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.

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.

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

to position P, R, or N

앫 if the ESP® is switched off 앫 if the ESP® has switched off due to a

malfunction

i The vehicle speed displayed in the speedom- eter can briefly vary from the speed setting for the cruise control system.

Setting current speed 왘 Accelerate or decelerate to the desired

speed.

왘 Briefly lift the cruise control lever in direction of arrow 1 or depress in direction of arrow 2. The current speed is set.

왘 Remove your foot from the accelerator

pedal. The cruise control is activated.

The current set speed appears in the multifunction display for approximately 5 seconds.

i On uphill grades, the cruise control may not be able to maintain the set speed. Once the grade eases, the set speed will be resumed. On downhill grades, the cruise control maintains the set speed by braking with the vehicle’s braking system. In addition, on longer downhill grades the automatic transmission will down- shift automatically.

Distronic*

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 245).

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 responsibili- ty for the vehicle’s speed, distance to the preceding vehicle and, most importantly, brake operation to ensure a safe stopping distance, always rests 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

251

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.

252

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.

Distronic will not react to stationary objects in the roadway (e.g. a stopped vehicle in a traffic jam or a disabled vehicle). Distronic will also not respond to oncoming vehicles.

instrument cluster comes on (컄 page 27).

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

collision. Under no circumstances should the driver await the intermittent warning sound before braking. See the follow- ing warning note. The intermittent warning sound ceases and the distance warning lamp l goes out when the necessary distance to the vehicle ahead is again estab- lished.

254

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 avoid- ed.

Tailgating increases the risk of an accident.

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.

260

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 255). The distance setting switch for the time setting is located on the cruise control le- ver on the left-hand side of the steering column.

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.

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 smaller following distance to the preceding vehicle. 왘 Turn distance setting switch 1 in

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 se- lected by the driver unless a moving obsta- cle proceeding directly ahead of it in the same travel direction is detected (e.g. fol- lowing 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.

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.

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.
