Jack Warning Label

1. If equipped, remove the spare wheel and tools from storage.

2. Using the lug wrench, loosen, but do not remove, the lug nuts by turning them counter -
clockwise one turn while the wheel is still on
the ground.
3. When changing the front wheel, place the jack under the axle as close to the tire as possible.
Front Jacking Locations

When changing a rear wheel, securely place
the jack under the sway bar bracket (unless
both tires are flat on one side, then place jack
under shock bracket) facing forward in vehicle.

Rear Jacking Location
Before raising the wheel off the ground, make
sure that the jack will not damage surrounding
truck parts and adjust the jack position as re
-
quired.
4. Raise the vehicle until the wheel just clears the surface.
5. Remove the lug nuts and pull the wheel off. For Single Rear-Wheel (SRW) models, Install the
spare wheel and lug nuts with the cone shaped
end of the nuts toward the wheel. For Dual
Rear-Wheel (DRW) models, the lug nuts are a
two-piece assembly with a flat face. Lightly
tighten the nuts. To avoid risk of forcing the
vehicle off the jack, do not fully tighten the
nuts until the vehicle has been lowered.
6. Using the lug wrench, finish tightening the nuts using a crisscross pattern Ú page 397. If in
doubt about the correct tightness, have them
checked with a torque wrench by an
authorized dealer or at a service station.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the
Jacking Instructions for this vehicle.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off the
jack and hurt someone near it. Raise the vehicle
only enough to remove the tire.

322IN CASE OF EMERGENCY
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 trans -
mission in NEUTRAL, but do not increase the
engine idle speed while preventing 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.
GEAR SELECTOR OVERRIDE
6–SPEED TRANSMISSION
In order to move the vehicle in cases where the
transmission will not shift out of PARK (P) (such as
a depleted battery), a Manual Park Release is
available.

1. Turn the engine OFF.

2. Firmly apply the parking brake.
3. Tilt the steering wheel to the full up position.
4. Press and maintain firm pressure on the brake pedal.
5. Insert a screwdriver or similar tool into the access port (ringed circle) on the bottom of the
steering column, and push and hold the
override release lever up.

Gear Selector Override Access Port Location

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 cool -
ant bottle is hot.
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 immedi -
ately and call for service.

IN CASE OF EMERGENCY325
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are operable, disabled
vehicles may also be towed as described Ú page 185.
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 during prolonged efforts
to free a stuck vehicle.
When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, do not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may
result.
Revving the engine or spinning the wheels too fast may lead to transmission overheating and failure. It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).

SERVICING AND MAINTENANCE
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. This
means that service is required for your vehicle.
Operating conditions such as frequent short-trips,
trailer tow, extremely hot or cold ambient
temperatures will influence when the “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú
page 81.
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
12 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. 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. Rotate at the first sign
of irregular wear.
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and auto
-
matic transmission (6-speed only), and fill as
needed.
Check function of all interior and exterior lights.

OIL CHANGE INDICATOR SYSTEM —
D
IESEL ENGINE
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it
is time to change your engine oil by displaying the
words “Oil Change Due” in your instrument cluster
display. The engine oil change indicator system is
duty cycle based, which means the engine oil
change interval may fluctuate depending on your
personal driving style. Failure to change the engine
oil per the maintenance schedule can result in
internal engine damage.
An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú page 81.
Replace the engine oil and oil filter every
15,000 miles (24,000 km) or 12 months, or
sooner if prompted by the oil change indicator
system. Under no circumstances should oil change
intervals exceed 15,000 miles (24,000 km) or 12 months, whichever comes first.CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.

22_DPF_OM_EN_USC_t.book Page 332

SERVICING AND MAINTENANCE333
NOTE:
Under no circumstances should oil change inter -
vals exceed 15,000 miles (24,000 km) or
12 months or 500 hours, whichever comes first.
It is recommended that every 3,000 miles
(4,800 km), check the engine oil level at least
30 minutes after a fully warmed engine is shut
off. Checking the oil level while the vehicle is on
level ground will improve the accuracy of the oil
level reading. Add oil only when the level is at or
below the ADD or MIN mark.
Severe service (high ambient temperature,
short trips, heavy loading, trailer towing,
off-road, or law enforcement use) may reduce
oil change intervals. If models configured with optional B20 capability
are operated with greater than 5% levels of
biodiesel, the oil change interval must not exceed
12,500 miles (20,000 km) or 400 hours,
whichever comes first under any circumstances.
See the Fuel Requirements section for more
information regarding operation with biodiesel
blend (B6-B20) fuel meeting ASTM specification
D-7467.
PERFORM SERVICE INDICATOR —
