68 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 braking distance. Apply con-
tinuous 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.
The malfunction indicator lamp for the ESP
is combined with that of the BAS.
The
¿
malfunction indicator lamp in
the instrument cluster lights up when you
turn the key in the steering lock to
position2. It goes out when the engine is
running.
More information can be found in the
“Practical hints” section.
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.

ometer dial flashes when the ESP is en-
gaged.
The warning lamp

Warning!
G
The 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.

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.

Active braking action through the ESP
may otherwise seriously damage the
rear axle brake system.
The ESP will only function properly if
you use wheels of the recommended
tire size.
70 Safety and SecurityDriving safety systemsSwitching off the ESP
To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have drive wheels spin
and thus cut into surfaces for better grip
such as:
starting out on slippery surfaces and in
deep snow in conjunction with snow
chains
sand or gravelThe switch is located on the center con-
sole.

Press upper half1 of the ESP switch
until the ESP warning lamp
v
in the
speedometer lights up.
The ESP is deactivated.
If one or more drive wheels are spinning,
the ESP warning lamp

in the speed-
ometer flashes, regardless of the speed.
Traction control brakes a spinning wheel
even when ESP is deactivated.ESP always operates when you are brak-
ing, even when it has been deactivated.
Switching on the ESP
Press lower half2 of the ESP switch.
The ESP warning lamp
v
in the
speedometer goes out. You are now
again in normal driving mode.
Warning!
G
The ESP should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
!Avoid spinning of a drive wheel for an
extended period with the ESP switched
off. This may cause serious damage to
the drivetrain which is not covered by
the Mercedes-Benz Limited Warranty.Warning!
G
When the ESP warning lamp
v
is
illuminated continuously, the ESP is
switched off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP.

transmission is found in the “Getting start-
ed” section (
page 40).
Gearshift leverDo not exceed the maximum speed in the
individual gears. Refer to tachometer
(page 89) for engine speeds.
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or re-
verse gear and parking brake engaged is
dangerous. Also, when parked on an incline,
an engaged first or reverse gear alone may
not prevent your vehicle from moving, possi-
bly hitting people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 47).
When parked on an incline, turn front wheels
towards the road curb.
Warning!
G
When leaving the vehicle, always remove the
key from the steering lock, and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Children could move the gearshift
lever, which could result in an accident
and/or serious injury.iNever hold the vehicle stopped on a hill
by using the clutch pedal. The clutch
may be damaged which is not covered
by the Mercedes-Benz Limited
Warranty.

Automatic transmission*
Automatic transmission*
Information for driving with an automatic
transmission is found in the “Getting start-
ed” section (
page 41).
Your transmission adapts its gear shifting
process to your individual driving style by
continually adjusting the shift points up or
down. These shift point adjustments are
performed based on current operating and
driving conditions.
If the operating conditions change, the au-
tomatic transmission reacts by adjusting
its gear shift program.
The automatic transmission selects indi-
vidual gears automatically, dependent
upon
the selector lever positionD with gear
ranges4, 3, 2, 1 (
page 95)
the selected shift program (W/S)
(page 97)
the position of the accelerator pedal
(page 98)
the vehicle speed
1Gear range indicator display
The current selector lever position appears
in gear range indicator display1.When the selector lever is in positionD,
you can influence transmission shifting by
limiting the gear range
changing gears yourself
iDuring the brief warm-up, the transmis-
sion upshifting is delayed. This allows
the catalytic converter to heat up more
quickly to operating temperatures.
Warning!
G
It is dangerous to shift the selector lever out
ofP orN if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the en-
gine is idling normally and when your right
foot is firmly on the brake pedal.

Effect
P
Park position
Selector position when the vehicle
is parked. Only place selector lever
in positionP when vehicle is
stopped. The park position is not in-
tended to serve as a brake when
the vehicle is parked. Rather, the
driver should always set the park-
ing brake in addition to placing the
selector lever in positionP to se-
cure the vehicle.
The key can only be removed from
the steering lock with the selector
lever in positionP. With the key re-
moved the selector lever is locked
in positionP.
Effect
R
Reverse gear
Place selector lever in positionR only
when vehicle is stopped.
N
Neutral
No power is transmitted from the en-
gine to the drive axle. When the
brakes are released, the vehicle can
be moved freely (pushed or towed).
To avoid damage to the transmission,
never engageN while driving.
If the ESP is deactivated or malfunc-
tioning:
Only move selector lever toN if the
vehicle is in danger of skidding (e.g.
on icy roads).
D
Drive
The transmission shifts automatical-
ly. All five forward gears are avail-
able.
!Coasting the vehicle, or driving for any
other reason with selector lever inN
can result in transmission damage that
is not covered by the Mercedes-Benz
Limited Warranty.Warning!
G
Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. Also, positionP alone is not intend-
ed to or capable of preventing your vehicle
from moving, possibly hitting people or ob-
jects.
Always set the parking brake in addition to
shifting to positionP (
page 47).
When parked on an incline, turn front wheels
towards the road curb.
