What to do in an emergency
If You Have a Flat Tire While
Driving
If a tire goes flat while you are driving:
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 loss of vehicle
control resulting in an accident.
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 median
area between the two traffic lanes.
When the vehicle is stopped, press the hazard warning flasher button,
move the shift lever into P (Park),
and apply the parking brake, and
place the Engine Start/Stop button
in the OFF position.
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.
When changing a flat tire, follow the instructions provided later in
this chapter.
Hybrid vehicle
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
replacement. It is lithium ion poly-
mer type integrated into the HEV
high voltage battery. The vehicle
has a 12V battery protection sys-
tem that cuts 12V battery from
vehicle draw to prevent full dis-
charge. If vehicle will not start, first
try pressing the 12V Battery Reset
switch (left side of the steering
wheel near the fuel door open
switch) to reconnect the 12V bat-
tery, but you must start vehicle
within 15 seconds of pressing the
12V Battery Reset switch. After
starting vehicle, operate the vehi-
cle safely outdoors in ready mode
stopped and/or drive it for 30 min-
utes total to charge the 12V battery
fully. Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, have
your vehicle checked by an author-
ized HYUNDAI dealer.

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 HEV high
voltage battery. The vehicle has a
12V battery 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), operate the vehicle safely
outdoors in ready mode stopped
and/or drive it for 30 minutes total
to charge the 12V battery fully. 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
engine 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 engine is running
or not. Although there is no engine-
sound, it is unnecessary to depress the
accelerator pedal.

What to do in an emergency
The following items may need to be
reset after the battery has been dis-
charged or the battery has been dis-
connected. See chapter 3 or 4 for:
Power Windows
Trip Computer
Climate Control System
Clock
Audio System
Sunroof
Driver Position Memory System
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.
If the power of the vehicle is shut
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 to the engine
compartment jumper terminals 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 to
touch.
2. Avoid fans or any moving parts in the engine compartment 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.
NOTICEJump 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.
