Electronic Stability Control Sportmode
The ESC 7
system is always activated and can-
not be switched off. However, the driver can select
ESC Sport Mode, which offers more
active driving characteristics.
With the ESC Sport Mode sub-function
selected, intervention from ESC is reduced and more lateral movement is permitted, giving thedriver more control of the vehicle than usual. When
ESC Sport Mode is selected, ESC may
seem to be disabled even though it is often assisting the driver.
NOTE
When the ESC Sport Mode function is
selected, the trailer stabilizer (TSA 8
) is
switched off.
ESC Sport Mode also helps provide maximum
traction if the vehicle gets stuck or is driving on a loose surface such as deep snow or loose sand.

For vehicles with only CC
–Change a set speed by pressing the (1)
or
(3) buttons briefly or by pressing and
holding them:
• Press briefly
: Press briefly: each press
changes the speed in +/- 1 mph (+/- 1 km/h) increments.

The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
(1) button on
the steering wheel, the vehicle's speed when the button is pressed will be stored as the set speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
For vehicles with both CC and ACC
–Change a set speed by pressing the (1)
or
(3) buttons briefly or by pressing and
holding them:
• Press briefly
: Press briefly: each press
changes the speed in +/- 5 mph (+/- 5 km/h) increments.

Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver can temporarily disengage the Cruise Con-trol braking function. To disengage CC:
–Press the accelerator pedal about halfway down and then release it.
> Cruise Control will automatically disen- gage the automatic brake function and speed will only be reduced using theengine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive mode 30

Cruise Control Eco Cruise
In the ECO drive mode, cruise control's accelera- tion and deceleration will be smoother than inother drive modes to help provide optimal fuelefficiency and reduced environmental impact.Because of this, the vehicle's actual speed maybe slightly above or below the set speed. For more information, see "ECO drive mode" under "Eco Cruise".
Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control's acceleration and deceleration will be faster andmore immediate than in other drive modes.

Deactivating and putting CruiseControl in standby mode
Cruise Control (CC 31
) can be temporarily put
into standby mode and then reactivated.
Deactivating and putting Cruise Control in standby mode
Note: This illustration is general and details may vary depending on model.
To put Cruise Control in standby mode:
–Press the button on the steering wheel
(2).
> The Cruise Control markings and symbols will change from WHITE to GRAY, indicat- ing that Cruise Control is temporarilydeactivated and the driver needs to con-trol the vehicle's speed.
Standby mode due to action by the driver
Cruise Control will be temporarily deactivated and put in standby mode if:
• the brakes are applied
• the gear selector is moved to
N
• the vehicle is driven faster than the setspeed for more than 1 minute
The driver must then control the vehicle's speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Cruise Control will be temporarily deactivated and put in standby mode if:
• the wheels lose traction
• the engine speed (rpm) is too low/high
• the temperature in the brake systembecomes too high
• the vehicle's speed goes below 30 km/h(20 mph).
The driver must then control the vehicle's speed.

To temporarily deactivate Adaptive Cruise Control and put it in standby mode:
–Press the button on the steering wheel
(2). > The
symbol in the instrument panel
changes color from WHITE to GRAY and the set speed in the center of the speed-ometer will change from BEIGE to GRAY.
WARNING
• If Adaptive Cruise Control is in standby mode, the driver must intervene and regu-late both speed and distance to the vehicleahead.
• If the vehicle comes too close to a vehicleahead when Adaptive Cruise Control is instandby mode, the driver is instead warnedof the short distance by the Distance Alertfunction.
Standby mode due to action by the driver
Adaptive Cruise Control will be temporarily deac- tivated and put in standby mode if:
• the brakes are applied.
• the gear selector is moved to
N
• the vehicle is driven faster than the setspeed for more than 1 minute Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Adaptive Cruise Control is dependent on other systems, such as Electronic Stability Control (ESC 50
). If any of these other systems stops
working, Adaptive Cruise Control will automati- cally switch off.
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a messageon the instrument panel. • The driver must then regulate vehicle speed, apply the brakes if necessary, andmaintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standbymode if: • your vehicle's speed goes below 5 km/h(3 mph) and ACC cannot determine if thevehicle ahead is stationary or if it is anotherobject, e.g. a speed bump.
• your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatACC no longer has a vehicle to follow. •
the driver opens the door.
• the driver unbuckles the seat belt.
• the engine speed (rpm) is too low/high.
• one or more of the wheels lose traction.
• the brake temperature is high.
• the parking brake is applied.
• the camera/radar sensor is covered by snowor heavy rain (the camera lens/radar wavesare blocked)
