System limits
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Deceleration
The system does not decelerate in the following
situations:▷For pedestrians, cyclists or similarly slow-
moving road users.▷For red traffic lights.▷For cross traffic.▷For oncoming traffic.▷Unlit vehicles or vehicles with nonworking
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.
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, for ex‐
ample, when rapidly approaching a truck.
When a vehicle driving ahead of you is reliably
detected, the system requests that the driver
intervene by braking and carrying out evasive
maneuvers, if needed.

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.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system decelerates
you may compensate it by briefly accelerating.
After releasing the gas pedal the system is reac‐
tivated and controls speed independently.
Weather
In the event of unfavorable weather and light conditions, e. g. if there is rain, snowfall, slush,
fog or glare, this may result in poorer recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected.
Drive attentively, and react to the current traffic
situation. If necessary, intervene actively, for
example by braking, steering or evading.
Engine power
The desired speed may not be maintained on
uphill grades if engine power is insufficient.
Malfunction A Check Control message is displayed if the sys‐
tem fails or was automatically deactivated.
The system may not be fully functional in the
following situations:▷When an object was not correctly detected.▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the field of view of the camera or the
windshield are dirty or covered.▷When driving toward bright lights.▷Up to 20 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.
Cruise control
The concept
Using this system, a desired speed can be ad‐
justed using the buttons on the steering wheel.
The system maintains the desired speed. The
system accelerates and brakes automatically as
needed.
General information
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
Depending on the driving settings, the features
of the cruise control can change in certain
areas.

Things to remember when drivingVehicle features and op‐tions
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 sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features 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.
During break-in, do not use the Launch Control,
refer to page 78.
Information WARNING
Due to new parts and components, safety
and driver assistance systems can react with a
delay. There is risk of an accident. After instal‐
ling new parts or with a new vehicle, drive con‐
servatively and intervene early if necessary. Ob‐
serve the break-in procedures of the respective
parts and components. ◀
Engine, transmission, and axle drive
Up to 1,200 miles/2,000 km Do not exceed the maximum engine and road
speed:▷For gasoline engine 4,500 rpm and
100 mph/160 km/h.
Avoid full load or kickdown under all circum‐
stances.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
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 brake pads.
Drive moderately during this break-in period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
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.

General driving notes
Closing the tailgate WARNING
An open tailgate protrudes from the vehi‐
cle and can endanger occupants and other traf‐
fic participants or damage the vehicle in the
event of an accident, braking or evasive ma‐
neuvers. In addition, exhaust fumes may enter
the vehicle interior. There is a risk of injury or
risk of property damage. Do not drive with the
tailgate open. ◀
If driving with the tailgate open cannot be
avoided:▷If the convertible top is closed, close all
windows and the sliding sun roof.▷Greatly increase the air flow from the vents.▷Drive moderately.
Hot exhaust system
WARNING
During driving operation, high tempera‐
tures can occur underneath the vehicle body,
e.g., caused by the exhaust gas system. If com‐
bustible materials, such as leaves or grass,
come in contact with hot parts of the exhaust
gas system, these materials can ignite. There is
a risk of injury or risk of property damage.
Do not remove the heat shields installed and
never apply undercoating to them. Make sure
that no combustible materials can come in con‐
tact with hot vehicle parts in driving operation,
idle or during parking. Do not touch the hot ex‐
haust system. ◀
Mobile communication devices in the vehicle
WARNING
Vehicle electronics and mobile phones
can influence one another. There is radiation
due to the transmission operations of mobile
phones. There is a risk of injury or risk of prop‐
erty damage. If possible, in the vehicle's interior
use only mobile phones with direct connections
to an exterior antenna in order to exclude mu‐
tual disturbance and deflect the radiation from
the vehicle's interior. ◀
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 ATTENTION
When driving too quickly through too
deep water, water can enter into the engine compartment, the electrical system or the
transmission. There is a risk of damage to prop‐
erty. When driving through water, do not ex‐
ceed the maximum indicated water level and
the maximum speed for driving through wa‐
ter. ◀
When driving through water, observe the fol‐
lowing:▷Drive through calm water only.▷Drive through water only if it is not deeper
than maximum 9.8 inches/25 cm.▷Drive through water no faster than walking
speed, up to 3 mph/5 km/h.
Braking safely
Your vehicle is equipped with ABS as a standard
feature.
Perform an emergency stop in situations that require such.
Steering is still responsive. You can still avoid
any obstacles with a minimum of steering ef‐
fort.
