infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer’s instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:
R USA only: Your vehicle is equipped with air
bag technology designed to deactivate the
front passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front passenger seat.
R USA only: For children larger than the
typical 12-month-old child, the front
passenger front air bag may or may not be
activated. Always make sure the
42 indicator lamp is
illuminated, indicating that the front
passenger front air bag is deactivated.
R Canada only: Children 12 years old and
under must never ride in the front seat,
except in a Mercedes-Benz authorized
BabySmart™ compatible child seat, which
operates with the BabySmart™ system
installed in the vehicle to deactivate the
front passenger front air bag when it is
installed properly. Otherwise they will be
struck by the air bag when it inflates in a
crash. If this happens, serious or fatal injury
will result.R A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
place a child in a rear-facing child restraint
in the front seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint in a backseat.
R If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 42
indicator lamp is illuminated, indicating
that the front passenger front air bag is
deactivated. Should the 42
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
42 indicator lamp while
driving to make sure the 42
indicator lamp is illuminated. If the
42 indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.
A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
R If you have to place a child in a forward-
facing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle’s seat belt according to the child
seat manufacturer’s instructions.GWarning!
Infants and small children should never share
a seat belt with another occupant. During an

accident, they could be crushed between the
occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Position
shoulder belt across chest and shoulder, not
face or neck. A booster seat may be
necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap/shoulder belt
fits properly without a booster.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat
belt to prevent the child restraint from
becoming a projectile in the event of an
accident.

systems
GObserve Safety notes, see page 55.GWarning!
Always lock the seat backrests in their upright
position when the rear seats are occupied by
passengers. Lock the seat backrests in their
upright position after installing top tether
straps or when the extended cargo
compartment is not in use. Make sure that
seat backrests are secured properly by
pushing and pulling on the seat backrests. If
a seat backrest is not locked properly, the
seat backrest could fold. The child seat would
no longer be supported properly or positioned
to provide its intended benefit. That could
cause serious or even fatal injuries.
This vehicle is equipped with tether
anchorages for a top tether strap at the
second-row seat backrest. For installing an
infant and child restraint system at the
third-row seats, use the cargo tie-down rings
in the cargo compartment (Y page 200).
Top tether straps enable an additional
connection to be made between child
restraint systems secured with LATCH-type
anchors and rear seats. This can further
reduce the risk of injury.

achieved with winter tires, or snow chains
as required.
Safety notesGWarning!
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.
ABS
GObserve Safety notes, see page 62.GWarning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
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
approximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! indicator lamp
in the instrument cluster comes on when you
switch on the ignition. 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. The pulsation indicates that the
ABS is in the regulating mode.
XKeep firm and steady pressure on the brake
pedal while you feel the pulsation.
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
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver
XKeep continuous full pressure on the brake
pedal.GWarning!
If the ABS malfunctions, other driving safety
systems such as the BAS or the ESP ®
are also
switched off. Observe indicator and warning
lamps that may come on as well as messages
in the multifunction display that may appear.
62Driving safety systemsSafety and security
X164_AKB; 5; 31, en-USd2ureepe,Version: 2.11.8.12009-09-11T12:30:16+02:00 - Seite 62

If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability and extending the braking distance.
Off-road ABS
With the off-road driving program switched
on, or with the transmission in LOW RANGE
mode, the ABS designed for off-road driving
is activated automatically.
When applying the brakes at speeds below
18 mph (30 km/h), the front wheels are
locked cyclically to shorten the braking
distance (dig-in effect). This will restrict
steering the vehicle.
BAS
GObserve Safety notes, see page 62.
The Brake Assist System (BAS) operates in
emergency situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
XApply 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.
GWarning!
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.
EBP
GObserve Safety notes, see page 62.
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
the rear brakes to supply a greater proportion
of the braking effort in straight-line braking
without a loss of vehicle stability.GWarning!
If the EBP malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.
ESP ®
GObserve Safety notes, see page 62.
The Electronic Stability Program (ESP
®
) is
operational as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP ®
recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels 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 and
steering maneuvers.
The ESP ®
warning lamp d in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
The ESP ®
warning lamp d in the
instrument cluster flashes when the ESP ®
is
engaged.
Driving safety systems63Safety and securityX164_AKB; 5; 31, en-USd2ureepe,Version: 2.11.8.12009-09-11T12:30:16+02:00 - Seite 63Z

GWarning!
Never switch off the ESP®
when you see the
ESP ®
warning lamp d flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R 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.
! Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system or the transfer case which is not
covered by the Mercedes-Benz Limited
Warranty.
! Because the ESP ®
operates
automatically, the engine and ignition must
be shut off (SmartKey in starter switch
position 0 or 1 or KEYLESS-GO start/stop
button in position 0 or 1) when the parking
brake is being tested on a brake test
dynamometer. Such testing should be no
longer than 10 seconds.
Active braking action through the ESP ®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! The ESP ®
will only function properly if you
use wheels of the recommended tire size
as specified in the “Technical data” section
of this Operator’s Manual.
i The Distronic system and cruise control
switch off automatically when the ESP ®
engages.
Electronic Traction System (4-ETS) GObserve Safety notes, see page 62.
The 4-ETS (four-wheel Electronic Traction
System) is a component of the ESP ®
. The
4-ETS improves the vehicle’s ability to utilize
available traction, especially under slippery
road conditions by applying the brakes to a
spinning wheel. In addition, more power is
transferred to the wheel(s) with traction.
When you switch off the ESP ®
, the 4-ETS is
still enabled.
XIf conditions require, switch on the off-road
driving program ( Y page 158) or the LOW
RANGE mode ( Y page 119).
Off-road 4-ETS
With the off-road driving program switched on
( Y page 158), or the transmission in LOW
RANGE mode ( Y page 120), the 4-ETS
designed for off-road use is activated
automatically.
Switching off the ESP ®
GWarning!
The ESP
®
should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP ®
when a spare
wheel is mounted.
To improve the vehicle’s traction, switch off
the ESP ®
. This allows the drive wheels to spin
and thus cut into surfaces for better grip, for
example
R when driving with snow chains
R in deep snow
R in sand or gravel

GWarning!
Switch on the ESP® immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the ESP® will not
stabilize the vehicle when it is starting to skid
or a wheel is spinning.

iWhen the ESP® is switched off and one or
more drive wheels are spinning, the ESP®
warning lamp d in the instrument
cluster flashes. However, the ESP® will
then not stabilize the vehicle.
XWith the engine running, press ESP®
switch : until the ESP® warning lamp
d in the instrument cluster comes on.
The ESP® is switched off.
GWarning!
When the ESP® warning lamp d is
illuminated continuously, the ESP® is
switched off or is not operational due to a
malfunction. Vehicle stability in standard
driving maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESP®.
! 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.
Switching on the ESP®
XPress ESP® switch : until the ESP®
warning lamp d in the instrument
cluster goes out.
You are now again in normal driving mode
with the ESP® switched on.
Off-road ESP®
With the off-road driving program switched on
(Y page 158), or with the transmission in
LOW RANGE mode (Y page 120), the ESP®
designed for off-road use is activated
automatically. At speeds below 27 mph
(45 km/h), the ESP® assists in over–
understeering, thus improving vehicle
traction.
ESP® trailer stabilization
If the trailer you are towing should begin to
sway, the rig can only be stabilized by
immediately applying the brakes hard.
Steering during this maneuver will not help to
stabilize the rig.
The ESP® will assist you in such situations.
The ESP® recognizes when the trailer starts
swaying and will apply the brakes to reduce
the vehicle speed to a non-critical speed that
