Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery before beginning any electrical work.

2. Address Engine Oil Issues

Remove the oil dipstick and wipe it clean.
Insert the dipstick back into the tube and remove it again to check the oil level.
If low, add the appropriate type of engine oil (consult owner's manual for specifications).
If oil is dirty or contaminated, drain the old oil and replace it with fresh oil.

3. Coolant Level Check

Open the hood and locate the coolant reservoir.
Check the coolant level against the markings on the reservoir.
If low, add a 50/50 mixture of coolant and distilled water, ensuring the engine is cool.
Inspect hoses for leaks or damage and replace if necessary.

4. Battery Inspection

Ensure the battery terminals are clean and tightly connected.
Use a multimeter to check the battery voltage (should be around 12.6 volts when fully charged).
If the voltage is low, consider charging or replacing the battery.

5. Brake Fluid Check

Locate the brake fluid reservoir and verify the fluid level.
If low, add the appropriate brake fluid type (consult owner’s manual).
Inspect for leaks in brake lines or other components.
