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. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 536)

■ If you lose your keys
New genuine keys can be made by your Toyota dealer using the other key
(vehicles without a smart key system) or mechanical key (vehicles with a
smart key system) and the key number stamped on your key number plate.
Keep the plate in a safe place such as your wallet, not in the vehicle. 
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircraft,
make sure you do not press any button on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.  When   is pressed for longer than
about one second, an alarm will sound
intermittently and the vehicle lights will
flash to deter any person from trying to
break into or damage your vehicle.
To stop the alarm, press any button on the
wireless remote control.

CAUTION
■To prevent an accident
Observe the following precautions while driving the vehicle.
Failure to do so may result in a door opening and an occupant falling out,
resulting in death or serious injury.
● Always use a seat belt.
● Always lock all the doors.
● Ensure that all doors are properly closed.
● Do not pull the inside handle of the doors while driving. 
The doors may be opened and the passengers are thrown out of the vehi-
cle and it may result in serious injury or death.

CAUTION
■Caution while driving
● Keep the trunk lid closed while driving. 
If the trunk lid is left open, it may hit near-by objects while driving or lug-
gage in the trunk may be unexpectedly thrown out, causing an accident.
In addition, exhaust gases may enter the vehicle, causing death or a seri-
ous health hazard. Make sure to close the trunk lid before driving. 
● Before driving the vehicle, make sure that the trunk lid is fully closed. If the
trunk lid is not fully closed, it may open unexpectedly while driving, caus-
ing an accident.
● Never let anyone sit in the trunk. In the event of sudden braking or a colli-
sion, they are susceptible to death or serious injury. 
■ When a child is in the vehicle
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not allow a child to play in the trunk.
If a child is accidentally locked in the trunk, the child could suffer from heat
exhaustion, suffocation or other injuries.
● Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to operate unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing trunk lid.

Operation of each component
COROLLA_TMMMS_TMMC_U (OM12F00U)●
Vehicles with a multi-information display: If the electronic key is inside the
vehicle and a door handle becomes wet during a car wash, a message may
be shown on the multi-information display and a buzzer will sound outside
the vehicle. To turn off the alarm, lock all the doors.
● The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
● Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.
● A sudden handle operation or a handle operation immediately after entering
the effective range may prevent the doors from being unlocked. Touch the
door unlock sensor and check that the doors are unlocked before pulling the
door handle again.
● Unlocking the vehicle may take more time if another electronic key is within
the effective range.
■ When the vehicle is not driven for extended periods
●To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2
m) of the vehicle.
● The smart key system can be deactivated in advance. ( P. 570)
■ To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the
outside of the vehicle.

CAUTION
■Seat adjustment
● Be careful that the seat does not hit passengers or luggage.
● Do not recline the seat more than necessary when the vehicle is in motion
to reduce the risk of sliding under the lap belt. 
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
● Manual seat only: After adjusting the seat, make sure that the seat is
locked in position.
■ When adjusting the seat positions
Make sure to leave enough space around the feet so they do not get stuck.
