RWhile driving, ease up on the accelerator pedal. RAdapt your speed and driving style to the prevailing road conditions. Failure to observe these guidelines could cause the vehicle to skid. The ESP® cannot prevent accidents resulting from excessive speed. Off-road 4ETS (Electronic Traction System) A 4ETS system specifically suited to off-road terrain is activated automatically if the offroad drive program is activated (Y page 204) or the LOW RANGE off-road gear (Y page 157) is selected. ! Only operate the vehicle for a maximum of ten seconds on a brake test dynamometer. Switch off the ignition. Application of the brakes by ESP® may otherwise destroy the brake system. !
