Parking up th
evehicle Problem Possible causes/consequences and
M Solutions
The vehicle is to be left
parked up for longer
than four weeks. The battery may be damaged by heavy discharging.
X
Disconnect the battery (Y page 286)orconnect it to abattery
trickle charger.
i You can obtain more information about battery trickle charg-
ers at aqualified specialist workshop, e.g. aMercedes-Benz
Servic eCentre. The vehicle is to be left
parked up for longer
than six weeks. Damage resulting from non-use may occu
rifthe vehicle is parked
up for long periods.

General driving tips
Rolling with the engine switched off G
Risk of accident
Never switc hthe engin eoff while the vehicle
is in motion.
There is no powe rassistanc efor the steering
and the service brake when the engin eisnot
running.
You will require considerably mor eeffort to
steer and brak eand you could therefore lose
control of the vehicl eand cause an accident. Engine oil
! Vehicle swithadiesel 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. Appl

Important safet ynotes G
Risk of accident
Do not change down for additional engine
brakin gona slipper yroad surface. This could
cause the driv ewheels to lose their grip and
the vehi clec ould skid. G
Risk of accident
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 wit hautomatic transmission,
select shift range 1,2or 3.
i This also applie sifyou have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLU S.
This will use the brakin geffect of th eengine,
so les sbraki ngwill be required to maintain
the speed .This relieves the load on the brake
syste mand prevent sthe brake sfrom ove r-
heati ngand wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously. 154

Aquapla ning If water has accumulated to

on th eroad surface, there is adanger of aqua-
planing occurring, even if:
R you driv eatlow speeds
R thet yres have adequat etread depth
For this reason ,donot drive in tyre ruts ,and
brak ecarefully.
Driving on flooded roads If you have to driv
eonstretches of roadon
whic hwater has collected, please bear in
min dthat:
R the maximu mpermitted dept hins till water
is 25 cm
R you should driv enofaster than at walking
pace.
! Bear in min dthat vehicles travelling in
front or in th eopposite directio ncreate
waves. This ma ycause the maximum per-
missible water depth to be exceeded.
Failure to observe these notes may result
in damage to the engine, electrical systems
and transmission. Winter driving
Important safety notes Have your vehicle winterproofed at
aqualified
specialist workshop, e.g. at aMercedes-Benz
Servic eCentre, at the onset of winter.
Observ ethe notes in the "Changin gawheel"
section (Y page 302). Winter ty
res Us
ew inter tyres at temperatures below
+7 †a nd on sno worice-covered roads .Only
winter tyre sbeari ng the isnowflake sym-
bo lnext to the M+S marking provid ethe best-
possible grip in wintry road conditio ns.O nly
thes etyres will allow the ABS and ESP ®
driv-
ing systems to function optimally in winter, as
thes etyres have been designed specifically
for driving on snow.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with atrea ddepth of less than
4mmm ust be replace dimmediately. They are
no longe rsuitable for winter use and can no
longer provid esufficient grip. This could
cause you to lose control of you rvehicle and
cause an accident.
Alway sobserv ethe maximum permissible
speed specifie dfor the winter tyres you have
fit ted. If you fit winter tyres which have a
lower maximum permissible speed than that
of the vehicle, affix an appropriate warning
sign in the driver' sfield of vision. This can be
obtained at aqualified specialist workshop,
e.g. from aMercedes-Benz Ser vice Centre.
Under these circumstances, you shoul dalso
restrict the maximum speed of the vehicle
using permanen tSPEED-
TRONIC 29
(Y page 17 1)so that it does not
exceed the maximum permissible speed for
the winter tyres.
Onc eyou have fit tedt he winter tyres:
X Chec kthe tyr epressures (Y page 299).
X Restart th etyre pressure los swarning sys-
tem (Y page 301). G
Risk of accident
If you fit the spare wheel when driving with
winter tyres, bear in mind that driving stability
will be impaired due to unstable cornering

You shoul dtherefor eadapt your drivin gstyle
and drive carefully.
Have the spare whee lreplaced at the nearest
qualified specialist workshop which has the
necessar yspecialist knowledge and tools to
carry out the work required. Mercedes- Benz
recommends that you use aMercedes-Benz
Ser vice Centre for thi spurpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at aqualified
specialist workshop.
Snow chains For safety reasons
,Mercedes-Benz recom-
mends that you only use snow chain swhich
hav ebeen speciall yapproved for your vehicle
by Mercedes-Benz ,ora re of acorresponding
standar dofquality.
If you intend to fit snow chains, pleas ebear
the following point sinmind:
R you may not attac hsnow chains to all
wheel-tyre combinations ;see the "Tyres
and wheels" section in the "Techni caldata"
chapter.
R snow chains must not be fitted to emer-
gency spare wheels ,e.g. a"Minispare"
emergency spar ewheel.
R fit snow chains only in pair sand only to the
rear wheels .Observ ethe manufacturer's
installation instructions.
Do not exceed the maximum permissible
speed of 50 km /h.
i You may wish to deactivat eESP®
when
pulling away with snow chains fitted
(Y page 57). This way you can allow the
wheels to spin in acontrolled manner, ach-
ieving an inc reased driving forc e(cutting
actio n).
Slipper yroad surfaces G
Risk of accident
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 particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion ,steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when movin gatlow speed:
X Vehicles with manua ltransmission: engage
neutral.
X Vehicles wit hautomatic transmission: shift
the transmission to position N.
X Try to bring the vehicle under control using
corrective steering.

Sym metrical dipped-beam headlamps If your journey takes you to countries where
vehicle
sare driven on th eopposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. This prevents
oncomin gtraffic from being dazzled.

Cruise control
Import ants afety notes Cruise control maintain
saconstant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhil lgradients ,especially if the
vehicle is laden or towing atrailer, yo umust
shift to alower gear in good tim eorselect
shift range 1,2or 3on vehicles with auto-
matic transmission. By doing so, you will
mak euse of the brakin geffect of th eengine,
which relieves the load on the brake system and prevents the brakes from overheating
and wearing too quickly. 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.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. Yo ucan
store any road spee dabove 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay atten tion 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 brakin gingood time. G
Risk of accident
Do not use cruise control:
R in road and traffic condition swhich do not
allow you to maintain aconstant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Brakin goraccelerating
coul dcause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
