2018 MERCEDES-BENZ CLA COUPE warning

iWhen you switch off the engine, the last
speed stored is cleared.
Distance Pilot DISTRONIC
General notes
Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tanc etot he vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically to avoid exceedingt he set speed or to
maintain the designated distanc efrom the vehi-
cle in front.
If Distance Pilot DISTRONIC detect sthat there is
ar isk of acollision, you will be warned visually
and acoustically. Without your intervention, Dis-
tanc ePilot DISTRONIC cannot prevent acolli-
sion. An intermittent warning ton ewill then
sound and the distanc ewarning lamp will light
up in the instrument cluster. Brake immediately
in order to increase the distanc etothe vehicle in
frontort ake evasive action provided it is safe to
do so.
Distance Pilot DISTRONIC operates in the range
between 0mph (0 km/h) and 120 mph
(200 km/h).
Change into alower gear in good time on long
and steep downhill gradients .This is especially
importan tifthe vehicle is laden. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brake system and
preventst he brakes from overheatin gand wear-
ing too quickly.
Do not use Distance Pilot DISTRONIC on roads
with steep gradients.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Sinc eDistance Pilot DISTRONIC transmits radar
waves, it can resemble the radar detectors of
the responsible authorities. You can refer to the
relevant chapter in the Operator' sManual if
questions are asked about this.

Important safety notes
GWARNING
Distance Pilot DISTRONIC does not react to:
Rpeople or animals
Rstationary object sonthe road, e.g. stopped
or parked vehicles
Roncoming vehicles and crossingt raffic
As aresult, Distance Pilot DISTRONIC may
neither give warnings nor intervene in such
situations. There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
GWARNING
Distance Pilot DISTRONIC cannot always
clearly identif yother road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may:
Rgive an unnecessary warning and then
brake the vehicle
Rneither give awarning nor intervene
Raccelerateorb rake unexpectedly
There is arisk of an accident.

Driving and parking

To activate Distance Pilot DISTRONIC, the fol-
lowing conditions must be fulfilled:
Rthe engine must be started. It may take up to
two minutes of driving before Distance Pilot
DISTRONIC is ready for use.
Rthe electric parking brake must be released.
RESP®must be active, but not intervening.
RParking Pilot must not be activated.
Rthe transmission must be in positionh.
Rthe driver's door must be closed when you
shift fromjtoh or your seat belt must be
fastened.
Rthe front-passenger door must be closed.
Rthe vehicle must not skid.
Activating
XBriefly pull the cruise control lever towards
you ?,u p: or down ;.

Parking Pilot
General notes
Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. Aparking symbol indicates asuit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting aparking space. Park-
ing Assist PARKTRONIC is also available
(
Ypage 161).
Important safety notes
Parking Pilot is only an aid. It is not areplace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting aparking
space. Make sure that no persons, animals or
object sare in the maneuvering range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable.
GWARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
result in acollision with another road user.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Parking Pilot
parking procedure.
!If unavoidable,y ou should drive over obsta-
cles such as curbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tires.
Parking Pilot may also display spaces not suita-
ble for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
RSnowfall or heavy rain may lead to aparking
space being measured inaccurately.
RPay attention to the warning messages of
Parking Pilot PARKTRONIC during the parking
procedure (
Ypage 162).
RYou can intervene to correct the steering pro-
cedure at any time. Parking Pilot will then be
canceled.
RWhen transporting aload that protrudes from
your vehicle, you must not use Parking Pilot.
RNever use Parking Pilot when snow chains are
mounted.
RMake sure that the tire pressures are always
correct.T his hasadirect influence on the
parking characteristics of the vehicle.
Use Parking Pilot for parking spaces that are:
Rthat are paralleloratr ight-angles to the direc-
tion of travel
Ron straight roads, not bends
Ron the same level as the road, e.g. not on the
pavement
Detecting parking spaces
Object slocated above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula-
ted, e.g. overhanging loads, truck overhangs or
loading ramps. Parking Pilot may therefore
guide you into the parking space too early.
Parking Pilot does not assist you parking in
spaces perpendicular to the direction of travel if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to alow
obstacle such as alow curb
Ryou forward-park
Parking Pilot does not assist you parking in
spaces parallelorp erpendicular to the direction
of travel if:
Rthe parking space is on acurb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. atree, apost or atrailer
