Be careful that floor mats or carpets in the driver’s footwell have sufficient clear- ance for the pedals. During sudden driving or braking maneuvers the objects could get caught between the pedals. You could then no longer brake or accelerate.Warning! G Always fasten your seat belt before driving off. Always make sure your passengers are properly restrained, even those sitting in the rear and pregnant women. Failure to wear and properly fasten and po- sition your seat belt greatly increases your risk of injuries and their likely severity in an accident.

You and your passenger should al- ways wear seat belts. 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 wearing your seat belt.

The airbags can only protect as ex- pected if the occupants are using their seat belts ( page 61). G Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart TM compatible child seat, which operates with the BabySmart TM system installed in the ve- hicle to deactivate the passenger side front airbag when it is properly installed. Other- wise they will be struck by the airbag when it inflates in a crash. If this happens, serious or fatal injury will result. According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seat- ing positions.

Infants and small children must ride in back seats and be seated in an appropriate infant or child restraint system, which is properly secured with the vehicle’s seat belt and top tether strap, or secured via lower anchors and top tether strap, fully in accordance with the child seat manufactur- er’s instructions. A child’s risk of serious or fatal injuries is. 42 Getting startedDriving 1Latch plate 2Buckle 3Release button With a smooth motion, pull the belt from the belt outlet.  Place the belt over your shoulder.  Push latch plate1 into buckle2 until it clicks.

Significantly increased if the child restraints are not properly secured in the vehicle and the child is not properly secured in the child restraint.Warning! G Never ride in a moving vehicle with the seat backrest reclined. Sitting in an excessively reclined position can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the 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 re- straint when the wearer is in an upright po- sition and the belt is properly positioned on the body.

G Never let more people ride in the vehicle than there are seat belts available. Be sure everyone riding in the vehicle is correctly re- strained with a separate seat belt - even those in the rear.Warning! G Read and observe the additional warning no- tices printed in the “Safety and Security” section ( page 61). 43 Getting started Driving  If necessary, tighten the lap portion to a snug fit by pulling shoulder portion up.

Seat belt height adjustment Adjust seat belt so that shoulder portion is located as close as possible to the middle of your shoulder (it should not touch the neck). Front seats 4Button for belt outlet height adjust- ment  Press button4 and slide belt outlet up- ward or downward.Proper use of seat belts  Do not twist the belt when fastening.  Adjust seat belt so that the shoulder portion is located as close as possible to the middle of the shoulder (it should not touch the neck or pass under the arm). For this purpose, you can adjust the height of the belt outlet.  Position the lap belt as low as possible on your hips (over hip joint) and not across the abdomen.  Place the seat backrest in a nearly up- right position.

 Never use a seat belt for more than one person at a time.  Do not fasten a seat belt around a per- son and another object at the same time.

 Check your seat belt during travel to ensure that it is properly positioned.  Ensure that the seat belt is always fit- ted snugly.

You should avoid wearing bulky clothing, such as winter coats, when traveling in the vehicle.Warning! G Do not pass belts over sharp edges. They could tear.

Do not allow the belt to get caught in the door or in the seat adjustment mechanism. This could damage the belt. Never attempt to make modifications to seat belts. This could impair the effective- ness of the belts. Damaged seat belts or belts that were highly stressed in an accident must be replaced by an authorized Mercedes-Benz Center. 44 Getting startedDrivingStarting the engine Manual transmission Gearshift pattern for manual transmission Make sure that the gearshift lever is in Neutral position.

Once the vehicle is in motion, the auto- matic central locking system engages and the locking knobs drop down.After a cold start, the automatic transmis- sion engages at a higher revolution. This al- lows the catalytic converter to reach its operating temperature earlier. More information on driving can be found in the “Operation” section ( page 223).
