You must reset the electric sliding door if there
has been a malfunction or an interruption in the
voltage supply (
Ypage 78).
iPlease note, if the child-proof locks have
been activated, you cannot open the sliding
door from the inside. You can only open a
sliding door from the inside if the child-proof
locks have not been activated. Further infor-
mation can be found under "Child-proof locks
for the sliding door" (
Ypage 63) and "Open-
ing/closing from the inside" (Ypage 77).
Obstacle detection with reversing
feature
The sliding door is equipped with automatic
obstacle detection with reversing feature. If a
solid object blocks or restricts the sliding door
during the automatic closing process, the slid-
ing door opens again automatically. If the sliding
door is obstructed during the opening proce-
dure, it moves back a few centimeters in the
opposite direction and stops.
Automatic obstacle detection with reversing
feature is only an aid. It is not a substitute for
your attentiveness when closing the electrical
sliding door.
If an obstacle is detected, the display shows the
Left-hand Electric Sliding Door
ObstructionDetectedmessage for example,
and five warning tones sound.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 8 mm of the closing movement

The air vents can only be adjusted on vehicles
with rear-compartment air conditioning.
Vehicles with rear-compartment air condition-
ing: in heating mode, the air in the rear com-
partment is automatically distributed in the foot-
wells and roof area after the coolant has
reached the required temperature. In cooling
mode, in the initial phase the air is distributed in
the footwells and roof area of the hot vehicle,
and subsequently only in the roof area.

Always use the hands-free system for telephon-
ing while driving. Only use the telephone if road
traffic conditions permit. If this is not the case,
pull over to a safe location before using the tele-
phone.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is cov-
ering a distance of 44 fee t(approximately 14 m)
every second.
Drive sensibly – save fuel
In order to save fuel, observe the following tips:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the Main-
tenance Booklet or by the service interval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in moun-
tainous terrain.
Overrun cutoff
If you are in overrun mode and take your foot off
the accelerator pedal, the fuel supply is cut off
when the engine speed is out of the idle speed
control range.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the man-
ufacturer's specifications. Any work on the
engine should therefore be carried out by quali-
fied and authorized Mercedes-Benz technicians.
The engine settings must not be changed under
any circumstances. In addition, all specific
maintenance work must be carried out at regu-
lar intervals and in accordance with the service
requirements of the dealer listed here on the
inside title page. Details can be found in the
Maintenance Booklet.
Speed limiter
GWARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed could
lead to tire damage or the tire bursting. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe the
tire load rating and speed rating required for
your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the maxi- mum permissible speed based on the tires (tire
and tire pressure). In particular, also observe the tire approval regulations for each country.
You must not exceed the speed limit for the tires
indicated by the speed rating. The speed rating
is stated in the tire tables (
Ypage 302).
You can permanently limit the permissible max-
imum speed of your vehicle, e.g. for driving on
winter tires.
138Driving tips
Driving and parking

110 yds (100 m) at a maximum speed of 12 mph(20 km/h).
The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
Driving in wet conditions
Hydroplaning
GWARNING
There is a danger of hydroplaning occurring,
even if you are driving slowly and your tires
have sufficient tread depth, depending on the
depth of water on the road. There is a risk of
an accident.
For this reason, avoid tire ruts and brake care-
fully.
Therefore, in heavy rain or other conditions in
which hydroplaning can occur, drive as follows:
Rreduce your speed
Ravoid tire ruts
Rapply the brakes with care
Driving on flooded roads
!Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
Rthe water level of standing water should not
be above the lower edge of the front bumper
Rdo not drive faster than walking speed
Driving in winter
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
!An accumulation of snow and ice, particu-
larly when frozen, caught in the area around
the air intake slots, moving parts, the axles
and the wheel arches may:
Rrestrict air intake
Rdamage vehicle parts
Rcause malfunctions by restricting the mobi-
lity intended by the design (e.g. reduced
possible steering input).
Regularly check the vehicle and remove snow
or ice when traveling in wintry conditions.
If there is any damage, inform a qualified spe-
cialist workshop.
!Vehicles with automatic transmission may
roll only briefly in the neutral position N. Pro-
longed rolling of the wheels, e.g. when being
towed, will result in transmission damage.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and braking
maneuvers. Do not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
XTry to maintain control of the vehicle using
corrective steering.
The outside temperature indicator is not
designed to serve as an ice-warning device and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. If you do not adjust
your driving style, the vehicle may start to skid.
Al

