- The temperature of the motor or high voltage battery is too high or
too low
- There is a problem with the cooling system, or a failure that may inter-
rupt normal driving Do not accelerate or start the
vehicle suddenly when the
power down warning light is ON.
When the high voltage battery level is low, the power downwarning illuminates and the
power output from the vehicle is
limited. Charge the battery
immediately since your vehicle
may not drive uphill or skid on aslope with the warning light ON.

Aux. Battery Saver+
The Aux. Battery Saver+ is a function that monitors the charging status of
the 12 V auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges
the auxiliary battery.Information
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may
turn it off in the Users Settings mode
on the cluster. For more information,
refer to the following page.
Mode
Cycle Mode :
When the POWER button is in the
OFF or ACC position with all doors,
hood and tailgate closed, the Aux.
Battery Saver+ activates according
to the auxiliary battery status.
Automatic Mode :
When the POWER button is in the OFF position with the charging con-nector plugged in, the function acti-
vates according to the auxiliary bat-
tery status to prevent overdischarge
of the auxiliary battery. Information
 The Aux. Battery Saver+ activates maximum of 60 minutes. If the Aux.
Battery Saver+ function activates
more than 10 times consecutively
when in the automatic mode, the
function will stop activating, judg-
ing that there is a problem with the
auxiliary battery. In this case, drive
the vehicle for some period of time
or if the auxiliary battery returns to
normal, the function will start acti-
vating.
 The Aux. Battery Saver+ function cannot prevent battery discharge if
the auxiliary battery is damaged,
worn out, used as a power supply or
unauthorized electronic devises are
used.
 If the Aux. Battery Saver+ function was activated, the high voltage bat-
tery level may have decreased. i
