The warning lights in the instrument cluster indicate certain functions or
faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test.
If the tested systems are OK, the corresponding warning lights go out a few
seconds after switching on the ignition or after starting the engine.
Warning lights in the display
Depending on the importance the warning light
(danger) or
(warning) illu-
minate along with some of the warning lights in the list with the warning
lights.
Depending on vehicle specification, some warning lights may be displayed in
colour on the display. For example. the coolant warning lamp may be represen-
ted as follows.
▶ - Segment Display / monochromatic (“black and white”) MAXI DOT display
▶ - colour MAXI DOT displayWARNING■
Ignoring illuminated warning lights and related messages or instructions
in the display of the instrument cluster may lead to serious personal injury
or damage to the vehicle.■
If you have to stop for technical reasons, then park the vehicle at a safe
distance from the traffic, switch off the engine and switch on the hazard
warning lights » page 71. Place the warning triangle at the prescribed dis-
tance.
■
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 206, Engine compartment .

32Using the system
If, after a short drive, the indicator light does not go out, there is a system er-
ror.
Seek help from a specialist garage.
Other incidents
The illumination of the warning light
can have the following reasons.
▶ The vehicle is loaded on one side. Distribute loads as evenly as possible.
▶ The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
▶ Snow chains are mounted.
▶ A wheel has been changed.
CAUTION
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light can be delayed or does not light up at all.
Brake linings

flashes – the right turn signal is switched on.
If there is a fault in the turn signal system, the warning light flashes at twice
its normal rate. This does not apply when towing a trailer.
When the hazard warning light system is switched on, this will cause all of the
turn signal lights as well as both warning lights to flash.
Trailer turn signal lights
Read and observe
on page 32 first.
flashes – the trailer turn signal lights are switched on.
If a trailer is hitched and the warning light is not flashing, one of the trailer
turn signal lights has failed.

CAUTION
The objects shown in the display can be closer or even further away than they
appear. This is especially the case in the following situations.■
Protruding objects, such as the rear of a truck and the like.
■
When driving from a horizontal surface into a slope or a depression.
■
When driving from a slope or a depression onto a horizontal surface.
Note
The distance between the orientations behind the vehicle may vary slightly
depending on the load condition of the vehicle rear and on the road inclination.ABCD153Assist systems
WARNING (Continued)■The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
When driving around “sharp” bends.
■
When riding on a steep gradient / high slope.
■
When driving through places where metal objects (such as metal build-
ings, railway tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.
OperationFig. 202
Instrument cluster display: Examples of ACC displays
Fig. 203
Instrument cluster display: Examples of ACC status displays
Read and observe
on page 163 first.
The ACC allows you to set a speed of 30 - 160 or 210 km / h (depending on
equipment) and the distance to the vehicle ahead in the range of a very short
to a very long distance.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
The ACC can detect a vehicle that is up to approx. 150 m ahead using the radar
sensor.

Regulation deactivated - no speed stored.
Regulation active - vehicle detected (in the colour display the digits of the

Note to reduce speed
If the delay of the ACC is insufficient in relation to the vehicle in front, in the instrument cluster, the warning light lights up and the display shows the
following message.Apply the brake!
Regulation according to the vehicle in the adjacent lane
During regulation your vehicle may be regulated according to the vehicle in the adjacent lane.
This could occur at speeds above about 80 km / h when your vehicle is moving
faster than the vehicle in the adjacent lane on the driver's side. The display
shows the detected vehicle is in the adjacent lane.
Note
Some ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.
Automatic stop-start
Read and observe
on page 163 first.
Vehicles with an automatic transmission can decelerate to a standstill and
start moving again using the ACC.
Decelerate to a standstill
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your
vehicle to a standstill.
34Starting to drive again after a holding period
As soon as the vehicle ahead starts moving again after a holding period, your
vehicle will also move and the speed will continue to be regulated.
If the preceding vehicle starts moving again after a long break, then to contin-
ue the regulation press the accelerator pedal or lever to position

Changing the speed by adopting the current speed () - requirements
The ACC is activated.
The vehicle is moving at a speed other than that which is stored.
Note
■
If during control the speed is increased by pressing the accelerator, control is
temporarily stopped. Upon releasing the accelerator, control is automatically
resumed.■
If during control the speed is reduced by applying the brake, control is stop-
ped. Control needs to be restarted in order to resume » page 166.
■
If the vehicle is controlled by a lower speed than the stored speed, then
the current speed is stored the first time the key is pressed. Press the key
again
and the speed is reduced in increments of 1 km/h.

Note
■
If the proximity is changed in infotainment, the change will only come into
effect after a subsequent activation of the ACC.■
The proximity is dependent on the speed. The higher the speed, the greater
the proximity to the vehicle ahead.
■
On wet roads, a longer time interval to the vehicle ahead should always be
selected than on dry roads.
Special driving conditionsFig. 205
Special conditions: Cornering / narrow vehicles or vehicles trav-
elling side by side
Fig. 206
Special conditions: Lane changes of other vehicles / stationary
vehicles
Read and observe
on page 163 first.
The following and similar situations require special attention of the driver.
When cornering
When driving around long bends the ACC may respond to a vehicle in the adja-
cent lane » Fig. 205 -
. Your own vehicle is regulated with respect to this ve-
hicle and will no longer respond to the vehicle ahead.
In such cases, control should be disabled by accelerating, applying the brake or
pressing the button on the operating lever
