Vehicles with

engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or amechanical
componen tofthe engin emanagement system.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. (Y
page 192). The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soo naspossible and allow the engin eand the coolant
to cool down.
X Check the coolant level (Y page261). Observe the warning
notes as you do so and top up the coolan tifnecessary. If the coolan
tlevel is correc t,the radiator fan may be faulty. The
coolant is too hot and the engine is no longe rbeing cooled suffi-
cien tly.
X If the coolant temperature is less than 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Manual transmission

Whe nshifting between 5thand 6thgear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift uninte ntionally into 3rdor4th gear
and damage the transmission. Do not exceed the maximum speed for the
individual gears.
Shiftin
gdown at too high aspeed (trans-
mission braking) can cause the engine to
overrev ,leading to engine damage.
! On long and steep downhill gradients,
especiall yifthe vehicle is laden or towing
at railer, yo umust shift into gear 1, 2or3
in good time. This uses the engine's braking
effect .This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. Neutral

Risk of accident
The movemen tofthe pedals must not be
impaired in any way. Do not keep any objec ts in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
Risk of accident
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. This could cause you
to lose control of your vehicle and cause an
accident. Selector lever

Heav
yand light loads G
Risk of accident
Never depr esst he brake pedal continuously
while the vehicle is in motion ,e.g. never cause
the brakes to rub by applying cons tant slight
pedal pressure. Thi scauses the brake system
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 stop the vehicle immediately ,but
drive on for ashort while. This allow sthe air-
flo wtoc ool the brakes mor equickly.
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 roads If driving in heavy rain for
aprolonged period
of time without braking, there may be a
delayed reaction from th ebrake swhen brak-
ing for the first time. This ma yalso occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain agreater distance from the
vehicl einfront.
After driving on awet road or havin gthe vehi-
cle washed, brake firml ywhile 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 perfo rmance on salt
treated roads G
Risk of accident
The layer of salt on the brake discs and the
brake pads/linings may cause adelay in the
braking effect ,resultin ginas ignifican tlyl on-
ger brakin gdistance, which could lead to an
accident.
To avoid this danger, you should: R
occasionally brake carefully, without put-
ting other road users at risk, when you are
drivin gons alted 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 th evehicle
ahead and driv ewith 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/linin gs G
Risk of accident
New brake pads/lining sonly reach thei ropti-
mum braking effect after severa lhundred 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/lining shave 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 correspond to an equivalent quality
standard. Brake pads/lining swhich hav enot
been approved for Mercedes-Benz vehicles or
which ar enot of an equivalent quality could
affect your vehicle' soperating safety. Ty
re traction G
Risk of accident
Whil ethe vehicle can be fully con trolled at a
cer tain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. Otherwise, you could cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezin gpoint. Driving tips

If thes
econditions ar efulfilled ,your vehicle

ted if changin glanes takes too long or the

Risk of accident
DI ST RONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
The ydon ot relieve you of the responsibility
of payin gattention. The driver remains fully
responsible for the vehicle's distance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.

DISTRONIC PLUS uses additional information
from your navigation system so that it can
react appropriately to certain traffic situa-
tions. This is the case when, following another
vehicle with the help of DISTRONIC PLUS,
you:
R approach or drive through aroundabout
R approach or tur nataTjunction
R turn off at amotorway exit
Even if the vehicle in front leaves the detec-
tion range, DI STRONIC PLUS temporarily
maintains the current driving speed and does
not accelerate. This is base donthe current
ma pd ata in the navigation system. Roundabout (example)
The current spee
dismaintained:
R approximately 10 seconds before reaching
the roundabout/T junction and approx-
imately 1.5 seconds in the roundabout/
after the Tjunction.
R approximately 12 seconds before reaching
am otorway exit and approximately 4sec-
onds after the motorwa yexit
Afterwards ,the vehicle accelerates bac kto
