Safe Driving Tips for Your Lexus in Snow Rain and Heat

Thousands of weather-related crashes happen every year in the United States. Your Lexus comes with advanced safety systems and all-weather capabilities, but you need to know how to use them properly. Our team at Lexus of Southampton will walk you through how to handle snow, rain, and brutal heat so you can drive with confidence no matter what Long Island weather throws at you.

Preparing Your Lexus for Snowy Conditions

If you drive your Lexus in winter road conditions, the RX 350 has an Active Torque Control all-wheel-drive (AWD) system that automatically distributes engine power between the front and rear axles using sensor data. The NX 350 takes a different approach with full-time AWD that can shift power distribution from 75% in the front and 25% in the rear to an even 50/50 split when things get slippery. Trail Mode optimizes the AWD system for loose surfaces, moving power away from spinning wheels to ones that can grip the road.

Before winter, you need to get your Lexus ready for the change of seasons. Battery problems are a prime cause of winter breakdowns. If your battery voltage drops below 12.4 volts, it's time for a replacement. Use the penny test on your tires to check for at least 4/32 inch of tread depth. Add 3-5 psi to your tire pressure for winter driving, but be careful not to exceed your tires’ recommended maximum cold-weather tire pressure. Braking distances can be 3-4 times longer on snow and ice, and be sure your coolant has a 50/50 mix of antifreeze and water to keep your engine from freezing up.

It's also a great idea to have a winter emergency kit in your vehicle. Include warm items such as blankets, mittens, socks, hats, hand warmers, winter boots, and a sleeping bag. Vehicle accessories should include jumper cables, an ice scraper, a snow brush, a small folding shovel, and tire chains if you're heading to the mountains. Add a container of sand or nonclumping cat litter for traction, plus a flashlight with extra batteries, a first-aid kit, and bottled water.

Navigating Your Lexus Through Heavy Rain

Rain is more dangerous than you might think. Rain and mist conditions account for 77% of all weather-related crashes. The stability systems in your Lexus work overtime in these conditions. Tire condition is crucial when the road gets wet — the faster you go, the less grip your tires can have on the pavement. Wet roads can double how long it takes to stop compared to dry pavement, and worn tires can cause you to lose control at speeds that normally feel safe.

Smart wet-weather driving means adjusting your approach. Slow down and leave at least three seconds between you and the car ahead — more if it's really coming down. Turn on your headlights when it's raining, not just so you can see better but so other drivers can spot you through the spray and glare. If you start hydroplaning, keep the steering wheel straight and ease off the gas until your tires find the road again.

Managing High Temperatures and Intense Sunlight With Your Lexus

Summer heat is no joke for your Lexus. High temperatures make your oil thin out when your engine needs the most protection. Heat also speeds up oil breakdown, creating sludge that can clog oil passages and cause engine damage. Your cooling system works overtime during hot weather, so proper coolant levels are vital to avoid getting stuck on the side of the road with steam pouring from your hood.

Your air-conditioning (AC) system gets used heavily during summer heat waves. AC can eat up your engine's power, which means your cooling system has to work harder. Keep up with maintenance such as checking refrigerant levels, swapping out cabin air filters, cleaning the condenser coils, and getting professional service every two years or 30,000 miles. Watch your tire pressure, too — every 10 degrees of temperature change moves tire pressure about 2 psi. Don't let air out of warm tires to match the pressure recommendation, though. Hot tires normally run 10-20 psi higher, and that's perfectly normal.

Your car's interior takes a beating from summer heat. Parked cars can reach 130 degrees inside during summer, which dries out and cracks leather seats, fades fabric colors permanently, and warps dashboard and trim pieces, potentially affecting your vehicle's resale value. UV-blocking window film can stop up to 99% of harmful rays while keeping your interior cooler. Professional detailing every 4-6 months helps protect your investment, too.

Your Lexus gives you major advantages with its safety features and AWD systems, but these work best when you keep up with maintenance and stay alert when conditions change. Your brakes are your best safety feature for controlling your car in any weather, so make sure to have them checked regularly. AWD may give you confidence, but smart preparation and defensive driving are the real foundation for safe driving year-round.
