WARNING: Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system: If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness: If this light fails
to illuminate when the ignition is
turned to on, continues to flash or
remains on, have the system
serviced immediately by your
authorized dealer. A chime will sound if there is a malfunction in the
indicator light.
Safety belt: Reminds you to fasten
your safety belt. A Belt-Minder 
chime will also sound to remind you
to fasten your safety belt. Refer to
the Seating and Safety Restraints
chapter to activate/deactivate the Belt-Minder  chime feature.
Charging system: Illuminates when
the battery is not charging properly.
If it stays on while the engine is
running, there may be a malfunction
with the charging system. Contact your authorized dealer as soon as
possible. This indicates a problem with the electrical system or a related
component.
Engine oil pressure (RTT and
static warning light): Displays
when the oil pressure falls below the
normal range. Refer to Engine oil
in the Maintenance and Specifications chapter.ABSInstrument Cluster

GAUGES
Base cluster with automatic transmission shown. Metric similar.
1. Engine oil pressure gauge: Indicates engine oil pressure. The
needle should stay in the normal operating range (between L and H). If
the needle falls below the normal range, stop the vehicle, turn off the
engine and check the engine oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked at your authorized dealer.
2. Engine coolant temperature gauge: Indicates engine coolant
temperature. At normal operating temperature, the needle will be in the
normal range (between H and C). If it enters the red section, the
engine is overheating. Stop the vehicle as soon as safely possible,
switch off the engine and let the engine cool.
WARNING: Never remove the coolant reservoir cap while the
engine is running or hot.
3. Transmission fluid temperature gauge: If the gauge is in the:
Normal area The transmission fluid is within the normal operating
temperature (between H and C).
Yellow area The transmission fluid is higher than normal operating
temperature. This can be caused by special operation conditions (i.e.
snowplowing, towing or off road use). Refer to Special operating
conditions in the scheduled maintenance information for instructions.
Operating the transmission for extended periods of time with the gauge
in the yellow area may cause internal transmission damage. km/h

lubrication. A timer will begin a countdown from 30 seconds. Once the
counter has reached 0 seconds, OK TO DRIVE will be displayed and the
engine will respond to accelerator pedal movement. Refer to your diesel
supplement for more information.Instrument Cluster

LOW FUEL PRESSURE SEE MANUAL (diesel engine only) —If
this message appears during a cold start or during cold operation 32°F
(0°C) up to 10 minutes after the initial cold start; monitor the message
center and if it disappears and does not re-appear after the engine has
fully warmed up, the low fuel pressure message is most likely caused by
waxed or gelled fuel. To prevent this, use an anti-gel additive. Refer to
your diesel supplement for more information. The customer warranty
may be void from using additives that do not meet or exceed Ford
specifications. If the low fuel pressure message persistently appears after
re-fueling during the cold start and cold operation conditions defined
previously and then disappear when the engine has fully warmed up,
consider different fuel sources.Instrument Cluster
