Diesel engine
Diesel fuel
Diesel engine must be operated only on
commercially available diesel fuel that
complies with EN 590 or comparable
standard. (EN stands for “European
Norm”). Do not use marine diesel fuel,
heating oils, or non-approved fuel
additives, as this will increase wear and
cause damage to the engine and fuel
system. The use of non-approved fuels
and / or fuel additives will result in a
limitation of your warranty rights.
Diesel fuel of above cetane 51 is used
in your vehicle. If two types of diesel
fuel are available, use summer or winter
fuel properly according to the following
temperature conditions.
• Above -5°C (23°F) ... Summer type
diesel fuel.
• Below -5°C (23°F) ... Winter type diesel
fuel.
Watch the fuel level in the tank very
carefully : If the engine stop s through
fuel failure, the circuits must be
completely purged to permit restarting.
CAUTION
Do not let any petrol or water enter the
tank. This would make it necessary to
drain it out and to bleed the lines to
avoid jamming the injection pump and
damaging the engine.
CAUTION
Diesel Fuel (if equipped with DPF)
It is recommended to use the regulated
automotive diesel fuel for diesel vehicle
equipped with the DPF system.
If you use diesel fuel including high
sulfur (more than 50 ppm sulfur) and
unspecified additives, it can cause the
DPF system to be damaged and white
smoke can be emitted.
Biodiesel
Commercially supplied Diesel blends of
no more than 7% biodiesel, commonly
known as “B7 Diesel” may be used
in your vehicle if Biodiesel meets EN
14214 or equivalent specifications. (EN
stands for “European Norm”). The use
of biofuels exceeding 7% made from
rapeseed methyl ester (RME), fatty
acid methyl ester (FAME), vegetable oil
methyl ester (VME) etc. or mixing diesel
exceeding 7% with biodiesel will cause
increased wear or damage to the engine
and fuel system. Repair or replacement
of worn or damaged components due to
the use of non approved fuels will not be
covered by the manufactures warranty.
CAUTION
• Never use any fuel, whether diesel,
B7 biodiesel or otherwise, that fails
to meet the latest petroleum industry
specification.
• Never use any fuel additives
or treatments that are not
recommended or approved by the
vehicle manufacturer.

Vehicle information
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.

CAUTION
Always be sure to clean the area around any filler plug, drain plug, or dipstick
before checking 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.
An engine oil displaying this American Petroleum Institute(API)
Certification Mark conforms to the International Lubricant
Specification Advisory Committee (ILSAC). It is recommended to only
use engine oils that uphold this API Certification Mark.

Charging System
Warning Light
This warning light illuminates:
• Once you set the ignition switch or
Engine Start/Stop button to the ON
position.
- It remains on until the engine is
started.
• When there is a malfunction with
either the alternator or electrical
charging system.
If there is a malfunction with either
the alternator or electrical charging
system:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
alternator drive belt for looseness or
breakage.
If the belt is adjusted properly, there
may be a problem in the electrical
charging system.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer as soon as
possible.
Engine Oil Pressure
Warning Light
This warning light illuminates:
• Once you set the ignition switch or
Engine Start/Stop button to the ON
position.
- It remains on until the engine is
started.
• When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. Turn the engine off and check the
engine oil level (For more details, refer
to “Engine Oil” in chapter 9). If the
level is low, add oil as required.
If the warning light remains on after
adding oil or if oil is not available, we
recommend that you have the vehicle
inspected by an authorized HYUNDAI
dealer as soon as possible.
