Before You Drive: The Full Checklist

Category	Check	Why It Matters
Tires	Pressure, tread depth, spare	Blowouts are the #1 road trip emergency
Oil	Level and color	Engine damage on long drives if low
Coolant	Level and concentration	Overheating risk in summer and mountains
Brakes	Pad thickness, pedal feel	Long descents burn brakes fast
Battery	Voltage, terminal condition	Dead battery far from home = expensive tow
Lights	Headlights, brake lights, signals	Safety + ticket avoidance
Wipers	Blade condition, washer fluid	Rain on unknown roads needs clean glass
Belts & Hoses	Visual check for cracks/wear	A snapped belt can strand you

Tire Preparation

Check pressure on all 4 tires + the spare. Use the PSI on the door sticker, not the tire sidewall.

Check tread depth — Place a penny head-down in the grooves. If you can see the top of Lincoln's head, the tread is too worn.

Look for damage — Bulges, cuts, or nails in the sidewall mean replacement before the trip.

Fluid Levels

Engine oil — Should be between the min and max marks on the dipstick. Dark or gritty? Change it before the trip.

Coolant — Check the overflow reservoir when cold. Should be between marks.

Brake fluid — Low brake fluid can indicate worn pads. Check the reservoir under the hood.

Transmission fluid — Check with the engine running (in Park). Should be pink to light brown.

Windshield washer fluid — Fill it completely. You'll use more than you think.

Emergency Kit

Pack these in the trunk:

Jumper cables or a portable jump starter

Basic tool kit (wrench set, screwdrivers, pliers)

Flashlight with extra batteries

First aid kit

Tire inflator or portable compressor

Phone charger and backup cable

Run a Diagnostic Scan

Before any long trip, run a full OBD-II scan to check for pending codes. A code that hasn't triggered the check engine light yet (pending DTC) could escalate under heavy driving conditions.

ProHow Steer Helps

Steer's Pre-Drive Check automatically runs when you connect. It confirms all systems are stable, checks battery voltage, and flags any pending issues — giving you a green light or a warning before you hit the highway.
