🛡️ Safety Features

Crash Test Results:

As a Kei car sold primarily in Japan, official international crash test ratings (e.g., Euro NCAP, NHTSA) might be limited. Consult market-specific safety reports or JNCAP for relevant data.

ABS:

Anti-lock Braking System (standard on most later models and optional on earlier ones).

E B D:

Electronic Brakeforce Distribution (often paired with ABS).

Airbags:

Driver and passenger airbags.

Body Reinforcement:

Reinforced body structure for enhanced safety, particularly important for a convertible.

💡 Technology Features

Factory Audio:

Basic factory-installed audio systems typically include radio, CD player, and speakers. Aftermarket upgrades are common.

Traction Control:

Traction Control System (TCS) may be present on some models or as an option, aiding in preventing wheelspin.

Aux Input:

Early models may not have standard AUX input; aftermarket solutions are available.

🔧 Maintenance

Engine Oil Change:

Typically every 5,000 - 7,500 miles (8,000 - 12,000 km) or 6-12 months, depending on driving conditions. Refer to manual for specific interval and oil type.

Spark Plugs:

Intervals vary based on spark plug type (standard, platinum, iridium). Typically 30,000 - 100,000 miles. Consult manual for recommended type and interval.

Timing Belt:

The JB-DET engine uses a timing chain, which generally requires no periodic replacement unless there are signs of wear or noise.

Engine Oil:

Refer to manual for specific viscosity grade (e.g., 0W-20, 5W-30) and API service classification.

Transmission Fluid Manual:

Manual transmission gear oil, typically GL-4 specification. Capacity approx. 2.0-2.5 liters. Check manual for exact type and quantity.

Transmission Fluid Automatic:

Automatic transmission fluid (ATF). Refer to manual for specific type (e.g., Dexron III or equivalent) and capacity.

Coolant:

Ethylene glycol based antifreeze, typically a 50/50 mix with distilled water. Refer to manual for specific type and capacity.

Brake Fluid:

DOT 3 or DOT 4 brake fluid. Check manual for exact specification.

Turbocharger Wear:

Like many turbocharged engines, the JB-DET can experience wear in the turbocharger over time, potentially leading to loss of boost or oil consumption. Regular oil changes and proper turbo cool-down practices are crucial.

Power Roof Actuators:

The hydraulic system for the retractable roof can develop leaks or the actuators may fail over time, requiring specialized repair or replacement as detailed in the manual.

Suspension Bushings:

Wear in suspension bushings can lead to increased noise, vibration, and compromised handling, especially on higher-mileage vehicles. Replacement procedures are covered.
