Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle should stay in the normal
operating range. 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.

Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
Tread Lightly is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest
Service and the Bureau of Land Management in encouraging you to help
preserve our national forest and other public and private lands by
treading lightly.
Driving on hilly or sloping terrain
Note:Avoid driving crosswise or turning on steep slopes or hills.
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down. . A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
When climbing a steep slope or hill, start in a lower gear rather than
downshifting to a lower gear from a higher gear once the ascent has
started. This reduces strain on the engine and the possibility of stalling.
If you do stall out, do not try to turn around because you might roll over.
It is better to back down to a safe location.
Four-Wheel Drive (If Equipped)217

•Add particular accessories to your vehicle (e.g.; bug deflectors,
rollbars or light bars, running boards, ski racks).
•Drive with the wheels out of alignment.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
DRIVING THROUGH WATER
Note:Driving through deep water may allow water into the transmission
and engine causing internal damage. Have the fluid checked and, if water
is found, replace the fluid.
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine’s air intake and severely damage your engine.

If you notice any of the following:
•the engine coolant temperature gauge moves fully into the red (hot)
area
•the coolant temperature warning light illuminates
•the service engine soon indicator illuminates
1. Pull off the road as soon as safely possible and place the vehicle in P
(Park).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After several minutes, if this does not
happen, follow the remaining steps.
3. Turn the engine off and wait for it to cool before checking the coolant
level.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
4. If the coolant level is normal, you may restart your engine and
continue on.
5. If the coolant is low, add coolant, restart the engine and take your
vehicle to an authorized dealer. SeeAdding engine coolantin this
chapter for more information.
Refer to fail-safe cooling for additional information.
TRANSMISSION FLUID CHECK
Checking Automatic Transmission Fluid (If Equipped)
Refer to yourScheduled Maintenance Informationfor scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, i.e., if the transmission slips or
shifts slowly or if you notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 20 miles [30 km]). Verify that the
transmission fluid temperature gauge, located on the instrument cluster,
is within normal range.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.

Correct Fluid Level
For vehicles equipped with 5-speed transmissions, the fluid should be
checked at normal operating temperature 150°F-170°F (66°C-77°C) on a
level surface. For vehicles equipped with 6-speed transmissions, the fluid
should be checked at normal operating temperature 196°F-216°F
(91°C-102°C) on a level surface. The normal operating temperature can
be reached after approximately 20 miles (30 km) of driving.
Type A
Type B
High Fluid Level
Type A
Type B
Fluid levels above the safe range may result in transmission failure. An
overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
High fluid levels can be caused by an overheating condition.

Note:Automatic transmissions that require MERCON® LV should only use MERCON® LV fluid.
Use of any fluid other than the recommended fluid may cause transmission damage.4Indicates 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.5Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil must meet or exceed
the requirements of Ford specification WSS-M2C945-A, SAE 5W-20, and display the API Starburst
Certification Mark.6If the Ford specification is not shown on the oil container, the oil container must display the API
Starburst Certification Mark and the correct viscosity.7Refer toChecking automatic transmission fluidin this chapter for the correct dipstick type.
