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.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of your
vehicle's emissions system and filters
harmful pollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
To avoid damaging the catalytic converter:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 486). •
Use the correct fuel.
See Fuel and
Refueling (page 255).
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Do not make any unauthorized
changes to your vehicle or engine. By law,
vehicle owners and anyone who
manufactures, repairs, or services a fleet of
vehicles are not permitted to intentionally
remove an emission control device or
prevent it from working.

FOUR-WHEEL DRIVE
PRECAUTIONS WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough
terrain without getting stuck or damaging
underbody components. The differences
that make your vehicle so versatile also
make it handle differently than an ordinary
passenger car. Always maintain steering
wheel control, especially in rough terrain.
Since sudden changes in terrain can result
in abrupt steering wheel motion, make sure
you grip the steering wheel from the outside. Do not grip the spokes. Drive
cautiously to avoid vehicle damage from
concealed objects such as rocks and
stumps. Drive slower in strong crosswinds
which can affect the normal steering
characteristics of your vehicle. Be
extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
Note:
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components.
FOUR-WHEEL DRIVE
LIMITATIONS
Operating Four-Wheel Drive with
a Spare or Mismatched Tires
(If
Equipped)
On four-wheel drive vehicles, the size of
the spare tire can affect the four-wheel
drive system. If there is a significant
difference between the size of the spare
tire and the remaining tires, you could have
limited four-wheel drive functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, we
recommend that you do not:
• Exceed
50 mph (80 km/h) with a
four-wheel drive mode turned on.
• Turn on a four-wheel drive mode
unless the vehicle is stationary.
• Use a four-wheel drive mode on dry
pavement.
Driving with the full-size dissimilar spare
wheel and tire assembly can limit
four-wheel drive functionality, especially
when driving in a mechanically locked
four-wheel drive mode. You can experience
