2015 Hyundai Equus engine

Maintenance
84 7
• 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.Operating precautions for catalyt-
ic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
• Make sure to refuel your vehicle
according to the "Fuel require-
ments" suggested in section 1.
• Do not operate the vehicle when
there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
• 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 con-
trol system. All inspections and
adjustments must be made by an
authorized HYUNDAI dealer.
WARNING- Fire
• A hot exhaust system can
ignite flammable items under
your vehicle. Do not park, idle,
or drive the vehicle over or
near flammable objects, such
as grass, vegetation, paper,
leaves, etc.
• The exhaust system and cat-
alytic system are very hot
while the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic, you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle or do not coat the
vehicle for corrosion control.
It may present a fire risk under
certain conditions.

Maintenance
• 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 catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.

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 economy 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.

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 viscosi-
ty 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.
CAUTION
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.
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.
