i If RACE START is used repeatedly within a
short period of time, it is only available

certain distance. 4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip.
If you fail to adapt your driving style, 4MATIC can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic con-
ditions. 4MATIC 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.
If a drive wheel spins due to insufficient grip:
R Only depress the accelerator pedal as far as
necessary when pulling away.
R Accelerate less when driving.
! Never tow the vehicle with one axle
raised. This may damage the transfer case. Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground or
be fully raised. Observe the instructions for towing the vehicle with all wheels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and four sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for Driving systems

Important safety notes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas- ure the road on both sides of the vehicle. A
suitable parking space is indicated by the
parking symbol. You receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 171).
Parking Guidance is only an aid. It is not a
replacement for your attention to your imme-
diate surroundings. You are always responsi- ble for safe maneuvering, parking and exitinga parking space. When maneuvering, parking
or pulling out of a parking space, make sure
that there are no persons, animals or objects
in the area in which you are maneuvering. G
WARNING
If objects are located above the detection
range, Parking Guidance may provide steering instructions too soon. You may cause a colli-
sion as a result. There is a risk of an accident.
If objects are located above the detection
range, stop and switch off Parking Assist.
! Pay particular attention to low objects or
objects with flat surfaces, such as trailer
drawbars, posts, cross beams and curbs.
These types of objects cannot be detected by Parking Guidance and may damage the
vehicle.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable. Driving systems
175Driving and parking Z

Use Parking Guidance for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat curbs
Parking tips:
R On narrow roads, drive as close to the park-
ing space as possible.
R Parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 173) warning messages during the
parking procedure.
R When transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
R Never use Parking Guidance with snow
chains or an emergency spare wheel moun-
ted.
R Make sure that the tire pressures are
always correct. This has a direct effect on
the steering instructions.
R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the location. In some cases, Parking Guidance
may guide you too far or not far enough into
a parking space. In some cases, it may also
lead you across or onto the curb. If neces-
sary, cancel the parking procedure with
Parking Guidance.
! 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. Detecting parking spaces 0043
Detected parking space on the left
0044 Parking symbol
0087 Detected parking space on the right
Parking Guidance is automatically activated
when you drive forwards. The system 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.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol 0044as
a status indicator in the instrument cluster.
When a parking space has been detected, an arrow towards the right 0087or the left 0043also
appears. Parking Guidance only displays
parking spaces on the front-passenger side
as standard. Parking spaces on the driver's
side are displayed as soon as the turn signal
on the driver's side is activated. To park on
the driver's side, you must leave the driver's
side turn signal switched on until you have
engaged reverse gear.
Parking Guidance will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 5 ft (1.5 m) wide
R that are at least 4.3 ft (1.3 m) longer than
your vehicle
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) away from it. 176

Rear view camera
Rear view camera 0043is an optical parking and
maneuvering aid. It shows the area behind
your vehicle in the COMAND display.
The rear view camera is located in the handle
strip of the trunk lid.
Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your imme- diate surroundings. You are always responsi-
ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there are no persons, animals or objects in the area
in which you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
R if the trunk lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter R
if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In this
event, have the camera position and setting checked at a qualified specialist workshop
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, bicycle rack).
View through the camera The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
The rear view camera may show a distorted
view of obstacles, show them incorrectly or
not at all. The rear view camera does not show objects in the following positions:
R very close to the rear bumper
R under the rear bumper
R in the area immediately above the tailgate
handle
! Objects not at ground level may appear to
be further away than they actually are, e.g.:
R the bumper of a parked vehicle
R the drawbar of a trailer
R the ball coupling of a trailer tow hitch
R the rear section of an HGV
R a slanted post
Use the guidelines only for orientation.
Approach objects no further than the bot-
tom-most guideline.
Activating the rear view camera X
Make sure that the SmartKey is in position
2 in the ignition lock.
X Make sure that the rear view camera func-
tion is selected in COMAND (see the sepa-
rate operating instructions for COMAND).

ATTENTION ASSIST
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 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 indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests you take a break.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey 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:
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)
R if you are currently using COMAND or mak-
ing a telephone call with it
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed Warning and display messages in the
multifunction display X
Activate ATTENTION ASSIST using the on-
board computer (Y page 200).
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your journey has begun. You then hear an inter-
mittent warning tone twice and the Atten‐ Atten‐
tion
tion Assist:
Assist: Drowsiness
Drowsiness detected
detectedmes-
sage appears in the multifunction display.
X If necessary, take a break.
X Press the 0076button to confirm the mes-
sage.
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 precon-
dition for this is that ATTENTION ASSIST still
detects typical indicators of fatigue or
increasing lapses in concentration.
ATTENTION ASSIST is reset when you con-
tinue your journey and starts assessing your
tiredness again if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break.
The assistance graphic shows the 00D7sym-
bol when ATTENTION ASSIST is deactivated
(Y page 199). Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 179) and Lane Keeping
Assist (Y page 181).
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 Driving systems
179Driving and parking Z

approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will
also receive a visual and audible collision
warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes.
For Blind Spot Assist to assist you, the radar
sensor system must be operational.
Important safety notes
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles. G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles 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 care-
fully, and maintain a safe lateral distance.

In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else cover-
ing the sensors
R poor visibility, e.g. due to fog, heavy rain,
snow or spray
R narrow vehicles, e.g. motorcycles or bicy-
cles
R the road has very wide lanes
R the road has narrow lanes
R you are not driving in the middle of the lane
R there are barriers or similar lane borders
Vehicles in the monitoring range are then not indicated. Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may be the case if there are vehicles driving at the
inner edge of their lanes. 180
