Power Outlet
The power outlet is designed to pro-
vide power for 12V accessories or
other devices designed to operate
with vehicle electrical systems. The
devices should draw less than 180 W
with the vehicle in the ready ( )
mode.To prevent damage to the Power
Outlets :
Use the power outlet only when
the vehicle is in the ready ()
mode and remove the accessory
plug after use. Using the acces-
sory plug for prolonged periods
of time with the engine off could
cause the battery to discharge.
Only use 12V electric acces-
sories which are less than 180 W
in electric capacity.
Adjust the air-conditioner or
heater to the lowest operating
level when using the power outlet.
Close the cover when not in use.
Some electronic devices can
cause electronic interference
when plugged into a vehicle's
power outlet. These devices may
cause excessive audio static
and malfunctions in other elec-
tronic systems or devices used
in your vehicle. Push the plug in as far as it will
go. If good contact is not made,
the plug may overheat and the
fuse may open.
Plug in battery equipped electri-
cal/electronic devices with
reverse current protection. The
current from the battery may
flow into the vehicle's electri-
cal/electronic system and cause
system malfunction.
NOTICE
Avoid electrical shocks. Do not
place your fingers or foreign
objects (pin, etc.) into a power
outlet or touch the power outlet
with a wet hand.

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 accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately to
slow down the vehicle, but use the
paddle shifter (left side lever) to
increase regenerative braking con-
trol. Do not attempt to pull off the
road suddenly as this may cause
loss of vehicle control. When the
vehicle has slowed to such a speed
that it is safe to do so, brake care-
fully 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,
shift to P(Park), apply the parking
brake, and place the POWER but-
ton 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.
Follow the instructions provided
later in this chapter.
Confirm the EV Battery SOC
Level
Confirm that the vehicle is in P
(Park). The vehicle can only be
started when the gear is in P
(Park).
Confirm the State of Charge (SOC)
percentage level on the charge
gauge or in the head unit display.
Inspect the 12V auxiliary battery
connections in the EV motor com-
partment to make sure they are
clean and tight.
Turn on the headlamps. If the
headlamps are not illuminating
properly, the 12V auxiliary battery
voltage may be low.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.

What to do in an emergency
7. Connect the other end of the sec-
ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals or
the correct ground. Do not lean
over the battery when making
connections.
8. Start the motor of the assisting
vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
9. After your vehicle starts allow it to
operate at least 30 minutes with-
out shutting it down, this will help
charge back the 12V battery.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized HYUNDAI dealer.Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the
jumper cable from the black, neg-
ative (-) battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper
cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the
jumper cable from the red, positive
(+) jumper terminal of your vehicle
(1).
