When the OCS senses that the front-
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
42 indicator lamp will illuminate
for approximately 6 seconds when the engine
is started and then, depending on occupant
weight sensor readings from the front-
passenger seat, remain illuminated or go out.
With the 42 indicator lamp
illuminated, the front-passenger front air bag
is deactivated. With the 42
indicator lamp out, the front-passenger front
air bag is activated.
When the OCS senses that the front-
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 42 indicator lamp
will illuminate 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 42 indicator lamp is
illuminated, the front-passenger front air bag
is deactivated and will not be deployed.
If the 42 indicator lamp is not
illuminated, the front-passenger front air bag
is activated and will be deployed:
R in the event of certain frontal impacts
R if impact exceeds a preset deployment
threshold
R independently of the side impact air bags
If the front-passenger front air bag is
deployed, the rate of inflation will be
influenced by:
R the rate of vehicle deceleration as assessed
by the air bag control unit
R the front passenger's weight category as
identified by OCS
For further information, see the section
regarding air bag display messages
( Y page 386).GWarning
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child.
The infant or child restraint system must be
properly secured with the vehicle's seat belt,
the seat belt and Top Tether strap, or lower
anchors and Top Tether strap, fully in
accordance with the child seat
manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriate sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front-
passenger seat:
R Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front-passenger seat.
R A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place a child
in a rear-facing child restraint in the front-
passenger seat. We therefore strongly

52Occupant safetySafety
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user's safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.GWarning!
HYBRID vehicles: It is imperative that you read
the HYBRID Supplemental Operating
Instructions included in your vehicle literature
portfolio. You may otherwise not receive all
necessary safety information and warning for
the operation of your vehicle.
i In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible.
ABS (Anti-lock Braking System)
Important safety notes
GWarning
Observe "Important safety notes"
( Y page 66).
GWarning
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS works from a speed of about
5 mph (8 km/h) upwards, regardless of road-
surface conditions. ABS works on slippery
surfaces, even when you only brake gently.
The ! warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Braking
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking
situation is over.XTo make a full brake application:
depress the brake pedal with full force.GWarning
If the ABS malfunctions, other driving systems
such as the BAS or the ESP ®
are also switched
off. Observe indicator and warning lamps that
may come on as well as messages in the
multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
BAS (Brake Assist System)
GWarning
Observe "Important safety notes"
( Y page 66).
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.Driving safety systems67SafetyZ
Important information about using
KEYLESS-GO
RYou can use the KEYLESS-GO key as a
conventional SmartKey.
RYou can combine KEYLESS-GO functions
with those of a conventional SmartKey, e.g.
you can open the vehicle with KEYLESS-GO
and close it with the & button.
RAlways carry your KEYLESS-GO key on your
person.
RNever store the KEYLESS-GO key together
with:
-electronic devices, such as a mobile
phone or other SmartKey
-metal objects, such as coins or metal foil
Doing so may impair the function of
KEYLESS-GO.
RTo open or close the vehicle, the KEYLESS-
GO key should not be more than 3 ft (1 m)
from the door or trunk.
RIf the vehicle is parked for more than
72 hours, the KEYLESS-GO function is
deactivated. Pull an outer door handle and
switch on the ignition to reactivate the
KEYLESS-GO function.
RIf the KEYLESS-GO key is removed from the
vehicle, the system may not be able to
recognize the SmartKey anymore. The
vehicle can then no longer be locked or
started with KEYLESS-GO.
RIf the KEYLESS-GO key has been removed
from the vehicle, e.g. when another vehicle
occupant with a KEYLESS-GO key leaves
the vehicle:
-when the Start/Stop button is pressed,
or when trying to lock the vehicle using
the locking button on the outside door
handle, the Key Not Detected message
appears in the multifunction display.
-when the engine is running, the red Key
Not Detected message appears in the
multifunction display as you pull away.
Look for the KEYLESS-GO key and place
it somewhere else in the vehicle. Place
the KEYLESS-GO key on the front-
passenger seat, for example, or in your
shirt pocket.
RIf you have switched on the engine with the
Start/Stop button, you can switch it off
again by:
-pressing the Start/Stop button
-inserting the KEYLESS-GO key into the
ignition lock while the vehicle is at a
standstill and the automatic
transmission is in park position P.
RYou may inadvertently unlock the vehicle if
the KEYLESS-GO key is less than 3 ft (1 m)
from the vehicle and:
-an exterior door handle is hit by a jet of
water, or
-you clean an exterior door handle
RPlease note that any vehicle occupant can
start the engine when there is a KEYLESS-
GO key in the vehicle.
Scenario 1: There is a KEYLESS-GO key in
the vehicle and a second one outside the
vehicle. If you leave the KEYLESS-GO key
in the vehicle when you leave and lock the
vehicle, no message appears in the
multifunction display.
Scenario 2: There is a KEYLESS-GO key in
the vehicle, but none outside the vehicle. If
you get out of the vehicle and attempt to
lock it, the Key Detected In Vehicle
message appears in the multifunction
display. The vehicle is not then locked.
When starting the engine and whilst driving,
KEYLESS-GO also checks whether a valid
SmartKey is in the vehicle by periodically
establishing radio contact.
