independently of the side impact air-
bags
The airbags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.
The front passenger airbag will only be de-
ployed if:


the front passenger seat is occupied


the PASSENGER AIRBAG OFF indicator
lamp in the center console is not lit

airbags
1Side impact airbags
2Window curtain airbag
The side impact airbags and window cur-
tain airbags are deployed:


on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front airbags
The front passenger side airbag will only
deploy if the system senses that the front
passenger seat is occupied.The side impact airbags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
Seat belts
The seat belt nonusage warning lamp <
in the instrument cluster lights up and a
warning sounds for a short time when you
turn the key in the starter switch to
position2 or press the KEYLESS-GO* (if so
equipped) start/stop button twice and the
drivers seat belt is not fastened.
After starting the engine the seat belt non-
usage warning lamp blinks for a brief peri-
od to remind the driver and passengers to
fasten the seat belts.
The use of seat belts and infant and child
restraint systems is required by law in
most states and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened whenever the vehicle is in motion.
!Do not place objects heavier than 20
lbs (9 kg) on the front passenger seat.
This could cause the front or side im-
pact airbag on the front passenger side
to deploy in a crash which exceeds the
system&#39;s deployment threshold.

the following driving safety systems:

ABS
The 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.
If the ABS activates during braking, the
ESP warning lamp v in the instrument
cluster dial flashes. Because of the SBC
brake system, you will not feel any pulsa-
tion in the brake pedal.
iIn winter operation, the maximum ef-
fectiveness of the ABS and the 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, ESP and SBC 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.
ProCarManuals.com

74 Safety and SecurityDriving safety systemsContinuos steady brake pedal pressure
yields the advantagesprovided by the ABS,
namely braking power and ability to steer
the vehicle.
The - warning lamp in the instrument
cluster lights up when you turn the key in
the starter switch to position2 or press
the KEYLESS-GO* (if so equipped)
start/stop button twice. It goes out when
the engine is running.
More information can be found in the
&#34;Practical hints&#34; section (
page 289).
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 the braking distance. Apply
continuous 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.
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
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 aquaplaning. 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.

The switch is located on the center con-
sole.

Press button1.
The ESP warning lamp v, located in
the instrument cluster comes on.
Some functions of the ESP remain active,
even when the button is in the OFF posi-
tion.
The ESP warning lamp v in the instru-
ment cluster starts to flash at any speed as
soon as the tires lose traction. Switching on the ESP

Press button1.
The ESP warning lamp v in the in-
strument cluster goes out. You are now
again in normal driving mode.
The SBC brake system
The SBC brake system combines a hydrau-
lic brake circuit with electronically con-
trolled brake servo assistance. You have
increased braking safety and improved
braking comfort.
!Avoid spinning of one drive wheel for
an extended period with the ESP
switched off. This may cause serious
damage to the drive train which is not
covered by the Mercedes-Benz Limited
Warranty.Warning!
G
When the ESP warning lamp
v
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.
Warning!
G
Never ignore a brake malfunction indicated
in the speedometer display, for example by
the
;
(USA only) or

(Canada only)
indicator lamp. Refer to the &#34;Practical hints&#34;
section (
page 291). Also read and ob-
serve the messages in the instrument clus-
ter display (page 295).

78 Safety and SecurityDriving safety systems
The SBC brake system is automatically ac-
tivated when you:

unlock the vehicle with the key or the
KEYLESS-GO*


open the driver’s or passenger door


turn the key in the starter switch to
position1


in vehicles with KEYLESS-GO*, press
start/stop button on selector lever
once


depress the brake pedal


release the parking brake
Warning!
G
The SBC brake system requires electrical
power to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its
limp-home (emergency operation) mode. In
such a case, the red brake warning lamp
(page 291) and warning messages in the
instrument cluster (
page 305) light up
while driving. To brake, the driver must then
apply significantly greater brake pedal pres-
sure and depress the pedal much further to
obtain the expected braking effect. If neces-
sary, apply full pressure to the brake pedal.
Brakes are only applied to the front wheels.
Stopping distance is increased!
If there is a malfunction in the SBC brake
system, we recommend that the vehicle be
transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment. A tow bar must be used if cir-
cumstances do not permit the use of the
recommended towing methods and the ve-
hicle requires towing with all four wheels on
the ground. Towing the vehicle with all four
wheels on the ground is only permissible
for distances up to 30 miles (50 km) and at
a speed not to exceed 30 mph (50 km/h).
For more information, refer to &#34;Towing the
vehicle&#34; (
