57 Safety and Security
Occupant safety
Side impact airbags
The side impact airbags are deployed:

on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front airbags
The side impact airbags will not deploy in
impacts which do not exceed the system’s
deployment threshold.
The passenger side impact airbag will only
be deployed if the system senses that the
passenger seat is occupied.
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 steering lock to
position2 and the driver’s 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.
Information on fastening seat belts is
found in the “Getting started” section
(
page 37).
!Do not place objects heavier than
20 lbs (9 kg) on the passenger seat.
This could cause the front or side im-
pact airbag on the passenger side to
deploy in a crash which exceeds the
system's deployment threshold.

traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 60).

67 Safety and Security
Driving safety systems
Continuous steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and ability to steer
the vehicle.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure. The
pulsating brake pedal can be an indication
of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.ABS control
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.
More information can be found in the
“Practical hints” section (
page 196).
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 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 systemsBAS
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.
More information can be found in the
“Practical hints” section.
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 lamp
v
in the speed-
ometer dial flashes when the ESP is en-
gaged.
The warning lamp
v
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.

Immobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
Activating

Removing the key from the steering
lock activates the immobilizer.
Deactivating


Inserting the key in the steering lock
deactivates the immobilizer.
Anti-theft alarm system
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens

a door


the trunk


the hood.
The alarm system will also be triggered
when


someone attempts to raise the vehicle.Arming the alarm system
The alarm system is armed within approxi-
mately 10 seconds after locking the vehi-
cle. The indicator lamp in the switch for the
tow-away alarm (
page 72) will then
blink.
Disarming the alarm system
The alarm system is disarmed when you
unlock your vehicle with the remote con-
trol.
Canceling the alarm
To cancel the alarm:

Insert the key in the steering lock.

iIn case the engine cannot be started
(yet the vehicle’s battery is charged),
the system is not operational. Contact
an authorized Mercedes-Benz Center
or call 1-800-FOR-MERCedes (in the
USA), or 1-800-387-0100 (in Canada).
iIf the alarm stays on for more than
20 seconds, an emergency call is initi-
ated automatically by the Tele Aid sys-
tem provided Tele Aid service was
subscribed to and properly activated,
and that necessary cellular service and
GPS coverage are available.

To brighten illumination
Turn knob3 (

The instrument lamps will brighten.
To dim illumination

Turn knob3 counterclockwise.
The instrument lamps will dim.
Display illumination

Press knob3.
With key removed or in steering lock
position0 or1 (
page 29), the display
is illuminated for a short time.
Coolant temperature gauge
Under normal driving conditions, the cool-
ant temperature may rise to 248°F
(120°C). The coolant temperature may
climb to the red marking:

at high outside temperatures


during stop-and-go city traffic


when driving on hilly terrain
The engine should not be operated with
the coolant temperature in the red zone.
Doing so may cause serious engine dam-
age which is not covered by the
Mercedes-Benz Limited Warranty.

within the red marking.
Warning!
G
Driving when your engine is badly overheat-
ed can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down.
iAvoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.

90 Controls in detailInstrument clusterOutside temperature indicator
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.

ment cluster (

Pull out the right knob5 in the instru-
ment cluster and turn it clockwise.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
iTo adjust the time by a single hour or a
few minutes, turn knob5 just a few de-
grees in the direction indicated for
hours or minutes.
