●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.
● 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 the evening, or in other situations with
no light sources, the sides may not be
visible in wide mode.
● 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 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.207)

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:
P. 3 1 0
 After replacing a tire: P. 3 1 0
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.
