Remote Rev lets equipped cars command engine speed from the remote control when the car is in park and the engine, oil, coolant, catalyst, key, and range conditions are satisfied.
S650
2025 Mustang Owner Guide
S650 cars have the richest hidden-feature set on the site: Remote Rev, passive key backup, mechanical decklid access, Track Apps, Line Lock, Drift Brake on equipped cars, and software-heavy recall/service considerations.
Tips, Tricks & Emergency Access
The passive key backup position is in the center console storage compartment under the plastic mat; place the key buttons-up with the unlock button facing forward, then press the brake and push-button start.
If the decklid will not open because the battery is discharged, pull the rear left-side seatback cushion aside, insert the mechanical key blade into the key slot, and turn it to release the latch.
The fuel filler funnel is stored under the luggage-compartment floor. Use it when adding fuel from a portable container.
Track Apps include acceleration timer, brake performance, lap timer, launch settings, performance shift indicator, Line Lock, launch control, rev match, and Drift Brake where equipped.
Line Lock is for track use only; it maintains front brake force so the rear tires can spin, and Ford warns it can significantly increase rear tire wear.
The available drift brake is also for track use only. It enables rear-tire lockup for drift maneuvers and automatically enables track mode when switched on.
First Things To Do
- Test both key fobs, locate the mechanical key blade, and practice the passive key backup slot procedure.
- Locate the decklid dead-battery release path, fuel filler funnel, tire mobility/spare equipment, wheel lock key, and jack points.
- If equipped, try Remote Rev only in a safe open area after the car reaches the required temperature conditions.
- Review Track Apps, drive modes, Line Lock, Drift Brake, launch control, and rev match settings before any track day.
- Run the VIN through Ford and NHTSA recall lookups; 2024-up Mustang recall coverage is VIN-specific and can include software, lighting, brake, fuel, suspension, camera, and wiper campaigns.
- Baseline battery health, tire pressures, brake fluid, coolant, oil, differential leaks, and software/update status after purchase.
- If tracking the car, follow Ford's track-use maintenance guidance instead of the normal commuting schedule.
Buyer Checks
Check VIN recall status before delivery and verify any completed recall repair invoices; do not assume another 2024-2026 car's recall list matches this car.
Inspect front splitter, undertray, rocker pinch welds, wheels, tires, brake rotors, calipers, and rear quarters for track or curb damage.
Verify GT, EcoBoost, Dark Horse, GTD, Performance Package, active exhaust, MagneRide, Recaro, and drift-brake claims with window sticker, VIN, equipment, and software menus.
Scan for OBD-II faults/readiness and inspect for tune, emissions, intake, exhaust, wheel/tire, or suspension modifications that could affect warranty or drivability.
Test every electronic feature before signing: cluster, cameras, drive modes, active exhaust, keyless entry, trunk release, software updates, and infotainment reset from the prior owner.
On manual cars, inspect clutch feel, hydraulic line condition, gear engagement, launch-control use evidence, and any signs of overheated driveline parts.
