The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously lit. This sequence will continue upon subsequent vehicle startups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. Airbags 1 2 3 Front airbags Side airbags in the seat backrests Knee airbag Protective action Navigation Reference Mobility Communications Entertainment Servotronic* The concept The Servotronic varies the steering force required to turn the wheels depending on the speed at which you are driving. When you are driving at low speeds, power steering provides more support, i.e. little effort is needed to turn the wheels. Power steering support lessens as your speed increases. The system works automatically. Observe the adjustment instructions on page 41 to ensure the best possible personal protection.< The front airbags help protect the driver and passenger by responding to frontal impacts in which safety belts alone cannot provide adequate restraint. When needed, the side airbags help provide protection in the event of a side impact. The relevant side airbag supports the head and the side upper body area. The airbags have been designed to not be triggered in every collision situation, e.g. not in minor accidents or rear-end collisions. Do not apply adhesive materials to the cover panels of the airbags, cover them or modify them in any other way. Keep the dashboard and window on the passenger side clear, i.e. do not cover with adhesive labels or coverings, and do not attach holders such as for navigation instruments and mobile phones. Do not attach seat covers, cushions or other objects to the front seats that are not specifically approved for seats with integral side airbags. Do not hang items of clothing such as coats or jackets over the backrests.
