Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type ofcoolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolantin accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.Check battery and cables
The winter temperature increases
the battery consumption.
Inspect
the battery and cables, as speci-
fied in the chapter 7. The battery
charging level can be checked by an
authorized HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer. Check spark plugs and ignitionsystem
Inspect the spark plugs, as speci-
fied in the chapter 7.
If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury.

What to do in an emergency

For your safety, do not touch
high voltage cables, connec-
tors and package modules.
High voltage components are
orange in color.
Exposed cables or wires may
be visible inside or outside of
the vehicle. Never touch the
wires or cables, because an
electrical shock, an injury, or a
death may occur.
Any gas or electrolyte leakage
from your vehicle is not only
poisonous but also flamma-
ble. Upon witnessing one of
those, open the windows, and
remain a safe distance from
the vehicle out of the road.
Immediately contact an
authorized HYUNDAI dealer
and advise them that a hybrid
vehicle is involved.
If you need towing, refer to
"Towing" in the previous
pages. (Continued)
(Continued)
When the vehicle is severely
damaged, remain a safe dis-
tance of 15 meter (50 feet) or
more between your vehicle
and other vehicles/flamma-
bles.
WARNING
If a fire occurs :
Upon witnessing any sparks,
gases, flames, or fuel leakage of
your vehicle, immediately call
911 or contact an authorized
HYNDAI dealer. Also, advise
them that a hybrid vehicle is
involved.
WARNING
When a submersion in water
occurs:
When your vehicle is flooded in
water, a high-voltage battery
may cause shock or may catch
on fire. Thus, turn the hybrid
system OFF, take the key in
your possession and move to a
safe place. Never attempt phys-
ical contact with your flooded
vehicle. Immediately contact an
authorized HYUNDAI dealer and
advise them that a hybrid vehi-
cle is involved.
