Intermittent wiping interval is dependent
on wetness of windshield.
Turn the combination switch to

After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
!Do not operate the windshield wipers
when the windshield is dry. Dust that
accumulates on a windshield might
scratch the glass and/or damage the
wiper blades when wiping occurs on a
dry windshield. If it is necessary to op-
erate the windshield wipers in dry
weather conditions, always operate the
windshield wipers with windshield
washer fluid (
page 57).
!Do not leave windshield wipers in
intermittent setting when the vehicle is
taken to an automatic car wash or
during windshield cleaning. Windshield
wipers will operate in the presence of
water sprayed on the windshield, and
windshield wipers may be damaged as
a result.
58 Getting startedDriving
Problems while driving
The engine runs erratically and misfires
An ignition cable may be damaged.
The engine electronics may not be op-
erating properly.
Unburned gasoline may have entered
the catalytic converter and damaged it
(Gasoline engine only).
Give very little gas.
Have the problem repaired by an au-
thorized Mercedes-Benz Center as
soon as possible.
!If anything blocks the windshield wip-
ers (leaves, snow, etc.), switch them off
immediately.
For safety reasons, stop the vehicle
in a safe location and
remove SmartKey from starter
switch
or
turn off the engine by pressing
the KEYLESS-GO* start/stop
button and open the driver’s
door (with the driver’s door
open, starter switch is in posi-
tion 0, same as with SmartKey
removed from starter switch)
before attempting to remove any
blockage.
Remove blockage.
Turn the windshield wipers on
again.
If windshield wipers fail to function at
all in combination switch positionI,
set the combination switch to the
next highest wiper speed
have the windshield wipers
checked at the nearest authorized
Mercedes-Benz Center.

As independent systems, their protective
functions work in conjunction with each
other. The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The
1
indicator lamp in the instrument
cluster lights up when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the
1
indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1
indicator lamp:
fails to go out after approximately
4 seconds after the engine was started
does not come on at all

the following driving safety systems:

BAS (B

ESP
® (E
lectronic S
tability P
rogram)
Electrohydraulic brake system
4MATIC (Four Wheel Electronic
Traction System)
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.
The - indicator lamp in the instrument
cluster comes on when you switch on the
ignition. It goes out when the engine is run-
ning.
iIn winter operation, the maximum ef-
fectiveness of the ABS, the BAS, the
ESP
®, electrohydraulic brake system
and 4MATIC is only achieved with win-
ter tires (
page 358), 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
®, electrohydraulic brake
system 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. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
94 Safety and SecurityDriving safety systemsBAS
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.
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 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 espe-
cially useful while driving off and on wet or
slippery road surfaces. The ESP® also sta-
bilizes the vehicle during braking maneu-
vers.
The ABS/ESP
® warning lamp v in the
instrument cluster flashes when the ESP
®
is engaged.
The ABS/ESP
® warning lamp v in the
instrument cluster comes on when you
switch on the ignition. It goes out when the
engine is running.
Warning!
G
If the BAS is malfunctioning, the brake sys-
tem is still functioning normally, but without
the additional brake boost available that
BAS would normally provide in an emergen-
cy braking maneuver. Therefore, the braking
distance may increase.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The BAS cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of a BAS 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.

Warning!
G
Never switch off the ESP
® when you see the
ABS/ESP
® warning lamp v flashing in
the instrument cluster. In this case proceed
as follows:
While driving off, apply as little throttle
as possible.
While driving, ease up on the accelera-
tor.
Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.

you use wheels of the recommended
tire size (page 473).
!Vehicles without 4MATIC:
Because of the ESP’s
® automatic oper-
ation, the engine and the ignition must
be shut off (SmartKey in starter switch
position0 or1 or KEYLESS-GO
start/stop button* in position0 or1)
when:
the parking brake is being tested on
a brake test dynamometer
the vehicle is being towed with the
front axle raised
Active braking action through the ESP
®
may otherwise seriously damage the
brake system.

4MATIC, see “Four wheel electronic
traction system (4MATIC) with the
ESP
®” (page 100).
100 Safety and SecurityDriving safety systems
After hard braking, it is advisable to
drive on for some time so that the air
stream will cool down the brakes fast-
er.
Only Mercedes-Benz approved compo-
nents (e.g. brake pads) should be in-
stalled on your vehicle. Brake pads not
approved by Mercedes-Benz may im-
pair the safety of your vehicle.
Four wheel electronic traction system
(4MATIC) with the ESP
®
Models with all-wheel-drive only.
The 4MATIC improves vehicle’s ability to
use available traction, e.g. during winter
operation in mountains under snowy
conditions, by applying power to all four
wheels.
