2008 DODGE RAM 3500 GAS automatic transmission

CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into PARK with the transfer case in
NEUTRAL and the engine running. With the transfer
case in NEUTRAL ensure, that the engine is OFF
prior to shifting the transmission into PARK.
Returning to Normal Operation Ð Electronic Shift
Transfer Case
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring vehicle to a complete stop.
2. Shut OFF the engine.
3. Turn the ignition key to the ON position, but do not
start the engine.4. Depress the brake pedal.
5. Shift automatic transmission to NEUTRAL or depress
clutch on manual transmission.
6. Using the point of a ballpoint pen or similar object,
depress the recessed transfer case Neutral (N) button for
one second.
7. After the Neutral indicator light turns off, release the
Neutral (N) button.
8. After the Neutral (N) button has been released, the
transfer case will shift to the position identified by the
selector switch.
9. Shift automatic transmission into PARK.
NOTE:The transfer case cannot be shifted into NEU-
TRAL from the 4AUTO (if equipped) position.

Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to an authorized
service center where it can be raised on a lift.
Do not raise this vehicle using a bumper jack. The jack is
designed as a tool for changing tires on this vehicle only.
It is not recommended that the jack be used for service
purposes or to lift more than one wheel at a time.
Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission) or REVERSE
(manual transmission). On four-wheel drive vehicles,
shift the transfer case to the 4L position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
²Turn on the Hazard Warning Flasher.

²Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if the right front
wheel is being changed, block
the left rear wheel.
²Passengers should not remain in the vehicle when the
vehicle is being jacked.
Instructions
WARNING!
Carefully follow these tire changing warnings to help prevent
personal injury or damage to your vehicle:
²Always park on a firm, level surface as far from the edge of the
roadway as possible before raising the vehicle.
²Block the wheel diagonally opposite the wheel to be raised.
²Set the parking brake firmly and set an automatic transmis-
sion in park; a manual transmission in reverse.
²Never start or run the engine with the vehicle on a jack.
²Do not let anyone sit in the vehicle when it is on a jack.
²Do not get under the vehicle when it is on a jack.
²Only use the jack in the positions indicated and for lifting this
vehicle during a tire change.
²If working on or near a roadway, be extremely careful of motor
traffic.
²To assure that spare tires, flat or inflated are securely stowed,
spares must be stowed with the valve stem facing the ground.
²Turn on the Hazard warning flasher.

424 WHAT TO DO IN EMERGENCIES

HOISTING
A conventional floor jack may be used at the jacking
locations. Refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts or the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING PROCEDURES
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic transmis-
sion cannot be started this way. Pushing or towing a
vehicle equipped with a manual transmission may over-
heat and damage the catalytic converter. Also, there is a
greater risk of an accident when a vehicle is being pushed
or towed. 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, so follow this
procedure carefully.
434 WHAT TO DO IN EMERGENCIES

WARNING!
Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin or clothing. Don't
lean over battery when attaching clamps or allow the
clamps to touch each other. If acid splashes in eyes or
on skin, flush contaminated area immediately with
large quantities of water.
A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away from
the vent holes.
Do not use a booster battery or any other booster
source that has a greater than 12-volt system, i.e., do
not use a 24-volt power source.
1. Remove all metal jewelry such as watch bands or
bracelets which might make an unintended electrical
contact.2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake on
both vehicles, place the automatic transmission in PARK
or the manual transmission in NEUTRAL, and turn the
ignition OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.

7. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
FREEING A STUCK VEHICLE
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the gear
selector rhythmically between DRIVE and REVERSE
(automatic transmissions) or between 1st and REVERSE
(manual transmissions), while applying slight pressure to
the accelerator.
In general, the least amount of accelerator pedal pressure
to maintain the rocking motion without spinning the
wheels or racing the engine, is most effective. Racing the
engine or spinning the wheels, due to the frustration of
not freeing the vehicle, may lead to transmission over-
heating and failure. Allow the engine to idle with the
transmission selector in NEUTRAL for at least one
minute after every five rocking-motion cycles. This will
minimize overheating and reduce the risk of transmis-
sion failure during prolonged efforts to free a stuck
vehicle.

TOWING A DISABLED VEHICLE
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for the purpose, following equip-
ment manufacturer's instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing device to
the main structural members of the vehicleÐnot to
bumpers or associated brackets. State and local laws
applying to vehicles under tow must be observed.
4-Wheel Drive Vehicles
CAUTION!
To avoid damage to the transfer case while towing,
always use one of the following methods.NOTE:The transfer case must be in the neutral position,
and the transmission must be in PARK (automatic trans-
mission), or in gear (manual transmission) to tow a 4WD
vehicle with one end of the vehicle raised.
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of vehicle raised and
the opposite end on a towing dolly.
2±Wheel Drive Vehicles
Provided that the transmission is operable, tow with the
transmission in NEUTRAL and the ignition key in the
OFF position along with the front wheels raised and the
rear wheels on the ground. Speed must not exceed 30
mph (50 km/h) and distance must not exceed 15 mi (25
km).
