WARNING
∙ Failure to follow the warnings and in-structions for proper use of the RearView
Monitor system could result in serious in-
jury or death.
∙ RearView Monitor is a convenience fea- ture and is not a substitute for proper
backing. Always turn and look out the
windows and check mirrors to be sure
that it is safe to move before operating
the vehicle. Always back up slowly.
∙ The system is designed as an aid to the driver in showing large stationary ob-
jects directly behind the vehicle, to help
avoid damaging the vehicle.
∙ The distance guide line and the vehicle width line should be used as a reference
only when the vehicle is on a level paved
surface. The distance viewed on the
monitor is for reference only and may be
different than the actual distance be-
tween the vehicle and displayed objects.
CAUTION
Do not scratch the camera lens when clean-
ing dirt or snow from the front of the
camera. The RearView Monitor system automatically
shows a rear view of the vehicle in the upper
touch-screen display (upper display) when
the shift lever is shifted into the R (Reverse)
position. When activating the RearView
Monitor, the guide lines, the icons and the
messages may not be displayed immediately.
The radio can still be heard while the Rear-
View Monitor is active.
To display the rear view, the RearView Moni-
tor system uses a camera located just above
the vehicle’s license plate

may be displayed incorrectly. If this oc-
curs, please perform the following
procedures:
– Turn the steering wheel from lock to lock while the engine is running.
– Drive the vehicle on a straight road for more than 5 minutes.

WARNING
∙ Failure to follow the warnings and in-structions for the proper use of the
Around View® Monitor system could re-
sult in serious injury or death.
∙ The Around View® Monitor is a conve- nience feature and is not a substitute for
proper vehicle operation because it has
areas where objects cannot be viewed.
The four corners of the vehicle in particu-
lar, are areas where objects do not al-
ways appear in the bird’s-eye, front, or
rear views. Always check your surround-
ings to be sure that it is safe to move
before operating the vehicle. Always op-
erate the vehicle slowly.
∙ The driver is always responsible for safety during parking and other
maneuvers.
CAUTION
Do not scratch the camera lens when clean-
ing dirt or snow from the front of the
camera.
The Around View® Monitor system is de-
signed as an aid to the driver in situations
such as slot parking or parallel parking. The monitor displays various views of the
position of the vehicle in a split screen format.
Not all views are available at all times.
Available views:
∙ Front View An approximately 150–degree view of
the front of the vehicle.
∙ Rear View An approximately 150–degree view of
the rear of the vehicle.
∙ Bird’s-Eye View The surrounding views of the vehicle
from above.
∙ Front-Side View The view around and ahead of the front
passenger’s side wheel.
∙ Front-Wide View An approximately 180–degree view of
the front the vehicle.
∙ Rear-Wide View An approximately 180–degree view of
the rear of the vehicle. To display the multiple views, the Around
View® Monitor system uses cameras located
in the front grille, on the vehicle’s outside
mirrors and one just above the vehicle’s li-
cense plate

WARNING
∙ The air conditioner cooling function op- erates only when the engine is running.
∙ Do not leave children or adults who would normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acciden-
tally injure themselves or others through
inadvertent operation of the vehicle.
Also, on hot, sunny days, temperatures in
a closed vehicle could quickly become
high enough to cause severe or possibly
fatal injuries to people or animals.
∙ Do not use the recirculation mode for long periods as it may cause the interior
air to become stale and the windows to
fog up.
