■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
operate even though there is no possibility of a collision
In some situations such as the following,
the Parking Support Brake function (rear-crossing vehicles) may operate
even though there is n o possibility of a
collision.
●When the parking space faces a
street and vehicles are being driven on the street
●When a detected vehicle turns while approaching the vehicle
●When a vehicle passe s by the side of your vehicle
●When the distance between your vehi -
cle and metal objects, such as a guardrail, wall, sign, or parked vehicle,
which may reflect electrical waves
toward the rear of the vehicle, is short
●When there are spinning objects near
your vehicle such as the fan of an air conditioning unit
●When water is spla shed or sprayed toward the rear bumper, such as from
a sprinkler
■Situations in which the Parking

■If “Exhaust Filter Full See Owner’s
Manual” is shown on the multi-
information display
●The message may be displayed while
high load driving with particulate mat - ter accumulating.
●Hybrid system output (engine speed) is restricted when a certain amount of
particulate matter accumulates, how-
ever, it is possible to drive the vehicle unless the malfuncti on indicator lamp
comes on.
●Particulate matter can accumulate
more quickly if t he vehicle is fre-
quently driven short trips or at low speeds, or if the h ybrid system is reg-
ularly started in an extremely cold
environment. Excessive accumula -
tion of particulate matter can be pre - vented by periodically driving long
distances continu ously with intermit-
tent releasing of the accelerator pedal, such as when dri ving on highways
and freeways.
■If the malfunction indicator lamp
comes on or “Hybrid System Mal - function Output Power Reduced
Visit Your Dealer” is shown on the
multi-information display
The amount of accumulated particulate
matter has exceeded a certain level.
Have the vehicle i nspected by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer immediately.
GPF (Gasoline Particu-
late Filter) system
The GPF system collects par -
ticulate matter in the exhaust
gas by using an exhaust gas
filter. The system will operate
to regenerate the filter auto -
matically, depending on the
vehicle conditions.
NOTICE
■To prevent the GPF system from
not operating properly
●Do not use fuel other than the spec - ified type
●Do not modify the exhaust pipes
