New York winters can bring freezing temperatures, snow, ice, and changing road conditions, making seasonal vehicle preparation especially important. Checking your INFINITI's battery, tires, fluids, brakes, wipers, and other key components can help prepare your SUV for colder weather and winter driving.
At INFINITI of Smithtown, we help drivers throughout Smithtown, Nesconset, Lake Grove, and Long Island prepare their INFINITI SUVs for the winter season. Contact us to discuss winter maintenance, recommended service, or any concerns about your vehicle before temperatures drop, and visit our dealership to have your INFINITI inspected and serviced by our team.
1. Check Your INFINITI Battery Before Temperatures Drop
Cold weather puts additional demands on a vehicle's battery. INFINITI's winterizing guidance notes that cold temperatures can significantly reduce battery cranking power, making a weak battery more likely to cause starting problems.
This makes an INFINITI battery cold weather inspection especially useful before the temperature consistently falls below freezing.
Look for:
- Slow or hesitant engine cranking
- Corrosion around battery terminals
- A battery approaching the end of its service life
- Electrical accessories behaving unusually
- Warning lights related to the charging system
Having the battery tested before winter can identify a potential problem before it becomes a no-start situation on a cold morning.
2. Check Tire Pressure More Frequently
One of the simplest ways to winterize your INFINITI SUV is to monitor tire pressure regularly. Cold temperatures cause the air inside a tire to contract, which lowers pressure. AAA notes that tire pressure can decrease by approximately 1 PSI for every 10-degree Fahrenheit drop in temperature.
That means a major temperature swing can turn a previously correct tire pressure into an underinflated tire.
During winter:
- Check tire pressure when the tires are cold
- Follow the pressure listed on the vehicle's door-jamb label or owner's manual
- Check all four tires
- Inspect for visible damage or uneven wear
- Do not use the number molded into the tire sidewall as the normal inflation target
Correct tire pressure supports handling, braking, tire life, and fuel efficiency.
3. Evaluate Your Tires for New York Winter Driving
Tire condition matters even more when roads are wet, snowy, or icy. INFINITI's owner information recommends all-season or mud-and-snow tires for snowy and icy conditions rather than summer tires.
AAA also notes that winter tires use specialized rubber compounds and tread designs that remain more pliable in freezing conditions and can provide improved traction on snow and ice.
If your INFINITI SUV is equipped with worn tires, winter is not the time to overlook them.
Inspect:
- Tread depth
- Uneven wear
- Cracks or visible damage
- Tire age
- Correct tire size
- Proper inflation
- Matching tire specifications
If you are considering winter tires, check the recommendations for your specific INFINITI model and configuration.
4. Inspect the Cooling System and Antifreeze
Your cooling system remains important during winter even though the vehicle is no longer dealing with summer heat.
INFINITI recommends checking antifreeze when temperatures are expected to drop below 32 degrees Fahrenheit.
Before winter, check:
- Coolant level
- Evidence of coolant leaks
- Condition of hoses
- Correct antifreeze protection
- Service history
Do not open a hot cooling system. If you are unsure about coolant condition or the correct procedure, have an INFINITI technician inspect it.
5. Replace Worn Wiper Blades and Use Winter Washer Fluid
Snow, road spray, salt, and freezing precipitation can quickly make visibility a challenge.
Wiper blades that already leave streaks or skip across the windshield may perform poorly when dealing with ice and slush. Replace worn blades before the season becomes severe.
You should also keep the windshield washer reservoir filled with fluid rated for winter temperatures. AAA recommends using washer fluid designed to remain effective below freezing, since some conventional fluids can freeze in colder conditions.
Keep an ice scraper and snow brush in your INFINITI as well.
6. Inspect Brakes, Suspension, and Steering
Winter driving places a premium on predictable braking and handling. Before the season, have your brakes, suspension, and steering components inspected if they are due for service or showing signs of wear.
Pay attention to:
- Brake pad thickness
- Brake rotor condition
- Brake fluid condition
- Steering response
- Suspension noises
- Uneven tire wear
- Pulling to one side
For an INFINITI SUV, routine inspections are particularly useful before winter road conditions become more demanding.
7. Check Your Fluids and Maintenance Schedule
Fluids play an important role in cold-weather operation. Engine oil, coolant, windshield washer fluid, brake fluid, and other vehicle fluids should be checked according to the manufacturer's maintenance recommendations.
INFINITI's maintenance resources provide model-specific service schedules, including maintenance items for the 2026 QX60 such as engine oil and filter, tires, brake components, coolant, and other systems.
Do not automatically change oil viscosity based only on the weather. The correct oil specification depends on the specific engine and vehicle. Follow the owner's manual and INFINITI's recommendations rather than choosing a viscosity solely because temperatures are falling.
8. Build a Winter Emergency Kit
Even a well-maintained INFINITI can encounter unexpected road conditions. Keeping basic winter supplies in your SUV can make an unexpected delay more manageable.
Consider carrying:
- Ice scraper and snow brush
- Flashlight
- Gloves
- Blanket
- First-aid kit
- Jumper cables or an approved jump starter
- Small shovel
- Extra windshield washer fluid
- Drinking water
- Basic emergency supplies
INFINITI's owner information specifically recommends carrying winter equipment such as an ice scraper, shovel, and extra washer fluid.
What About Winter Driving in a QX60, QX65, or QX80?
Different INFINITI SUVs can have different tire, drivetrain, and maintenance requirements. An AWD-equipped SUV can provide additional traction, but all-wheel drive does not eliminate the need for appropriate tires or careful winter driving.
The QX60, QX65, and QX80 can all benefit from the same basic winter preparation principles:
- Maintain correct tire pressure
- Inspect tires before winter
- Keep the battery in good condition
- Check coolant protection
- Maintain clear visibility
- Keep up with scheduled service
- Carry appropriate emergency equipment
The QX65, for example, is available with all-wheel drive, while the QX60 lineup includes both FWD and AWD configurations depending on trim.
How Can an INFINITI Service Team Help With Winter Preparation?
A professional inspection can make winter preparation easier, particularly if you are unsure about the condition of your battery, brakes, tires, fluids, or other components.
INFINITI of Smithtown serves drivers throughout Smithtown, Nesconset, Lake Grove, and nearby Long Island communities. Our service team can help identify maintenance items that should be addressed before winter conditions arrive.
What Winter Maintenance Should I Do on My INFINITI SUV?
Start with the battery, tires, tire pressure, coolant, windshield washer fluid, wipers, brakes, and scheduled maintenance. Check your owner's manual for model-specific requirements.
How Does Cold Weather Affect My INFINITI's Battery?
Cold temperatures reduce battery cranking power, which can make a weak or aging battery more difficult to start. Having the battery tested before winter can help identify potential problems.
Should I Switch to Winter Tires for a New York Winter?
Winter tires can provide improved traction in freezing, snowy, and icy conditions because their rubber compounds and tread designs are engineered for cold-weather use. INFINITI also recommends appropriate all-season or mud-and-snow tires for snowy and icy conditions rather than summer tires.
How Often Should I Check Tire Pressure in Cold Weather?
Check tire pressure regularly when the tires are cold, especially when temperatures change significantly. AAA notes that pressure can fall by roughly 1 PSI for every 10-degree Fahrenheit drop.
Does INFINITI Recommend a Specific Winter Oil Viscosity?
Use the oil viscosity and specification listed for your particular INFINITI engine in the owner's manual or maintenance information. Do not select an oil viscosity solely because the weather is colder.
