Wet roads
If you have drive
nfor along time in heavy rain
without braking, there may be adelayed reac-
tion from the brakes whe nbraking for the first
time. This may also occur after the vehicl ehas
been washed or drive nthroug hdeep water.
You have to depress the brake pedal more
firmly .Maintain agreater distance from the
vehicl einfront.
After driving on awet road or having the vehi-
cle washed ,brake firmly while paying atten-
tion to the traffic conditions. This wil lwarmup
the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads If you drive on salted roads,
alayer of salt
residue may form on the brake discs and
brake pads. This can result in asignificantly
longe rbraking distance.
R Brake occasionally to remove any possible
sal tresidue. Make sure that you do not
endange rother road users whe ndoing so.
R Carefully depress the brake pedal and the
beginning and end of ajourney.
R Maintain agreater distance to the vehicle
ahead.
Servicing the brakes !
If the red brake warning lamp lights up in
the instrument cluster and you hea rawarn-
ing tone while the engine is running, the
brake fluid leve lmay be too low .Observe
additiona lwarning messages in the multi-
function display.
The brake fluid leve lmay be too low due to
brake pad wea rorleaking brake lines.
Have the brake syste mchecked immedi-
ately. This work should be carrie dout at a
qualified specialist workshop. !
As the ESP ®
syste moperates automati-
cally, the engine and the ignition must be
switched off (the SmartKey must be in posi-
tion 0or 1in the ignition lock or the Start/
Stop button must be in position 0or 1)i f:
R the electric parking brake is tested using
ab rake dynamometer.
R the vehicl eistowed with one axle raised.
Braking triggered automatically by ESP ®
may seriousl ydamage the brake system.
All checks and maintenance work on the
brake syste mmust be carrie dout at aquali-
fied specialist workshop. Have this work car- ried out at an authorized Mercedes-Benz
Center.
Have the brake pad sreplaced and the brake
fluid renewe dataqualified specialist work-
shop, e.g. an authorized Mercedes-Benz
Center.
If the brake syste mhas only been subject to
moderate loads, you should test the function- ality of you rbrakes at regulari ntervals. At a
high speed, brake firmly while paying atten-
tion to the traffic conditions. This improves
the grip of the brake pads.
You can find adescription of Brake Assist
(BAS) on (Y page55).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your
vehicl ewhich have been approved for
Mercedes-Benz vehicles or which correspond to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality coul daffect you rvehi-
cle's operating safety.

becomes trapped in snow. There is
arisk of
fatal injury.
If you leave the engin eorthe auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facin gintot he wind.
At the onset of winter ,have your vehicle win-
terized at aqualified specialist workshop, e.g.
at an authorized Mercedes-Benz Center.
Driv eparticularly carefully on slippery road
surfaces. Avoid sudden acceleration, steering
and brakin gmaneuvers. Do not use cruise
control.
If the vehicle threatens to skid or cannot be
stopped when movin gatlow speed:
X Shift the transmission to position N.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after ashort delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges. You
should pay special attention to road condi-
tion swhen temperatures are around the
freezing point.
For more information on driving with snow
chains, see (Y page 253).
For more information on driving with summer tires, see (Y page 252).
Observe the notes in the "Winter operation"
section (Y page 252). Driving systems
Cruise control
Important safet ynotes Cruise contro
lmaintains aconstan troad
speed for you. It brakes automatically in order
to avoid exceeding the set speed.
On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must select
shift range 1,2or 3in good time
(Y page 127). By doing so, you will make use
of the brakin geffec toft he engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
If you fail to adapt your driving style, cruise
contro lcan neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
contro lcannot take int oaccoun tthe road,
traffic and weather conditions. Cruise control
is only an aid. You are responsible for the dis-
tanc etot he vehicle in front, for vehicle speed,
for brakin gingood time and for staying in
your lane.
Use cruise contro lonly if road and traffic con-
dition smake it appropriate to maintain a
steady speed for aprolonge dperiod. You can
set any road speed above 20 mph (30 km/h).
Do not use cruise control:
R in road and traffic condition swhich do not
allow you to maintain aconstan tspeed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Braking or accel-
eratin gcould cause the drive wheels to lose
traction and the vehicle could then skid
R when ther eispoor visibility, e.g. due to fog,
heavy rain or snow
If ther eisac hangeofd rivers, advise the new
driver of the speed stored. 138

Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visuallya nd
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not areplace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting apark-
ing space. When maneuvering, parking or
pulling out of aparking space, make sure that
there are no persons, animals or objectsin
the area in which you are maneuvering.
! When parking, pay particular attention to
objectsa bove or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objectst hat absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or apneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on uneven terrain.
PARKTRONIC is activated automatically when you:
R switch on the ignition
R Release the electric parking brake.
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h) .Itisreactivated at lower
speeds.
PARKTRONIC monitorst he area around your
vehicle using four sensors in the front bumper
and four sensors in the rear bumper. Driving systems
