vehicle maintains the HEV mode to
allow heating or air conditioning. The
mode does not change when the
driver presses the [HEV] button to
switch from the HEV mode to EV
mode whilst the heating and cooling
system is on and the coolant temper-
ature is below -14°C.

Hybrid Battery Cooling Duct
The hybrid battery cooling duct is
located on the left side of the rear
seats. The cooling duct cools down
the hybrid battery. When the hybrid
battery cooling duct is blocked, the
hybrid battery may be overheated.Do not obstruct the cooling duct with
any other objects.
Information
Clean the cooling duct for the hybrid bat-
tery with a dry cloth on a regular basis.
i
(Continued)
Do not put any objects into
the cooling duct of the hybrid
battery. Doing so may cause
loss of cooling duct volume to
the hybrid battery. When the
cooling duct is blocked with
any objects, immediately con-
tact your HYUNDAI dealer.
Never place a container of liq-
uid on or near the cooling
duct. If the liquid spills, the
hybrid battery located in the
luggage compartment may be
damaged.
Secure all loads in the lug-
gage compartment to prevent
them from being tossed about
before driving. When a sharp
or heavy load strike with a
strong impact or pierce the
interior luggage compartment
wall, the hybrid battery sys-
tem may be damaged, deterio-
rating its performance.
Never clean the cooling duct
of the hybrid battery with a
wet cloth. If any water enters
in the cooling duct of the
hybrid battery, the hybrid bat-
tery may cause an electric
shock, resulting in a serious
damage, an injury or a death.
The hybrid battery is com-
posed of lithium-ion polymer.
If the hybrid battery is improp-
erly handled, it is dangerous
to the environment. Also it
may cause electrical shock
and severe burns, resulting in
a serious injury or a death.
Do not spill liquid over the
cooling duct of the hybrid bat-
tery. Doing so is very danger-
ous. It may cause electric
shock or serious injury.
Do not cover the cooling duct
with objects.
