3-point front seatbelts with pretensioners and load limiters, 3-point rear seatbelts.
๐ก Technology Features
Infotainment
Audio System:
Base models typically featured an AM/FM radio with CD player. Higher trims offered upgraded audio systems with more speakers, and optional cassette players in earlier models. Bluetooth connectivity was not standard.
Driver Assistance
ABS Vdc:
Anti-lock Braking System (ABS) was widely available. Vehicle Dynamics Control (VDC) was introduced and became more prevalent on higher trims of the second generation, enhancing stability.
Connectivity
Oem Integration:
Limited by modern standards. Primarily focused on OEM audio system and climate control integration. The manual will cover diagnostic ports (OBD-II) for engine management systems.
๐ง Maintenance
Service Intervals
Oil Change Recommendation:
Every 3,750 miles or 6 months (severe duty) or 7,500 miles or 12 months (normal duty), depending on driving conditions and oil type used. Consult manual for specifics.
Timing Belt Replacement:
Typically every 105,000 miles or 105 months for the EJ25 engine. Critical maintenance item; failure can cause catastrophic engine damage. Includes replacement of water pump and tensioner/idler pulleys.
Spark Plug Replacement:
Every 60,000 miles for standard platinum plugs. Long-life iridium plugs may extend this interval.
Fluid Specifications
Engine Oil Specification:
API SN or higher, SAE 0W-20 or 5W-30 (check owner's manual for exact viscosity based on climate and engine type). For turbocharged models, synthetic 5W-30 is strongly recommended.
Coolant Specification:
Subaru Super Coolant (blue) or equivalent ethylene glycol-based coolant with Subaru's specific additive package. Typically a 50/50 mix with distilled water.
Brake Fluid Specification:
DOT 3 or DOT 4 brake fluid.
Known Issues
Head Gaskets:
While less common than in some earlier Subaru models, head gasket leaks can occur, particularly on high-mileage EJ25 engines. The manual will detail diagnosis and replacement procedures.
Turbocharger Issues:
For XT models, oil starvation due to improper maintenance or overheating can lead to turbocharger failure. Turbo oil feed/return lines are critical components to inspect and maintain.
Suspension Wear:
Sway bar end links, bushings, and strut mounts can wear over time, leading to clunks and poor handling. The manual will provide specs for replacement and alignment.
