Jeep Grand Cherokee Snow Driving: How to Use Quadra-Trac in Winter
Your 2020 Jeep Grand Cherokee is ready for winter — but are you using its full potential?
If you own a Grand Cherokee, you already know it’s a capable SUV. But when snow starts falling and roads get slick, understanding how to use your Quadra-Trac 4×4 system properly makes all the difference. It’s not just about having four-wheel drive. It’s about knowing when and how to use it.
TL;DR
The 2020 Grand Cherokee’s Quadra-Trac systems are designed for winter driving, with Snow mode on the Selec-Terrain dial being your best friend on icy roads. Quadra-Trac I works automatically in the background, while Quadra-Trac II and Quadra-Drive II give you more control with a two-speed transfer case and low-range gearing for deep snow. For daily winter driving, keep the system in Auto or select Snow mode — and always check your tires.
Understanding Quadra-Trac Systems on the 2020 Grand Cherokee
Jeep builds the Grand Cherokee with multiple 4×4 systems. Here’s what each one does, plain and simple:
| System | Best For | How It Works |
|---|---|---|
| Quadra-Trac I | Daily commuting, light snow | Full-time 4×4. Works automatically — no driver input needed. |
| Quadra-Trac II | Moderate to heavy snow, unplowed roads | Adds a two-speed transfer case and can send torque to the axle with the most grip. |
| Quadra-Drive II | Deep snow, ice patches, tricky terrain | The most advanced system. Includes a rear electronic limited-slip differential that can send power to a single wheel with traction. |
Which System Does Your Grand Cherokee Have?
Most 2020 Grand Cherokee models come with either Quadra-Trac I or II. The Quadra-Drive II system is usually available on higher trims like the Overland or Summit. You can check your window sticker or look for the Selec-Terrain dial near the gear shifter — if you have one, you’ve got Quadra-Trac II or Quadra-Drive II.
The Secret Weapon: Selec-Terrain Snow Mode
Here’s where the magic happens. The Selec-Terrain system is a dial that lets you choose a driving mode for the conditions. Think of it like presets for different surfaces.
Snow mode does a few smart things:
- The transmission often starts in second gear to reduce wheel spin when you pull away
- Throttle response is softened so you don’t accidentally gun it on ice
- Torque is distributed more carefully between front and rear axles
- Traction control is tuned to be more sensitive
“When in Snow mode, the transmission may use second gear (rather than first gear) during launches, to minimize wheel slippage.” — Jeep Grand Cherokee Operating Manual
When to Use Snow Mode
Any time you see snow, ice, or frost on the road, just twist the dial to Snow. It’s that simple. One owner explained it well: “Select Snow mode. The system softens throttle input and coordinates traction control for smooth takeoffs. Quadra-Trac II adds confident torque transfer when lanes feel polished”.
How to Use Quadra-Trac II in Winter: Step by Step
1. Starting Out on a Snowy Morning
- Turn the dial to Snow before you put the car in gear
- Accelerate gently — the system will handle traction for you
- Leave it in Snow until roads are dry again
If you have Quadra-Trac I, you don’t need to do anything — the system automatically adjusts power delivery as conditions change.
2. Driving on Icy or Slushy Roads
- Keep it in Snow mode for smooth starts and controlled acceleration
- Don’t use 4WD Low unless you’re in deep snow and moving slowly — it’s not meant for highway speeds
- Stay in Auto mode if you’re on roads that are wet but not icy
3. If You Get Stuck (Rocking the Vehicle)
If you end up stuck in deep snow, the owner’s manual says you can “rock” the vehicle free by shifting between DRIVE and REVERSE while applying light pressure on the accelerator.
Important: Turn off the Traction Control system before attempting this. You can usually do this by pressing the ESC Off button.
4. Driving in 4WD Low
4WD Low on Quadra-Trac II is for loose, slippery surfaces only — not for normal driving. Use it for:
- Deep, unplowed snow
- Steep, icy hills
- Pulling a boat up a slippery ramp
The Unsung Hero: Tires
Here’s something many owners realize fast: even the best 4×4 can’t grip on bald tires. One owner who drove through a Wyoming blizzard noted the Grand Cherokee held its ground perfectly — but they had proper tires.
Winter driving requires proper tires. says: “Install winter tires. Winter tires can significantly improve the Grand Cherokee’s snow performance.”
A few quick tire tips:
- Check tread depth — aim for at least 5/32″ for winter
- Tire pressure drops in cold weather — check it monthly
- Consider winter or all-weather tires if you see lots of snow
Optional: Quadra-Lift Air Suspension
If your Grand Cherokee has the optional Quadra-Lift air suspension, you get an extra winter advantage. You can raise the ride height for extra clearance in deep snow, and the system automatically lowers at highway speeds for better stability. Think of it as having a lift kit that works when you need it.
FAQ
What’s the difference between Quadra-Trac I and II?
Quadra-Trac I is full-time 4×4 that works automatically. Quadra-Trac II adds a two-speed transfer case and better low-speed control for deeper snow.
When should I use Snow mode?
Any time roads are icy, snowy, or frosty. It smooths throttle response and reduces wheelspin.
Can I use 4WD Low on the highway?
No. 4WD Low is for slow-speed driving on loose or slippery surfaces, not for normal road speeds.
Do I need winter tires if I have Quadra-Trac?
Yes. 4×4 helps with traction, but tires determine braking and cornering grip. Winter tires make a huge difference.
Should I turn off traction control in snow?
Keep it on for normal driving. Only turn it off if you’re stuck and need to rock the vehicle free.
