The battery warning lamp flashes threetimes to confirm that the reset issuccessful.
Battery Management System (If
Equipped)
The system monitors battery conditionsand takes actions to extend battery life. Ifexcessive battery drain is detected, thesystem temporarily disables someelectrical systems to protect the battery.
Systems included are:
•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message may appear in the informationdisplay to alert you that battery protectionactions are active. This message is only fornotification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
After battery replacement, or in somecases after charging the battery with anexternal charger, the battery managementsystem requires eight hours of vehicle sleeptime to relearn the battery state of charge.During this time, your vehicle must remainfully locked with the ignition switched off.
Note:Prior to relearning the battery stateof charge, the battery management systemmay temporarily disable some electricalsystems.
Electrical Accessory Installation
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the battery negative post. Thiscan cause inaccurate measurements ofthe battery condition and potentialincorrect system operation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
Remove and Reinstall the Battery
Install a battery approved for use by ourspecifications. See Capacities andSpecifications (page 337).
To disconnect or remove the battery, dothe following:
1.Apply the parking brake and switch theignition off.
2.Switch all electrical equipment off, forexample lights and radio.
3.Wait a minimum of two minutes beforedisconnecting the battery.
Note:The engine management system hasa power hold function and remains poweredfor a period of time after you switch theignition off. This is to allow the system tostore diagnostic and adaptive tables.Disconnecting the battery without waitingcan cause damage not covered by thevehicle warranty.
4.Disconnect the negative battery cableterminal.
5.Disconnect the positive battery cableterminal.
6.Remove the battery securing clamp.
7.Remove the battery.
8.To install, reverse the removalprocedure.

TRACK USE - MACH 1
Operating at High Speeds andTrack Days
Your vehicle is capable of sustained highspeeds and track day driving.
Before operating your vehicle at highspeeds:
•Verify your tires have the correctpressures.
•Inspect wheels and tires for wear anddamage. Replace any damaged wheelsand tires.
•Check and set lug nut torque. SeeTechnical Specifications (page 336).
•Verify fluid levels for oil, coolant, brakeand hydraulic fluid. See Capacitiesand Specifications (page 337).
•Change the engine oil and replace theengine oil filter prior to use on the track.Change the engine oil and filter againafter every four hours of track time.Maintain the engine oil level at or nearthe max mark on the engine oil dipstick.See Engine Oil Check (page 262).
•Replace the brake fluid with freshMotorcraft/Ford DOT 4 LV HighPerformance Brake Fluid or other DOTcompliant fluid with a dry boiling pointgreater than 500°F (260°C) from asealed container. Do not use siliconeor DOT 5 brake fluids.
•If you are operating your Mach 1 on adrag strip, use drag strip selectabledrive mode in addition to using line lockand launch control to provide a specificset-up tuned for the quickest straightline elapsed times.
•If you are operating your Mach 1 on aroad course, use sport or trackselectable drive modes to provide aspecific set-up tuned for optimal shiftand suspension set-up that is tunedtowards handling prowess on closedcourse surfaces.
After operating your vehicle at high speedsor track day driving, do the following:
•Set the tire pressure to the properspecification.
•Check and set the lug nut torque. SeeTechnical Specifications (page 336).
•Check all fluid levels.
•Refer to the track maintenance intervalchart. See Normal ScheduledMaintenance (page 452).
•Check the front and rear wheelbearings for abnormal wear.
•Inspect brake caliper dust boots forabnormal wear.

Line Lock
Line lock is a feature intended for use attracks only and should not be used onpublic roadways. Use of this feature mayresult in significantly increased rear tirewear. It is intended to condition the reartires to maximize traction prior to track use.Line lock maintains brake force at the frontwheels, allowing the rear wheels to spinwith minimal vehicle movement.
This feature is located in the Track Appsmenu. Make selections through the 5-wayinformation display control and OK buttonlocated on the steering wheel.
Using Line Lock
There are three line lock stages:
•Initiated.
•Engaged.
•Off.
Initiating Line Lock
The initiation stage verifies that the vehicleis ready for line lock function, and confirmsdriver intent. Follow the prompts in theinformation display to initiate line lock.
The following conditions must be met toinitialize line lock:
•The vehicle is on a level surface.
•The engine is running.
•The vehicle is traveling less than25 mph (40 km/h).
•Selectable drive mode is not in wetmode (if equipped).
•There are no electronic stability controlfaults.
If you want to cancel line lock once it isinitialized, press the left informationdisplay control. Once initiated, line lock isprepared for activation and remainsinitiated up to 25 mph (40 km/h). If vehiclespeed exceeds 25 mph (40 km/h), line lockautomatically cancels.
Engaging Line Lock
Follow the prompts in the informationdisplay to engage line lock after it isinitialized. To engage, firmly apply thebrakes. Then press the OK button. Onceengaged, release the brake pedal. Thefront brakes remain applied and the rearbrakes release. At this point, theengagement timer is initiated and shownon the driver information display.
The following conditions must be met toengage line lock:
•The vehicle is on a level surface.
•The engine is running.
•The vehicle is stopped.
•The parking brake is not applied.
•The driver door is closed.
•The transmission is in a forward gear.
•Selectable drive mode is not in wetmode (if equipped).
•There are no electronic stability controlfaults.
•The steering wheel must be in thestraight ahead position.
Releasing Line Lock
While line lock is engaged, you can exit(release) the feature using the OK button.When you press the OK button, line lockreleases immediately and normal vehiclefunction resumes. When line lock engages,a countdown timer shows the remaining

Rear Gurney Flap
The rear Gurney flap must be removedfor on-road driving.
Your vehicle may include a removableGurney flap in the luggage compartment.The Gurney flap greatly enhances highspeed stability and performance on thetrack. It is recommended that you use theGurney flap at all tracks featuring highspeed corners and can be used at any trackregardless of cornering speeds.
You could benefit from the removal Gurneyflap to improve low speed balance onsmaller tracks with maximum corneringspeeds below 70 mph (112 km/h). Werecommend that you attach the Gurneyflap for all track events and carefullyassess both the vehicle's condition andyour capability before removal.
