What should be noted when activating the 4WD on Haval H3?

When activating the 4WD on Haval H3, it should be noted that this function is best used on icy or snowy roads to enhance the vehicle's driving capability, and should generally be turned off under other road conditions. Below is an introduction to the Haval H3: 1. Model Overview: The Great Wall Haval H3 is a segmented model newly developed to meet different customer needs, inheriting the consistent high quality of the Haval series. The Haval H3 well inherits the characteristics of SUV models, such as spacious interiors and strong off-road capabilities, while further improving comfort, which is comparable to high-end sedans, making it a true all-rounder. 2. Powertrain: The Haval H3 is equipped with a 2.0L-4G63-S4M engine, which is economical, energy-saving, and environmentally friendly. This powertrain features a single overhead camshaft, 16-valve design, and is equipped with the most advanced Delphi radio frequency technology.

As a veteran driver who frequently operates a Haval H3 on construction sites, there are several key points to note when using four-wheel drive. On paved roads, you must use two-wheel drive mode to avoid excessive wear on tires and drive shafts. When switching to high-range four-wheel drive, ensure your speed doesn't exceed 15km/h, preferably performing the shift on straight sections. For situations requiring low-range four-wheel drive (like mud or steep slopes), remember to come to a complete stop and shift to neutral before engaging. Another detail: after each four-wheel drive engagement, drive slowly for 20-30 meters to allow full system synchronization. I've experienced steering difficulties in snow, so I recommend easing off the throttle during turns on slippery surfaces. Always switch back to two-wheel drive after use to avoid prolonged stress on the transfer case. Personally, I make it a habit to activate the four-wheel drive system for about 10 minutes monthly on loose surfaces to prevent component rust and seizure.

As an off-road enthusiast, I have a deep understanding of the 4WD operation of the Haval H3. The most crucial aspect when switching to 4WD is speed control. The shift from 2WD to high-range 4WD should be completed within 5-10 km/h. High-range 4WD is sufficient for sandy or gravel sections, but avoid making sharp turns on hard surfaces with 4WD engaged, as this puts excessive stress on the driveshaft. When climbing steep slopes, remember to switch to low-range 4WD in advance – shifting mid-slope may cause the vehicle to roll back. After each off-road trip, always clean the mud from the undercarriage and specifically check if the 4WD transfer fork is jammed by small stones. While 4WD does improve traction on icy roads, pairing it with winter tires yields better results.

Having repaired cars for 15 years, I've seen too many four-wheel drive systems damaged by improper operation. When switching the four-wheel drive on the Haval H3, you must ensure the transmission is in neutral, otherwise the transfer case gears are prone to grinding. Pay special attention to slipping in rainy or snowy weather when using four-wheel drive, as front wheel spin can easily burn out the clutch plates. One owner drove in four-wheel drive on hard surfaces for an entire week, resulting in the rear axle differential being completely ruined. After using low-range four-wheel drive, promptly switch back to two-wheel drive to prevent the half-shafts from overheating and deforming. The most commonly overlooked aspect is regular maintenance; I recommend changing the transfer case gear oil every 30,000 kilometers to ensure the electromagnetic switching valve functions properly. If the four-wheel drive indicator light starts flashing, stop immediately to check, as it's usually caused by poor contact in the signal wiring.
