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!
Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements — Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a 4 and 7-pin
wiring harness. Use a factory approved trailer harness
and connector.
NOTE:Do not cut or splice wiring into the vehicle’s
wiring harness.

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 vehicle to a complete stop.
2. Shut engine OFF.
3. Turn the ignition key to the ON position without
starting the engine.
4. Depress brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using the point of a ballpoint pen or similar object,
depress the recessed transfer case NEUTRAL button for
four seconds.7. After shift is completed and the NEUTRAL light
comes on, release the NEUTRAL button.
8. Start the engine.
9. Shift the transmission into REVERSE.
10. Release brake pedal for five seconds and ensure that
there is no vehicle movement.
11. Repeat steps 9 and 10 with the transmission in
DRIVE.
12. Turn ignition key to the unlocked OFF position.
13. Shift the transmission into PARK.
14. Attach vehicle to tow vehicle with tow bar.
NOTE:Items 1 through 5 are requirements that must be
met prior to depressing the NEUTRAL selection button,
and must continue to be met until the four seconds
elapses and the shift has been completed.

If any of these requirements (with the exception of Step 3
- Key ON) are not met prior to depressing the NEUTRAL
button or are no longer met during the four second timer,
then the NEUTRAL indicator light will flash continu-
ously until all requirements are met or until the NEU-
TRAL button is released.
NOTE:The ignition key must be ON for a shift to take
place and for the position indicator lights to be operable.
If the key is not ON, the shift will not take place and no
position indicator lights will be on or flashing.
CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into PARK with the transfer case in
NEUTRAL and the engine RUNNING. With the
transfer case in NEUTRAL, ensure that the engine is
OFF prior to shifting the transmission into PARK.
Shifting Out of NEUTRAL
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring vehicle to a complete stop.
2. Shut engine OFF.
3. Turn the ignition key to the ON position without
starting the engine.
4. Depress brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using the point of a ballpoint pen or similar object,
depress the recessed transfer case NEUTRAL button for
one second.
7. After the NEUTRAL indicator light turns off, release
the NEUTRAL button.

JUMP-STARTING PROCEDURES
WARNING!
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Don’t lean over battery when attaching
clamps or allow the clamps to touch each other. If
acid splashes in eyes or on skin, flush the contami-
nated area immediately with large quantities of
water.
•A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes. Do not use a booster battery
or any other booster source with an output that
exceeds 12-Volts.
Check the Battery Test Indicator (if equipped). If a light or
bright colored dot is visible in the indicator, DO NOT
jump-start the battery.If the indicator is dark or shows a green dot, proceed as
follows:
1. Wear eye protection and remove all metal jewelry such
as watch bands or bracelets which might make an
unintended electrical contact.
2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake, place
the automatic transmission in PARK and turn the ignition
OFF on both vehicles.
3. Turn OFF the heater, radio and all unnecessary elec-
trical loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.

•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
•Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased
emissions.
Brake System
Brake Master Cylinder — Fluid Level Check
The fluid level in the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
brake system warning light is on. If necessary, add fluid
to bring level to the full mark on the side of the reservoir
of the brake master cylinder. Be sure to clean the top of
the master cylinder area before removing the cap. With
disc brakes, fluid level can be expected to fall as the brakepads wear. Brake fluid level should be checked when
pads are replaced. If the brake fluid level is abnormally
low, check system for leaks.
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
WARNING!
•Use of brake fluid that may have a lower initial
boiling point, or is unidentified as to specifica-
tions may result in sudden brake failure during
hard prolonged braking. You could have an
accident.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.

required into the dipstick tube.Do not overfill.After
adding any quantity of oil through the oil fill tube, wait
a minimum of two minutes for the oil to fully drain into
the transmission before rechecking the fluid level.
NOTE:If it is necessary to check the transmissionbelow
the operating temperature, the fluid level should be
between the two “COLD” (lower) holes on the dipstick
with the fluid at approximately 70°F (21°C) (room tem-
perature). If the fluid level is correctly established at
room temperature, it should be between the “HOT”
(upper) reference holes when the transmission reaches
180°F ( 82°C). Remember it is best to check the level at the
normal operating temperature.CAUTION!
Be aware that if the fluid temperature is below 50°F
(10°C) it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading.
7. Check for leaks. Release parking brake.
To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make certain that the
dipstick cap is properly reseated. It is normal for the
dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.

•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
Required Maintenance Intervals
NOTE:** Vehicles built with the 4.7L engine are
equipped with 16 spark plugs; one set is located on the
top of the engine under the coils and the second set is
located on the side of the engine.
The spark plugs located under the coils are a standard
plug and must be changed every 30,000 miles
(50 000 km).
The spark plugs located on the side of the engine are a
premium plug and must be changed every 102,000 miles
(170 000 km).
