When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is a malfunction
in the system, it may not be possible to apply the released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it roll- ing away.
X Shift the automatic transmission to posi-
tion P.
It may not be possible to release an applied
parking brake if the on-board voltage is low or there is a malfunction in the system. Contact
a qualified specialist workshop.

General notes
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. G
WARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicleis stationary.
Observe the legal requirements for the coun- try in which you are driving. Some jurisdic-
tions prohibit the driver from using a mobile
phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 ft (approximately 14 m) per
second. 162
Driving tipsDriving and parking

Drive sensibly – save fuel
Observe the following tips to save fuel:
R The tires should always be inflated to the
recommended tire pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not nee-
ded.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly terrain.
Drinking and driving G
WARNING
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 G
WARNING
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 components in exhaust fumes within legal limits. These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, only have work on the engine carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Maintenance Booklet. ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and prevailing conditions. Your
driving style can significantly influence the
vehicle's consumption. Example: ECO display
The ECO display consists of three bars:
R Acceleration
Acceleration
R Constant Constant
R Coasting
Coasting
The percent value is the average value of the three bars. The three bars and the mean value
begin at the value of 50%. A higher percent-
age indicates a more economical driving
style.
The ECO display does not indicate the actual fuel consumption. A fixed percentage count
in the ECO display does not indicate a fixed
consumption. Driving tips
163Driving and pa rking Z

to failure of the mechanical assembly or sys-
tems. Adapt your driving style to suit the ter- rain conditions. Drive carefully. Have damage
to the vehicle rectified immediately at a quali- fied specialist workshop.
Do not switch to transmission position N
when driving off-road. If you try to brake the
vehicle using the service brake, you could
lose control of the vehicle. If the gradient is
too steep for your vehicle, drive back down in
reverse gear.
General notes H
Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Read this section carefully before driving your
vehicle off-road.
Off-road driving is only possible with the Off-
Road Engineering package (Y page 186).
The following driving systems are specially
adapted for driving over easily negotiable off-
road terrain:
R Off-road program (Y page 186)
R Off-road ABS (Y page 65)
R Off-road 4ETS (Y page 69)
R Off-road ESP ®
(Y page 72)
R DSR (Downhill Speed Regulation)
(Y page 184)
Observe the following notes:
R Stop the vehicle before starting to drive
along an off-road route. If necessary, acti-
vate the off-road program (Y page 186).
R To avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
R Check that items of luggage and loads are
stowed safely and are well secured
(Y page 271).
R Always keep the engine running and in gear
when driving on a downhill gradient. Acti-
vate DSR (Y page 184). R
Drive slowly and evenly, if necessary at a
walking pace.
R Ensure that the wheels are in contact with
the ground at all times.
R Drive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R Check the depth of water before fording
rivers and streams.
R Watch out for obstacles.
R Take care when turning on an uphill or
downhill slope or when driving across a
slope. The vehicle could otherwise tip over.
R Always keep the side windows and the pan-
orama roof with power tilt/sliding panel
closed during the journey.
R Do not deviate from marked routes.
i Do not use the HOLD function when driv-
ing off-road, on steep uphill or downhill gra- dients or on slippery or loose surfaces. The
HOLD function cannot hold the vehicle on
such surfaces.
Checklist before driving off-road X
Engine oil level: check the engine oil level
and add oil if necessary.
When driving on steep gradients, the
engine oil level must be sufficiently high to
ensure a correct oil supply in the vehicle.
X Wheels and tires: check the tire tread
depth and tire pressure.
X Check for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tires.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
X Rims: dented or bent rims can result in a
loss of tire pressure and damage the tire
bead. Therefore, check your rims before
driving off-road and replace them as
required. Driving

could slip sideways, tip and rollover. There is a
risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
R Observe the warnings for off-road driving
(Y page 168).
R Follow the line of fall when driving on slopes
and steep inclines.
R Before driving on extreme uphill and down-
hill gradients, select the off-road program
(Y page 186).
R Drive slowly.
R Accelerate gently and make sure that the
wheels are gripping.
R Avoid high engine speeds, except when
driving on sandy and muddy routes with
high driving resistance.
R Use the left-hand steering wheel paddle
shifter to shift to a lower gear appropriate
to the gradient.
R Use the left-hand paddle shifter to shift into
a lower gear in good time on long and steep
downhill gradients.
i Hill start assist will aid you when pulling
away on a hill.
For further information about hill start
assist, see (Y page 144).
Do not switch to transmission position N
when driving off-road. If you try to brake the
vehicle using the service brake, you could
lose control of the vehicle. If the gradient is
too steep for your vehicle, drive back down in reverse gear.
Always observe the approach/departure
angle values (Y page 369).
Maximum gradient-climbing capability Always observe the maximum gradient climb-
ing ability values (Y page 369). Hilltops When driving up an uphill gradient, slightly
reduce pressure on the accelerator immedi-
ately before reaching the brow of the hill.
Make use of the vehicle's own impetus to
travel over the brow.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of a hill
R the vehicle from traveling too quickly down
the other side
Driving downhill R
Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight. Oth- erwise, the vehicle could slip sideways, tip
and rollover.
R Shift to a lower gear using the left-hand
paddle shifter before tackling steep down-
hill gradients.
R Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line
of fall.
R Check that the brakes are working normally
after a long downhill stretch.
i Off-road ABS is activated when the off-
road program is selected.
At speeds below 18 mph (30 km/h), the
front wheels lock cyclically during braking.
The digging-in effect achieved in the proc-
ess reduces the stopping distance on off-
road terrain. The steerability of the vehicle
is considerably reduced if the wheels lock. Driving tips
171Driving and parking Z

If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
The vehicle is only accelerated up to the
speed you have stored.
Selecting the drive program
DISTRONIC Plus supports a sporty driving
style when you have selected the S or M driv- ing program (Y page 152). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have
selected the E driving program, the vehicle
accelerates more gently. This setting is rec-
ommended in stop-and-start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC PLUS supports you when:
R you are driving faster than 43.5 mph
(70 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.
Stopping G
WARNING
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.
For further information on deactivating DIS-
TRONIC PLUS (Y page 178).
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 the
brake.
i After a time, the electric parking brake
secures the vehicle and relieves the service brake.
i Depending 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 control
lever.
The electric parking brake automatically
secures the vehicle if DISTRONIC PLUS is
activated and:
R the seat belt is unfastened and the driver's
door is open.
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function.
R a system malfunction occurs.
R the power supply is not sufficient.
If a malfunction occurs, then the transmission may be shifted into position Pautomatically.
Setting a speed Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to the speed set. Driving systems
