This locks the front and rear driveshafts to provide additional power at low speeds or for towing.
Climb over rocks and ridges easily with its Trail Rated® 20:1 crawl ratio and standard Selec-Terrain® Traction Management System – enhanced on the Trailhawk with Rock Mode.
Trust Jeep® 4x4 systems to maintain traction in wet weather or slick road conditions. If the Jeep vehicle features a full‑time 4x4 system, it adapts automatically, while on‑demand or part‑time 4x4 systems are manually engaged.
For deep snow or icy conditions, 4WD LOW provides added control at low speeds. Shifting into a gear lower than necessary can reduce momentum. Over‑revving the engine can cause the tires to spin and lose traction, but if it does happen, turn the steering wheel from side to side rapidly to help the tires establish more grip and deliver more control.
When it comes to off-road driving, easy does it – take things slow and stay in control.
For Jeep® vehicles with 4WD LOW, the low gear and low speed at idle generally provide enough power to ensure most hurdles can be climbed over. For Jeep vehicles with a manual transmission, simply let out the clutch slowly in the lowest gear to overcome obstacles like rocks and logs.
To try out these tips for maximizing vehicle capability, look for a location similar to California’s famously rugged Rubicon® Trail, where the average speed is just 2-8 km/h (1-5 mph).
Advanced preparation is key for high‑performance off‑road driving.
Engage part-time 4x4 systems as soon as the vehicle is off‑road – there’s no need to wait until a sticky situation arises.
Always keep a close eye on the trail ahead to avoid unexpected obstacles and plan the best route around or over them.
The driver’s thumbs should always be up and out of the steering wheel’s way – the steering wheel can rotate suddenly when off‑roading and catch the driver’s thumb with a spoke.
It’s critical to carefully inspect the vehicle before taking it off‑road.
Check under the hood to ensure the battery is securely fastened, all hoses are in good condition and all fluids are at proper levels. Inspect the tires, including the spare, and check that each one is inflated correctly and is in good condition.
Planning to go off the beaten path? Travel with a friend, especially when exploring unfamiliar territory.
Ensure the Jeep® vehicle’s driving line is straight up or down when travelling on a hill. When ascending, apply more power at the bottom and slowly release the gas pedal as the vehicle crests the hill. If it does stall, back straight down carefully before the next attempt. When descending a hill with an automatic transmission, select Low Range and the lowest drive setting. Always use the lowest gear with a manual transmission.
Never disengage the clutch to let the vehicle coast when in Low Range – this could severely damage the clutch disc. Simply let the gears and engine compression do the work and slow the vehicle down, and only apply the brakes to fine‑tune its speed.
NOTE: Never drive up or down a hill at an angle. Driving sideways on a steep slope can result in vehicle instability.
Overcome rocks slowly and steadily in Low Range. Select 4WD LOW in low gear and, at idle speed or using as little throttle as required, climb the rocks at a crawl. Ideally, rock crawling speed is 2-8 km/h (1-5 mph). For additional traction, reduce the vehicle’s tire pressure by 3‑5 PSI, and remember to return it to normal pressure when the off‑road adventure is complete.
NOTE: Do not straddle rocks. Instead, position the tires on top of the rocks and crawl over slowly.
Off‑roading in the sand means mastering momentum and letting the tire treads do the work. To maintain momentum, stay in 4WD HI and take wide turns – tight turns can slow the vehicle, which can cause it to lose traction and get stuck.
For improved traction, reduce the tire pressure by 10‑12 psi and remember to re‑inflate the tires back to normal when finished. If conditions call for 4WD LOW or alternative gear selections, be sure to avoid spinning the tires.
With their array of 4x4 systems, Jeep® vehicles are all about off‑road capability.
Take on some of the most rugged trails and terrain anywhere with the powerful traction of our Trail Rated® 4x4 vehicles. Testing includes traction on steep grades and slick roads (wet, mud, snow).
Minimize the chance of underbody damage when driving over rocks and with Trail Rated® ground clearance.
Every Trail Rated Jeep® is tested and optimized for ground clearance, for ample room between the underside of the vehicle and the terrain below. Plus, approach, departure, and break‑over angles are also maximized, offering choices when driving around an obstacle isn’t possible – because there’s no telling what could get in your Jeep vehicle’s way when off‑roading.
Avoid obstacles with the nimble manoeuvrability of a Trail Rated® Jeep® vehicle.
Narrow gaps, tight trails, and snaking switchbacks are all part of what makes off‑road driving so much fun, and so is the ability to navigate them. That’s why Trail Rated Jeep vehicles feature precision steering and optimized wheelbases. Tested in the toughest and trickiest situations, they deliver dynamic manoeuvrability for all off‑road experiences.
Enhanced articulation ensures wheels remain stable when one or more tires are elevated.
When travelling on tough terrain or even potholed roads, it’s crucial the chassis and suspension are flexible. Thanks to Trail Rated® Jeep® vehicle design, articulation is reinforced with features like solid axles, generous wheel well space, long‑wheel travel, electronic sway bar disconnect, and maximum suspension flexibility. If one tire does come off the ground, these features help keep the other tires firmly planted for full traction.
From flooded creeks to deep puddles, Trail Rated® vehicles are designed for water fording.
Built to keep water out of critical areas while crossing overflowing streams and other bodies of water, Trail Rated vehicles provide extra sealing for electrical connections and body openings. Air intake vents are positioned higher too, so Jeep® vehicles can go where others would never dare.
