WARNING
■Cautions regarding the use of
the system
In order for this system to perform
as designed, the vehicle must be
driven safely and the driver must
control the speed to keep it within
operating parameters and to
avoid a collision.
As there is a limit to the degree of
control performance that this sys-
tem can provide, do not overly
rely on this system. The driver is
always responsible for paying
attention to the vehicle’s sur-
roundings and driving safely. This
system does not control braking
(or steering when in Guidance
mode). Driver needs to control
vehicle speed, control braking,
(and steering when in Guidance
mode,) and stop the vehicle to
avoid any collision. Failure to fol-
low this warning could result in
property damage, serious injury
or death.
■When using the Trailer
Backup Guide
For proper system performance,
observe the following precautions.
Failure to do so may lead to an
accident resulting in property
damage, serious injury, or death.
●Keep the tailgat e fully latched.
●Keep the rear camera clean at
all times.
●Do not change the installation
position or direction of the rear
camera or remove it.
●Do not modify the trailer hitch
light. (→P.386)
●Make sure nothing can obstruct
the rear camera view of the
trailer.
The system is designed to oper-
ate in various weather and lighting
conditions and on different ground
surfaces (asphalt , grass, gravel,
etc.), however performance can
still be affected by various envi-
ronmental factors (e.g. shadow
passing over the tr ailer or dimin-
ished contrast between trailer and
the ground leading to trailer
detection being lost, etc.) so
always drive carefully, remain
alert and aware of your surround-
ings, and do not overly rely on the
system.
