Important safety notes
G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly 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. Never drive with the tailgate open. G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
! The tailgate swings upwards and out when
opening. Therefore, make sure that there is
sufficient space above the tailgate.
The opening dimensions of the tailgate can be
found in the "Vehicle data" section
(Y page 281).
If the rear spoiler has been extended manually,
the height when opened is higher by this
amount. If in doubt, retract the rear spoiler again manually before opening the tailgate
(Y page 224).
You can switch the luggage compartment light-
ing on and off manually on the overhead control
panel (Y page 91).
Do not leave the key in the luggage compart-
ment. You could otherwise lock yourself out.

Important safety notes G
WARNING
The vehicle exhaust system can become very
hot. If you unlock the luggage compartment
with KEYLESS-GO, you could burn yourself by touching the exhaust system. There is a risk of
injury. Always ensure that you only make the required kicking movement within the detec-
tion range of the sensors.
! If the key is within the rear detection range
of KEYLESS-GO, the following situations, for
example, could lead to the unintentional
opening of the tailgate:
R using a car wash
R using a high-pressure cleaner
Make sure that the key is at least 3 m away
from the vehicle.
General notes Vehicles with KEYLESS-GO without carbon
package:
you can unlock the tailgate without
using your hands. This is useful if you have your hands full. To do this, make a kicking movement
under the rear bumper with your foot.
Observe the following points:
R Carry your KEYLESS-GO key about your per-
son. The KEYLESS-GO key must be in the rear
detection range of the vehicle.
R When making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clearance
to the rear of the vehicle. You could otherwise
lose your balance, e.g. on ice. R
Always ensure that you only make a kicking
movement within the detection range of sen- sors :.
R Stand at least 30 cm away from the rear area
while doing so.
R Do not come into contact with the bumper
while making the kicking movement. Other-
wise, the sensors may not function correctly.
R Unlocking with KEYLESS-GO does not func-
tion when the engine is started. 72

Dirt caused by road salt around sensors :
may restrict functionality.
Using HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
R If a KEYLESS-GO key is within the rear detec-
tion range of KEYLESS-GO, the sensors could be triggered. Therefore, the tailgate cannot beunlocked unintentionally if, for example, you:
- sit on the edge of the luggage compartment
- set down or lift up an object behind the
vehicle
- polish the rear of the vehicle
Do not carry the KEYLESS-GO key about your
person in such situations. This prevents the
tailgate from being unlocked unintentionally.

children unattended in the vehicle. Side window reversing feature
The side windows are equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts a side window from travelling
upwards during the automatic closing process,
the side window opens again automatically. Dur- ing the manual closing process, the side window only opens again automatically after the corre-
sponding switch is released. The automatic
reversing feature is only an aid and is no substi-
tute for your attention when closing a side win-
dow. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. small fin-
gers

handle :is depressed, the greater the brak-
ing force. During braking:
R a warning tone sounds
R the Release parking brake
Release parking brake display mes-
sage appears
R the red !indicator lamp on the instrument
cluster flashes
When the vehicle has been braked to a stand-
still, the electric parking brake is applied. Parking up the vehicle
General notes If you leave the vehicle parked up for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
If you leave the vehicle parked up for longer than
six weeks, it may suffer from lack of use.
X Contact a qualified specialist workshop and
seek advice.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop.
Charge retention of the on-board elec-
trical system battery The battery may drain if the vehicle is left sta-
tionary for long periods. In this case, Mercedes- Benz recommends attaching the trickle charger
to the 12 V socket in the luggage compartment. A trickle charger can be obtained from a
Mercedes-Benz Service Centre, for example.
X Switch the ignition off.
X Open the tailgate. 122
ParkingDriving and parking

X
Connect the cable provided in the luggage
compartment to the trickle charger.
X Connect the trickle charger to 12 V socket :.
Consult the manufacturer's operating instruc- tions on how to do so.
The tailgate can be closed, even if a trickle
charger is connected. Make sure that the con-
nector for both the connector cables is outside
of the vehicle.
The connector can then separate if the vehicle is
moved, even if you forget to disconnect the con- nector cables. This prevents damaging the
cables and the trickle charger.
A trickle charger connected to 12 V socket :
only maintains the current charge level of the
vehicle's electrical system battery. If the vehi-
cle's electrical system battery is discharged, it
needs to be charged with a battery charger. Driving tips
General driving tips
Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving.
Drive sensibly – save fuel Observe the following tips to save fuel:
X The tyres should always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the Ser-
vice Booklet or by the service interval display.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. Brakes
Important safety notes G
WARNING
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.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Shift to a lower gear in good time on long and
steep downhill gradients. Take particular note of
this when driving a laden vehicle.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
This will use the braking effect of the engine, so less braking will be required to maintain the
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Heavy and light loads G
WARNING
The braking system can overheat if you leave your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There is
a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If heavy demands are made on the brakes, do
not park the vehicle immediately. Drive on for a
short while. This allows the airflow to cool the
brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effectiveness.
To do this, brake more firmly from a higher
speed while paying attention to the traffic con-
ditions. This improves the grip of the brakes. Driving tips
