light FORD EXPEDITION 2023 Service Manual

Avoid driving at excessive speed. Thiscauses vehicle momentum to work againstyou and your vehicle could become stuckto the point that assistance may berequired from another vehicle. Remember,you may be able to back out the way youcame if you proceed with caution.
DRIVING THROUGH MUD ANDWATER
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even four-wheel drive vehicles canlose traction in slick mud. If your vehicledoes slide, steer in the direction of the slideuntil you regain control of your vehicle.After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts can cause an imbalance thatcould damage drive components.
Water
If you must drive through high water, driveslowly. Traction or brake capability maybe limited. When driving through water,determine the depth and avoid waterhigher than the bottom of the hubs. If theignition system gets wet, your vehicle maystall. Once through water, test the brakes.Wet brakes do not stop your vehicle aseffectively as dry brakes. Drying improvesby applying light pressure to the brakepedal while moving slowly.
Note:Driving through deep water maydamage the transmission. If the front or rearaxle is submerged in water, the axlelubricant and transfer case lubricant shouldbe checked and changed if necessary.
DRIVING ON HILLY OR SLOPINGTERRAIN
Although natural obstacles may make itnecessary to travel diagonally up or downa hill or steep incline, you should try to drivestraight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you can use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try toturnaround because this could causevehicle roll over. It is better to reverse backto a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power can causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral. Disengageoverdrive or move the transmissionselector lever to a lower gear. Whendescending a steep hill, avoid sudden hardbraking as you could lose control. The frontwheels have to be turning in order to steeryour vehicle.

WHAT IS REVERSE BRAKING
ASSIST
Reverse braking assist is designed toreduce impact damage or assist in avoidinga collision while in reverse (R). Usingsensors on the rear of the vehicle, it candetect a possible collision and apply thebrakes. If full braking occurs, the systemattempts to stop the vehicle a safedistance from the obstacle.
HOW DOES REVERSE
BRAKING ASSIST WORK
Reverse braking assist functions when inreverse (R) and traveling at a speed of1–7 mph (2–12 km/h).
If the system detects an obstacle behindyour vehicle, it provides a warning throughthe rear parking aid or cross traffic alertsystem.
REVERSE BRAKING ASSIST
PRECAUTIONS
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result inthe loss of control of your vehicle,personal injury or death.
WARNING: To help avoid personalinjury, always use caution when inreverse (R) and when using the sensingsystem.
WARNING: The system may notoperate properly during severe weatherconditions, for example snow, ice, heavyrain and spray. Always drive with duecare and attention. Failure to take caremay result in a crash.
WARNING: Traffic control systems,fluorescent lamps, inclement weather,air brakes, external motors and fans mayaffect the correct operation of thesensing system. This may cause reducedperformance or false alerts.
WARNING: Some situations andobjects prevent hazard detection. Forexample low or direct sunlight, inclementweather, unconventional vehicle types,and pedestrians. Apply the brakes whennecessary. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: Do not use the systemwith accessories that extend beyond thefront or rear of your vehicle, for examplea trailer hitch or bike rack. The system isnot able to make corrections for theadditional length of the accessories.

HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo speakers mayinterfere with and adversely affect theelectronic stability control system.Reducing the effectiveness of theelectronic stability control system couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It's always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator's ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death.
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result inthe loss of control of your vehicle,personal injury or death.
If a driving condition activates either thestability control or traction control you mayexperience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or moreof the wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances yourvehicle’s ability to prevent rollovers bydetecting your vehicle’s roll motion andthe rate at which it changes by applyingthe brakes to one or more wheelsindividually.
Curve Control
Curve control enhances your vehicle’sability to follow the road when corneringseverely or avoiding objects in the roadway.Curve control operates by reducing enginepower and, if necessary, applying brakesto one or more of the wheels individually.
