Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, apply the brake steadily. Do not
pump the brakes. Refer to theBrakessection of this chapter for
additional information on the operation of the Anti-lock Brake System
(ABS).
Maintenance and modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.

•If your vehicle is equipped with Continuous Controlled Damping
Suspension (CCD Suspension), you can select NORMAL or SPORT
drive control modes for better experience while towing a trailer. See
the Information Displays chapter for details on selecting driving
modes.
• If you are towing a trailer frequently in hot weather, hilly conditions,
at the gross combined weight rating (or any combination of these
factors), consider refilling your rear axle with synthetic gear lubricant
(if the axle is not already filled with it). See the Capacities and
Specifications chapter for the lubricant specification.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in position P.
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not included with vehicle.)
Your vehicle may be equipped with a temporary or conventional spare
tire. A “temporary” spare tire is different in size (diameter or width),
tread-type (All-Season or All-Terrain) or is from a different manufacturer
than the road tires on your vehicle. Consult information on the tire label
or Safety Compliance label for limitations when using.
Launching or Retrieving a Boat or Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer beforebacking the trailer into
the water.
Note: Reconnect the wiring to the trailer afterremoving the trailer 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 centimeters)
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 anytime the rear axle submerges in
water. Water may have contaminated the rear axle lubricant, which does
not normally require checking or changing unless it is leaking or other
axle repair is required.

ADJUSTING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident, an authorized dealer should
check the alignment of your headlamps.
Vertical Aim Adjustment
Before aim adjustment, disable the air suspension system. Refer to
Message centerin theDriver Controls chapter.
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away. •(A) 8 feet (2.4 meters)
• (B) Center height of lamp to
ground
• (C) 25 feet (7.6 meters)
• (D) Horizontal reference line
2. Measure the height from the
center of your headlamp (indicated
by a 3.0 millimeter circle on the
lens) to the ground and mark an
8 foot (2.4 meter) horizontal
reference line on the vertical wall or screen at this height (a piece of
masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood. Cover one of the headlamps so no light from that lamp
hits the wall.
4. On the wall or screen you will
observe a light pattern with a
distinct horizontal edge towards the
right. If this edge is not at the
horizontal reference line, the beam
will need to be adjusted so the edge
is at the same height as the
horizontal reference line.

Safety Practices
WARNING:If your vehicle is stuck in snow, mud, or sand, do
not rapidly spin the tires. Spinning the tires can tear the tire and
cause an explosion. A tire can explode in as little as three to five
seconds.
WARNING: Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Driving habits have a great deal to do with your tire mileage and safety.
• Observe posted speed limits.
• Avoid fast starts, stops and turns.
• Avoid potholes and objects on the road.
• Do not run over curbs or hit the tire against a curb when parking.
Highway Hazards
No matter how carefully you drive, there is always the possibility that
you may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove the wheel and replace it with your spare tire and
wheel. If you cannot detect a cause, have the vehicle towed to the
nearest repair facility or tire dealer to have the vehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you are driving, the wheels may
be out of alignment. Have an authorized dealer check the wheel
alignment periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by an authorized dealer.
Front-wheel drive vehicles and those with an independent rear
suspension may require alignment of all four wheels.

Note:The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when using
snow tires and chains.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
• If possible, avoid fully loading your vehicle.
• Use only cable type chains or chains offered by Ford/Lincoln as an
accessory or equivalent. Other conventional link type chains may
contact and cause damage to the vehicle’s wheel house and/or body.
• Do not install chains on the front wheels as this may interfere with
suspension components.
• Only certain snow cables or chains have been approved by
Ford/Lincoln as safe for use on your vehicle with the following tires:
275/65R18.
• You should install snow cables or chains that have been rated as SAE
Class S.
• Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
• Do not exceed 30 mph (50 km/h) or less if recommended by the chain
manufacturer while using snow chains.
• Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and retighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
• Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
• Purchase chains or cables from a manufacturer that clearly labels body
to tire dimension restrictions. The snow chains or cables must be
mounted in pairs on the rear tires only.
If you have any questions regarding snow chains or cables, please
contact your Ford/Lincoln dealer.
