While the Acceleration Suppression
at Low Speed function is operating,
if any of the following are performed,
the low speed sudden acceleration
suppression function operation will
be cancelled:
• The accelerator pedal is released
• The steering wheel is operated heavily or suddenly
■Detection of detectable objects
Objects are detected based on their
size, shape, and move-
ment.Depending on the ambient
brightness, movement, posture and
direction of a det ectable object, it
may not be detected and the system
may not operate properly.
The system detects shapes, such as
the following, as de tectable objects.
■Situations in which the system
may operate even though the
possibility of a collision is not
high
●In certain situations, such as the
following, the sys tem may deter-
mine that the possibility of a colli-
sion is high and operate:
• When passing a detectable object
• When changing lanes while over- taking a detectable object
• When suddenly approaching a detectable object
• When approaching a detectable
object or other object on the road- side, such as guardrails, utility
poles, trees, walls, etc.
• When there is a d etectable object
or other object by the roadside at
the entrance of a curve
• When there are patterns or a painting ahead of the vehicle that
may be mistaken for a detectable
object
• When passing a detectable object that is changing lanes or turning
left/right
• When passing a detectable object which is stopped to make a
left/right turn
• When a detectab le object stops

WARNING
●When driving over bumps in the
road
●When driving over roads with
potholes or uneven surfaces
■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/ABS/VSC is
activated
The slip indicator light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particula r 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.

Driving
Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
Have a service technician
inspect the condition of the
12-volt battery.
Have the vehicle fitted with
four snow tires.
Ensure that all tires are the same
size and brand.
Perform the following according
to the driving conditions:
Do not try to forcibly open a
window or move a wiper that
is frozen. Pour warm water
over the frozen area to melt
the ice. Wipe away the water
immediately to prevent it from
freezing.
To ensure proper operation of
the climate control system
fan, remove any snow that
has accumulated on the air
inlet vents in front of the wind-
shield.

Winter driving tips
Carry out the necessary
preparations and inspec-
tions before driving the
vehicle in winter. Always
drive the vehicle in a man-
ner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions
to reduce the risk of accidents.
Failure to do so m ay result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the size specified.
●Maintain the recommended
level of air pressure.
●Do not drive in excess of 75
mph (120 km/h), regardless of
the type of snow tires being
used.
●Use snow tires on all, not just
some wheels.
NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains
may damage the vehicle body
and suspension, and adversely
affect driving performance.
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and
attachment of snow tires affects
the operation of the tire pressure
warning valves and transmitters.
Before driving the vehicle

Maintenance and care
etc., molded into the sidewall of
each tire.
Replace the tires if the treadwear
indicators are showing on a tire.
■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are
showing on a tire
●You have tire damage such as
cuts, splits, cracks deep enough
to expose the fabric, and bulges
indicating internal damage
●A tire goes flat r epeatedly or can-
not be properly repaired due to the
size or location of a cut or other
damage
If you are not sure, consult with your
Toyota dealer.
■Tire life
Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used or damage i s not obvious.
■Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2
of the Gross Axle Weight Ratings
(GAWR) of either the front axle or
the rear axle, whichever is greater.
For the GAWR, see the Certification
Label.
For the maximum load of the tire,
see the load limit at maximum cold
tire inflation press ure mentioned on
the sidewall of the tire. ( P.453)
■Tire types
●Summer tires Summer tires are high-speed perfor-
mance tires best suited to highway
driving under dry conditions. Since
summer tires do not have the same
traction performance as snow tires,
summer tires are inadequate for
driving on snow-covered or icy
roads. For driving on snow-covered
roads or icy roads, the use of snow
tires is recommended. When install-
ing snow tires, be sure to replace all
four tires.
●All season tires
All season tires are designed to pro-
vide better traction in snow and to
be adequate for driving in most win-
ter conditions as well as for use
year-round. All se ason tires, how-
ever, do not have adequate traction
performance compared with snow
tires in heavy or loose snow. Also,
all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.
●Snow tires
For driving on snow-covered roads
or icy roads, we recommend using
snow tires. If you need snow tires,
select tires of the same size, con-
struction and load capacity as the
originally installed tires. Since your
vehicle has radial tires as original
equipment, make sure your snow
tires also have radi al construction.
Do not install studded tires without
first checking local regulations for
possible restrictions. Snow tires
should be installed on all wheels.
( P.291)
■If the tread on snow tires wears
down below 0.16 in. (4 mm)
The effectiveness of the tires as
snow tires is lost.
3606-3. Do-it-yourself maintenance
■Checking the tire valves
When replacing the tires, check the
tire valves for deformation, cracks,
and other damage.
Rotate the tires in the order
shown.
Front
To equalize tire w ear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
WARNING
■When inspecting or replacing
tires
Observe the following precautions
to prevent accidents.
Failure to do so may cause dam-
age to parts of t he drive train as
well as dangerous handling char-
acteristics, which may lead to an
accident resulting in death or seri-
ous injury.
●Do not mix tires of different
makes, models or tread pat-
terns.
Also, do not mix tires of remark-
ably different treadwear.
●Do not use tire sizes other than
those recommended by Toyota.
●Do not mix differently con-
structed tires (radial, bias-belted
or bias-ply tires).
●Do not mix summer, all season
and snow tires.
●Do not use tires that have been
used on another vehicle.
Do not use tires if you do not
know how they were used previ-
ously.
NOTICE
■If tire inflation pressure of
each tire becomes low while
driving
Do not continue driving, or your
tires and/or wheels may be
ruined.
■Driving on rough roads
Take particular care when driving
on roads with loose surfaces or
potholes.
These conditions may cause
losses in tire inflation pressure,
reducing the cushioning ability of
the tires. In addition, driving on
rough roads may cause damage
to the tires themselves, as well as
the vehicle’s wheels and body.

■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks. Make sure to
check tire inflation pressure as part
of your routine of daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the power switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after inflation pressure
has been adjusted.
●Tire inflation pressure changes
with temperature.
The displayed values may also be
different from th e values mea-
sured using a tire pressure gauge.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are
used.
• A tire has been replaced with a tire that is not an OE (Original
Equipment) tire.
• A tire has been replaced with a
tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-support ed run-flat tire
is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the speci-
fied level.
• If wheel withou t tire pressure
warning valves and transmitters
are used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure
warning computer.
●Performance may be affected in
the following situations.
• Near a TV tower, electric power plant, gas station, radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication
device
●If tire position information is not
correctly displayed due to the
radio wave conditions, the display
may be corrected by driving and
changing the radio wave condi-
tions.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
