System limits
Speed range The system is best used on well-constructedroads.
The desired speed can be set between
20 mph/30 km/h and 85 mph/140 km/h.
The system can also be activated when sta‐
tionary.
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection lidacity of the system and the
automatic braking lidacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Limited detection potential
Because of the limited possible detec‐
tion, you should be alert at all times so that you
can intervene if needed; otherwise, there is the
risk of an accident.◀
Deceleration
The system does not decelerate for:
▷Pedestrians, cyclists or similar slow road
users.▷Red traffic lights.▷Cross traffic.▷Oncoming traffic.▷Unlit vehicles or vehicles with defective
lighting at night.Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if needed. You must react yourself; other‐
wise, there is the risk of an accident.◀
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.

▷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‐

PDC Park Distance Control The conceptPDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is availa‐
ble - then the object is reported through:▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on the ob‐
stacle and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and the two rear cor‐
ner sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
To ensure full functionality:
▷Do not cover sensors, e.g., with stickers,
bicycle racks and the like.▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.
Hints
Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Seite 115Driving comfortControls117
Volume
The volume of the PDC signal tone can be ad‐
justed similar to the sound and volume set‐
tings of the radio.
Settings are stored for the profile currently in
use.
Visual warning
The approach of the vehicle to an object can
be shown on the Control Display. Objects that
are farther away are already displayed on the
Control Display before a signal sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.
The range of the sensors is represented in the
colors green, yellow and red.
When the image of the rearview camera is dis‐
played, the reel can be made to PDC:
"Rear view camera"
System limits
Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:
▷For small children and animals.▷For persons with certain clothing, e.g.
coats.▷With external interference of the ultra‐
sound, e.g. from passing vehicles or loud
machines.▷When sensors are dirty, iced over, dam‐
aged or out of position.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.▷With tow bars and trailer couplings of other
vehicles.▷With thin or wedge-shaped objects.▷With moving objects.▷With elevated, protruding objects such as
ledges or cargo.▷With objects with corners and sharp edges.▷With objects with a fine surface structure
such as fences.▷For objects with porous surfaces.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before
or after a continuous tone sounds.
False warnings
PDC may issue a warning under the following conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered
with ice.▷When sensors are covered in snow.▷On rough road surfaces.▷On uneven surfaces, such as speed
bumps.▷In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.▷Through heavy pollution.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.

