“IPA cancelled, take
over.”
The steering wheel
could not be turned suf-
ficiently due to reasons
such as low tire pres-
sure, tire wear, the
influence of road condi-
tions, being on a slope,
etc., therefore the vehi-
cle could not be parked
in the desired space.
• Check tires for wear
and pressure.
• If this message is dis-
played when the
vehicle is parked in
other spaces, have
the vehicle inspected
by any authorized
Toyota dealer or
repairer, or another
duly qualified and
equipped profes-
sional.

heated.

The vehicle speed
exceeded 50 km/h (31

of a parking space.
Reduce vehicle speed
to 30 km/h (18 mph) or
less and turn the Sim-
ple-IPA switch on.
The vehicle speed
exceeded 6 km/h (3
mph) during automatic
steering.
Park the vehicle manu-
ally or detect another

WARNING
■Conditions in which the use of Simple-IPA is prohibited
Do not use Simple-IPA under the following conditions.
Doing so may cause improper operation and lead to an unexpected acci-
dent.
● On sharp bends or slopes.
● On slippery or icy roads, or in snow.
● On uneven road surfaces such as gravel.
● During bad weather such as heavy rain, fog, snow, or a sandstorm.
● When the tires are extremely worn or tire pressure is low.
● When the vehicle has improper wheel alignment due to tires having
received a strong impact such as bumping against a curb.
● When the compact spare tire (if equipped) or snow chains are installed.
● When the tires slid while attempting to park.
● When fallen leaves or snow is in a parking space.
● Models that can tow a trailer: When items such as a towing bracket, trailer,
bicycle carrier, etc. are installed on the rear of the vehicle.
● When a vehicle of which the front/rear end is above the detection area,
such as a truck, bus or vehicle with a towing bracket, trailer, bicycle carrier,
etc., is parked at the front or rear of the parking space.
● If the front bumper has been damaged.
● If the sensor is covered by the front bumper cover, etc.
● If a vehicle or obstacle is not in a suitable position at the front or rear of the
parking space.
■ Automatic steering precautions
As the steering wheel moves automatically in the parking assist function, be
aware of the following point.
● Keep clothing such as neckties, scarves and long sleeves away from the
steering wheel, as they may become entangled. Also, keep children away
from the steering wheel.
● If you have long fingernails, be careful not to injure yourself when the
steering wheel moves.

WARNING
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
3124-7. Driving tips
UK AURIS_HV_HB_EE (OM12M49E)
◆When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad f uel economy. Check traffic reports
before leaving and avoid delays as much as possible. When driving
in a traffic jam, gently release th e brake pedal to allow the vehicle to
move forward slightly while avoi ding overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.
◆Highway driving
Control and maintain the vehicle at a constant speed. Before stop-
ping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the br akes. A greater amount of elec-
trical energy can be regenerated when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system and reduce fuel consumption as well.
In winter: Because the gasoline engi ne will not automatically cut out
until it and the interior of the vehicle are warm, it will consume fuel.
Also, fuel consumption can be impr oved by avoiding overuse of the
heater.
◆Checking tire inflation pressure
Make sure to check the tire infl ation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Also, as snow tires can cause larg e amounts of friction, their use on
dry roads can lead to poor fuel economy. Use tires that are appro-
priate for the season.

● Install tire chains on front tires as tightly as possible. Retighten chains after
driving 0.5 1.0 km (1/4 1/2 mile).
● Install tire chains following the instructions provided with the tire chains.
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
■ Repairing or replacing snow tires (vehicles with a tire pressure warn-
ing system)
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains (vehicles with a tire pressure warning system)
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
