WARNING
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
■When starting the vehicle
Always keep your foot on the
brake pedal while stopped with
the engine running. This prevents
the vehicle from creeping.
■When driving the vehicle
●Do not drive if y ou are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to a
difficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the
brake pedal using your left foot
may delay respon se in an emer-
gency, resulting in an accident.
●Do not drive the vehicle over or
stop the vehicle near flammable
materials.
The exhaust system and
exhaust gases can be
extremely hot. These hot parts
may cause a fire if there is any
flammable material nearby.
●During normal driving, do not
turn off the engine. Turning the
engine off while driving will not
cause loss of steering or brak-
ing control, but the power assist
to these systems will be lost.
This will make it more difficult to
steer and brake, so you should
pull over and stop the vehicle as
soon as it is safe to do so.
However, in the event of an
emergency, such as if it
becomes impossible to stop the
vehicle in the normal way:
P.450
●Use engine braking (downshift)
to maintain a safe speed when
driving down a steep hill.
Using the brakes continuously
may cause the brakes to over-
heat and lose effectiveness.
(
P.206)
●Do not adjust the positions of
the steering wheel, the seat, or
the inside or outside rear view
mirrors while driving.
Doing so may result in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, heads or other parts
of their body are not outside the
vehicle.
●AWD models: This is not an
AWD vehicle designed for
off-road driving. Proceed with all
due caution if it becomes
unavoidable to drive off-road.
●Do not drive across a river or
through other bodies of water.
This may cause electric/elec-
tronic components to short cir-
cuit, damage the engine or
cause other serious damage to
the vehicle.

1824-1. Before driving
HIGHLANDER_U
WARNING
●Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 85 mph (140 km/h)
unless your vehicle has
high-speed capability tires. Driv-
ing over 85 mp h (140 km/h)
may result in tire failure, loss of
control and possible injury. Be
sure to consult a tire dealer to
determine whether the tires on
your vehicle are high-speed
capability tires or not before
driving at such speeds.
■When driving on slippery
road surfaces
●Sudden braking, acceleration
and steering may cause tire
slippage and reduce your ability
to control the vehicle.
●Sudden acceleration, engine
braking due to shifting, or
changes in engine speed could
cause the vehicle to skid.
●After driving through a puddle,
lightly depress the brake pedal
to make sure that the brakes
are functioning properly. Wet
brake pads may prevent the
brakes from functioning prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.
■When shifting the shift lever
●Do not let the vehicle roll back-
ward while the shift lever is in a
driving position, or roll forward
while the shift lever is in R.
Doing so may cause the engine
to stall or lead to poor brake and
steering performance, resulting
in an accident or damage to the
vehicle.
●Do not shift the sh ift lever to P
while the vehicle is moving.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the sh ift lever to R
while the vehicle is moving for-
ward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to a
driving position while the vehicle
is moving backward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Shifting the shift lever to N while
the vehicle is moving will disen-
gage the engine. Engine brak-
ing is not availa ble when N is
selected.
●Be careful not to shift the shift
lever with the accelerator pedal
depressed. Shifting the shift
lever to any position other than
P or N may lead to unexpected
rapid acceleration of the vehicle
that may cause an accident and
result in death or serious injury.
■If you hear a squealing or
scraping noise (brake pad
wear limit indicators)
Have the brake pads checked and
replaced by your Toyota dealer as
soon as possible.
Rotor damage may result if the
pads are not replaced when
needed.
It is dangerous to drive the vehicle
when the wear limits of the brake
pads and/or those of the brake
discs are exceeded.

WARNING
■When the vehicle is stopped
●Do not race the engine.
If the shift lever is in any posi-
tion other than P or N, the vehi-
cle may accelerate suddenly
and unexpectedly, causing an
accident.
●In order to prevent accidents
due to the vehicle rolling away,
always keep depressing the
brake pedal while the engine is
running, and apply the parking
brake as necessary.
●If the vehicle is stopped on an
incline, in order to prevent acci-
dents caused by the vehicle roll-
ing forward or backward, always
depress the brake pedal and
securely apply the parking
brake as needed.
●Avoid revving or racing the
engine.
Running the engine at high
speed while the vehicle is
stopped may cause the exhaust
system to overheat, which could
result in a fire if combustible
material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray cans, or soft
drink cans in the vehicle when it
is in the sun.
Doing so may result in the fol-
lowing:
• Gas may leak from a cigarette lighter or spray can, and may
lead to a fire.
• The temperature inside the vehicle may cause the plastic
lenses and plastic material of
glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray
over the interior of the vehicle,
and may also cause a short cir-
cuit in the vehicle’s electrical
components.
●Do not leave cigarette lighters in
the vehicle. If a cigarette lighter
is in a place such as the glove
box or on the floor, it may be lit
accidentally when luggage is
loaded or the se at is adjusted,
causing a fire.
●Do not attach adhesive discs to
the windshield or windows. Do
not place containers such as air
fresheners on the instrument
panel or dashboard. Adhesive
discs or containers may act as
lenses, causing a fire in the
vehicle.
●Do not leave a door or window
open if the curved glass is
coated with a metallized film
such as a silver-colored one.
Reflected sunlight may cause
the glass to act a s a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift lever to P, stop the
engine and loc k the vehicle.
Do not leave the vehicle unat-
tended while the engine is run-
ning.
If the vehicle is parked with the
shift lever in P but the parking
brake is not set, the vehicle may
start to move, possibly leading
to an accident.
●Do not touch the exhaust pipes
while the engine is running or
immediately after turning the
engine off.
Doing so may cause burns.

1844-1. Before driving
HIGHLANDER_U
WARNING
■When taking a nap in the vehi-
cle
Always turn the engine off. Other-
wise, if you accidentally move the
shift lever or dep ress the acceler-
ator pedal, this could cause an
accident or fire due to engine
overheating. Additionally, if the
vehicle is parked in a poorly venti-
lated area, exhaust gases may
collect and enter the vehicle, lead-
ing to death or a serious health
hazard.
■When braking
●When the brakes a re wet, drive
more cautiously.
Braking distance increases
when the brakes are wet, and
this may cause one side of the
vehicle to brake differently than
the other side. Also, the parking
brake may not securely hold the
vehicle.
●If the brake booster device does
not operate, do not follow other
vehicles closely and avoid hills
or sharp turns that require brak-
ing.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing distance will increase. Have
your brakes fixed immediately.
●Do not pump the brake pedal if
the engine stalls.
Each push on the brake pedal
uses up the reserve for the
power-assisted brakes.
●The brake system consists of 2
individual hydraulic systems; if
one of the systems fails, the
other will still operate. In this
case, the brake pedal should be
depressed more firmly than
usual and the braking distance
will increase. Have your brakes
fixed immediately.
■If the vehicle becomes stuck
(AWD models)
Do not spin the wheels exces-
sively when any of the tires is up
in the air, or the vehicle is stuck in
sand, mud, etc. This may damage
the driveline components or pro-
pel the vehicle forward or back-
ward, causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the engine output.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■When parking the vehicle
Always set the parking brake and
shift the shift lever to P. Failure to
do so may cause the vehicle to
move or the vehicle may acceler-
ate suddenly if t he accelerator
pedal is accidentally depressed.
■Avoiding damage to vehicle
parts
●Do not turn the steering wheel
fully in either direction and hold
it there for an extended period
of time.
Doing so may damage the
power steering motor.
