2007 Mercedes-benz M Class Owners Manual

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 last 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. Depending on the front passenger classification sensed by the OCS (컄 page 85), the 59 indicator lamp will remain illuminated or go out. If above conditions are not met, the system is not working properly. Have the system checked as soon as possible by an authorized Mercedes-Benz Light Truck Center.

Warning!

If the 59 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 until the system has been repaired.

441

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 Apply the parking brake (컄 page 65). 왘 Switch off the ignition (컄 page 40). 왘 Have the front passenger vacate the seat and exit the vehicle. 왘 Adjust the seat in a height position (컄 page 44). 왘 Make sure that no objects which apply forces to the seat are present (e.g. objects such as books, briefcases etc. lodged underneath, behind or around the seat). Such forces may cause the system 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 switch

on the ignition (컄 page 40).

Possible cause/consequence Possible solution

왘 Observe the coolant temperature in the

multifunction display (컄 page 154). If the temperature raises again:

왘 Contact an authorized Mercedes-Benz

Light Truck Center immediately.

During severe operation conditions and stop-and-go city traffic, the coolant tem- perature may rise close to 248°F (120°C).

! The engine should not be operated with the coolant temperature above 248°F (120°C). Doing so may cause serious damage which is not covered by the Mercedes-Benz Limited Warranty.

Warning!

Driving when your engine is overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned.

Steam from an overheated engine can cause serious burns which can occur just by open- ing the engine hood. Stay away from the en- gine if you see or hear steam coming from it.

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

Possible cause/consequence Possible solution The coolant level is too low.

왘 Add coolant (컄 page 362). 왘 If you have to add coolant frequently,

have the cooling system checked by an authorized Mercedes-Benz Light Truck Center.

! Do not ignore the low engine coolant level warning. Extended driving with the message and symbol displayed may cause serious engine damage not covered by the Mercedes-Benz Limited Warranty. Do not drive without sufficient amount of coolant in the cooling system. The engine will overheat causing major engine damage.

앫 Do not remove pressure cap on coolant

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

앫 Using a rag, slowly open the cap approx- imately 1/2 turn to relieve excess pres- sure. If opened immediately, scalding hot fluid and steam will be blown out un- der pressure.

앫 Do not spill antifreeze on hot engine

parts. Antifreeze contains ethylene gly- col which may burn if it comes into con- tact with hot engine parts.

Warning!

Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. You could be seriously burned.

Warning!

In order to avoid potentially serious burns: 앫 Use 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 gauge indi- cates that the coolant is overheated.

! Vehicles with factory-mounted running-boards*: Your vehicle is equipped with a scissors-type jack (located under the cargo compartment floor) designed for use with factory-mounted running boards. Only use this jack when jacking up vehicles with factory-mounted running boards as otherwise the vehicle’s underbody can be damaged. See separate instructions for scis- sors-type jack.

Vehicle jack

Warning!

The vehicle jack is located underneath the cargo compartment floor.

The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into both sides of the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack.

Do not disengage the parking brake while the vehicle is raised. Be certain that the jack is always vertical (plumb line) when in use, especially on hills. Always try to use the jack on a level surface.

Make sure that the jack arm is fully seated in the jack take-up bracket. Always lower the vehicle onto jackstands of sufficient capacity before working under the vehicle.

Warning!

The dimensions of the Minispare wheel are different from those of the road wheels. As a result, the vehicle handling characteristics change when driving with a Minispare wheel mounted. Adapt your driving style accord- ingly.

The Minispare wheel is for temporary use only. When driving with a Minispare wheel mounted, ensure proper tire inflation pressure and do not exceed a vehicle speed of 50 mph (80 km/h).

Drive to the nearest Mercedes-Benz Light Truck Center as soon as possible to have the Minispare wheel replaced with a regular road wheel.

Never operate the vehicle with more than one spare wheel mounted. Do not switch off the ESP® when a Minispare wheel is mounted.

왔 Resetting activated head restraints If the active head restraints have been trig- gered in a rear-end collision, the active head restraints must be reset. Otherwise, the active head restraints cannot offer any additional protection in the event of anoth- er rear-end collision. You can tell that the head restraints have been activated when they have been moved forward and cannot be adjusted.

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.

! Be careful not to damage upholstery.

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

Warning!

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

Practical hints Replacing SmartKey batteries

If the batteries in the SmartKey or the SmartKey with KEYLESS-GO* are dis- charged, the vehicle can no longer be locked or unlocked. It is recommended to have the batteries replaced at an autho- rized Mercedes-Benz Light Truck Center.

Warning!

Keep the batteries out of reach of children.

If a battery is swallowed, seek medical help immediately.

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

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.

Warning!

Bulbs and bulb sockets can be very hot. Allow the lamp to cool down before chang- ing a bulb.

Notes on bulb replacement 앫 Only use 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.
