A weak 12-volt battery often reveals itself on the first freezing morning, not during the first major snowstorm. The same goes for washer fluid that freezes in the reservoir, tires that lose pressure overnight, and a defroster that can’t clear the windshield in time for an early commute. Catching these problems before cold weather hits is far easier than dealing with them on an icy road at 7 a.m.

Colorado Department of Transportation guidance calls for checking the battery, brakes, tire tread, coolant, lights, wipers, heater, defroster, windshield washer fluid, and fuel before winter travel. For Berthoud drivers, preparing early means you have time to address a developing issue before cold starts and icy roads turn it into something bigger.

Start with the Cold-Start Essentials

Cold temperatures put the highest demand on the systems that get your engine running and keep it protected after startup. A battery that turns the engine over slowly, requires multiple start attempts, or shows corrosion around the terminals needs attention before sustained freezing weather arrives.

Cold cranking amps measure a battery’s ability to deliver starting power at low temperatures, and a professional battery test can determine whether yours still has adequate capacity. You can spot loose terminal connections, visible corrosion, and a battery warning light on your own. An ASE-certified technician can test the battery, charging system, and starter with equipment that identifies whether the problem is the battery itself, the alternator, or another electrical component.

Engine coolant does more than prevent overheating. It also protects against freezing inside the engine and cooling system when temperatures drop. A coolant reservoir that looks full can still have a mixture that doesn’t meet your manufacturer’s specs. Watch for low coolant, leaks beneath the vehicle, a sweet smell after driving, or an overheating warning. Adding the wrong fluid or concentration creates its own problems, so testing and correcting the mixture should follow manufacturer specifications.

Check Tires & Brakes Before Snow Arrives

Tires and brakes determine whether your vehicle can actually use the traction it has. Before winter conditions arrive in Berthoud, inspect all four tires, not just the pair that powers the vehicle.

Measure Tread & Set Tire Pressure

Air pressure drops as temperatures fall, which is why a tire pressure warning can appear after an overnight cold snap. Check tire pressure when the tires are cold and use the pressure listed on the vehicle placard, typically found on the driver’s door jamb, not the maximum pressure printed on the sidewall.

CDOT identifies 3/16 inch as the minimum tire tread depth in its winter preparedness checklist. Look for uneven wear, sidewall damage, and tires approaching that threshold. Uneven tread affects handling even when the rest of the vehicle looks ready for winter.

Colorado may activate the Passenger Vehicle Traction Law during winter storms or hazardous road conditions. Requirements can vary based on vehicle type, tire designation, tread depth, and traction devices, so check current conditions before traveling. CDOT recognizes winter tires, all-weather tires, and mud and snow tires as acceptable options, but warns against installing winter tires only on the front axle, which can increase the risk of fishtailing.

Don’t Ignore Brake Changes

A firm, predictable brake pedal matters even more on slick pavement. Pulling during braking, vibration, grinding, a soft pedal, or a brake warning light are all reasons to schedule an inspection rather than wait to see if the problem worsens. A technician can inspect brake pads, rotors, fluid condition, and related components that simply aren’t visible during a driveway check.

Make Visibility & Defrosting Reliable

Clear glass and working lights are basic winter safety equipment. A few minutes spent clearing the vehicle before departure beats trying to compensate for limited visibility once you’re already moving.

Winter Washer Fluid
Winter windshield washer fluid is formulated for freezing conditions. Fill the reservoir with a winter-rated product before temperatures drop, and don’t dilute it with water unless the product instructions specifically allow it.

Wiper Blade Condition
Streaking, skipping, chattering, or torn rubber leaves moisture and road grime in the driver’s line of sight. Lift wipers away from an icy windshield before running them. Frozen blades can tear the rubber or strain the wiper motor.

Defroster Performance
The front defroster should clear fog and frost from the windshield; the rear defroster should clear its heating grid evenly. Weak airflow, unusual odors, or a windshield that stays fogged can point to a heating, ventilation, or air conditioning issue that needs diagnosis.

Full Vehicle Clearance
Remove snow and ice from all windows, mirrors, headlights, brake lights, turn signals, the roof, and the hood. Snow left on the roof can slide forward during braking and cover the windshield, and covered lights make it harder for other drivers to see you.

Also check that floor mats are locked into their proper retainers. A loose mat can interfere with the accelerator or brake pedal, a preventable hazard when road conditions already demand careful control.

Keep a Winter Emergency Kit in the Vehicle

A winter emergency kit won’t prevent every breakdown or weather delay, but it can make a roadside stop safer and more manageable. Keep it somewhere accessible rather than buried under heavy cargo, and review it at the start of each season to replace expired supplies, confirm the flashlight works, and make sure water and medications are suitable for the temperatures your vehicle may see.

Useful winter supplies include:

• Visibility tools: Ice scraper, snow brush, flashlight, and reflective warning devices
• Starting support: Jumper cables or a charged jump pack
• Warmth supplies: Blankets, gloves, hats, and extra warm clothing
• Basic necessities: Drinking water, first aid supplies, and any needed medications
• Traction equipment: Compact shovel, traction aid, and tire inflation or repair equipment appropriate for your vehicle
• Roadside items: Tow strap and phone charging cable, when appropriate for your travel plans

A Simple Berthoud Morning Routine

Small checks are easiest to complete when they follow the same order every day. This routine helps you catch a concern before pulling out of the driveway.

The Night Before
Park with enough fuel for the next trip, confirm you have winter washer fluid, and put the scraper and brush somewhere you can reach them quickly. If the tire pressure warning has appeared recently, check the tires before morning rather than assuming the warning will clear on its own.

The Startup Check
Listen for slow cranking, watch for dashboard warning lights, and let the defroster begin clearing the windshield before you leave. If the vehicle loses coolant, struggles to start, or can’t defrost adequately, don’t put off an inspection before a longer winter drive.

The Safe Departure Check
Before leaving, clear all snow and ice completely, verify that headlights and brake lights are visible, and check mirrors and windows from the driver’s seat. As you start driving, pay attention to pulling, vibration, grinding, or any change in brake pedal feel.

Winter preparedness comes down to starting reliably, stopping predictably, seeing clearly, and having what you need if conditions change. If a slow crank, warning light, coolant loss, tire concern, or brake issue needs a closer look, our ASE-certified technicians at Christian Brothers Automotive can inspect your vehicle and walk you through the findings in plain language.
