Maintenance
• Do not operate the engine in confined
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 vehi-
cle 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.Operating precautions for catalytic
converters (if equipped)Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
• Make sure to refuel your vehicle
according to the "Fuel requirements"
suggested in section 1.
• Do not operate the vehicle when there
are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.
• Do not misuse or abuse the engine.
Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off.
• Do not operate the engine at high idle
speed for extended periods (5 minutes
or more).
• Do not modify or tamper with any part
of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorized
HYUNDAI dealer.
• Avoid driving with a very low fuel level.
If you run out of gasoline, it could
cause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.
WARNING- Fire
• A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park, idle, or drive the
vehicle over or near flammable
objects, such as grass, vegeta-
tion, paper, leaves, etc.
• The exhaust system and catalytic
system are very hot while the
engine is running or immediately
after the engine is turned off. Keep
away from the exhaust system
and catalytic, you may get burned.
Also, do not remove the heat sink
around the exhaust system, do
not seal the bottom of the vehicle
or do not coat the vehicle for cor-
rosion control. It may present a
fire risk under certain conditions.

Refer to “Fuel requirements” in section 1
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*
1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ-
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year’s time, they can offer significant cost and energy savings.
*
3: If the API service SM or ACEA A5 engine oil is not available in your country, you are able to use API service SL or ACEA A3.

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
flowability). Lower viscosity engine oils
can provide better fuel economy and cold
weather performance, however, higher
viscosity engine oils are required for sat-
isfactory lubrication in hot weather. Using
oils of any viscosity other than those rec-
ommended could result in engine dam-
age.
CAUTION
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or drain-
ing 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.
When choosing an oil, consider the range of temperature your vehicle will be operat-
ed in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.
