warning MERCEDES-BENZ CLA 2014 Owners Manual

GWARNING
DISTRONIC PLUS cannot always clearly
identify other road users and complextraffic
situations.
In such cases, DISTRONIC PLUS may:
Rgive an unnecessary warning and then
brake the vehicle
Rneither give a warning nor intervene
Raccelerate unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, in particular when warned to do so by
DISTRONIC PLUS.
GWARNING
DISTRONIC PLUS brakes yourvehicle with up
to 50% of the maximum possible deceleration.
If this braking force is insufficient, DISTRONIC
PLUS warns you visually and audibly.There is
a risk of an accident.
In such cases, apply the brakes yourself and
try to take evasive action.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
Rwhen towing the vehicle
Rin the car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of accident nor override the laws of physics.
DISTRONIC PLUS cannot take into account
the road, traffic and weather conditions.
DISTRONIC PLUS is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
Do not use DISTRONIC PLUS:
Rin road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radar sources
Rstrong radar reflections, for example, in
parking garages
If DISTRONIC PLUS no longer detects a
vehicle in front, DISTRONIC PLUS may
unexpectedly accelerate the vehicle to the
stored speed.
This speed may:
Rbe too high if you are driving in a filter lane
or an exit lane
Rbe so high when driving in the right-hand
lane that you overtake vehicles in the left-
hand lane
Rbe so high when driving in the left-hand lane
that you overtake vehicles in the right-hand
lane
If there is a change of drivers, advise the new
driver of the speed stored.

Driving with DISTRONIC PLUS
Pulling awayand driving
iThe vehicle can also pull away when it is
facing an unidentified obstacle or is driving
on a differentline fromanothervehicle. The
vehicle then brakes automatically. There is
a risk of an accident. Be ready to brake at
all times.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
XIf you want to pull away with
DISTRONIC PLUS:remove your foot from
the brake pedal.
XBriefly pull cruise control (Ypage 166)lever
towards you!.
or
XAccelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If no vehicle is detected in front, your
vehicle accelerates to the set speed.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle
in fronthas slowed down, it brakes your
vehicle.Inthis way, the distance you have
selected is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
The vehicle is only accelerated up to the
speed you have stored.
Selecting the drive program
DISTRONIC Plus supports a sporty driving
style when you have selected theSorM
driving program (Ypage 146). Acceleration
behind the vehicle in frontorto the set speed
is then noticeably more dynamic. If you have
selected theEdriving program, the vehicle
accelerates more gently. This setting is
recommended in stop-and-start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
Ryou are driving faster than 43.5 mph
(70 km/h)
RDISTRONIC PLUS is maintaining the
distance to a vehicle in front
Ryou switch on the appropriate turn signal
RDISTRONIC PLUS does not detect a danger
of collision
If these conditions are fulfilled, yourvehicle
is accelerated. Acceleration will be
interrupted if changing lanes takes too long
or if the distance between your vehicle and
the vehicle in frontbecomes too small.
iWhen changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.

Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle.Aparking symbol
indicates a suitable parking space. Active
steering interventioncan assistyou during
maneuvering and parking. You may also use
PARKTRONIC (Ypage 175).
Important safety notes
Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Make sure that
no persons, animals or objects are in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active
Parking Assist parking procedure.
!If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces

Driving and parking

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 a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(Ypage 176) warning messages during the
parking procedure.
RYou can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
RWhen transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are
always correct. This hasadirectinfluence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
Rthatare parallel or at right-angles to the
direction of travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles.
GWARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Ypage 175).
Active Parking Assist does not support you
with parking spaces at right-angles to the
direction of travel if:
Rtwo parking spaces are located directly
next to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou park forwards
Active Parking Assist does not support you
with parking spaces that are parallel or at
right-angles to the direction of travel if:
Rthe parking space is onacurb
Rthe parking space is apparently blocked,
for example by foliage or grass paving
blocks
Rthe range of movement is too small
Rthe parking space is bordered by an
obstacle which is notclearly defined such
as a tree or a trailer

and measures parking spaces on both sides
of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rthat are parallel or at right-angles to the
direction of travel
Rthat are parallel to the direction of travel
and at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel
and at least 39.5 in (1.0m) longer than your
vehicle
Rthat are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
iIn the case of parking spaces that are at
right angles to the direction of travel,
please ensure that the parking space is
long enough to accommodate your vehicle.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol as a
status indicator in the instrument cluster.
When a parking space has been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the
button on the multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right-angles to the direction of travel.
Aparking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.

Parking tips:
RThe way yourvehicle is positioned in the
parking space after parkingis dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should
cancel the parking procedure with Active
Parking Assist.
RYou can also engage forward gear
prematurely.The vehicle redirects and
does not drive as far into the parking space.
Should a gear be changed too early, the
parking procedure will be canceled. A
sensible parking position can no longer be
achieved from this position.
Exitingaparking space
In order that Active Parking Assist can
support you whenyou exit the parking space:
Rthe border of the parking space must be
high enough.Acurb is too small, for
example.
Rthe border of the parking space must not
be too wide, as the position of the vehicle
must not exceed an angle of 45° to the
starting position as it is maneuvering into
the parking space.
Ra maneuvering distance of at least 3.3 ft
(1.0m) must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
