FUSE PRECAUTIONS

WARNING
Always disconnect the battery before servicing high-current fuses.

WARNING
To reduce the risk of electrical shock, always replace the cover to the powerdistribution box before reconnecting the battery or refilling fluidreservoirs.

TROUBLESHOOTING

• The Check Engine Light (also known as CEL):
  If your vehicle’s Check Engine Light is illuminated, you can recover the issuecodes with an OBD-II scanner. These codes have the potential to provideextremely helpful information regarding the issue.The check engine light(CEL) can be triggered by a variety of faults, the most common of which aredefective oxygen sensors, a loose gas cap or issues with the mass airflowsensor.

• Beginning Difficulties:
  If the truck would not start, examine the condition of the battery as well asthe connections to it. In many cases, the problem is caused by a dead orfailing battery. Check to see if there are any problems with the starter motorand the ignition system. It’s possible that you’ll need to replace a worn-outstarter or a broken ignition switch.

• Problems with Transmission:
  If you experience problems with the transmission, such as slipping gears orharsh shifting, have the transmission fluid level and condition checked.Transmission problems might arise if the fluid level is too low or it ispolluted.

• Problems with Electricity:
  Electrical problems can present itself in a variety of ways, including lightsthat don’t work, power windows that don’t work, or problems with theinformation and entertainment system. Check the wiring, as well as the fusesand relays, for any faults. If necessary, get in touch with an experienced carelectrician.

• Trouble with the Cooling System:
  An issue with the radiator, the thermostat, or the fan that controls thecooling might lead to overheating. Conduct a leak test on the cooling systemand check to see that it has the required amount of coolant.

• Both the Steering and the Suspension
  When you’re behind the wheel, if you feel vibrations, hear strange noises, orhave the steering wheel wobble, it’s possible that the problem is with thesuspension or the steering components. Examine the bushings, ball joints, andtie rods to see if any of them have become worn.

• Issues with the Breaks:
  Indicators of worn brake pads or rotors include squeaking or grinding soundswhen applying the brakes. Inspect the brake system and replace any worncomponents promptly for safety.

• Climate control with heating and cooling:
  If the heating, ventilation and air conditioning system is not operating as itshould, there may be a leak in the refrigerant line, a problem with the blowermotor or an issue with the temperature control unit.

• Exhaust System Problems:
  Excessive noise as well as a decrease in performance might result from exhaustsystem flaws such as leaks or holes. Conduct a thorough inspection of theexhaust system for any signs of damage or corrosion.

• Idling Roughly or Having Poor Performance:
  It’s possible that your Ford F-150’s power troubles, such as a rough idle or alack of power when accelerating, are the result of problems with the fuelsystem, such as a clogged fuel filter or a fuel injector that isn’t workingproperly.

• Spills of Oil:
  Make sure there are no oil leaks, paying close attention to the areas aroundthe engine and gearbox. Addressing oil leaks promptly can prevent moresignificant issues.

• Problems with Tyres:
  Handling and fuel efficiency can both be negatively impacted when tyres wearunevenly or are damaged. Maintain a routine inspection schedule for your tyresand rotate them as directed. Problems with the Drive Belt and the Pulley Checkfor signs of wear and damage on the pulleys and the drive belt, often known asa serpentine belt. A worn or loosened belt may be the cause of a squealingsound coming from the engine compartment.

• Problems with the Power Steering:
  If the power steering is not functioning properly or is making noise, checkthe level and quality of the power steering fluid. There may be a leaksomewhere in the system or the power steering pump may just be old and wornout.

• Fuel System Maintenance:
  Utilise gasoline of a high-quality, and take into consideration the use offuel system cleaners on a recurrent basis, in order to maintain a clean fuelsystem.

Safety Instruction

• Seat Belts:
  It is imperative that you at all times wear your seat belt, and it is yourresponsibility to ensure that other passengers do the same. Seat beltssignificantly reduce the risk of injury in the event of a collision. Childsafety requires that you use child safety seats or boosters that areappropriate for the child’s age and that you install them in accordance withthe guidelines provided by the manufacturer as well as any applicable locallaws.

• Avoid Distractions:
  Stay focused on driving. While you’re behind the wheel, you shouldn’t betalking on the phone, texting, eating, or engaged in any other activity thatcould distract you.

  When driving behind another vehicle, it is important to have a safe followingdistance between your Ford F-150 and the car in front of you. Under typicalcirc*mstances, the bare minimum recommended waiting time is three seconds.Always express Your Intentions with Your Turn Signals When changing lanes ormaking changes, you should always express your intentions with your turnsignals. The acts you do can then be anticipated by other drivers. Applyingthe brakes safely requires a smooth and progressive application in order toprevent jerky stops and skidding. In the event that your vehicle is outfittedwith an anti-lock braking system (ABS), make sure that you keep a strong andconsistent pressure on the brake pedal whenever you need to perform anemergency stop.

• Use of Mirrors and Perform Shoulder Checks:
  When you want to be aware of your surroundings and potential blind spots, besure to check your mirrors regularly and perform shoulder checks. Taking careof your tyres involves ensuring they have the right amount of tread depth andare inflated to the correct pressure. Tyres that are underinflated or worn outcan have a negative impact on a vehicle’s stability and handling.
