2021 TOYOTA HIGHLANDER HYBRID warning

3304-5. Using the driving support systems
HIGHLANDER HV_U
WARNING
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
■Trailer Sway Control precau-
tion
The Trailer Sway Control system
is not able to reduce trailer sway
in all situations . Depending on
many factors such as the condi-
tions of the vehicle, trailer, road
surface and driving environment,
the Trailer Sway Control system
may not be effec tive. Refer to
your trailer owner’s manual for
information on how to tow your
trailer properly.
■If trailer sway occurs
Observe the following precau-
tions.
Failing to do so may cause death
or serious injury.
●Firmly grip the steering wheel.
Steer straight ahead. Do not try
to control trailer sway by turning
the steering wheel.
●Begin releasing the accelerator
pedal immediately but very
gradually to reduce speed.
Do not increase speed. Do not
apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your
vehicle and trailer should stabi-
lize. (
P.202)
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.

Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
Have a service technician
inspect the condition of the
12-volt battery.
 Have the vehicle fitted with
four snow tires or purchase a
set of tire chains for the front
tires.
Ensure that all tires are the same
size and brand, and that chains
match the size of the tires.
Perform the following according
to the driving conditions:
Winter driving tips
Carry out the necessary
preparations and inspec-
tions before driving the
vehicle in winter. Always
drive the vehicle in a man-
ner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions
to reduce the risk of accidents.
Failure to do so m ay result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the specified size.
●Maintain the recommended
level of air pressure.
●Do not drive in excess of 75
mph (120 km/h), regardless of
the type of snow tires being
used.
●Use snow tires on all, not just
some wheels.
■Driving with tire chains
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in the
vehicle being unable to be driven
safely, and may cause death or
serious injury.
●Do not drive in excess of the
speed limit specifi ed for the tire
chains being used, or 30 mph
(50 km/h), whichever is lower.
●Avoid driving on bumpy road
surfaces or over potholes.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
●Slow down sufficiently before
entering a curve to ensure that
vehicle control is maintained.
●Do not use the LTA (Lane Trac-
ing Assist) system.
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and
attachment of snow tires affects
the operation of the tire pressure
warning valves and transmitters.

Always check local regulations
before installing chains.
■Tire chain installation
Observe the following precautions
when installing and removing
chains:
●Install and remove tire chains in a
safe location.
●Install tire chains on the front tires
only. Do not install tire chains on
the rear tires.
●Install tire chains on front tires as
tightly as possible. Retighten
chains after driving 1/4 1/2 mile
(0.5 1.0 km).
●Install tire chains following the
instructions provi ded with the tire
chains.

and transmitters may not function
correctly when tire chains are fit-
ted.

3364-6. Driving tips
HIGHLANDER HV_U
Specific design characteris-
tics give it a higher center of
gravity than ordinary passen-
ger cars. This vehicle design
feature causes this type of
vehicle to be more likely to
rollover. And, utility vehicles
have a significantly higher
rollover rate than other types
of vehicles.
 An advantage of the higher
ground clearance is a better
view of the road allowing you
to anticipate problems.
 It is not designed for corner-
ing at the same speeds as
ordinary passenger cars any
more than low-slung sports
cars are designed to perform
satisfactorily under off-road
conditions. Therefore, sharp
turns at excessive speeds
may cause the vehicle to roll-
over.
Utility vehicle precau-
tions
This vehicle belongs to the
utility vehicle class, which
has higher ground clear-
ance and narrower tread in
relation to the height of its
center of gravity.
Utility vehicle feature
WARNING
■Utility vehicle precautions
Always observe t he following pre-
cautions to minim ize the risk of
death, serious injury or damage to
your vehicle:
●In a rollover crash, an unbelted
person is significantly more
likely to die than a person wear-
ing a seat belt. Therefore, the
driver and all passengers
should always fasten their seat
belts.
●Avoid sharp turns or abrupt
maneuvers, if at all possible.
Failure to operat e this vehicle
correctly may result in loss of
control or vehicle rollover caus-
ing death or serious injury.
●Loading cargo on the roof lug-
gage carrier (if equipped) will
make the center of the vehicle
gravity higher. Avoid high
speeds, sudden starts, sharp
turns, sudden braking or abrupt
maneuvers, otherwise it may
result in loss of control or vehi-
cle rollover du e to failure to
operate this vehicle correctly.
●Always slow down in gusty
crosswinds. Because of its pro-
file and higher ce nter of gravity,
your vehicle is more sensitive to
side winds than an ordinary
passenger car. Slowing down
will allow you to have better
control.
●Do not drive horizontally across
steep slopes. Driving straight up
or straight down is preferred.
Your vehicle (or any similar
off-road vehicle) can tip over
sideways much more easily
than forward or backward.

Driving
HIGHLANDER HV_U
Your vehicle is not designed to
be driven off-road. However, in
the event that off-road driving
cannot be avoided, please
observe the following precau-
tions to help avoid the areas
prohibited to vehicles.
Drive your vehicle only in
areas where off-road vehicles
are permitted to travel.
 Respect private property. Get
owner’s permission before
entering private property.
 Do not enter areas that are
closed. Honor gates, barriers
and signs that restrict travel.
 Stay on established roads.
When conditions are wet,
driving techniques should be
changed or travel delayed to
prevent damage to roads.
■Additional information for
off-road driving
For owners in U.S. mainland,
Hawaii and Puerto Rico:
To obtain additional information per-
taining to driving your vehicle
off-road, consult the following orga-
nizations.
●State and Local Parks and Recre-
ation Departments
●State Motor Vehicle Bureau
●Recreational Vehicle Clubs
●U.S. Forest Service and Bureau of
Land Management
Off-road drivingWARNING
■Off-road driving precautions
Always observe t he following pre-
cautions to minim ize the risk of
death, serious injury or damage to
your vehicle:
●Drive carefully when off the
road. Do not take unnecessary
risks by driving in dangerous
places.
●Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel
and injure your hands. Keep
both hands and especially your
thumbs on the ou tside of the
rim.
●Always check your brakes for
effectiveness immediately after
driving in sand, mud, water or
snow.
●After driving through tall grass,
mud, rock, sand, rivers, etc.,
check that there is no grass,
bush, paper, rags, stone, sand,
etc. adhering or trapped on the
underbody. Clear off any such
matter from the underbody. If
the vehicle is used with these
materials trapped or adhering to
the underbody, a breakdown or
fire could occur.
●When driving off-road or in rug-
ged terrain, do not drive at
excessive speeds, jump, make
sharp turns, strike objects, etc.
This may cause loss of control
or vehicle rollover causing
death or serious injury. You are
also risking expensive damage
to your vehicle’s suspension
and chassis.
