2704-5. Using the driving support systems
WARNING
●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.

3046-1. 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.

NOTICE
■To prevent damage to the
vehicle when towing using a
wheel-lift type truck
●Vehicles without a smart key
system: Do not tow the vehicle
from the rear when the power
switch is off. The steering lock
mechanism is not strong
enough to hold the front wheels
straight.
●Vehicles with a smart key sys-
tem: Do not tow the vehicle from
the rear when th e power switch
is off.
●When raising the vehicle,
ensure adequate ground clear-
ance for towing at the opposite
end of the raised vehicle. With-
out adequate clearance, the
vehicle could be damaged while
being towed.
■To prevent damage to the
vehicle when towing with a
sling-type truck
Do not tow with a sling-type truck,
