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.
SELECTIVE CATALYTIC
REDUCTION SYSTEM
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.

(If Equipped)

•
Avoid spilling diesel exhaust fluid on
painted surfaces, carpeting or plastic
components. Immediately wipe away
any diesel exhaust fluid that has spilled
with a damp cloth and water. If it has
already crystallized, use warm water
and a sponge.
• Do not store the diesel exhaust fluid
bottle in your vehicle. If it leaks it could
cause damage to interior components
or release an ammonia odor inside your
vehicle.
• Do not re-use the diesel exhaust fluid
container once it is emptied.
• Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23–68°F (-5– 20°C).
• The system has a diesel exhaust fluid
quality sensor. Dilution of diesel
exhaust fluid or use of any other liquid
in the selective catalytic reduction
system leads to a diesel exhaust fluid
system fault, eventually leading to the
vehicle only operating in idle-only
mode.
• Do not dilute diesel exhaust fluid with
water or any other liquid. FILLING THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM TANK
FILLING THE SELECTIVE
CATALYTIC REDUCTION SYSTEM
TANK IN COLD WEATHER
Diesel exhaust fluid may freeze if the
ambient temperature is below 12°F (-11°C).
Your vehicle has a preheating system
which allows diesel exhaust fluid to
operate below
12°F (-11°C). If you do not
use your vehicle for an extended period
when the ambient temperature is below
12°F (-11°C)
, the fluid in the tank may
freeze. If the tank is overfilled and the fluid
freezes it may cause damage that your
Warranty will not cover.
FILLING THE SELECTIVE
CATALYTIC REDUCTION SYSTEM
TANK USING A FUEL STATION
PUMP
Filling the diesel exhaust fluid tank using
a fuel station pump is similar to refueling
your vehicle.
1. Fully open the fuel filler door. 2. Remove the diesel exhaust fluid tank
filler cap.

HOW DOES FOUR-WHEEL
DRIVE WORK - RAPTOR
The 2-speed automatic four-wheel drive
system utilizes an electronically controlled
on-demand 2-speed transfer case. This
system monitors various vehicle sensory
inputs to provide an increased level of
performance. This system offers the driver
two-wheel drive high, four-wheel drive
auto, four-wheel drive high, and four-wheel
drive low as available modes of operation.
When four-wheel drive auto is selected,
the system continuously varies power to
the front wheels for optimum performance
for all on-road conditions. When either
four-wheel drive high or four-wheel drive
low are selected, the system provides
mechanically locked power to the front
and rear wheels for use in off-road or
slippery conditions such as deep snow,
sand or mud. Selecting four-wheel drive
low also provides additional gearing for
increased torque multiplication for
conditions like deep sand, steep slopes, or
pulling heavy objects. Additionally, the
system is capable of recreational flat
towing by putting the transfer case into
neutral (N). See Recreationally Towing
Your Vehicle (page 490).
