🛡️ Safety Features

Ancap Rating Historical:

Models from this era often had varying safety ratings depending on market and specification. Early models may have had lower ratings compared to contemporary standards. Specific ANCAP (Australasian New Car Assessment Program) ratings would need to be researched for individual markets.

Braking System:

Front disc brakes, rear drum brakes common. ABS (Anti-lock Braking System) may be optional or standard depending on trim and market.

Airbags:

Driver and passenger airbags typically standard or optional depending on trim level.

💡 Technology Features

Audio System:

Basic AM/FM radio with CD player was common for these model years. Higher trims might have offered more advanced systems or optional premium audio.

ABS:

Anti-lock Braking System (ABS) available as optional equipment on many models.

Traction Control:

Traction control systems were less common in this segment during these years but may have been available on higher-spec variants.

Connectivity Options:

Limited connectivity by modern standards. Typically Bluetooth hands-free calling may have been an option on later models of this generation.

🔧 Maintenance

Oil Change Interval:

Typically 5,000 - 10,000 km or 6-12 months for diesel engines, depending on operating conditions. Manual will specify exact intervals and oil type.

Transmission Fluid Interval:

Manual transmission fluid changes typically every 40,000 - 60,000 km. Automatic transmission fluid changes are more frequent. Exact intervals will be in the manual.

Timing Belt Or Chain:

The 4JH1 and 4JJ1 engines use timing chains, which are generally designed to last the life of the engine, but tensioners and guides may require inspection. The C24SE and 6VE1 likely use timing belts which have specific replacement intervals (e.g., 80,000-100,000 km).

Engine Oil Spec Diesel:

API CF or CH-4 or CI-4 rated 15W-40 or 10W-30 low-ash diesel engine oil is common. Specific viscosity and API rating to be confirmed in the manual.

Transmission Fluid Manual:

GL-4 or GL-5 rated gear oil, typically SAE 75W-90 or 80W-90. Capacity and specific GL rating will be detailed.

Coolant Type:

Ethylene glycol-based coolant, typically a long-life formulation (e.g., OAT or HOAT). Capacity and color specification (e.g., green, red, blue) would be in the manual.

Diesel Injector Wear:

Common on older common rail diesel systems, can lead to rough running, poor starting, or reduced power.

Turbocharger Maintenance:

Requires regular oil changes with quality oil to prevent premature wear of the turbo bearings. Hot shutdown after heavy load can cause oil coking.

Suspension Bushings:

Wear on rubber bushings in suspension and steering components is common over time due to heavy use, leading to noise and imprecise handling.
