🛡️ Safety Features

Active Features

Active Safety:

Generally basic by modern standards; features focus on robust mechanical systems for off-road traversal rather than electronic driver aids. Includes 4-wheel drive with locking differentials (often selectable/automatic).

Passive Features

Passive Safety:

Roll cage construction, reinforced body structure, seat belts. Airbags were not standard on early models but may be present on later civilian variants.

💡 Technology Features

Infotainment

Infotainment System:

Basic by modern standards. Primarily focused on functional gauges and controls. Optional aftermarket head units are common.

Driver Assistance

Driver Assistance Features:

None as standard. CTIS can be considered a primitive driver assistance system for adjusting tire pressure on the move.

Connectivity

Connectivity Features:

No integrated connectivity features in stock form. Relies on basic auxiliary inputs for audio on some models.

🔧 Maintenance

Service Intervals

Oil Change Interval:

Typically 3,000 - 5,000 miles or 6 months (refer to manual for precise intervals based on operating conditions).
