What is the correct method for driving a CVT automatic transmission car downhill?

First, firmly engage the handbrake. When starting the car, press the brake pedal with your right foot before starting the engine, then shift to D gear or a low gear. Release the brake and place your right foot on the accelerator pedal. Gradually increase the throttle while slowly releasing the handbrake with your right hand. When going downhill, use a low gear, either 1st or 2nd gear. Do not press the accelerator pedal; let the car descend by inertia, but keep your right foot on the brake pedal to control the speed.
The key to driving a CVT car downhill is engine braking to avoid overheating and failure from prolonged brake use. The specific steps are simple: First, don't shift into N (neutral), as it deprives the transmission of lubrication and increases wear. If the slope is steep, use D (drive) mode combined with manual mode to lock in a low gear, such as 1st or 2nd, keeping the engine RPM above 2000. This allows the engine to drag and slow the car. For long descents, it's best to downshift early rather than waiting until the car speeds up. Keep your foot near the brake pedal but avoid heavy braking—intermittent light taps combined with engine braking ensure safety. This is how I drive my own CVT on mountain roads, protecting the transmission and preventing brake fade.
The biggest fear when driving an automatic transmission downhill is brake overheating and loss of control. CVT transmissions require special attention—never coast in neutral! In neutral, the steel belt lacks hydraulic lubrication, which can cause severe wear over time. The correct approach is to use D gear or directly switch to L gear (some cars have low-speed gears). At this point, the engine RPM will rise, but don’t panic—this is the engine helping you brake. Shift to a lower gear 2-3 kilometers before the descent and maintain a speed below 40 km/h for safety. If you feel the brakes becoming soft during the drive, immediately find a safe area to stop and let them cool down. Having driven many steep downhill sections, I’ve found that maintaining steady throttle control offers better stability than repeatedly tapping the brakes.
There are actually techniques for driving a CVT downhill. First, never coast in neutral (N) gear, as this stops the transmission oil pump and damages the steel belt structure. The correct method is to use Drive (D) gear with engine braking: for longer slopes, switch to manual mode and lock in a lower gear, ensuring the tachometer shows around 2,500 RPM. Lightly press the brake pedal to keep speed below 50 km/h and maintain a safe distance from the vehicle ahead. For minor slopes, using D gear directly is fine, but always shift to a lower gear in advance on winding mountain roads. While automatic transmissions are meant for convenience, it's crucial to monitor transmission load during downhill driving.
