• The Parking Support Brake function (for
static objects) is on.
• The vehicle speed is 10 mph (15 km/h) or
less.
• There is an obstacle in the traveling direc-
tion of the vehicle (6 to 13 ft. [2 to 4 m]
ahead).
• The system determined that a stronger-
than-normal brake operation was neces-
sary to avoid a collision.
●
Brake control
• Hybrid system output restriction control
is being performed.
• The system determined that an emer-
gency brake operation was necessary to
avoid a collision.
■

ABS, brake assist, VSC, Trailer Sway
Control, TRAC and hill-start assist con-
trol systems
●
A sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the hybrid
system is started or just after the vehicle
begins to move. This sound does not indi-
cate that a malfunction has occurred in
any of these systems.
●
Any of the following conditions may
occur when the above systems are oper-
ating.
None of these indicates that a malfunc-
tion has occurred.
• Vibrations may be felt through the vehicle
body and steering.
• A motor sound may be heard also after
the vehicle comes to a stop.

The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering
input over an extended period of time. The
steering wheel may feel heavy as a result.
Should this occur, refrain from excessive
steering input or stop the vehicle and turn
the hybrid system off. The EPS system
should return to normal within 10 minutes.
