NOTICE
Hybrid battery air vents
Do not put foreign objects over or in front of the air vents. The hybrid bat-
tery (traction battery) may overheat and be damaged.
Clean the air vents regularly to prevent the hybrid battery (traction battery)
from overheating.
Do not wet or allow foreign substances to enter the air vents as this may
cause a short circuit and damage the hybrid battery (traction battery).
Do not put in foreign objects into the air vents. The cooling blower may be
damaged.
Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.

CAUTION
The display at low temperatures
Allow the interior of the vehicle to warm up before using the display. At
extremely low temperatures, the display monitor may respond slowly, and
display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in death or injury.
Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area
such as a garage, exhaust gases including harmful carbon monoxide (CO)
may collect and enter the vehicle. This may lead to death or a serious
health hazard.
NOTICE
To prevent damage to the engine and its components
Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
The engine may be overheating if the engine coolant temperature gauge
are in the red zone (except hybrid model), or the engine coolant tempera-
ture warning message is shown (hybrid model). In these cases, immedi-
ately stop the vehicle in a safe place, and check the engine (except hybrid
model) or hybrid system (hybrid model) after it has cooled completely.

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
Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong
crosswinds will affect handling. The vehicle may also be rocked by
passing buses or large trucks. Frequently check behind when mov-
ing alongside such vehicles. As soon as such vehicle movement
occurs, immediately start to decelerate smoothly by slowly applying
the brakes. Always steer the vehicle straight ahead while braking.
Passing other vehicles
Consider the total combined length of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before exe-
cuting lane changes.
Transmission information
Multidrive:
To maintain engine braking efficiency, when using engine braking,
do not use the transmission in D.
Multi-mode manual transmission:
Select an appropriate gear in M position to maintain the effective-
ness of engine braking and to maintain charging system perfor-
mance.
Manual transmission:
Refrain from driving in 6th gear to maintain the effectiveness of
engine braking and to maintain charging system performance.
If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If the
engine coolant temperature gauge indicates that the engine is over-
heating, turn the air conditioning off immediately, leave the road and
stop the vehicle in a safe place. (P. 685)

2524-1. Before driving
UK_AURIS/AURIS_HV_EE (OM12E33E)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever to P
(Multidrive), E, M or R (multi-mode manual transmission) and 1 or R
(manual transmission).
CAUTION
Follow all the instructions described in this section. Failure to do so could
cause an accident resulting in death or serious injury.
Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded.
(P. 245)
Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while
descending steep or long downhill grades.
Operation of the brake pedal
Do not hold the brake pedal depressed often or for long periods of time.
Doing so may result in the brake overheating or reduce braking effects.
To avoid accident or injury
Do not use cruise control when you are towing.
Do not tow the vehicle with the compact spare tire installed.
NOTICE
Do not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle's electrical system
and cause a malfunction.

When the steering lock cannot be released
Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
If the system is malfunctioning
P. 600
If the electronic key battery is depleted
P. 529
Operation of the engine switch
When operating the engine switch, one short, firm press is enough. If the
switch is pressed improperly, the engine may not start or the engine switch
mode may not change. It is not necessary to press and hold the switch.
If attempting to restart the engine immediately after turning the engine
switch off, the engine may not start in some cases. After turning the engine
switch off, please wait a few seconds before restarting the engine.
If the smart entry & start system has been deactivated in a customized
setting
P. 670 Vehicles without a multi-information dis-
play: The smart entry & start system indi-
cator light (green) will flash quickly.
Vehicles with a multi-information display:
“Steering Lock active” will be displayed on
the multi-information display.
Check that the shift lever is set in P (Multi-
drive). Press the engine switch while turn-
ing the steering wheel left and right.
