other government authorities or other third parties acting with lawful
authority. Other parties may seek to access the information
independently of Ford Motor Company and Ford of Canada.

Poor wiper quality can sometimes be improved by cleaning the wiper
blades, refer toWindows and wiper bladesin theCleaningchapter.
To prolong the life of the wiper blades, it is highly recommended to

Important SRS precautions
The SRS is designed to work with
the safety belt to help protect the
driver and right front passenger
from certain upper body injuries.
Airbags DO NOT inflate slowly;
there is a risk of injury from a
deploying airbag.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The National Highway Traffic Safety Administration (NHTSA)
recommends a minimum distance of at least 10 inches (25 cm)
between an occupant’s chest and the driver airbag module.
Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
Ford Motor Company recommends that a certified technician
inspect all steering column assemblies in use in vehicles involved
in a collision. Failure to inspect and if necessary replace the steering
column assembly could result in severe injury or death in the event of
a collision.

Seating and Safety Restraints

Page 112 of 256

Do not attempt to service, repair, or modify the steering column,
its adaptive module, or its fuses. See your Ford or
Lincoln/Mercury dealer.
To properly position yourself away from the airbag:
•Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
•Recline the seat slightly one or two degrees from the upright position.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the airbag
supplemental restraint systems or its fuses. See your Ford or
Lincoln/Mercury dealer.
The front passenger airbag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the airbag system, increasing the
risk of injury. Do not modify the front end of the vehicle.
