Before driving
WARNING
●Check to make sure that all pas-
sengers do not have any part of
their body in a position where it
could be caught when the pan-
oramic moon roof is being oper-
ated.
●When exiting the vehicle, turn
the engine switch off, carry the
key and exit the vehicle along
with the child. There may be
accidental operation, due to
mischief, etc., that may possibly
lead to an accident.
■Jam protection function
●Never use any part of your body
to intentionally activate the jam
protection function.
●The jam protection function may
not work if something gets
caught just before the pan-
oramic moon roof or electronic
sunshade is fully closed. Also,
the jam protecti on function is
not designed to operate while
the switch is being pressed.
Take care so that your fingers,
etc. do not get caught.
■To prevent burns or injuries
Do not touch the area between
the underside of the panoramic
moon roof and the electronic sun-
shade. Your hand may get caught
and you could injure yourself.
Also, if the vehicle is left in direct
sunlight for a long time, the under-
side of the panoramic moon roof
could become very hot and could
cause burns.
NOTICE
■To prevent damage to the
panoramic moon roof
●Before opening the panoramic
moon roof, make sure that there
are no foreign objects, such as
stones or ice, around the open-
ing.
●Do not hit the surface or edge of
the panoramic moon roof with
hard objects.

WARNING
Observe the following precau-
tions.
Failure to do so m ay 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 i f 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.How-
ever, in the event of an emer-
gency, such as if it becomes
impossible to stop the vehicle in
the normal way:
P.424
●Use engine braking (downshift)
to maintain a safe speed when
driving down a steep hill.Using
the brakes continuously may
cause the brakes to overheat
and lose effectiveness.
(
P.201)
●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. Drive with due
care if it becomes unavoidable
to drive off-road.

Driving
WARNING
●Do not drive across a river or
through other bodies of
water.This may cause elec-
tric/electronic components to
short circuit, damage the engine
or cause other serious damage
to the vehicle.
●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 perfor-
mance, resulting in an accident
or damage to the vehicle.
●Do not shift the sh ift lever to P
while the vehicle is mov-
ing.Doing so can damage the
transmission 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
transmission 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 transmission
and may result in a loss of vehi-
cle 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.

1784-1. Before driving
WARNING
■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 th e 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.
■When the vehicle is stopped
●Do not race the engine.If the
shift lever is in any position
other than P or N, the vehicle
may accelerate suddenly and
unexpectedly, causing an acci-
dent.
●In order to prev ent 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 following:
• 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.

Gross trailer weight
Tongue weight
If using a weight distributing hitch
when towing, return the front axle to
the same weight as before the
trailer connection.
If front axle weight cannot be mea-
sured directly, measure the front
fender height above the front axle
before connection. Adjust weight
distributing hitch torque until front
fender is returned to the same
height as before connection.
The gross trailer weight, gross axle
weight and tongue weight can be
measured with platform scales
found at a highway weighing sta-
tion, building supply company,
trucking company, junk yard, etc.
Trailer hitch assemblies have
different weight capacities. Toy-
ota recommends the use of Toy-
ota hitch/bracket for your
vehicle. For details, contact your
Toyota dealer.
 If you wish to install a trailer
hitch, contact your Toyota
dealer.
 Use only a hitch that con- forms to the gross trailer
weight requirement of your
vehicle.
 Follow the directions supplied
by the hitch manufacturer.
 Lubricate the hitch ball with a
light coating of grease.
 Remove the hitch ball when-
ever you are not towing a
trailer. Remove the trailer
hitch if you do not need it.
After removing the hitch, seal
any mounting hole in the vehi-
cle body to prevent entry of
any substances into the vehi-
cle.
Hitch
WARNING
■Hitch
Trailer hitch assemblies have dif-
ferent weight capacities estab-
lished by the hitch manufacturer.
Even though the vehicle may be
physically capable of towing a
higher weight, the operator must
determine the maximum weight
rating of the particular hitch
assembly and never exceed the
maximum weight rating specified
for the trailer-hitch. Exceeding the
maximum weight rating set by the
trailer-hitch manufacturer can
cause an accident resulting in
death or serious personal injuries.
NOTICE
■When installing a trailer hitch
Use only the position recom-
mended by your Toyota dealer.
