You're sitting at a stoplight. The sky is dumping that heavy, wet slush that makes every intersection feel like a skating rink. You look down at the center console of your Toyota Highlander and see it. The Snow Button. It’s been there since you bought the car, tucked away near the gear shifter or the terrain dial, depending on your model year. You press it. A little light pops up on the dash. But does it actually do anything? Or is it just a placebo to make you feel better while you’re sliding toward a mailbox?
Honestly, most people think the Toyota Highlander snow button is some kind of magical 4WD activator. It isn't. Your Highlander—if it’s the AWD version—is already smart enough to know when the wheels are slipping. What that button actually does is much more subtle, and if we're being real, much more boring. It changes how the transmission talks to the engine. It’s all about the "launch."
The Boring Science of Not Spinning Your Tires
When you’re on ice, your biggest enemy isn't the cold. It’s torque.
In normal driving mode, your Highlander wants to get moving efficiently, so it starts in first gear. First gear has the most "grunt." It’s designed to get two tons of SUV moving from a standstill. But on snow, that grunt is exactly what you don't want. If the engine sends too much power to the wheels too fast, they’ll just break traction and spin. You’ve seen it a thousand times: someone at a green light flooring it, tires screaming, car going nowhere.
The Toyota Highlander snow button tells the ECU (Electronic Control Unit) to skip first gear entirely. It forces the car to start in second gear. By starting in second, the wheels receive less immediate torque. The power delivery is dampened, sluggish, and lazy—which is perfect for a slippery surface. It’s basically the car’s way of making sure you don't accidentally floor it and turn your driveway into a luge run.
It also changes the throttle mapping. Have you ever noticed that when Snow Mode is on, the gas pedal feels kind of... squishy? Like you have to press it way further down to get the car to move? That’s intentional. Toyota engineers calibrated it so that even if you have a "lead foot," the car ignores your frantic inputs and accelerates with the grace of a tortoise.
Why the Year of Your Highlander Matters
Not all Snow Buttons were created equal. If you’re driving an older second-generation (2008-2013) or third-generation (2014-2019) Highlander, it’s usually a physical button labeled "SNOW." It’s a simple on/off switch.
On the newer fourth-gen models (2020 and later), Toyota got a bit fancier. Now, it’s often integrated into the Multi-Terrain Select (MTS) dial. You might have to toggle a switch or turn a knob to "SNOW" mode. In these newer versions, the car doesn't just mess with the gears; it also talks to the brakes. If the system detects one wheel spinning faster than the others, it’ll pulse the brake on that specific wheel to send power to the ones that actually have grip. It’s like a digital limited-slip differential.
Don't Leave It On All Winter
I’ve met people who turn the Snow Mode on in November and don't touch it until the first tulip pops up in April. Don't do that.
Using the Toyota Highlander snow button on dry pavement is a great way to make your car feel like a dog. Since you're starting in second gear every time, your 0-60 mph time goes from "respectable" to "is this thing broken?" More importantly, it can slightly tank your fuel economy. The engine has to work a bit harder to get the car moving from a stop in a higher gear. It’s not going to explode your transmission or anything—modern Toyotas are built like tanks—but it’s just unnecessary wear and a waste of gas.
Turn it off once you hit the main salted roads. If the asphalt is clear, let the car use first gear. It wants to.

The Hybrid Quirk
If you’re driving a Highlander Hybrid, things get weird. You don't have a traditional mechanical link between the front and back wheels like the gas version does. Instead, you have "Electronic On-Demand AWD." There’s a separate electric motor just for the rear wheels.
When you hit the snow button in a Hybrid, the car coordinates the gas engine and the electric motors to ensure the rear motor kicks in instantly. Usually, the Hybrid prefers to stay in FWD to save gas, but Snow Mode makes it much more aggressive about using that rear motor. It’s surprisingly effective. You get that instant electric torque, but the computer manages it so precisely that you rarely feel a slip.
Common Myths About Snow Mode
Let's clear some things up because there is a lot of bad info on the forums.
- "It makes the brakes better." No. It doesn't. Your Highlander has ABS (Anti-lock Braking System) regardless of what button you press. Snow Mode helps you go; it doesn't really help you stop. Physics still wins. If you're going 50 mph on black ice, the Snow Button is a spectator.
- "I don't need winter tires if I have Snow Mode." This is the most dangerous lie in the car world. All-season tires turn into hockey pucks when the temperature drops below 45°F. The Toyota Highlander snow button manages power, but it can't create grip where none exists. A FWD Highlander on Blizzaks will outdrive an AWD Highlander on "all-seasons" every single day of the week.
- "It locks the 4WD." It doesn't. Some Highlanders have an "AWD LOCK" button. That is different. The Snow Button is about transmission logic; the Lock button is about splitting power 50/50 between the axles.
Real World Scenario: The Steep Driveway
Imagine you're at a ski resort. The driveway is packed snow. You try to pull out, and the front wheels start to dig a hole. This is where you engage the Snow Button.
Instead of the "digging" motion, you'll feel the car sort of bog down. That’s good! That’s the second-gear start and the throttle dampening working. Keep a steady, light foot on the gas. If you have the newer MTS system, you might hear some clicking or grinding noises—that’s just the brakes grabbing the spinning wheels to find traction. It’s noisy, but it’s working.
What Experts Say
David Antle, a long-time technician who has worked on Toyota platforms for decades, often points out that Toyota’s VSC (Vehicle Stability Control) works in tandem with the snow settings. When Snow Mode is active, the VSC becomes "hyper-vigilant." It will cut engine power the moment it detects a lateral slide. This is why some people actually hate Snow Mode in deep, heavy snow—sometimes you actually need a little wheel spin to "churn" through the powder. If you’re truly stuck in a snowbank, Snow Mode might actually work against you by cutting power too much. In that specific, rare case, you might actually want to turn Traction Control off to let the tires dig.
The Actionable Takeaway
The Toyota Highlander snow button is a tool, not a savior. It’s best used for those first few seconds of movement.
- Press it when you are starting from a dead stop on slush, ice, or packed snow.
- Keep it on if you are driving through a residential neighborhood that hasn't been plowed yet.
- Turn it off once you reach a highway or any road where the pavement is visible.
- Combine it with a good set of dedicated winter tires if you live anywhere north of the Mason-Dixon line.
If you really want to master your Highlander’s winter performance, find an empty, icy parking lot. Turn Snow Mode on and try to "gun it." Then turn it off and try again. You'll feel the difference in the pedal response immediately. Understanding that "lag" is the key to not panicking when the car feels sluggish in a storm. It’s not losing power; it’s being smart so you don't end up in a ditch.
Check your owner's manual for the specific location of the button, as Toyota loves to move it every few years. In the 2024 models, it’s a toggle on the center console. In the 2017 models, it’s a small button near the cup holders. Wherever it is, now you know it’s just a "Second Gear" button with a better marketing name. Use it for the launch, then let the car do its thing.
To get the most out of your Highlander this winter, verify your tire pressure first. Cold air causes pressure to drop, and even the best Snow Mode can't compensate for an underinflated tire's poor contact patch. Set your tires to the PSI listed on your driver’s side door jamb, then let the electronics handle the rest.
