Driving safety systems
When the distance to the forward vehicle is
too small, the distance warning lampl
comes on in the instrument cluster. If you
approach the forward vehicle very quickly,
you will hear a warning tone.
If you do not apply the brakes yourself or
maneuver around a sensed obstacle, the
vehicle will automatically initiate light
braking. PRE-SAFE
® (page 56) is activat-
ed when the distance to the vehicle ahead
at your current speed is so close that
PRE-SAFE
® Brake will not be capable of
slowing the vehicle sufficiently.

PRE-SAFE® Brake will only respond with
brake assistance if it has clearly detected an
object. Detection can be impeded by

dirty or covered sensors

snowfall or heavy rain

disturbance from other radar sources

strong radar reflection such as in park-
ing garages
PRE-SAFE
® Brake uses radar signals that
are not reflected well by narrow objects and
absorptive materials. For this reason BAS
Plus will not react to

persons and animals

approaching traffic or cross-traffic
PRE-SAFE
® Brake may not detect narrow ve-
hicles driving in front of you, such as motor-
cycles and vehicles driving offset from your
vehicle center.

Driving safety systems
PRE-SAFE® Brake can react to stationary
obstacles such as standing or parked vehi-
c le s a t roa d s pe eds of up to ap proxim a tel y
40 mph (70 km/h).
Activating and deactivating: Activate
or deactivate PRE-SAFE® Brake using
the instrument cluster control system
(
page 268).
After the function has been activated,
indicator : appears on the
left-hand side of the multifunction dis-
play.PRE-SAFE
® Brake does not always clearly
interpret complex traffic situations. If a vi-
sual and/or acoustic warning is issued in
an uncritical driving situation, or if the ve-
hicle brakes lightly, you can interrupt the
PRE-SAFE
® Brake maneuver by

pressing down all the way on the accel-
erator or using kickdown

releasing the brake pedal
The PRE-SAFE
® Brake maneuver is termi-
nated immediately when

you avoid the obstacle by evasive
steering

you drive less than 9 mph (15 km/h)

an obstacle can no longer be identified
ahead of you

the system no longer senses the risk of
a collisionAfter a hard collision or damage to the
front of the vehicle from an accident, have
the settings and operation of the radar
sensors checked by an authorized
Mercedes-Benz Center.
Warning!G
If you do not receive visual or acoustic warn-
ing signals, PRE-SAFE® Brake has either not
recognized the collision risk, has been deac-
tivated or is malfunctioning. Apply the
brakes yourself to avoid a collision.
iPRE-SAFE® Brake will remain passive while
DISTRONIC Plus* is switched on (

Notes about handling CDs/DVDs

Only hold discs by the edge.

Handle discs carefully to prevent play-
back problems.

Avoid getting scratches, fingerprints
and dust on discs.

Clean discs from time to time with a
commercially-available cleaning cloth.
Do not wipe them with a circular mo-
tion, but only in straight lines from the
center outwards.

Only use a pen designed for such a pur-
pose to label discs.

Place discs back in their boxes after
use.

Protect discs from heat and direct sun-
light.

Warning!G
Only insert a CD or DVD when the vehicle is
stationary. There is a risk of accident by be-
ing distracted from road and traffic condi-
tions if you load a CD/DVD while the vehicle
is in motion.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
iIf the CD/DVD has a printed side, this must
face upwards when the CD/DVD is inserted. If
neither side is printed, the side to be played
should face downwards.
iEach magazine tray button3 indicates the
status of the corresponding magazine tray by
means of an LED.

Safety precautions
Warning!G
For safety reasons, only enter a destination
when the vehicle is stationary. When the ve-
hicle is in motion, a passenger should enter
the destination. Study manual and select
route before driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
COMAND calculates the route to the desti-
nation without taking account of the follow-
ing, for example:

Traffic lights

Stop and right-of-way signs

Parking or stopping prohibited areas

Lane merging

Other road and traffic rules and regula-
tions

Narrow bridges
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual
road/traffic situation. DVD maps do not
cover all areas nor all routes within an area.
For example, if the traffic routing has been
changed or the direction of a one-way road
has been reversed.
For this reason, you must always observe
applicable road and traffic rules and regula-
tions during your journey. Road and traffic
rules and regulations always have priority
over the navigation commands generated by
the system.Warning!G
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.

