●Never depend on the rear view monitor
system entirely when backing up. The
image and the position of the guide lines
displayed on the screen may differ from
the actual state.
Use caution, just as you would when
backing up any vehicle.
● Be sure to back up slowly, depressing
the brake pedal to control vehicle speed.
● The instructions given are only guide-
lines. When and how much to turn the
steering wheel will vary according to
traffic conditions, road surface condi-
tions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of
this before using the rear view monitor
system.
● When parking, be sure to check that the
parking space will accommodate your
vehicle before maneuvering into it.
WA R N I N G
●Do not use the rear view monitor system
in the following cases:
• On icy or slick road surfaces, or in
snow
• When using tire chains or emergency tires
• When the back door is not closed com- pletely
• On roads that are not flat or straight,
such as curves or slopes.
● In low temperatures, the screen may
darken or the image may become faint.
The image could distort when the vehi-
cle is moving, or you may become
unable to see the image on the screen.
Be sure to visually check all around the
vehicle both directly and using the mir-
rors before proceeding.
● If the tire sizes are changed, the position
of the fixed guide lines displayed on the
screen may change.
● The camera uses a special lens. The
distances between objects and pedestri-
ans that appear in the image displayed
on the screen will differ from the actual
distances. ( P.158)

NAVIGATION SYSTEM

Accurate current position may not be
shown in the following cases:
• When driving on a small angled Y-
shaped road.
• When driving on a winding road.
• When driving on a slippery road such as in sand, gravel, snow, etc.
• When driving on a long straight road.
• When freeway and surface streets run in parallel.
• After moving by ferry or vehicle carrier.
• When a long route is searched during high speed driving.
• When driving without setting the current position calibration correctly.
• After repeating a change of direction by going forward and backward, or turning
on a turntable in a parking lot.
• When leaving a covered parking lot or parking garage.
• When a roof carrier is installed.
• When driving with tire chains installed.
• When the tires are worn.
• After replacing a tire or tires.
• When using tires that are smaller or larger than the factory specifications.
• When the tire pressure in any of the 4
tires is not correct. 
Inappropriate route guidance may occur in
the following cases:
• When turning at an intersection off the
designated route guidance.
• If you set more than 1 destination but skip any of them, auto reroute will dis-
play a route returning to the destination
on the previous route.
• When turning at an intersection for which there is no route guidance.
• When passing through an intersection for which there is no route guidance.
• During auto reroute, the route guidance
may not be available for the next turn to
the right or left.
• During high speed driving, it may take a long time for auto reroute to operate. In
auto reroute, a detour route may be
shown.
• After auto reroute, the route may not be changed.
• If an unnecessary U-turn is shown or announced.
• If a location has multiple names and the
system announces 1 or more of them.
• When a route cannot be searched.
• If the route to your destination includes
gravel, unpaved roads or alleys, the
route guidance may not be shown.
• Your destination point might be shown
on the opposite side of the street.
• When a portion of the route has regula- tions prohibiting the entry of the vehicle
that vary by time or season or other rea-
sons.
• The road and map data stored in the
navigation system may not be complete
or may not be the latest version.
 If the vehicle cannot receive GPS sig-
nals, the current position can be
adjusted manually. For information on
setting the current position calibration:

INFORMATION
●This navigation system uses tire turning
data and is designed to work with fac-
tory-specified tires for the vehicle.
Installing tires that are larger or smaller
than the originally equipped diameter
may cause inaccurate display of the cur-
rent position. The tire pressure also
affects the diameter of the tires, so make
sure that the tire pressure of all 4 tires is
correct.
