ABS TOYOTA HIGHLANDER 2021 (in English) User Guide

3244-5. Using the driving support systems
HIGHLANDER_Utions may be generated, but this is
not a malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sound (whirring
sound) may be heard. This does not
indicate a malfunction.
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the engine
off. The EPS system should return
to normal within 10 minutes.
■Automatic reactivation of
TRAC, Trailer Sway Control and
VSC systems
After turning the TRAC, Trailer
Sway Control and VSC systems off,
the systems will be automatically
re-enabled in the following situa-
tions:
●When the engine switch is turned
OFF
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when
vehicle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■Secondary Collision Brake
operating conditions
The system operates when the SRS
airbag sensor detects a collision
while the vehicle is in motion.
However, the system does not oper-
ate in any of the following situations.
●The vehicle speed is below 6 mph
(10 km/h)
●Components are damaged
■Secondary Collision Brake
automatic cancellation
The system is automatically can-
celed in any of the following situa-
tions.
●The vehicle speed drops below
approximately 6 mph (10 km/h)
●A certain amount of time elapses
during operation
●The accelerator pedal is
depressed a large amount
WARNING
■The ABS does not operate
effectively when
●The limits of tire gripping perfor-
mance have been exceeded
(such as excessively worn tires
on a snow covered road).
●The vehicle hydroplanes while
driving at high speed on wet or
slick roads.
■Stopping distance when the
ABS is operating may exceed
that of normal conditions
The ABS is not designed to
shorten the vehicle’s stopping dis-
tance. Always maintain a safe dis-
tance from the vehicle in front of
you, especially in the following sit-
uations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains

Driving
HIGHLANDER_U
WARNING
●When driving over bumps in the
road
●When driving over roads with
potholes or uneven surfaces
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Active Cornering Assist does
not operate effectively when
●Do not overly rely on Active
Cornering Assist. Active Corner-
ing Assist may not operate
effectively when accelerating
down slopes or driving on slip-
pery road surfaces.
●When Active Cornering Assist
frequently operates, Active Cor-
nering Assist may temporarily
stop operating to ensure proper
operation of the brakes, TRAC
and VSC.
■Hill-start assist control does
not operate effectively when
●Do not overly rely on hill-start
assist control. Hill-start assist
control may not operate effec-
tively on steep inclines and
roads covered with ice.
●Unlike the parking brake,
hill-start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.
■When the TRAC/VSC/Trailer
Sway Control is activated
The slip indicato r light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particular care when the
indicator light flashes.
■When the TRAC/VSC/Trailer
Sway Control systems are
turned off
●Be especially careful and drive
at a speed appropriate to the
road conditions. As these are
the systems to help ensure
vehicle stability and driving
force, do not turn the
TRAC/VSC/Trailer Sway Con-
trol systems off unless neces-
sary.
●Trailer Sway Control is part of
the VSC system and will not
operate if VSC is turned off or
experiences a malfunction.
■Dynamic Torque Vectoring
AWD system
The cornering performance of the
AWD system has been improved.
However, do not overly rely on the
system and drive with caution.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation pressure level.
The ABS, TRAC, Trailer Sway
Control and VSC systems will not
function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.

dealer immediately.
If the tire pressure warning light
comes on
1 After the temperature of the tires
has lowered sufficiently, check
the inflation pressure of each tire
and adjust them to the specified
level.
2 If the warning light does not turn
off even after several minutes
have elapsed, check that the
inflation pressure of each tire is
at the specified level and perform
initialization. ( P.426)
If the warning light does not turn off
several minutes after the initializa-
tion has been performed, have the
vehicle inspected by your Toyota
dealer immediately.
■The tire pressure warning light
may come on due to natural
causes
The tire pressure warning light may
come on due to natural causes such
as natural air leaks and tire inflation
pressure changes caused by tem- perature. In this case, adjusting the
tire inflation pressure will turn off the
warning light (afte
r a few minutes).
■When a tire is replaced with a
spare tire
Vehicles with a compact spare tire:
The compact spare tire is not
equipped with a tire pressure warn-
ing valve and transmitter. If a tire
goes flat, the tire pressure warning

ing light will turn on if the tire infla-
tion pressure of the spare tire is low.
If a tire goes flat, the tire pressure
warning light will not turn off even
though the flat tire has been
replaced with the spare tire.
Replace the spare tire with the
repaired tire and adjust the tire infla-
tion pressure. The tire pressure
warning light will go off after a few
minutes.
