For information on the current map version

and map updates, see Map update in the Nav-

igation system chapter.

Vehicle features and options

This chapter describes all standard, country-

specific, and optional equipment offered with

the series. It also describes features and func-

tions that are not necessarily available in the

vehicle, e.g., due to the selected options or

country versions. This also applies to safety

functions and systems. When using these

functions and systems, the applicable laws

and regulations must be observed.

Without a navigation system, the system is

subject to limitations imposed by technology.

Traffic signs with speed limitations are de-

tected and displayed only. Speed limits due to

entering towns/cities, highway signs, etc., are

not displayed. Speed limits with extra traffic

signs are always displayed.

Additional information:

Owner's Manual for Navigation, Entertain-

ment, and Communication, refer to page 6.

Speed Limit Info

Warning

Principle

The system cannot serve as a substitute for

the driver’s personal judgment in assessing

the traffic situation. Based on the limits of

the system, it cannot independently react to

all traffic situations. There is a risk of acci-

dent, injury, or property damage. Adjust driv-

ing style to traffic conditions. Watch the sur-

rounding traffic situation closely, be ready to

take over steering and braking at any time,

and actively intervene where appropriate.

Speed Limit Info shows the currently valid

speed limit in the instrument cluster and, if

necessary, the Head-up display.

General information

The camera in the area of the interior mirror

detects traffic signs at the edge of the road as

well as overhead sign posts.

Traffic signs with extra icons are considered

and compared with the vehicle's onboard data.

The traffic sign will then be either displayed

or ignored depending on the situation in the

instrument cluster and the Head-up display.

Overview

Sensors

With the navigation system, the system takes

into account the information stored in the nav-

igation system and also displays speed limits

present on routes without signs.

The system is controlled by cameras behind

the windshield.

Additional information:

For Speed Limit Info to function correctly, cur-

rent map data for the country in which the ve-

hicle is operated must be downloaded.

Sensors of the vehicle, refer to page 35.

The system can be used to set a speed limit,

for instance to prevent the vehicle from ex-

ceeding speed limits.

Additional information:

General information

Exceeding the speed limit

When the vehicle speed exceeds the set speed

limit, a warning is issued.

The system switches off automatically in the

following situations, for example:

▷

When the engine is switched off.

The speed limit can be exceeded intentionally.

When Cruise Control is switched on.

ally, a signal sounds.

Press the rocker switch up or down repeatedly

until the desired speed limit is set.

▷

When the speed limit is reduced to be-

low the current vehicle speed, the signal

sounds after some time.

▷

Each time the rocker switch is pressed

to the resistance point, the speed limit in-

creases or decreases by 1 mph/1 km/h.

▷

When the speed limit is intentionally ex-

ceeded by stepping on the accelerator

pedal all the way down, there is no signal.

The use of the system can lead to an in-

creased risk of accidents in the following sit-

uations, for instance:

▷

On winding roads.

Cruise Control

With high traffic volume.

On slippery roads, in fog, snow, or wet

conditions, or on a loose road surface.

Principle

With the Cruise Control, a set speed can be ad-

justed using the buttons on the steering wheel.

The system maintains the set speed. The sys-

tem accelerates and brakes automatically as

needed.

There is a risk of accident, injury, or property

damage. Only use the system if driving at

constant speed is possible.

General information

The system can be activated starting at

20 mph/30 km/h.

Warning

The set speed can be incorrectly adjusted or

called up by mistake. There is a risk of acci-

dent, injury, or property damage. Adjust the

set speed to the traffic conditions. Watch sur-

rounding traffic closely and actively intervene

where appropriate

Depending on the vehicle setting, the cruise

control settings may change under certain

conditions. For instance, acceleration can

change depending on the driving mode.

CONTROLS

For instance, two-wheeled vehicles may not be

detected.

Cornering

Deceleration

The system does not decelerate in the follow-

ing situations:

▷

For pedestrians or similarly slow-moving

road users.

▷

Depending on the vehicle equipment and

national availability, for red traffic lights.

When the set speed is too high for a curve,

the speed is reduced slightly. Because curves

may not be anticipated in advance, drive into a

curve at an appropriate speed.

▷

For cross traffic.

For oncoming traffic.

Merging vehicles

The system has a limited detection range. Sit-

uations can arise in tight curves where a vehi-

cle driving ahead will not be detected or will be

detected very late.

If a vehicle driving ahead of you suddenly

merges into your lane, the system may not be

able to automatically restore the selected dis-

tance. It may not be possible to restore the se-

lected distance in certain situations, including if

you are driving significantly faster than vehicles

driving ahead of you, for instance 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 making an evasive maneuver, if needed.

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 decel-

erates you may compensate for it by briefly

accelerating. After releasing the accelerator

pedal the system is reactivated and controls

speed independently.

Driving off

In some situations, the vehicle cannot drive off

automatically; for example:

▷

On steep uphill grades.

In front of bumps in the road.

In these cases, step on the accelerator pedal.

ing style to traffic conditions. Watch the sur-

rounding traffic situation closely, be ready to

take over steering and braking at any time,

Short-term interruptions for vehicles that

are already recognized.

Drive attentively, and react to the current sur-

rounding traffic situation. If necessary, inter-

vene actively, for instance by braking, steering

or making an evasive maneuver.

Drive power

The set speed is also maintained downhill. The

speed may not be maintained on uphill grades

if the drive power is insufficient.

Warning

In ECO PRO driving mode, the vehicle may

exceed or drop below the set desired speed

in some situations, for instance on downhill or

uphill grades.

The set speed can be incorrectly adjusted or

Parking assistance systems

Safety information

General information

The parking assistance systems include differ-

ent individual systems. The individual systems

help the driver when parking, maneuvering, or

reversing by providing various assistance func-

tions, sensors, and camera views.

Warning

The system cannot serve as a substitute for

the driver’s personal judgment in assessing

the traffic situation. Based on the limits of

the system, it cannot independently react

to all traffic situations. There is a risk of

accident. Adjust driving style to traffic condi-

tions. Check surrounding traffic and vehicle's

surroundings closely and actively intervene

where appropriate.

Warning

Due to high speeds when the Park Distance

layed due to physical circumstances. There is

a risk of injury or risk of damage to property.

Avoid approaching an object too fast. Avoid

Turning on automatically

The system switches on automatically in the

following situations:

Signal tones

General information

▷

With the engine running, when selector

lever position R is engaged.

An intermittent tone indicates when the vehicle

is approaching an object. If, for example, an

object is detected at the front left of the vehi-

cle, a signal tone sounds from the front left

speaker.

▷

Depending on the equipment version: while

approaching detected obstacles at a speed

lower than approx. 2.5 mph/4 km/h. The

activation distance depends on the situa-

tion in question.

The shorter the distance to the object, the

shorter the intervals.

You may switch automatic activation when ob-

stacles are detected on and off.

When the distance to a detected object is less

than approx. 8 in/20 cm, a continuous tone is

sounded.
