Turn off the engine. Wait at least 10 seconds before restarting. Restart the engine. Shift the automatic transmission into drive position D (for second gear) or reverse gear R. Have the automatic transmission checked at an authorized Mercedes-Benz Center as soon as possible. ! Only conduct operational or performance tests on a two-axle dynamometer. If such tests are necessary, contact an authorized Mercedes-Benz Center. You could otherwise seriously damage the brake system or the transfer case which is not covered by the Mercedes-Benz Limited Warranty. ! Because the ESP® operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the parking brake is being tested on a brake test dynamometer. Such testing should be no longer than 10 seconds. Active braking action through the ESP® may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty. X 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 speed or outside temperature, warning/indicator lamps, malfunction/ warning messages or the failure of any systems. Driving characteristics may be impaired. If you must continue to drive, please do so with added caution. Contact an authorized Mercedes-Benz Center as soon as possible. Z 143
