label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or the tire inflation pressure label, you should determine the proper tire infla- tion pressure for those tires). As an added safety feature, your vehicle has been equipped with a tire pressure monitor- ing system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accord- ingly, when the low tire pressure telltale illu- minates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significant- ly under-inflated tire causes the tire to over- heat and can lead to tire failure.


Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehi- cle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driv- er’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.


Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is com- bined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the mal- function indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.


Practical hints What to do if …


TPMS malfunctions may occur for a variety of reasons, including the installation of in- compatible 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.

Problem 1 The red SRS indicator lamp


comes on while driving.


Possible cause/consequence There is a malfunction in the restraint sys- tems. The air bags or emergency tensioning devices (ETDs) could deploy unexpectedly or fail to activate in an accident.


Suggested solution 왘 Drive with added caution to the near-


est authorized Mercedes-Benz Cen- ter.


Warning!


In the event a malfunction of the SRS is indi- cated as outlined above, the SRS may not be operational. For your safety, we strongly recommend that you visit an authorized Mercedes-Benz Center immediately to have the system checked; otherwise the SRS may not be activated when needed in an acci- dent, which could result in serious or fatal injury, or it might deploy unexpectedly and unnecessarily which could also result in an accident and/or injury to you or to others.

Problem


75
The indicator lamp does not illuminate and/or does not remain illuminated with the weight of a typical 12-month-old child in a standard child restraint or less on the front passenger seat.


Suggested solution


Possible cause/conse- quence The system is malfunctioning. 왘 Make sure that there is nothing between seat cush- ion and child seat and check installation of the child seat.


왘 Make sure that no objects applying supplemental


weight onto the seat are present.


왘 Make sure that no objects which apply forces to the seat are present (e.g. objects such as books, brief- cases etc. lodged behind or around the seat, head restraints pushing against roof etc.). The system may recognize such forces as supplemental weight. 왘 If the light remains out, have the system checked as soon as possible by an authorized Mercedes-Benz Center. Do not transport a child on the front passen- ger seat until the system has been repaired.


왘 Read and observe messages in the multifunction display and follow corrective steps (컄 page 390).

Vehicle status messages in the multi- function display


Warning and malfunction messages ap- pear in the multifunction display located in the instrument cluster. Certain warning and malfunction messag- es are accompanied by an audible signal. Address these messages accordingly and follow the additional instructions given in this Operator’s Manual. Selecting the vehicle status message memory menu in the control system (컄 page 164) displays both cleared and uncleared messages. High-priority messages appear in the multifunction display in red color.


Certain messages of high priority cannot be cleared from the multifunction display using the reset button (컄 page 151) or button j, k, ÿ or è on the multifunction steering wheel. Other messages of high priority and mes- sages of less immediate priority can be cleared from the multifunction display using the reset button (컄 page 151) or button j, k, ÿ or è on the multifunction steering wheel. They are then stored in the vehicle status message memory (컄 page 164). Remember that clearing a message will only make the mes- sage disappear. Clearing a message will not correct the condition that caused the message to appear.

Warning!


All categories of messages contain impor- tant information which should be taken note of and, where a malfunction is indicated, ad- dressed as soon as possible at an autho- rized Mercedes-Benz Center.


Failure to repair condition noted may cause damage not covered by the Mercedes-Benz Limited Warranty, or result in property dam- age or personal injury.

Driving with the message Brake fluid Visit workshop displayed can result in an accident. Have your brake system checked immediately.


If there is a malfunction in the electrohy- draulic brake system, we recommend that the vehicle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment.


A tow bar must be used if circumstances do not permit the use of the recommended towing methods and the vehicle requires towing with all four wheels on the ground.


Towing the vehicle with all four wheels on the ground is only permissible for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). For more infor- mation, refer to “Towing the vehicle” (컄 page 458). If the electrohydraulic brake system enters its emergency operation mode, the driver must apply significantly greater brake pedal pressure and depress the pedal much fur- ther than normal to obtain braking effect. If necessary, apply full pressure to the brake pedal. Brakes may only be applied to the front wheels. Stopping distance is in- creased!

Possible solution 왘 Risk of accident! Stop the vehicle in a safe location as soon as it is safe to do so and notify an authorized Mercedes-Benz Center. Do not add brake fluid! This will not solve the problem.


Do not add brake fluid before checking the brake system. Overfilling the brake fluid res- ervoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. You can be seriously burned.
