Seatbelt pre-tensioners (driver side) standard on later models.
Audio:
Factory fitted Clarion or Alpine audio systems with cassette player and radio. Optional CD changer in later models.
Climate Control:
Automatic climate control system with cabin air filtration on higher specification models.
Cruise Control:
Standard on most models, electronic speed control.
Trip Computer:
Basic trip computer functions (average speed, fuel consumption, distance to empty) available on later models.
Phone:
Some later models offered integrated car phone systems (rare and dated technology now).
Oil Change:
Typically every 6,000-10,000 miles or 12 months. Refer to specific service schedule for exact intervals.
Major Service:
Includes replacement of spark plugs, fuel filters, coolant, and inspection of belts, hoses, and suspension components, usually around 40,000-60,000 mile intervals.
Engine Oil:
API SG or SH, SAE 10W-40 or 10W-50 (check owner's manual for precise grade and capacity).
Coolant:
Ethylene Glycol based, typically a 50/50 mix with distilled water. Jaguar specific coolant may be recommended.
Transmission Fluid:
ZF TE-ML 14A specification Dexron II or equivalent (check specific manual for Dexron III compatibility).
Brake Fluid:
DOT 3 or DOT 4 (check manual). Fluid should be replaced every 2 years due to hygroscopic nature.
Electrical:
Wiring harness degradation ('curing' issue), central locking problems, instrument cluster failures (JAGUAR's notorious 'peelers').
Suspension:
Hydraulic suspension fluid leaks (self-levelling system), worn suspension bushings.
Engine:
Head gasket issues on early 3.2L models, oil leaks from crank seals, timing chain wear on high mileage engines.
Bodywork:
Corrosion, particularly around wheel arches, sills, and boot lid. Leaks from sunroof seals.
Legacy:
Jaguar has a long history of producing elegant, high-performance luxury saloons, building on models like the Mark II and XJ series.
Xjs Influence:
The XJ40 shared some design cues and engineering principles with the XJ-S sports car.
Production Years:
1986-1994
Manufacturing Location:
Coventry, England
Vin Period Coverage:
The provided VIN range (687219-708757) typically covers models from the mid-to-late production years of the XJ40, likely from around 1990-1993, depending on specific build dates.
General:
While specific awards for the XJ40 are less documented than its predecessors, it was generally well-received for its comfort, luxury, and performance, solidifying Jaguar's position in the luxury car market.
Reliability Perception:
Reputation for luxury and refinement, but often perceived as requiring more diligent maintenance compared to some German rivals, particularly concerning its electrical systems.