ways adapt your driving style and drive at a
speed to suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Loading guidelines
Important safety notes
GWARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be thrown
about, striking vehicle occupants. This also
applies to:
Rluggage or loads
Rseats which have been removed and are
being transported in the vehicle in an
exceptional case.
There is a risk of injury, particularly in the
event of a braking maneuver or abrupt change
in direction.
Always stow objects in such a way that they
cannot be tossed about. Before traveling,
secure objects, luggage or loads to prevent
them slipping or tipping over. If you remove a
seat, store it preferably outside the vehicle.
GWARNING
As a result of improperly placed or unevenly
distributed loads, the center of gravity of the
load being transported may be too high or too
far back. This can significantly impair handling
as well as steering and braking characteris-
tics. There is a risk of an accident.
Always make sure that the center of gravity of
the load is:
Rbetween the axles
and
Ras low as possible, near the rear axle.
GWARNING
When the permissible wheel loads, axle loads
and/or the maximum permissible gross vehi-
cle weight are exceeded, driving safety is
compromised. The handling as well as steer-
ing and braking characteristics may be signif-
icantly impaired. Overloaded tires may over-
heat, causing them to burst. There is a risk of
an accident.
When transporting a load, always observe the
permissible wheel loads, axle loads and the
maximum permissible gross vehicle weight
for the vehicle (including occupants).
!If you are using a roof carrier, observe the
maximum roof load and maximum roof carrier
load.
RDo not stack luggage or loads higher than the
backrests.
RObjects to be transported should preferably
be stowed in the cargo compartment.
RWhen transporting luggage, always use the
cargo tie-down rings for securing loads and a
cargo net, if installed.
RUse cargo tie-down rings and fasteners which
are suitable for the weight and size of the
load.
When using suitable load securing aids and tie
downs, always follow the manufacturer's oper-
ating instructions, in particular the notes on dis-
card criteria contained therein.
Load securing aids or tie downs must not be
used if:
Ridentification marks are missing or illegible
Rthere are yarn breakages, damage to bearing seams or other signs of tearing
Rthere are signs of shearing, deformation,
pinching or other damage
Rthere is damage to clamping or connecting
elements
Load securing aids and tie downs in this condi-
tion are ready for discard and must be replaced.
If you use load securing aids or tie downs which are worn out, the load may not be sufficiently
secured and could cause damage to property.
244Loading guidelines
Transporting loads

In the event of an accident, have a damaged
cargo compartment floor or loading area, the
cargo tie-down rings and the tie down checked
at a specialist workshop. Otherwise, the load
may not be correctly secured the next time any-
thing is stowed.
Even if you follow all loading guidelines, the load
increases the risk of injury in the event of an
accident. Observe the information in the "Secur-ing a load" (
Ypage 246) and "Load distribution"
(Ypage 245) sections.
You will find information about the maximum
roof load under "Cargo tie-down points and car-
rier systems" (
Ypage 314). You will find infor-
mation about roof carriers under "Carrier sys-
tems" (
Ypage 250).
Before loading
!
The anti-slip mats cannot be used for secur-
ing goods and must be replaced when they
show signs of:
RPermanent deformation and crushing
RCrack formation
RCuts
XTire pressure: check the tire pressure and
correct if necessary (Ypage 282).
XCargo compartment floor: clean the cargo
compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to pre-
vent the load from slipping.
XPlace non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary.
During loading
XObserve the gross axle weight rating and per-
missible gross vehicle weight for your vehicle.
Take into account that your vehicle's curb
weight is increased if accessories or optional equipment are installed. The maximum pay-
load is thus reduced.
XObserve the notes on load distribution
(Ypage 245).
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.
XSecure the load (Ypage 246).
Observe the legal requirements of the country
in which you are currently driving.
Checks after loading
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tail-
gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is a risk of poisoning.
Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open.
XSecuring luggage/loads: make sure that
the luggage and/or load is secure before
every journey and at regular intervals during a
long journey, and correct it if necessary.
XDoors/tailgate: close the sliding doors and
tailgate/door.
XTire pressure: adjust the tire pressure
according to the vehicle load (Ypage 282).
XDriving style: adapt your driving style
according to the vehicle load.
Load distribution
General notes
!
Excessive loads on individual points of the
cargo floor or on the load surface impair vehi-
cle handling characteristics and could cause
damage to the floor covering.
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.
Load distribution245

GWARNING
If vehicle occupants are seated behind a load
protection net, they may be squeezed up
against the load protection net. There is a risk
of injury, particularly in the event of braking
maneuvers or abrupt changes in direction.
Never allow vehicle occupants to sit behind
the load protection net.
The load protection net borders the cargo com- partment. It protects vehicle occupants from
light objects and/or luggage slipping or tipping
over. Always observe the notes on securing
loads (
Ypage 246).
You can install the load protection net at an
angle behind the front seats or behind the first
row of back seats.

Carrier systems
GWARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character-
istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.
There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
