SmartKey with KEYLESS-GO*

Specially equipped vehicles come with two SmartKeys with KEYLESS-GO, each with remote control and a removable mechani- cal key. The locking tabs for the mechani- cal key portion of the two SmartKeys are a different color to help distinguish each SmartKey unit. The KEYLESS-GO function is integrated into the SmartKey. On these vehicles, the validity of the SmartKey with KEYLESS-GO is checked every time you pull a door handle.

To prevent possible malfunction, avoid exposing the SmartKey with KEYLESS-GO to high levels of electro- magnetic radiation.

If the SmartKey with KEYLESS-GO* is valid, your vehicle unlocks 앫 the doors 앫 the trunk lid

Warning!

When leaving the vehicle, always remove the SmartKey from the starter switch, take the SmartKey with KEYLESS-GO with you and lock the vehicle. Do not leave children unat- tended in the vehicle, or with access to an unlocked vehicle. Unsupervised use of vehi- cle equipment may cause an accident and/or serious personal injury.

You can also open and close the power windows (컄 page 212) and slid- ing/pop-up roof* (컄 page 216) using the SmartKey.

If the vehicle has been parked for a longer period of time, you must pull the door handle in order to activate the KEYLESS-GO function.

Important notes on using KEYLESS-GO* 앫 You can also use the SmartKey with KEYLESS-GO like a normal SmartKey (컄 page 86).

앫 You can combine KEYLESS-GO func-

tions with normal SmartKey functions (e.g. unlocking with KEYLESS-GO and locking with the remote control). 앫 Always carry the SmartKey with

KEYLESS-GO with you.

앫 Never store the SmartKey with

KEYLESS-GO together with: 앫 electronic items such as a cellular phone or another SmartKey with KEYLESS-GO

앫 metallic objects such as coins or

metal foil

Doing so could impair the function of the KEYLESS-GO system.

앫 To lock or unlock the vehicle, the

SmartKey with KEYLESS-Go must be lo- cated outside the vehicle within ap- proximately 3 ft (1 m) of a door or the trunk.

앫 In order to start the engine with the

SmartKey with KEYLESS-GO: 앫 the SmartKey with KEYLESS-GO

must be located in the vehicle

앫 all the doors must be closed 앫 the brake pedal must be depressed 앫 If you have started the engine with the

KEYLESS-GO start/stop button, you can only turn it off again with this but- ton, even if you have put the SmartKey in the starter switch in the meantime.

앫 This does not apply if, after starting, the gear selector lever is still in position P. and the SmartKey is then inserted in the starter switch. The SmartKey will then have priority over the KEYLESS-GO function and the vehicle’s electrical system will operate accord- ing to the position of the SmartKey in the starter switch, even stopping the engine.

앫 If the SmartKey with KEYLESS-GO is positioned farther away from the vehi- cle the system may no longer recognize the SmartKey with KEYLESS-GO. The vehicle cannot be locked or the engine started via the KEYLESS-GO system.

Controls in detail Locking and unlocking

앫 If the SmartKey with KEYLESS-GO is re- moved from the vehicle while the igni- tion is switched on (e.g. if passenger exits the vehicle with the SmartKey with KEYLESS-GO), the message Key not recognized! will appear in the multifunction display. Find the SmartKey with KEYLESS-GO or change its present location immediate- ly (e.g. place it on the front passenger seat or insert it in shirt pocket).

앫 Remember that the engine can be started by anyone with a SmartKey with KEYLESS-GO that is left inside the vehicle. If you leave the SmartKey with KEYLESS-GO behind when exiting and locking the vehicle, the message Key recognized in vehicle! will appear in the multifunction display.

Keep the area around head restraints clear of articles (e.g. clothing) to not obstruct the folding operation of the head restraints.

1 Head restraint release button 왘 Start the engine. 왘 Press the symbol-side on the rocker

switch 1 to release the head re- straints. The head restraints will fold backward.

Removing and installing rear seats head restraints

Warning!

For your protection, drive only with properly positioned head restraints.

Adjust head restraint so that the center of the head restraint supports the back of the head at eye level. This will reduce the poten- tial for injury to the head and neck in the event of an accident or similar situation.

Do not drive the vehicle without the seat head restraints. Head restraints are intend- ed to help reduce injuries during an acci- dent.

Prior to operating the vehicle, the driv- er should check and adjust the seat height, seat position fore and aft, and seat backrest angle if necessary, to en- sure adequate control, reach and com- fort. The head restraint should also be adjusted for proper height. See also the section on airbags (컄 page 59) for proper seat positioning. In addition, adjust the steering wheel to ensure adequate control, reach, opera- tion and comfort. Both the interior and exterior rear view mirrors should be ad- justed for adequate rear vision. Fasten seat belts. Infants and small children should be seated in a properly secured restraint system that complies with U.S. Federal Motor Vehicle Safety Standards 213 and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2.

Coolant temperature indicator

Warning!

앫 Driving when your engine is badly over-

heated can cause some fluids which may have leaked into the engine com- partment to catch fire. You could be se- riously burned.

앫 Steam from an overheated engine can cause serious burns and can occur just by opening the hood. Stay away from the engine if you see or hear steam com- ing from it.

Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

Excessive coolant temperature triggers a warning in the multifunction display (컄 page 323) and the red coolant warn- ing lamp in the instrument cluster comes on (컄 page 309).

During severe operating conditions, e.g. stop-and-go traffic, the coolant tempera- ture may rise close to 120°C. The engine should not be operated with the coolant temperature above 120°C. Do- ing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.
