When the vehicle has been parked for some time, the brake pedal may sink more than usual when the engine is started. This is normal and the pedal will return to its usual position when it is released. Symbols in the instrument panel WARNING If and come on at the same time and the brake level is below the MIN mark in the reservoir or if a brake system-related message is shown in the information display: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the brake system inspected. 117 03 Your driving environment Hill Descent Control (HDC) Introduction 1 Normally, when the accelerator pedal is released while driving down hills, the vehicle's speed slows as the engine runs at lower rpm (the normal engine braking effect). However, if the downhill gradient becomes steeper and if the vehicle is carrying a load, speed increases despite the engine braking effect. In this situation, the brakes must be applied to reduce the vehicle's speed. HDC is a type of automatic engine brake and makes it possible to increase or decrease the vehicle's speed on downhill gradients using only the accelerator pedal, without applying the brakes. The brake system functions automatically to maintain a low and steady speed. HDC is particularly useful when driving down steep hills with rough surfaces, and where the road may have slippery patches. WARNING HDC does not function in all situations, and is a supplementary braking aid. The driver has full responsibility for driving in a safe manner. 1 HDC is only available on the XC70, on which it is standard equipment. Function
