✽NOTICE
HID lamps have superior perform-
ance vs. halogen bulbs.
HID lamps are estimated by the
manufacturer to last twice as long or
longer than halogen bulbs depend-
ing on their frequency of use. They
will probably require replacement
at some point in the life of the vehi-
cle. Cycling the headlamps on and
off more than typical use will short-
en HID lamps life. HID lamps do not
fail in the same manner as halogen
incandescent lamps. If a headlamp
goes out after a period of operation
but will immediately relight when
the headlamp switch is cycled it is
likely the HID lamp needs to be
replaced. HID lighting components
are more complex than conventional
halogen bulbs thus have higher
replacement cost.
✽NOTICE
We recommend that the headlamp
aiming be adjusted after an accident
or after the headlamp assembly is
reinstalled at a HYUNDAI autho-
rised repairer.

Static bending lamp
1.Turn off the engine.
2.Open the bonnet. HID Headlamp low beam
(if equipped)
Do not attempt to replace or
inspect the low beam (XENON
bulb) due to electric shock dan-
ger. If the low beam (XENON
bulb) is not working, have your
vehicle checked by a HYUNDAI
authorised repairer.

Maintenance
3. Exhaust emission control
system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
whilst maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
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 gas precautions
(carbon monoxide)
• Carbon monoxide can be present
with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately.• Do not operate the engine in con-
fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in or
out of the area.
• When the vehicle is stopped in an
open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
• Never sit in a parked or stopped
vehicle for any extended time with
the engine running.
• When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to
the emission control system. Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colourless and odourless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poison-
ing.

Specifications & Consumer information
Recommended SAE viscosity
number Engine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flow ability). Lower viscos-
ity engine oils can provide better fuel
economy and cold weather perform-
ance; however, higher viscosity
engine oils are required for satisfac-
tory 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 tempera-
ture your vehicle will be operated in
before the next oil change. Proceed
to select the recommended oil vis-
cosity from the chart.
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.

*1: For better fuel economy, it is recommended to use the engine oil of a viscosity
grade SAE 5W-30 (API SM/ILSAC GF-4 (For 3.0L, 3.3L, 3.8L)/ACEA A5).
However, if the engine oil is not available in your country, select the proper engine
oil using the engine oil viscosity chart.
