G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Warning!
G
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
front passenger airbag will not deploy only if
the
7
indicator lamp remains illuminat-
ed.
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmartTM restraint to transport children
on the front passenger seat until the system
has been repaired.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
front passenger seat. Signals from such de-
vices may interfere with the BabySmart
TM
system. Such signal interference may cause
the
7
indicator lamp not to come on
during self-test or be continuously lit, indi-
cating that the system is not functioning.

70 Safety and SecurityOccupant safetyChild seat anchors – “LATCH” type
This vehicle is equipped with two “LATCH”
(Lower A
nchors and T
ethers for CH
ildren)
type anchors (at each of the outer rear
seats) for the installation of a “LATCH”
child seat with the matching mounting fit-
tings.
The anchors are located between the seat
cushion and the backrest.

Grip inner side of anchors1 and fold
forward until they lock in place.

Install child seat according to the
manufacturer’s instructions.With a child seat installed in the left rear
seat, the seat belt for the center seat occu-
pied by a passenger must operate freely.
Guide seat belt between its seat cushion
anchor and backrest anchor along outside
of right side child seat anchor.
To fold anchors back

Press down button2 on each anchor
and return anchor to its catch.iThe child seat must be firmly attached
in the right and left side anchors1.iNon-“LATCH” type child seats may also
be used and can be installed using the
vehicle’s seat belt system. Install child
seat according to the manufacturer’s
instructions.
Warning!
G
Children too big for child restraint systems
must ride in back seats using regular seat
belts. Position shoulder belt across chest
and shoulder, not face or neck. A booster
seat may be necessary to achieve proper
belt positioning for children from 41 lbs. un-
til they reach a height where a lap/shoulder
belt fits properly without a booster.
Before installing the child seat, make sure
anchors1 are folded out and locked in
place.

Driving safety systems
In this section you will find information on
the following driving safety systems:

ABS (A
ntilock B
rake S
ystem)


BAS (B
rake A
ssist S
ystem)


ESP (E
lectronic S
tability P
rogram)


4MATIC* (Four Wheel Electronic Trac-
tion System)
ABS
The ABS regulates the brake pressure so
that the wheels do not lock during braking.
This allows you to maintain the ability to
steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode. Keep firm and steady
pressure on the brake pedal while experi-
encing the pulsation.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP and
4MATIC* is only achieved with winter
tires (M + S tires), or snow chains as re-
quired.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
ABS, BAS, ESP and 4MATIC* cannot reduce
this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal, rather use
firm, steady brake pedal pressure. Pumping
the brake pedal defeats the purpose for ABS
and significantly reduces braking effective-
ness.
S203 MY03_A.book Page 73 Tuesday, January 28, 2003 2:22 PM

74 Safety and SecurityDriving safety systemsContinuous steady brake pedal pressure
yields the advantages provided by 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
speedometer lights up when you turn the
key in the starter switch to position2. It
goes out when the engine is running.
More information can be found in the
“Practical hints” section (
page 255).
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
Warning!
G
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 af-
forded. The ABS cannot prevent accidents,
including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ABS equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of
others.

75 Safety and Security
Driving safety systems
BAS
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 the braking distance. Apply
continuous 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.
More information can be found in the
“Practical hints” section (
page 262).
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 starter switch to position2. It goes out
when the engine is running.
Warning!
G
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 afforded. The BAS
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties 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.

Warning!
G
Never switch off the ESP when you see the
ESP warning lamp
v
flashing in the
speedometer dial. In this case proceed as
follows:


While driving off, apply as little throttle
as possible


While driving ease up on the accelerator


Adapt your speed and driving style to
the prevailing road conditions
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.
Warning!
G
ESP cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it in-
crease the traction afforded. The ESP
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP 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.
