72 Safety and SecurityDriving safety systemsContinuous steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the 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
-
indicator lamp in the instrument
cluster lights up when you turn the key in
the starter switch to position2 or press
the KEYLESS-GO* start/stop button twice.
It goes out when the engine is running.
More information can be found in the
“Practical hints” section (
page 265).
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
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. The
ABS cannot prevent accidents, including
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 an ABS 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.

Lumbar support
You can adjust the contour of the seat’s
lumbar support to best support your back.
The thumbwheels for the driver’s and front
passenger’s seat are on the inner side of
the seat.
1Thumbwheel
Make sure the ignition is switched on.
All the lamps in the instrument cluster
should light up.
Set the lumbar support between 0
and 5.
Easy-entry / exit feature
With the easy-entry / exit feature activat-
ed, the steering wheel tilts upwards and
the driver’s seat moves to the rear.
This allows easier entry into and exit from
the vehicle when the driver’s door is
opened. However, the engine must be
turned off.
When the SmartKey is inserted in the start-
er switch or you have pressed the
KEYLESS-GO* start / stop button once and
the driver’s door is closed, the steering
wheel and the driver’s seat return to their
last set positions.You can activate the following functions:
Steering column:
Only the steering column is adjusted.
Steering column and seat:
Both the steering column and the seat
are adjusted.
The easy-entry / exit feature can be
switched on or off in the in the settings
menu of the control system (
page 140).
Warning!
G
You must make sure that no one can be-
come trapped or injured by the moving
steering wheel and driver’s seat when the
easy-entry / exit feature is activated, the
driver’s door is being opened, and the en-
gine is turned off or the SmartKey removed
from the starter switch. Do not leave chil-
dren unattended in the vehicle, or with ac-
cess to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause an ac-
cident and/or serious personal injury.

Warning!
G
The seat belts provide protection only with
the backrest locked in place and, therefore,
must be locked in place with the vehicle in
motion. Do not drive the vehicle when the
backrest is not locked in place. If the warn-
ing message
SEAT BACKREST, RIGHT -
LOCK
or
SEAT BACKREST, LEFT - LOCK
is
displayed in the multifunction display, then
the respective backrest is not engaged in its
lock. Carefully slow down, and drive with
caution to an area which is in a safe distance
from the roadway. Always provide sufficient
room behind the backrest and fold the back-
rest all the way back until it locks in place.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
The warning message is no longer displayed
as soon as the backrest is locked in place. If
both backrests are locked in place and the
warning message is still displayed, have the
system checked at your authorized Mer-
cedes-Benz Center immediately.
When leaving the vehicle, always remove the
electronic key from the starter switch, take
the KEYLESS-GO* card with you, and lock
your vehicle.
The power seats can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
Never place hands under seat or near any
moving parts during a seat adjustment pro-
cedure.
!The automatic seat slide is provided
with a safety feature.
The automatic process is interrupted, if
the backrest of the sliding seat is
pushed against an occupant or object.
The seat will slide forward and stop.
Investigate and correct the cause of in-
terruption.
Now use memory button (
page 105)
or seat adjustment switch (page 35)
to bring seat into desired position.
When folding the backrest forward
from a reclined position, and then fold-
ing it back, the backrest stops in a
more upright position for the safety of
any rear-seat passenger. Adjust the
backrest until your arms are slightly an-
gled when holding the steering
wheel (
page 35).

!Prior to operating the vehicle, the driv-
er should check and adjust the seat
height, seat position fore and aft, and
seat backrest angle if necessary, to en-
sure adequate control, reach and com-
fort. The head restraint should also be
adjusted for proper height. Also see
“Airbag” section (
page 55) for proper
seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the inside and
outside rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in a properly
secured restraint system that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213
and 210.2.

Coolant temperature gauge
During severe operating conditions and
stop-and-go city traffic, the coolant tem-
perature may rise close to 248° F (120°C),
i.e. close to the red zone of the coolant
temperature gauge.The engine should not be operated with
the coolant temperature above 248° F
(120°C), i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not cov-
ered by the Mercedes-Benz Limited War-
ranty.

Driving when your engine is badly over-
heated can cause some fluids which
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.
Steam from an overheated engine can
cause serious burns and can occur just
by opening the engine hood. Stay away
f r o m t h e e n g i n e i f y o u s e e o r h e a r s t e a m
coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down.
iExcessive coolant temperatures trigger
a warning in the multifunction display
(page 278).
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
