NOTICE
Hybrid battery air vent
Do not put foreign objects over or in
front of the air vent. The hybrid battery
(traction battery) may overheat and be
damaged.
Clean the air vent regularly to prevent
the hybrid battery (traction battery) from
overheating.
Do not wet or allow foreign substances
to enter the air vent as this may cause a
short circuit and damage the hybrid bat-
tery (traction battery).
Do not carry large amounts of water
such as water cooler bottles in the vehi-
cle. If water spills onto the hybrid bat-
tery (traction battery), the battery may
be damaged.

CAUTION
Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Inhaling exhaust gases may lead to death or a serious health
hazard.
Except hybrid vehicle: If the vehicle is in a poorly ventilated area, stop the
engine. In a closed area, such as a garage, exhaust gases may collect
and enter the vehicle. This may lead to death or a serious health hazard.
Hybrid vehicle: If the vehicle is in a poorly ventilated area, stop the hybrid
system. In a closed area, such as a garage, exhaust gases may collect
and enter the vehicle. This may lead to death or a serious health hazard.
The exhaust system should be checked occasionally. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise,
be sure to have the vehicle inspected and repaired by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional. Failure to do so may allow exhaust gases to enter the vehicle,
resulting in death or a serious health hazard.
When taking a nap in the vehicle
Except hybrid vehicle: Always turn the engine off. Otherwise, if you acci-
dentally 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 vehicle: Always turn the hybrid system off. Otherwise, if you acci-
dentally 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 col-
lect and enter the vehicle, leading to death or a serious health hazard.

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.
When the smart entry & start system indicator light flashes in yellow
The system may be malfunctioning. Have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional immediately.
If the electronic key battery is depleted
P. 501
Operation of the “ENGINE START STOP” switch
When operating the “ENGINE START STOP” switch, one short, firm press is
enough. If the switch is pressed improperly, the engine may not start or the
“ENGINE START STOP” switch mode may not change. It is not necessary to
press and hold the switch.
If the smart entry & start system has been deactivated in a customized
setting
P. 679

Notes for the entry function
P. 7 9
If the hybrid system does not start
The immobilizer system may not have been deactivated. (P. 155)
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional.
Steering lock
After turning the “POWER” switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
“POWER” switch again automatically cancels the steering lock.
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 hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system. After about 10
seconds, the steering lock motor will resume functioning.
Check that the shift lever is securely set
in P. The hybrid system may not start if
the shift lever is displaced out of P. The
smart entry & start system indicator light
(green) will flash quickly.

Shift position purpose
*: To improve fuel efficiency and reduce noises, set the shift lever in the D
position for normal driving.
Selecting Eco drive mode
Suitable for improving the fuel economy, because the torque cor-
responding to the accelerator pedal depression amount can be
generated more smoothly than it is in normal conditions and the
operation of the air conditioning system (heating/cooling) will be
minimized.
Eco drive mode
When Eco drive mode is
turned on, the “ECO MODE”
indicator will come on.
Pressing the “ECO MODE”
switch again turns Eco drive
mode off.

Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. (P. 366) To improve air
conditioning performance, adjust the temperature setting or fan speed, or
turn off Eco drive mode.
When in heavy traffic
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid putting the shift
lever in N for an extended period of time.
If the shift lever cannot be shifted from P
P. 613
CAUTION
When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.

Parking brake
Usage in winter time
P. 336
NOTICE
Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components
overheating, which may affect braking performance and increase brake
wear.
To set the parking brake,
fully pull the parking brake
lever while depressing the
brake pedal.
To release the parking
brake, slightly raise the
lever and lower it com-
pletely while pressing the
button.

NOTICE
To prevent damage to the engine and its components
Vehicles with a tachometer: Do not let the indicator needle of the tachome-
ter enter the red zone, which indicates the maximum engine speed.
The engine may be overheating if the high engine coolant temperature
warning light flashes or turns on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.
