If you own a 2017 Jeep Grand Cherokee, you have a powerful SUV built for both city driving and off-road adventures. One of its key features is the 4-wheel drive (4WD) system. Knowing how and when to use 4WD can keep you safe, extend your vehicle’s life, and help you get the most from your Jeep. Many owners are unsure how to put their Grand Cherokee in 4WD, especially with different trim levels and 4WD systems. This guide will walk you through the process, explain settings, and share tips you won’t find in the manual.
Understanding Your 2017 Jeep Grand Cherokee 4wd System
The 2017 Grand Cherokee comes with a few different 4WD systems. Most models feature either Quadra-Trac I, Quadra-Trac II, or Quadra-Drive II. Each has different controls and capabilities. The Quadra-Trac I is a full-time 4WD system with no low range, while the Quadra-Trac II and Quadra-Drive II include low-range gearing for more difficult terrain.
Common 4wd Modes
- Auto (Full-time 4WD): The system decides when to engage 4WD for you.
- 4WD Low: For tough terrain, deep snow, mud, or sand.
- Snow, Sand, Mud, Rock: Terrain-specific modes for best traction.
You can usually find your system type in your owner’s manual, or by checking the center console near your gear selector.
How To Engage 4wd In The 2017 Jeep Grand Cherokee
Switching your Jeep into 4WD is simple, but the exact steps depend on your system and driving conditions.
For Quadra-trac I
This system is always in 4WD Auto. There is no need to push a button or shift a lever—the system manages power distribution automatically. You drive as usual, and the vehicle decides when 4WD is needed.
For Quadra-trac Ii And Quadra-drive Ii
These systems offer more control. Here’s how to use them:
- Stop the vehicle and keep your foot on the brake.
- Shift the transmission into Neutral (N).
- Locate the 4WD control switch next to the gear shifter.
- Turn the dial to select your desired mode:
- For normal driving, use Auto.
- For off-road or slippery conditions, choose 4WD Low.
- Wait for the indicator light to confirm the mode is engaged.
- Shift the transmission back to Drive (D) or Reverse (R) as needed.
Important: Only shift into 4WD Low when stopped and in Neutral. Never switch to 4WD Low while moving, as this could damage your drivetrain.
Switching Between Modes
- To return to Auto, stop and shift to Neutral first, then turn the dial.
- Terrain modes (Snow, Sand, Mud, Rock) can usually be selected while driving at low speeds.
When Should You Use 4wd?
Not every situation calls for 4WD. It’s most useful in these scenarios:
- Snow or ice: Extra grip helps prevent slipping.
- Mud, sand, or deep gravel: Avoid getting stuck.
- Steep hills or rocky trails: Maintains traction on uneven ground.
Driving in 4WD on dry pavement is not recommended, except with Quadra-Trac I. It can cause extra wear and tear on your tires and drivetrain.
Table: 4wd Systems Comparison
This table helps you see the differences among the three main 4WD systems for the 2017 Grand Cherokee.
| System | Low Range | Terrain Modes | Best Use |
|---|---|---|---|
| Quadra-Trac I | No | Auto | Everyday, light off-road |
| Quadra-Trac II | Yes | Auto, Snow, Sand, Mud, Rock | Moderate off-road, snow |
| Quadra-Drive II | Yes | Auto, Snow, Sand, Mud, Rock | Heavy-duty off-road |
Tips For First-time 4wd Users
- Practice in a safe area. Try switching modes in your driveway or an empty parking lot before heading off-road.
- Listen for sounds. You may hear a small clunk when engaging 4WD Low; this is normal.
- Don’t force the switch. If the lever or dial won’t move, make sure you’re fully stopped and in Neutral.
- Check the dashboard lights. The indicator should confirm which mode is active. If it blinks or won’t engage, something may be wrong.
- Read the owner’s manual. Every Jeep may have slight differences.
Table: Terrain Modes And What They Do
Understanding what each terrain mode does can help you pick the right one for your trip.
| Mode | What It Does | Best For |
|---|---|---|
| Auto | Balances power automatically | Most conditions |
| Snow | Limits wheel spin, starts in 2nd gear | Slippery roads, ice |
| Sand | More power to wheels, less traction control | Soft sand, dunes |
| Mud | Allows wheels to spin for traction | Deep mud, wet fields |
| Rock | Low speed, maximizes traction | Rocky trails, climbing |
Common Mistakes To Avoid
- Engaging 4WD Low while moving: Always stop and shift to Neutral first.
- Driving fast in 4WD Low: This mode is only for speeds under 25 mph.
- Using 4WD on dry pavement: This increases wear and may cause drivetrain damage.
- Ignoring warning lights: If the 4WD light flashes or stays on, check your manual or see a mechanic.
Table: 4wd Indicator Lights
Here’s how to read some common dashboard lights related to 4WD.
| Light | Meaning | Action Needed |
|---|---|---|
| Solid 4WD | 4WD engaged | Drive as normal |
| Blinking 4WD | Shifting in progress or error | Wait, or check manual if it continues |
| Service 4WD | System fault detected | Visit a mechanic |
Non-obvious Insights
Many owners do not realize that tire size and wear can impact 4WD performance. Mismatched tires may confuse the sensors and cause strange behavior. Also, if your battery is weak, the electronic system may not shift into 4WD Low properly. These details are often missed but can save you time and money.
