Cruise control

The cruise control automatically maintains the speed you set for your vehicle. The use of cruise control is recommended for driving at a constant speed for extend- ed periods of time. You can set or resume cruise control at any speed above 20 mph (30 km/h). The cruise control function is operated by means of the cruise control lever. The cruise control lever is the uppermost lever on the left-hand side of the steering column (컄 page 24).

왔 Driving systems The driving systems of your vehicle are described on the following pages: 앫 Cruise control (컄 page 257) and

Distronic* (컄 page 262), with which the vehicle can maintain a preset speed.

앫 Distance warning function*

(컄 page 275) is only available with Distronic*, which warns of stationary obstacles or slower moving vehicles that you are closing in on too quickly. 앫 AIRMATIC* (컄 page 276) adjusts the

vehicle suspension characteristics automatically and controls the vehicle level.

앫 Parktronic* (컄 page 281) and rear view camera* (컄 page 285), which serve as a parking aid.

For information on the ABS, BAS, EBP, ESP®, and 4-ETS, see “Driving safety sys- tems” (컄 page 99).

Controls in detail Driving systems

Warning!

The cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always remain responsible for the vehicle’s speed and for safe brake operation.

Only use the cruise control if the road, traffic and weather conditions make it advisable to travel at a constant speed. 앫 The use of the cruise control can be

dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a constant speed.

앫 The use of the cruise control can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control.

앫 Deactivate the cruise control when

driving in fog.

The “Resume” function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed.

257

Controls in detail Driving systems

Warning!

The cruise control brakes automatically so that the set speed is not exceeded. The brake pedal depresses automatically when the cruise control engages the brakes.

Keep driver’s foot area clear at all times, including the area under the brake pedal. Objects stored in this area may impair pedal movement which could interfere with the braking ability of the cruise control system.

Do not place your foot under the brake pedal – your foot could become caught.

Keep in mind that the cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always remain responsible for the vehicle’s speed and for safe brake operation.

258

Activating cruise control You can activate the cruise control when the vehicle speed is above 20 mph (30 km/h). In the following cases you cannot activate the cruise control: 앫 when you brake 앫 when you have set the parking brake 앫 when the automatic transmission is set

Distronic* (Canada only)

The Distronic is available on the R 550 4MATIC only. When activated, the Distronic adaptive cruise control system increases the driving convenience afforded by the cruise control while traveling on expressways and other major roadways. 앫 If the Distronic distance sensor detects a slower moving vehicle directly ahead, your vehicle speed will be reduced so that you follow that vehicle at your preset following distance.

앫 If there is no vehicle directly ahead of you, Distronic will function in the same way as standard cruise control (컄 page 257).

Warning!

Warning!

Warning!

Controls in detail Driving systems

Distronic is a convenience system. Its speed adjustment reduction capability is intended to make cruise control more effective and usable when traffic speeds vary. It is not however, intended to, nor does it, replace the need for extreme care. The responsibility for the vehicle’s speed, distance to the preceding vehicle and, most importantly, brake operation to ensure a safe stopping distance, always remains with the driver.

Distronic cannot take road and traffic condi- tions into account.

Complex driving situations are not always fully recognized by Distronic. This could result in wrong or missing distance warnings.

Distronic adaptive cruise control is no substitute for active driving involvement. It does not react to pedestrians or on station- ary objects, nor does it recognize or predict the lane curvature or the movement of preceding vehicles.

Distronic can only apply a maximum of 20% of the vehicle’s braking power.

It is the driver’s responsibility at all times to be attentive to the road, weather and traffic conditions. Additionally, the driver must provide the steering, braking and other driving inputs necessary to remain in control of the vehicle.

High-frequency sources such as toll stations, speed measuring systems etc. can cause the Distronic system to malfunction.

Distronic requires familiarity with its opera- tional characteristics. We strongly recom- mend that you review the following information carefully before operating the system.

Warning!

Distronic cannot take road and traffic condi- tions into account. Only use Distronic if the road, weather and traffic conditions make it advisable to travel at a constant speed.

Warning!

Use of Distronic can be dangerous on slip- pery roads. Rapid changes in tire traction can result in wheel spin and loss of control. 컄컄

263

Controls in detail Driving systems

컄컄

Distronic does not act upon adverse sight and distance conditions. Do not use Distronic during conditions of fog, heavy rain, snow or sleet.

Warning!

Distronic cannot take weather conditions into account. Switch off Distronic or do not switch it on if: 앫 roads are slippery or covered with snow

or ice. The wheels could lose traction while braking or accelerating, and the vehicle could skid.

앫 the sensor is dirty or visibility is

diminished due to snow, rain or fog, for example. The distance control system functionality could be impaired.

Always pay attention to surrounding traffic conditions even while Distronic is switched on. Otherwise, you may not be able to recog- nize dangerous situations until it is too late. This could cause an accident in which you and others could be injured.

