Airbag sensor assembly
Your vehicle is equipped wi th ADVANCED AIRBAGS designed 
based on the US motor vehicle safety standards (FMVSS208). The 
airbag sensor assembly (ECU) controls airbag deployment based on 
information obtained from the sensors etc. shown in the system 
components diagram above. This information includes crash sever-
ity and occupant information. As the airbags deploy, a chemical 
reaction in the inflators quickly fills the airbags with non-toxic gas to 
help restrain the motion of the occupants.
■If the SRS airbags deploy 
(inflate)
●Slight abrasions, burns, bruising 
etc., may be sustained from SRS 
airbags, due to the extremely high 
speed deployment (inflation) by 
hot gases.
●A loud noise and white powder will 
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and 
inflator) as well as the front seats, 
parts of the front  and rear pillars, 
and roof side rails, may be hot for 
several minutes. The airbag itself 
may also be hot.
●The windshield may crack.
●The interior lights will turn on auto-
matically. ( P.401)
●The emergency flashers will be 
turned on automatically. ( P.464)
●For Safety Connect subscribers, if 
any of the following situations 
occur, the system is designed to 
send an emergency call to the 
response center, notifying them of 
the vehicle’s location (without 
needing to push the “SOS” button) 
and an agent will a ttempt to speak 
with the occupants to ascertain 
the level of emergency and assis-
tance required. If the occupants 
are unable to communicate, the 
agent automatically treats the call  as an emergency and helps to dis-
patch the necessary emergency 
services. (
P. 5 8 )
• An SRS airbag is deployed.
• A seat belt pretensioner is acti- vated.
• The vehicle is involved in a severe  rear-end collision.
■SRS airbag deployment condi-
tions (SRS front airbags)
●The SRS front airbags will deploy 
in the event of an impact that 
exceeds the set threshold level 
(the level of force corresponding 
to an approximately 12 - 18 mph 
[20 - 30 km/h] fr ontal collision with 
a fixed wall that does not move or 
deform).
However, this threshold velocity will 
be considerably higher in the follow-
ing situations:
• If the vehicle strikes an object,  such as a parked vehicle or sign 
pole, which can move or deform 
on impact
• If the vehicle is involved in an 
underride collision,  such as a colli-
sion in which the front of the vehi-
cle “underrides”, or goes under, 
the bed of a truck
●Depending on the type of collision, 
it is possible that only the seat belt 
pretensioners will activate.
●The SRS front airbags for the front 
passenger will not activate if there

■Note for the entry function
●Even when the electronic key is 
within the effective range (detec-
tion areas), the system may not 
operate properly in the following  cases:
• The electronic key is too close to  the window or outside door han-
dle, near the ground, or in a high 
place when the doors are locked 
or unlocked.
• The electronic key is on the instru- ment panel, luggage cover or

glove box when the engine is 
started or engine switch modes 
are changed.
●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 out-
side the cabin and the door 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.
●Even if the electronic key is not 
inside the vehicle, it may be possi-
ble to start the engine if the elec-
tronic key is near the window.
●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

Before driving
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals 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 effective range, the door may 
lock and unlock repeatedly. In that 
case, follow the fo llowing correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca-
tion 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 bat- tery-saving mode to disable the 
smart key system. ( P.109)
●If the electronic key is inside the 
vehicle and a door handle 
becomes wet during a car wash, a

Automatic High Beam
The Automatic High Beam 
uses a camera sensor 
located behind the upper 
portion of the windshield to 
assess the brightness of the 
lights of vehicles ahead, 
streetlights, etc., and auto-
matically turns the high 
beams on or off as neces-
sary.

• When vehicles ahead cannot be  detected due to repeated curves, 
road dividers or roadside trees
• When vehicles ahead appear in a  faraway lane on a wide road
• When the lights of vehicles ahead 
are not on
●The high beams may be turned off 
if a vehicle ahead that is using fog 
lights without its headlights turned 
on is detected.
●House lights, street lights, traffic 
signals, and illumi nated billboards 
or signs and other reflective 
objects may cause the high 
beams to change to the low 
beams, or the low beams to 
remain on.
●The following factors may affect 
the amount of time taken for the 
high beams to turn on or off:
• The brightness of the headlights,  fog lights, and tail lights of vehi-
cles ahead
• The movement and direction of  vehicles ahead
• When a vehicle ahead only has 
operational lights on one side
• When a vehicle ahead is a  two-wheeled vehicle

surface, etc.)
• The number of passengers and  amount of luggage in the vehicle
●The high beams may turn on or off 
unexpectedly.
●Bicycles or similar vehicles may 
not be detected.
●In the following situations the sys-
tem may not be able to correctly 
detect the surrounding brightness 
level. This may cause the low 
beams to remain on or the high 
beams to flash or dazzle pedestri-
ans or vehicles ahead. In such a 
case, it is necess ary to manually 
switch between the high and low 
beams. • When driving in inclement weather 
(heavy rain, snow, fog, sand-
storms, etc.)
