If you have a flat tire while driving
If a tire goes flat while you are driv- ing:
1. Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-ately or attempt to pull off the road
as this may cause a loss of con-
trol. When the vehicle has slowed
to such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the medi-
an area between the two traffic
lanes.
2. When the vehicle is stopped, turn on your emergency hazard flash-
ers, set the parking brake and shift
gear to the P(Park) position.
3. Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
If the vehicle stalls while driv- ing
1. Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the vehicle again. If your vehicle will not start, contact
an authorized HYUNDAI dealer. Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
This vehicle does not have a regu- lar 12V battery that needs periodic

12V Battery Reset switch (left side
of the steering wheel near the fuel
door open switch) to reconnect the
12V battery, but you must start
vehicle within 15 seconds of press-
ing the 12V Battery Reset switch.
After starting vehicle, operate the
vehicle safely outdoors in ready
mode stopped and/or drive it for 30
minutes total to charge the 12V
battery fully.

Before Jump Starting
This vehicle does not have a regular
12V battery that needs periodic
replacement. It is lithium ion polymer
type integrated into the high voltage
battery. The vehicle has a 12V bat-
tery protection system that cuts 12V
battery from vehicle draw to prevent
full discharge.
Using the 12V Battery ResetSwitch
1. Press the 12V Battery Reset switch to reconnect the 12V bat-
tery.
2. Start the vehicle within 15 sec- onds of pressing the 12V Battery
Reset switch.
3. After starting vehicle ( indica- tor on), move the vehicle outside
and keep the vehicle ready ( )
mode more than 30 minutes safe-
ly to charge the 12V battery. If you do not start the vehicle imme-
diately after pressing the 12V Battery
Reset switch, the power of 12V bat-
tery is automatically disconnected
after few seconds to save the 12V
battery from additional discharge. If
the 12V battery is disconnected prior
to starting the vehicle, press the 12V
Battery Reset switch again and then
immediately start the vehicle as
explained.
Repeated use of the 12V Battery
Reset switch without a sufficient
vehicle ON cycle (30 Min+) may
cause over discharge of the 12V bat-
tery, which will prevent the vehicle
from starting. If the 12V battery is
over discharged to a point that the
reset does not work, try to jump-start
the vehicle.
Information
After starting the vehicle ( indica-
tor on), the 12V battery is being
charged whether the accelerator pedal
is depressed or not.

External power source using 12V
battery
The use of external power acces-
sories may reduce performance
and function of the vehicle.
Especially, the use of dash cam-
eras may shut off the power of the
vehicle prior to the dash camera's
automatic shut-down.

off, start the vehicle as explained.
(refer to "Using the 12V Battery
Switch")Jump Starting
In the event vehicle still does not
have a functional 12V battery (check
if interior lights will not turn on) then
you can try a jump start using a 12V
booster pack or jumper cables from
another vehicle's 12V battery
according to the following instruc-
tions.1. Position the vehicles close enough
that the jumper cables will reach,
but do not allow the vehicles totouch.
2. Avoid fans or any moving parts in the fuel cell power module com-
partment at all times, even when
the vehicles are turned off.
3. Turn off all electrical devices such as radios, lights, air conditioning,
etc. Put the vehicles in P (Park)
and set the parking brake. Turn
both vehicles OFF.
NOTICE
Jump starting can be danger-
ous if done incorrectly. Follow
the jump starting procedure in
this section to avoid serious
injury or damage to your vehi-
cle. If in doubt about how to
properly jump start your vehi-
cle, we strongly recommend
that you have a service techni-
cian or towing service do it for
you.
