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:
