Hill-start assist system On uphill grades, the hill-start assist system maintains the pressure in the brake system for approximately 1 second after you have released the brake pedal. Therefore, you can start off smoothly without the vehicle moving immediately after releasing the brake pedal. G Warning! The hill-start assist system is not designed to function as a parking brake. It does not prevent the vehicle from moving when parked on an incline. Always engage the parking brake in addition to shifting the automatic transmission into park position P (manual transmission: shift into 1st gear or reverse gear R).

All-wheel drive (4MATIC) In vehicles with all-wheel drive (4MATIC), both axles are powered at all times when the vehicle is being operated. The 4MATIC improves traction in conjunction with the ESP® (Y page 62) and the Electronic Traction System (ETS/4-ETS) (Y page 63). G Warning! If a drive wheel is spinning due to insufficient traction: RWhile driving off, apply as little throttle as

possible.

RWhile driving, ease up on the accelerator

pedal.

RAdapt your speed and driving style to the

prevailing road conditions.

Failure to observe these guidelines could cause the vehicle to skid. The 4MATIC cannot prevent accidents resulting from excessive speed.

! Do not tow with one axle raised. Doing so could damage the transfer case, which is not covered by the Mercedes-Benz Limited Warranty. All wheels must be on or off the

Parktronic system (Parking assist) This feature is only available in Canada vehicles. The Parktronic system is an electronic parking aid with ultrasonic sensors designed to assist the driver during parking maneuvers. The Parktronic system indicates the relative distance between the vehicle and an obstacle visually and audibly. The Parktronic system is activated automatically when Ryou switch on the ignition

and

Ryou release the parking brake

and

Rvehicles with automatic transmission: the automatic transmission is in drive position D, reverse gear R, or neutral position N

The Parktronic system deactivates at speeds above approximately 11 mph (18 km/h). At lower speeds, the Parktronic system activates again. The Parktronic system also deactivates when you shift the automatic transmission into park position P or engage the parking brake. The Parktronic system monitors the surroundings of your vehicle with six sensors in the front bumper and four sensors in the rear bumper.

scratch or damage sensors :, see “Cleaning the driving systems sensors” (Y page 263). G Warning! The Parktronic is a supplemental system. It is not intended to, nor does it replace, the need for extreme care. The responsibility during parking and other critical maneuvers always remains with the driver. G Warning! Make sure no persons or animals are in or near the area in which you are parking/ maneuvering. Otherwise, they could be injured.

! Special attention must be paid to objects

with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, elevated crossbars or road curbs). Such objects may not be detected by the system and can damage the vehicle. During parking maneuvers, pay special attention to objects located above or below the height of the sensors (e.g. street curbs, painted posts, or trailer hitches etc.). The Parktronic system will not detect such objects at close range and damage to your vehicle or the object may result.

! Ultrasonic signals from outside sources

(e.g. truck air brakes, car wash, or jackhammers) may impair the operation of the Parktronic system.

Loading and storing Loading instructions G Warning! Always fasten items being carried as securely as possible using 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 trunk is the preferred place to carry objects. Do not place anything on the rear- window shelf. Never drive a vehicle with the trunk open. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death.

Load distribution

The total load weight including vehicle occupants and luggage/cargo should not exceed the total load limit indicated on the corresponding Tire and Loading Information placard located on the driver’s door B-pillar (Y page 238). The handling characteristics of a fully loaded vehicle depend greatly on the load distribution. It is therefore recommended to load the vehicle according to the illustration shown. The heaviest items are to be placed towards the front of the vehicle. i The enlarged cargo area should only be used for items which do not fit in the trunk alone.

Please pay attention to and comply with the following instructions when loading the vehicle and transporting cargo: RAlways place items being carried against front or rear seat backrests, and fasten them as securely as possible.

RThe heaviest portion of the cargo should always be kept as low as possible against front or rear seat backrests.
