Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only use
a floor mat that does not interfere with the operation of the
accelerator, brake or clutch pedals. Only use a floor mat that
is securely attached using the floor mat fasteners so it cannot
slip out of position and interfere with the accelerator, brake
or clutch pedals or impair safe operation of your vehicle in
other ways.
WARNING!
An improperly attached, damaged, folded, or stacked
floor mat, or damaged floor mat fasteners may cause
your floor mat to interfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
• ALWAYS securely attach your floor mat using the floor mat fasteners. DO NOT install your floor mat
upside down or turn your floor mat over. Lightly pull to
confirm mat is secured using the floor mat fasteners on
a regular basis.
• ALWAYS REMOVE THE EXISTING FLOOR MAT
FROM THE VEHICLE before installing any other
floor mat. NEVER install or stack an additional floor
mat on top of an existing floor mat.
• ONLY install floor mats designed to fit your vehicle. NEVER install a floor mat that cannot be properly
attached and secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA approved floor
mat for the specific make, model, and year of your
vehicle.
• ONLY use the driver’s side floor mat on the driver’s side floor area. To check for interference, with the
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch pedal
(if present) to check for interference. If your floor mat
interferes with the operation of any pedal, or is not
secure to the floor, remove the floor mat from the
vehicle and place the floor mat in your trunk.
• ONLY use the passenger’s side floor mat on the passenger’s side floor area.
WARNING! (Continued)

STARTING AND OPERATING 331
the brakes are required to control vehicle speed, apply
them lightly and avoid locking or skidding the tires.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible and only be
attempted when necessary, in a safe responsible manner.
You should only drive through areas which are designated
and approved. You should tread lightly and avoid damage
to the environment. You should know your vehicle's abilities
and be able to recover it if something goes wrong. You
should never stop or shut a vehicle off when crossing deep
water unless you ingested water into the engine air intake. If
the engine stalls do not attempt to restart it. Determine if it
has ingested water first. The key to any crossing is low andslow. You want to use first gear in 4L (Low Range) and
proceed very slowly with a constant slow speed (3-5 mph
[5–8 km/h] maximum) and light throttle. Keep the vehicle
moving; do not try to accelerate through the crossing. After
crossing any water higher than the bottom of the axle differ
-
entials, you should inspect all of the vehicle fluids for signs
of water ingestion.
• Before You Cross Any Type Of Water – As you approach
any type of water you need to determine if you can cross it
safely and responsibly. If necessary, get out and walk
through the water or probe it with a stick. You need to be
sure of its depth, approach angle, current and bottom
condition. Be careful of murky or muddy waters, check for
hidden obstacles. Make sure you will not be intruding on
any wildlife and you can recover the vehicle if necessary.
The key to a safe crossing is the water depth, current and
bottom conditions. On soft bottoms the vehicle will sink in,
WARNING!
If the engine stalls or you lose headway or cannot make
it to the top of a steep hill or grade, never attempt to turn
around. To do so may result in tipping and rolling the
vehicle, which may result in severe injury. Always back
carefully straight down a hill in REVERSE. Never back
down a hill in NEUTRAL using only the vehicle brakes.
Never drive diagonally across a hill, always drive
straight up or down.
CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive too
fast or through too deep of water. Water can cause
permanent damage to engine, driveline or other vehicle
components and your brakes will be less effective once
wet and/or muddy.

STARTING AND OPERATING 427
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air Suspen-
sion System” in “Starting And Operating” for further infor -
mation.
NOTE:
The vehicle must remain in the engine running position
while attaching a trailer for proper leveling of the air suspen -
sion system.
SNOWPLOW
2500/3500 Models Only
Snowplow Prep Packages are available as a factory installed
option. These packages include components necessary to
equip your vehicle with a snowplow.
NOTE:
Before installation of a snowplow it is highly recommended
that the owner/installer obtain and follow the recommenda -
tions contained within the current Body Builders Guide. See
your authorized dealer, installer or snowplow manufacturer
for this information. There are unique electrical systems that
must be connected to properly assure operator safety and
prevent overloading vehicle systems. Before Plowing
• Check the hydraulic system for leaks and proper fluid
level.
• Check the mounting bolts and nuts for proper tightness.
• Check the runners and cutting edge for excessive wear. The cutting edge should be ¼ to ½ in (6 cm to 1.2 cm) above
ground in snow plowing position.
• Check that snowplow lighting is connected and func -
tioning properly.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision. Do
not expect that the airbag will perform as described
earlier in this manual.
CAUTION!
The “Lamp Out” indicator could illuminate if exterior
lamps are not properly installed.

After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.Four And Five Lug Nuts/Bolts Torque PatternFUEL REQUIREMENTS
6.4L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15%
in this engine. This engines is designed to meet all emissions regu -
lations and provide satisfactory fuel economy and
performance when using high quality unleaded
gasoline having a posted octane number range of 87 to 89 as
specified by the (R+M)/2 method. The use of 89 octane
“Plus” gasoline is recommended for optimum performance
and fuel economy.
While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a cause
for concern. However, if the engine is heard making a heavy
knocking sound, see your dealer immediately. Use of gaso -
line with an octane number lower than 87 can cause engine
failure and may void or not be covered by the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before considering
service for the vehicle.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.8
