Driving
■The system can be operated
when
●The power switch is in ON.
●The intuitive parking assist func-
tion is on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●The shift position is in a position
other than P.
■If “Parking Assist Unavailable
Sensor Blocked” is displayed
on the multi-information display
A sensor may be covered with ice,
snow, dirt, etc. Remove the ice,
snow, dirt, etc., from the sensor to
return the system to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal. If an abnormality is displayed even
though there are no water droplets,
ice, snow or dirt, the sensor may be
operating abnormally. Have the
vehicle inspected by your Toyota
dealer.
■If “System Stopped See
Owner’s Manual” is displayed
on the multi-information display
Water may be continuously flowing
over the sensor surf ace, such as in
a heavy rain. When the system
determines that it is normal, the sys-
tem will return to normal.
■If “System Malfunction Visit
Your Dealer” is displayed on
the multi-info rmation display
There may be a sensor or voltage
malfunction. Have the vehicle
inspected by your Toyota dealer.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’s front and rear bumpers.
●Certain vehicle conditions and the
surrounding environment may
affect the ability of a sensor to cor-
rectly detect an object.
●Objects may not be detected if
they are too close to the sensor.
●There will be a short delay
between object detection and dis-
play. Even at low speeds, there is
a possibility that the object will
come within the sensor’s detection
areas before the display is shown
and the warning beep sounds.
●It might be difficult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
●It may be difficult to hear the
buzzer if buzzers for other sys-
tems are sounding.
●If the meter malfunctions, the
buzzer may not sound.
WARNING
●Keep your tires properly
inflated.
●A non-genuine Toyota suspen-
sion (lowered suspension, etc.)
is installed.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area. Doing so ma y result in the
sensor malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.

4285-5. Using the driving support systems
WARNING
■When the TRAC/ABS/VSC is
activated
The slip indicator light flashes.
Always drive care fully. 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 pressure level.
The ABS, TRAC and VSC sys-
tems will not function correctly if
different tires are installed on the
vehicle.
Contact your Toyota dealer for
further 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 driv ing 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.

Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the specified size.
●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
(except 195/50R19 tires)
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 specified 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.

4305-6. Driving tips
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, outside rear
view mirrors, windows, vehi-
cle’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 position to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing 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 dangerous
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 position to P.
( P.264)
NOTICE
■Repairing or replacing snow
tires
