2013 FORD FOCUS service

WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands after handling.
Your vehicle is equipped with a Motorcraftmaintenance-free battery
which normally does not require additional water during its life of service.
Note:If your battery has a cover/shield, make sure it is reinstalled after
the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time.
To ensure proper operation of the battery management system (BMS), any
electrical devices that are added to the vehicle should not have their
ground connection made directly at the negative battery post. A connection
at the negative battery post can cause inaccurate measurements of the
battery condition and potential incorrect system operation.
Note:Electrical or electronic accessories or components added to the
vehicle by the dealer or the owner may adversely affect battery
performance and durability and may also affect the performance of other
electrical systems in the vehicle.
When a battery replacement is required, the battery should only be
replaced with a Ford recommended replacement battery that matches
the electrical requirements of the vehicle.
When the battery is disconnected or a new battery installed, the
automatic transmission must relearn its adaptive strategy. As a result of
this, the transmission may shift firmly when first driven. This operation is
considered normal and will fully update transmission operation to its
optimum shift feel.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
Note:Always dispose of automotive batteries in a responsible manner.
Follow your local authorized standards for disposal. Call your local
authorized recycling center to find out more about recycling automotive
batteries.

CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented to accommodate normal changes in pressure.
Condensation can be a natural by-product of this design. When moist air
enters the lamp assembly through the vents, there is a possibility that
condensation can occur when the temperature is cold. When normal
condensation occurs, a thin film of mist can form on the interior of the
lens. The thin mist eventually clears and exits through the vents during
normal operation. Clearing time may take as long as 48 hours under dry
weather conditions.
These are examples of acceptable condensation:
•Presence of thin mist (no streaks, drip marks or droplets).
•Fine mist covers less than 50% of the lens.
These are examples of unacceptable moisture (usually caused by a lamp
water leak):
•Water puddle inside the lamp.
•Large water droplets, drip marks or streaks present on the interior of
the lens.
Take your vehicle to a dealer for service if any of the above conditions of
unacceptable moisture are present.
Replacing Headlamp Bulbs
WARNING:Handle a halogen headlamp bulb carefully and keep
out of children’s reach. Grasp the bulb by only its plastic base
and do not touch the glass. The oil from your hand could cause the
bulb to break the next time the headlamps are operated.
Note:If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used.

Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
and one-half (1
12) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
WARNING:The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
Temperature A B C
WARNING:The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded. Excessive
speed, underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
The temperature grades are A (the highest), B and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 139. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.

INFORMATION CONTAINED ON THE TIRE SIDEWALL
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
Information on P Type Tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
A.P:Indicates a tire, designated by the Tire and Rim Association
(T&RA), that may be used for service on cars, SUVs, minivans and light
trucks.
Note:If your tire size does not begin with a letter, this may mean it is
designated by either ETRTO (European Tire and Rim Technical
Organization) or JATMA (Japan Tire Manufacturing Association).
B.215:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.

M.Maximum Permissible Inflation Pressure:Indicates the tire
manufacturers’ maximum permissible pressure and/or the pressure at
which the maximum load can be carried by the tire. This pressure is
normally higher than the manufacturer’s recommended cold inflation
pressure which can be found on 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 Tire Label which is located on the B-Pillar or the edge of
the driver’s door. The cold inflation pressure should never be set lower
than the recommended pressure on the vehicle label.
The tire suppliers may have additional markings, notes or warnings, such
as standard load, radial tubeless, etc.
Additional Information Contained on the Tire Sidewall for LT Type
