Important safety notes
WARNING
Grains of sand, particles of dirt and other abrasive materials can enter the brake system. This can lead to excessive wear and unpredictable braking efficiency.
After the brakes have been exposed to dirty conditions, have them checked and cleaned at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. Otherwise, there is a risk that braking power may be insufficient in the event of an emergency, or that the braking effect may be unpredictable.
WARNING
Do not reduce the tire inflation pressure before driving through sand. However, if you do so, remember to correct the tire inflation pressure before continuing your trip. Driving with reduced tire inflation pressure increases the risk of losing control of the vehicle and rolling over.
