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 under “Recreational Tow-
ing” 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" in
"Starting And Operating" for more informa-
tion. If the vehicle cannot be placed in Trans-
port mode (for example, engine will not run),
tie-downs must be fastened to the axles (not
to the body). Failure to follow these instruc-
tions may cause fault codes to be set and/or
cause loss of proper tie-down tension.

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 fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel
usage will influence when the “Oil Change
Required” message is displayed. Severe Op-
erating 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 scheduled oil change. If a scheduled oil
change is performed by someone other than
your authorized dealer, the message can be
reset by referring to the steps described un-
der “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel”.
1500 Models Only
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.
2500 – 3500 Models Only
NOTE:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 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
NOTE:
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-
nantly 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 tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Check the fluid levels of the coolant reser- voir, brake master cylinder, power steering
(2500/3500 Models Only) and automatic
transmission (six-speed only) and fill as
needed
• Check function of all interior and exterior lights
