Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
information for more information.
Trailer towing tips
• Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
• Allow more distance for stopping with a trailer attached.
• The trailer tongue weight should be 10–15% of the loaded trailer
weight.
• If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCW, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to the Maintenance and specifications chapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 500 miles (800 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.
• After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
• To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(automatic transmission) or N (Neutral) (manual transmissions).
• Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
• do not allow the static water level to rise above the bottom edge of
the rear bumper.
• do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.

Exceeding these limits may allow water to enter vehicle components:
•causing internal damage to the components.
• affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.
Vehicles equipped with a manual transmission:
Note: 4x2 and 4x4 vehicles with a manual transmission follow these
guidelines for recreational towing:
Before you have your vehicle towed:
• Release the parking brake.
• Move the gearshift to the neutral position.
• Turn the key in the ignition to the OFF/UNLOCKED position.
• The maximum recommended speed is 55 mph (88 km/h).
• The maximum recommended distance is unlimited.
• Put 4x4 switch in 2WD mode (4x4 only)
• The vehicle must be towed in the forward position to ensure no
damage is done to the internal transmission components.
For 4x4 vehicles with a manual transmission, it is recommended that a
Neutral Tow Kit be purchased and installed by an authorized dealer if
the vehicle is towed frequently.
In addition, it is recommended that you follow the instructions
provided by the aftermarket manufacturer of the towing
apparatus if one has been installed.
Vehicles equipped with an automatic transmission
4x2 and 4x4 vehicles with an automatic transmission follow these
guidelines for recreational towing:
• Release the parking brake.

•Turn the key in the ignition to the OFF/UNLOCKED position.
• Place the transmission in N (Neutral).
• Do not exceed a distance of 50 miles (80 km).
• Do not exceed 35 mph (56 km/h) vehicle speed.
• Put 4x4 switch in 2WD mode (4x4 only)
• The vehicle must be towed in the forward position to ensure no
damage is done to the internal transfer case components.
For 4x4 vehicles with an automatic transmission, a Neutral Tow Kit must
be purchased and installed by an authorized dealer if a distance of
50 miles (80 km) or a speed of 35 mph (56 km/h) must be exceeded.
For 4x2 vehicles with an automatic transmission, if a distance of 50 miles
(80 km) or a speed of 35 mph (56 km/h) must be exceeded, you must
disconnect the rear driveshaft. It is recommended that the driveshaft be
removed/installed only by an authorized dealer. See your authorized
dealer for driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid or transfer case fluid loss, damage to the
driveshaft and internal transmission and transfer case
components.
CAMPER BODIES
Your pickup is not recommended for slide–in camper bodies.

N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
(Overdrive)
The normal driving position for the
best fuel economy. Transmission
operates in gears one through
five.
(Overdrive) can be
deactivated by pressing the
transmission control switch on the end of the gearshift lever.
This will illuminate the O/D OFF
lamp and activate Drive.
Drive (not shown)
Drive is activated when the transmission control switch is pressed.
• This position allows for all forward gears except overdrive.
• O/D OFF lamp is illuminated.
• Provides engine braking.
• Use when driving conditions cause excessive shifting from O/D to
other gears. Examples: city traffic, hilly terrain, heavy loads, trailer
towing and when engine braking is required.
• To return to O/D (overdrive mode), press the transmission control
switch. The O/D OFF lamp will not be illuminated.
• O/D (Overdrive) is automatically returned each time the key is turned
off.
2 (Second)
Use 2 (Second) to start-up on slippery roads or to provide additional
engine braking on downgrades.
1 (First)
• Provides maximum engine braking.
• Allows upshifts by moving gearshift lever.
• Will not downshift into 1 (First) at high speeds; allows for 1 (First)
when vehicle reaches slower speeds.

steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)WARNING: For important information regarding safe operation
of this type of vehicle, see Preparing to drive your vehicle in
this chapter.

not be operated on dry pavement; driveline damage may occur.
If equipped with the Electronic Shift 4WD System, and 4WD Low
is selected while the vehicle is moving above 3 mph (5 km/h), the
4WD system will not engage. This is normal and should be no
reason for concern. Refer toShifting to/from 4WD Low for proper
operation.
