Driving
WARNING
■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 caus e 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 seat 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 as a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift lever to P (vehicles
with an automatic transmission),
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 depress 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 are wet, drive
more cautiously.
Braking distance increases
when the brakes are wet, and
this may cause one side of the
vehicle to brake d ifferently than
the other side. Also, the parking
brake may not securely hold the
vehicle.

WARNING
■Things that must not be car-
ried in the trunk
The following things may cause a
fire if loaded in the trunk:
●Receptacles co ntaining gaso-
line
●Aerosol cans
■Storage precautions
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
●Stow cargo and luggage in the
trunk whenever possible.
●To prevent cargo and luggage
from sliding forward during
braking, do not stack anything in
the enlarged trunk. Keep cargo
and luggage low, as close to the
floor as possible.
●When you fold down the rear
seats, long items should not be
placed directly behind the front
seats.
●Never allow anyone to ride in
the enlarged trunk. It is not
designed for passengers. They
should ride in their seats with
their seat belts properly fas-
tened. Otherwise, they are
much more likely to suffer death
or serious bodily injury, in the
event of sudden braking, sud-
den swerving or an accident.
●Do not place cargo or luggage
in or on the follo wing locations
as the item may get under the
clutch (manual transmission),
brake or accelerator pedal and
prevent the pedals from being
depressed properly, block the
driver’s vision, or hit the driver
or passengers, causing an acci-
dent:
• 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 sud-
den braking, sudden swerving
or an accident.
■Capacity and distribution
●Do not exceed the maximum
axle weight rating or the total
vehicle weight rating.
●Even if the total load of occu-
pant’s weight and the cargo
load is less than the total load
capacity, do not apply the load
unevenly. Improper loading may
cause deterioration of steering
or braking control which may
cause death or serious injury.

Doing so may damage the vehi-
cle, such as causing the emis-
sion control system to operate
abnormally or damaging fuel
system components or the vehi-
cle’s painted surface.
●Never add any cleaning agents
to the fuel tank. The addition of
a cleaning agent may cause
damage to the fuel system.

3106-3. Do-it-yourself maintenance
■Checking battery fluid
Check that the level is between
the “UPPER LEVEL” and
“LOWER LEVEL” lines.
“UPPER LEVEL” line
“LOWER LEVEL” line
If the fluid level is at or below the
“LOWER LEVEL” line, add distilled
water.
■Adding distilled water
1 Remove the vent plug.
2 Add distilled water.
If the “UPPER LEVEL ” line cannot
be seen, check the fluid level by
looking directly at the cell.
3 Put the vent plug back on
and close it securely.
■Before recharging
When recharging, t he battery pro-
duces hydrogen ga s which is flam-
mable and explosive. Therefore, observe the following before
recharging:
●If recharging with the battery
installed on the vehicle, be sure to
disconnect the ground cable.
●Make sure the power switch on
the charger is off when connecting
and disconnecting the charger
cables to the battery.
■After recharging/reconnecting
the battery
The engine may not start. Follow the
procedure below to initialize the sys-
tem.
1 Shift the shift lever to P (auto-
matic transmission) or depress
the brake pedal with the shift
lever in N (manual transmission).
2 Open and close either door.
3 Restart the engine.
●Unlocking the doors using the
smart key system may not be pos-
sible immediately after reconnect-
ing the battery. If this happens,
use the wireless remote control or
the mechanical key to lock/unlock
the doors.
●Start the engine with the engine
switch in ACC. T he engine may
not start with th e engine switch
turned off. However, the engine
will operate normally from the sec-
ond attempt.
●The engine switch mode is
recorded by the vehicle. If the bat-
tery is disconnected and recon-
nected, the vehi cle will return the
engine switch mode to the status it
was in before the battery was dis-
connected. Make sure to turn off
the engine before disconnecting
the battery. Take extra care when
connecting the battery if the
engine switch mode prior to the
battery being disconnected is
unknown.
If the system will not start even after
multiple attempts, contact your Toy-
ota dealer.
