Off-road ABS
An AB
Ssystem specifically suited to off -road
ter rain is activated automatically once th eoff-
road program (Y page 222) is activated.
At speeds below 30 km/h, the front wheels
loc kc yclically durin gbraking .The digging-in
eff ect ac hieved in the process red ucesthe
stopping distanc eonoff-road terrain. This
limits steering capability. BAS (Brak
eAssist)
i Observ ethe "Importan tsafety notes" sec-
tion (Y page 61).
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usua lonce you
releas ethe brake pedal. BA Sisd eactivated. G
WARNING
If BAS has malfunctioned, the braking system
remains available with ful lbrake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and th estopping distance may
increase. BAS PLU
S(Brak eAssist System Plus)
BA SP LUS is only availabl eonvehicles with
DI ST RONIC PLUS.
i Observe the "Important safety notes" sec-
tion (Y page 61).
BAS PLUS assists you in braking during haz-
ardous situations at speeds above 30 km/h
and uses the radar sensor syste mtoevaluate
the traffic situation.
With the hel pofthe radar sensor system ,BAS
PLUS can detect obstacles that are in the path of your vehicl
efor an exte nded period of
time.
At speeds up to approximately 70 km/h ,BAS
PLUS may also detect stationary obstacles,
for example ,stopped or parked vehicles.
Shoul dyou approach an obstacle and BAS
PLU Shas detected arisk of collision, BAS
PLU Scalculates the braking force necessary
to avoid arear-end collision .Should you apply
the brakes forcefully ,BAS PLUS can auto-
matically increase the braking force to alevel
suitabl efor the traffic conditions.
If BA SPLUS demand sparticularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
)a re activate dsimul-
taneously.
X Keep the brake pedal depressed until the
emergenc ybraking situatio nisover.
ABS prevent sthe wheels from locking.
The brakes will wor knormally again if:
R you release the brake pedal.
R ther eisnol onger any danger of arear-end
collision.
R no obstacl eisdetected in front of your
vehicle.
BAS PLU Sisthen deactivated .Ifyou have

In particular, the detection of obstacles can
be impaired if ther eis:

rt/stop function
General notes The ECO start/stop func
tion switches the
engin eoff automatically if th evehicle stops
moving.
The engine star tsautomatically when you pull
away again. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
The ECO start/stop function is activated each
time the engine is switched on. The system is
operational when ECO symbol ¤is shown
in the multifunc tion display.
If the ECO star t/stop func tion is deactivated
(Y page 143), ECO symbol ¤is not
shown. G
WARNING
If the ECO symbol appears in the multifunc-
tion displa ywhen the engin eisswitched off,
the engine was switched off automatically.
However, all vehicle systems remain active. If
you open the door, unfasten your seat belt or
remove your foot from the brake pedal, the
engine will automatically start .The vehicle
ma ybegin moving. There is arisk of accident.
To prevent the vehicle from accidentally pull-
ing away, do not release the brake pedal until
you want to drive on. Do not leave the vehicle until you have
switched off the ignition and secured the vehi-
cle to prevent it from rolling away.
! Always switch the ignition off and take the
key with you when leaving the vehicle.
Automa tice ngine switch-off The ECO start/stop function switches the
engin
eoff automatically in certain situations.
To do this ,the vehicle must brake to astand-
still and the brakes must remain depressed
with the transmission in position Dor N.
The engine is only switched off if:
R the vehicle is at astandstill.
R the outside temperature is withi nthe range
that is suitable for the system.
R the engin eisatnormal operatin gtemper-
ature.
R the set temperature for the vehicle interior
has been reached.
R the batter yissufficiently charged.
R the system detects that the windscreen is
not misted up when the air-conditioning

General driving tips
Coasting with the engine switched off G
WAR
NING
Never switch the engine off whil ethe vehicle
is in motion.
There is no power assista ncef or the service
brake when the engin eisnot run ning.
You will require considerably more effort to
brake and you could therefore los econtrol of
the vehicle and cause an accident. Engine oil
! Vehicles with adiesel particle filter:
If the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur durin gthe automa ticc leaning 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 ever y500 km. Brakes
Important safe tynotes 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. 162

G
WARNING
Make sure tha tother road user sare not
endang ered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing
atrailer,
yo um ust select shift range 1,2or 3in good
time.
i This als oapplies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Heavy and light loads G
WARNING
Never depress the brak epeda lconti nuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by apply ingc onstant slight
pedal pressure. This causes the brake system
to overheat, increases the brakin gdistance
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 road surface 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 protectin gthem against corro-
sion.
Limited braking perfo rmance on salt-
treated roads G
WARNING
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
WARNING
New brak epads/linings only reach their opti-
mum braking effect after several hundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you shoul dcompensate
for the reduced brakin geffect by applying
greate rpressure when braking .This also
applies after the brake discs or the brake
pads/linings hav ebeen replaced.
For safety reasons, Mercedes-Benz recom-
mends that you only have brak epads/linings Driving tips
