391-1. For safe use

For safety and security
WARNING
●Do not use seat accessories
which cover the parts where the
SRS side airbags and SRS seat
cushion airbag inflate as they
may interfere with inflation of
the SRS airbags. Such acces-
sories may prevent the side air-
bags and seat cushion airbag
from activating correctly, disable
the system or cause the side
airbags and seat cushion airbag
to inflate accidentally, resulting
in death or serious injury.
●Do not strike or apply significant
levels of force to the area of the
SRS airbag components or the
front doors.
Doing so can cause the SRS
airbags to malfunction.
●Do not touch any of the compo-
nent parts immediately after the
SRS airbags have deployed
(inflated) as they may be hot.
●If breathing becomes difficult
after the SRS airbags have
deployed, open a door or win-
dow to allow fresh air in, or
leave the vehicle if it is safe to
do so. Wash off any residue as
soon as possible to prevent skin
irritation.
●If the areas where the SRS air-
bags are stored, such as the
steering wheel pad and front
and rear pillar ga rnishes, are
damaged or cracked, have
them replaced by your Toyota
dealer.
●Do not place anything, such as
a cushion, on the front passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the SRS front airbags for
the front passenger may not
deploy in the event of a colli-
sion.
■Modification and disposal of
SRS airbag system compo-
nents
Do not dispose of your vehicle or
perform any of the following modi-
fications without consulting your
Toyota dealer. The SRS airbags
may malfunction or deploy
(inflate) accidentally, causing
death or serious injury.
●Installation, re moval, disassem-
bly and repair of the SRS air-
bags
●Repairs, modific ations, removal
or replacement of the steering
wheel, instrument panel, dash-
board, seats or seat upholstery,
front, side and rear pillars, roof
side rails, front door panels,
front door trims or front door
speakers
●Modifications to the front door
panel (such as making a hole in
it)
●Repairs or modifications of the
front fender, front bumper, or
side of the occupant compart-
ment
●Installation of a grille guard (bull
bars, kangaroo bar, etc.), snow
plows, winches or roof luggage
carrier
●Modifications to the vehicle’s
suspension system

Driving
When the following unusual
operation is performed with the
accelerator pedal depressed,
the engine output may be
restrained.
When the shift lever is shifted
to R
*.
 When the shift lever is shifted
from P or R to forward drive
shift position such as D
*.
When the system op erates, a mes-
sage appears on the multi-informa-
tion display. Read the message and
follow the instruction.
*: Depending on the situation, the shift position may not be
changed.
■Drive-Start Control (DSC)
When the TRAC is turned off
(  P.250), sudden start restraint
control also does not operate. If
your vehicle have trouble escaping
from the mud or fresh snow due to
sudden start restraint control opera-
tion, deactivate TRAC ( P.250) so
that the vehicle may become able to
escape from the mud or fresh snow.
Cargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) — (Total weight of
occupants)
Steps for Determining Correct
Load Limit —
(1) Locate the statement “The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined
weight of the driver and passen-
gers that will be riding in your
vehicle.
(3) Subtract the combined
weight of the driver and passen-
gers from XXX kg or XXX lbs.
(4) The resulting figure equals
the available amount of cargo
and luggage load capacity.
For example, if the “XXX”
amount equals 1400 lbs. and
there will be five 150 lb passen-
gers in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs. (1400 −

WARNING
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Active Cornering Assist does
not operate effectively when
●Do not overly rely on Active
Cornering Assist. Active Corner-
ing Assist may not operate
effectively when accelerating
down slopes or driving on slip-
pery road surfaces.
●When Active Cornering Assist
frequently operates, Active Cor-
nering Assist may temporarily
stop operating to ensure proper
operation of the brakes, TRAC
and VSC.
■Hill-start assist control does
not operate effectively when
●Do not overly rely on hill-start
assist control. Hill-start assist
control may not operate effec-
tively on steep inclines and
roads covered with ice.
●Unlike the parking brake,
hill-start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.
■When the TRAC/VSC is acti-
vated
The slip indicator light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particular care when the
indicator light flashes.
■When the TRAC/VSC systems
are turned off
Be especially careful and drive at
a speed appropriate to the road
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn
the TRAC/VSC systems off
unless necessary.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation p ressure level.
The ABS, TRAC and VSC sys-
tems will not functi on correctly if
different tires are installed on the
vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.

2906-1. Maintenance and care
NOTICE
■To prevent damage to the
windshield wiper arms
When lifting the wiper arms away
from the windshield, pull the driver
side wiper arm upward first, and
repeat for the passenger side.
When returning the wipers to their
original position, do so from the
passenger side first.
■When using a high pressure
car wash
●When washing the vehicle, do
not spray the came ra or its sur-
rounding area directly with a
high pressure washer. Shock
applied from high pressure
water may cause the device to
not operate normally.
●Do not spray water directly on
the radar which is equipped
behind the emblem. Otherwise
it may cause the device to be
damaged.
●Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicle body. Otherwise
resin section, such as moldings
and bumpers, may be deformed
and damaged. Also, do not con-
tinuously hold the nozzle in the
same place.
●Do not spray the lower part of
the windshield continuously. If
water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.
●Do not wash the underside of
the vehicle using a high pres-
sure car washer.

trunk. ( P.371)
 Fluid leaks under the vehicle.
(Water dripping from the air
conditioning after use is nor-
mal.)
