Basic Fault Finding
Complex Faults
For detailed troubleshooting, always refer to:
-
Your vehicle handbook, or
-
A qualified mechanic or technician
If in doubt about your vehicle’s safety or roadworthiness, do not drive until it’s checked.
Complex faults involving electronic or engine management systems should always be handled by professionals, as tampering could void your warranty.
Remember: Prevention is better — and cheaper — than cure.
Regular maintenance keeps your vehicle reliable, fuel-efficient, and environmentally friendly.

Regular Maintenance
Regular maintenance ensures reliability and extends the life of your vehicle.
Air Filter
Replace the air filter at the intervals specified by the manufacturer — more often if driving in dusty conditions.
Overhead Camshaft Engines
If your vehicle uses a camshaft drive belt, replace it exactly at the recommended interval.
A broken timing belt can cause severe engine damage.
