Driving
The combination switch resets automati-
cally after major steering wheel move-
ments.Windshield wipers
The combination switch is located on the
left of the steering column.

Switch on the ignition (page 40).
iTo signal minor directional changes such as
changing lanes, press combination switch only
to point of resistance and release.
The corresponding turn signals will flash three
times.
!Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions,
always operate the windshield wipers with
windshield washer fluid (
page 60).
!If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off imme-
diately.

For safety reasons, stop the vehicle in a safe
location and

remove the SmartKey from the starter
switch
or

turn off the engine by pressing the
KEYLESS-GO* start/stop button and
open the driver’s door (with the driver’s
door open, the starter switch is in
position 0, same as with the SmartKey
removed from the starter switch)
before attempting to remove any blockage.

Remove blockage.

Turn the windshield wipers on again.

71 Safety and Security
Occupant safety

Occupants, especially children, should
never lean their heads in the area of the
door where the head-thorax air bag in-
flates. This could result in serious inju-
ries or death should the air bag be
deployed. Always sit as upright as possi-
ble, properly use the seat belts and an
appropriately sized infant restraint,
toddler restraint, or booster seat
recommended for the size and weight of
the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this
Operator’s Manual.Warning!G
There is a possibility of a head-thorax air bag
related injury if occupants, especially chil-
dren, are not properly seated or restrained
when next to a head-thorax air bag which
needs to deploy rapidly in a side impact in
order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax air bag inflates. This could
result in serious injuries or death should
the head-thorax air bag be deployed.
(2) Always sit as upright as possible, prop-
erly use the seat belts and for children
12 years old or under, use an appropri-
ately sized infant restraint, toddler
restraint, or booster seat recommended
for the size and weight of the child.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
passenger seat occupants to have the pas-
senger side head-thorax air bag deactivated,
then deactivation can be accomplished
upon your written election to do so at an
authorized Mercedes-Benz Center at an
additional cost.
Please contact your local authorized
Mercedes-Benz Center or call the Customer
Assistance Center (in the USA) at
1-800-FOR-MERCedes (1-800-367-6372),
or Customer Service (in Canada) at
1-800-387-0100 for details.
iAir bags are designed to activate only in cer-
tain frontal impacts (front air bags, driver-side
knee bag) and side impacts (head-thorax air
bags) which exceed preset thresholds. Only
during these events, will they provide their
supplemental protection.
The driver and passenger should always wear
their seat belts. Otherwise it is not possible for
the air bags to provide their supplemental
protection.

73 Safety and Security
Occupant safety
When you sell your vehicle, we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.Front air bags
1Driver air bag
2Passenger air bag
3Knee bag
Driver and passenger air bags and driver’s
side knee bag are deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the head-thorax air
bagsThe air bags will not deploy in impacts
which do not exceed the system’s
deployment thresholds. You will then be
protected by the fastened seat belts.

In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Center.

For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be
followed. These instructions are
available from any authorized
Mercedes-Benz Center.

Given the considerable deployment
speed, required inflation volume, and
the textile structure of the air bags,
there is the possibility of abrasions or
other, potentially more serious injuries
resulting from air bag deployment.
iThe front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of relevant vehicle decelera-
tion as assessed by the air bag control unit.
On the passenger side, the front air bag deploy-
ment is additionally influenced by the passen-
ger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 74).
The lighter the passenger side occupant, the
higher the vehicle deceleration rate required for
the second stage inflation of the air bag.

74 Safety and Security
Occupant safety
The passenger air bag will only be de-
ployed if:

the system, based on OCS weight
sensor readings, senses that the
passenger seat is occupied

the5/ indicator lamp in the
center console is not lit (
page 78)

the impact exceeds a preset deploy-
ment threshold
Knee bag
The knee bag is located on the driver’s side
lower instrument panel. It is designed to
operate together with the driver front air
bag in certain frontal impacts exceeding a
preset threshold. The knee bag operates
best in conjunction with a properly posi-
tioned and fastened seat belt.Head-thorax air bags
1Head-thorax air bag
The head-thorax air bags are deployed:

in side impacts exceeding a preset
deployment threshold

on the impacted side of the vehicle

independently of the front air bags
The head-thorax air bags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
Occupant Classification System
The O
ccupant Classification System (OCS)
automatically turns the passenger front air
bag on or off based on the classified occu-
pant weight category determined by
weight sensor readings from the
passenger seat.
Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by
leaning on armrests), the OCS may not be
able to properly approximate the
occupant’s weight category.
iThe system does not deactivate the
head-thorax air bag and the emergency tension-
ing device.

76 Safety and Security
Occupant safety
When the OCS senses that the passenger
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
5/indicator lamp will illuminate for
approximately 6 seconds when the engine is
started and then, depending on occupant
weight sensor readings from the seat, re-
main illuminated or go out. With the
5/ indicator lamp illuminated, the
passenger front air bag is deactivated. With
the 5/ indicator lamp out, the pas-
senger front air bag is activated.
When the OCS senses that the passenger
seat occupant is classified as an adult or
someone larger than a small individual, the
5/ indicator lamp will illuminate for
approximately 6 seconds when the engine is
started and then go out, indicating that the
passenger front air bag is activated.If the 5/ indicator lamp is
illuminated, the passenger front air bag is
deactivated and will not be deployed.
If the 5/ indicator lamp is not
illuminated, the passenger front air bag is
activated and will be deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the head-thorax air
bags
If the passenger front air bag is deployed,
the rate of inflation will be influenced by:

the rate of relevant vehicle deceleration
as assessed by the air bag control unit

the passenger’s weight category as
identified by the Occupant Classification
System (OCS)
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant or child restraint recommended
for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt fully in
accordance with the child seat manufactur-
er’s instructions.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information:

Your vehicle is equipped with air bag
technology designed to turn off the pas-
senger front air bag in your vehicle when
the system senses the weight of a typi-
cal 12-month-old child or less along with
the weight of a standard appropriate
child restraint on the passenger seat.
