Important safety notes

WARNING
The brake pedal moves when cruise control brakes the vehicle. A foot in the area under the brake pedal could become trapped. The movement of the pedal, and therefore the vehicle's ability to brake, may be restricted by objects in the area under the brake. There is a risk of an accident and injury.

Do not place your foot under the brake pedal.

Keep the area under the brake pedal free from obstructions.

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

Cruise control cannot take account of road, weather and traffic conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Adjust your driving style to the traffic conditions.

Only engage cruise control when the current road, weather and traffic conditions permit it to be done safely. Drive carefully and maintain a suitable distance to the vehicle in front.

Do not use cruise control: in traffic conditions that do not allow you to drive at a constant speed, e.g. heavy traffic, on winding roads or off-road on slippery road surfaces. Braking or accelerating could cause the drive wheels to lose traction and the vehicle could then skid
when there is poor visibility, e.g. due to fog, heavy rain or snow

General notes

Cruise control maintains a constant road speed for you. On long and steep downhill gradients, especially if the vehicle is laden, 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.

Use cruise control only if road and traffic conditions make it appropriate to maintain a steady speed for a prolonged period. You can store any road speed above 20 mph (30 km/h).

Cruise control should not be activated during off-road driving.

Cruise control lever

1 To activate or increase speed


1 To activate or increase speed 2 LIM indicator lamp> 3 To activate at the current speed/last stored speed> 4 To activate or reduce speed> 5 To switch between cruise control and variable SPEEDTRONIC> 6 To deactivate cruise control

You can operate cruise control and variable SPEEDTRONIC with the cruise control lever.

When you activate cruise control, the stored speed is shown in the multifunction display for five seconds.

The full range of cruise control functions will become available again once you confirm the DEF display message: X Briefly press the ,,
or,
button on the multifunction or
steering button on the multifunction
steering wheel.

or
Briefly press the reset button on the instrument cluster.

The LIM indicator lamp on the cruise control lever indicates which system you have selected:
LIM indicator lamp off:

cruise control is selected.

LIM indicator lamp on:

variable SPEEDTRONIC is selected.

Activation conditions

To activate cruise control, all of the following activation conditions must be fulfilled: the parking brake must be released.

you are driving faster than 20 mph (30 km/h).

ESP must be active, but not intervening.

the transmission must be in position D.

Selecting cruise control

1 To activate or increase speed


1 To activate or increase speed 2 LIM indicator lamp> 3 To activate at the current speed/last stored speed> 4 To activate or reduce speed> 5 To switch between cruise control and variable SPEEDTRONIC> 6 To deactivate cruise control

Check whether LIM indicator lamp 2 is off.

If it is off, cruise control is already selected.

If it is not, press the cruise control lever in the direction of arrow 5.

LIM indicator lamp 2 in the cruise control lever goes out. Cruise control is selected.

Calling up the last speed stored

Storing and maintaining

1 To activate or increase speed


1 To activate or increase speed 2 LIM indicator lamp> 3 To activate at the current speed/last stored speed> 4 To activate or reduce speed> 5 To switch between cruise control and variable SPEEDTRONIC> 6 To deactivate cruise control

You can store the current speed if you are driving faster than 20 mph (30 km/h).

Accelerate the vehicle to the desired speed.

Briefly press the cruise control lever up  or down 4.

Remove your foot from the accelerator pedal.

Cruise control is activated. The vehicle automatically maintains the stored speed.

Cruise control may be unable to maintain the stored speed on uphill and downhill gradients. The stored speed is resumed when the gradient levels out. Cruise control maintains the stored speed on downhill gradients by automatically applying the brakes.

Calling up the last speed stored

WARNING
If you call up the stored speed and it is lower than the current speed, the vehicle decelerates. If you do not know the stored speed, the vehicle could decelerate 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.

1 To activate or increase speed


1 To activate or increase speed 2 LIM indicator lamp> 3 To activate at the current speed/last stored speed> 4 To activate or reduce speed> 5 To switch between cruise control and variable SPEEDTRONIC> 6 To deactivate cruise control

Briefly pull the cruise control lever towards you 3.

Remove your foot from the accelerator pedal.

Cruise control is activated and adjusts the vehicle's speed to the last speed stored.

If no speed is stored, cruise control stores the current speed and maintains it.

Setting a speed

Adjusting

1 To activate or increase speed


1 To activate or increase speed 2 LIM indicator lamp> 3 To activate at the current speed/last stored speed> 4 To activate or reduce speed> 5 To switch between cruise control and variable SPEEDTRONIC> 6 To deactivate cruise control

Keep in mind that it may take a brief moment until the vehicle accelerates or decelerates to the set speed.

To increase the speed: press the cruise control lever up 1.

To decrease the speed: press the cruise control lever down 4.

Keep the cruise control lever pressed until the desired speed is reached.

Release the cruise control lever.

The new speed is stored.

Making adjustments in 1 mph increments (1 km/h increments in Canada)

1 To activate or increase speed


1 To activate or increase speed 2 LIM indicator lamp> 3 To activate at the current speed/last stored speed> 4 To activate or reduce speed> 5 To switch between cruise control and variable SPEEDTRONIC> 6 To deactivate cruise control

Briefly press the cruise control lever up 1 for a higher speed or down 4 for a lower speed.

The last speed stored is increased or reduced.

Adjusting in 5 mph increments (10 km/h increments):

1 To activate or increase speed


1 To activate or increase speed 2 LIM indicator lamp> 3 To activate at the current speed/last stored speed> 4 To activate or reduce speed> 5 To switch between cruise control and variable SPEEDTRONIC> 6 To deactivate cruise control

Briefly press the cruise control lever up 1 or down 4 to beyond the pressure point.

The last speed stored is increased or reduced.

Cruise control is not deactivated if you depress the accelerator pedal. For example, if you accelerate briefly to overtake, cruise control adjusts the vehicle's speed to the last speed stored after you have finished overtaking.

Deactivating cruise control

1 To activate or increase speed


1 To activate or increase speed 2 LIM indicator lamp> 3 To activate at the current speed/last stored speed> 4 To activate or reduce speed> 5 To switch between cruise control and variable SPEEDTRONIC> 6 To deactivate cruise control

There are several ways to deactivate cruise control: X Briefly press the cruise control lever forwards 6.

Brake.

or
Briefly press the cruise control lever in the direction of arrow 5.

Variable SPEEDTRONIC is selected. LIM indicator lamp 2 in the cruise control lever lights up.

Cruise control is automatically deactivated if: Ryou apply the parking brake.

Ryou are driving at less than 20 mph (30 km/h).

RESP intervenes or you deactivate ESP.

Ryou shift the transmission to position N while driving.

The last speed stored is cleared when you switch off the engine.
