The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Using a step bumper
The rear bumper is equipped with an integral hitch and requires only a
ball with a 25.4 mm (one inch) shank diameter. The bumper hasa2270
kg (5 000 lb.) trailer weight and 227 kg (500 lb.) tongue weight
capability.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
Do not drive faster than 88 km/h (55 mph) when towing a trailer. Do not
drive faster than 72 km/h (45 mph) with any weight on the trailer while
towing on a hot day or in hilly country.
Speed control may shut off if you are towing on long, steep grades.
When towing a trailer:
²Use D (Drive) or a lower gear when towing up or down steep hills.
This will eliminate excessive downshifting and upshifting for optimum
fuel economy and transmission cooling.
²Anticipate stops and brake gradually.
When descending long, steep downhill grades, always use a lower gear to
provide engine braking to save wear on brakes. Use Drive (Overdrive
OFF) on moderately steep hills, Second (2) on steep hills, and First (1)
on very steep hills.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to the Severe Duty Schedule in your
ªService Guideº for more information.

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle's main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
Always replace the cover to the Power Distribution Box before
reconnecting the battery or refilling fluid reservoirs.

3. Raise the tire by turning the
wrench or handle clockwise.
Continue until the lift mechanism
ªclicks.º
4. Check that the tire is tightly
seated under the vehicle by pushing
against the tire. Retighten as
necessary.
5. Replace the access cover,
anti-theft bracket and thumb screw. Use finger pressure only to secure
the thumb screw.
Make sure the spare tire and jacking equipment are stowed and
secured in the proper storage location.
Never run the engine with one wheel off the ground.
Tire change procedure
Preparing to change the tire
1. Park on a level surface.
2. Activate the warning flashers.
3. Place the gearshift in P (Park)(automatic transmission) or R
(Reverse)(manual transmission).
4. Apply the parking brake.

5. Block the wheel that is diagonally
opposite the tire you are changing.
On E-Super Duty vehicles, the
parking brake is on the
transmission. Therefore, the vehicle
will not be prevented from moving
when a rear wheel is lifted, even if
the parking brake is applied. Be sure to block both directions of the
wheel that is diagonally opposite to the wheel that is being lifted.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
6. Remove the spare tire and jack
from the storage location.
7. Use the tapered end of the lug
nut wrench to unscrew wheel
ornaments attached by retaining
screws. Remove any wheel trim.
Insert the tapered end of the lug
nut wrench behind wheel covers or
hubcaps and twist off.
8. Loosen the wheel nuts by pulling
up on the handle of the lug nut
wrench about one-half turn
(counterclockwise). Do not remove
the wheel lug nuts until you raise
the tire off the ground.

Check the engine oil each time you fuel your vehicle.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. Protect yourself from engine heat.

TRANSMISSION FLUID
Checking and adding automatic transmission fluid
Follow the scheduled service intervals outlined in the ªService Guideº.
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and/or dipstick handle
and also in theLubricant specificationssection in theCapacities and
specificationschapter.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Do not drive the vehicle if the fluid
level is below the COLD (C) area on
the dipstick and outside
temperatures are above 10ÉC (50ÉF)
(see figure to the right).
Your transmission does not use up fluid. However, it is recommended
that you check the transmission fluid at least twice a year. The fluid level
should be checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Transmission fluid should be checked at normal operating temperatures
66ÉC-77ÉC (150ÉF-170ÉF) on a level surface. The normal operating
temperature can be reached after approximately 32 km (20 miles) of
driving.
The transmission fluid should be in
this range if at normal operating
temperature (66ÉC-77ÉC
[150ÉF-170ÉF]) (see figure to the
right).
The transmission fluid should be in
this range if at room temperature
(10ÉC-35ÉC [50ÉF-95ÉF]) (see figure
to the right).
If your vehicle has been operated for an extended period at high speeds,
in city traffic during hot weather or pulling a trailer, the vehicle should
be turned off for about 30 minutes to allow the fluid to cool before
checking.
1. Park the vehicle on a level surface and engage the parking brake.

2. With the parking brake engaged
and your foot on the brake pedal,
start the engine and move the
gearshift lever through all of the
gear ranges. Allow sufficient time
for each gear to engage.
3. Latch the gearshift lever in P (Park) and leave the engine running.
4. Remove the dipstick, wiping it clean with a clean, dry lint free rag.
5. Install the dipstick making sure it is fully seated in the filler tube.
6. Remove the dipstick and inspect the fluid level. The fluid level should
be in the HOT (H) area on the dipstick.
7. If necessary, add fluid in 250 ml (1/2 pint) increments through the
filler tube until the level is correct.
8. If an overfill occurs, excess fluid should be removed by a qualified
technician.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
If the fluid is above the hot area
range after driving the vehicle
approximately 30 km (20 miles),
excess transmission fluid should be
removed by a qualified technician.

lubrication. If the original universal joints are replaced with universal
joints equipped with grease fittings, lubrication will also be necessary.P R N D 2 1
