Safety Z

G WARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also lose
control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro-
hibit 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 sec-
ond.
Drive sensibly – save fuel Observe the following tips to save fuel: X
The tires should always be inflated to the rec-
ommended tire pressure. X
Remove unnecessary loads. X
Remove roof racks when they are not needed. 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 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 hilly ter-
rain.
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. Always have
work on the engine carried out at a qualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Benz Center for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at a qualified specialist
workshop.
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 shows you how economical
your driving style is. The ECO display assists you
in achieving the most economical driving style
for the selected settings and prevailing condi-
tions. Your driving style can significantly influ-
ence the vehicle's consumption. Driving tips 161
Driving and parking Z

flammable material. Contact a qualified spe-
cialist workshop immediately if damage is
detected.
! There is a risk of damage to the vehicle if: R
the vehicle becomes stuck, e.g. on a high
curb or an unpaved road R
you drive too fast over an obstacle, e.g. a
curb, a speed bump or a pothole in the road R
a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the loads they are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.
The vehicle is only designed for easily negotiable
off-road terrain and poor road surfaces.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This could result in a reduced
braking effect or in total brake failure and also in
increased wear and tear. The braking charac-
teristics change depending on the material
entering the brakes. Clean the brakes after driv-
ing off-road. If you detect a reduced braking
effect or gri nding
noises, have the brake system
checked in a qualified specialist workshop as
soon as possible. Adapt your driving style to the
different braking characteristics.
Driving off-road increases the likelihood of dam-
age to the vehicle, which, in turn, can lead to
failure of the mechanical assembly or systems.
Adapt your driving style to suit the terrain con-
ditions. Drive carefully. Have damage to the vehicle rectified immediately at a qualified spe-
cialist workshop.
Do not shift into transmission position \\ when
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. 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 181).
The following driving systems are specially
adapted for driving over easily negotiable off-
road terrain: R
Off-road program ( Y
page 181)R
Off-road 4ETS ( Y
page 70)R
Off-road ESP ®
( Y
page 72)R
DSR (Downhill Speed Regulation)
( Y
page 180)
Observe the following notes: R
Stop the vehicle before starting to drive along
an off-road route. If necessary, activate the
off-road program ( Y
page 181).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 295). R
Always keep the engine running and in gear
when driving on a downhill gradient. Activate
DSR ( Y
page 180). 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 rea-
sons, 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.166
Driving tips
Driving and parking

Observe the following rules when driving along
ruts in off-road terrain or on roads with loose
gravel: R
Activate the off-road program ( Y
page 181).R
Avoid high engine speeds. R
Shift to a lower gear using the left-hand steer-
ing wheel paddle shifter. R
Drive slowly. R
Where ruts are too deep, drive with the
wheels of one side on the center grassy area,
if possible.
Traveling uphill
Approach/departure angle
G WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
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 165).R
Follow the line of fall when driving on slopes
and steep inclines. R
Before driving on extreme uphill and downhill
gradients, select the off-road program
( Y
page 181).R
Drive slowly. R
Accelerate gently and make sure that the
wheels are gripping. R
Avoid high engine speeds, except when driv-
ing on sandy and muddy routes with high driv-
ing 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 steering wheel paddle
shifter to shift into a lower gear in good time
on long and steep downhill gradients.
Hill start assist will aid you when pulling away on
a hill. For further information about hill start
assist, see ( Y
page 140).
Do not shift into transmission position \\ when
driving off-road. You could lose control of the vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for
your vehicle, drive back down in reverse gear.
Always observe the approach/departure angle
values ( Y
page 384).
Maximum gradient-climbing capability Always observe the maximum gradient climbing
ability values ( Y
page 384).
Hilltops When driving up an uphill gradient, slightly
reduce pressure on the accelerator immediately
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. Otherwise, the
vehicle could slip sideways, tip and rollover. R
Shift to a lower gear using the left-hand steer-
ing wheel paddle shifter before tackling steep
downhill 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.
Off-road ABS is activated when the off-road pro-
gram is selected.
At speeds below 18 mph (30 km/h), the front
wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces
the stopping distance on off-road terrain. The
steerability of the vehicle is considerably
reduced if the wheels lock.168
Driving tips
Driving and parking

When you change lanes, Distance Pilot
DISTRONIC monitors the left lane (on left-hand-
drive vehicles) or the right lane (on right-hand-
drive vehicles).
Stopping
G WARNING
If you leave the vehicle when it is only being
braked by Distance Pilot DISTRONIC, it could
roll away if: R
there is a malfunction in the system or in
the voltage supply. R
Distance Pilot DISTRONIC is switched off
using 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 are tam-
pered with. R
the battery is disconnected R
the vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the vehicle, always deactivate
Distance Pilot DISTRONIC and secure the
vehicle against rolling away.
Further information on deactivating Distance
Pilot DISTRONIC ( Y
page 176).
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
to a stop.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever. When Distance Pilot DISTRONIC is activated,
the transmission shifts automatically to position
] if: R
the driver's seat belt is not fastened 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.
The electric parking brake secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated when the vehicle is stationary and: R
a system malfunction occurs. R
the power supply is insufficient.
If a malfunction occurs, the transmission may
also be shifted to position ] automatically.
Setting a speed X
Push cruise control lever up C for a higher
speed or down D for a lower speed.X
To adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly push
the cruise control lever up C or down D to
the pressure point.
Every time the cruise control lever is pressed
up C or down D the last speed stored is
increased or reduced. X
To adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly push
the cruise control lever up C or down D
beyond the pressure point.
Every time the cruise control lever is pressed
up C or down D , the last speed stored is
increased or reduced.
i If you accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the
last speed stored after you have finished over-
taking.
Setting a specified minimum distance You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function you can set the minimum distance that
Distance Pilot DISTRONIC maintains to the vehi-
cle in front, depending on vehicle speed. You
can see this distance in the multifunction dis-
play ( Y
page 175).
Make sure that you maintain the minimum dis-
tance to the vehicle in front as required by law.174
