1. Ensure the vehicle is parked on a level surface and the parking brake is fully applied.
2. Locate the handbrake lever. It's usually located between the front seats.
3. Lift the cover of the handbrake lever to expose the adjusting mechanism.
4. You'll see a nut or bolt that can be turned to adjust the handbrake cable tension. Use a suitable spanner or wrench to turn the nut or bolt.
5. Tighten the nut or bolt until the handbrake lever can be pulled up four clicks before it engages.
6. Test the handbrake by applying it and releasing it several times. Ensure it holds the vehicle securely and releases smoothly.
7. Lower the handbrake lever and replace the cover.
Remember, adjusting the handbrake is a safety-critical task. If you are unsure how to do it, it's best to have it adjusted by a qualified mechanic.
