1343-2. Opening, closing and locking the doors
side the cabin and the door will
become lockable from the outside,
possibly trapping the electronic
key inside the vehicle.
●As long as the electronic key is
within the effective range, the
doors may be locked or unlocked
by anyone. However, only the
doors detecting the electronic key
can be used to unlock the vehicle.
●Even if the electronic key is not
inside the vehicle, it may be possi-
ble to start the engine if the elec-
tronic key is near the window.
●The doors may unlock or lock if a
large amount of water splashes on
the door handle, such as in the
rain or in a car wash when the
electronic key is w ithin the effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 seconds if the
doors are not opened and closed.)
●If the wireless remote control is
used to lock the doors when the
electronic key is near the vehicle,
there is a possib ility that the door
may not be unlocke d by the entry
function. (Use the wireless remote
control to unloc k the doors.)
●Touching the door lock or unlock
sensor while wearing gloves may
prevent lock or unlock operation.
●When the lock op eration is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recogniti on signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective ran ge, the door may
lock and unlock repeatedly. In that
case, follow the fo llowing correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca- tion 6 ft. (2 m) or more away from
the vehicle. (Take care to ensure
that the key is not stolen.)
• Set the electronic key to bat- tery-saving mode to disable the
smart key system. (
P.133)
●If the electronic key is inside the
vehicle and a door handle
becomes wet during a car wash, a

multi-information display and a
buzzer will sound outside the vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it comes into contact
with ice, snow, m ud, etc. Clean
the lock sensor and attempt to
operate it again, or use the lock
sensor on the lower part of the
door handle.
●A sudden handle operation or a
handle operation immediately
after entering the effective range
may prevent the doors from being
unlocked. Touch the door unlock
sensor and check that the doors
are unlocked befo re pulling the
door handle again.
●If there is another electronic key in
the detection area, it may take
slightly longer to unlock the doors
after the door handle is gripped.

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.

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.

1864-1. Before 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 regu lations. 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
●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 contr ol 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 place. 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.
