3-2. Opening, closing and locking the doors
■Note for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
● 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.
● If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. Place the key in a posi-
tion 6 ft. (2 m) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)
● 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 dis-
play 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.
● 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.
■ Notes for the unlocking function
●Gripping the front door handle when wearing a glove may not unlock or lock
the door.
● A sudden approach to the effective range or door handle operation may pre-
vent the doors from being unlocked. In this case, return the door handle to
the original position and check that the doors have unlocked before pulling
the door handle.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after one of the front door handles is gripped or
one of sliding door handles is pulled.
■ 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. 627)

■Daytime running light system (if equipped)
●Bulb type: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically whenever the
engine is started and the parking brake is released with the headlight switch
off or in the “AUTO” position. (illuminate dimmer than the headlights) Day-
time running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
LED type: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically whenever the
engine is started and the parking brake is released with the headlight
switch off. Daytime running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

Driving
●In the situations below, the system may not be able to correctly detect the
surrounding brightness levels, and may flash or expose nearby pedestrians
to the high beam. Therefore, you should consider turning the high beam on
or off manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights
or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are changing color, or are not aimed properly.
• When driving through an area of in termittently changing brightness and
darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is lifting or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
• The driver believes that the high beam may be causing problems or dis- tress to other drivers or pedestrians nearby.
