Starting the engine
Important safety notes
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.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system orparts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
!Do not depress the accelerator when
starting the engine.
Starting procedure
X Shift the automatic transmission to posi-
tion P.
The transmission position display in the
multifunction display shows P.
iFor further information about the auto-
matic transmission, see ( Ypage 105).
iIf you depress the brake when starting the
engine, pedal travel is unusually long and
there is less pedal resistance.
X Make sure that the parking brake is
applied.
X Turn the SmartKey to position 3
( Y page 103) in the ignition lock and release
it as soon as the engine is running.
iYou can also use the touch-start function.
To do this, turn the SmartKey to position 3
( Y page 103) and release it immediately.
The engine then starts automatically.
Pulling away
Automatic transmission
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
!Only shift the automatic transmission to
reverse gear Ror park position Pwhen the
vehicle is stationary. Otherwise, the auto-
matic transmission could be damaged.

Cruise control
Important safety notes
GWARNING
The brake pedal moves when cruise control
brakes the vehicle. A foot in the area under
the brake pedal could become trapped. The
movement of the pedal, and therefore the
vehicle's ability to brake, may be restricted by objects in the area under the brake. There is a
risk of an accident and injury.
112Driving systems

stored. Otherwise, it sets the vehicle cruisespeed to the previously stored value.
Driving with DISTRONIC PLUS
Pulling away and driving
X If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?, or press it up :or down A.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle.
In this way, the distance you have selected is maintained.
If DISTRONIC PLUS detects that the vehicle infront is driving faster, it accelerates your vehi-
cle, but only up to the speed you have stored.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 40 mph
(60 km/h)
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front R
you switch on the appropriate turn signal
R DISTRONIC PLUS does not detect a danger
of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in front becomes too small.
iWhen changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.
Stopping
GWARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if: R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it
is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress thebrake.
iDepending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in front. The specified minimum distance is
set using the control on the cruise controllever.

Deactivating the HOLD function
GWARNING
When leaving the vehicle, it can still roll awaydespite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply.
R the HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
The HOLD function is deactivated automati-
cally if: R you accelerate and the transmission is in
position Dor R.
R you shift the transmission to position P.
R you depress the brake pedal again with a
certain amount of pressure until ëdis-
appears from the multifunction display.
R you activate DISTRONIC PLUS.
On steep uphill or downhill gradients or if
there is a malfunction, the transmission may
also be automatically shifted into position P.
Permanent all-wheel drive
!
Never tow the vehicle with one axle
raised. This may damage the transfer case. Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground or
be fully raised. Observe the instructions for
towing the vehicle with all wheels in full
contact with the ground.
!When testing the parking brake, operate
the vehicle only briefly (for a maximum of ten seconds) on a brake test dynamometer.
When doing this, turn the SmartKey to posi-
tion 0or 1in the ignition. Failure to do this
can cause damage to the drive train or the brake system.
!A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system.
The all-wheel drive system ensures that all
four wheels are permanently driven. The all-
wheel drive system improves vehicle traction together with ESP ®
and 4ETS if a drive wheel
spins due to insufficient grip.
If a drive wheel spins due to insufficient grip: R Only depress the accelerator pedal as far as
necessary when pulling away.
R Take your foot off the accelerator, slowly,
while the vehicle is in motion.
The permanent all-wheel drive system can
neither reduce the risk of accident nor over-
ride the laws of physics if you fail to adapt
your driving style or if you are inattentive. The
all-wheel drive system cannot take into
account road, weather or traffic conditions.
The all-wheel drive system is only an aid. You
are responsible for maintaining a safe dis-
tance to the vehicle in front, for vehicle speed, for braking in good time and for staying in
lane.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
chains ( Ypage 232). Only in this way can the
maximum effect of all-wheel drive be ach-
ieved.
For information on driving off-road, see the
Digital Operator's Manual.

or increased load on the vehicle, mainte-
nance work must be carried out more fre-
quently, for example: R regular city driving with frequent intermedi-
ate stops
R if the vehicle is primarily used to travel
short distances
R use in mountainous terrain or on poor road
surfaces
R if the engine is often left idling for long peri-
ods
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must
be checked more often. Further information
can be obtained at a qualified specialist work- shop, e.g. an authorized Mercedes-Benz Cen-
ter.
