NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the “TOW HAUL OD/OFF” feature ON when
driving in hilly areas or shift the transmission to Drive
position 2 on more severe grades.
Towing Tips — Electronic Speed Control (If
Equipped)
\25
Do not use in hilly terrain or with heavy loads.
\25When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
\25Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
\25City Driving
When stopped for short periods of time, put transmission
in NEUTRAL and increase engine idle speed.
\25Highway Driving
Reduce speed.
\25Air Conditioning
Turn off temporarily.
SNOWPLOW
Snowplow Prep Packages are available as a factory
installed option. These packages include components
necessary to equip your vehicle with a snowplow.
NOTE: Before installation of a snowplow it is highly
recommended that the owner/installer obtain and follow
the recommendations contained within the current
300 STARTING AND OPERATING
Page 306 of 429
•Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
•Vehicles with automatic transmissions should use 4L
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
•Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
CAUTION!
Front or rear wheel lifts should not be used. Internal
damage to the transmission or transfer case will occur
if a front or rear wheel lift is used when recreational
towing.
Recreational Towing – 2-Wheel Drive Models
Recreational towing of 2-Wheel Drive models is not
allowed.Towing with the rear wheels on the ground can
result in severe transmission damage.

Recreational Towing – 4-Wheel Drive Models
CAUTION!
Failure to follow these requirements can cause severe
damage to the transmission and/or transfer case.
NOTE: Both the manual shift and electronic shift trans-
fer cases must be shifted into NEUTRAL for recreational
towing. Automatic transmissions must be shifted into the
PARK position for recreational towing. Refer to the
following for the proper transfer case NEUTRAL shifting
procedure for your vehicle.
Recreational Towing Procedure — Manual Shift
Transfer Case — If Equipped
Use the following procedure to prepare your vehicle for
recreational towing:
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL before recre-
ational towing to prevent damage to internal parts.
1. Bring the vehicle to a complete stop.
2. Shut OFF the engine.
3. Depress the brake pedal.
4. Shift transmission into NEUTRAL.
5. Shift transfer case lever into NEUTRAL.
6. Start the engine.
7. Shift transmission into REVERSE.
8. Release brake pedal for five seconds and ensure that
there is no vehicle movement.

WARNING!
After using the jack and tools, always reinstall them
in the original carrier and location. While driving
you may experience abrupt stopping, rapid accelera-
tion, or sharp turns. A loose jack, tools, bracket or
other objects in the vehicle may move around with
force, resulting in serious injury.
4500/5500 Models
These vehicles do not come equipped with a jack.
NOTE:Jacking and tire changing on 4500/5500 models
should be performed by an authorized dealer, or knowl-
edgeable service personnel with the appropriate heavy
duty equipment, like a tire service company.
Preparations For Jacking
1. Park the vehicle on a firm level surface. Avoid ice or
slippery areas.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
2. Set the parking brake.
3. Place the shift lever into PARK (automatic transmis-
sion) or REVERSE (manual transmission). On 4-Wheel
drive vehicles, shift the transfer case to the “4L” position.
4. Turn OFF the ignition.
5. Turn on the Hazard Warning flasher.

6. Block both the front and rear of the
wheel diagonally opposite the jacking
position. For example, if the right front
wheel is being changed, block the left
rear wheel.
NOTE: Passengers should not remain in the vehicle
when the vehicle is being jacked.

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.

NOTE:The transfer case must be in the neutral position,
and the transmission must be in PARK (automatic trans-
mission), or in gear (manual transmission) to tow a
4-Wheel Drive vehicle with one end of the vehicle raised.
The manufacturer recommends towing with all wheels
OFF the ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of vehicle raised and
the opposite end on a towing dolly.
2–Wheel Drive Vehicles
Provided that the transmission is operable, tow with the
transmission in NEUTRAL and the ignition key in the
OFF position along with the front wheels raised and the
rear wheels on the ground. Speed must not exceed
30 mph (50 km/h) and distance must not exceed 15 miles
(25 km).
CAUTION!
Towing faster than 30 mph (50 km/h) or for more than
15 miles (25 km) can cause severe damage to the
transmission.
If the vehicle is to be towed faster than 30 mph (50 km/h)
or more than 15 miles (25 km) the vehicle must be towed
with the rear wheels raised and the front wheels on the
ground. It may also be towed on a flatbed or with the
front wheels raised and the rear wheels on a dolly.
