Practical hints What to do if …

Monitor the 75 indicator lamp on the center console (컄 page 29) and the multifunction display in the instrument cluster (컄 page 27) for the following: With the seat unoccupied and the ignition turned on, 앫 the 75 indicator lamp on the center console should illuminate and

remain illuminated, indicating that the OCS (컄 page 71) has deactivated the front passenger front air bag.

앫 the message Front Passenger Airbag Enabled See Operator’s Manual or the message Front Passenger Airbag Disabled See Operator’s Manual should not appear in the multifunction display at any time the seat is unoccupied. Wait at least 60 seconds for the system to complete the necessary check cycles and to make sure neither message appears in the multifunction display.

If above conditions are met, you can occupy the front passenger seat again. De- pending on the front passenger classification sensed by the OCS (컄 page 71), the 75 indicator lamp will remain illuminated or go out. If above conditions are not met, the system is not working properly. Have the sys- tem checked as soon as possible by an authorized Mercedes-Benz Center.

Warning!

If the 75 indicator lamp

remains out even after performing the above corrective steps, do not have any children 12 years old and under and other small

individuals use the front passenger seat un- til the system has been repaired.

365

Possible cause/conse- quence Front passenger front air bag is deactivated while driving even though an adult or someone larger than a small individual is occupying the front passenger seat. Forces acting on the seat may make the system sense a decrease in weight.

Possible solution

Stop the vehicle in a safe location as soon as possible and check the front passenger seat for the following: 왘 Switch off the ignition (컄 page 60). 왘 Have the front passenger vacate the seat and exit the vehicle. 왘 Adjust the seat in a height position (컄 page 42). 왘 Make sure that no objects which apply forces to the seat are

present (e.g. objects such as books, briefcases etc. lodged under- neath, behind or around the seat). Such forces may cause the sys- tem to sense that an occupant of a lesser weight than actually present is on the front passenger seat.

왘 Keep the seat unoccupied, close the front passenger door and turn

on the ignition (컄 page 38). (Continued on next page)

Practical hints Resetting activated head restraints

왔 Resetting activated head restraints If the active head restraint have been trig- gered in an accident, the head restraints must be reset. Otherwise, active head re- straint cannot offer any additional protec- tion in the event of another rear-end collision. You can tell that the head restraints have been activated when they have been moved forward and cannot be adjusted.

i For your convenience, we recommend that you have this work carried out by an authorized Mercedes-Benz Center. You will find the reset tool for manually operating the head restraints in the Mercedes-Benz vehicle literature pouch.

왘 Take the reset tool out of the

Mercedes-Benz vehicle literature pouch.

왘 Guide reset tool into center of head re- straint between head restraint cushion and rear head restraint cover.

Warning!

! Be careful not to damage upholstery.

For safety reasons, have the active head re- straints checked by an authorized Mercedes-Benz Center after a rear-end colli- sion.

왘 Press reset tool forward in direction of

arrow.

왘 Press reset tool downward until you

hear the head restraint release mechanism audibly engage.

왘 Pull out reset tool. 왘 Firmly press head restraint cushion

backward towards rear head restraint cover until it engages.

Warning!

When pushing back the head restraint cush- ion, take care that your fingers do not be- come caught between the head restraint cushion and the cover. Failing to do so may lead to injury.

왘 Repeat this procedure for second head

restraint.

For information on head restraint adjust- ment, see “Seats” (컄 page 41).

Practical hints Replacing SmartKey batteries

If the batteries in the SmartKey/SmartKey with KEYLESS-GO* are discharged, the ve- hicle can no longer be locked or unlocked. It is recommended to have the batteries re- placed at an authorized Mercedes-Benz Center.

Batteries contain materials that can harm the environment if disposed of improperly. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to accept old batteries for recycling.

Warning!

i When inserting the batteries, make sure they are clean and free of lint.

i When changing batteries, always replace both batteries. The required replacement batteries are available at any authorized Mercedes-Benz Center.

Replacement batteries: Lithium, type CR 2025 or equivalent. 왘 Remove the mechanical key out of the

SmartKey/SmartKey with KEYLESS-GO* (컄 page 398).

1 Mechanical key 2 Battery compartment 왘 Insert mechanical key 1 into opening. 왘 Press mechanical key 1 in direction of

arrow. The battery compartment is unlatched. 왘 Pull battery compartment 2 out of the

housing.

Batteries contain poisonous and corrosive substances. Therefore keep the batteries out of reach of children.

If a battery is swallowed, seek medical help immediately.

Warning!

SmartKey batteries contain Perchlorate ma- terial, which may require special handling and regard for the environment. Check with your local government’s disposal guidelines. California residents, see http://www.dtsc.ca.gov/HazardousWaste /Perchlorate/index.cfm.

i If the headlamps or front fog lamps are fogged up on the inside as a result of high humid- ity, driving the vehicle a distance with the lights on should clear up the fogging.

i Auxiliary bulbs will be brought into use when lamps malfunction. Read and observe the mes- sages in the multifunction display (컄 page 382).

Practical hints Replacing bulbs

Bulbs

Safe vehicle operation depends on proper exterior lighting and signaling. It is there- fore essential that all bulbs and lamp as- semblies are in good working order at all times. Correct headlamp adjustment is extremely important. Have headlamps checked and readjusted at regular intervals and when a bulb has been replaced. See your autho- rized Mercedes-Benz Center for headlamp adjustment.

Warning!

Bulbs and bulb sockets can be very hot. Al- low the lamp to cool down before changing a bulb.

Notes on bulb replacement 앫 Use only 12 volt bulbs of the same type

and with the specified watt rating.

앫 Switch lights off before changing a bulb

to prevent short circuits.

Keep bulbs out of reach of children.

앫 Always use a clean lint-free cloth when

handling bulbs.

앫 Your hands should be dry and free of oil

and grease.

앫 If the newly installed bulb does not light

up, contact an authorized Mercedes-Benz Center.

Halogen lamps contain pressurized gas. A bulb can explode if you: 앫 touch or move it when hot 앫 drop the bulb 앫 scratch the bulb Wear eye and hand protection.

Because of high voltage in Xenon lamps, it is dangerous to replace the bulb or repair the lamp and its components. We recommend that you have such work done by a qualified technician.

Have the LEDs and bulbs for the following lamps replaced by an authorized Mercedes-Benz Center: 앫 Additional turn signals in the exterior

rear view mirrors

앫 High mounted brake lamp 앫 Bi-Xenon* lamps 앫 Front fog lamps 앫 Front side marker lamps 앫 Parking and standing lamps (vehicles

with Bi-Xenon* headlamps only) 앫 Rear lamps (except license plate
