2013 FORD F150 suspension

On some 4WD vehicles, when the transfer case is in the N (Neutral)
position, the engine and transmission are disconnected from the rest of
the driveline. Therefore, the vehicle is free to roll even if the automatic
transmission is in P (Park) or the manual transmission is in gear. Do not
leave the vehicle unattended with the transfer case in the N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.
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.
Snow plow restriction
WARNING:Ford does not recommend the use of any F-150
model to be upfitted and equipped with snow plow hardware for
use as a snow plow vehicle.

PRINCIPLES OF OPERATION
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction or wheel/tire size may change the handling characteristics
of the vehicle and may adversely affect the performance of the
AdvanceTracsystem. In addition, installing any stereo loudspeakers
may interfere with and adversely affect the AdvanceTracsystem.
Install any aftermarket stereo loudspeaker as far as possible from the
front center console, the tunnel, and the front seats in order to
minimize the risk of interfering with the AdvanceTracsensors.
Reducing the effectiveness of the AdvanceTracsystem could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracsystem is an indication that at least
some of the tires have exceeded their ability to grip the road; this could
reduce the operator’s ability to control the vehicle potentially resulting
in a loss of vehicle control, vehicle rollover, personal injury and death. If
your AdvanceTracsystem activates, SLOW DOWN.
The AdvanceTracwith Roll Stability Control™ (RSC) system helps
you keep control of your vehicle when on a slippery surface. The
electronic stability control (ESC) portion of the system helps avoid skids
and lateral slides and roll stability control helps avoid a vehicle rollover.
The traction control system (TCS) helps avoid drive wheel spin and loss
of traction. For details on TCS operation, see theTraction Control
chapter.

permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.
When a steering system error is detected, the following messages may
appear in the information display:
•Service Power Steering
•Service Power Steering Now
•Power Steering Assist Fault
Hydraulic steering (6.2L engine)
Your vehicle is equipped with a hydraulic steering system.
To help prevent damage to the power steering system, never hold the
steering wheel at its furthest turning points (until it stops) for more than
a few seconds when the engine is running. If the power steering system
breaks down (or if the engine is turned off), you can steer the vehicle
manually, but it takes more effort.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
Steering Tips
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper vehicle alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Note:For information on electrical items such as fuses or relays, see the
Fuseschapter.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components periodically during, and after, any towing operation.
Load Placement
To help minimize how trailer movement affects the vehicle when driving:
•Load the heaviest items closest to the trailer floor.
•Load the heaviest items so they are centered between the left and
right side trailer tires.
•Load the heaviest items above the trailer axles or just slightly forward
toward the trailer tongue. Do not allow the final trailer tongue weight
to go above or below 10–15% of the loaded trailer weight.
•Select a tow bar with the correct rise or drop. When both the loaded
vehicle and trailer are connected, the trailer frame should be level, or
slightly angled down toward the vehicle, when viewed from the side.
When driving with a trailer or payload, a slight takeoff vibration or
shudder may be present due to the increased payload weight. Additional
information regarding proper trailer loading and setting your vehicle up
for towing is noted underLoad limitin theLoad Carryingchapter and
in theRV & Trailer Towing Guide,available at your authorized dealer.

