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 aga in.
● When the lock operation is performed using the lock sensor, rec ognition 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 with in 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 ve hicle 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 b ecomes wet
during a car wash, a message may be shown on the multi-informat ion dis-
play and a buzzer will sound outside the vehicle. To turn off t he 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 un locking function
● Gripping the front door handle when wearing a glove may not unl ock or lock
the door.
● A sudden approach to the effective range or door handle operati on may pre-
vent the doors from being unlocked. In this case, return the do or handle to
the original position and check that the doors have unlocked be fore pulling
the door handle.
● If there is another electronic key in the detection area, it ma y 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 ke y within 6 ft.
(2 m) of the vehicle.
● The smart key system can be deactivated in advance. ( P. 544)

function mode
On/off
When the automatic anti-glare
function is in on mode, the indica-
tor illuminates.
The function will set to on mode
each time the engine switch is
turned to “ON” position (vehicles
without a smart key system) or
IGNITION ON mode (vehicles with
a smart key system).
Pressing the button turns the function to off mode. (The indica tor also turns
off.)
■ To prevent sensor error (vehicles with auto anti-glare inside rear view
mirror)
Indicator
To ensure that the sensors operate prop-
erly, do not touch or cover them.
WARNING
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and cause an ac cident,
resulting in death or serious injury.

4-3. Operating the lights and wipers
■Daytime running light system (if equipped)
●Bulb type: The daytime running lights illuminate using the same lights as the
headlights and illuminate dimmer than the headlights.
● LED type: The daytime running lights illuminate using the same lights as the
parking lights and illuminate brighter than the parking lights.
● To make your vehicle more visible to other drivers during dayti me driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designe d for use at
night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the (Canada only), or “AUTO”
*
position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking
brake is set again.
● For the U.S.A.: Daytime running lights can be turned off by ope rating the
headlight switch.
● Compared to turning on the headlights, the daytime running ligh t 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.

Automatic High Beam
Push the lever away from you with
the headlight switch in the
position.
The Automatic High Beam indica-

lights are turned on automatically
to indicate that the system is
active.
When all of the following conditions are fulfilled, high beam will be
automatically turned on (after approximately 1 second):
● Vehicle speed is above appr oximately 20 mph (32 km/h).
● The area ahead of the vehicle is dark.
● There are no oncoming or precedi ng vehicles with headlights or tail
lights turned on.
If any of the following conditions are fulfilled, high beam wil l be auto-
matically turned off:
● Vehicle speed drops below app roximately 20 mph (32 km/h).
● The area ahead of the vehicle is not dark.
● Oncoming or preceding vehicles have headlights or tail lights
turned on.
The Automatic High Beam uses an in-vehicle camera sensor to
assess the brightness of streetli ghts, the lights of oncoming and
preceding vehicles, etc., and au tomatically turns high beam on
or off as necessary.

■ Camera sensor detection information
●High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve.
• When the vehicle is cut in front of by another.
● High beam may be turned off if an oncoming vehicle that is usin g fog lights
without using the headlights is detected.
● Houselights, streetlights, red traffic signals, and illuminated billboards or
signs may cause the high beam to turn off.
● The following factors may affect the amount of time taken to tu rn high beam
on or off:
• The brightness of headlights, fog lights, and tail lights of o ncoming and
preceding vehicles
• Road conditions (wetness, ice, snow etc.)
• The number of passengers and amount of baggage
● High beam may be turned on or off when unexpected by the driver .

Driving
●In the situations below, the system may not be able to correctl y detect the
surrounding brightness levels, and may flash or expose nearby p edestrians
to the high beam. Therefore, you should consider turning the hi gh 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, d irty, are
changing color, or are not aimed properly.
• When driving through an area of intermittently 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 w inding
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 betwe en in
an abnormal manner.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.
■ Customization
The Automatic High Beam can be turned off.
