Vehicle equipment
i This Operator’s Manual describes all
features, standard or optional, potentially
available for your vehicle at the time of
purchase. Please be aware that your
vehicle might not be equipped with all
features described in this manual. Occupant safety
Introduction
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint systems are:
R Seat belts
R Child restraints
R Lower Anchors and Tethers for CHildren
(LATCH) also known as ISOFIX
Additional protection
potential is provided by:
R Supplemental Restraint System (SRS) with
- Air bags
- Air bag control unit (with crash sensors)
- Emergency Tensioning Device (ETD) for
seat belts
- Seat belt force limiter
R Preventive occupant safety (PRE-SAFE
®
)
R Air bag system components with
-Front passenger front air bag off
indicator lamp
- Front passenger seat with Occupant
Classification System (OCS)
Although the systems are independent, their
protective functions

work in conjunction with
each other. G
Warning!
Modifications to or work improperly
conducted on restraint system components or their wiring, as well as tampering with
interconnected electronic systems, can lead
to
the

restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See “Children in the vehicle”
(Y page 51) for information on
R infants and children traveling with you in
the vehicle
R restraint systems for infants and children SRS indicator lamp
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of system malfunctions.
The SRS indicator lamp 6 in the
instrument cluster comes on when the
ignition is switched on. It goes out no later
than a

few seconds after the engine has been
started.
The SRS components are in operational
readiness when the SRS indicator lamp
6 is not lit while the engine is running. G
Warning!
The SRS self-check has detected a
malfunction when the SRS indicator lamp
6
R does not come on at all
R fails to go out after approximately
4 seconds after the engine was started
R comes on after the engine was started or
while driving 36

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

menu. Activating/deactivating air
conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
i
Condensation may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction. G
Warning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.

If the air conditioning cannot be activated
again, this indicates that the air
conditioning is losing refrigerant. The
compressor has turned off.
Have the air conditioning checked at the
nearest authorized Mercedes-Benz Center.
Selecting Mono mode Mono is used to adjust the climate zones for
the entire vehicle at the same time. When the
Mono function is switched on and you change
the climate on the driver’s side, these
changes will be carried out in the same
manner for all climate zones.196

3 Starting position
When you switch on the ignition, all lamps in
the instrument cluster come on. The high-
beam headlamp indicator lamp and turn
signal indicator lamps will only come on if activated. If a lamp in the instrument cluster
fails to come on when the ignition is switched
on, have it checked and replaced if necessary.
If a lamp in the instrument cluster remains on
after starting the engine or comes on while
driving, refer to “Lamps in instrument cluster”
(Y page 450).
X
Always remove the SmartKey from the
starter switch when the engine is not in
operation.
This will help to prevent accelerated vehicle
battery discharge or a completely
discharged vehicle battery.
If the SmartKey cannot be turned in the
starter switch, the vehicle battery may not be
sufficiently charged.
X Check the vehicle battery and charge it if
necessary ( Y page 471).
or
X Get a jump start (Y page 471).
i If the SmartKey does not belong to the
vehicle, the SmartKey can be turned in the
starter switch. However, the ignition does
not switch on and the engine does not start. KEYLESS-GO

Observe Safety notes, see page 51.
Vehicles equipped with the KEYLESS-GO
feature are supplied with a SmartKey with
integrated KEYLESS-GO function and a
removable KEYLESS-GO start/stop button.
