Important safety notes

WARNING
DISTRONIC PLUS does not react to: people or animals stationary obstacles on the road, e.g.

stopped or parked vehicles oncoming and crossing traffic

As a result, DISTRONIC PLUS may neither give warnings nor intervene in such situations.

There is a risk of an accident.

Always pay careful attention to the traffic situation and be ready to brake.

WARNING
DISTRONIC PLUS cannot always clearly identify other road users and complex traffic situations.

In such cases, DISTRONIC PLUS may: give an unnecessary warning and then brake the vehicle
neither give a warning nor intervene accelerate unexpectedly

There is a risk of an accident.

Continue to drive carefully and be ready to brake, in particular when warned to do so by DISTRONIC PLUS.

WARNING
DISTRONIC PLUS brakes your vehicle with up to 40% of the maximum braking force. If this braking force is insufficient, DISTRONIC PLUS warns you visually and audibly. There is a risk of an accident.

In such cases, apply the brakes yourself and try to take evasive action.

WARNING
If you call up the stored speed and it differs from the current speed, the vehicle accelerates or decelerates. If you do not know the stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an accident.

Pay attention to the road and traffic conditions before calling up the stored speed.

If you do not know the stored speed, store the desired speed again.

If you fail to adapt your driving style, DISTRONIC PLUS can neither reduce the risk of accident nor override the laws of physics.

DISTRONIC PLUS cannot take account of road, weather and traffic conditions.

DISTRONIC PLUS is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Only engage DISTRONIC PLUS when the current road, weather and traffic conditions permit it to be done safely, and adapt your driving style accordingly. Drive carefully and maintain a suitable distance to the vehicle in front.

If DISTRONIC PLUS detects a risk of collision but cannot sufficiently decelerate the vehicle in order to maintain the set distance, you will be warned visually and acoustically.

DISTRONIC PLUS cannot prevent a collision without your intervention. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster. Brake immediately in order to increase the distance from the vehicle in front, or take evasive action, provided it is safe to do so.

DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving on a different line. Therefore, always pay attention to traffic conditions even when DISTRONIC PLUS is activated.

Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

In particular, the detection of obstacles can be impaired if there is: the sensor is dirty or covered snow or heavy rain interference by other radar sources there is the possibility of strong radar reflections, for example, in parking garages.

If DISTRONIC PLUS is activated, the vehicle brakes automatically in certain situations.

This can happen unexpectedly, especially when towing or in a car wash. There is a risk of an accident. In these or similar situations, deactivate DISTRONIC PLUS.

If you want DISTRONIC PLUS to assist you, the following activation conditions must be fulfilled  and the radar sensor system must be operational.

General notes

DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front.

DISTRONIC PLUS brakes automatically so that the set speed is not exceeded.

On long and steep downhill gradients, especially if the vehicle is laden or towing a trailer, you must select shift range 1, 2 or 3 in good time. By doing so, you will make use of the braking effect of the engine, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.

If DISTRONIC PLUS detects a slower-moving vehicle in front, your vehicle is braked in order to maintain the preset distance to the vehicle in front.

If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control in the speed range between 20 mph (Canada: 30 km/h) and120 mph (Canada: 200 km/h). If a vehicle is driving in front of you, it operates in the speed range between 0 mph (0 km/h) and 120 mph (Canada: 200 km/h).

Do not use DISTRONIC PLUS while driving on roads with steep gradients.

As DISTRONIC PLUS transmits radar waves, it can resemble the radar detectors of the responsible authorities. You can refer to the relevant chapter in the Operator's Manual if questions are asked about this.

  the DISTRONIC PLUS function must be selected .

the transfer case must be in the HIGH RANGE transmission position.

  the vehicle must not be on an uphill or downhill gradient of more than 22-25%.

  the radar sensor must be free from dirt .

Activating while driving

When driving at speeds below 20 mph


When driving at speeds below 20 mph (30 km/h) you can activate DISTRONIC PLUS if the vehicle in front has been detected and is shown in the multifunction display. If the vehicle in front is no longer detected and displayed, DISTRONIC PLUS switches off and a tone sounds.

Briefly pull the cruise control lever towards you 4, or press it up 1 or down 5.

DISTRONIC PLUS is selected.

Press the cruise control lever up 1 or down 5 repeatedly until the desired speed is set.

Remove your foot from the accelerator pedal.

Your vehicle adapts its speed to that of the vehicle in front, but only up to the desired stored speed.

