Ford F-350 (2017 year). Manual — part 25

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 your 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 by an
authorized dealer.

Engine Coolant Temperature
Gauge

WARNING

Never remove the coolant reservoir
cap when the engine is running or
hot.

Indicates engine coolant temperature. At
normal operating temperature, the level
indicator will be in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
safely possible, switch off the engine and
let the engine cool.

Fuel Gauge

Note: The fuel gauge may vary slightly
when your vehicle is moving or on a gradient.

Switch the ignition on. The fuel gauge will
indicate approximately how much fuel is
left in the fuel tank. The arrow adjacent to
the fuel pump symbol indicates on which
side of your vehicle the fuel filler door is
located.

The needle should move toward F when
you refuel your vehicle. If the needle points
to E after adding fuel, this indicates your
vehicle needs service soon.

After refueling some variability in needle
position is normal:

•

It may take a short time for the needle
to reach F after leaving the gas station.
This is normal and depends upon the
slope of pavement at the gas station.

•

The fuel amount dispensed into the
tank is a little less or more than the
gauge indicated. This is normal and
depends upon the slope of pavement
at the gas station.

•

If the gas station nozzle shuts off
before the tank is full, try a different
gas pump nozzle.

Low Fuel Reminder

A low fuel reminder triggers when the
distance to empty value reaches 50 mi
(80 km) to empty, with additional
warnings at 25 mi (40 km), 10 mi (20 km)
and 0 mi (0 km) to empty, provided the
message is cleared each time. An
additional warning at 75 mi (120 km) to
empty is provided when the MyKey is being
used.

Variations:

Note: The distance-to-empty warning can appear at different fuel gauge positions depending
on fuel economy conditions. This variation is normal.

Fuel gauge position

Distance-to-empty

Driving type (fuel economy

conditions)

1/8th tank

50 mi (80 km)

Highway driving

1/4 tank

50 mi (80 km)

Severe duty driving (trailer

towing, extended idle)

Transmission Fluid Temperature
Gauge

Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator will be in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop the vehicle as soon
as safely possible and verify the airflow is
not restricted such as snow or debris
blocking airflow through the grill. Also,
higher than normal operating temperature
can be caused by special operation
conditions (i.e. snowplowing, towing or
off-road use). See Special Operating
Conditions Scheduled Maintenance
(page 575). Operating the transmission for
extended periods with the gauge in the
higher than normal area may cause
internal transmission damage. You need
to alter the severity of your driving
conditions to lower the transmission
temperature into the normal range. If the
gauge continues to show high
temperatures, see an authorized dealer.

Turbo Boost Gauge

(If Equipped)

Indicates the amount of manifold air
pressure in the engine.

DEF Gauge

(If Equipped)

Indicates the current DEF level.

WARNING LAMPS AND
INDICATORS

The following warning lamps and
indicators will alert you to a vehicle
condition that may become serious. Some
lamps will illuminate when you start your
vehicle to make sure they work. If any
lamps remain on after starting your vehicle,
refer to the respective system warning
lamp for further information.

Note: Some warning indicators appear in
the information display and function the
same as a warning lamp but do not display
when you start your vehicle.

Adaptive Cruise Control

(If Equipped)

E144524

The speed control system
indicator light changes color to
indicate what mode the system

is in. See Using Adaptive Cruise Control
(page 240).

On (white light): Illuminates when the
adaptive cruise control system is turned
on. Turns off when the speed control
system is turned off.

Engaged (green light): Illuminates when
the adaptive cruise control system is
engaged. Turns off when the speed control
system is disengaged.

Adaptive Steering

(If Equipped)

E223375

The adaptive steering system
indicator illuminates if the
system detects a fault during the

continuous diagnostic checks.

Adaptive Steering Initialization (yellow,
flashing): The adaptive steering system
has detected a difference between
steering wheel angle and the desired road
wheel angle. The steering wheel adjusts
itself to correct this difference. This
adjustment is part of normal system
operation.

Adaptive Steering Off (yellow, solid): The
adaptive steering system is off. It is
possible that the steering wheel may not
be straight when the vehicle is driving
straight ahead. If this message persists,
see an authorized dealer.

Adaptive Steering Loss (red, solid): The
adaptive steering system integrity cannot
be verified. Do not drive the vehicle and
contact an authorized dealer immediately.
See Steering (page 256).

Anti-Lock Braking System

If it illuminates when you are
driving, this indicates a
malfunction. You will continue

to have the normal braking system
(without ABS) unless the brake system
warning lamp is also illuminated. Have the

If it illuminates when you are driving, check
that the parking brake is not engaged. If
the parking brake is not engaged, this
indicates low brake fluid level or a brake
system malfunction. Have the system
checked immediately by your authorized
dealer.

WARNING

Driving your vehicle with the warning
lamp on is dangerous. A significant
decrease in braking performance

may occur. It may take you longer to stop
your vehicle. Have your vehicle checked as
soon as possible. Driving extended
distances with the parking brake engaged
can cause brake failure and the risk of
personal injury.
