4. Attach the hook to the center tether strap loop (seediagram). Tighten the tether strap according to the child
seat manufacturer ’s instructions.
NOTE: If there are child seats in both of the outboard (left
and right) seating positions, the tether strap hooks of both
child seats should be connected to the center tether strap
loop. This is the correct way to tether two outboard child
seats. Center Seat:
1. Raise the head restraint and reach between the rear seat
and rear glass to access the tether strap loop.
2. Place a child restraint on the seat and adjust the tether strap so that it will reach over the seat back, under the
head restraint, through the tether strap loop behind the
seat and over to the tether strap loop behind either the
right or left outboard seat.

Installing Three Child Restraints:
1. Place a child restraint on each outboard rear seat. Routethe tether straps following the directions for right and
left seating positions, above.
2. Attach both hooks to the center tether strap loop, but do not tighten the straps yet.
3. Place a child restraint on the center rear seat. Route the tether strap following the directions for the center
seating position, above.
4. Attach the hook to the outboard tether strap loop.
5. Tighten the tether straps according to the child seat manufacturer ’s instructions, tightening the right and
left tether straps before the center tether strap.
WARNING!
•An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchorage position directly be-
hind the child seat to secure a child restraint top
tether strap.
• If your vehicle is equipped with a split rear seat,
make sure the tether strap does not slip into the
opening between the seatbacks as you remove slack
in the strap.

WARNING!
A loose head restraint thrown forward in a collision or
hard stop could cause serious injury or death to occu-
pants of the vehicle. Always securely stow removed
head restraints in a location outside the occupant
compartment.NOTE:
•
The rear center head restraint (Crew Cab and Quad Cab)
has only one adjustment position that is used to aid in
the routing of a tether. Refer to “Occupant Restraints” in
“Things to Know Before Starting Your Vehicle” for
further information.
• Do not reposition the head restraint 180 degrees to the
incorrect position in an attempt to gain additional clear-
ance to the back of the head.
WARNING!
ALL the head restraints MUST be reinstalled in the
vehicle to properly protect the occupants. Follow the
re-installation instructions above prior to operating the
vehicle or occupying a seat.

WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
• If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery
or the battery in another vehicle. This type of start
can be dangerous if done improperly. Refer to
“Jump-Starting” in “What To Do In Emergencies” for
further information.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the ignition
button/key is released. If this occurs, continue cranking
with the accelerator pedal pushed all the way to the floor.
Release the accelerator pedal and the ignition button/key
once the engine is running smoothly.
If the engine shows no sign of starting after a 10 second
period of engine cranking with the accelerator pedal held
to the floor, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
1500 Models
The engine block heater cord is routed under the hood on
the passenger side of the vehicle near the right head lamp
assembly. It is located between the front grill and the
radiator, but underneath the black upper seal.
2500/3500 Models
The engine block heater cord is routed through the grille by
the right front tow hook.
It includes a removable cap that is secured by a tethered
strap. It also has a c-clip that is used for storage when not
in use for the winter months. During winter months,
remove the heater cord wiring assembly from itself on the
c-clip.

ADDING FUEL
The fuel filler cap (gas cap) is located behind the fuel filler
door, on the left side of the vehicle. Open the fuel door and
remove the fuel cap by turning it counter-clockwise.
NOTE:When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap.
• A poorly fitting fuel filler cap could let impurities
into the fuel system.
• A poorly fitting fuel filler cap may cause the “Mal-
function Indicator Light (MIL)” to turn on.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel nozzle
“clicks” or shuts off, the fuel tank is full.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel to the vehicle when the engine is
running.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.

4. While holding the locking tab in the disengaged posi-tion, pull the tether strap to rotate the lever rearward,
until it locks in place pointing towards the driver’s seat.
Release the locking tab and verify that the Manual Park
Release lever is locked in the released position.
5. The vehicle is now out of PARK and can be towed. Release the parking brake only when the vehicle is
securely connected to a tow vehicle.
To Reset The Manual Park Release:
1. Push the locking tab to the right, to unlock the lever.
2. Rotate the Manual Park Release lever forward to its original position, until the locking tab snaps into place
to secure the lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Re-install the access cover.TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the transmis-
sion and drivetrain are operable, disabled vehicles may
also be towed as described under “Recreational Towing” in
the “Starting And Operating” section.
NOTE: Vehicles equipped with air suspension must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to Air
Suspension inStarting And Operating for more informa-
tion. If the vehicle cannot be placed in Transport mode (for
example, engine will not run), tie-downs must be fastened
to the axles (not to the body). Failure to follow these
instructions may cause fault codes to be set and/or cause
loss of proper tie-down tension.
