DRAIN WATER SEPARATOR (Diesel engine only)— Displayed
when the water separator has reached a predetermined capacity and
needs to be drained. Refer to your6.0 and 6.4 Liter Power Stroke
Direct Injection Turbo Diesel Owner’s Guide Supplementfor more
information.
STOP SAFELY NOW (Diesel engine only)— Displays and a chime
sounds when the vehicle exhaust system temperature exceeds intended
operating range. If this warning occurs, the engine power is reduced and
the engine will shutdown when the vehicle speed is below 3 mph
(5 km/h).Stop the vehicle as soon as safely possibleand contact
your authorized dealer. Depending on the severity of the
over-temperature condition, the vehicle may or may not restart after
cycling the ignition off. If the vehicle restarts, there may be limited
power, or there could be full function. If the exhaust over-temperature
condition reoccurs the message center will display, STOP SAFELY NOW,
the chime will sound, the engine power will be reduced again and shut
down below 3 mph (5km/h).
ENGINE TURNS OFF IN XX (Diesel engine only)— Displayed
when the vehicle is in the final 30 seconds of a countdown to where the
engine will intentionally be turned off by the PCM. The diesel engine
shutdown is a (Regulatory) requirement which may be required of a
particular diesel vehicle for sale in States requiring this feature.
ENGINE TURNED OFF (Diesel engine only)— Displayed after the
30 second countdown.
ENGINE WARMING PLEASE WAIT XX (Diesel engine only)—
Displayed in extremely cold weather; typically around –15°F (–26°C).
The accelerator pedal will not respond to pressing; this is done so the
engine oil can be properly circulated to avoid engine damage from lack
of lubrication. A timer will begin a countdown from 30 seconds, then OK
TO DRIVE will display once the counter has reached 0 (zero) and the
accelerator pedal will respond to pressing.
OK TO DRIVE (Diesel engine only)— Displayed when the time
counter has reached 0 (zero) and the engine is sufficiently warm enough
to drive in extremely cold weather (refer to the ENGINE WARMING
description mentioned previously).

1Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford Specification
EST-M2C118–A for complete refill of limited slip Ford axles. Ford design rear axles contain a
synthetic lubricant that does not require changing unless the axle has been submerged in water.2Add the coolant type originally equipped in your vehicle.3Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are
indicated on the dipstick blade or the dipstick handle. Check the container to verify the fluid being
added is of the correct type. Refer to yourscheduled maintenance informationto determine the
correct service interval.
Automatic transmissions that require MERCONLV should only use MERCONLV fluid.
Use of any fluid other than the recommended fluid may cause transmission damage.4Service refill capacity is determined by filling the transmission to the bottom of the filler hole with
the vehicle on a level surface. The 6–speed manual transmission is equipped with an in-tank cooler.
Verify the fluid level after operating vehicle to ensure correct fluid level.5Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler. The amount of transmission fluid and fluid level should be set
by the indication on the dipstick’s normal operating range.6Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C930-A and the API Certification mark.
