JACKING AND TIRE CHANGING
WARNING!
• Do not attempt to change a tire on theside of the vehicle close to moving traf-
fic. Pull far enough off the road to avoid
the danger of being hit when operating
the jack or changing the wheel.
• Being under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the
jack and fall on you. You could be
crushed. Never put any part of your body
under a vehicle that is on a jack. If you
need to get under a raised vehicle, take
it to a service center where it can be
raised on a lift.
• Never start or run the engine while the
vehicle is on a jack.
• The jack is designed to be used as a tool
for changing tires only. The jack should
not be used to lift the vehicle for service
purposes. The vehicle should be jacked
on a firm level surface only. Avoid ice or
slippery areas.
Jack Location
The jack and jack tools are stored under the
front passenger seat.
To release the jack kit for it’s storage location,
you must push down and turn the lock knob
1/4 turn counter clockwise to the unlock
position.
CAUTION!
Do not force lock knob over limit. Damage
to lock knob may occur.

Jacking Instructions
WARNING!
Carefully follow these tire changing warn-
ings to help prevent personal injury or
damage to your vehicle:
• Always park on a firm, level surface asfar from the edge of the roadway as
possible before raising the vehicle.
WARNING!
• Turn on the Hazard Warning flashers.
• Block the wheel diagonally opposite thewheel to be raised.
• Set the parking brake firmly and set an
automatic transmission in PARK; a
manual transmission in REVERSE.
• Never start or run the engine with the
vehicle on a jack.
• Do not let anyone sit in the vehicle when
it is on a jack.
• Do not get under the vehicle when it is
on a jack. If you need to get under a
raised vehicle, take it to a service center
where it can be raised on a lift.
• Only use the jack in the positions indi-
cated and for lifting this vehicle during a
tire change.
• If working on or near a roadway, be
extremely careful of motor traffic.
• To assure that spare tires, flat or in-
flated, are securely stowed, spares must
be stowed with the valve stem facing the
ground.
CAUTION!
Do not attempt to raise the vehicle by
jacking on locations other than those indi-
cated in the Jacking Instructions for this
vehicle.

WARNING!
Do not attempt jump starting if the battery
is frozen. It could rupture or explode and
cause personal injury.
CAUTION!
Do not use a portable battery booster pack
or any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
Preparations For Jump Start
The vehicle’s jump starting remote posts are
located under the hood, in the engine com-
partment on the driver's side.The Remote Positive(+)Post is covered with
a protective cap located on the side of the
Front Power Distribution Center. The Remote Negative
(-)Post is located on
the core support closest to the front of the
vehicle.
WARNING!
• Take care to avoid the radiator cooling fan whenever the hood is raised. It can
start anytime the ignition switch is ON.
You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
• Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
1. Apply the parking brake, shift the auto- matic transmission into PARK and turn
the ignition to the OFF position.
2. Turn off the heater, radio, and all unnec- essary electrical accessories.

3. If using another vehicle to jump start thebattery, park the vehicle within the jumper
cables reach, apply the parking brake and
make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground connec-
tion and personal injury could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump starting proce-
dure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged ve-
hicle.
Connecting The Jumper Cables
1. Connect the positive (+)end of the jumper
cable to the remote positive (+)post of the
discharged vehicle.
NOTE:
The remote positive (+)post is located in
the engine compartment on the driver's
side under the cover of the Front Power
Distribution Center.
2. Connect the opposite end of the positive (+) jumper cable to the positive (+)post of
the booster battery.
3. Connect the negative end (-)of the jumper
cable to the negative (-)post of the
booster battery.
4. Connect the opposite end of the negative (-)jumper cable to the remote negative (-)
post of the discharged vehicle.
NOTE:
The remote negative (-)post is located in
the front of the engine compartment on
the driver's side.WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause
the battery to explode and could result in
personal injury. Only use the specific
ground point, do not use any other exposed
metal parts.
5. Start the engine in the vehicle that has the booster battery. Let the engine idle a few
minutes and then start the engine in the
vehicle with the discharged battery.
6. Once the engine is started, disconnect the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative end (-)of the
jumper cable from the remote negative (-)
post of the vehicle with the discharged
battery.
2. Disconnect the opposite end of the nega- tive (-)jumper cable from the negative (-)
post of the booster battery.
117

3. Disconnect the positive end(+)of the
jumper cable from the positive (+)post of
the booster battery.
4. Disconnect the opposite end of the posi- tive (+)jumper cable from the remote
positive (+)post of the discharged
vehicle.
5. Close the cover of the Front Power Distri- bution Center.
If frequent jump starting is required to start
your vehicle you should have the battery and
charging system inspected at your authorized
dealer.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
Battery Location
There are two remote jump starting posts
under the hood which is the recommended
jump start location. If access to the battery is
needed, an access panel on the driver’s side
floor will allow for battery access.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat. • You can also turn the temperature control
to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
IN CASE OF EMERGENCY
118

CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop
the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer
drops back into the normal range. If the
pointer remains on HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.
GEAR SELECTOR OVERRIDE (GASOLINE
ENGINE ONLY)
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position,
you can use the following procedure to tem-
porarily move the gear selector:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
3. Using a small screwdriver or similar tool,remove the gear selector override access
cover which is located below the gear
selector. 4. Press and maintain firm pressure on the
brake pedal.
5. Insert the screwdriver or similar tool into the access port, and push and hold the
override release lever forward.
6. Move the gear selector to the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
8. Reinstall the gear selector override access cover.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand,
or snow, it can often be moved using a rock-
ing motion. Turn the steering wheel right and
left to clear the area around the front wheels.
Shift back and forth between DRIVE and
REVERSE, while gently pressing the accel-
erator. Use the least amount of accelerator
pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing
the engine. NOTE:
Vehicles with diesel engine (automated
manual transmission) cannot be rocked in
this manner, because the transmission will
not allow shifts between forward and RE-
VERSE gears while the wheels are turning.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating and
failure. Allow the engine to idle with the
transmission in NEUTRAL for at least one
minute after every five rocking-motion
cycles. This will minimize overheating and
reduce the risk of transmission failure dur-
ing prolonged efforts to free a stuck ve-
hicle.

Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
device to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN mode.NOTE:
For vehicles equipped with diesel engine and
electric park brake, see important informa-
tion under “Automated Manual Transmis-
sion.”
If the key fob is unavailable or the vehicle's
battery is discharged, refer to “Gear Selector
Override” in this section for instructions on
shifting the automatic transmission out of
PARK for towing.CAUTION!
• Do not use sling type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flat bed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.

SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate in
the instrument cluster. This means that ser-
vice is required for your vehicle. Operating
conditions such as frequent short-trips,
trailer tow, and extremely hot or cold ambient
temperatures will influence when the “Oil
Change Required” message is displayed. Se-
vere Operating Conditions can cause the
change oil message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If a scheduled oil change is
performed by someone other than your autho-
rized dealer, the message can be reset byreferring to the steps described under “Instru-
ment Cluster Display” in “Getting To Know
Your Instrument Panel” in your Owner’s
Manual on
www.ramtrucks.com/en/owners/
manuals for further information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
twelve months or 350 hours of engine run
time, whichever comes first. The 350 hours
of engine run or idle time is generally only a
concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles
(6,500 km) or 350 hours of engine run time
if the vehicle is operated in a dusty and off
road environment or is operated predomi-
nately at idle or only very low engine RPM’s.
This type of vehicle use is considered Severe
Duty. Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look
for unusual wear or damage
• Check the fluid levels of the coolant reser- voir, brake master cylinder, and power
steering and fill as needed
• Check function of all interior and exterior lights
