421-1. For safe use
4RUNNER (U)_(OM35B46U)■
SRS airbag deployment conditions (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] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
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 collision in which the front of the vehicle “underrides”, or goes under, the bed of a
truck
● Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.
● The SRS front airbags for the front passenger will not activate if there is no
passenger sitting in the front passenger seat. However, the SRS front air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied.
■ SRS airbag deployment conditions (S RS side and curtain shield airbags)
● The SRS side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 3300 lb. [1500 kg] vehi\
cle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).
● The SRS curtain shield airbags will deploy in the event of vehicle rollover.
● The SRS side and curtain shield airbags will deploy in the event of a severe
frontal collision.

4RUNNER (U)_(OM35B46U)■
Conditions under which the SRS airbags may deploy (inflate), other than
a collision
The SRS front airbags, SRS side and curtain shield airbags may also deploy
if a serious impact occurs to the underside of your vehicle. Some examples
are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situations shown
in the illustration.
■ Types of collisions that may not de ploy the SRS airbags (SRS front air-
bags)
The SRS front airbags do not generally inflate if the vehicle is involved in a
side or rear collision, if it rolls over, or if it is involved in a low-speed frontal
collision. But, whenever a collision of any type causes sufficient forward
deceleration of the vehicle, deployment of the SRS front airbags may occur. ● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or falling
● The angle of vehicle tip-up is marginal.
● The vehicle skids and hits a curb stone.
● Collision from the side
● Collision from the rear
● Vehicle rollover

Front passenger occupant classification
system
Your vehicle is equipped with a front passenger occupant classi-
fication system. This system detects the conditions of the front
passenger seat and activates or deactivates the devices for the
front passenger.

Operation of each component
4RUNNER (U)_(OM35B46U)■
If you lose your keys
New genuine keys can be made by your Toyota dealer using the other key
(vehicles without a smart key system) or mechanical key (vehicles with a
smart key system) and the key number stamped on your key number plate.
Keep the plate in a safe place such as your wallet, not in the vehicle.
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircraft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to
emit radio waves that could interfere with the operation of the aircraft.
■ Conditions affecting operation
Vehicles without a smart key system
The wireless remote control function may not operate normally in the follow-
ing situations:
● Near a TV tower, radio station, electric power plant, airport or other facility
that generates strong radio waves
● When carrying a portable radio, cellul ar phone or other wireless communi-
cation devices
● When multiple wireless keys are in the vicinity
● When the wireless key is in contact with, or is covered by, a metallic object
● When a wireless key (that emits radio waves) is being used nearby
● When the wireless key has been left near an electrical appliance such as a
personal computer
Vehicles with a smart key system

Operation of each component
4RUNNER (U)_(OM35B46U)■
Battery-saving function
The battery-saving function will be activated in order to prevent the electronic
key battery and the vehicle battery from being discharged while the vehicle is
not in operation for a long time.
●In the following situations, the smart key system may take some time to
unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of
the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.
● If the smart key system has not been used for 14 days or longer, the doors
cannot be unlocked at any doors except the driver’s door. In this case, take
hold of the driver’s door handle, or use the wireless remote control or the
mechanical key, to unlock the doors.
The system will resume operation when
● The vehicle is locked using the door handle lock switch when carrying the
electronic key on your person.
● The vehicle is locked/unlocked using the wireless remote control.
(→P. 97)
● The vehicle is locked/unlocked using the mechanical key. ( →P. 451)
■ Conditions affecting operation
The smart key system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and engine immobi-
lizer system from operating properly. (Ways of coping: →P. 451)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
● When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device

The engine switch was
pressed after the doors
were unlocked with the
mechanical key.
Touch the electronic
key to the engine

the brake pedal.
The engine switch was
pressed two consecu-
tive times without the
electronic key being
present.
AlarmSituationCorrection procedure

1864-1. Before driving
4RUNNER (U)_(OM35B46U)
●Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making
turn.
● Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slippery
surfaces, etc.
Increasing vehicle speed c an destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehi cle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in
D.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when driving
up a long or steep grade. If t he engine coolant temperature gauge
indicates overheating, immediately turn off the air conditioning (if in
use), pull your vehicle off the road and stop in a safe spot.
