Things to Remember When Driving

Vehicle features and options

This chapter describes all standard, country-specific and optional features offered with the series. It also describes features and functions that are not necessarily available in your vehicle, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems. When using these functions and systems, the applicable laws and regulations must be observed.


General information
Moving parts need to begin working together smoothly.
The following instructions will help you to achieve a long vehicle life and good efficiency.
During break-in, do not use the Launch Control.

Safety information
Due to new parts and components, safety and driver assistance systems can react with a de‐lay. There is a risk of accident. After installing new parts or with a new vehicle, drive conservatively and intervene early if necessary. Observe the break-in procedures of the respective parts and components.

Engine, transmission, and axle drive
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road speed:

  • For gasoline engine 4,500 rpm and 100 mph/160 km/h.
  • Avoid full throttle or kickdown under all circum‐stances.
    From 1,200 miles/2,000 km
    The engine and vehicle speed can gradually be increased.
  • Tires
    Tire traction is not optimal due to manufacturing circumstances when tires are brand-new; they achieve their full traction potential after a break-in time.
    Drive conservatively for the first
    200 miles/300 km.
  • Brake system

  • Brake discs and brake pads only reach their full effectiveness after approx. 300 miles/500 km. Drive moderately during this break-in period.
  • Following part replacement
    Observe the break-in procedures again, if the components mentioned above are replaced.

Closing the trunk lid Safety information

Driving with the trunk lid open
If driving with the tailgate open cannot be avoided:

  1. Close all windows and the glass sunroof.
  2. Greatly increase the blower output.
  3. Drive moderately.

Hot exhaust gas system

High temperatures can occur underneath the body, for instance, caused by the exhaust gas system, while driving. Contact with the exhaust gas system can cause burns. There is a risk of injury. Do not touch the hot exhaust gas system, including the exhaust pipe.

If combustible materials, such as leaves or grass, come in contact with hot parts of the exhaust gas system, these materials can ignite. There is a risk of fire and an injury hazard. Do not remove the heat shields installed and never apply undercoating to them. Make sure that no combustible materials can come in contact with hot vehicle parts while driving, at idle or during parking.

Mobile communication devices in the vehicle

Vehicle electronics and mobile phones can influence one another. There is radiation due to the transmission operations of mobile phones. There is a risk of injury or risk of damage to property. If possible, in the car’s interior use only mobile phones with direct connections to an external antenna in order to exclude mutual interference and deflect the radiation from the car’s interior.


On wet or slushy roads, a wedge of water can form between the tires and the road surface.
This phenomenon is referred to as aquaplaning. It is characterized by a partial or complete loss of contact between the tires and the road surface, ultimately undermining your ability to steer and brake the vehicle.

Driving through water

General information
When driving through water, follow the following:

  1. Deactivate Auto Start/Stop function.
  2. Drive through calm water only.
  3. Drive through water only if it is not deeper than the maximum of 9.8 inches/25 cm.
  4. Drive through water no faster than walking speed, up to 3 mph/5 km/h.

Safety information
When driving too quickly through too deep water, water can enter into the engine compartment, the electrical system or the transmission. There is a risk of damage to property, among other potential damage. When driving through water, do not exceed the maximum indicated water level and the maximum speed for driving through water.
