Cruise controlThe concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀

Maintaining, storing, and changing the
speed
Hints Adjusting the desired speed
Modify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Maintaining/storing the speed Press button.
Or:
Press the rocker reel while the system is inter‐
rupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
This is displayed, refer to page 143, in the
speedometer and briefly in the instrument
cluster.
When cruise control is maintained or stored,
DSC Dynamic Stability Control will be turned
on if needed.
Changing the speed
Press the rocker reel up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed when the
road is clear.
▷Each time the rocker reel is pressed to the
point of resistance, the desired speed in‐creases or decreases by approx. 1 mph/
km/▷Each time the rocker reel is pressed past
the point of resistance, the desired speed
increases or decreases by a maximum of
5 mph/10 km/h.
The maximum speed that can be set de‐
pends on the vehicle.▷Pressing the rocker reel to the resistance
point and holding it accelerates or deceler‐
ates the vehicle without requiring pressure
on the accelerator pedal.
After the rocker reel is released, the vehicle
maintains its final speed. Pressing the reel
beyond the resistance point causes the ve‐
hicle to accelerate more rapidly.
Resuming the desired speed
Press button.
The stored speed is reached and maintained. Displays in the instrument cluster
Indicator lamp Depending on how the vehicle is equip‐
ped, the indicator lamp in the instru‐
ment cluster indicates whether the sys‐
tem is switched on.

Coasting
The concept
The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐
sion when selector lever position D is set. The
vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coast‐
ing.
As soon as you step on the brake or accelera‐
tor pedal, the engine is automatically coupled
again.
Hints
Coasting is a component of the ECO PRO, re‐
fer to page 178, driving mode.
Coasting is automatically activated when ECO
PRO mode is called via the Driving Dynamics
Control.
The function is available in a certain speed
range.
A proactively driving style helps the driver to
use the function as often as possible and sup‐
ports the fuel-conserving effect of coasting.
Safety mode
The function is not available under one of the
following conditions.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In ECO PRO mode, this function is available in
a speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h, if
the following conditions are met:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.
The driving status Coast can be influenced
with the shift paddles.
Display Display in the instrument cluster The mark in the bar display be‐
low the tachometer is backlit in
blue and is located at the zero
point. The tachometer approxi‐
mately indicates idle speed.
