2007 MERCEDES-BENZ CL500 Pre safe

75 Safety and Security
Driving safety systems
To maintain the proper distance to the ve-
hicle in front of you and thus prevent a
rear-end collision, you must apply the
brakes yourself.
Immediately brake the vehicle to avoid
a collision.
Under no circumstances should the
driver await the intermittent warning
sound before braking. See the follow-
ing warning note.
The intermittent warning sound ceases
and the distance warning lampl
goes out when the necessary distance
to the vehicle ahead is again
established.
Warning!G
PRE-SAFE® Brake brakes your vehicle with a
maximum of 13 ft/s2 (4 m/s2). This corre-
sponds to about 40% of the maximum decel-
eration ability of your vehicle. This
automatic braking is intended only to ini-
tiate the braking if the driver has not already
done so. The driver must apply the brakes in
order to prevent a collision.
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 un-
der the 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.
Warning!G
An intermittent warning sounds and the dis-
tance warning lampl in the instrument
cluster is illuminated if PRE-SAFE
® Brake
calculates that the distance to the vehicle
ahead and your vehicle’s current speed indi-
cate that PRE-SAFE
® Brake will not be capa-
ble of slowing the vehicle sufficiently to
maintain the preset following distance,
which creates a danger of a collision.
Immediately brake your vehicle to increase
the distance between your vehicle and the
vehicle driving in front of you. The warning
sound is intended as a final caution that you
have not interceded with your own braking
inputs to avoid a potentially dangerous situ-
ation. Do not wait for the operation of the
warning signal to intercede with your own
braking, as that will result in potentially dan-
gerous emergency braking which will not al-
ways result in an impact being avoided.
Tailgating increases the risk of an accident.

76 Safety and Security
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 (
page 411).

COMAND navigation
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.
