Tires Problem

USA only: The yellow tire pressure monitor warning lamp (pressure loss/ malfunction) is lit.

USA only: The yellow tire pressure monitor warning lamp (pressure loss/ malfunction) flashes for 60 seconds and then remains lit.

G WARNING Each tire, including the spare (if provided), should be checked every other week when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the Tire and Loading Information placard on the driver's door B-pillar or, if available, the tire inflation pressure label on the inside of the fuel filler flap. If your vehicle has tires of a different size than the size

266 Warning and indicator lamps in the instrument cluster

indicated on the Tire and Loading Information placard or, if available, the tire inflation pressure label, you should determine the proper tire inflation pressure for those tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure warning lamp when one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure warning lamp illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure warning lamp. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure warning lamp. When the system detects a malfunction, the warning lamp will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is lit, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction warning lamp after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.

Loading guidelines

G WARNING Always fasten items being carried as securely as possible. Use cargo tie-down rings and fastening materials appropriate for the weight and size of the load. In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle. This can cause injury to vehicle occupants unless the items are securely fastened in the vehicle. To help avoid personal injury during a collision or sudden maneuver, exercise care when transporting cargo. Do not pile luggage or cargo higher than the seat backrests. The cargo compartment is the preferred place to carry objects. Always use cargo tie-down rings, and if so equipped, always use the cargo net when transporting cargo. Never drive a vehicle with the tailgate open. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death.

The gross vehicle weight (GVW) is the vehicle weight including fuel, vehicle tool kit, spare wheel, installed accessories, vehicle occupants and luggage/cargo. The gross load limit and the gross vehicle weight rating (GVWR) for your vehicle must

never be exceeded. The gross load limit and the GVWR are specified on the vehicle identification plate on the B-pillar of the driver's door (Y page 349). The load must also be distributed so that the weight on each axle never exceeds the gross axle weight rating (GAWR) for the front and rear axles. The specifications for GVWR and GAWR are on the vehicle identification plate on the B-pillar of the driver's door (Y page 349). Further information can be found in the "Loading the vehicle" section (Y page 349). The handling characteristics of a laden vehicle are dependent on the distribution of the load within the vehicle. For this reason, you should observe the following notes when transporting a load: Rposition heavy loads as far forwards as possible and as low down in the cargo compartment as possible.

Rthe load must not protrude above the upper

edge of the seat backrests.

Ralways place the load against the rear or front seat backrests. Make sure that the seat backrests are securely locked into place.

Cargo net Important safety notes G WARNING Make sure the cargo net is properly engaged at top and bottom position and the tightening belts are securely fastened. Never use a damaged cargo net. Always use cargo net when transporting cargo. This helps to avoid personal injury from smaller objects being thrown around in the occupant compartment during a collision or sudden maneuver.

The cargo net cannot prevent the movement of large, heavier objects into the passenger compartment in an accident. Such items must be properly secured using the cargo tie-down rings in the cargo compartment floor. Passenger use of seats behind installed cargo net is restricted because of the footwell being taken up by the net.

It is particularly important to use a safety net if the vehicle is loaded with small objects above the level of the backrests. For safety reasons, always use a cargo net when transporting loads.

Preparing the cargo net The cargo net can be used in two different positions (behind the B-pillar or the C-pillar).

RThe brackets behind B-pillar : are required for the cargo compartment enlargement (Y page 270). The corresponding cargo tie down rings to tighten the net are located in the footwell of the rear bench seat (Y page 272). RThe brackets behind C-pillar ; are

required for the cargo compartment behind the 2nd row of seats. The corresponding cargo tie down rings for tensioning the net are in the cargo compartment or on the backrests of the folded-down 3rd row of seats (Y page 272).

Roof carrier Important safety notes G WARNING Only use carriers when the crossbars have been completely mounted. The left and right roof rails are only stabilized by means of the crossbars mounted. Follow the manufacturer's installation instructions. Otherwise, an improperly attached carrier or its load could become detached from the vehicle. Do not exceed the maximum roof load of 198 lb (90 kg). Take into consideration that when the roof is loaded, the handling characteristics are different from those when operating the vehicle without the roof loaded.

