The power tailgate can be oper-ated when the vehicle is not run-
ning. However, the power tail-gate operation consumes a
large amount of electic power.
To prevent the battery from
being discharged, do not oper-
ate it excessively (e.g. more than
5 times repeatedly).
To prevent the battery from being discharged, do not leave
the power tailgate in the open
position for a long time.
Do not modify or repair any part of the power tailgate by yourself.
This must be done by an author-
ized HYUNDAI dealer.
When jacking up the vehicle to change a tire or repair the vehi-
cle, do not operate the power
tailgate. This could cause the
power tailgate to operate
improperly.
In cold and wet climates, the power tailgate may not work
properly due to freezing condi-tions.
Automatic reversal
During power opening and closing if
the power tailgate is blocked by an
object or part of the body, the power
tailgate will detect the resistance. If resistance is detected while open-
ing or closing the power tailgate, the
tailgate will stop and move in theopposite direction.
However, in some instances the
automatic reversal system may notdetect the object if it is too soft or is
very thin, or if the tailgate is almostfully closed near the latched position.
Caution should be taken to prevent
any objects from obstructing the tail-gate opeining. If the automatic reversal feature
operates more than 2 times whileattempting to open or close the tail-
gate, the power tailgate may stop at
that position. If this occurs, carefully
close the tailgate manually, and then
try to operate the power tailgateautomatically again.
NOTICE
OFE048039
Never intentionally place any
object or part of your body in
the path of the power tailgate to
make sure the automatic rever-sal operates.
WARNING
Do not put heavy objects on the
power tailgate before you oper-
ate the power tailgate feature.
Additional weight may damagethe operation of the system.

being charged by the regenerative
brakes (decelerating or driving on
a downhill road).
The more electric energy is
charged, the lower the gauge level.
ECO : It shows the energy con- sumption rate during normal driv-ing condition. POWER : It shows the energy con-
sumption rate of the vehicle when
driving uphill or accelerating. The
more electric energy is used, the
higher the gauge level.
