Braking:

Front ventilated discs, rear solid discs. ABS (Anti-lock Braking System) was optional on some models and standard on later ones.

Restraints:

Three-point seat belts. Driver airbag became standard in 1990 for US models. Passenger airbag introduced later in the generation in some markets.

Structural Reinforcement:

Reinforced A-pillars and side sills for improved rollover protection.

💡 Technology Features

Basic AM/FM stereo with cassette player, often with 4 speakers. Optional CD players were available on later models or as dealer upgrades.

ABS Availability:

ABS was an optional feature on many NA models, becoming more common or standard in later years.

Early Tech:

As a 1990s vehicle, advanced connectivity features like Bluetooth or USB ports are not present. Features are limited to basic automotive electronics.

🔧 Maintenance

Oil Change Interval:

Typically every 5,000-7,500 miles or 6 months, whichever comes first. Consult manual for specific mileage based on driving conditions.

Timing Belt Interval:

The B6-ZE engine uses a timing belt. Replacement interval is generally around 60,000 miles or 5 years. This is a critical maintenance item.

Spark Plug Replacement:

Typically every 30,000 miles. Use of correct spark plug type (e.g., NGK BKR5E-11) is important.

Approximately 4.0 US quarts (3.8 L) with filter change. Use SAE 5W-30 or 10W-30 viscosity oil meeting API SG or higher specifications.

Coolant Capacity:

Approximately 5.0 US quarts (4.7 L) of 50/50 coolant/water mix.

Brake Fluid Type:

DOT 3 or DOT 4 (check specific year/manual for confirmation). Always use fresh, sealed fluid.

Rust Susceptibility:

Rocker panels, rear wheel arches, and chassis rails are prone to rust, especially in regions with salted roads.

Oil Cooler Seals:

Leaking oil cooler seals are a common issue, often resulting in oil puddles under the car.

Fuel Pump Reliability:

Older fuel pumps can become less reliable over time, potentially leading to starting issues or reduced performance.

Window Regulators:

The manual window regulators can become stiff or fail due to wear and tear.
