2023 FORD MUSTANG check engine

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 298).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Note:Depending on applicable laws andregulations in the country for which yourvehicle was originally built, your brake lampscould flash during heavy braking. Followingthis, your hazard lights may also flash whenyour vehicle comes to a stop.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you switch theignition on. If the light does notilluminate during start up, remains on orflashes, the anti-lock braking system maybe disabled. Have the system checked byan authorized dealer. If the anti-lock brakesystem is disabled, normal braking is stilleffective.
See Warning Lamps and Indicators(page 93).
Note:Indicators vary depending on region.
This lamp also illuminatesmomentarily when you switchthe ignition on to confirm thelamp is functional. If it does notilluminate when you switch theignition on, or begins to flash atany time, have the system checked by anauthorized dealer. If the brake warninglamp illuminates with the parking brakereleased, have the system checkedimmediately.

When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) or neutral (N)to aid engine and transmission coolingand to help air conditioningperformance.
•Switch off the speed control withheavy loads or in hilly terrain. Thespeed control may turn offautomatically when you are towing onlong, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a slope. However, ifyou must park on a slope:
1.Turn the steering wheel to point yourvehicle tires away from traffic flow.
2.Set your vehicle parking brake.
3.Place the automatic transmission inpark (P) or manual transmission in alow gear.

When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Any time the rear axle submerges in water,replace the rear axle lubricant. Water maycontaminate the rear axle lubricant, whichis not a normal maintenance inspectionitem unless there is a possibility of a leakor other axle repair is required.

If the engine coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 90).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends onambient temperature, vehicle load andterrain. The engine continues to operatewith limited power for a short period oftime.
If the engine temperature continues to rise,the fuel supply to the engine reduces. Theair conditioning switches off and the enginecooling fan operates continually.
1.Gradually reduce your speed and stopyour vehicle as soon as it is safe to doso.
2.Immediately switch the engine off toprevent severe engine damage.
3.Wait for the engine to cool down.
4.Check the coolant level. See EngineCoolant Check (page 265).
5.Have your vehicle checked as soon aspossible.
Reduced Vehicle Top Speed
Your vehicle's ability to reach and maintaintop speed is partially dependent uponambient temperature. Under certainenvironmental conditions, your vehicle'stop speed may be reduced to protectpowertrain components.
COLD WEATHER
PRECAUTIONS
The functional operation of somecomponents and systems can be affectedat temperatures below approximately-13°F (-25°C).
BREAKING-IN
Your vehicle requires a break-in period. Forthe first 1,000 mi (1,600 km), avoid drivingat high speeds, heavy braking, aggressiveshifting or using your vehicle to tow. Duringthis time, your vehicle may exhibit someunusual driving characteristics.
Ground Clearance
Since ground clearance is reduced, usecaution when approaching curbs or curbstops from the front and rear as vehicledamage may occur. Additionally, whencrossing speed bumps or driveway curbs,you should approach at a 45 degree angleto reduce the risk of vehicle damage.
DRIVING ECONOMICALLY
The following helps to improve fuelconsumption:
•Drive smoothly, accelerate gently andanticipate the road ahead to avoidheavy braking.
•Regularly check your tire pressures andmake sure that they are inflated to thecorrect pressure.
