51 Safety and Security
Occupant safety
Both driver and the front passenger should
always use the 59indicator
lamp as an indication of whether or not the
front passenger is properly positioned.Warning!
G
If the 59indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
59indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display mes-
sages (
page 562).
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 59indicator
lamp will illuminate when the engine is start-
ed and remain illuminated, indicating that
the front passenger front air bag is deacti-
vated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
59indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 59indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on
occupant weight sensor readings from
the seat, remain illuminated or go out. With
the 59indicator lamp illumi-
nated, the front passenger front air bag is
deactivated. With the 59 indi-
cator lamp out, the front passenger front air
bag is activated.
When the OCS senses that the front passen-
ger seat occupant is classified as an adult or
someone larger than a small individual, the
59indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the front passenger front air bag is
activated.
If the 59indicator lamp is illu-
minated, the front passenger front air bag is
deactivated and will not be deployed.
If the 59indicator lamp is not
illuminated, the front passenger front air
bag is activated and will be deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold

ETS
The Electronic Traction System is a compo-
nent of ESP
®.
The Electronic Traction System (ETS) im-
proves the vehicle’s ability to utilize avail-
able traction, especially under slippery road conditions. The brakes are applied to
the spinning wheel and power is trans-
ferred to the wheel(s) with traction.
The ESP
® warning lampvin the instru-
ment cluster starts to flash at any vehicle
speed, as soon as a tire loses traction and
the wheel begins to spin.
When you switch off the ESP
®, the ETS is
still enabled.Switching off the ESP
®
To improve the vehicle’s traction, turn off
the ESP
® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:
when driving with snow chains
in deep snow
in sand or gravel
i
The ESP
® will only function properly if you
use wheels of the recommended tire size
(
page 655).
!
Because of the ESP’s
® automatic operation,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO start/stop button* in position0
or1) when
the parking brake is being tested on a brake
test dynamometer
the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
Warning!
G
If you are driving too fast, the Electronic
Traction System cannot reduce the risk of
an accident.
The ETS cannot prevent the natural laws of
physics from acting on the vehicle.i
If the yellow ESP
® warning lampv
comes on while driving, the ETS is being
switched off temporarily to prevent overheating
of the drive wheel brakes. In addition, the mes-
sage “ESP Currently unavailable See Oper. Man-
ual” appears in the multifunction display.
Warning!
G
The ESP
® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
!
Turn the ESP
® on immediately if the afore-
mentioned circumstances do not apply anymore.
i
DISTRONIC Plus* cannot be activated when
the ESP
® has been switched off.