264

Switch off Distronic: 앫 when changing from the left to the right lane if vehicles are moving more slowly in the left lane

앫 when entering a turn lane or highway off

ramp

앫 in complex driving situations, such as in

highway construction zones

In these situations, Distronic will continue to maintain the set speed unless deactivated.

Distronic is designed and intended only to maintain a set speed and keep a set dis- tance from moving objects in front of it.

Warning!

The “Resume” function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed.

Warning!

Close attention to road and traffic condi- tions is imperative at all times, regardless of whether or not Distronic is activated.

Use of Distronic can be dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a continuous speed.

If Distronic calculates that there is a dan- ger of collision: 앫 The distance warning lamp l in the

instrument cluster comes on (컄 page 26).

앫 An intermittent warning sounds. 왘 Immediately apply the brake to avoid a

266

Warning!

Warning!

Distronic brakes your vehicle with a maxi- mum deceleration of 6.5 ft/s2 (2 m/s2). This corresponds to about 20% of the maximum deceleration of your vehicle.

Distronic brakes the vehicle in an effort to restore the preset distance or to maintain the set speed.

Keep driver’s foot area clear at all times, in- cluding the area under the brake pedal. Ob- jects stored in this area may impair pedal movement which could interfere with the braking ability of the Distronic system.

Do not place your foot under the brake pedal – your foot could become caught.

An intermittent warning sounds and the distance warning lamp l in the instru- ment cluster is illuminated if the Distronic system calculates that the distance to the vehicle ahead and your vehicle’s current speed indicate that Distronic will not be ca- pable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision.

Immediately brake the vehicle to increase your distance to the preceding vehicle. The warning sound is intended as a final caution in which you should intercede with your own braking inputs to avoid a potentially danger- ous situation. Do not wait for the operation of the warning signal to intercede with your own braking. This will result in potentially dangerous emergency braking which will not always result in an impact being avoided.

Tailgating increases the risk of an accident.

Controls in detail Driving systems

Warning!

Distronic switches off and releases the brakes when the vehicle decelerates below the minimum speed of 20 mph (30 km/h) by operation of the system. At that time the driver must apply the brakes in order to reduce vehicle speed further or bring it to a stop.

! Setting the automatic transmission to N while driving cancels the Distronic. However, the automatic transmission should not be set to N while driving except to coast when the vehicle is in danger of skidding (e.g. on icy roads).

i Depressing the accelerator pedal does not deactivate the Distronic. After a brief accelera- tion (e.g. for passing), the Distronic will resume the last set speed.

272

Warning!

It is up to the driver to exercise discretion to select the appropriate setting given road conditions, traffic, driver’s preferred driving style and applicable laws and driving recom- mendations for safe following distance.

Setting the following distance in Distronic You can set the specified following distance for Distronic by varying the time setting between 1.0 and 2.0 seconds. Us- ing this time setting and the current speed of your vehicle, Distronic calculates and sets the required following distance to the preceding vehicle. The set distance will be shown in the multifunction display (컄 page 267). The distance setting switch for the time setting is located on the cruise control lever on the left-hand side of the steering column.

1 Distance setting switch 2 To decrease distance 3 To increase distance

Increasing distance Increasing the distance setting tells Distronic to maintain a greater following distance to the preceding vehicle. 왘 Turn distance setting switch 1 in

direction of arrow 3.

Decreasing distance Decreasing the distance setting tells Distronic to maintain a shorter following distance to the preceding vehicle. 왘 Turn distance setting switch 1 in

direction of arrow 2.

Driving with Distronic This section describes a number of driving situations where special precaution is re- quired on the part of the driver. Be pre- pared to brake in such situations. Braking will deactivate the Distronic system.

Warning!

Distronic works to maintain the speed selected by the driver unless a moving obstacle proceeding directly ahead of it in the same travel direction is detected (e.g. following another vehicle ahead of you at your set distance). This means that: 앫 Your vehicle can pass another vehicle

after you have changed lanes.

앫 While in a sharp turn or if the preceding vehicle is in a sharp turn, Distronic could lose sight of the preceding vehicle. Your vehicle could then accelerate to the previously selected speed.

Controls in detail Driving systems

Distronic regulates only the distance be- tween your vehicle and those directly ahead of it, but does not register stationary objects in the road, e.g.: 앫 a stopped vehicle in a traffic jam 앫 a disabled vehicle 앫 an oncoming vehicle The driver must always be alert, observe all traffic and intercede as required by means of steering or braking the vehicle.

Warning!

Distronic should not be used in snowy or icy road conditions.

273

Turns and bends

Offset driving

In turns or bends, Distronic may not detect a moving vehicle in front, or it may detect one too soon. This may cause your vehicle to brake late or unexpectedly.

A vehicle traveling in your lane but offset from your direct line of travel may not be detected by Distronic. There will be insuffi- cient distance to the vehicle ahead.

