Inappropriate route guidance may occur in

designated route guidance.
• If you set more than one 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 one or more of them.
• When a route cannot be searched.

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,
see page 116.
After replacing a tire, implement the
operation described in the “TIRE

PERIPHERAL MONITORING SYSTEM
CAUTION
●Do not use the system in the following
conditions:
• Outside of parking areas
• In unprepared parking area such as
gravel or sand
• In parking areas that are crooked or have level variations
• On slippery or icy roads, or in snow
• If the asphalt is melted due to harsh sunlight
• If there are obstacles in the target parking position (inside the blue
frame), or obstacles between the vehi-
cle and the parking space
• If there are a large number of vehicles or pedestrians passing
• In areas unsuitable for parking (overly small parking space, cliff etc.)
• If the image is hard to see due to dirt, direct sunlight, shadow or snow on the
camera lens
• If you are using tire chains or emer- gency tire(s)
● Do not use the system when the back
door is not completely closed.
CAUTION
● Do not use tires other than those
installed by the manufacturer, as the
system may not function correctly. Fur-
thermore, if you change the tires, there
may be errors in the positions of the
lines and frames displayed on the
screen. If you wish to change your tires,
see your Toyota dealer.
● In the following conditions, assisted
parking in the set parking position may
not be possible:
• The tires are extremely worn, or the
tire inflation pressure is low
• You are carrying an extremely heavy load
• There is a load in one side of the vehi- cle only, causing the vehicle to lean
• Tires have received a strong impact, such as bumping against a curb,
resulting in improper wheel alignment
If there is a large difference between the
set parking space and the vehicle posi-
tion in any situations other than those
above, consult with your Toyota dealer.
● Use your own eyes to confirm the vehi-
cle’s surroundings, as the displayed
image may become faint or dark, and
moving images will be distorted, or not
entirely visible when the outside temper-
ature is low. When backing up, be sure
to check behind and all around the vehi-
cle visually and with mirror before pro-
ceeding.
