The Pretrip Checkup

Your vehicle will be where you spend the bulk of your time during your journey, so make sure all its functions are fine-tuned and operating at maximum performance levels.

Fluids. Check all levels: oil, coolant, brake, and windshield-washer fluids. Inspect power-steering and transmission fluid levels, if applicable. If you’re taking a long trip, schedule a service appointment to double-check these levels. (Read “How to Check Your Car’s Engine Oil.”)

Hoses. Squeeze hoses with your thumb and forefinger near clamps—that’s where they can be weakest from wear. Feel for soft or mushy spots. A good hose will be firm but bendable. Look for parallel cracks around bends; a hardened, glassy surface (which indicates heat damage); or abrasive damage. Have damaged hoses replaced.

Belts. Heat, oil, ozone, and abrasion can take a toll on belts. Look for cracks, fraying, and splits, as well as signs of glazing. Replace worn belts. (Read “How to Inspect Belts and Hoses.”)

Air filter. Remove the filter and hold it up to a strong light. If you don’t see light, the filter is dirty enough to need to be replaced. A clean air filter helps the engine run better.

Radiator. Look through the grill and be sure the radiator is clear of any obstructions.

Battery. Make sure the terminals and cables are securely attached, with no corrosion. If the battery has removable caps, check its fluid level—­especially in warmer climates. Top off as needed with distilled water. (See our car battery buying guide and ratings.)

Wipers. Based on CR tests, windshield wipers last about six months. If they’re a few months old, consider replacing them before a long trip. If the wipers are newer, clean the blades with washer fluid or glass cleaner.

Tires. Check the pressure on all tires, including the spare, before starting the trip. Use the pressure recommended by the vehicle’s manufacturer, which usually can be found on a front doorjamb and in the owner’s manual. Inspect tires for abnormal or uneven wear, cracks, cuts, and any sidewall bulges. Replace tires that are 10 years old or overly worn. Once underway, check the pressure only after the tires have cooled for 3 hours to get an accurate measurement. (See our tire buying guide and ratings.)

Brakes. You might need a comprehensive checkup if you apply the brakes and there are grinding noises, or unusual vibrations in the brake pedal or steering wheel, or if the vehicle pulls to one side.

Glove box. Be sure you have up-to-date registration and insurance paperwork.

Lights. Check exterior lights, including taillights, brake lights, turn signals, and fog lamps. Make sure lenses are clean, so the lights are as bright as possible.

Infotainment. Reduce distractions: Pair your phones and transfer your contact lists ahead of time. (Make sure the roadside-assistance number is programmed.) Confirm that any subscriptions for satellite radio, traffic services, and streaming music are up-to-date. Add radio presets and program all destinations before you hit the road.

Packing for a road trip

How to Pack Like a Pro

Don’t overload your car. Weight limits are listed on the driver’s doorjamb and in the owner’s manual; the figure is for the combined weight of passengers and cargo. Don’t exceed manufacturer recommendations, which vary widely. A Chevrolet Equinox has a 993-pound limit; a Honda Odyssey, 1,340 pounds; and a Buick Enclave, 1,623 pounds.

Stow the heaviest items low, particularly in SUVs. This keeps the center of gravity lower, reducing the chances of a rollover. Smaller items should be packed into duffel bags or safely tucked into storage areas. Strap larger items down with cargo anchors. Don’t place heavier items on top of the cargo pile, because they can become dangerous projectiles in a panic stop or a crash.

You could opt for a roof cargo carrier, but CR tests found that a cargo carrier atop a midsized sedan can reduce fuel economy by as much as 5 mpg.

Your Truly Complete Car Emergency Kit

Prepare for breakdowns and make sure you have these items onboard.

Phone charger. In addition to having on hand a charging cord and power adapter, carry a small battery-based charger in case your car’s battery dies.

Basic tools. Have standard and Phillips screwdrivers, pliers, and a compact socket set.

Warning light, hazard triangle, and/or flares. These can alert motorists to your presence along the side of the road.

Tire tools. If you don’t know how to change a tire, consider learning before the trip. You could pack an easier-to-use lug or torque wrench, as well as work gloves. A short wooden board (about a foot long) can be invaluable to stabilize a jack on soft dirt or mud. Many newer cars don’t have spare tires, so familiarize yourself with your car’s “mobility kit.” Know how to reach roadside assistance in case the tire can’t be easily replaced.

Flashlight. This or a head-mounted light can be especially helpful during nighttime breakdowns or tire changes.

Jumper cables or a jump-starter. Cables can be handy, but a paperback-sized jump-starter can get your motor running on its own. Plus, many can also be used to charge portable devices.

Reflective vest. This safety measure will make you more visible in the dark.

Fire extinguisher. Pack a compact dry-powder unit for fires fueled by solids and combustible liquids and gases (class ABC). Of course, the safest response may be to get passengers far away from the vehicle and call 911.
