51 Getting started
Driving
Driving
Depress the brake pedal.
The gear selector lever lock is released.
Move gear selector lever in positionD
orR.
Release the brake pedal.
Carefully depress the accelerator
pedal.Once the vehicle is in motion, the
automatic central locking system engages
and the locking knobs drop down.
After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature faster.
Warning!
G
It is dangerous to shift the gear selector le-
ver out ofPorN if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.!In order to avoid damaging the trans-
mission,
wait for the gear selection process
to complete before setting the vehi-
cle in motion.
place the gear selector lever in
positionP orR only when the vehi-
cle is stopped.
!If you hear a warning signal and the
message: RELEASE
PARKING BRAKEappears in the multifunction display
when driving off, you have forgotten to
release the parking brake.
Release the parking brake.!Do not run cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.
80 Safety and SecurityDriving safety systemsIn this section you will find information on
the following driving safety systems:

BAS (B

ESP

tability P
rogram)
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, BAS, and the
ESP
® is only achieved with winter tires
(
page 313), 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
The ABS, BAS and ESP
® 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
The - indicator lamp in the instrument
cluster (
page 24) comes on when you
switch on the ignition (
page 34). It goes
out when the engine is running.
Braking
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 experiencing the pul-
sation.
Continuous steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and
functions as a reminder to take extra care
while driving.Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.
For more information, see “Practical hints”
(
page 328).
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.
Warning!
G
The 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 hydroplaning. 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.
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.
90 Controls in detailIn the “Controls in detail” section you will
find detailed information on how to oper-
ate the equipment installed in your vehicle.
If you are already familiar with the basic
functions of your vehicle, this section will
be of particular interest to you.
To quickly familiarize yourself with the ba-
sic functions of the vehicle, refer to the
“Getting started” section of this manual.
The corresponding page numbers are giv-
en at the beginning of each segment.Locking and unlocking

172 Controls in detailAutomatic transmissionGear selector lever one-touch gearshifting
Even with an automatic transmission, you
can change the gears manually and limit or
extend the gear range for automatic shift-
ing with the gear selector lever in
positionD and driving in the automatic
program modeC orS.Downshifting
Briefly press the gear selector lever to
the left in theD-direction.
The transmission will shift from the current
gear to the next lower gear as permitted by
the shift program. This action simulta-
neously limits the gear range of the
transmission (
page 170).Upshifting
Briefly press the gear selector lever to
the right in theD+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simul-
taneously extends the gear range of the
transmission.
Canceling gear range limit
Press and hold the gear selector lever
in theD+direction until
D reappears in
the tachometer display.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range
Press and hold the gear selector lever
in theD-direction.
The transmission will automatically select
the gear range suited for optimal
acceleration and deceleration. This may
involve shifting down one or more gears.
!Allow engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature
has been reached.
Shift into reverse gearR or parking
positionP only when the vehicle is
stopped.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause
serious damage to the drivetrain which
is not covered by the Mercedes-Benz
Limited Warranty.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.iTo avoid overrevving the engine when
the gear selector lever is moved to
theD-direction, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.