Things to remember when drivingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Breaking-in period
General information Moving parts need time to adjust to one an‐
other (break-in time).
The following instructions will help accomplish
a long vehicle life and good efficiency.
Range Extender The full performance of the Range Extender is
available after a brief operating period and is
only minimally restricted during the run-in
phase.
Control of the Range Extender during and after
the run-in phase, as well as the activation of
the full performance, are preset depending on
the system and take place automatically.
Tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimal per‐
formance between brake discs and brakepads. Drive moderately during this break-in pe‐
riod.
Following part replacement
The same break-in procedures should be ob‐
served if any of the components above-men‐
tioned have to be renewed in the course of the
vehicle's operating life.
Using eDRIVE efficiently The concept
eDRIVE operates automatically. Proactive driv‐
ing utilizes energy consumption and energy re‐
covery optimally. Energy recovery is used to
charge the high-voltage battery. It is important
for the supply of electrical components and
thus a prerequisite for an extensive range. En‐
ergy consumption and recovery depend very
much, among other things, on your driving
style.
Optimizing driving style
Performance display The driving style can be optimized using the
performance display.
The energy recovery occurs during coasting
and braking and is displayed in the perform‐
ance display by the accelerator pedal indicator.
Seite 142Driving tipsThings to remember when driving144
The accelerator pedal pointer is within the
CHARGE range.
Efficient energy recovery:▷The accelerator pedal moves to the left
within the blue range of the CHARGE dis‐
play, arrow 1.▷The energy use while driving can be opti‐
mized by efficient acceleration.
Efficient acceleration:
▷The accelerator pedal moves to the right
within the blue range of the ePOWER dis‐
play, arrow 2.▷Use deceleration during coasting as often
as possible for energy recovery.
Brake according to traffic and circum‐
stances
Brake in accordance with the traffic conditions,
or there is the risk of accident.◀
Discharge of the high-voltage battery
Longer idle periods can reduce the charge
state of the high-voltage battery.
Do not allow the vehicle to sit idle for ex‐
tended periods with a low charging state
Before storing the vehicle for an extended pe‐
riod, check the battery charge indicator to en‐
sure that the high-voltage battery is fully
charged. During the idle period, connect the
vehicle to a charging station at a suitable
charging location. If necessary, the high-volt‐
age battery will be charged automatically.
Make sure that the charging process takes
place. Regularly check the charging state.
Don't allow battery charge status to drop too
low - it will damage the battery.◀
General driving notes
Closing the tailgate Drive with the tailgate closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking and
evasive maneuvers, passengers and other traf‐
fic may be injured, and the vehicle may be
damaged. Moreover, exhaust gases can get
into the vehicle interior and the lights in the
tailgate cannot be recognized.◀
If driving with the tailgate open cannot be
avoided:▷Close all windows and the glass sunroof.▷Greatly increase the air flow from the vents.▷Drive moderately.
Hot exhaust system
Hot exhaust system
High temperatures are generated in the
exhaust system.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that flammable materials, e. g. hay, leaves,
grass, etc. do not come in contact with the hot
exhaust system while driving, while in idle po‐
sition mode, or when parked. Such contact
could lead to a fire, resulting in an increased
risk of serious personal injury as well as prop‐
erty damage.
Do not touch hot exhaust pipes; otherwise,
there is a danger of getting burned.◀
Mobile communication devices in the
vehicle
Mobile communication devices in the ve‐
hicle
It is not recommended to use mobile phones,
such as mobile phones, in the vehicle interior
without a direct connection to an external aer‐
ial. Otherwise, the vehicle's electronics and
mobile communication devices can interfere
Seite 143Things to remember when drivingDriving tips145
with each other. In addition, there is no assur‐
ance that the radiation generated during trans‐
mission will be conducted away from the vehi‐
cle interior.◀
Hydroplaning Hydroplaning
When driving on wet or slushy roads, re‐
duce your speed to prevent hydroplaning.◀
On wet or slushy roads, a wedge of water can
form between the tires and road surface.
This phenomenon is referred to as hydroplan‐
ing. It is characterized by a partial or complete
loss of contact between the tires and the road
surface, ultimately undermining your ability to
steer and brake the vehicle.
Driving through water Observe water level and speed
Do not exceed the maximum water level
and maximum speed; otherwise, the vehicle's
engine, the electrical systems and the trans‐
mission may be damaged.◀
Drive though calm water only and only if it is
not deeper than 9.8 inches/25 cm and at this
height, no faster than walking speed, up to 3 mph/5 km/h.
Braking safely
Your vehicle is equipped with ABS as a stand‐
ard feature.
Applying the brakes fully is the most effective
way of braking in situations needed.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
Pulsation of the brake pedal and sounds from
the hydraulic circuits indicate that ABS is in its
active mode.
In certain braking situations, the perforated
brake discs can cause functional problems.However, this has no effect on the perform‐
ance and operational reliability of the brake.
Objects in the range of movement of the pedals and in the footwell
Do not allow objects in the interior
around pedals and foot space
Keep floor mats, carpets, and any other ob‐
jects out of the pedal area and do not stow
them in the footwell; otherwise, the function of
the pedals could be impeded while driving.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Hills Avoid stressing the brakes
Avoid placing excessive stress on the
brake system. Light but consistent brake pres‐
sure can lead to high temperatures, brakes
wearing out and possibly even brake failure.◀
Do not drive in neutral
Do not drive in neutral or with drive readi‐
ness switched off, as doing so disables engine
braking. In addition, steering and brake assist
are unavailable with the engine stopped.◀
On downhill sections, use energy recovery if
possible to decelerate the vehicle.
Brake disc corrosion
Brake disc corrosion and contamination of the
brake pads are favored by:▷Low mileage.▷Extended periods when the vehicle is not
used at all.▷Infrequent use of the brakes.Seite 144Driving tipsThings to remember when driving146