Controls in detail Driving systems

The most likely cause for a malfunctioning system is a dirty sensor (located behind the hood grille), especially at times of snow and ice or heavy rain. In such a case, Distronic will switch off, and the message DISTRONIC Currently Unavailable See Operator’s Manual appears in the multi- function display. For cleaning and care of the Distronic sen- sor, see “Cleaning the Distronic* system sensor cover” (컄 page 407).

i If the message DISTRONIC Available Again appears during driving, the dirt (e.g. slush) has dissolved; Distronic works again, if you reactivate it (컄 page 268).

274

Lane changing

Narrow vehicles

Distronic has not yet detected the vehicle changing lanes. There will be insufficient distance to the lane-changing vehicle.

Because of their narrow profile, the vehi- cles traveling near the outer edges of the lane have not yet been detected by Distronic. There will be insufficient distance to the vehicles ahead.

Controls in detail Driving systems

Distance warning function* (Canada only)

When Distronic* is deactivated, this function will continue to warn you when recognizing a stationary obstacle or a slower vehicle moving in your vehicle’s path and the danger of a collision exists: 앫 The distance warning lamp l in the

instrument cluster comes on.

앫 An intermittent warning will sound if

necessary.

If these warnings are issued, you must brake manually to maintain a safe distance and avoid a collision with the preceding vehicle. When pressing the brake pedal, the warn- ing sound ceases. The warning sound will also cease when the distance to the preceding vehicle is sufficient again with- out applying the brakes. In this case, the distance warning lamp will also go out.

275

Controls in detail Driving systems

Warning!

If the distance warning lamp l in the in- strument cluster comes on while driving and/or an intermittent warning sounds, immediate attention on the part of the driver is required. As required by the traffic situation, apply the brakes and navigate around a possible obstacle. However, do not drive by relying on the distance warning function, as this will result in an emergency braking application. This will not always enable you to avoid a collision, especially when traveling on varying road surface conditions and with varying driver reaction.

Complex driving situations are not always fully recognized by the distance warning function. This could result in wrong or miss- ing distance warnings.

Permanent four-wheel drive (4MATIC)*

Your vehicle is equipped with permanent four-wheel drive (4MATIC). Both, the front and rear axles, are powered at all times when the vehicle is being operated. The 4MATIC improves traction in conjunction with the ESP® (컄 page 101) and the Electronic Traction System (컄 page 103).

Warning!

If a drive wheel is spinning due to insuffi- cient traction: 앫 While driving off, apply as little throttle

as possible.

앫 While driving, ease up on the accelera-

tor.

앫 Adapt 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 re- sulting from excessive speed.

! Operational or performance test must only be conducted on a two-axle dynamometer. If such tests are necessary, contact an authorized Mercedes-Benz Light Truck Center. You could otherwise seriously damage the brake system or the transfer case which is not covered by the Mercedes-Benz Limited Warranty.

! Because the ESP® operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO* start/stop button in position 0 or 1) when testing the parking brake on a brake test dynamometer and such testing should be no longer than 10 seconds. Active braking action through the ESP® may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.

i In winter operation, the maximum effective- ness of the 4MATIC is only achieved with winter tires (컄 page 398) or snow chains as required.

Parktronic* (Parking assist)

Warning!

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.

Special attention must be paid to objects with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, or road curbs). Such objects may not be detected by the system and can damage the vehicle.

The operational function of the Parktronic system can be affected by dirty sensors, especially at times of snow and ice, see “Cleaning the Parktronic* system sensors” (컄 page 408). Interference caused by other ultrasonic signals (e.g. working jackhammers, car wash, or the air brakes of trucks) can cause the system to send erratic indications, and should be taken into consideration.

281

Controls in detail Driving systems

Warning!

Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them.

The Parktronic system is an electronic aid designed to assist the driver during parking maneuvers. It visually and audibly indicates the relative distance between the vehicle and an obstacle. The Parktronic system is automatically activated when you 앫 switch on the ignition or start the

engine

and 앫 release the parking brake and 앫 set the automatic transmission to

position D, R, or N

282

The Parktronic system deactivates at vehicle speeds exceeding approximately 11 mph (18 km/h). At lower vehicle speeds, the Parktronic system turns on again. The Parktronic system also deactivates when you set the automatic transmission to position P or depress the parking brake pedal. The Parktronic system monitors the surroundings of your vehicle with six sen- sors in the front bumper and four sensors in the rear bumper.

Range of the sensors To function properly, the sensors must be free of dirt, ice, snow and slush. Clean the sensors regularly, being careful not to scratch or damaging the sensors, see “Cleaning the Parktronic* system sensors” (컄 page 408).

! During parking maneuvers, pay special attention to objects located above or below the height of the sensors (e.g. planters or trailer hitches). 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. working jackhammers, car wash or the air brakes of trucks) may impair the operation of the Parktronic system.
