i After an airb ag has been deployed, have
th ev ehicle towed to th eneares tqualified
specialist workshop, eve nifyour vehicle is
ready to drive.
Front air bags Driver'
sair bag 001Adeploys in front of the
steerin gwheel; front-passenger front air
bag 0010deploys in front of and above the glove
box.
The front air bags increase protection for the
driver's and front passenger's head and
chest.
They are deployed:
R at the start of an accident with ahigh rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R independently of other air bags in the
vehicle
The release time of the front air bags is
dependent upon the use of the seat belt.
If the vehicle rolls over, the front air bags are
generally not deployed.
Your vehicle has adaptive, two-stage front air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
event of acollision. In the first deployment
stage, the front air bag is filled with part of the
total available propellant gas, thereby reducing the risk of injury. If the air bag
control unit recognizes within
afew
milliseconds that the vehicle is being braked
or accelerated faster than originally
predicted, the front air bag is filled with the
maximum amount of propellant gas available.
The deployment of the front-passenger front
air bag is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) (Y page 47).
The lighter the passenger-side occupant ,the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for
second stage inflation of the front-passenger
front air bag. In the second stage, the front
air bags are inflated with the maximum
amount of propellant gas available.
The front air bags are not deployed in
situations where alow impact severity is
predicted. You will then be protected by the
fastened seat belt.
The front-passenger front air bag will only
deploy if:
R the system, based on the OCS weight
sensor readings, detect sthat the front-
passenger seat is occupied
R the PASSENGER air bag OFF indicator lamp
on the center console is not lit
(Y page 47)
R the air bag control unit predicts ahigh
impact severity

brake pads. This can result in
asignificantly
longer brakin gdistance.
R Brak eoccasionally to remov eany possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginning and end of ajourney.
R Maintain agreater distance to the vehicle
ahead.
Servicing the brakes !
If the red brake warning lamp lights up in
the instrument cluster and you hear a
warning ton ewhile the engin eisrunning,
the brake fluid level may be too low.
Observ eadditional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked
immediately. This work should be carried
out at aqualified specialist workshop.
! Afunction or performanc etest should
only be carried out on a2-axle
dynamometer. If yo uareplanning to have
the vehicl eteste dons uchad ynamometer,
contact an authorize dMercedes-Benz
Center to obtai nfurthe rinformatio nfirst.
Otherwise, yo ucould damage the drive
trai nort he brake system.
! As the ESP ®
system operates
automatically, the engine and the ignition
must be switched off (the SmartKe ymust
be in position 0or 1in the ignition lock) if:
R the electri cparking brak eistested on a
brake dynamometer (for amaximum of
ten seconds)
R the vehicle is towed with the front axle
raised.
Braking triggered automaticallybyE SP®
may seriouslyd amage the brake system.
All checks and maintenance work on the
brake system must be carried out at a qualified specialist workshop. Consult a
qualified specialist workshop to arrange this.
Have brake pads installed and brake fluid
replaced at
aqualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the
functionality of your brakes at regular
intervals.
You can find adescription of Brake Assist
(BAS) on (Y page 64).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your
vehicle which have been approved for
Mercedes-Benz vehicles or which correspond
to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality could affect your
vehicle's operating safety.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
Checking brake liningt hickness You can measure the break pad/lining
thickness using
atest gauge.C olor-coding
(green or red) on the test gauge allows you to
determin ewhether the brake pad/lining
thickness is still sufficient .The test gauge is
in the vehicle document wallet in the glove
box. 158
