Important safety notes

WARNING
Always fasten your seat belt before driving off.

Always make sure all of your passengers are properly restrained. You and your passengers should always wear seat belts.

Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident.

If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed.

In the same crash, the possibility of injury or death is lessened if you are properly wearing your seat belt. The air bags can only protect as intended if the occupants are properly wearing their seat belts.

WARNING
Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide the best restraint when the wearer is in a position that is as upright as possible and the seat belt is properly positioned on the body.

WARNING
Never let more people ride in the vehicle than there are seat belts available. Make sure everyone riding in the vehicle is correctly restrained with a separate seat belt. Never use a seat belt for more than one person at a time.

WARNING
Always have damaged seat belts or seat belts that have been subjected to a load in an accident replaced and the anchorages checked.

Only use seat belts that have been approved by Mercedes-Benz.

Never tamper with seat belts. This can result in the unintended deployment of the Emergency Tensioning Devices or the failure to deploy when necessary.

Do not bleach or dye seat belts, as this may severely weaken them. In the event of a collision, they may be unable to provide adequate protection.

Have all work carried out only by qualified technicians. Consult a qualified specialist workshop.

The use of infant or child restraints is required by law in all 50 states, the District of Columbia, all U.S. territories and all Canadian provinces.

Even where this is not the case, all vehicle occupants should have their seat belts fastened when the vehicle is in motion.

See "Children in the vehicle"  for further information on infants and children traveling in the vehicle, as well as on child restraint systems.

Correct use of the seat belts

WARNING
CORRECT USE OF SEAT BELTS Seat belts only work properly if they are fastened correctly. Never wear seat belts in any other way than as described in this section, as that could result in serious injuries in the event of an accident.

All occupants should wear their seat belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, even if the vehicle overturns. The restraint system installed is equipped with SRS (driver's air bag, frontpassenger air bag, window curtain air bags), belt tensioners and belt force limiters.

The system is designed to enhance the protection offered to occupants who are wearing their seat belts correctly, in certain frontal impacts (front air bags and belt tensioners) and side impacts (window curtain air bags and belt tensioners) which exceed preset deployment thresholds.

Never route the shoulder section of the seat belt under your arm, across your neck or anywhere other than across your shoulder. In the event of a frontal impact, your body would be moved too far forward.

This would increase the risk of head and neck injuries. The seat belt would then apply excessive force to the ribs or abdomen which could cause severe internal injuries to organs such as the liver or spleen.

Adjust the seat belt so that the upper part of the belt is as close as possible to the center of the shoulder. It should not touch the neck. Never route the belt under the shoulder. The height of the belt outlet can be altered to ensure correct usage.

The lap belt should be routed as low as possible across the hips, not across the abdomen. If the lap belt is routed across the abdomen, it could cause serious injuries in the event of an impact.

Never route the seat belt over rigid or fragile objects in or on your clothing, such as eyeglasses, pens, keys etc, as this could cause injuries.

Always ensure that the seat belt is routed correctly. This is particularly important if you are wearing loose clothing.

Only one person should use each seat belt at any one time. Never use a seat belt to restrain more than one person or route the belt around additional objects.

Never wear seat belts when they are twisted. Otherwise, in the event of an impact, the full width of the seat belt is unavailable to distribute the force of the impact. The twisted seat belt routed across your body could cause injuries.

Pregnant women should also wear a threepoint seat belt. The lap belt must always pass across your lap as low down as possible, i.e. across your hips; not across your abdomen.

The seat backrest should be set as close to vertical as possible.

Check the seat belt during the journey in order to make sure that it is correctly positioned.

Never rest your feet on the dashboard or the seat. Always keep both feet on the floor in front of the seat.

When using a seat belt to secure an infant restraint system, child restraint system or a child on a booster seat, always follow the child seat manufacturer's instructions.

WARNING
Do not pass seat belts over sharp edges. They could tear.

Do not allow the seat belt to get caught in the door or in the seat adjustment mechanism.

This could damage the seat belt.

Never attempt to make modifications to seat belts. This could impair the effectiveness of the seat belts.

Fastening seat belts

Important safety notes

WARNING
According to accident statistics, children are safer when properly restrained on the rear seats than on the front-passenger seat. Thus, we strongly recommend that children be placed in the rear seat whenever possible.

Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriately sized child restraint system or booster seat recommended for the size and weight of the child. For additional information, see the "Children in the vehicle" section.

A child's risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/ or the child is not properly secured in the child restraint.

WARNING
Children 12 years old and under must never ride in the front seat, except in a Mercedes- Benz authorized BabySmart compatible child seat, which operates with the BabySmart system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result.

Emergency Tensioning Devices, belt force limiters

WARNING
Pyrotechnic ETDs that were activated must be replaced.

For your safety, when disposing of the pyrotechnic ETDs always follow our safety instructions. These are available at any authorized Mercedes-Benz Center.

If the front-passenger seat is not occupied, do not engage the seat belt tongue in the buckle on the frontpassenger seat. Otherwise, the Emergency Tensioning Device could be triggered in the event of an accident.

In order to ensure that the pyrotechnic Emergency Tensioning Devices have not been triggered, always have the seat belts checked after an accident.

If the Emergency Tensioning Devices have been triggered, they must be replaced.

The seat belts for the front seats and rear outer seats are equipped with ETDs and seat belt force limiters.

The ETDs on the driver's and front-passenger seat consist of pyrotechnic belt buckle tensioners and belt anchor installation tensioners that are triggered together. The belt buckle tensioner is mounted on the Bpillar and the belt anchor installation is mounted on the side of the seat. After deploying, both tensioners must always be replaced.

The ETDs tighten the seat belts in an accident, pulling them close against the body.

The ETDs do not correct incorrect seat positions or incorrectly fastened seat belts.

The ETDs do not pull vehicle occupants back towards the backrest.

When triggered, seat belt force limiters help to reduce the peak force exerted by the seat belt on the vehicle occupant.

The front seat belt force limiters are synchronized with the front air bags, which take on a part of the deceleration force. Thus, the force exerted on the occupant is distributed over a greater area.

The ETDs can only be activated when: the SmartKey is in position 1 or 2 in the ignition lock.> R the restraint systems are operational; see "SRS warning lamp" .> R the belt tongue is engaged in the buckle on each of the lap-shoulder belts in the front.> R the front-passenger seat is occupied and the belt tongue is engaged in the buckle on the front-passenger side

The Emergency Tensioning Devices are triggered depending on the type and severity of an accident, if:> R in the event of a head-on or rear-end collision, the vehicle decelerates or accelerates rapidly in a longitudinal direction during the initial stages of the impact> R if, in the event of a side impact, on the side opposite the impact the vehicle decelerates or accelerates rapidly in a lateral direction> R in certain situations where the vehicle overturns and the system determines that it can provide additional protection

If the ETDs are deployed, you will hear a bang, and a small amount of powder may also be released. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard. The 6 SRS warning lamp lights up.