If you do not fully release the accelerator pedal, the DISTRONIC PLUS Passive message appears in the multifunction display. The set distance to a slowermoving vehicle in front will then not be maintained. You will be driving at the speed you determine by the position of the accelerator pedal.

Switching on while stationary

This function may be useful if you want to keep up with the traffic flow, e.g. at the end of a tailback.

You can only activate DISTRONIC PLUS if: Rthe vehicle in front and Ryour vehicle are stationary X Briefly pull the cruise control lever towards you 4, or press it up 1 or down 5.

DISTRONIC PLUS is selected.

DISTRONIC PLUS can be activated at a standstill at under 20 mph (30 km/h) only if a vehicle in front has been detected.

Therefore, the DISTRONIC PLUS distance display in the instrument cluster should be activated .

Keep the cruise control lever pressed up 1 or down 5  until the desired speed is set.

You can use the cruise control lever to set the stored speed and the control on the cruise control lever to set the specified minimum distance .

Activating at the current speed/last stored speed

WARNING
If you call up the stored speed and it differs from the current speed, the vehicle accelerates or decelerates. If you do not know the stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an accident.

Pay attention to the road and traffic conditions before calling up the stored speed.

If you do not know the stored speed, store the desired speed again.

Briefly pull the cruise control lever towards you 4.

Remove your foot from the accelerator pedal.

DISTRONIC PLUS is activated. The first time it is activated, the current speed is stored. Otherwise, it sets the vehicle cruise speed to the previously stored value.

Driving with DISTRONIC PLUS

Pulling away and driving

► If the vehicle in front pulls away: remove


If the vehicle in front pulls away:

remove your foot from the brake pedal.

Briefly pull the cruise control lever towards you 4, or press it up 1 or down 5.

or
Accelerate briefly.

Your vehicle pulls away and adapts its speed to that of the vehicle in front.

If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control.

If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle. In this way, the distance you have selected is maintained.

If DISTRONIC PLUS detects that the vehicle in front is driving faster, it accelerates your vehicle, but only up to the speed you have stored.

If you depress the brake, DISTRONIC PLUS is deactivated unless your vehicle is stationary.

Changing lanes

If you change to the passing lane, DISTRONIC PLUS supports you when:
you are driving faster than 40 mph (60 km/h).

DISTRONIC PLUS is maintaining the distance to a vehicle in front.

you switch on the appropriate turn signal.

DISTRONIC PLUS does not detect a danger of collision.

If these conditions are fulfilled, your vehicle is accelerated. Acceleration will be interrupted if changing lanes takes too long or if the distance between your vehicle and the vehicle in front becomes too small.

i When changing lanes, DISTRONIC PLUS monitors the left lane on left-hand drive vehicles and the right lane on right-hand drive vehicles.

Stopping

WARNING
When leaving the vehicle, even if it is braked only by DISTRONIC PLUS, it could roll away if: there is a malfunction in the system or in the voltage supply.

DISTRONIC PLUS has been deactivated with the cruise control lever, e.g. by a vehicle occupant or from outside the vehicle.

the electrical system in the engine compartment, the battery or the fuses have been tampered with.

the battery is disconnected.

the accelerator pedal has been depressed, e.g. by a vehicle occupant.

There is a risk of an accident.

If you wish to exit the vehicle, always turn off DISTRONIC PLUS and secure the vehicle against rolling away.

If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary.

Once your vehicle is stationary, it remains stationary and you do not need to depress the brake.

Depending on the specified minimum distance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in front. The specified minimum distance is set using the control on the cruise control lever.

On steep uphill or downhill inclines or if there is a malfunction, the transmission may also automatically be shifted into position P.

Every time the cruise control lever is pressed up 1 or down 2, the last speed stored is increased or reduced.

 DISTRONIC PLUS is not deactivated if you depress the accelerator pedal. If you accelerate to overtake, DISTRONIC PLUS adjusts the vehicle's speed to the last speed stored after you have finished overtaking.

Setting the specified minimum distance

You can set the specified minimum distance


You can set the specified minimum distance for DISTRONIC PLUS by varying the time span between one and two seconds. With this function, you can set the minimum distance that DISTRONIC PLUS keeps to the vehicle in front, dependent on vehicle speed. You can see this distance in the multifunction display .

To increase: turn control 3 in direction 2.

DISTRONIC PLUS then maintains a greater distance between your vehicle and the vehicle in front.

To decrease: turn control 3 in direction 1.

DISTRONIC PLUS then maintains a shorter distance between your vehicle and the vehicle in front.

Make sure that you maintain the minimum distance to the vehicle in front as required by law. Adjust the distance to the vehicle in front if necessary.
