If you check the power steering fluid when it is
cold, make sure that the fluid reaches the FULL
COLD range on the dipstick. The reading will
only be accurate if the fluid temperature is
approximately 50 to85ÊF (10 to 30ÊC).
*
[SV39405( ALL)06/93]
NOTE: Do not turn the steering wheel of your
vehicle with the engine off. It could
force power steering fluid out from the
reservoir cap or in extreme cases, it
could unseat the cap.

Suspension and Steering
[SV39420( M)06/90]
Modifications
[SV39430( M)06/90]
The suspension and steering systems on your
vehicle have been designed and tested to
provide both safe, predictable performance
whether loaded or empty as well as durable
load carrying capability. Any modifications to
the suspension or steering systems can reduce
your vehicle's performance capability and
adversely affect driver and passenger safety.
Ford recommends that you do not make
modifications such as adding or removing parts
(like lift kits or stabilizer bars) or by using
replacement parts not equivalent to the original
factory equipment.

RWARNING
The low pressure gas shock absorbers are
charged with nitrogen gas to 90 psi (620
kPa). Do not attempt to heat, puncture or
open.

Readiness for Inspection/Maintenance
Testing
*
[SV51457( ALL)06/95]
In some localities it may become a legal
requirement to pass an
Inspection/Maintenance (I/M) test of the
On-Board Diagnostic (OBD) II system. If the
vehicle's powertrain system or its battery has
just been serviced, the OBD II system is reset to
a ªnot ready for I/M testingº condition. To
prepare for I/M testing, the law specifies a
ªneed for additional mixed city and highway
driving to complete the checkº of the OBD II
system. As soon as all of the OBD II system
checks are successfully completed, the OBD II
system is set to the ready condition. The amount
of driving required to reach the ready condition
varies with individual driving patterns. To
complete this requirement in the minimum
amount of time, refer to the OBD II Drive Cycle
defined below. If the vehicle owner cannot or
does not want to do the additional driving
required by law, a service center can perform
this drive cycle as it would any other type of
repair work.
[SV51458( ALL)05/95]
OBD II Drive Cycle

[SV51459( ALL)05/95]
