This article will help you to know that how to engage 4 wheel drive GMC Sierra, allowing drivers to utilize this feature and maximize their off-road adventures fully.
5 Different 4 Wheel Drive Modes on the GMC Sierra:
When selecting the appropriate 4-wheel drive mode, GMC has equipped the Sierra with five options. These modes can quickly be accessed using a dial or button on the dashboard. With these five driving modes available in the GMC Sierra‘s 4WD system, drivers have ultimate control over their vehicle’s performance in any given situation. Whether navigating through snow-covered roads or tackling rugged terrains off the beaten path, the GMC Sierra’s versatile 4-wheel drive capabilities provide a smooth and confident ride every time.
1. 2WD Mode
2WD mode is a driving setting where power is exclusively directed to the rear two wheels of a vehicle. This configuration is mainly intended for regular driving on paved roads and highways, as it does not necessitate additional power or traction control. By distributing power solely to the rear wheels, vehicles can maintain stability and manoeuvrability during normal driving conditions.
2. 4WD High
The 4WD High range mode is desig to improve traction and control in challenging off-road terrains. Distributing power to all four wheels allows for better grip on surfaces like snow, mud, or sand. This mode is beneficial when driving on unpaved roads or trails, as it provides extra stability and prevents the vehicle from getting stuck.
3. 4WD Low
4WD Low drive mode tackles the most challenging off-road conditions, such as steep hills and rocky terrains. When engaged, power is distributed evenly to all four wheels at a reduced speed but with significantly higher torque than the 4H mode. This setup allows for enhanced traction and better vehicle movement control in treacherous terrains.
4. Auto 4WD
The GMC Sierra offers a unique feature called the automatic 4WD system, known as Auto 4WD. This advanced technology automatically senses wheel slip and engages the 4WD mode accordingly. By default, when the truck operates in normal driving conditions, it runs in the efficient 2WD mode to maximize fuel efficiency and optimize performance. When the system detects any signs of wheel slippage due to slippery or uneven terrain, it seamlessly switches on the 4WD system to provide enhanced traction and control.
5. Neutral Mode
Neutral mode, often called N mode, is a crucial feature in trucks that allows for the disconnection of the transmission from the drivetrain. This disengagement is highly beneficial for towing or pulling operations, as it effectively prevents potential damage to the transmission system. By shifting into neutral, the truck’s engine power is disconnected from the wheels, and GMC reduced engine power reset. Reducing strain on vital components and enabling safe transportation without putting unnecessary stress on the drivetrain.
