Selective Catalytic Reduction System

WHAT IS THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM
The selective catalytic reduction system
helps reduce emission levels of oxides of
nitrogen from the exhaust system.
HOW DOES THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM WORK
The selective catalytic reduction system
injects diesel exhaust fluid into the exhaust
system to enable correct selective catalytic
reduction system function.

PRECAUTIONS
WARNING: Keep diesel exhaust
fluid out of reach of children. Avoid
contact with skin, eyes or clothing. In
case of contact with your eyes, flush
immediately with water and get prompt
medical attention. In case of contact
with your skin, clean immediately with
soap and water. If you swallow any
diesel exhaust fluid, drink plenty of
water, call a physician immediately.

WARNING: Only refill the diesel
exhaust fluid tank in a well ventilated
area. When you remove the diesel
exhaust fluid tank filler cap or a diesel
exhaust fluid container cap, ammonia
vapors may escape. Ammonia vapors
can be irritating to skin, eyes and mucous
membranes. Inhaling ammonia vapors
can cause burning to the eyes, throat and
nose and cause coughing and watery
eyes.
WARNING: Diesel exhaust fluid
must be refilled when low or replaced
when contaminated or your vehicle
speed becomes limited to 50 mph
(80 km/h). In these conditions, drive with
caution and refill diesel exhaust fluid
immediately. If the diesel exhaust fluid
becomes empty or contaminated and
fluid is not replaced, your vehicle
becomes limited to engine idle only once
stopped. In these conditions, be cautious
where you stop your vehicle because you
may not be able to drive long distances
or maintain highway speeds until you
refill or replace the diesel exhaust fluid.
WARNING: Tampering with or
disabling the selective catalytic
reduction system results in severe
vehicle performance limitation including
eventual speed limiting to 5 mph
(8 km/h).
Note: Do not put diesel exhaust fluid in the
fuel tank. This can cause damage that your
vehicle Warranty may not cover.
Selective catalytic reduction systems are
sensitive to contamination of the diesel
exhaust fluid. Maintaining the purity of the
fluid is important to avoid system
malfunctions. If you remove or drain the
diesel exhaust fluid tank, do not use the
same fluid to refill the tank. The system
has a sensor to monitor fluid quality.
