1323-2. Opening, closing and locking the doors and trunk
IS250_EE(OM53C51E)
■Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless remote control and engine immobilizer system
from operating properly. (Ways of coping: →P. 5 2 4 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, airport or
other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless com-
munication device
●When the electronic key is in contact with, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that emit radio waves) are being used nearby
●When carrying the electronic key together with the following devices that emit radio
waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear win-
dow

Operation of each component
IS250_EE(OM53C51E)
■Note for the entry function (if equipped)
●Even 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.
●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 reception 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.
●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 electronic key can be used
to unlock the vehicle.
●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 30 seconds if the doors
are not opened and closed.)
●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 func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock or unlock sensor while wearing gloves may prevent lock or
unlock operation.
●If the door handle becomes wet while the electronic key is within the effective 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 2 m (6 ft.) 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 entry & start sys-
tem. (→P. 131)
●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, or use the lock sensor on the
lower part of the door handle.
●A sudden handle operation or a handle operation immediately after entering the effec-
tive 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 effec-
tive range.

IS250_EE(OM53C51E)
■Note for the push-start function
●Even when the electronic key is within the effective range (detection areas), the system
may not operate properly when 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.
●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.
■When the vehicle is not driven for extended periods
●Vehicles with entry function: To prevent theft of the vehicle, do not leave the electronic
key within 2 m (6 ft.) of the vehicle.
●The smart entry & start system can be deactivated in advance. (→P. 551)
■To operate the system properly
●Make sure to carry the electronic key when operating the system. Do not get the elec-
tronic key too close to the vehicle when operating the system from the outside of the
vehicle.
Depending on the position and holding condition of the electronic key, the key may not
be detected correctly and the system may not operate properly. (The alarm may go off
accidentally, or the door lock prevention function may not operate.)
●Do not leave the electronic key inside the luggage compartment.
The key confinement prevention function may not operate, depending on the location
of the key (close to a spare tire [if equipped], the inside edge of the luggage compart-
ment), conditions (inside a metal bag, close to metallic objects) and the radio waves in
the surrounding area. (→P. 1 2 7 )
■If the smart entry & start system does not operate properly
●Locking and unlocking the doors and opening the trunk: Use the mechanical key.
(→P. 5 2 4 )
●Starting the engine: →P. 5 2 5
■Customization
Settings (e. g. smart entry & start system) can be changed.
(Customizable features: →P. 551)
■If the smart entry & start system has been deactivated in a customized setting
●Locking and unlocking the doors and opening the trunk:
Use the wireless remote control or mechanical key. (→P. 118, 126, 524)
●Starting the engine and changing engine switch modes: →P. 5 2 5
●Stopping the engine: →P. 1 9 2

1653-4. Adjusting the steering wheel and mirrors
3
Operation of each component
IS250_EE(OM53C51E)
When either “L” or “R” of the mirror select switch is selected, the outside rear
view mirrors will automatically angle downwards when the vehicle is reversing in
order to give a better view of the ground.
To disable this function, select neither “L” nor “R”.
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired position.
The adjusted angle will be memorized and the mirror will automatically tilt to
the memorized angle whenever the shift lever is shifted to R from next time.
The memorized downward tilt position of the mirror is linked to the normal position
(angle adjusted with the shift lever in other than R). Therefore, if the normal posi-
tion is changed after adjustment, the tilt position will also change.
When the normal position is changed, readjust the angle in reversing.
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. (→P. 3 8 2 )
■Automatic adjustment of the mirror angle (if equipped)
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. (→P. 1 5 1 )
■Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror is set to automatic mode, the outside rear
view mirrors will activate in conjunction with the anti-glare inside rear view mirror to
reduce reflected light. (→P. 1 6 2 )
■Using automatic mode in cold weather
When automatic mode is used in cold weather, the door mirror could freeze up and
automatic stowing and return may not be possible. In this case, remove any ice and snow
from the door mirror, then either operate the mirror using manual mode or move the mir-
ror by hand.
■Customization
The automatic mirror folding and extending operation can be changed. (Customizable
features: →P. 5 5 1 )
Linked mirror function when reversing (if equipped)
