AUX. BATTERY SAVER+ (For
Plug-in Hybrid, if equipped)
The Aux. Battery Saver+ is a function
that monitors the charging status of
the 12V auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges
the auxiliary battery.
✽ ✽
NOTICE
The Aux. Battery Saver+ function will
be ON when the vehicle is delivered. If
the function is not needed, you may
turn it off in the Users Settings mode
on the LCD display. For more infor-
mation, refer to the "System setting"
on the following page.
Mode

When the vehicle is OFF with all
doors, hood and liftgate closed, the
Aux. Battery Saver+ periodically acti-
vates according to the auxiliary bat-
tery status.

When the engine start/stop button is
in the ON position with the charging
connector plugged in, this function
activates according to the auxiliary
battery status to prevent over-dis-
charge of the auxiliary battery.
✽ ✽
NOTICE
The Aux. Battery Saver+ activates
for a maximum of 20 minutes. If the
Aux. Battery Saver+ function acti-
vates more than 10 times consecu-
tively, in the Automatic Mode, this
function will stop activating, judg-
ing that there is a problem with the
auxiliary battery. In this case, drive
the vehicle for some period of time.
The function will start activating if
the auxiliary battery returns to nor-
mal.
✽ ✽
NOTICE
If the Aux. Battery Saver+ function
was activated, the high voltage bat-
tery level may have decreased.
CAUTION
The Aux. Battery Saver+ func-
tion cannot prevent battery dis-
charge if the auxiliary battery is
damaged, worn out, used as a
power supply or if unauthorized
electronic devices are used.

System setting
The driver can activate the Aux.
Battery Saver+ function by placing
the engine start/stop button to the
ON position and by selecting:
"User Settings ➞Other Features ➞
Aux. Battery Saver+"WARNING
The Aux. Battery Saver+ relies
on the high voltage battery to
charge the 12V battery. The
charging indicator lamp will blink
rapidly when this is occurring.
To reduce the risk of electrical
shock, do not touch any high
voltage components (orange-
colored) or other electrical
devices while charging is occur-
ring.

H48
High Voltage Battery Air Intake
The hybrid battery air intake is locat-
ed on bottom and side of the rear
seats. The air intake cools down the
hybrid battery. When the hybrid bat-
tery air intake is blocked, the hybrid
battery may be overheated. Do not
obstruct the air intake with any other
objects.
If An Accident Occurs
Avoid the engine compartment.
Avoid making contact with any
orange or high voltage wires,
cables, or components.
Assume that a high voltage compo-
nent is exposed and move away from
the vehicle as promptly as possible.
Refer to Chapter 7 for towing infor-
mation.WARNING - Air Intake
Blocking the air intake behind
the rear seats may damage
the HEV battery.
Do not allow any water into
the air intake even when
cleaning. If any water enters
the air intake, the Hybrid bat-
tery may cause an electric
shock which can cause seri-
ous injury or death due to
electrocution.

WARNING
-
Interference with electron-
ic medical devices
Electromagnetic waves that are
generated from the charger can
impact medical electric devices
such as an implantable cardiac
pacemaker. When using such
medical electric devices, ask
your medical professional and
the device manufacturer
whether charging your electric
vehicle will impact the operation
of the medical electric devices.

✽
✽NOTICE
• Add fuel into the fuel tank within
20 minutes after opening the fuel
filler door. After 20 minutes, the
fuel tank may shut off, causing
fuel to overflow. In this case, re-
press the fuel filler door opening
button.
• Do not leave the fuel filler door opened for an extended period of
time. It may discharge the battery.
• Close the fuel filler door after fuel- ing the vehicle. If you start the
vehicle with the fuel filler door
opened, the message, “Check fuel
door”, illuminates on the LCD dis-
play.
Closing the fuel filler door
1. To install the cap, turn it clockwise
until it “clicks”. This indicates that
the cap is securely tightened.
2. Close the fuel filler door and push it lightly and make sure that it is
securely closed.
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.
✽ ✽ NOTICE
• There may be an intermittent
noise near the refueling hole while
the engine is idling if the fuel cap is
not closed securely. This occurs
normally with the OBD system.
• When refueling on unlevel ground, the fuel gauge may not
point to the F position.
It is not a malfunction. If you
move your vehicle to a level
ground, the fuel gauge will move
to the full position.
• Tighten the cap until it clicks once, otherwise the fuel cap open warn-
ing indicator light will illumi-
nate.
WARNING - For Plug-in
Hybrid
Avoid refueling the vehicle
while charging the (high-volt-
age) hybrid battery. It may
cause a fire or an explosion due
to static electricity.
WARNING
Before refueling, be sure to
check what type of fuel is used
for your vehicle.
If you put diesel fuel into a
gasoline-powered vehicle or
gasoline into a diesel-powered
vehicle, it may affect the fuel
system and cause serious dam-
age to the vehicle.

• When the charging system warning
light comes on due to low voltage
(when the alternator or battery
does not operate normally or mal-
function), the steering wheel may
require increased steering effort.Tilt and telescopic steering
Tilt and telescopic steering allows
you to adjust the steering wheel
before you drive. You can also raise it
to give your legs more space when
you get on or off the vehicle.
The steering wheel should be posi-
tioned so that it is comfortable for
you to drive, while permitting you to
see the instrument panel warning
lights and gauges.
To change the steering wheel angle,
pull down the lock-release lever (1),
adjust the steering wheel to the
desired angle (2) and height (3) then
pull up the lock-release lever to lock
(4) the steering wheel in place. Be
sure to adjust the steering wheel to
the desired position before driving.
✽ ✽
NOTICE
After adjustment, sometimes the
lock release lever may not lock the
steering wheel. It is not a malfunc-
tion. This occurs when two gears are
not engaged correctly. In this case,
adjust the steering wheel again and
then lock the steering wheel.
WARNING- Steering
wheel adjustment
Never adjust the angle and
height of the steering wheel
while driving. You may lose
steering control.
