Before the start of the winter season (or once a year in the hot southern regions), you should have the anticorrosion/antifreeze concentration checked. The coolant is also regularly checked each time you bring your vehicle to your authorized Mercedes-Benz Center for service. Anticorrosion/antifreeze quantity


Approximately freeze protection – 35°F (– 37°C)


– 49°F (– 45°C)


4.8 US qt (4.5 l)


5.3 US qt (5.0 l)


will increase due to the lower heat transfer capability of the solution. Therefore, do not use more than this amount of anticorrosion/antifreeze. If the coolant level is low, water and MB anticorrosion/ antifreeze should be used to bring it up to the proper level (have cooling system checked for signs of leakage). The water in the cooling system must meet minimum requirements, which are usually satisfied by normal drinking water. If your are not sure about the water quality, consult your authorized Mercedes-Benz Center.


Anticorrosion/antifreeze Your vehicle contains a number of aluminium parts. The use of aluminium components in motor vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifically formulated to protect the aluminium parts. (Failure to use such anticorrosion/ antifreeze coolant will result in a significantly shortened service life.) Therefore the following product is strongly recommended for use in your vehicle: Mercedes-Benz anticorrosion/antifreeze agent.


may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction The traction grades, from highest to lowest are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.


Warning! The traction grade assigned to this tire is based on straightahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.


Consumer information This has been prepared as required of all manufactures of passenger cars under Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the “National Traffic and Motor Vehicle Safety Act of 1966”. Uniform tire quality grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example:


Tread wear 200


Traction AA


Temperature A


All passenger car tires must conform to federal safety requirements in addition to these grades. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and

Temperature The temperature grades are A (the highest), B, and C, representing the tire‘s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.


Warning! The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build up and possible tire failure.

Vehicle keys Included with your vehicle are 2 electronic main keys with integrated radio frequency and infrared remote controls plus removable mechanical key. The locking tabs for the mechanical key portion of the two electronic main keys are a different color to help distinguish it.


Warning! When leaving the vehicle always remove the electronic key from the starter switch, and lock your vehicle. Do not leave children unattended in the vehicle, or with access to an unlocked vehicle. Unsupervised use of vehicle equipment may cause serious personal injury.


Electronic main key


P80.35-2031-26


The electronic main key has an integrated radio frequency and infrared remote control, plus removable mechanical key. The remote control (1) operates all locks on the vehicle. The mechanical key (2) works only in the driver’s door, trunk, and storage compartment locks.


When using the mechanical key (2) for lock operations, it can be removed by sliding it out of the remote control. To do so, move locking tab (3) to the right and slide the mechanical key (2) in direction of arrow (4). The remote control transmitter is located in the electronic main key. The infrared receivers are located in the front door handles.


Note: Remove the mechanical key from the electronic main key when using valet parking service. To prevent access to trunk or storage compartments lock them separately and retain the mechanical key. See page 35 for separate locking of trunk and page 194 for locking of glove box.


Obtaining replacement keys Your vehicle is equipped with a theft deterrent locking system requiring a special key manufacturing process. For security reasons, replacement keys can only be obtained from your authorized Mercedes-Benz Center.

Important! Removing the electronic key from the starter switch activates the start lock-out. The engine cannot be started. Inserting the electronic key in the starter switch deactivates the start lock-out.


Note: In case the engine cannot be started (vehicle’s battery is in order), the system is not operational. Contact an authorized Mercedes-Benz Center or call 1-800-FOR- MERCedes (in the USA), or 1-800-387-0100 (in Canada).


General notes on the central locking system • If the electronic key is inserted in the starter switch,


the vehicle cannot be locked or unlocked with the remote control.


If the vehicle cannot be locked or unlocked: • Aim transmitter eye at a receiver of either front door


handle. Check the batteries of the electronic main key, see page 332, or synchronize the electronic main key, see page 334.


• Use the mechanical key to unlock the vehicle. To


start engine, insert the electronic key in the starter switch. There could be a slight delay until the electronic key can be turned in the starter switch.


Important! When unlocking the driver’s door with the mechanical key, the exterior lamps will flash and the alarm will sound. To cancel the alarm, insert the electronic key in the starter switch or press button Œ or ‹ on the electronic main key.


Central locking system


Radio frequency and infrared remote control The electronic main key has an integrated radio frequency and infrared remote control. Due to the extended operational range of the remote control, it could be possible to unintentionally lock or unlock the vehicle by pressing the transmit button. If one of the transmit buttons is pressed, the battery check lamp lights up briefly – indicating that the batteries are in order. See page 332 for checking batteries. The vehicle doors, trunk and fuel filler flap can be centrally locked and unlocked via remote control. Opening and closing the windows and sliding/pop-up roof can only be done with the infrared portion of the remote control. Aim transmitter eye at a receiver (6 or 7), press and hold transmit button Œ or ‹, see page 29. With vehicle centrally locked, the trunk can also be opened by using the remote control. If the electronic key is inserted in starter switch, the vehicle cannot be locked or unlocked, and the trunk lid cannot be opened with the remote control.
