not be long enough for the integrated signal transmitter to pick up the signal during programming. Similar to this Canadian law, some U.S. gate operators are designed to "time-out" in the same manner. If you live in Canada or have difficulties programming the garage door opener (regardless of where you live) when using the programming steps (see above), proceed as follows: X Press transmitter button (;, = or ?) and hold it down during the following steps until the setup has been completed successfully.

X At the same time, press transmitter button B of the garage door remote control for two seconds, then release it for two seconds, then press it again for two seconds.

X Repeat this sequence on transmitter button B of the garage door remote control until the frequency signal has been learned.

X If the setup procedure is successful,

indicator lamp : flashes once slowly and goes out after a few seconds.

X Continue with the other programming

steps (see above).

Problems when programming If you have problems when programming the integrated remote control, please note the following: Rcheck the transmitter frequency of garage door remote control A (which can usually be found on the rear of the remote control). The integrated remote control is compatible with equipment that operates in the frequency range 280 to 390 MHz.

Rreplace the batteries in garage door remote control A. This increases the likelihood of garage door remote control A sending a strong and precise signal to the integrated remote control on the rear-view mirror.

RWhen aiming the garage door remote

control at the transmitter buttons on the rear-view mirror, hold garage door remote control A at differing distances and angles from the transmitter button that you are programming. Try different angles from a distance of 2 to 12 inches (5 to 30 cm) or the same angle from differing distances.

RIf there is another garage door remote

control for the same device, perform the programming steps again using the remote control. Before performing these steps, make sure that new batteries have been installed in the garage door remote control. RAlign the antenna cable of the garage door

opener unit. This can improve signal reception/transmission.

Opening or closing the garage door Once programmed, the integrated remote control will assume the function of the garage door system's remote control. Please also read the operating instructions for the garage door system. X Turn the SmartKey to position 2 in the

Engine oil Notes on the oil level Depending on the driving style, the vehicle consumes up to 0.9 US qt (0.8 l) of oil over a distance of 600 miles (1000 km). The oil consumption may be higher than this when the vehicle is new or if you frequently drive at high engine speeds. When checking the oil level: Rpark the vehicle on a level surface. Rthe engine should be switched off for at

least five minutes if the engine is at normal operating temperature.

Rthe engine should be switched off for at

least 30 minutes if it is not at normal operating temperature (i.e. if you only start the engine briefly).

Checking the oil level using the oil dipstick

X Pull oil dipstick : out of the dipstick guide

tube.

X Wipe off oil dipstick :. X Slowly insert oil dipstick : into the

Adding engine oil H Environmental note When adding oil, take care not to spill any. If oil enters the soil or waterways, it is harmful to the environment.

! Only use engine oils and oil filters which

have been approved for vehicles with a service system. A list of the engine oils and oil filters that have been tested and approved according to the Mercedes-Benz specifications for service products can be found on the Internet at http:// www.mbusa.com (USA only). Further information on tested and approved engine oils and oil filters can be obtained from any authorized Mercedes-Benz Center. The following causes engine failure or damage to the exhaust system: Rusing engine oils and oil filters that are not specifically approved for the service system

Rreplacing the engine oil and oil filter later than the specified replacement interval required by the service system

Rusing engine oil additives

Example: engine oil cap

Engine oil cap (AMG vehicles) X Turn cap : counter-clockwise and remove

it.

X Add the amount of oil required. Fill carefully to the maximum mark on the oil dipstick. i The difference in quantity between the

MIN mark and the MAX mark on the dipstick is (depending on the engine) approximately 1.6 to 2.1 US qt. (1.5 to 2 l). ! Do not add too much oil. If the oil level is above the MAX mark on the dipstick, too much oil has been added. This can lead to damage to the engine or the catalytic converter. Have excess oil siphoned off.

Further information on engine oil (Y page 308). X Replace cap : on the filler neck and

tighten clockwise. Ensure that the cap locks into place securely.

Checking and adding other service products Checking the coolant level Only check the coolant level when the vehicle is on a level surface and the engine has cooled down. X Turn the SmartKey to position

On vehicles with KEYLESS-GO, press the Start/Stop button twice (Y page 132).

X Check the coolant temperature display in

the instrument cluster. The coolant temperature must be below 158 ‡ (70 †). G Warning In order to avoid any potentially serious burns: Ruse extreme caution when opening the hood if there are any signs of steam or coolant leaking from the cooling system, or if the coolant temperature display indicates that the coolant is overheated.

Rdo not remove the pressure cap on the

coolant reservoir if the coolant temperature is above 158 ‡ (70 †). Allow the engine to cool down before removing the cap. The coolant reservoir contains hot fluid and is under pressure.

Rusing a rag, slowly turn the cap

approximately 1/2 turn to relieve excess pressure. If opened immediately, scalding hot fluid and steam will be blown out under pressure.

Rdo not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts.
