restraint appropriate

to the age and size of
the child.
X Make sure the infant or child is properly
secured at all times while the vehicle is in
motion. G
Warning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle,

even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle, such as seat adjustment, steering wheel
adjustment, or the memory function
If children

open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned by these
parts. G
Warning!
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident
Infant and child restraint systems G
Observe Safety notes, see page 51.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap/shoulder

belts except the driver’s seat

Introduction
This section contains information about the
following driving safety systems:
R ABS ( Antilock Brake System)
R Adaptive Brake
R Adaptive Brake Lights
R BAS ( Brake Assist System)
R BAS PLUS ( Brake Assist System PLUS)
R EBP ( Electronic Brake Proportioning)R
ESC ( Electronic Stability Control)
R PRE-SAFE ®
Brake ( Preventive Occupant
Safety System Brake)
i In winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
achieved with winter tires, or snow chains
as required.
Safety notes G
Warning!
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural

laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear. 56

ABS
G
Observe Safety notes, see page 56. G
Warning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
The Antilock Brake System (ABS) regulates
the brake
pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
Braking At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
X
Keep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking

power and the ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver X
Keep continuous full pressure on the brake
pedal. G
Warning!
If the ABS malfunctions, other driving safety
systems such

as the BAS or the ESC are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance. BAS
G
Observe Safety notes, see page 56.
The Brake Assist System (BAS) operates in
emergency situations.

If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
X Apply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated. G
Warning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the

braking distance may increase. BAS PLUS
The Brake Assist System PLUS (BAS PLUS)
operates in

emergency braking situations and
uses radar sensors to assess the traffic
situation. BAS PLUS assists you in braking at
speeds above approximately 20 mph
(30 km/h).
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 216). Canadian
law does not permit the use of the radar Driving safety systems

d2ureepe, Version: 2.11.8.1 2009-05-15T11:47:50+02:00 - Seite 57 Z

BAS PLUS uses radar signals that are not
reflected well by narrow objects and
absorptive materials. For this reason BAS
PLUS will not react to persons, animals, and
approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles
driving in front of you, such as motorcycles
and vehicles driving offset from your vehicle
center.
After a hard collision or damage to the front
of the vehicle from an accident, have the
adjustment and operation of the radar
sensors checked
by an authorized Mercedes-
Benz Center.
If BAS PLUS is not available due to a radar
sensor malfunction, the braking system will
continue to function normally with full brake
boost and full standard BAS function. Adaptive Brake
Adaptive Brake provides a high level of
braking safety as well as increased braking
comfort. Adaptive Brake takes driver and
vehicle characteristics into consideration,
thus achieving an optimal braking effect.
In addiditon, Adaptive Brake provides the
HOLD function

(Y page 316) and the hill-start
assist system ( Y page 315).
For more information on the brake system,
see ( Y page 398). Adaptive Brake Lights
i This function is only available for the
CL 600 (USA only).
The brake lamps flash in quick intervals
R while you are braking hard at a speed of
more than 30 mph (50 km/h)
R when you are braking with the aid of BAS
R when you are braking with the aid of BAS
PLUS.
This helps to alert drivers behind you. If you bring the car to a complete stop by hard
braking at a speed of more than 40 mph
(70
km/h),

the hazard warning flasher comes
on automatically as soon as the vehicle is at
a standstill. While the vehicle is stationary,
the brake lamps are continuously lit up. Once
you drive faster than 6 mph (10 km/h)
afterward, the hazard warning flasher goes
out. EBP
G
Observe Safety notes, see page 56.
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
the rear

brakes to supply a greater proportion
of the braking effort in straight-line braking
without a loss of vehicle stability. G
Warning!
If the EBP malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics. ESC
G
Observe Safety notes, see page 56.
The Electronic Stability Control (ESC) is
operational as

soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESC recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels and by limiting the engine output, the
ESC works to stabilize the vehicle. The ESC is
especially useful while driving off and on wet
or slippery road surfaces. The ESC also
stabilizes the vehicle during braking and
steering maneuvers. Driving safety systems

Always pay attention to traffic conditions
even while the PRE-SAFE
®
Brake is switched
on. Otherwise, you may not be able to
recognize dangerous situations until it is too
late and could cause an accident resulting in
personal or fatal injury to you or others.
i USA only:
This device
has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor is intended for use in an automotive
radar system only. Removal, tampering, or
altering of the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
i Canada only:
This device complies with RSS-210 of
Industry Canada. Operation is subject to
the following two conditions:
1. This device may not cause interference, and
2. this device must accept any interference received, including
interference that may cause undesired
operation of the device.
Removal, tampering, or altering of the
device will void any warranties, and is not
permitted. Do not tamper with, alter, or use
in any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Using the radar sensors, the PRE-SAFE ®
Brake detects obstacles that are in your
driving path for a sufficient period of time for
the system to recognize it. If you approach a
vehicle and the PRE-SAFE ®
Brake has
established that the distance to the vehicle
ahead at your current speed is so close that
the PRE-SAFE ®
Brake will not be capable of slowing the vehicle sufficiently, the system
will
initially
warn you visually and acoustically.
If you do not apply the brakes yourself or
maneuver around a sensed obstacle, the
vehicle will brake lightly automatically. The
PRE-SAFE ®
system (Y page 49) is activated
when the distance to the vehicle ahead at
your current speed is so close that the PRE-
SAFE ®
Brake will not be capable of slowing
the vehicle sufficiently. G
Warning!
The PRE-SAFE ®
Brake will only respond with
brake assistance if it has clearly detected an
object. Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
The PRE-SAFE ®
Brake

