changed as follows :
The seat warmer defaults to the OFF
position whenever the POWER button
is placed in the ON position.

With the seat warmer switch in the
ON position, the heating system in the
seat turns off or on automatically
depending on the seat temperature.
Battery cooling duct
The high voltage battery cooling duct
is located in the bottom center of the
rear seats. The cooling duct cools
down the high voltage battery.
When the high voltage battery cool-
ing duct is blocked, the high voltage
battery may be overheated. Do not
obstruct the cooling duct with any

State of Charge (SOC) gauge forhigh voltage battery
The SOC gauge shows the charging
status of the high voltage battery.
"L (Low)" position on the indicator
indicates that there is not enough
energy in the high voltage battery. "H
(High)" position indicates that the
driving battery is fully charged.
When driving on highways or motor-
ways, make sure to check in advance
if the driving battery is charged
enough. When there are 2~3 gauge bars
(near the "L (Low)" area) on the SOC
gauge, the warning lamp turns ON to
alert you of the battery level.
When the warning lamp turns ON,
the vehicle can drive an additional
12~18 miles (20~30 km) depending
on the driving speed, heater/air con-
ditioner, weather, driving style, and
other factors. Charging is required.When there are 1-2 gauge bars left
for the high voltage battery, the
vehicle speed is limited and then
eventually the vehicle will turn OFF.
Charge the vehicle immediately.
