Crash Test Data:
Varies by region and testing organization. Refer to specific regional safety reports for detailed ratings.
Braking System:
Front ventilated disc brakes, Rear disc brakes (solid or ventilated depending on model).
ABS:
Anti-lock Braking System (ABS) typically standard or optional on higher trims.
Airbags:
Driver and front passenger airbags standard on most models.
Audio System:
Factory-installed AM/FM stereo with CD player or cassette tape, typically with 4-6 speakers. Options for premium sound systems existed.
Cruise Control:
Optional feature on higher trim levels.
Auxiliary Inputs:
Limited by era; typically no factory-provided USB or Bluetooth connectivity, requiring aftermarket solutions.
Oil Change Interval:
Typically 5,000-10,000 km (3,000-6,000 miles) or 6-12 months, refer to manual for specific engine and oil type.
Timing Belt Or Chain:
V6 engines use a timing belt, typically replaced every 100,000-150,000 km (60,000-90,000 miles). Diesel engines often use timing chains.
Engine Oil Spec:
API CI-4 or CH-4 for diesel (e.g., 15W-40, 10W-30); API SG or SH for petrol (e.g., 10W-30, 5W-30). Refer to manual for exact viscosity and specification.
Transmission Fluid Type:
Dexron III (ATF) for automatic; GL-4 or GL-5 for manual transmission and transfer case (refer to manual for specific grades).
Coolant Type:
Ethylene glycol-based coolant, typically a 50/50 mix with distilled water. Refer to manual for specific type (e.g., long-life green or yellow).
Common Diesel Issue:
The 4JX1-TC engine is known for potential issues with the Isuzu's unique Electronic Control Unit (ECU) and diesel particulate filter regeneration if not properly maintained or used.
Common V6 Issue:
