Regular maintenance can help identify problems early, improve reliability, and reduce the risk of avoidable breakdowns.

This checklist provides general guidance only. The correct maintenance schedule for your vehicle is the schedule published by its manufacturer.

Before Every Trip

• Confirm that the windshield provides clear visibility
• Check that mirrors are correctly positioned
• Look for visibly damaged or underinflated tires
• Check for fresh fluid leaks under the vehicle
• Confirm that important warning lights turn off normally
• Listen for unusual noises after starting the engine
• Make sure cargo does not interfere with the driver

Monthly Checks

• Check tire pressure when the tires are cold
• Inspect tires for cuts, bulges, cracks, and uneven wear
• Check windshield-washer fluid
• Inspect exterior lights
• Check windshield wipers
• Look for visible battery corrosion or damage
• Inspect the parking area for new leaks

Engine Oil

Check the engine-oil level according to the procedure in the owner’s manual.

Use only an oil type and specification approved for the vehicle.

Change the oil and filter according to the manufacturer’s schedule or the vehicle’s maintenance-monitoring system.

Seek inspection when you notice:

• Low oil pressure warnings
• Repeatedly falling oil levels
• Visible leaks
• Burning-oil odors
• Unusual engine noise

Coolant

Check coolant only according to manufacturer instructions.

Do not open a hot pressurized cooling system.

Use the correct coolant specification. Mixing incompatible coolant types may cause problems.

Repeatedly low coolant, overheating, visible leaks, or steam should be investigated promptly.

Brake System

Have the brakes inspected according to the manufacturer’s schedule and whenever symptoms appear.

Warning signs include:

• Grinding or scraping sounds
• Longer stopping distances
• A soft or sinking pedal
• Pulling while braking
• Pedal or steering-wheel vibration
• A brake warning light

Tires

Regular tire maintenance may include:

• Checking pressure
• Inspecting tread depth
• Checking for uneven wear
• Rotating tires when recommended
• Checking wheel alignment when symptoms appear
• Replacing damaged or excessively worn tires

Use the pressure specified by the vehicle manufacturer rather than the maximum pressure printed on the tire sidewall.

Battery

Check the battery for:

• Corrosion
• Loose connections
• Cracks or swelling
• Slow engine cranking
• Repeated starting problems

Battery testing may be useful before extreme weather or a long trip.

Filters

Depending on the vehicle, filters may include:

• Engine air filter
• Cabin air filter
• Oil filter
• Fuel filter
• Transmission filter

Replacement intervals and accessibility vary. Follow the manufacturer’s maintenance schedule.

Belts and Hoses

Inspect accessible belts and hoses for:

• Cracks
• Fraying
• Glazing
• Swelling
• Leaks
• Loose or damaged connections

Timing-belt replacement intervals are especially important when the engine uses a scheduled replacement belt.

Transmission and Driveline

Transmission-fluid requirements vary significantly. Some vehicles have specific checking procedures, service intervals, or sealed systems.

Use only the correct fluid specification and follow manufacturer instructions.

Seek inspection for:

• Delayed engagement
• Harsh or slipping shifts
• Fluid leaks
• New whining or grinding sounds
• Transmission warning messages

Steering and Suspension

Have the system inspected when you notice:

• Pulling to one side
• Excessive bouncing
• Uneven tire wear
• Loose or unpredictable steering
• Clunking or knocking sounds
• A sudden change in steering effort

Lights and Electrical Equipment

Check:

• Headlights
• Brake lights
• Turn signals
• Hazard lights
• Reverse lights
• Interior warning indicators
• Horn
• Windshield-washer system

Every Six Months

Depending on use and manufacturer recommendations, review:

• Tire wear and rotation needs
• Brake condition
• Battery performance
• Wiper condition
• Exterior-light operation
• Visible belts and hoses
• Fluid levels and leaks
• Cabin and engine air filters

Annual Review

An annual review may include:

• Manufacturer-scheduled maintenance
• Brake and tire inspection
• Battery test
• Cooling-system inspection
• Suspension and steering inspection
• Air-conditioning performance
• Recall verification
• Emergency-kit inspection

Before a Long Road Trip

• Check tire pressure and condition
• Check the spare tire or tire-repair system
• Check engine oil and other accessible fluids
• Confirm that lights and wipers work
• Check battery condition
• Inspect for leaks
• Confirm that scheduled maintenance is current
• Carry emergency and roadside contact information
• Secure luggage and heavy items

Severe Driving Conditions

More frequent maintenance may be needed when the vehicle is regularly used for:

• Short trips
• Stop-and-go traffic
• Towing or heavy loads
• Dusty roads
• Very hot or cold conditions
• Mountain driving
• Commercial or ride-service use

Review the severe-service schedule in the owner’s manual.

Maintenance Records

Keep records of:

• Service dates
• Mileage or distance
• Parts and fluids used
• Receipts and warranties
• Inspection results
• Recurring symptoms

Organized records can help with troubleshooting, warranty claims, and vehicle resale.
