●Do not leave a door or window
open if the curved glass is coated
with a metallized film such as a sil- ver-colored one. Reflected sunlight
may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake,
shift the shift lever to P (vehicles
with an automatic transmission), stop the engine and lock the vehi-
cle.
Do not leave the vehicle unat- tended while the engine is running.
If the vehicle is parked with the shift
lever in P but the parking brake is not set, the vehicl e may start to
move, possibly leading to an acci-
dent.
●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 vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever
or depress the accelerator pedal, this
could cause an accident or fire due to engine overheating. Additionally, if the
vehicle is parked in a poorly ventilated
area, exhaust gases may collect and enter the vehicle, leading to death or
a serious health hazard.
■When braking
●When the brakes are 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 vehi-
cles closely and avoid hills or sharp
turns that require braking. In this case, braking is still possible,
but the brake pedal should be
depressed more firmly than usual. Also, the braking 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 indi-
vidual 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 excessively 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 propel the vehicle for-
ward or backward, causing an acci-
dent.
NOTICE
■Pre-driving check
Trapping small animals in the cooling
fan and belts of the engine may result
in a malfunction. Check that no small animal enters the engine compart-
ment and under the vehicle before
starting the engine.

1384-1. Before driving
WA R N I N G
●Do not place cargo or luggage in or
on the following locations as the
item may get under the clutch (manual transmission), brake or
accelerator pedal and prevent the
pedals from being depressed prop- erly, block the driver’s vision, or hit
the driver or passengers, causing
an accident:
• At the feet of the driver
• On the front passenger or rear
seats (when stacking items)
• On the package tray
• On the instrument panel
• On the dashboard
●Secure all items in the occupant
compartment, as they may shift and injure someone during sudden
braking, sudden swerving or an
accident.
■Load and distribution
●Do not overload your vehicle.
●Do not apply loads unevenly.
Improper loading may cause deteri- oration of steering or braking con-
trol which may cause death or
serious injury.
Trailer towing
Toyota does not recommend
towing a trailer with your vehi-
cle. Toyota also does not rec-
ommend the installation of a
tow hitch or the use of a tow
hitch carrier for a wheelchair,
scooter, bicycle, etc. Your vehi-
cle is not designed for trailer
towing or for the use of tow
hitch mounted carriers.

Before refueling the vehicle
WA R N I N G
■When refueling the vehicle
Observe the following precautions
while refueling the vehicle. Failure to
do so may result in death or serious injury.
●Do not handle fuel indoors.
●After exiting the vehicle and before
opening the fuel door, touch an unpainted metal surface to dis-
charge any static electricity. It is
important to discharge static elec- tricity before refueling because
sparks resulting from static electric-
ity can cause fuel vapors to ignite while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to
remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be
heard before fully removing the cap. In hot weather, pressurized
fuel may spray out the filler neck
and cause injury.
●Do not allow anyone that has not
discharged static electricity from their body to come close to an open
fuel tank.
●Do not allow anyone to approach
the area of the vehicle near the fuel
filler pipe while refueling is in pro- gress.
●Do not inhale vaporized fuel.Fuel contains substances that are
harmful if inhaled.
●Do not smoke while refueling the
vehicle.
Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is stati-
cally charged.
This may cause static electricity to build up, resulting in a possible igni-
tion hazard.
■When refueling
Observe the following precautions to
prevent fuel overflowing from the fuel tank:
●Securely insert the fuel nozzle into the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.
●Do not top off the fuel tank.

Doing so may damage the vehicle,
such as causing the emission con- trol system to ope rate abnormally
or damaging fuel system compo-
nents or the vehicle’s painted sur- face.
●Never add any cleaning agents to the fuel tank. The addition of a
cleaning agent may cause damage
to the fuel system.
●Immediately put fuel in the tank
whenever the low fuel warning light
illuminates. Engine misfires as a result of an empty tank could cause
damage to the engine.
