Rear seat adjustment

Warning!

Warning!

Warning!

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

Adjust the head restraint so that it is close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the potential for injury to the head and neck in the event of an accident or similar situation.

You cannot remove the active head restraints on the driver’s and front passen- ger’s seat. For removal of the active head restraints we recommend that you contact an authorized Mercedes-Benz Light Truck Center. For information on head restraint adjust- ment, see “Seats” (컄 page 43). For information on active head restraints, see “Active head restraints” (컄 page 86).

According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seat- ing position. Thus, we strongly recommend that children be placed in the rear seats. Re- gardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant or toddler restraint, or booster seat recom- mended for the size and weight of the child. For additional information, see “Children in the vehicle” (컄 page 87). A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and the child is not properly secured in the child restraint.

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 belt would apply force at the abdomen or neck. That could cause serious or fatal injuries. The seat backrest and seat belts provide the best restraint when the wearer is in a nearly upright position and belts are properly positioned on the body.

Your seat must be adjusted so that you can correctly fasten your seat belt (컄 page 50). Never place hands under the seat or near any moving parts while a seat is being adjusted.

Tachometer

Outside temperature indicator

Make sure you are viewing the trip odometer display (컄 page 157). 왘 If it is not displayed, press button è or ÿ on the multifunction steering wheel (컄 page 158) repeatedly until the trip odometer appears in the multi- function display.

왘 Press and hold reset button 2

(컄 page 154) until the trip odometer is reset.

The red marking on the tachometer (컄 page 29) denotes excessive engine speed.

! Avoid driving at excessive engine speeds, as it may result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty.

To help protect the engine, the fuel supply is interrupted if the engine is operated within the red marking.

Warning!

The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose.

Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges.

The outside temperature is indicated in the multifunction display (컄 page 157).

155

Controls in detail Instrument cluster

The outside temperature sensor is located in the front bumper area. Due to its loca- tion, the sensor can be affected by road or engine heat during idling or slow driving. This means that the accuracy of the dis- played temperature can only be verified by comparison to a thermometer placed next to the sensor, not by comparison to exter- nal displays (e.g. bank signs etc.). When moving the vehicle into colder ambient temperatures (e.g. when leaving your garage), you will notice a delay before the lower temperature is displayed. A delay also occurs when ambient temper- atures rise. This prevents inaccurate temperature indications caused by heat radiated from the engine during idling or slow driving.

A driver’s attention to the road and traffic conditions must always be his/her primary focus when driving.

For your safety and the safety of others, selecting features through the multifunction steering wheel should only be done by the driver when traffic and road conditions permit it to be done safely.

Bear in mind that at a speed of just 30 mph (approximately 50 km/h), your vehicle is covering a distance of 44 feet (approximately 14 m) every second.

Depending on the selected menu, pressing the buttons on the multifunction steering wheel will alter what appears in the multi- function display. The information available in the multifunc- tion display is arranged in menus, each containing a number of functions or sub- menus. The individual functions are then found within the relevant menu (radio or CD operations under AUDIO, for example). These functions serve to call up relevant information or to customize the settings for your vehicle.

It is helpful to think of the menus, and the functions within each menu, as being ar- ranged in a circular pattern. 앫 If you press button è or ÿ
