nThe meters and display illuminate when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The engine switch is in IGNITION ON mode.
n When disconnecting and reco nnecting battery terminals
The following information data will be reset:
l Average fuel consumption
l Driving range
l Average vehicle speed
CAUTION
n 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.
n 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
nTo prevent damage to the engine and its components
lDo not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
l The engine may be overheating if the high engine coolant temperature
warning light comes on. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 543)

Electronic key battery depletion (vehicles with a smart key system)
lThe standard battery life is 1 to 2 years.
l If the battery becomes low, an alarm will sound in the cabin when the engine
stops. ( P. 504, 515)
l As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( P. 469)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
l To avoid serious deterioration, do not leave the electronic key within 3 ft. (1
m) of the following electrical appl iances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
n Replacing the battery
P. 469
n Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask
your Toyota dealer for details.
n If a wrong key is used (vehicles with a smart key system)
The key cylinder rotates freely to isolate inside mechanism.

that generates strong radio waves
l When carrying a portable radio, cellular phone or other wireless communi-
cation devices

(Customizable features: P. 576)
CAUTION
nTo 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.
lAlways use a seat belt.
l Always lock all the doors.
l Ensure that all doors are properly closed.
l 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.
Be especially careful for the front doors, as the doors may be opened
even if the inside lock buttons are in locked position.
l Set the rear door child-protector locks when children are seated in the rear
seats.

1203-2. Opening, closing and locking the doors
COROLLA_TMMMS_TMMC_U (OM12J84U)n
Note for the entry function
lEven when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to
the rear bumper center when the trunk is opened.
• The electronic key is on the instrument panel, rear package tray or floor, or in the door pockets or glove box when the engine is started or engine
switch modes are changed.
l Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
doors will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
l As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
l Even if the electronic key is not inside the vehicle, it may be possible to start
the engine if the electronic key is near the window.
l The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash, when the electronic key is
within the effective range. (The doors will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
l If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)
l Touching the door lock or unlock sensor while wearing gloves may prevent
lock or unlock operation.
l When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
l If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart key
system. ( P. 118)
l Vehicles with a drive monitor display: If the electronic key is inside the vehi-
cle and a door handle becomes wet during a car wash, a buzzer will sound
outside the vehicle. To turn off the alarm, lock all the doors.

1744-2. Driving procedures
COROLLA_TMMMS_TMMC_U (OM12J84U)n
When the smart key system indicator light flashes in yellow (vehicles
with a drive monitor display)
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.
n When “CHECK SMART KEY SYSTEM” will be displayed on the multi-
information display (vehicles with a multi-information display)
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.
n If the electronic key battery is depleted
P. 469
n Operation of the engine switch
lWhen 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.
l 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.
n If the smart key system has been deactivated in a customized setting
P. 535
CAUTION
nWhen starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
n Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting in
death or serious injury.
n Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 2 seconds, or press it briefly
3 times or more in succession. ( P. 489)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine 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.

1944-3. Operating the lights and wipers
