For safety and security
HIGHLANDER_U
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls airbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo -
nents diagram above. This informat ion includes crash severity and
occupant information. As the airbags deploy, a chemical reactio n in
the inflators quickly fills the airbags with non-toxic gas to h elp restrain
the motion of t he occupants.
WARNING
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
● The driver and all passengers in the vehicle must wear their se at belts
properly.
The SRS airbags are supplemental devices to be used with the se at belts.
● The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
The National Highway Traffic Safety Administration (NHTSA) advi ses:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of inflation, placing yourself 10 in. (250 mm) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measured from
the center of the steering wheel to your breastbone. If you sit less than 10
in. (250 mm) away now, you can change your driving position in several
ways:
• Move your seat to the rear as far as you can while still reach ing the ped-
als comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 10 in. (250
mm) distance, even with the driver seat all the way forward, si mply by
reclining the back of the seat somewhat. If reclining the back of your
seat makes it hard to see the road, raise yourself by using a f irm, non-
slippery cushion, or raise the seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the air-
bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, whil e
still maintaining control of the foot pedals, steering wheel, and your view
of the instrument panel controls.

Operation of each component
HIGHLANDER_U
NOTICE
■To prevent back door closer malfu nction (vehicles with a power back
door)
Do not apply excessive force to the back door while the back door closer is
operating.
■ To prevent damage to the po wer back door (if equipped)
● Make sure that there is no ice between the back door and frame that
would prevent movement of the back door. Operating the power ba ck door
when excessive load is present on the back door may cause a mal func-
tion.
● Do not apply excessive force to the back door while the power b ack door
is operating.
● Take care not to damage the sensors (installed on the right and left edges
of the power back door) with a knife or other sharp object. If the sensor is
disconnected, the power back door will not close automatically.

1753-4. Adjusting the steering wheel and mirrors

Operation of each component
HIGHLANDER_U
Auto anti-glare inside rear view mirror
Responding to the level of brightness of the headlights of vehi cles
behind, the reflected light is automatically reduced.
Changing automatic anti- glare 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 IGNITION ON mode.
Pressing the button turns the func-
tion to OFF mode. (The indicator
also turns off.)

■ To prevent sensor error (vehicles with an auto anti-glare insid e 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.

WARNING
■ To avoid malfunction of the radar sensor
Observe the following precautions.
Otherwise, the radar sensor may not operate properly, possibly leading to
an accident resulting in death or serious injury.
● Keep the radar sensor and front g rille emblem clean at all times.
● Do not attach accessories, stickers (including transparent stic kers) or
other items to the radar sensor, front grille emblem or surroun ding area.
● Do not subject the radar sensor or surrounding area to a strong impact.
If the radar sensor, front grille, or front bumper has been sub jected to a
strong impact, have the vehicle inspected by your Toyota dealer .
● Do not disassemble the radar sensor.
● Do not modify or paint the radar sensor, front grille emblem or surrounding
area.
● If the radar sensor, front grille, or front bumper needs to be removed and
installed, or replaced, contact your Toyota dealer.
Radar sensor
Front grille emblem
If the front of the radar sensor or the
front or back of the front grille emblem
is dirty or covered with water droplets,
snow, etc., clean it.
Clean the radar sensor and front grille
emblem with a soft cloth so you do not
mark or damage them.1

The Blind Spot Monitor is a system that has 2 functions:
● The BSM (Blind Spot Monitor) function
Assists the driver in making a decision when changing lanes
● The RCTA (Rear Cross T raffic Alert) function
Assists the driver when backing up
These functions use same sensors.

WARNING
■Handling the radar sensor
Blind Spot Monitor sensors are installed behind the left and ri ght sides of the
rear bumper respectively. Observe the following to ensure the B lind Spot
Monitor can function correctly.
● Do not subject a sensor or its surrounding area on the rear bum per to a
strong impact.
If a sensor is moved even slightly off position, the system may malfunction
and vehicles may not be detected correctly.
In the following situations, have your vehicle inspected by your Toyota
dealer.
• A sensor or its surrounding area is subject to a strong impact .
• If the surrounding area of a sensor is scratched or dented, or part of
them has become disconnected.
● Do not disassemble the sensor.
● Do not attach stickers to the sensor or surrounding area on the rear
bumper.
● Do not modify the sensor or surrounding area on the rear bumper .
● Do not paint the rear bumper any color other than an official Toyota color.
●Keep the sensors and the surrounding
areas on the rear bumper clean at all
times.
If a sensor or its surrounding area on
the rear bumper is dirty or covered with
snow, the Blind Spot Monitor may not
operate and a warning message ( P.
593) will be displayed. In this situation,
clear off the dirt or snow and drive the
vehicle with the operation conditions of
the BSM function ( P. 329) satisfied for
approximately 10 minutes. If the warn-
ing message does not disappear, have
the vehicle inspected by your Toyota
dealer.

HIGHLANDER_U
The BSM function uses radar sensors to detect vehicles that are trav-
eling in an adjacent lane in the area that is not reflected in the outside
rear view mirror (the blind spot), and advises the driver of th e vehicles
existence via the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to: Approximately 11.5 ft. (3.5 m)
from the side of the vehicle
The first 1.6 ft. (0.5 m) from the
side of the vehicle is not in the
detection area
Approximately 9.8 ft. (3 m) from
the rear bumper
Approximately 3.3 ft. (1 m) for-
ward of the rear bumper

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a
vehicle is in a blind spot of the outside rear view mirrors or is approaching
rapidly from behind into a blind spot. Do not overly rely on th e BSM function.
As the function cannot judge if it is safe to change lanes, ove r reliance could
lead to an accident resulting in death or serious injury.
As the system may not function correctly under certain conditions, the
driver’s own visual confirmation of safety is necessary.
