short
●Gratings and gutters
●When a sensor or the area around
a sensor is extremely hot or cold
●If the suspension has been modi-
fied or tires of a size other than
specified are installed
●If the front of the vehicle is raised
or lowered due to the carried load
*: If equipped
Safe Exit Assist*
The safe exit assist is a sys-
tem that uses rear side
radar sensors installed on
the inner side of the rear
bumper to help occupants
judge if an approaching
vehicle or bicycle may col-
lide with a door when open-
ing it or cancel opening of
the door, to reduce the pos-
sibility of a collision.
WARNING
■Cautions regarding the use of
the system
●The driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
●The safe exit assist is a supple-
mentary system that, when the
vehicle is stopped, informs
occupants of the existence of
approaching vehicles and bicy-
cles. As this system alone can-
not be used to judge safety,
over-reliance on this system
may lead to an accident result-
ing in death or serious injury.
In certain situations, this system
may not function to its fullest
extent. Therefore it is necessary
for the occupants to visually
check for safety directly and using
the mirrors.

2284-5. Using the driving support systems
●When the engine switch is turned
off
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when
vehicle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the engine
off. The EPS syst em should return
to normal within 10 minutes.
■Secondary Collision Brake
operating conditions
The system operates when the SRS
airbag sensor detects a collision
while the vehicle is in motion.
However, the system does not oper-
ate when the components are dam-
aged.
■Secondary Collision Brake
automatic cancellation
The system is automatically can-
celed in any of th e following situa-
tions.
●The vehicle speed drops below
approximately 0 mph (0 km/h)
●A certain amount of time elapses
during operation
●The accelerator pedal is
depressed a large amount
WARNING
■The ABS does not operate
effectively when
●The limits of tire gripping perfor-
mance have been exceeded
(such as excessively worn tires
on a snow covered road).
●The vehicle hydroplanes while
driving at high speed on wet or
slick roads.
■Stopping distance when the
ABS is operating may exceed
that of normal conditions
The ABS is not designed to
shorten the vehicle’s stopping dis-
tance. Always maintain a safe dis-
tance from the veh icle in front of
you, especially in the following sit-
uations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains
●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.

Driving
WARNING
■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.
■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.
■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.

Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician
inspect the condition of the
battery.
 Have the vehicle fitted with
four snow tires or purchase a
set of tire chains for the front
tires.

size and brand, and that chains
match the size of the tires.
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.
■Driving with tire chains
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in the
vehicle being unable to be driven
safely, and may cause death or
serious injury.
●Do not drive in excess of the
speed limit specifi ed for the tire
chains being used, or 30 mph
(50 km/h), whichever is lower.
●Avoid driving on bumpy road
surfaces or over potholes.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
●Slow down sufficiently before
entering a curve to ensure that
vehicle control is maintained.
●Do not use LTA (Lane Tracing
Assist) system.
●Do not use LDA (Lane Depar-
ture Alert) system.
NOTICE
■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.

2314-6. Driving tips

Driving
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.
 Check for and remove any
excess ice or snow that may
have accumulated on the
exterior lights, vehicle’s roof,
chassis, around the tires or on
the brakes.
 Remove any snow or mud
from the bottom of your shoes
before getting in the vehicle.
Accelerate the vehicle slowly,
keep a safe distance between
you and the vehicle ahead, and
drive at a reduced speed suit-
able to road conditions.
 Turn automatic mode of the
parking brake off. Otherwise, the parking brake may freeze
and not be able to be
released automatically.
Also, avoid using the following as
the parking brake may operate
automatically, even if automatic
mode is off.
• Brake hold system

Park the vehicle and shift the
shift lever to P without setting
the parking brake. The park-
ing brake may freeze up, pre-
venting it from being released.
If the vehicle is parked without
setting the parking brake,
make sure to block the
wheels.
Failure to do so may be dan-
gerous because it may cause
the vehicle to move unexpect-
edly, possibly leading to an
accident.
 When the parking brake is in
automatic mode, release the
parking brake after shifting
the shift lever to P. ( P.142)
 If the vehicle is parked without
setting the parking brake,
confirm that the shift lever
cannot be moved out of P.
 If the vehicle is left parked
with the brakes damp in cold
temperatures, there is a pos-
sibility of the brakes freezing.
Use the correct tire chain size
when mounting the tire chains.

WARNING
■When adding washer fluid
Do not add washer fluid when the
engine is hot or running as
washer fluid contains alcohol and
may catch fire if spilled on the
engine, etc.
NOTICE
■Do not use any fluid other
than washer fluid
Do not use soapy water or engine
antifreeze instead of washer fluid.
Doing so may cause streaking on
the vehicle’s painted surfaces, as
well as damaging the pump lead-
ing to problems of the washer
fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as
necessary.

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.
■Low profile tires (18-inch tires)
Generally, low prof ile tires will wear
more rapidly and t ire grip perfor-
mance will be reduced on snowy
and/or icy roads when compared to
standard tires. Be sure to use snow
tires or tire chains on snowy and/or
icy roads and drive carefully at a
speed appropriate for road and
weather conditions.
■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.375)
■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