uses radar signals that
are not reflected well by narrow objects and
absorptive materials. For this reason the PRE-
SAFE ®
Brake will not react to persons,
animals, and approaching traffic or cross-
traffic.
The PRE-SAFE ®
Brake may not detect narrow
vehicles driving in front of you, such as
motorcycles and vehicles driving offset from
your vehicle center. G
Warning!
The PRE-SAFE ®
Brake brakes your vehicle
with a maximum of 13 ft/s 2
(4 m/s 2
). This
corresponds to about 40% of the maximum
deceleration ability of your vehicle. This
automatic braking is intended only to initiate
the braking

if the driver has not already done
so. The driver must apply the brakes in order
to prevent a collision.
The PRE-SAFE ®
Brake applies the brake pedal
automatically which results in the brake pedal
moving. Therefore keep driver’s foot area
clear at all times, including the area under the Driving safety systems

brake pedal. Objects stored in this area may
impair
pedal
movement which could interfere
with the braking ability of the PRE-SAFE ®
Brake.
Do not place your foot under the brake pedal
– your foot could become caught.
To maintain the proper distance to the vehicle
in front of you and thus prevent a rear-end
collision, you must apply the brakes yourself.
X Brake the vehicle immediately to avoid a
collision.
Under no circumstances should the driver
await the intermittent warning sound
before braking. Observe the following
warning note.
The intermittent

warning sound ceases and
the distance warning lamp · goes out
when the necessary distance to the vehicle
ahead is again established.
The PRE-SAFE ®
Brake
can react to stationary
obstacles such as standing or parked vehicles
at road speeds of up to approximately 40 mph
(70 km/h). G
Warning!
If you do not receive visual or acoustic
warning signals, the PRE-SAFE ®
Brake may
R not have recognized the collision risk
R have been deactivated
R be malfunctioning
Apply the

brakes yourself to avoid a collision.
The PRE-SAFE ®
Brake does not always clearly
interpret complex traffic situations. If a visual
and/or acoustic warning is issued in an
uncritical driving situation, or if the vehicle
brakes lightly, you can interrupt the PRE-
SAFE ®
Brake maneuver by pressing down all
the way on the accelerator pedal, using
kickdown, or releasing the brake pedal. The PRE-SAFE
®
Brake maneuver is
terminated immediately when
R you avoid the obstacle by evasive steering
R you drive less than 9 mph (15 km/h

)
R an obstacle can no longer be identified
ahead of you
R the system no longer senses the risk of a
collision
i The PRE-SAFE ®
Brake will remain passive
while DISTRONIC PLUS is switched on
(Y page 304).
After 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.
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 216). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada.
When you switch off the radar system, the
following functions are deactivated:
R PRE-SAFE ®
Brake
R BAS PLUS (Y page 57)
R DISTRONIC PLUS (Y page 304)
R Park Assist ( Y page 324)
R Blind Spot Assist (Y page 335)
R Advanced Parking Guidance ( Y page 327)
X Activating and deactivating: Activate or
deactivate the PRE-SAFE ®
Brake using the
instrument cluster control system
(Y page 213).
After the function has been activated, the
PRE-SAFE ®
Brake indicator Ä appears
in the instrument cluster. When the HOLD
function is switched on, the PRE-SAFE ®
Brake indicator Ä will not appear. 64

COMAND navigation (introduction)
Safety notes
G
Warning!
For safety reasons, only enter a destination
when the vehicle is stationary. When the
vehicle 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 (approximately
14 m) every second.
COMAND calculates the route to the
destination without taking account of the
following, for example:
R Traffic lights
R Stop and right-of-way signs
R Parking or stopping in prohibited areas
R Lane merging
R Other road and traffic rules and regulations
R Narrow bridges
COMAND may give incorrect navigation
commands if the data in the digital map does
not correspond with the actual road or traffic
situation. 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
regulations during your journey. Road and
traffic rules and regulations always have
priority over the navigation commands
generated by the system. G
Warning!
Navigation announcements are intended to
direct you

while driving without diverting your
attention from the road and driving.
Please always use navigation announcements
instead of consulting the map display for
directions. Consulting the symbols or map display for directions may cause you to divert
your
attention

from driving and increase your
risk of an accident. Map software
The digital maps generated by the map
software become outdated in the same way
as conventional road maps. Optimum route
guidance can only be provided by the
navigation system in conjunction with the
latest map software. Information about new
map software versions can be obtained from
an authorized Mercedes-Benz Center.
