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.

(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.

H53
When the Hybrid Vehicle Shuts
Off
When the high voltage battery is dis-
charged, when the 12-volt battery is
discharged, or when the fuel tank is
empty, the hybrid system may not
operate while driving. When the
Hybrid system does not operate, do
the followings:
1.Gradually reduce the vehicle
speed. Pull over your vehicle off
the road in a safe area.
2. Locate the shift lever in P (Park).
3. Turn ON the hazard warning flashers.
4.Turn OFF the vehicle, and try to
start the hybrid system again,
while depressing the brake pedal
and turning on the ignition switch.5.When the hybrid system still does
not operate, refer to "If the 12 Volt
Battery Is Discharged" in chapter 6.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For further
details, refer to "If the 12 Volt
Battery Is Discharged" in the chap-
ter 6. When the fuel level is low, do
not attempt to drive the vehicle only
with the battery power. The high
voltage battery may be discharged,
and the hybrid system will turn OFF.When a submersion in water
occurs:
When your vehicle is flooded in
water, a high-voltage battery
may cause shock or fires. Thus,
turn the hybrid system OFF, take
the key in your possession and
escape to a safe place. Never
attempt physical contact with
your flooded vehicle.
Immediately contact an author-
ized HYUNDAI dealer and advise
them that a hybrid vehicle is
involved.
