MERCEDES-BENZ CLA 2014 Owners Manual

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

is operational at speeds of up to
approximately 22 mph (35 km/h). While in
operation, the system independently locates

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.

opens. Only once the maneuvering process
has been completed and the rear view camera
has switched off does the flap close again. For
technical reasons, the flap may remain open
briefly after the rear view camera has been
deactivated. If you switch off the engine, the
flap will also close.
iThe text of messages shown in the
COMAND display depends on the language
setting. The following are examples of rear
view camera messages in the COMAND
display.

ATTENTION ASSIST
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the range between 50 mph
(80 km/h) and 112 mph (180 km/h).
If ATTENTION ASSIST detects typical
indicators of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests you take a break.
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognize fatigue
or increasing inattentiveness in time or fail to
recognize them at all. The system is not a
substitute for a well-rested and attentive
driver.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
Ryour personal driving style, e.g. steering
characteristics
Rjourney details, e.g. time of day and length
of journey
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
Rif the road condition is poor, e.g. if the
surface is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
Rif you are predominantly driving slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)
Rif you are currently using COMAND or
making a telephone call with it
Rif the time has been set incorrectly
Rin active driving situations, such as when
you change lanes or change your speed
Warning and display messages in the
multifunction display
XActivate ATTENTION ASSIST using the on-
board computer (Ypage 204).
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after
your journey has begun. You then hear an
186Driving systems
Driving and parking

intermittent warning tonetwice and the
Attention Assist: Take a Break!
message appears in the multifunction
display.
XIf necessary, take a break.
XPress theorbutton to confirm
the message.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. The
preconditionfor this is that
ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
ATTENTION ASSIST is reset when you
continue your journey and starts assessing
your tiredness again if:
Ryou switch off the engine.
Ryou take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break.
When ATTENTION ASSIST is deactivated, the
symbol appears in the multifunction
display in the assistance graphic display.
Speed Limit Assist
General notes
Speed Limit Assist shows you detected speed
limits in the multifunction display.Data from
the navigation system is also used for this
purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected,
it is shown in the multifunction display. If
Speed Limit Assist does notdetectany traffic
signs, the speed limit from the digital road
map is used and shown in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windshield.
Speed Limit Assist camera
Important safety notes
Speed Limit Assist is only an aid and does not
always detect traffic signs with information
aboutthe maximum permissible speed.
Traffic signs always have priority over the
Speed Limit Assist display.
The system may be impaired or may not
function if:
Rthere is poor visibility, e.g. due to snow,
rain, fog or spray
Rthere is glare, e.g. from the sun or from
oncoming traffic
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera
Rthe traffic signs are covered, for instance
by dirt, snow or trees
Rthe traffic signs are poorly illuminated
Rthere are ambiguous traffic signs, for
instance near roadworks or on multi-lane
roads

Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist (Ypage 188) and Lane Keeping
Assist (Ypage 190).
Blind Spot Assist
General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph(30 km/h). A warning
display in the exteriormirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turnsignal to change lanes,
you will also receive a visual and audible
collision warning. For this purpose, Blind Spot
Assist uses sensors in the rear bumper.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing theminthe blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.
