In some situations such as the following,
●
the system may detect a pedestrian and
display a warning on the head-up display,

• When driving on a horizontally slanted
road
• If the driver's posture (driver seat posi-
tion) is extreme, such as excessively
reclined

nates and a warning message is dis-
played on the multi-information display
The pre-collision system may be temporar-
ily unavailable or there may be a malfunc-

attached to the windshield near the cam-
era sensor
