If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while cranking the engine. This should clear any
excess fuel in case the engine is flooded.
CAUTION!To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again. WARNING!• Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
• Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission 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 Emergen-
cies” for further information.264 STARTING AND OPERATING

To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builders Guide for information
on stowing your spare tire (if equipped).
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
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.
NOTE: When using a portable battery booster pack
follow the manufacturer ’s operating instructions and
precautions.366 WHAT TO DO IN EMERGENCIES

WARNING!• Take care to avoid the radiator cooling fan when-
ever 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 watch bands or
bracelets that might 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. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories. 3. If using another vehicle to jump-start the battery, park
the vehicle within the jumper cables reach, set 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 connection and personal
injury could result.
Jump-Starting Procedure
WARNING!Failure to follow this procedure could result in per-
sonal injury or property damage due to battery ex-
plosion.368 WHAT TO DO IN EMERGENCIES

CAUTION!Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
1. Connect the positive (+) end of the jumper cable to the
positive (+) post of the discharged vehicle.
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 a good engine ground (exposed metal part of the
discharged vehicle’s engine) away from the battery and
the fuel injection system. WARNING!Do not connect the 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.
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.
Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative (-) jumper cable from the
engine ground of the vehicle with the discharged battery.
7. Disconnect the negative end (-) of the jumper cable
from the negative (-) post of the booster battery.

8. Disconnect the opposite end of the positive (+) jumper
cable from the positive (+) post of the booster battery.
9. Disconnect the positive (+) end of the jumper cable
from the positive (+) post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting. 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 shift lever
rhythmically between DRIVE and REVERSE while ap-
plying slight pressure to the accelerator.
CAUTION!• Racing the engine or spinning the wheels may
lead to transmission overheating and failure. Al-
low the engine to idle with the shift lever in
NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize over-
heating and reduce the risk of transmission failure
during prolonged efforts to free a stuck vehicle.
