Airbag sensor assembly
Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) cont rols airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This in formation 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. T he airbag itself
may also be hot.
●The windshield may crack.
●The brakes and st op lights will be
controlled automatically. ( P.272)
●The interior lights will turn on auto-
matically. ( P.429)
●The emergency flashers will turn
on automatically. ( P.502)
●Fuel supply to the engine will be
stopped. (P.510)
●For Safety Connect subscribers, if
any of the followin g 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 attempt 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. 7 3 )
• 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 forc e corresponding
to an approximately 12 - 18 mph
[20 - 30 km/h] frontal 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

■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 near the ground or in a high place, or too
close to the center of the rear
bumper when the trunk is opened.
• The electronic key is on the instru- ment 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.
●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 unl ock 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
electronic key is w ithin the effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 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 possib ility that the door
may not be unlocked by the entry
function. (Use the wireless remote
control to unlock the doors.)
●If the doors have been locked
from outside of the vehicle and are
then not unlocked using the wire-
less remote control or smart key
system, the engine cannot be
started using the smart key sys-
tem. (However, if the doors have
been locked from i nside the vehi-
cle, the engine can be started
using the smart key system.)
If it is necessary to start the
engine, it can be started using the
procedure in “If the electronic key
dose not opera te properly”
(  P.545).
●Touching the door lock or unlock
sensor while wearing gloves may
prevent lock or unlock operation.
●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 following 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.127)
●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 vehi-
cle. To turn off the alarm, lock all

• When the vehicle is cut in front of by another vehicle
• 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, streetlights, 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 ta il 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
• The condition of the road (gradi-
ent, curve, condi tion of the road
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 abl e 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.)
• When the windshi eld is obscured
by fog, mist, ice, dirt, etc.
