2023 FORD MUSTANG brake fluid

You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is noneed to stop your vehicle. You cancontinue to drive.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1.Stop your vehicle as soon as it is safeto do so. Fully apply the parking brake,shift into park (P) or neutral (N).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop afterseveral minutes, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.

AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer checkand change the transmission fluid at thecorrect service interval. See ScheduledMaintenance (page 449).
The automatic transmission does not havea transmission fluid dipstick.
Refer to your scheduled maintenanceinformation for scheduled intervals for fluidchecks and changes. Your transmissiondoes not consume fluid. However, if thetransmission slips, shifts slowly or if younotice a sign of leaking fluid, contact anauthorized dealer.
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
BRAKE FLUID CHECK
WARNING: Do not use any fluidother than the recommended brake fluidas this will reduce brake efficiency. Useof incorrect fluid could result in the lossof vehicle control, serious personal injuryor death.
WARNING: Only use brake fluidfrom a sealed container. Contaminationwith dirt, water, petroleum products orother materials may result in brakesystem damage or failure. Failure toadhere to this warning could result in theloss of vehicle control, serious personalinjury or death.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.
WARNING: The brake systemcould be affected if the brake fluid levelis below the MIN mark or above the MAXmark on the brake fluid reservoir.

1.Park your vehicle on a level surface.
2.Look at the brake fluid reservoir to seewhere the brake fluid level is relativeto the MIN and the MAX marks on thereservoir.
Note:If the brake fluid level is between theMIN and the MAX marks on the reservoir, itis acceptable.
Note:If the brake fluid level is below theMIN mark or above the MAX mark, haveyour vehicle checked as soon as possible.
Note:To avoid fluid contamination, thereservoir cap must remain in place and fullytight, unless you are adding fluid.
Only use fluid that meets ourspecifications. See Capacities andSpecifications (page 337).
Brake Fluid Service Interval
Brake fluid absorbs water over time whichdegrades the effectiveness of the brakefluid. Change the brake fluid at thespecified intervals to prevent degradedbraking performance.
For detailed interval information, seeScheduled Maintenance in your Owner'sManual or your local maintenance guide.
CLUTCH FLUID CHECK -
MANUAL TRANSMISSION
The clutch and brake systems share thesame fluid reservoir. See Brake FluidCheck (page 270).
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electricpower steering (EPS) system. There is nofluid reservoir to check or fill.
CHANGING THE 12V BATTERY
WARNING: Batteries normallyproduce explosive gases which cancause personal injury. Therefore, do notallow flames, sparks or lightedsubstances to come near the battery.When working near the battery, alwaysshield your face and protect your eyes.Always provide correct ventilation.
WARNING: When lifting aplastic-cased battery, excessive pressureon the end walls could cause acid to flowthrough the vent caps, resulting inpersonal injury and damage to thevehicle or battery. Lift the battery with abattery carrier or with your hands onopposite corners.

CHECKING THE WIPER
BLADES
Run the tip of your fingers over the edge ofthe blade to check for roughness.
Clean the wiper blades with washer fluidor water applied with a soft sponge orcloth.

Change the rear axle fluidEvery 500 mi (800 km)1
1 Change the fluid every 500 mi (800 km) or when a message appears in the informationdisplay stating that the axle fluid is over temperature.
Timing Chain
If you use your vehicle extensively at a racetrack or at high rpm, it is possible to exceedthe service life of the engine timing chain.A wrench indicator light illuminates whenit is time for you to replace your chain.Have your vehicle checked as soon aspossible.
Adjustable Camber Front StrutTop Mounts (If Equipped)
Your vehicle has adjustable strut mountswhich you can use to adjust the camber ofyour vehicle before and after a track eventto the specifications listed in the RoadCourse Alignment Recommendations tablepreviously shown.
Note:After your track day is complete,return your car to the street alignment andtire pressures.
Aerodynamics (If Equipped)
Adjustable Rear Wing
The rear wing generates aerodynamicdown-force at speeds greater than 50 mph(80 km/h).
Regularly inspect the rear wing panel andattachment points for damage orlooseness.
You can adjust the wing using the holepattern at the top of the stanchion.
Moving the wing up increases rear downforce and overall understeer. Moving thewing down decreases the rear down forceand overall understeer.
