Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
Information
The headlamp and tail lamp lenses
could appear frosty if the vehicle is
washed after driving or the vehicle is
driven at night in wet weather. This
condition is caused by temperature
difference between the lamp inside
and outside and, it does not indicate a
problem with your vehicle. When
moisture condenses in the lamp, it will
be removed after driving with the
headlamp on. The removable level
may differ depending on lamp size,
lamp position and environmental con-
dition. However, if moisture is not
removed, we recommend that your
vehicle is inspected by an authorized
HYUNDAI dealer.
Headlamp, Parking Lamp, Turn
Signal Lamp and Side Marker
Type A – Standard type
(1) Headlamp (Low)
(2) Headlamp (High)
(3) Turn signal lamp
(4) Parking lamp
(5) Side marker
i
Prior to replacing a lamp,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the Engine Start/Stop button
to the OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.

Maintenance
Do not use strong soap, chemi-
cal detergents or hot water, and
do not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
Be careful when washing the
side windows of your vehicle.
Especially, with high-pressure
water, water may leak through
the windows and wet the interi-
or.
To prevent damage to the plastic
parts, do not clean with chemi-
cal solvents or strong deter-
gents.
To prevent damage to the charg-
ing door, make sure to close and
lock the vehicle doors when
washing (high-pressure wash-
ing, automatic car washing, etc.)
the vehicle.
High-pressure washing
When using high-pressure wash-
ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors
or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to
boots (rubber or plastic covers) or
connectors as they may be dam-
aged if they come into contact with
high pressure water. Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical cir-
cuits located in the engine com-
partment.
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.

Specifications, Consumer information and Reporting safety defects
Recommended SAE Viscosity
Number
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
CAUTION

*1: For better fuel economy, it is recommended to use the engine oil
of a viscosity grade SAE 0W-20 (API SN (or above) or ACEA
C2). However, if the engine oil is not available in your country,
select the proper engine oil using the engine oil viscosity chart.
10W-30
0/5W-20, 0/5W-30
Engine oil viscosity (thickness) has an effect on fuel economy and cold
weather operating (engine start and engine oil flowability). Lower viscosity
engine oils can provide better fuel economy and cold weather performance,
however, higher viscosity engine oils are required for satisfactory lubrication
in hot weather.
Using oils of any viscosity other than those recommended could result in
engine damage.
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change. Proceed to select the recommended
oil viscosity from the chart.

Action to be taken when charging stops abruptly
When the high voltage battery does not charge, check the followings:
1. Check the charging setting for the vehicle.
(e.g. When scheduled charging is set, charging is not initiated immediately when the AC charger or portable
charger (ICCB: In-Cable Control Box) is connected.)
2. Check the operation status of AC charger, portable charger.
(Charging Status Indicator Lamp for Portable Charger, refer to "Checking Charging Status" for trickle charge in
this chapter.)
❈Actual method for indicating the charging status may vary in accordance with the charger manufacturer.
3. When the vehicle does not charge and a warning message appears on the cluster, check the corresponding mes-
sage. Refer to "LCD Display Messages", in this chapter.
4. If the vehicle is properly charged when charged with another normally working charger, contact the charger man-
ufacturer.
5. If the vehicle does not charge when charged with another normally working charger, we recommend that you con-
tact an authorized HYUNDAI dealer for inspection.

Information
Clean the cooling duct for the hybrid
battery with a dry cloth on a regular
basis.
If an Accident Occurs
i
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 it
can cause an electrical shock,
injury or death may occur.
Any gas or electrolyte leakage
from your vehicle is not only
poisonous but also flamma-
ble. Upon witnessing one of
those, open the windows, and
remain a safe distance from
the vehicle out of the road.
Immediately contact an emer-
gency response team and
advise them that a hybrid vehi-
cle is involved.
(Continued)
WARNING
(Continued)
When the vehicle is severely
damaged, remain a safe dis-
tance of 50 feet (15 meter) or
more between your vehicle and
other vehicles/flammables.
If a fire occurs :
If a small scale fire occurs, use
a fire extinguisher (ABC, BC)
that is meant for electrical fires.
If it is impossible to extinguish
the fire in the early stage,
remain a safe distance from the
vehicle and immediately call
911. Also, advise them that an
electric vehicle is involved.
If the fire spreads to the high
voltage battery, large amount of
water is needed to put out the
fire. Using small amount of
water or fire extinguishers not
meant for electrical fires could
cause serious injury or death
from electrical shocks.

(Continued)
Do not put any objects into
the cooling duct of the hybrid
battery. Doing so may cause
loss of cooling duct volume to
the hybrid battery. When the
cooling duct is blocked with
any objects, immediately con-
tact your HYUNDAI dealer.
Never place a container of liq-
uid on or near the cooling
duct. If the liquid spills, the
hybrid battery located in the
luggage compartment may be
damaged.
Secure all loads in the luggage
compartment to prevent them
from being tossed about
before driving. If a sharp or
heavy load impacts or pierces
the interior luggage compart-
ment wall, the hybrid battery
system may be damaged, dete-
riorating its performance.

H55
When the Hybrid Vehicle Shuts
Off
When the high voltage battery is dis-
charged, when the 12-volt battery is
discharged, or when the fuel tank is
empty, the hybrid system may not
operate while driving. When the
Hybrid system does not operate, do
the followings:
1. Gradually reduce the vehicle
speed. Pull over your vehicle off
the road in a safe area.
2. Locate the shift lever in P (Park).
3. Turn ON the hazard warning flash-
ers.
4. Turn OFF the vehicle, and try to
start the hybrid system again,
while depressing the brake pedal
and turning on the Engine
Start/Stop button.5. When the hybrid system still does
not operate, refer to ''If the 12 Volt
Battery Is Discharged'' in chapter 6.
Before jump-starting the vehicle,
check the fuel level and the exact
procedure to jump start. For fur-
ther details, refer to ''If the 12 Volt
Battery Is Discharged'' in the
chapter 6. When the fuel level is
low, do not attempt to drive the
vehicle only with the battery
power. The high voltage battery
may be discharged, and the hybrid
system will turn OFF. When a submersion in water
occurs:
When your vehicle is flooded in
water, a high-voltage battery
may cause shock or fires. Thus,
turn the hybrid system OFF, take
the key in your possession and
escape to a safe place. Never
attempt physical contact with
your flooded vehicle.
Immediately contact an emer-
gency response team and
advise them that a hybrid vehi-
cle is involved.
