•The“D”range can be selected when towing. However,
if frequent shifting occurs while in this range, the“3”
range must be selected.
NOTE:Using the“3”range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up.
WARNING!
Connecting trailer brakes to your vehicle’s hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
•Do not attempt to tow a trailer while using a compact
spare tire, except for emergency use only. Do not
exceed 50 mph (80km/h), and repair the damaged tire
immediately.
•When towing a trailer greater than 2000 lbs. (907 kg)
you should carry a full-size wheel and tire as a spare in
the event of a flat. If the compact spare tire is used it
may adversely affect vehicle handling.
•Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
recommended for motoring safety.
•The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more
than 45 minutes of continuous operation. See Schedule
“B”in section 8 of this manual for transmission fluid
change intervals.
NOTE:
•
For vehicles equipped with Autostick. By using the
Autostick modes, and selecting a specific gear range,
frequent shifting can be avoided. The highest gear
range should be selected that allows for adequate
performance. For example, choose“4”if the desired
speed can be maintained. Choose“3”or“2”if needed
to maintain the desired speed.

•Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Connecting trailer brakes to your vehicle’s hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
254 STARTING AND OPERATING
Page 283 of 368
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
CAUTION!
Operating the engine with the oil levels below the
safe zone, or operating with oil levels that exceed the
top of the safe zone by 25% may cause engine
damage.
Change Engine Oil
Road conditions and your kind of driving affects the
interval at which your oil should be changed. Check the
following list to see if any apply to you.
•Day or night temperatures are below 32°F(0°C).
•Stop and Go driving.
•Extensive engine idling.
•Driving in dusty conditions.
•Short trips of less than 10 miles (16 km).
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C).
•Trailer towing.

CAUTION!
The fluid level is preset at the factory and does not
require adjustment under normal operating condi-
tions. If a transmission fluid leak occurs, visit your
authorized dealer immediately. Severe damage to the
transmission may occur. Your authorized dealer has
the proper tools to accurately adjust the fluid level.
Fluid and Filter Changes
Automatic transmission fluid and filter should be
changed as follows:
Maintenance schedule“A”—No change necessary.
Maintenance schedule“B”–Every 60,000 miles (96 000
km) change fluid and filter under the following condi-
tions:
•Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle is drivenregularlyfor
more than 45 minutes of continuous operation.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
All Wheel Drive (AWD)—If Equipped
The all wheel drive system consists of a Transfer Case,
and Front Differential. The exterior surface of these
components should be inspected for evidence of fluid
leaks. Confirmed leaks should be repaired as soon as
possible.
The transfer case fill plug is located on the rear housing
near the output shaft. The level can be verified by the
service plug in the middle of the rear housing, even with
the bottom of the hole. The front differential drain plug is
on the outer cover near the halfshaft attachment. This
unit can only be filled by removing the halfshaft and
filling through that opening.
Fluid Changes
The fluid should be changed as follows:
Normal UsageNo Service Required
Severe Usage
Front Differential 48,000 miles (77 000 km)
Transfer Case 48,000 miles (77 000 km)
302 MAINTAINING YOUR VEHICLE
Page 303 of 368

Severe Usage is defined as:
1. More than 50% of vehicle operation in stop and go
traffic where vehicle is driven regularly for more than 45
minutes of continuous operation, such as in heavy city or
in construction zone traffic,
2. Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle driven regularly for
more than 45 minutes of continuous operation.
Front And Rear Wheel Bearings
Front and rear wheel bearings are permanently sealed.
No regular maintenance is required for these compo-
nents.
Appearance Care and Protection from Corrosion
Protection of Body and Paint from Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extremehot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
•Road salt, dirt and moisture accumulation.
•Stone and gravel impact.
•Insects, tree sap and tar.
•Salt in the air near seacoast localities.
•Atmospheric fallout/industrial pollutants.

EMISSION CONTROL SYSTEM MAINTENANCE
The“Scheduled”maintenance services, listed inbold
typemust be done at the times or mileages specified to
assure the continued proper functioning of the emission
control system. These, and all other maintenance services
included in this manual, should be done to provide best

tenance may be needed for vehicles in severe operating
conditions such as dusty areas and very short trip
driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the
emission control devices and systems on your vehicle
may be performed by any automotive repair establish-
ment or individual using any automotive part which has
been certified pursuant to U.S. EPA or, in the State of
California, California Air Resources Board regulations.
MAINTENANCE SCHEDULES
There are two maintenance schedules that show the
requiredservice for your vehicle.
First is Schedule“B”. It is for vehicles that are operated
under the conditions that are listed below and at the
beginning of the schedule. Change the automatic trans-

the vehicle is usually operated under one or more of the
conditions marked with an.
•Day or night temperatures are below 32°F(0°C).
•Stop and go driving.
•Extensive engine idling.
