WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that must be paid to
the area in front of the vehicle.
The driver must always assume
full responsibility for driving
safely by paying careful atten-
tion to the surrounding condi-
tions and operating the steering
wheel to correct the path of the
vehicle. Also, the driver must
take adequate breaks when
fatigued, such as from driving
for a long period of time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident, resulting in death or
serious injury.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Vehicle is driven on a road sur-
face which is slippery due to
rainy weather, fallen snow,
freezing, etc.
●Vehicle is driven on a snow-cov-
ered road.
●White (yellow) lines are difficult
to see due to rain, snow, fog,
dust, etc.
●Vehicle is driven in a temporary
lane or restricted lane due to
construction work.
●Vehicle is driven in a construc-
tion zone.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been
excessively worn, or when the
tire inflation p ressure is low.
●When your vehicle is towing a
trailer or during emergency tow-
ing.
■Preventing LTA system mal-
functions and operations per-
formed by mistake
●Do not modify the headlights or
place stickers, etc. on the sur-
face of the lights.
●Do not modify the suspension
etc. If the suspension etc. needs
to be replaced, contact your
Toyota dealer.

the steering wheel to correct the
path of the vehicle without relying
solely on the functions.

4026-1. Maintenance and care
HIGHLANDER HV_U
NOTICE
●If the paint is chipped or
scratched, have it repaired
immediately.
●To prevent the wheels from cor-
roding, remove any dirt and
store in a place with low humid-
ity when storing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use
organic substances or scrub
with a hard brush.
This may damage the surfaces
of the lights.
●Do not apply wax to the sur-
faces of the lights.
Wax may cause damage to the
lenses.
■When using an automatic car
wash (vehicles with
rain-sensing windshield wip-
ers)
Set the wiper switch to the off
position.
If the wiper switch is in “AUTO”,
the wipers may operate and the
wiper blades may be damaged.
■When using a high pressure
car wash
●When washing the vehicle, do
not spray the came ra or its sur-
rounding area directly with a
high pressure washer. Shock
applied from high pressure
water may cause the device to
not operate normally.
●Do not spray water directly on
the radar which is equipped
behind the emblem. Otherwise
it may cause the device to be
damaged.
●Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicle body. Otherwise
resin section, s uch as moldings
and bumpers, may be deformed
and damaged.
Also, do not continuously hold the
nozzle in the same place.
●Do not spray the lower part of
the windshield continuously.
If water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.
●Do not wash the underside of
the vehicle using a high pres-
sure car washer.
