128 Driving 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. Notes on breaking-in a new vehicle The first 1000 miles (1500 km) The more you look after the engine when it is new, the happier you will be with its performance in the future. RDrive Driving Important safety notes G Warning Make sure absolutely no objects are obstructing the pedals' range of movement. Keep the driver's footwell clear of all obstacles. If there are any floormats or carpets in the footwell, make sure the pedals still have sufficient clearance. During sudden driving or braking maneuvers the objects could get caught between the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury. Driving and parking G Warning at varying vehicle speeds and engine speeds for the first 1000 miles (1500 km) for this reason. RAvoid overstraining the vehicle during this period, e.g. driving at full throttle. RChange gear in good time, at the latest when the tachometer needle is 2/3 of the way to the red area in the tachometer display. RDo not manually shift to a lower gear to brake the vehicle. RIf possible, do not depress the accelerator pedal past the point of resistance (kickdown). ROnly select shift ranges 3, 2 or 1 when driving slowly, e.g. in mountainous terrain. RIdeally, drive program E should be selected for driving the first 1000 miles (1500 km). After 1000 miles (1500 km) you may gradually bring the vehicle up to full road and engine speeds. On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control. G Warning It is dangerous to shift AUTOTRONIC out of parking position P or neutral position N if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal. i Also observe these breaking-in notes when the vehicle's engine, front-axle transmission or differential have been replaced. i Always observe the respective limit speeds. ! Warm up the engine quickly. Do not use the engine's full performance until it has reached operating temperature. Only shift the automatic transmission to the desired drive position when the vehicle is stationary. Where possible, avoid spinning the drive wheels when pulling away on slippery roads. You could otherwise damage the drive train.
