warning MERCEDES-BENZ CLS 2010 Owners Manual

The Distronic regulates only the distance
between your vehicle and those directly
ahead of it, but does not register stationary
objects in the road, e.g.:
R
a stopped vehicle in a traffic jam
R a disabled vehicle
R an oncoming vehicle
The driver must always be alert, observe all
traffic and intercede as required by means of
steering or braking the vehicle. G
Warning!
The Distronic should not be used in snowy or
icy road conditions.
The most likely cause for a malfunctioning
system is a dirty Distronic system sensor
cover (located in the hood grille), especially
at times of snow and ice or heavy rain.
In such a case, the Distronic will switch off,
and the message DISTRONIC Currently
Unavailable – See Operator’s Manual
appears in the multifunction display.
For cleaning and care of the Distronic system
sensor cover, see (Y page 219).
i If the message DISTRONIC Currently
Unavailable – See Operator’s
Manual disappears during driving and the
last set speed flashes for approximately
5 seconds, the dirt (e.g. slush) has
dissolved; the Distronic works again.
Turns and bends In turns or bends, the Distronic may not
detect a moving vehicle in front, or it may detect one too soon. This may cause your
vehicle to brake late or unexpectedly.
Offset driving
A vehicle traveling in your lane but offset from
your direct line of travel may not be detected
by the Distronic. There will be insufficient
distance to the preceding vehicle.
Lane changing
The Distronic has not yet detected the vehicle
changing lanes. There will be insufficient
distance to the lane-changing vehicle.

Because of their narrow profile, the vehicles
traveling near the outer edges of the lane
have not yet been detected by the Distronic.
There will be insufficient distance to the
preceding vehicles.
Distance warning function
When the Distronic is deactivated, this
function will continue to warn you when
recognizing a stationary obstacle or a slower
vehicle moving in your vehicle’s path and the
danger of a collision exists:
R
The distance warning lamp · in the
instrument cluster comes on.
R An intermittent warning will sound if
necessary.
If these warnings are issued, you must apply
the brakes to maintain a safe distance and
avoid a collision with the preceding vehicle.
When depressing the brake pedal, the
warning sound ceases. The warning sound
will also cease when the distance to the
preceding vehicle is sufficient again without
applying the brakes. In this case, the distance
warning lamp · will also go out. G
Warning!
If the distance warning lamp · in the
instrument cluster comes on while driving
and/or an intermittent warning sounds,
immediate attention on the part of the driver
is required. As required by the traffic
situation, apply the brakes and navigate
around a possible obstacle. However, do not
drive by relying on the distance warning
function, as this will result in an emergency
braking application. This will not always
enable you to avoid a collision, especially
when traveling on varying road surface
conditions and with varying driver reaction.
Complex driving situations are not always
fully recognized by the distance warning
function. This could result in wrong or missing
distance warnings. X
Activating/deactivating: Press

When the distance warning function is
activated, indicator lamp ; in switch :
comes on. A loudspeaker symbol appears
in the multifunction display ( Y page 132). Airmatic DC (Dual Control)
Introduction The AIRMATIC DC lets you select the chassis
and suspension setup. The chassis and
suspension setup adjusts the damping
behavior and the ride height for your vehicle.
The AIRMATIC DC consists of two
components. The Adaptive Damping System
(ADS) (
Y page 137) and the vehicle level
control ( Y page 138).

Warning!
If you have selected the Comfort suspension
tuning, the vehicle lowers slightly when you
lock it within approximately 60 seconds after
turning off the engine. To avoid personal
injury, make sure nobody is in the vicinity of
the wheel housing or under the vehicle when
you turn off the engine.
! When parking, make sure there is
sufficient clearance under the vehicle for it to lower without making contact with the
road curb for example. Otherwise, the
vehicle could be damaged.
Vehicle level control G
Warning!
To help avoid personal injury, keep hands and
feet away from wheel housing area, and stay
away from under the vehicle when lowering
the vehicle chassis.
Your vehicle automatically adjusts its ride
height to increase vehicle safety and to
reduce fuel consumption.
You can choose between normal or raised
level.
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed. At a speed
exceeding approximately 68 mph
(110 km/h) with normal level set or
exceeding 75 mph (120 km/h) with raised
level set, the ride height is reduced
automatically. With decreasing speed, the
ride height is again raised to the normal level.
i These height adjustments are so small
that you may not notice any change.
Select the raised level only when required by
current driving conditions. Otherwise, the
handling may be impaired and the fuel
consumption may increase. 138

The Parktronic system deactivates at speeds
above approximately 11 mph (18 km/h). At
lower speeds, the Parktronic system
activates again.
The Parktronic system also deactivates when
you shift the automatic transmission into
park position P or engage the parking brake.
The Parktronic system monitors the
surroundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper. Example illustration, sensors in the front bumper
To function properly, sensors
: must be free
of dirt, ice, snow and slush. Clean
sensors : regularly. Be careful not to
scratch or damage sensors :, see “Cleaning
the driving systems sensors” (Y page 219). G
Warning!
The Parktronic is a supplemental system. It is
not intended to, nor does it replace, the need
for extreme care. The responsibility during
parking and other critical maneuvers always
remains with the driver. G
Warning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured. !
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts,
elevated crossbars or road curbs). Such
objects may not be detected by the system
and can damage the vehicle.
During parking maneuvers, pay special
attention to objects located above or below
the height of the sensors (e.g. street curbs,
painted posts, or trailer hitches etc.). The
Parktronic system will not detect such
objects at close range and damage to your
vehicle or the object may result.
! Ultrasonic signals from outside sources
(e.g. truck air brakes, car wash, or
jackhammers) may impair the operation of
the Parktronic system.

Notes on climate control system
The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows and the tilt/sliding
sunroof closed.
Nearly

all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system. G
Warning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its

scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
The air conditioning will not engage (no
cooling) if the A/C mode (Y page 146) is
deactivated. G
Warning!
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
X Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing objects on
the air flow-through exhaust slots below the
rear window.
i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer
opening feature” ( Y page 96). The climate
control will then adjust the interior
temperature to the set value much faster. Deactivating the climate control
system
G
