General driving tips
Rolling with the engine switched off G
WARNING
Never switch the engin eoff while the vehicle
is in motion.
There is no power assistanc efor the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake, and you could therefor elose
control of the vehicle and cause an accident. 166
Driving tipsDriving and parking

Engine oil
! Vehicles with adiesel particle filter:
If the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This can lead to engine
damage. Therefore, if you frequently drive
short distances, make sure to drive on
motorways or countr yroads for 20 minutes
at least every 500 km. Brakes
Important safet ynotes G
WARNING
Do not change down for additional engine
brakin gonas lippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towin gatrailer,
you must shift to alower gear in good tim eor,
on vehicles with automatic transmission,
select shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the brakin geffect of the engine,
so less brakin gwill be required to maintain
the speed. This relieves the load on the brake
syste mand prevent sthe brake sfrom over-
heatin gand wearing too quickly. Heavy and light loads G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brake storub by applying constan tslight
pedal pressure. This causes the brak esystem
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been subjected to aheavy
load, do not sto pthe vehicle immediately, but
drive on for ashor twhile. This allowst he air-
flow to cool the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet road surface If driving in heavy rain for
aprolonged period
of time without braking, there may be a
delayed reaction from the brakes when brak-
ing for the first time. This may also occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain agreater distance from the
vehicle in front.
After driving on awet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt
treated roads G
WARNING
The layerofs alt on thebrake discs and the
brake pads/linings may caus eadelay in the
brakin geffect, resultin ginasignificantly lon-
ger brakin gdistance, which could lead to an
accident.
To avoid this danger, you should: Driving tips
167Driving and parking
Z

R
occasionally brake carefully, without put-
ting other road users at risk, when you are
driving on salted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain agreater distance to the vehicle
ahead and drive with particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.
New brake pads/linings G
WARNING
New brake pads/linings only reach their opti-
mum braking effect after several hundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you should compensate
for the reduced braking effect by applying
greater pressure when braking. This also
applies after the brake discs or the brake
pads/linings have been replaced.
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle which have been
approved for Mercedes-Benz vehicles or
which correspon dtoanequivalent quality
standard. Brake pads/linings which have not
been approved for Mercedes-Benz vehicles or
which are not of an equivalent quality could
affect your vehicle's operating safety. Tyret
raction G
WARNING
Whereas the vehicle can be fully controlled at
ac ertain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. You could otherwise cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezin gpoint. If ice has formed on the road surface (e.g.
from fog),
athin film of water rapidly forms on
the ice when you brake, considerably reduc-
ing tyre traction. Drive with particular care in
such weather conditions. Driving on wet roads
Aquaplaning If water has accumulated to
acertain depth
on the road surface, there is adanger of aqua-
planing occurring, even if:
R you drive at low speeds
R the tyres have adequate tread depth
For this reason, do not drive in tyre ruts, and
brake carefully.
Driving on flooded roads If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R
the maximum permitted still water depth is
25 cm.
R you should drive no faster than at walking
pace.
! Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam-
age the engine, the electronics or the trans-
mission. Winter driving
General notes G
WARNING
If the vehicle becomes trapped in snow,
ensure that snow is kept away from the
exhaust pipe and from around the vehicle as
long as the engine is running. Otherwise, poi- 168

sonous carbon monoxide (CO) may enter the
vehicle, resulting in loss of consciousness and
even death.
To assure sufficient fresh air ventilation, open
aw indow slightly on the side of the vehicle
not facing the wind.
At the onset of winter, have your vehicle win-
terproofed at aqualified specialist workshop,
e.g. at aMercedes-Benz Service Centre.
Observe the notes in the "Winter operation"
section (Y page 319).
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y
page 319).
Slippery road surfaces G
WARNING
Do not shift down for additional engine brak-
ing on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularlyc arefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: engage
neutral.
X Vehicles with automatic transmission: shift
the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
i For more information on driving with
snow chains, see (Y page 320). Driving systems
Cruise control
Important safety notes Cruise control maintains
aconstant road
speed for you. It brakes automaticallyino rder
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing atrailer, you must
shift to alower gear in good time or select
shift range 1,2or 3on vehicles with auto-
matic transmission. By doing so, you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. You can
store any road speed above 30 km/h. G
WARNING
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
WARNING
Do not use cruise control
R in traffic conditions that do not allow you to
drive at aconstant speed (e.g. heavy traffic Driving systems

cause an accident.
R on slippery roads. The drive wheels may
lose their grip when braking or accelerating
and the vehicle may skid.

brakes automatically in order to avoid
exceeding the set speed. Driving systems
171Driving and parking Z

On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing atrailer,
you must select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effect of the engine, which relieves
the load on the brake system and prevents
the brakes from overheating and wearing too
quickly.
If as lower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to
brake and maintain apreset distance to the
vehicle in front. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
R pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front,e .g. motorcycles, or vehi-
cle sd riving on adifferent line. Therefore,
always pa yattention to traffic conditions even
when DISTRONIC PLU Sisactivated. Other-
wise, yo umay fai ltorecognis edanger sin

WARNING
DISTRONIC PLU Scanno ttake account of road
and traffic conditions .IfDISTRONIC doe snot
recognise or no longer recognises the vehicle
in front,don ot activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to alane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on amotor-
way
DISTRONIC PLUS otherwise maintains the
current speed set by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tancec ontrol may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others.
! You must deactivate the radar sensor sys-
tem in certain countries and near radio
telescope facilities. You will find further
information under "Radar sensor system"
in the index.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 345).
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated

Driving systemsDriving and parking

If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If avehicle is driving
in fron tofyou, DISTRONIC operates in the
speed range between 0km/h and
200 km/h.
Do not use DISTRONIC PLUS while driving on
road swith steep gradients. G
WARNING
DISTRONIC PLUS brakes yourv ehicle up to a
maximum of 4m/s2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
