Prius User-Guide (2010-2012)
Brake Assist
Preventing vehicle rollback when starting from a start on a hill is very
easy with a Prius. It offers a “brake assist” feature.
Press very hard on the brake pedal for about 2 seconds. That symbol to
the left will illuminate, informing you that the vehicle will remain in
place for a few seconds while you shift your foot from the brake to the
accelerator. When acceleration begins, the brake will automatically
release.
Tire Pressure
Low tire pressure is very dangerous, so much so that a federal mandate
was issued for all automakers to provide a warning to indicate when the
PSI has dropped 25 percent below the recommended minimum.
35 PSI front and 33 PSI rear is the recommended minimum by Toyota.
44 PSI front and 42 PSI rear is what owners wanting higher efficiency
and longer treadlife use.
