Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, you can use the
Paddle Shift switches or manual gate of shifter to manu-
ally select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions, will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking.
Paddle Shift Mode
• When using the Paddle Shift switches, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or
“3” if needed to maintain the desired speed.
• To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.
Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

System Overview
This vehicle is equipped with a Diesel Exhaust Fluid
(DEF) injection system and a Selective Catalytic Reduc-
tion (SCR) catalyst to meet the emission requirements.
The DEF injection system consists of the following com-
ponents:
•DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst
The DEF injection system and SCR catalyst enable the
achievement of diesel emissions requirements; while main-
taining outstanding fuel economy, drivability, torque and
power ratings.
Refer to “Driver Information Display (DID)” in “Under-
standing Your Instrument Panel” for system messages
and warnings.
NOTE:
•
Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise
from under the vehicle at a stop. This is normal opera-
tion.
• The DEF pump will run for a period of time after
engine shutdown to purge the DEF system. This is
normal operation and may be audible from the rear of
the vehicle.

ADDING FUEL
1. Press the fuel filler door release switch (located underthe headlamp switch).
2. Open the fuel filler door.

2 — Diesel Exhaust Fluid Fill Location
NOTE: There is no fuel filler cap. A flapper door inside
the filler pipe seals the system.

3. Insert the fuel nozzle fully into the filler pipe – thenozzle opens and holds the flapper door while refuel-
ing.
4. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off the fuel tank is full.
5. Remove the fuel nozzle and close the fuel door.
Emergency Fuel Can Refueling
Most fuel cans will not open the flapper door.
A funnel is provided to open the flapper door to allow
emergency refueling with a fuel can.
1. Retrieve funnel from the spare tire kit. 2. Insert funnel into same filler pipe opening as the fuel
nozzle.

STARTING AND OPERATING 63

NOTE:Ensure funnel is inserted fully to hold flapper
door open.
3. Pour fuel into funnel opening.
4. Remove funnel from filler pipe, clean off prior to putting back in the spare tire kit.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the “Malfunction Indicator
Light” to turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the
ground while filling.
Emergency Fuel Fill Location
64 STARTING AND OPERATING

Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” These
microbes form “slime” that will clog the fuel filtration
system and lines. Drain condensation from the supply
tank and change the line filter on a regular basis.
NOTE:When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system. If the vehicle will not start, refer to “Maintenance
Procedures/Priming If The Engine Has Run Out Of Fuel”
in “Maintaining Your Vehicle” for further information.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in tempera-
tures between 10° and 90°F (-12° and 32°C), it will last a
minimum of one year.
4
STARTING AND OPERATING 65

DEF is subject to freezing at the lowest temperatures.
For example, DEF may freeze at temperatures at or below
12° F (-11° C). The system has been designed to operate in
this environment.
NOTE:When working with DEF, it is important to know
that:
• Any containers or parts that come into contact with
DEF must be DEF compatible (plastic or stainless
steel). Copper, brass, aluminum, iron or non-stainless
steel should be avoided as they are subject to corrosion
by DEF.
• If DEF is spilled, it should be wiped up completely.Adding Diesel Exhaust Fluid
The DEF gauge (located on the Driver Information Dis-
play (DID display) will display the level of DEF remain-
ing in the tank. Refer to “Driver Information Display
(DID)” in “Understanding Your Instrument Panel” for
further information.
NOTE: Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used in your
vehicle.
DEF Fill Procedure
NOTE: Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for the correct fluid type.
1. Remove cap from DEF fill inlet (located in fuel door).

2 — Diesel Exhaust Fluid Fill Location
2. Insert DEF fill adapter/nozzle into DEF fill inlet. NOTE:
•The DEF gauge may take up to five seconds to
update after adding a gallon or more of Diesel
Exhaust Fluid (DEF) to the DEF tank. If you have a
fault related to the DEF system, the gauge may not
update to the new level. See your authorized dealer
for service.
• The DEF gauge may also not immediately update
after a refill if the temperature of the DEF fluid is
below 12F (-11C). The DEF line heater will possibly
warm up the DEF fluid and allow the gauge to
update after a period of run time. Under very cold
conditions, it is possible that the gauge may not
reflect the new fill level for several drives.
