Engaging four-wheel drive in your Jeep Grand Cherokee requires a simple shift of the transfer case lever while the vehicle is moving slowly. If you’re wondering how to put jeep grand cherokee in 4 wheel drive, the process depends on your model year and transfer case type. This guide covers all common systems, from the classic Command-Trac to the modern Selec-Trac and Quadra-Trac setups.
Most Grand Cherokees use a lever or rotary dial to select 4WD modes. The key is to do it at the right speed and on the right surface. Let’s walk through the steps for each system.
How To Put Jeep Grand Cherokee In 4 Wheel Drive
Before you start, make sure you are on a loose or slippery surface like dirt, gravel, or snow. Engaging 4WD on dry pavement can damage the drivetrain. Also, ensure the transmission is in neutral or park for some systems.
Step-By-Step For Command-Trac Or Selec-Trac Lever Systems
These systems use a floor-mounted lever with positions like 2HI, 4HI, N, and 4LO. Follow these steps:
- Slow down to under 55 mph (88 km/h) for 4HI. For 4LO, stop the vehicle completely.
- Shift the transmission into neutral.
- Pull the transfer case lever straight back from 2HI to 4HI. You should feel a firm click.
- For 4LO, push the lever forward and to the left, then down into the 4LO slot.
- Shift the transmission back into drive and proceed slowly.
If the lever feels stiff, try rolling forward a few feet while in neutral. This aligns the gears. Never force the lever.
Using The Rotary Dial On Newer Models
Many 2014 and newer Grand Cherokees have a rotary dial on the center console. The positions are similar: 2HI, 4HI, N, and 4LO. Here is how to use it:
- For 4HI: Turn the dial from 2HI to 4HI while driving under 55 mph. No need to stop.
- For 4LO: Stop the vehicle, shift to neutral, then turn the dial to 4LO. Wait for the indicator light to stop flashing.
- To return to 2HI, simply turn the dial back while driving under 55 mph.
Some models require you to press a button on the dial to engage 4LO. Check your owner’s manual for specifics.
Quadra-Trac I And II Systems
These are full-time 4WD systems found on higher trims. They operate automatically but offer a 4LO mode for off-road use. To engage 4LO:
- Stop the vehicle completely.
- Shift the transmission into neutral.
- Press the 4LO button on the center console or turn the dial to 4LO.
- Wait for the indicator light to stay solid. This may take a few seconds.
- Shift back into drive and proceed.
Quadra-Trac II also has a neutral position for towing. Use the same process but select N instead.
Common Mistakes And How To Avoid Them
Many drivers make errors when engaging 4WD. Here are the most common:
- Engaging 4WD on dry pavement: This causes binding and tire wear. Only use 4WD on loose or slippery surfaces.
- Shifting into 4LO while moving: Always stop first. Shifting into 4LO at speed can damage the transfer case.
- Ignoring flashing lights: If the 4WD indicator blinks, the system did not engage. Stop, shift to neutral, and try again.
- Forcing the lever: If the lever is hard to move, roll the vehicle slightly. Never use excessive force.
When To Use Each 4WD Mode
Understanding the modes helps you use them correctly. Here is a quick guide:
- 2HI: Use on dry pavement for normal driving. This saves fuel and reduces wear.
- 4HI: Use on loose surfaces like gravel, mud, or snow. Provides extra traction at higher speeds.
- 4LO: Use for slow, technical off-road driving like rock crawling or steep inclines. Provides maximum torque.
- N: Use only for flat towing behind an RV. Never drive in this mode.
Troubleshooting If 4WD Won’t Engage
Sometimes the system may not engage. Here are common causes and fixes:
- Check the transmission: Ensure it is in neutral. Some systems require neutral for 4LO.
- Check the speed: You must be under 55 mph for 4HI and stopped for 4LO.
- Check the indicator: If the light blinks, the system is trying but failed. Try shifting to neutral and back.
- Check for mechanical issues: A faulty transfer case motor or low fluid can prevent engagement. Consult a mechanic.
Maintenance Tips For Your 4WD System
Regular maintenance keeps your 4WD working. Follow these tips:
- Engage 4WD monthly: Even if you don’t need it, shift into 4HI and drive a short distance to lubricate components.
- Check fluid levels: The transfer case and differentials need proper fluid. Change them per the owner’s manual.
- Listen for noises: Grinding or clunking sounds indicate a problem. Get it checked promptly.
- Inspect seals: Leaks can cause low fluid and failure. Look for drips under the vehicle.
Safety Precautions When Using 4WD
Four-wheel drive gives you more traction, but it does not make you invincible. Remember these safety points:
- Drive slower: 4WD helps you go, but it does not help you stop. Reduce speed on slippery roads.
- Avoid sudden turns: 4WD can cause understeer on loose surfaces. Turn smoothly.
- Know your limits: 4WD does not prevent sliding on ice. Use caution in winter conditions.
- Disengage on pavement: Return to 2HI when you reach dry roads to prevent drivetrain damage.
Special Considerations For Older Models
If you have a 1990s or early 2000s Grand Cherokee, the process may differ slightly. Here are some tips:
- Some older models have a vacuum-actuated front axle. This may require the engine to be running.
- Manual transfer cases often need you to shift while rolling slowly. Follow the same steps but at a crawl.
- Check the owner’s manual for your specific year. Procedures vary between generations.
Off-Road Driving Tips With 4WD
Using 4WD off-road requires some technique. Here are basic tips:
- Air down tires: Lowering tire pressure improves traction on sand or rocks. Reinflate before driving on pavement.
- Use 4LO for crawling: This gives you better control at low speeds. Shift before you need it.
- Avoid spinning wheels: If you lose traction, ease off the gas. Spinning digs you in deeper.
- Know your clearance: The Grand Cherokee has good ground clearance, but watch for high obstacles.
Common Questions About Grand Cherokee 4WD
Here are answers to frequent queries:
Can I shift into 4HI while driving?
Yes, on most models you can shift into 4HI at speeds up to 55 mph. Just pull the lever or turn the dial. No need to stop.
Why does my 4WD light flash?
A flashing light means the system is trying to engage but has not. Stop, shift to neutral, and try again. If it persists, check for mechanical issues.
Do I need to use 4WD in rain?
No, 4WD is not necessary in rain on paved roads. It can actually cause handling issues. Stick to 2HI unless conditions are slippery.
How do I know if my 4WD is working?
Engage 4WD on a loose surface and accelerate gently. You should feel the front wheels pulling. You can also check the indicator light on the dashboard.
Final Thoughts On Engaging 4WD
Learning how to put jeep grand cherokee in 4 wheel drive is straightforward once you know your system. Whether you have a lever or dial, the steps are simple. Always follow the speed and surface guidelines to avoid damage. Practice in a safe area to get comfortable with the process. With proper use, your Grand Cherokee’s 4WD system will serve you well for years.
Remember to consult your owner’s manual for model-specific instructions. If you have persistent issues, visit a qualified mechanic. Now you are ready to tackle off-road trails or snowy roads with confidence.
