G 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 opening the engine hood. Stay away from the engine if you see or hear steam coming from it.

Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

! If the coolant temperature exceeds 248 ‡(120 †) do not continue driving. The engine will

otherwise be damaged.

Tires

Problem

USA only:

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

Canada only:

The yellow tire pressure monitor warning lamp (pressure loss) is lit.

USA only:

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

Possible causes/consequences and M Solutions

G Risk of accident

The tire pressure monitor has detected a loss of pressure in at least one of the tires.

X Stop the vehicle without making any sudden steering or braking maneuvers. Pay attention to the traffic conditions as you do so.

X Observe the additional display messages in the multifunction

display.

X Check the tire pressure. If necessary, correct the tire pressure

(Y page 359).

X If necessary, change a wheel (Y page 374).

The tire pressure monitor is faulty.

X Observe the additional display messages in the multifunction

display.

X Visit a qualified specialist workshop.

G WARNING Each tire, including the spare (if provided), should be checked at least every two weeks when cold and inflated to the 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 pressure label on the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated on the Tire and Loading Information placard or the tire pressure label, you should determine the proper tire 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 telltale when one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure telltale 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 telltale.

USA only:

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 telltale. When the system detects a malfunction, the telltale will flash for approximately 1 minute and then remain continuously illuminated. This sequence will be repeated every time

Warning and indicator lamps in the instrument cluster

281

the vehicle is started as long as the malfunction exists. When the malfunction indicator is illuminated, 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 telltale 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.

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 362).

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 362).

Further information can be found in the "Loading the vehicle" section (Y page 362).

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.

Ralways place the load behind unoccupied

seats if possible.

Rsecure the load with sufficiently strong and wear-resistant tie down. pad sharp edges for protection.

Important safety notes

G WARNING In order to help prevent spilling liquids on vehicle occupants and/or vehicle equipment, only use containers that fit into the cup holder. Use lids on open containers and do not fill containers to a height where the contents, especially hot liquids, could spill during braking, vehicle maneuvers, or in an accident. Liquids spilled on vehicle occupants may cause serious personal injury. Liquids

294 Features

spilled on vehicle equipment may cause damage not covered by the Mercedes-Benz Limited Warranty.

When not in use, keep the cup holder closed. An open cup holder may cause injury to you or others when contacted during braking, vehicle maneuvers, or in an accident.

Keep in mind that objects placed in the cup holder may come loose during braking, vehicle maneuvers, or in an accident and be thrown around in the vehicle interior. Objects thrown around in the vehicle interior may cause an accident and/or serious personal injury.

G WARNING Do not transport any heavy, sharp-edged or fragile bottles in the stowage compartments.

In the event of an accident, the stowage compartments cannot secure the bottles adequately. You and/or other vehicle occupants could be injured.

The stowage compartments in the doors have space for bottles containing up to 34 fl. oz. (1.0 l).

The bottles are neither secured in position nor prevented from tipping over. Therefore, do not place any open drink containers in the stowage compartments.
