Knee Bag; Side Impact Air Bag - Mercedes-Benz SLK350 Operator's Manual

They are deployed:
in the event of certain frontal impacts
R
if the system determines that air bag
R
deployment can offer additional protection
to that provided by the seat belt
if the seat belt is fastened
R
independently of other air bags in the
R
vehicle
If the vehicle overturns, the front air bags are
generally not deployed. If the system detects
high vehicle deceleration in a longitudinal
direction, the front air bags are deployed.
Your vehicle has adaptive, two-stage front air
bags. In the event of a collision, the air bag
control unit evaluates the vehicle
deceleration. In the first deployment stage,
the front air bag is filled with enough
propellant gas to reduce the risk of injuries.
The front air bag is fully deployed if a second
deployment threshold is exceeded within a
few milliseconds.
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) ( page 42).
Y
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 a low impact severity is
predicted. You will then be protected by the
fastened seat belt.
The front-passenger front air bag will only
deploy if:
the system, based on the OCS weight
R
sensor readings, detects that the front-
passenger seat is occupied.
the ^a indicator lamp in the center
R
console is not lit, ( page 42).
Y
the air bag control unit predicts a high
R
impact severity.
Knee bags
G WARNING
Observe "Important safety notes"
( page 38).
Y
Knee bags provide increased protection for
the driver and front passenger against the risk
of:
knee injuries
R
thigh injuries
R
lower leg injuries
R
Driver's knee bag ?( page 39) deploys

underneath the steering column and front-
passenger knee bag =(
Y
underneath the glove box. They deploy
together with the front air bags. They are
designed to operate together with the front
air bags in frontal impacts if certain
thresholds are exceeded. The knee bags
operate at best in conjunction with correctly
positioned and fastened seat belts.
Side impact air bags
G WARNING
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door
trim panels including, for example, the
addition of door speakers.
Improper repair work on the doors or the
modification or addition of components to the
doors create a risk of rendering the side
impact air bags inoperative or causing
unintended air bag deployment. Work on the
