Manual Transmission:
Likely covers Ford's own 4-speed and 5-speed manual gearboxes (e.g., Type 9).
Automatic Transmission:
May cover Ford's C3 or C4 automatic transmissions, or potentially ZF automatics in higher-performance models.
Clutch System:
Procedures for clutch inspection, adjustment, and replacement.
Transmission Fluid Type:
Specific manual and automatic transmission fluid types (e.g., Mercon, Type-F, GL-4 gear oil) and capacities will be detailed.
Body Styles:
Hatchback (3-door and 5-door), Estate/Wagon, Saloon/Sedan (depending on market).
Wheelbase:
Approximately 2600 mm (102.4 inches) for most variants.
Overall Length:
Varies by body style, generally around 4350-4550 mm (171-179 inches).
Curb Weight:
Typically ranges from 1000 kg to 1250 kg (2200 lbs to 2750 lbs) depending on engine and specification.
Crash Test Information:
Limited independent crash test data for this specific year/region; manual will focus on vehicle structure and safety system components.

Anti-lock Braking System (ABS) as an optional feature, with diagnostic and repair information if equipped.
ECU Functionality:
For models with early fuel injection or electronic ignition, information on ECU testing and diagnostics may be included.
Oil Change Interval:
Typically every 5,000 - 10,000 miles (8,000 - 16,000 km) or 6-12 months, depending on driving conditions and oil type. Manual will specify exact intervals.
Tune Up Schedule:
Details on spark plug replacement, ignition timing adjustment, carburetor tuning (if applicable) at specified intervals.
Engine Oil Type:
Likely specifies various grades of SAE 30, 10W-30, 10W-40, or 5W-30 depending on engine and ambient temperature. API service classification will be specified.
Coolant Type:
