Solution

1. Preparation

Gather necessary tools: a clean rag or paper towel for checking the oil dipstick.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Checking Engine Oil Level

Locate the engine oil dipstick, usually marked with a brightly colored handle.
Pull the dipstick out and wipe it clean with a rag or paper towel.
Reinsert the dipstick fully and then pull it out again to check the oil level.
The oil level should be between the minimum and maximum marks. If low, add the recommended oil type (refer to owner's manual).
Ensure the cap is securely replaced after checking.

3. Checking Coolant Level

Locate the coolant reservoir, typically a translucent plastic tank near the radiator.
Check the coolant level against the minimum and maximum markings on the side of the reservoir.
If the coolant is low, carefully remove the cap (only when the engine is cool) and add the appropriate coolant mixture (refer to owner's manual).

4. Checking Brake Fluid Level

Locate the brake fluid reservoir, usually clear and mounted near the back of the engine bay.
Visually inspect the fluid level against the minimum and maximum markings on the reservoir.
If fluid is low, add DOT 4 brake fluid (as specified in the owner's manual).

5. Checking Power Steering Fluid Level

Locate the power steering fluid reservoir, which may have a cap labeled "Power Steering Fluid."
Check the fluid level through the translucent reservoir or by removing the cap.
If low, add the specified power steering fluid (refer to owner's manual).