•Dry the vehicle with a chamois or soft, terry cloth towel in order to
eliminate water spotting.
•It is especially important to wash the vehicle regularly during the
winter months, as dirt and road salt are difficult to remove and cause
damage to the vehicle.
•Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to the vehicle’s
paintwork and trim over time. Use MotorcraftBug and Tar Remover
(ZC-42), which is available from your authorized dealer.
•Remove any exterior accessories, such as antennas, before entering a
car wash.
•Suntan lotions and insect repellents can damage any painted surface;
if these substances come in contact with your vehicle, wash off as
soon as possible.
•If your vehicle is equipped with running boards, use Motorcraft Detail
Wash (ZC-3-A), and, as required, Motorcraft Bug and Tar Remover
(ZC-42), both as per the directions on the products’ labels. To
manually dry, use a clean, dry, lint-free towel. Do not use rubber,
plastic and vinyl protectant products on the running board surface, as
the area may become slippery.
Exterior Chrome
•Wash the vehicle first, using cool or lukewarm water and a neutral pH
shampoo, such as MotorcraftDetail Wash (ZC-3-A).
•Use MotorcraftCustom Bright Metal Cleaner (ZC-15), available from
your authorized dealer. Apply the product as you would a wax to
clean bumpers and other chrome parts; allow the cleaner to dry for a
few minutes, then wipe off the haze with a clean, dry rag.
•Never use abrasive materials, such as steel wool or plastic pads, as
they can scratch the chrome surface.
Underbody
Flush the complete underside of your vehicle frequently. Keep body and
door drain holes free from packed dirt.
Rear suspension components may require regular cleaning with a power
washer or a thorough rinse with a strong stream of water if the vehicle is
operated in dusty or muddy environments. Rear leaf springs or other
suspension components may emit squeak or popping noises while
operating the vehicle if particles, such as dirt, rocks, or other debris, are
present in the components.

Tire Replacement Requirements
WARNING:Only use replacement tires and wheels that are the
same size, load index, speed rating and type (such as P-metric
versus LT-metric or all-season versus all-terrain) as those originally
provided by Ford. The recommended tire and wheel size may be found on
either the Safety Compliance Certification Label (affixed to either the door
hinge pillar, door-latch post, or the door edge that meets the door-latch
post, next to the driver’s seating position), or the Tire Label which is
located on the B-Pillar or edge of the driver’s door. If this information is
not found on these labels, then you should contact your authorized dealer
as soon as possible. Use of any tire or wheel not recommended by Ford
can affect the safety and performance of your vehicle, which could result
in an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death. Additionally the use of non-recommended tires and
wheels could cause steering, suspension, axle, transfer case or power
transfer unit failure. If you have questions regarding tire replacement,
contact your authorized dealer as soon as possible.
WARNING:When mounting replacement tires and wheels, you
should not exceed the maximum pressure indicated on the
sidewall of the tire to set the beads without additional precautions
listed below. If the beads do not seat at the maximum pressure
indicated, re-lubricate and try again.
When inflating the tire for mounting pressures up to 20 psi (1.38 bar)
greater than the maximum pressure on the tire sidewall, the following
precautions must be taken to protect the person mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 ft (3.66 m) away from the tire wheel
assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi (1.38 bar) greater than the
maximum pressure, a Ford dealer or other tire service professional
should do the mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 ft (3.66 m) away from the tire
wheel assembly.
Your vehicle is equipped with tires designed to provide a safe ride and
handling capability.

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 (if equipped) may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire Rotation
WARNING:If the tire label shows different tire pressures for the
front and rear tires and the vehicle is equipped with TPMS (tire
pressure monitoring system), then the settings for the TPMS sensors
need to be updated. Always perform the TPMS reset procedure after
tire rotation. If the system is not reset, it may not provide a low tire
pressure warning when necessary. See the TPMS reset procedure in
this chapter.
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire and
wheel assembly. A dissimilar spare tire and wheel assembly is defined as
a spare tire and wheel that is different in brand, size or appearance from
the road tires and wheels. If you have a dissimilar spare tire and wheel
assembly, it is intended for temporary use only and should not be used
in a tire rotation.
Note:After having your tires rotated, check tire pressure and adjust to
the recommended inflation pressure.
Rotating your tires at the recommended interval (as indicated in the
Scheduled Maintenancechapter) will help your tires wear more evenly,
providing better tire performance and longer tire life.

Sometimes irregular tire wear can be corrected by rotating the tires.
USING SNOW CHAINS
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and performance
of your vehicle, which could result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and death. Additionally, the use
of non-recommended tires and wheels could cause steering, suspension,
axle or transfer case/power transfer unit failure.
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.
Note:Do not place chains on the following tires sizes: P265/60R18,
P275/65R18, LT275/65R18, LT315/70R17, P275/55R20, and P275/45R22.
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 SAE Class S chains.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•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.
