Fuse switch
Always, place the fuse switch to the
ON position.
If you move the switch to the OFF
position, some items such as the
audio system and digital clock must
be reset and the smart key may not
work properly.

Engine compartment panel
fuse replacement
1. Turn the hybrid system off.
2. Turn all other switches OFF.
3. Remove the fuse panel cover by pressing the tap and pulling up.
4. Check the removed fuse; replace it if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
5. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized HYUNDAI dealer.

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Vehicle modifications
This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust (carbon monox-ide) precautions
Carbon monoxide can be present
with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.

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
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.
Temperature Range for SAE Viscosity Numbers
Temperature -30 -20 -10 0 10 20 30 40 50
-10 0 20 40 60 80 100 120
Engine Oil *110W-30
5W-20, 5W-30
°C
(°F)
*1For better fuel economy, it is recommended to use the
engine oil of a viscosity grade SAE 5W-20 (API SM / ILSAC
GF-4). However, if the engine oil is not available in your
country, select the proper engine oil using the engine oil
viscosity chart.

5. Remove any dust on the charging
connector and charging inlet.
6. Hold the charging connector han- dle. Then, insert it into the charg-
ing inlet, until you hear a click
sound. If it is not fully connected, a
bad connection between the
charging connector and the charg-
ing terminals may cause a fire. 7. Check if the charging cable con-
nection indicator of the high volt-
age battery in the instrument clus-
ter is turned ON.
Charging does not occur when the
indicator is OFF. When the charg-
ing connector is not connected
properly, reconnect the charging
cable to charge.
Information
• The charging is in progress only with the shift lever is in P (Park).
Charging the battery with the
Engine Start/Stop button in the
ACC position is possible. However,
it may discharge the 12-V battery.
Thus, if possible, charge the battery
with the Engine Start/Stop button in
the OFF position.
• Moving the shift lever from P (Park) to R (Reverse)/N(Neutral)/D (Drive)
stops the charging process.
To restart the charging process,
move the shift lever to P (Park),
press the Engine Start/Stop button
to the OFF position, and disconnect
the charging cable. Then, connect
the charging cable.

estimated charging time is dis-
played on the instrument cluster
for about 1 minute. It is also dis-
played, when the driver’s door is
opened with charging in progress.
When scheduled charging is set,
the estimated charging time is dis-
played as "--".
