■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 s ubject to inter-
ference by artificial magnetic fields (underground car park/par king 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 mi rror.)
● 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 veh icle 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 performin g circling cali-
bration.
NOTICE
■ To avoid compass malfunctions
Do not place magnets or any metal objects near the inside rear view mirror.
Doing this may cause the compass sensor to malfunction.
■ To ensure normal operation of the compass
● Do not perform circling calibration of the compass in a place w here the
earth's magnetic field is subject to interference 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
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 unti l it has
cooled sufficiently, as touching a hot exhaust pipe can cause b urns.
■ Precaution regarding the rear bumper with Blind Spot Monitor (i f
equipped)
If the paint of the rear bumper is chipped or scratched, the sy stem 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.
