Whereas in older rides like an Isuzu Trooper, the same task is tough and requires better and more precise understanding from the driver.
2. Assess the Terrain
Carefully examine the road ahead and understand the challenges before engaging either of the two modes. If there are extreme conditions like deep mud, steep inclines, rocky obstacles, or snow, go for 4L mode. Use 4H if driving on moderate off-road trails or slippery surfaces where a higher speed is manageable.
3. Monitor Your Speed
Always, always drive within the recommended speed ranges for each mode to avoid mechanical strain and severe damage to your ride. 4L should be engaged at very low speed (typically 0–20 mph) to maintain maximum control. Whereas for a faster drive (usually 20–55 mph), 4H is right, but avoid sudden acceleration or braking as it can upset the balance of your vehicle.
4. Smooth Transitions
When switching between the two modes (which we will learn in detail in the following section), make sure your automobile is either moving very slowly or is at a complete stop, as recommended by the manufacturer. Doing this will minimize the risk of drivetrain damage.
5. Tire and Traction Check
Make sure your tires are in good condition and are well suited for off-road conditions. Adequate tread and proper inflation are absolutely necessary for optimal traction and handling.
6. Environmental Awareness
Never ignore the weather conditions. Wet, icy, or extremely muddy surfaces require more caution than the dry roads. So, adjust your driving style accordingly and be ready to switch back to a more appropriate mode if conditions change.
7. Regular Drills and Practice
Practice shifting between 4L and 4H modes in a controlled driving environment before taking on your new terrain challenge. Doing this will build your muscle memory and help you respond quickly and confidently in unexpected situations.
8. Emergency Preparedness
Whenever going on a challenging off-road adventure, always carry recovery gear, a first aid kit, and communication devices. Knowing how to handle minor mishaps can come in extremely handy when exploring the road less taken.
