Solution

1. Preparation

Gather necessary tools and replacement fluids.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Add Coolant

Locate the coolant reservoir (typically marked with a cap indicating coolant).
Check the level against the minimum and maximum markers on the reservoir.
If low, add the appropriate type of coolant (refer to the owner's manual for specifications).
Replace the cap securely.

3. Add Brake Fluid

Locate the brake fluid reservoir (generally near the back of the engine bay).
Check the level against the min/max lines.
If low, add the correct type of brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
Ensure the cap is tightly secured after adding fluid.

4. Add Transmission Fluid (if applicable)

Ensure the vehicle is on a level surface and the engine is running.
Locate the transmission dipstick (if present) or filler cap.
Remove the dipstick, wipe it clean, reinsert it, then remove again to check the level.
If low, add the specified transmission fluid through the filler neck.

5. Add Windshield Washer Fluid

Locate the washer fluid reservoir.
Check the level; if low, fill with suitable windshield washer fluid.
Replace the cap securely.