COMAND navigation system (route guidance)
Route guidance
COMAND guides you to the destination us-
ing navigation commands in the form of
audible navigation announcements and
route guidance displays.
If, for any reason, you do not follow the
navigation commands or if you leave the
calculated route, COMAND automatically
calculates a new route to the destination.
If the map data contains the relevant infor-
mation, COMAND tries to avoid roads that
only have limited access, e.g. roads closed
to through-traffic and non-residents.Roads that have time restrictions (e.g.
closed on Sundays and public holidays) are
not considered for route guidance, if the
digital map contains the relevant informa-
tion.
Examples of displays and announce-
ments for a driving maneuver
Driving maneuvers have three phases:

Preparation phase

Announcement phase

Maneuver phase

COMAND navigation system (route guidance)
During route guidance, the display is divid-
ed. On the right-hand side you will see the
direction arrow showing the compass
heading to the destination.
On the left-hand side of the display you will
see the map with the suggested route. The
suggested route is highlighted blue. How-
ever, it may not be possible to follow the
suggested route because, for example, the
road is closed or not open for car traffic.
If, during route guidance, COMAND leads
you back into a fully digitalized area, route
guidance will simply continue in the usual
manner.Off-road and off-map
Route guidance to an off-road destina-
tion
COMAND can guide you to destinations
within the area covered by the digital map,
even if a destination is not located at a
road known to the system.These destinations are shown as off-road
destinations, which you can enter using
the map, for example.
In these cases, COMAND guides you for as
long as possible with navigation announce-
ments and displays on roads known to the
system.
Shortly before you reach the last known
the point to leave the digitized road net-
work, you will hear the announcement “The
destination is nearby. Follow the arrow on
the display”.
You will then see an arrow that indicates
the direction to the off-road destination.
When the off-road destination is close to
the road, “Area of dest. reached” appears
in addition below the arrow.
The section of the route from the last
known point on the map to the off-road
destination is indicated with a dashed line
after a certain length. It simply shows the
direction to the off-road destination with-
out taking account of any type of obstacles
in the way.
Warning!G
The COMAND navigation system may direct
you to off-road routes that your vehicle may
not be capable of traversing through without
damaging your tires, wheels or vehicle. It is
the driver’s sole responsibility to determine
the suitability of the route. Off-road routes
may be of varying conditions and their ap-
propriateness for use may be affected by
various factors such as time of day, time of
year and immediate weather conditions that
cannot be judged or taken into consider-
ation by the COMAND system.

Important notes
Warning!G
For safety reasons, you should only select a
destination when the vehicle is stationary.
While the navigation system provides direc-
tional assistance, the driver must remain fo-
cused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system’s audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their ob-
servance always remains in the driver’ per-
sonal responsibility. DVD maps do not cover
all areas nor all routes within an area.
Traffic regulations always have priority over
any route recommendations given.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 13.5 m) every second.
During route guidance, you will not receive
information on:

traffic lights

stop and yield signs

parking or stopping zones

one-way streets

narrow bridges, or

other traffic regulation data.
You should therefore always strictly observe
traffic regulations while driving. Drive care-
fully and always obey traffic laws and road
signs, even if they contradict navigation sys-
tem instructions.
Warning!G
Please do not use the Voice Control System
in an emergency, as the tone of your voice
may change in a stressful situation. This
could cause a delay in completing your
phone call in a timely manner. This could
distract you in an emergency situation and
cause you to be involved in an accident.
Warning!G
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.

Seats
Seat adjustment
Warning!G
All seat, head restraint adjustments, as well
as fastening of seat belts, must be done be-
fore the vehicle is put into motion.
Warning!G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
belts are properly positioned on the body.
Warning!G
Your seat must be adjusted so that you can
correctly fasten your seat belt
(
page 360).
Observe the following points:

Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel.

Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate the
controls properly.

Adjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports
the back of the head at eye level.

Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or SmartKey with
KEYLESS-GO* removed from the starter
switch or the SmartKey with KEYLESS-GO*
removed from the vehicle, the power seats
can be operated when the respective door is
open. Therefore, do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
