■The Parking Support Brake func- tion (static object) will operate
when
The function will operate when the PKSB OFF indicator is not illuminated or
flashing ( P.91, 92) and all of the fol- lowing conditions are met:
●Hybrid system output restriction con-trol• The Parking Support Brake is
enabled. • The vehicle speed is approximately 15 km/h (9 mph) or less.
• There is a static object in the traveling direction of the vehicle and approxi-mately 2 to 4 m (6 to 13 ft.) away.
• The Parking Support Brake deter- mines that a stronger-than-normal brake operation is necessary to avoid
a collision.
●Brake control
• Hybrid system output restriction con- trol is operating.• The Parking Support Brake deter-
mines that an immediate brake opera- tion is necessary to avoid a collision.
■The Parking Support Brake func-tion (static objects) will stop oper-
ating when
The function will stop operating if any of the following conditions are met:
●Hybrid system output restriction con-
trol • The Parking Support Brake is dis-abled.
• The system determines that the colli- sion has become avoidable with nor-mal brake operation.

Provides an optimal balance of fuel
economy, quietness, and dynamic per-
formance. Suitable for normal driving.
2 Power mode
Controls the hybrid system to provide
quick, powerful acceleration. Making it
suitable for when agile driving response
is desired, such as when driving on
roads with many curves.
When the Power mode is selected,
Power mode indicator comes on.
3 Eco drive mode
Helps the driver accelerate in an eco-
friendly manner and improve fuel econ-
omy through moderate throttle charac-
teristics and by controlling the operation
of the air conditioning system (heat-
ing/cooling).
When the Eco drive mode is selected,

■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 (engine speed) is restricted when a certain amount of
particulate matter accumulates, how- ever, it is possible to drive the vehicle unless the malfunction indicator lamp
comes on.
●Particulate matter can accumulate
more quickly if the vehicle is fre- quently driven short trips or at low speeds, or if the hybrid 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 continuously with intermit-tent releasing of the accelerator pedal,
such as when driving 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 inspected 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 f ilter automati-
cally, 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
