Operation Driving instructions ! Set the parking brake whenever parking or leaving the vehicle. In addition, move gear selector lever to position P. In addition, when parking on hills, always set the parking brake and turn front wheel towards the road curb. Tires Tread wear indicators (TWI) are required by law. These indicators are located in six places on the tread circumference and become visible at a tread depth of approximately 1⁄16 in (1.6 mm), at which point the tire is considered worn and should be replaced. The tread wear indicator appears as a solid band across the tread. Specified tire pressures must be maintained. This applies particularly if the tires are subject to high loads (e.g. high speeds, heavy loads, high ambient temperatures). Warning! G Warning! G Warning! G If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the road. Inspect the tires and the vehicle underbody for possible damage. If the vehicle or tires appear unsafe, have it towed to the nearest Mercedes-Benz Light Truck Center or tire dealer for repairs. Although the applicable federal motor vehicle safety laws consider a tire to be worn when the tread wear indicators (TWI) become visible at approximately 1⁄16 in (1.6 mm), we recommend that you do not allow your tires to wear down to that level. As tread depth approaches 1⁄8 in (3.0 mm), the adhesion properties on a wet road are sharply reduced. Depending upon the weather and/or road surface (conditions), the tire traction varies widely. Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat build-up and possibly a fire. Hydroplaning Depending on the depth of the water layer on the road, hydroplaning may occur even at low speeds and with new tires. Reduce vehicle speed, avoid track grooves in the road and apply brakes cautiously in the rain. 210
