■Detection area of the Parking Sup - port Brake function (rear-crossing
vehicles)
The detection area of the Parking Sup - port Brake function (rear-crossing vehi -
cles) differs from t he detection area of
the RCTA function ( →P.412). Therefore,
even if the RCTA function detects a
vehicle and provides an alert, the Park - ing Support Brake function (rear-cross -
ing vehicles) may not start operating.
■Conditions under which the Park -
ing Support Brake function (rear- crossing vehicles) will not detect a
vehicle
The Parking Support Brake function (rear-crossing vehicles) is not designed
to detect the following types of vehicles
and/or objects:
●Vehicles approaching from directly
behind
●Vehicles backing up in a parking
space next to your vehicle
●Vehicles that the sensors cannot
detect due to obstructions
●Vehicles which suddenly accelerate or
decelerate near your vehicle
●Guardrails, walls, signs, parked vehi -
cles and similar stationary objects*
●Small motorcycles, bicycles, pedestri -
ans, etc.*
●Vehicles moving away from your vehi - cle
●Vehicles approachin g from the park-
ing spaces next to your vehicle*
●Objects which are ex tremely close to
a radar sensor*
●Vehicles which are approaching from
the right or left at the rear of the vehi -
cle at a traveling sp eed of less than
approximately 8 km/h (5 mph)
●Vehicles which are approaching from
the right or left at the rear of the vehi - cle at a traveling sp eed of more than

4325-5. Using the driving support systems
approximately 24 km/h (15 mph)*: Depending on the conditions, detec-
tion of a vehicle and/or object may
occur.
■Situations in which the system may

damage.
A tire should only be repaired with
the emergency tire puncture repair
kit if the damage is caused by a nail
or screw passing through the tire
tread.
• Do not remove the nail or screw
from the tire. Removing the
object may widen the opening
and prevent emergency repair
with the repair kit.
• To avoid sealant leakage, move
the vehicle unt il the area of the
puncture, if known, is positioned
at the top of the tire.
If you have a flat tire
(vehicles without spare
tire)
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo -
rarily using the emergency tire
puncture repair kit. (The kit
contains a bottle of sealant.
The sealant can be used only
once to temporarily repair one
tire without removing the nail
or screw from the tire.)
Depending on the damage con -
dition of the flat tire, it may not
be able to repaired with the
emergency tire puncture repair
kit. ( →P.583)
After temporarily repairing the
tire with the kit , have the tire
repaired or replaced by any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
