicle is still moving. Doing so
may damage the clutch, transmission and gears.
When parking the vehicle (vehicles with a Multidrive)
Always shift the shift lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is
accidentally depressed.
Avoiding damage to vehicle parts
Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
Diesel model: Make sure to idle the engine immediately after high-speed
driving or hill climbing. Stop the engine only after the turbocharger has
cooled down.
Failure to do so may cause damage to the turbocharger.

wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds or vibrations.
The vehicle will lean abnormally.
Information on what to do in case of a flat tire (P. 626, 638)
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
Engine stalling
Short in electrical components
Engine damage caused by water immersion

saxle fluid, etc.
Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
Hybrid model: If the P position control system is damaged by flooding, it
may not be possible to shift the shift position to P, or from P to other posi-
tions. When the shift position cannot be changed from P to any other posi-
tion, the front wheels will lock, and you will be unable to tow the vehicle with
the front wheels on the ground, as the front wheels may be locked. In this
case, transport the vehicle with both front wheels or all four wheels lifted.
