Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Check Transmission Fluid Level

Locate the transmission dipstick (usually found near the back of the engine).
Remove the dipstick, wipe it clean with a lint-free cloth, and reinsert it fully.
Remove the dipstick again and check the fluid level; it should be between the "full" and "add" marks.

3. Add or Replace Transmission Fluid (if necessary)

If fluid is low, add the appropriate type of transmission fluid (refer to the owner's manual for specifications).
If fluid is dirty or smells burnt, consider replacing it.
- Sub-steps:
  - Drain the old fluid using a fluid extractor or by removing the transmission pan.
  - Replace the transmission filter (if applicable).
  - Reinstall the pan and fill with new fluid.

4. Reset the Transmission Fluid Light

Turn the ignition key to the "ON" position without starting the engine.
Press the accelerator pedal fully three times within five seconds.
Turn the ignition to the "OFF" position.
Start the engine and check if the light has been reset.
