RAB SYSTEM LIMITATIONS
WARNING
Listed below are the system limita-
tions for the RAB system. Failure to
follow the warnings and instructions
for proper use of the RAB system
could result in serious injury or
death.
. When the vehicle approaches an
obstacle while the accelerator or
brake pedal is depressed, the
function may not operate or the
start of the operation may be
delayed. The RAB system may
not operate or may not perform
sufficiently due to vehicle condi-
tions, driving conditions, the traf-
fic environment, the weather,
road surface conditions, etc. Do
not wait for the system to oper-
ate. Operate the brake pedal by
yourself as soon as necessary.
. If it is necessary to override RAB
operation, strongly press the ac-
celerator pedal.
. Always check your surroundings
and turn to check what is behind
you before and while backing up.

ary objects behind the vehicle.
