1999 Mercury Mountaineer towing

Never connect any trailer lighting to the vehicle's taillamp
circuits, because it may damage the electrical system resulting in
fire. Contact your local Ford dealership for assistance in proper trailer
tow wiring installation. Additional electrical equipment may be
required.
Using a step bumper
The rear bumper is equipped with an integral hitch and requires only a
ball with a 19 mm (3/4 inch) shank diameter. The bumper has a 1 590 kg
(3 500 lb.) trailer weight and 159 kg (350 lb.) tongue weight capability.
Use a frame-mounted weight distributing hitch for trailers over 1 590 kg
(3 500 lb).
Driving while you tow
Do not drive faster than 88 km/h (55 mph) when towing a trailer.
Speed control may shut off if you are towing on long, steep grades.
When towing a trailer:
²Use 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.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your Scheduled Maintenance guide
for more information.
Trailer towing tips
²Practice turning, stopping and backing up in an area 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.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10% of the loaded trailer weight.

²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
²Vehicles 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
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and
²Do not allow waves to break higher than 15 cm (six inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions, reliability and
causing internal transmission damage.
Replace the rear axle lubricant anytime 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.
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.
Recreational towing (all wheels on the ground)
Do not tow your vehicle with all wheels on the ground as vehicle damage
may occur.
LUGGAGE RACK
Maximum load is 75 kg (165 lbs), evenly distributed. If it is not possible
to distribute the load, position it as far rearward as possible. Adjustable
tie down loops (not equipped) must be used to secure the load.

Stowing the spare
1. Lay the tire on the ground with the valve stem facing up.
2. Slide the wheel under the vehicle
and install the retainer through the
wheel center.
3. Turn the jack handle clockwise
until the tire is raised to its original
position underneath the vehicle. The
jack handle ratchets when the tire is
raised to the stowed position. It will
not allow you to overtighten.
Tire change procedure
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
On vehicles equipped with Air Suspension, turn OFF the Air
Suspension switch prior to jacking, hoisting or towing your
vehicle.
Refer to the instruction sheet for detailed tire change instructions.
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
2. Place gearshift lever in P (Park)
and turn engine OFF.

4. Remove the jumper cable from the positive (+) terminal of the
disabled vehicle's battery.
After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can
relearnits idle conditions.
WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member, your roadside assistance center.
If equipped with air suspension, the air suspension control must be
turned to the OFF position.
The Ford approved towing procedure is flatbed or wheel lift with
dollies.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground (without dollies) and the rear wheels off the ground.
On 4x4 vehicles, it is recommended that your vehicle be towed with a
wheel lift or flatbed equipment with all the wheels off the ground.
Roadside emergencies
189

If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
Do not tow with slingbelt equipment. Ford Motor Company has not
developed or approved a T-hook or slingbelt towing procedure.
A towing manual is available from Ford Motor Company for all authorized
tow truck operators. Have your tow truck driver refer to this manual for
proper hook-up and towing procedures for your vehicle.

Conditions
²Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
²Carrying unnecessary weight may reduce fuel economy (approximately
2 km/h [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollover/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²Use of fuel blended with alcohol may lower fuel economy.
²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Flat terrain driving improves fuel economy over hilly roads.
²Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
²Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
²Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of Km/L (MPG) expected on
the vehicle, depending upon the driver's method of operation and
conditions.
