Have the problem repaired by an au-
thorized Mercedes-Benz Center as
soon as possible.
!If anything blocks the windshield
wipers (leaves, snow, etc.), switch
them off immediately.
For safety reasons, withdraw
SmartKey from starter switch
before attempting to remove any
blockage.
The hood must be opened
(page 243) before folding the
wiper arms away from the wind-
screen. You could otherwise dam-
age the hood and/or the wiper arm.
Remove blockage.
Turn the windshield wipers on
again.
If windshield wipers fail to function at
all in switch positionI,
set the combination switch to the
next highest wiper speed

You have properly stopped and parked
your vehicle. End your drive as follows.
Parking brake
1Parking brake lever
Pull parking brake lever1 up as many
notches as possible.
When the engine is running, the
warning lamp; (USA only)
or3(Canada only) in the
instrument cluster will be illuminated.
Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
system. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Pull the parking brake lever up as many
notches as possible.
Move the gear selector lever to
positionP.
Slowly release brake pedal.
When parked on an incline, turn front
wheels towards the road curb.

Occupant safety
Infant and child restraint systems
Only use a BabySmart
TM1
compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
The passenger lap-shoulder belt has a spe-
cial seat belt retractor for the secure fas-
tening of child restraints.
To fasten a child restraint follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During the seat belt retraction a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual
manner.

Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.
!The use of infant or child restraints is
required by law in all 50 states, the Dis-
trict of Columbia, the U.S. territories,
and all Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system which is properly
secured by a lap-shoulder belt and top
tether strap that complies with U.S.
Federal Motor Vehicle Safety
Standard 213 and Canadian Motor
Vehicle Safety Standard 213.
A statement by the child restraint man-
ufacturer of compliance with this stan-
dard can be found on the instruction
label on the restraint and in the instruc-
tion manual provided with the restraint.

In this section you will find information on
the following driving safety systems:
ABS (A

ESP (E
lectronic S
tability P
rogram)
SBC (S

ontrol)
ABS
The Antilock Brake System (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.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP, and the SBC is only achieved with
winter tires (M + S tires) or snow chains
as required.
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
The ABS, BAS, ESP, and SBC 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. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
81 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 potential-
ly 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.
ESP
The Electronic Stability Program (ESP) is
operational as soon as the engine is run-
ning and 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
spinning or if the vehicle starts to skid. By
applying brakes to the appropriate wheel
and by limiting the engine output, the ESP
works to stabilize the vehicle. The ESP is
especially useful while driving off and on
wet or slippery road surfaces. The ESP also
stabilizes the vehicle during braking ma-
neuvers.
The ABS/ESP warning lamp v in the in-
strument cluster (
page 29) flashes when
the ESP is engaged.
The ABS/ESP warning lamp v in the
instrument (
page 28) cluster comes on
when you switch on the ignition. 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. The BAS cannot
prevent accidents, including those resulting
from excessive speed in turns, following an-
other vehicle too closely, or hydroplaning.
Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities 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.
85 Safety and Security
Driving safety systems
The SBC brake system is automatically ac-
tivated when you
unlock the vehicle with the SmartKey
open the driver’s or passenger door
turn the SmartKey in the starter switch
to position1
depress the brake pedal
release the parking brake
If there is a malfunction in the SBC brake
system, we recommend that the vehicle be
transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment.
A tow bar must be used if circumstances do
not permit the use of the recommended
towing methods and the vehicle requires
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on
the ground is only permissible for distances
u p t o 3 0 m i l e s ( 5 0 k m ) a n d a t a s p e e d n o t t o
exceed 30 mph (50 km/h). For more infor-
mation, see “Towing the vehicle”
(page 357).
iIf the SBC brake system is activated as
the brake pedal is first depressed, you
may feel a reduced pedal resistance
and longer pedal travel than normal.
When releasing the pedal, you may also
feel the brake pedal pulsate and you
may hear a sound which is caused by
the activation of the SBC pump. This is
normal and not an indication of a mal-
function. Pedal travel returns to normal
when you release the brake pedal and
the sound soon ceases.
If you experience the above while driv-
ing and the red brake warning lamp
(page 298) illuminates and/or warn-
ing messages appear in the multifunc-
tion display (
page 312), the brake
system is malfunctioning. Follow the in-
structions of the warning message(s)
and have the brake system checked
immediately.
Warning!
G
Have brake pad replacement and other work
on the SBC brake system carried out by
qualified technicians only. Contact your
Mercedes-Benz Center for further informa-
tion. The SBC brake system must be deacti-
vated prior to working on the system. High
pressure is intermittently built up in the sys-
tem as part of its automatic self-test. In ad-
dition, the system is automatically activated
when the vehicle is unlocked by remote con-
trol, when the driver or passenger door is
opened, when the SmartKey in the starter
switch is turned to position1, when the
brake pedal is depressed or when the park-
ing brake is released. Failure to deactivate
the system prior to maintenance will cause
brake pistons to extend and brake fluid to
leak, which may result in injuries (contu-
sions and acid burns). Extended brake
pistons may also cause injury.
