WARNING •
The cruise control function is supplemen-
tary driver support intended to facilitate
driving and help make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
• The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).
• Cruise control is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

288Managing Cruise Control speed
Cruise Control (CC 29
) can be set to various
speeds.
Setting/changing set speed Note: This illustration is general and details may vary
depending on model.
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.
• Press and hold: Release the button when
the set speed indicator (4) has moved to
the desired speed. •
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, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
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.
• Press and hold: Release the button when
the set speed indicator (4) has moved to
the desired speed.
• 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, will not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applying
the brakes. On downgrades, it can sometimes be
desirable to roll a bit faster and let speed be
reduced instead by engine braking alone. The
driver 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 the
engine braking function.
How drive mode affects cruise controlThe way the cruise control maintains the vehicle's
speed can vary depending on the selected drive
mode 30

become aware if the time interval to the vehicle
in front is too short.
However, the vehicle must be equipped with a
head-up display in order to display the Distance
Alert, which will then be indicated by a symbol
on the windshield as long as the time interval to
the vehicle ahead is shorter than the set time
interval.
Distance Alert is active at speeds above 30 km/h
(20 mph) and only reacts for vehicles ahead mov-
ing in the same direction as your vehicle. No dis-
tance information is provided for oncoming, slow-

When the vehicle is approaching an off-ramp or a
fork in the road, the driver should steer toward
the desired lane to indicate to Pilot Assist the
desired direction of travel.
Pilot Assist strives to keep the vehicle
in the center of the lane
When Pilot Assist provides steering assistance, it
strives to position the vehicle in the center of the
lane between the lane markings. For the smooth-
est driving experience possible, the driver should
permit the vehicle to find the optimal positioning.
The driver should check that the vehicle is posi-
tioned safely in the lane and can always adjust
the vehicle's position by applying more force to
the steering wheel.
If Pilot Assist does not position the vehicle appro-
priately in the lane, the driver should turn off Pilot
Assist or switch to Adaptive Cruise Control.

Automatic transmission
Pilot Assist can follow another vehicle at speeds
from a standstill up to 200 km/h (125 mph).
The lowest speed that can be set for Pilot Assist
is 30 km/h (20 mph). When following another
vehicle, ACC can monitor that vehicle's speed
and slow your own vehicle down to a standstill,
but it is not possible to set speeds lower than
30 km/h (20 mph). The highest possible speed that can be set is
200 km/h (125 mph).

Pilot Assist (p. 311) Setting a time interval for Pilot
Assist
Pilot Assist
can be set to different time intervals.
Different time intervals to the
vehicle ahead can be selected
and are shown in the instru-
ment panel as 1–5 horizontal
bars. The more bars, the longer
the time interval. One bar rep-
resents an interval of
approx. 1 second to the vehicle ahead. 5 bars
represents approx. 3 seconds.
NOTE When the symbol in the instrument panel
shows a vehicle and a steering wheel, Pilot
Assist follows a vehicle ahead at a preset
time interval.
When only a steering wheel is shown, there is
no vehicle ahead within a reasonable dis-
tance.

view. However, each time the
engine is started, the previous side view will be
replaced by the 360° view and a previously dis-
played zoomed-in rear view will be replaced by
the regular rear view.
Automatically deactivating the cameraFront view switches off when the vehicle's speed
reaches 25 km/h (16 mph) to help avoid dis-
tracting the driver. It will be automatically reactiva-
ted if the vehicle's speed falls below 22 km/h
(14 mph) within 1 minute as long as the vehicle's
speed has not exceeded 50 km/h (31 mph). Other camera views switch off at 15 km/h
(9 mph) and are not reactivated.

• Loading recommendations (p. 586) Low Speed Control
The low-speed function, Low Speed Control
(LSC), facilitates and improves control and trac-
tion on rough roads and slippery surfaces, e.g.
when towing a trailer on grass or up boat ramps.
The function is included in the Off Road drive
mode.
Low Speed Control is designed for driving on
rough roads and when towing trailers at low
speeds, up to approximately 40 km/h (25 mph).
When driving at low speeds, LSC prioritizes low
gears and all-wheel drive to help avoid wheel spin
and improve traction on all wheels. The accelera-
tor pedal will be less responsive to improve trac-
tion and speed control at low speeds.
The function is activated together with Hill
Descent Control (HDC), which makes it possible
to control speed going down steep hills using the
accelerator pedal and reduces the need to use
the brake pedal. The system makes it possible to
maintain a low and uniform speed when driving
down steep hills.

Factors the driver can control
The driver should be aware that the following fac-
tors help conserve energy and improve driving
range: • charging the battery regularly
• preconditioning
• Pure drive mode
• climate control settings
• speed and acceleration
• the
Hold function
• tires and tire pressure.
The following table shows the approximate rela-
tionship between constant speed and driving
range. Driving at a lower constant speed helps
increase the electric motor's driving range. Constant speed

The figures shown in the tables pertain to
a new vehicle.
• None of the figures are absolute and are

In certain situations, it can be useful to control
the hybrid battery's charge level while driving.
This is possible with the Hold and Charge func-
tions, which are available in all drive modes.
Function buttons for Hold and ChargeThe functions can be activated in the center dis-
play's Function view.
Hold
Battery level sustained for
later use.
This function retains the charge
in the hybrid battery for the
electric motor and saves availa-
ble electrical current for use at
a later time, such as when driving in an urban
area or residential neighborhood. Hold is availa-
ble regardless of the hybrid battery's charge level.
The vehicle will function as in normal hybrid driv-
ing with a discharged battery - in addition to
reusing energy from e.g. regenerative braking, the
combustion engine will be used more frequently
to maintain the charge in the battery.