! Mercedes-Benz recommends that you

only use roof carriers that have been tested and approved for Mercedes-Benz vehicles. This helps to prevent damage to the vehicle. Position the load on the roof carrier in such a way that the vehicle will not sustain damage even when it is in motion. Depending on the vehicle equipment, ensure that when the roof carrier is installed you can: Rraise the sliding sunroof fully Ropen the tailgate fully

Attaching the roof carrier

278 Stowage areas

X Secure the roof carrier to roof rails :. X Observe the manufacturer's installation

instructions.

Cross bar Points to observe before use The maximum roof load that can be used with additional accessories decreases by the dead weight of the crossbars (13.7 lbs/6.2 kg). ! Note that installing the crossbar

increases the vehicle height by 50 mm compared to the height stated in the "Technical data" section.

The wrench and the Allen key are located with the vehicle tool kit in the stowage space underneath the trunk floor (Y page 314). i Replacement parts are available as

Mercedes-Benz accessories. Contact your authorized Mercedes-Benz Service Center.

Installing the crossbars G WARNING Please follow these installation instructions carefully. Caution should be exercised to avoid damage to the vehicle while installing the crossbars. Also, be careful not to injure yourself or others while installing and adjusting the crossbars or loading items on them. Each individual step of the installation instructions, the warning notices, the general safety precautions and the instructions for use must be followed exactly. If the crossbars are not mounted correctly, they and the objects attached to them could come loose from your vehicle and cause an accident, thereby injuring you and other persons and/ or causing damage to property, including damage to your vehicle. G WARNING Every time the crossbars are mounted, before you set off on a journey and periodically during longer journeys, check all the screws

on the crossbars to make sure that they are secure, and tighten them if necessary. Repeat these checks at regular intervals as road- surface conditions dictate, and at least after every 1500 miles (2500 km) of continuous use. Otherwise, the crossbars, mounted accessories and the objects attached to them could come loose from the vehicle causing an accident, thereby injuring you and other persons and/or causing damage to property, including damage to your vehicle. Do not use lubricant on the screws of the crossbars. The screws could work loose and the crossbars could become detached from your vehicle, together with the objects attached to them causing an accident, thereby injuring you and other persons and/ or causing damage to property, including damage to your vehicle. G WARNING Only install the crossbars at the exact locations designated on the roof rails. The designated locations for the front crossbars are between the markings engraved on the inside of the roof rails. The designated locations for the rear crossbars are between the gaps on the roof rails. Otherwise, the crossbars, mounted accessories and the objects attached to them could come loose from the vehicle causing an accident, thereby injuring you and other persons and/or causing damage to property, including damage to your vehicle. G WARNING A roof load creates a greater surface area exposed to the wind and causes the vehicle to have a higher center of gravity, thereby changing the vehicle's driving characteristics. Accordingly, the additional weight on the roof of the vehicle can have a detrimental effect on braking, cornering and acceleration. Never exceed the maximum permissible roof load or the maximum permissible vehicle

Stowage areas

279

weight, even when accessories for the crossbars (e.g. ski racks, bicycle racks, etc.) are being used. Overloading the vehicle could result in an accident. When calculating the weight placed on the roof please make sure to add the weight of the crossbars, accessory racks and the load carried together. Always adapt your driving style to the road, traffic and weather conditions, and drive with added caution when the roof is loaded. Always drive with extreme care when the carrier is loaded. Take into consideration that when the carrier is loaded, the handling characteristics are different from those when operating the vehicle without a carrier loaded. G WARNING Do not use accessories which have not been approved by Mercedes-Benz for use in conjunction with these crossbars. If non- approved accessories are used, these accessories and/or the objects attached to them could come loose from the vehicle, thereby injuring you and other persons and/ or causing damage to property, including damage to your vehicle.

! Have a second person assist you when installing the crossbars. Otherwise, the vehicle could be damaged.
