Driving
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 you 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 response 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.442
●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.204)
●Do not adjust the positions of
the steering wheel, the seat, or
the inside or outside rear view
mirrors while driving.
Doing so may resu lt 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.

1804-1. 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 mph (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 shift 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 shift 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 available 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.

NOTICE
●When driving over bumps on
the road, drive as slowly as pos-
sible to avoid damaging the
wheels, underside of the vehi-
cle, etc.
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations. Hold the
steering wheel firmly and gradu-
ally depress the brake pedal to
slow down the vehicle.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.
Information on what to do in case
of a flat tire (
P.464)
■When encountering flooded
roads
Do not drive on a road that has
flooded after heavy rain etc.
Doing so may cause the following
serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by
water immersion
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Toy-
ota dealer check the following:
●Brake function
●Changes in quantity and quality
of oil and fluid used for the
engine, transaxle, transfer
(AWD models), rear differential
(AWD models), etc.
●Lubricant condition for the pro-
peller shaft (AWD models),
bearings and suspension joints
(where possible), and the func-
tion of all joints, bearings, etc.

Driving
●All trailer lights work as required
by law.
●All lights work each time you con-
nect them.
●The trailer ball is set at the proper
height for the coupler on the
trailer.
●The trailer is level when it is
hitched.
Do not drive if the trailer is not
level, and check for improper
tongue weight, overloading, worn
suspension, or other possible
causes.
●The trailer cargo is securely
loaded.
●The rear view mirrors conform to
all applicable federal, state/provin-
cial or local regulations. If they do
not, install rear view mirrors
appropriate for towing purposes.
■Break-in schedule
If your vehicle is new or equipped
with any new power train compo-
nents (such as an engine, transaxle,
transfer [AWD models], rear differ-
ential [AWD models] or wheel bear-
ing), Toyota recommends that you
do not tow a trailer until the vehicle
has been driven for over 500 miles
(800 km).
After the vehicle has been driven for
over 500 miles (800 km), you can
start towing. However, for the next
500 miles (800 km), drive the vehi-
cle at a speed of less than 50 mph
(80 km/h) when towing a trailer, and
avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle
will require more fr equent mainte-
nance due to the additional load.
(See “Scheduled Maintenance
Guide” or “Owner’s Manual Sup-
plement”.)
●Retighten the fixing bolts of the
towing ball and bracket after
approximately 600 miles (1000
km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds,
passing vehicles, rough roads, etc.)
can adversely affect handling of
your vehicle and trailer, causing
instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway-
ing by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradu-
ally 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 stabilize.
(if enabled, Trailer Sway Control can
also help to stabilize the vehicle and
trailer.)
●After the trailer swaying has
stopped:
• Stop in a safe pl ace. Get all occu-
pants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not
shifted.
Make sure the tongue weight is
appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not over-
loaded after occupants get in.
If you cannot find any problems, the
speed at which trailer swaying
occurred is beyond the limit of your
particular vehicle-trailer combina-
tion. Drive at a lower speed to pre-
vent instability. Remember that
swaying of the towing vehicle-trailer
increases as speed increases.
