What to do in an emergency
Towing service
If emergency towing is necessary,
we recommend having it done by an
authorized HYUNDAI dealer or a
commercial tow-truck service.
Proper lifting and towing procedures
are necessary to prevent damage to
the vehicle. The use of wheel dollies
or flatbed is recommended.It is acceptable to tow the vehicle
with the rear wheels on the ground
(without dollies) and the front wheels
off the ground.
If any of the loaded wheels or sus-
pension components are damaged
or the vehicle is being towed with the
front wheels on the ground, use a
towing dolly under the front wheels.
When being towed by a commercial
tow truck and wheel dollies are not
used, the front of the vehicle should
always be lifted, not the rear.

Emergency Towing
(if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer or a
commercial tow truck service.If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the rear of the vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing should be done only on a
solid ground for a short distance and
at a low speed.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Always follow these emergency tow-
ing precautions:
Place the Engine Start/Stop button
in the ACC position so the steering
wheel is not locked.
Place the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
More steering effort will be required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your own to tow your vehicle.
The drivers of both vehicles should communicate with each other fre-
quently.
Before emergency towing, check that the hook is not broken or dam-
aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force.

What to do in an emergency
Use a towing cable or chain lessthan 16 feet (5 m) long. Attach a
white or red cloth (about 12 inches
(30 cm) wide) in the middle of the
cable or chain for easy visibility.
Drive carefully so the towing cable or chain remains tight during tow-
ing.
Before towing, check the automat- ic transmission for fluid leaks under
your vehicle. If the automatic trans-
mission fluid is leaking, flatbed
equipment or a towing dolly must
be used.

ODH063025
To avoid damage to your vehicle
and vehicle components when
towing:
Always pull straight ahead
when using the towing hooks.
Do not pull from the side or at
a vertical angle.
Do not use the towing hooks
to pull a vehicle out of mud,
sand or other conditions from
which the vehicle cannot be
driven out under its own
power.
Limit the vehicle speed to 10
mph (15 km/h) and drive less
than 1 mile (1.5 km) when tow-
ing to avoid serious damage
to the automatic transmis-
sion.

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 flammable.
Upon witnessing one of those,
open the windows, and remain
a safe distance from the vehi-
cle 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.

When the vehicle is severely
damaged, remain a safe dis-
tance of 50 feet (15 meter) 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.
