2023 TOYOTA HIGHLANDER gas type

361-1. For safe use
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.
●All of the doors will be unlocked.
(  P.116)
●The brakes and st op lights will be
controlled automatically. ( P.308)
●The interior lights will turn on auto-
matically. ( P.339)
●The emergency flashers will turn
on automatically. ( P.424)
●Fuel supply to the engine will be
stopped. (P.430)
●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. 6 5 )
• 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
●Depending on the type of collision,
it is possible that only the seat belt
pretensioners and SRS seat cush-
ion airbag will activate.

WARNING
■When refueling the vehicle
Observe the following precautions
while refueling the vehicle. Failure
to do so may result in death or
serious injury.
●After exiting the vehicle and
before opening the fuel door,
touch an unpainted metal sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing from static electricity can
cause fuel vapors to ignite while
refueling.
●Always hold the grips on the
fuel tank cap and turn it slowly
to remove it.
A whooshing sound may be
heard when the f uel tank cap is
loosened. Wait until the sound
cannot be heard before fully
removing the cap. In hot
weather, pressurized fuel may
spray out of the filler neck and
cause injury.
●Do not allow anyone that has
not discharged static electricity
from their body to come close to
an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that
are harmful if inhaled.
●Do not smoke while refueling
the vehicle.
Doing so may cause the fuel to
ignite and cause a fire.
●Do not return to the vehicle or
touch any person or object that
is statically charged.
This may cause static electricity
to build up, resulting in a possi-
ble ignition hazard.
■When refueling
Observe the following precautions
to prevent fuel overflowing from
the fuel tank:
●Securely insert the fuel nozzle
into the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.

Maintenance and care
Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■Shampooing the carpets
There are several commercial foam-
ing-type cleaners available. Use a
sponge or brush to apply the foam.
Rub in overlapping circles. Do not
use water. Wipe dirty surfaces and
let them dry. Excellent results are
obtained by keeping the carpet as
dry as possible.
■Handling the seat belts
Clean with mild soap and lukewarm
water using a cloth or sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.

When trouble arises
traffic.
■When the battery is removed or
discharged
●Information stored in the ECU is
cleared. When the battery is
depleted, have the vehicle
inspected at you r Toyota dealer.
●Some systems may require initial-
ization. ( P.507)
■When removing the battery ter-
minals
When the battery terminals are
removed, the information stored in
the ECU is cleared . Before remov-
ing the battery terminals, contact
your Toyota dealer.
■Charging the battery
The electricity stor ed in the battery
will discharge gradu ally even when
the vehicle is not i n use, due to nat-
ural discharge and the draining
effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the battery may discharge,
and the engine ma y be unable to
start. (The battery recharges auto-
matically during driving.)
■After jump starting the vehicle
(Vehicles with Stop & Start sys-
tem)
Be sure to disable the Stop & Start
system so that the battery can be
charged. ( P.265)
■When recharging or replacing
the battery
●In some cases, i t may not be pos-
sible to unlock the doors using the
smart key system when the bat-
tery is discharged. Use the wire-
less remote control or the
mechanical key to lock or unlock
the doors.
●The engine may not start on the
first attempt after the battery has
recharged but will start normally
after the se cond attempt. This is
not a malfunction.
●The engine switch mode is memo- rized by the vehicle. When the
battery is reconnected, the system
will return to the mode it was in
before the bat
tery was dis-
charged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the
engine switch wa s in before the
battery discharged, be especially
careful when reconnecting the
battery.
●Vehicles with power back door:
The power back door must be ini-
tialized. ( P.127)
●Vehicles with Stop & Start system:
The Stop & Start system may not
automatically stop the engine for
up to an hour.
■When replacing the battery
●Use a Central Degassing type bat-
tery (European Regulations).
●Vehicles with Stop & Start system:
Use a genuine battery specifically
designed for use with the Stop &
Start system or a battery with
equivalent specifications to a gen-
uine battery. If an unsupported
battery is used, Stop & Start sys-
tem functions may be restricted to
protect the battery.
Also, battery per formance may
decrease and the engine may not
be able to restart. Contact your
Toyota dealer for details.
●Vehicles without Stop & Start sys-
tem: Use a battery that the case
size is same as the previous one
(LN3), 20 hour rate capacity
(20HR) is equivalent (70Ah) or
greater, and per formance rating
(CCA) is equivalent (603A) or
greater.
Vehicles with Stop & Start system:
Use a battery that the case size is
same as the previous one (LN3), 20
hour rate capacity (20HR) is equiva-
lent (65Ah) or greater, and perfor-
mance rating (CCA) is equivalent
(603A) or greater.
• If the sizes differ, the battery can- not be properly secured.
