The vehicle's high- voltage on-board electrical
system is under high voltage. If you modify
component parts in theve hicle's high- voltage
on-board electrical system or touch damaged
component parts, you may be electrocuted. In
addition, modi/ed and/or damaged compo-

Have the components of the high-voltage
on-board electrical system checked at a

re placed if necessar y. The components of
the high-voltage on-board
electrical system are mar ked with yellow warning
stic kers. The cables of the high-voltage on-board
electrical system are orange.
Ve hicles with hybrid systems generate signi/-
cant lyless noise when stationary and when being
driven than vehicles with combustion engines.
When driving in elect ric mode, theve hicle may
not be heard by otherroad users due tothe signif-
icantly reduced noise generated. It is
forth is reason that theve hicle is equipped
with a sound generator, which ser ves as an acous-
tic vehicle alerting system (A VAS).

Depending on the accident situation, the post-col-

collision or even avo id it. If an accident is de
tected, the post-collision brake
can implement automatic braking. When theve hi-
cle has come toa standstill, the electric parking
brake is automatically applied.
The driver can cancel automatic braking bytaking
