Driving
WARNING
●Moving the shift lever to N while
the vehicle is moving will disen-
gage the engine from the trans-
mission. Engine braking 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 positions 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 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.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other
than P or N, the vehicle may
accelerate suddenly and unex-
pectedly, causing an accident.
●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 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.

1264-1. Before driving
WARNING
●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 as a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift lever to P, stop the
engine and lock 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.
■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 t hat 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
Do not spin the wheels exces-
sively when a driven wheel 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.

may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
engine.
●Do not leave the vehicle with
the engine running for a long
time. If such a situation cannot
be avoided, park the vehicle in
an open space and ensure that
exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running
