198 Displays and operation Vehicle equipment i This manual describes all the standard and optional equipment of your vehicle which was available at the time of purchase. Country-specific differences are possible. Bear in mind that your vehicle may not feature all functions described here. This also refers to safety-related systems and functions. Important safety guidelines You will find an illustration of the instrument cluster in the "At a glance" section (Y page 28). If you must continue to drive, do so with added caution. Contact an authorized MercedesBenz Center as soon as possible. On-board computer and displays G Warning G Warning Malfunction and warning messages are only indicated for certain systems and are intentionally not very detailed. The malfunction and warning messages are simply a reminder with respect to the operation of certain systems. They do not replace the owner's and/or driver's responsibility to maintain the vehicle's operating safety. Have all required maintenance and safety checks performed on the vehicle. Bring the vehicle to an authorized Mercedes-Benz Center to address the malfunction and warning messages. A driver's attention to the road and traffic conditions must always be his/her primary focus when driving. For your safety and the safety of others, selecting features through the multifunction steering wheel should only be done by the driver when traffic and road conditions permit it to be done safely. Bear in mind that at a speed of just 30 mph (approximately 50 km/h ), your vehicle is covering a distance of 44 feet (approximately 14 m) every second. Displays and operation Tachometer The red band in the tachometer indicates the engine's overrevving range. ! Do not drive in the overrevving range, as this could damage the engine. The fuel supply is interrupted to protect the engine when the red band is reached. Outside temperature display The outside temperature display is in the multifunction display. G Warning! No messages will be displayed if either the instrument cluster or the multifunction display is inoperative. As a result, you will not be able to see information about your driving conditions, such as Rspeed Routside temperature Rwarning/indicator lamps Rmalfunction/warning messages Rfailure of any systems Driving characteristics may be impaired. G Warning! The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges. Changes in the outside temperature are displayed after a short delay.
