When it comes to adventure-ready vehicles, few brands carry the same reputation as Subaru. With symmetrical all-wheel drive, rugged suspension setups, and a loyal following of outdoor enthusiasts, models like the Outback, Forester, and Crosstrek are staples on highways, backroads, and everything in between. But before you hit the open road—especially for longer journeys across state lines or into remote areas—your Subaru deserves more than a casual glance under the hood. 

Even if it’s been running smoothly around town, extended drives with higher speeds, varied terrain, and heavier loads can stress components in ways everyday commutes don't. Preparing your Subaru with a targeted service checklist will help keep your focus on the destination—not on dealing with unexpected breakdowns.

Oil, Fluids, and Filters

Start with the essentials: an oil and filter change. Even if you’re a bit early for your scheduled interval, doing this before a long trip is a smart move. Highway driving, especially in warm weather or steep terrain, puts extra heat on your engine—and turbocharged models like the Outback XT or WRX benefit greatly from clean oil to protect turbo components.

In addition to oil, check and top off the following:

• Coolant: Make sure it’s at the right level and still clean. Discoloration could mean it’s time for a flush—or worse, a small leak.
• Brake Fluid: Dark or cloudy fluid may have absorbed moisture, which compromises braking performance. Subaru recommends flushing it every 2–3 years.
• Windshield Washer Fluid: Keep it topped off, especially if your route includes rural highways, changing weather, or bug-heavy regions.
• Transmission Fluid: While CVTs don’t need frequent changes, an inspection for leaks or burnt-smelling fluid is smart before long trips.

Don’t forget about filters. A dirty engine air filter can reduce fuel efficiency—especially at higher altitudes. If it hasn’t been changed in 15,000 miles, replace it. A cabin air filter swap also improves HVAC performance, keeping the air clean and your focus sharp over long hours behind the wheel.

Tires: Pressure, Tread, and Age

Your tires are your only point of contact with the road, and in an all-wheel-drive Subaru, their condition affects more than just ride quality—it can impact your entire drivetrain.

• Tire Pressure: Set all four tires (and your spare) to Subaru’s recommended PSI—measured while cold. Low pressure can lead to overheating and blowouts during long stretches.
• Tread Depth: You want at least 4/32" of tread for dry conditions, and 6/32" if you're expecting rain or snow.
• Tire Age: Even if they look fine, tires older than six years can be compromised. Rubber dries out, increasing the risk of cracking or failure at highway speeds.
• Rotation and Balance: If you haven’t rotated your tires in the last 7,000 miles, do it now. It’ll help with even wear and reduce vibrations.

Have your service tech look for signs of uneven tread wear, punctures, or sidewall damage—issues that become much riskier with extra miles and cargo.

Brakes and Suspension

Heading into hills, stop-and-go traffic, or long descents? You’ll want to know your brakes are up to the challenge.

Ask your technician to check:

• Pad thickness
• Rotor condition (check for scoring, warping, or rust)
• Brake fluid moisture content
• Caliper operation and guide pins

If you’ve noticed any vibration, soft pedal feel, or pulling while braking, don’t wait—get it looked at before your departure.

Suspension also plays a key role in both comfort and control. Subaru’s long-travel struts and bushings absorb road imperfections, but when worn, they can create sway, nose-diving, or poor high-speed stability—especially when loaded with passengers and gear.

Battery and Electrical System

A weak battery may get you to work, but it could leave you stranded at a rest stop. Have yours load-tested before heading out.

Warning signs of a failing battery include:

• Sluggish cranking
• Dim headlights at idle
• Flickering interior lights
• Corroded terminals

Modern Subarus rely heavily on electrical systems—EyeSight, infotainment, power accessories—and long drives demand consistent voltage. Also double-check defrosters, seat heaters, and backup cameras, especially if traveling through cold or high-altitude areas.

Visibility: Lights, Wipers, and Glass

Good visibility is non-negotiable on the road. Before you go:

• Test all headlights, taillights, brake lights, fog lights, and turn signals. A burned-out bulb can compromise safety—and draw attention from law enforcement.
• Replace wiper blades if they streak, chatter, or skip. Visibility can drop fast in fog or rain.
• Clean your windshield, inside and out. It’s a small step that makes a big difference over long drives.

Roof Racks and Towing

Subaru owners love their roof racks—but double-check yours before loading it up.

• Ensure rails and crossbars are torqued correctly
• Test your cargo box, kayak mount, or bike rack for shifting at speed
• Stay within Subaru’s roof weight limit, usually 150–176 lbs including the rack

If towing, confirm the following:

• Proper tongue weight and load balance
• Secure light connections
• Functioning trailer brakes (if applicable)
• Safe tire condition on the trailer itself

Overloading or improper towing stresses your drivetrain and can lead to overheating—especially on steep grades or during summer travel.

Navigation and Infotainment

Before you leave, make sure your tech is up to the task:

• Update maps via USB or Wi-Fi
• Test Bluetooth pairing and audio playback
• Download offline maps if you’ll be in remote areas
• Double-check that your emergency contact settings are current in Starlink

If your Subaru is equipped with EyeSight, make sure the stereo cameras are clean and unobstructed. A malfunction here could disable adaptive cruise, pre-collision braking, and lane assist features—something you don’t want to discover after you’ve already hit the road.

Don’t Forget the Essentials

A small emergency kit can make a big difference:

• Jumper cables or a portable jump starter
• Tire inflator or sealant
• Flashlight with extra batteries
• Blanket and first-aid kit
• Bottled water and non-perishable snacks
• Charging cords and adapters for all devices

Your Subaru was built for the road. With a bit of preventative care, it will reward you with comfort, control, and peace of mind—whether you're cruising highways, navigating campgrounds, or venturing into the unknown. Road trips are about the memories—not the mishaps. Prep accordingly, and your Subaru will do what it does best: take you there and back again.
