{CAUTION
Idling a vehicle in an enclosed
area with poor ventilation is
dangerous. Engine exhaust may
enter the vehicle. Engine exhaust
contains Carbon Monoxide (CO)
which cannot be seen or smelled.
It can cause unconsciousness
and even death. Never run the
engine in an enclosed area that
has no fresh air ventilation.
For more information, seeEngine
Exhaust on page 2-31.

running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle will
not move, even when it is on
fairly level ground, always set
the parking brake and move the
automatic transmission shift lever
to P (Park), or the manual
transmission shift lever to Neutral.Follow the proper steps to be
sure the vehicle will not move.

Object Detection
Systems
Rear Vision
Camera (RVC)
Vehicles with the rear vision camera
system are designed to help the
driver while the vehicle is backing
up. The area behind the vehicle
is displayed on the screen in the
inside rear view mirror. Read this
entire section before using the
camera system.
When the key is in the ON/RUN
position and the driver shifts the
vehicle into R (Reverse), the video
image appears from inside the
rear view mirror. Once the vehicle
is shifted out of R (Reverse),
the image disappears.
The display may have a guideline
overlay that can help the driver align
the vehicle when backing into a
parking spot.Turning the Rear Vision Camera
System On or Off
To turn off the rear vision camera
system, press and hold
z, located
on the inside rearview mirror,

system on again, press and
hold
zuntil the left indicator light
illuminates. The rear vision
camera system display is now
enabled and the display will appear
in the mirror normally.
{CAUTION
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
Detect objects that are
outside the camera’s eld of
view, below the bumper, or
underneath the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
Do not back the vehicle by only
looking at the rear vision camera
screen, or use the screen during
longer, higher speed backing
maneuvers or where there could
be cross-traffic. Your judged
distances using the screen will
differ from actual distances.

CAUTION (Continued)
So if you do not use proper care
before backing up, you could
hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in
vehicle damage, injury, or death.
Even though the vehicle has the
RVC system, always check
carefully before backing up by
checking behind and around
the vehicle.Rear Vision Camera Location
The image on the screen is provided
by the camera located on the rear
bumper.The image from the camera that
appears on the screen appears
farther than the actual distance.
The area displayed by the camera
is limited. The camera does not
display objects which are close to
either corner of the bumper or under
the bumper. On the H3, the spare
tire and carrier extends rearward
of the rear bumper. The area
displayed on the screen may vary
according to vehicle orientation
or road conditions. View of H3 Camera Location

Features and Controls 2-37

The following illustration shows the
eld of view that the camera
provides.Notice:The spare tire extends
farther away from rear of the
vehicle than the trailer hitch
shown on rear vision camera
display. The spare tire could hit
an object even though there
appears to be enough distance
on the display between the trailer
hitch and objects behind you
causing vehicle or property
damage. Do not use this system
to judge the distance between
the spare tire and objects
behind you.
