Trailer Backup Guide*
Trailer Backup Guide is a
system to assist when back-
ing up a trailer by providing
either (1) steering control to
assist backing up straight
(Straight Path Assist) or (2)
guidance for manual steer-
ing backup (Guidance
mode).
Trailer Backup Guide uses
the rear camera to detect
the trailer and a trailer hitch
light, which allows the
driver to use the system at
night time.
The system calculates the
trailer angle by image pro-
cessing from the rear cam-
era and calculates trailer
length and hitch length
during the trailer setup (cali-
bration) maneuver.

calibrate the trailer to improve per-
formance.
●The system is designed to be
used with the same trailer connec-
tion every time. If the ball mount
position is changed or reconfig-
ured or items are added to the
trailer tongue
after calibration, re-
calibration may be required.
Guidance mode provides a
“Trailer Direction” arrow that

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.

Owners Manual_USA_M0C052_en
off-road vehicles:
Drive your vehicle only in
areas where off-road vehicles
are permitted to travel.
 Respect private property. Get
owner’s permission before
entering private property.
 Do not enter areas that are
closed. Honor gates, barriers
and signs that restrict travel.
 Stay on established roads.
When conditions are wet,
driving techniques should be
changed or travel delayed to
prevent damage to roads.
■Additional information for
off-road driving
For owners in U.S. mainland,
Hawaii and Puerto Rico:
To obtain additional information
pertaining to driving your vehicle
off-road, consult the following
organizations.
 State and Local Parks and
Recreation Departments
 State Motor Vehicle Bureau
 Recreational Vehicle Clubs
 U.S. Forest Service and
Bureau of Land Management
WARNING
■Off-road driving precautions
Always observe the following pre-
cautions to minimize the risk of
death, serious injury or damage to
your vehicle:
●Drive carefully when off the
road. Do not take unnecessary
risks by driving in dangerous
places.
●Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel
and injure your hands. Keep
both hands and especially your
thumbs on the ou tside of the
rim.
●Always check your brakes for
effectiveness immediately after
driving in sand, mud, water or
snow.
●After driving through tall grass,
mud, rock, sand, rivers, etc.,
check that there is no grass,
bush, paper, rags, stone, sand,
etc. adhering or trapped on the
underbody. Clear off any such
matter from the underbody. If
the vehicle is used with these
materials trapped or adhering to
the underbody, a breakdown or
fire could occur.
●In a rollover crash, an unbelted
person is significantly more
likely to die than a person wear-
ing a seat belt. Therefore, the
driver and all passengers
should fasten their seat belts
whenever the vehicle is moving.
●When driving off-road or in rug-
ged terrain, do not drive at
excessive speeds, jump, make
sharp turns, strike objects, etc.
This may cause loss of control
or vehicle rollover causing
death or serious injury. You are
also risking expensive damage
to your vehicle’s suspension
and chassis.
