BRAKE FLUID CHECK
WARNING: Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death. WARNING:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING:
A fluid level between
the MAX and MIN lines is within the
normal operating range and there is no
need to add fluid. A fluid level not in the
normal operating range could
compromise the performance of the
system. Have your vehicle checked
immediately. To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.
Only use fluid that meets Ford
specifications. See
Capacities and
Specifications (page 352).
CHANGING THE 12V BATTERY
The battery is under the driver seat.
Note: If you have power seats and the
battery has no charge, jump-start your
vehicle to move the seat. See
Jump
Starting the Vehicle (page 251).
