2004 MERCEDES-BENZ SLK320 warning light

Occupant safety
The7indicator lamp 1 located in the
center console will be illuminated, except
with the key removed or in the steering
lock position0.Self-test BabySmart
TM without special
child seat installed
After turning the key in the steering lock to
position1 or2, the7indicator lamp
located in the center console lights up for
approx. six seconds and then goes out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized
Mercedes-Benz Center before seating any
child on the passenger seat.
More information can be found in the
“Practical hints” section (page 211).
iThe system does not deactivate the
side impact airbag and the emergency
tensioning device.
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.

64 Safety and SecurityOccupant safetyWarning!
G
When using a BabySmart
TM compatible
child seat on the passenger seat, the front
passenger airbag will not deploy only if
the7 indicator lamp remains illuminat-
ed.
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the passenger seat until the system has
been repaired.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
passenger seat. Signals from such devices
may interfere with the BabySmart
TM system.
Such signal interference may cause
the7 indicator lamp not to come on dur-
ing self-test or be continuously lit, indicating
that the system is not functioning.

ESP (E

ABS
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 ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure.
The - malfunction indicator lamp in the
instrument cluster (
page 20) lights up
when you turn the key in the steering lock
to position2. It goes out when the engine
is running.
iIn winter operation, the maximum ef-
fectiveness of the ABS and ESP is only
achieved with winter tires (M + S tires),
or snow chains as required.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS and ESP cannot reduce this
risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.

67 Safety and Security
Driving safety systems
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
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 indica-
tion of hazardous road conditions and
functions as a reminder to take extra care
while driving.Emergency brake maneuver

Keep continuous full pressure on the
brake pedal.
For more information, see “Practical hints”
(
page 199).
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing braking distance. Apply con-
tinuous 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.
The malfunction indicator lamp for the ESP
is combined with that of the BAS.
The¿ malfunction indicator lamp in
the instrument cluster lights up when you
turn the key in the steering lock to
position2. It goes out when the engine is
running.
For more information, see “Practical hints”
(page 199).
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction. The
ABS cannot prevent accidents, including
those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ABS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.

68 Safety and SecurityDriving safety systems
ESP
The Electronic Stability Program (ESP)
monitors the vehicle's traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP works to
stabilize the vehicle. The ESP is especially
useful while driving off and on wet or slip-
pery road surfaces.
The ESP warning lampv in the speed-
ometer dial flashes when the ESP is en-
gaged.
The warning lampv in the speedome-
ter dial lights up when you turn the key in
the steering lock to position2. It goes out
when the engine is running.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that af-
forded by the condition of the vehicle brakes
and tires or the traction. The BAS cannot
prevent accidents, including those resulting
from excessive speed in turns, following an-
other vehicle too closely, or hydroplaning.
Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of a BAS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
Warning!
G
Never switch off the ESP when you see the
ESP warning lampv flashing in the
speedometer dial. In this case, proceed as
follows:

While driving off, apply as little throttle
as possible


While driving, ease up on the accelera-
tor


Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.

sole.

Press upper half1 of the ESP switch
until the ESP warning lampv in the
speedometer lights up.
The ESP is deactivated.
If one or more drive wheels are spinning,
the ESP warning lampv in the speed-
ometer flashes, regardless of the speed.
Traction control brakes a spinning wheel
even when the ESP is deactivated.The ESP always operates when you are
braking, even when it has been deactivat-
ed.Switching on the ESP

Press lower half2 of the ESP switch
until the ESP warning lampv in the
speedometer goes out.
You are now again in normal driving
mode.
!Avoid spinning of a drive wheel for an
extended period with the ESP switched
off. This may cause serious damage to
the drivetrain which is not covered by
the Mercedes-Benz Limited Warranty.Warning!
G
When the ESP warning lampv is
illuminated continuously, the ESP is
switched off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP.
