OPERATION
ӹ
DEF filler cap is located on the left side of the engine
compartment.
ӹ
To open: Switch off the ignition.
ӹ
Open the hood.
ӹ
Turn filler cap counter-clockwise and remove it.
ӹ
To close: Replace cap on the filler neck and turn it clockwise.
You will hear a click when cap is fully closed.
ӹ
Close the hood.
If the fuel tank has been run dry, after refueling carry
out the following steps:
ӹ
Before starting the engine: Switch on the ignition three or
four times.
ӹ
Turn the key to position 2 in the ignition lock. The preglow
indicator lamp in the instrument cluster lights up briefly.
ӹ
Once the preglow indicator lamp goes out, turn the key
to position 3 in the ignition lock and release it as soon as the
engine is running .
You can start the diesel engine without preglow when the
engine is warm.
DIESEL EXHAUST FLUID (DEF)
The Diesel Exhaust fluid (DEF) is an emissions control
liquid required by modern diesel engines. It is injected into
the exhaust stream. DEF is never added to diesel fuel, it is
a non-hazardous solution of 32.5% urea in 67.5% de-ionized
water. DEF is clear and colorless , looks exactly like water, it has
a slight smell of ammonia, similiar to some home cleaning agents.
DEF consists of deionized water in a 1:2 solution and is
contained in a reservoir separate from the fuel tank and is
metered into the engine's exhaust stream to control certain
emissions. Inside the exhaust pipe , the DEF vaporizes and
decomposes into ammonia and carbon dioxide .
RUNNING OUT OF DIESEL EXHAUST FUILD
Diesel exhaust fluid is used to reduce Nitrogen Oxigen
emissions (NOx). You will get a lot of warnings to refill the DEF
tank before you run out . If you decide to ignore the warnings to
refill the DEF tank before you run out, the engine is designed to
limit its power and fueling dramatically .

Indicator
Lamp
Drinking it must be voided at all costs. If that happens, contact a
doctor immediately.
WARNING
If it gets into your eyes, flush with large amounts of water immediately
for at least 15 minutes. Consult a doctor if you have any doubts or
symptoms that are concerning.
CAUTION
DEF residue can be easily cleaned up by washing the area with warm
water.
NOTICE
DEF fluid is corrosive to most metals used in automotive applications.
Carbon steels, iron, zinc, nickel, copper, aluminum and magnesium
are some of them. If it comes into contact with any metals, you should
clean the area with plenty of warm water to eliminate accelerated
corrosion.
NOTICE
The fluid typically has life of 18 months. It technically does not expire,
but it can lose its water content and the ratio of urea/water could
change.

DEF
Filler Cap
Urea is a compount of nitrogen that turns to ammonia when heated.
It is used in a variety of industries, including as a ferilizer in agriculture.
NOTICE
The DEF you purchase should state and display the certification
of the American Petroleum Institute (API), German Institute of
Standardization DIN 70700, the International Organization for
Standardization ISO 22241-1, and meet AUS-32 specifications. This
will ensure the proper purity and concentration (32.5%) of urea. For
more information of these specifications, visit www.iso.org
NOTICE
The 32.5% urea concentration is the ideal solution as it provides the
lowerst freeze point, for this reason it is critical.
WARNING
A 32.5% solution of DEF will begin to crystalize and freeze at 12
deg F (-11 deg C). At 32.5%, both the urea and water will freeze at
the same rate, ensuring that as it thaws, the fluid does not become
diluted, or over concentrated. The freezing and untawing of DEF will
not cause degradation of the product.
