Vehicle driving controls
The Downhill Brake Control (DBC) feature assists the driver to descend down a steep
hill without having to depress the brake pedal.
The system automatically applies the brakes to maintain the vehicle speed of 4~40
km/h (2.5~25 mph) and allows the driver to concentrate on steering the vehicle down
hill.
Always turn off the DBC on normal roads. The DBC might activate inadvertently from
the stand by mode when driving through speed bumps or making sharp curves.
NOTE
The DBC defaults to the OFF position whenever the EV button is in ON position.
Noise or vibration may occur from the brakes when the DBC is activated.
The rear stop light comes on when DBC is activated.
