2017 TOYOTA HIGHLANDER HYBRID sensor

4406-1. Using the air conditioning system and defogger
HIGHLANDER_HV_U (OM48F12U)
WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
● Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers are on.
● Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on.
NOTICE
■Humidity sensor
■ To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed. ( →P. 439)
Follow these points to avoid damaging
the sensor:
● Do not disassemble the sensor
● Do not spray the glass cleaner on the
sensor or subject it to strong impacts
● Do not stick anything on the sensor

■Conditions unfavorable to correct operation
The compass may not show the correct direction in the following conditions:
●The vehicle is stopped immediately after turning.
● The vehicle is on an inclined surface.
● The vehicle is in a place where the earth's magnetic field is subject to inter-
ference by artificial magnetic fields (underground car park/parking lot, under
a steel tower, between buildings, roof car park/parking lot, near an intersec-
tion, near a large vehicle, etc.).
● The vehicle has become magnetized.
(There is a magnet or metal object near the inside rear view mirror.)
● The 12-volt battery has been disconnected.
● A door is open.
WARNING
■While driving the vehicle
Do not adjust the display. Adjust the display only when the vehicle is
stopped.
■ When doing the circling calibration
Secure a wide space, and watch out for people and vehicles in the neigh-
borhood. Do not violate any local traffic rules while performing circling cali-
bration.
NOTICE
■To avoid compass malfunctions
Do not place magnets or any metal objec ts near the inside rear view mirror.
Doing this may cause the compass sensor to malfunction.
■ To ensure normal op eration of the compass
● Do not perform circling calibration of the compass in a place where the
earth's magnetic field is subject to inte rference by artificial magnetic fields.
● During calibration, do not operate electric systems (moon roof, power win-
dows, etc.) as they may interfere with the calibration.

4927-1. Maintenance and care
HIGHLANDER_HV_U (OM48F12U)
WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
■ When cleaning the windshield (veh icles with rain-sensing windshield
wipers)
● When the upper part of the windshield where the raindrop sensor is
located is touched by hand
● When a wet rag or similar is held close to the raindrop sensor
● If something bumps against the windshield
● If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
■ Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has
cooled sufficiently, as touching a hot exhaust pipe can cause burns.
■ Precaution regarding the rear bumper with Blind Spot Monitor (if
equipped)
If the paint of the rear bumper is chipped or scratched, the system may mal-
function. If this occurs, consult your Toyota dealer.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in
hands being caught or other serious inju-
ries and cause damage to the wiper
blades.

sion System) will be enabled if the operational condi-
tions (such as temperature etc.) are met again.
When the warning light is illuminated:
Either the VSC (Vehicle Stability Control) system or PCS
(Pre-Collision system) is disabled or both are disabled.
