Winter driving
GWARNING
If you shift downonaslipperyr oad surface in
an attempt to increas ethe engine' sbraking
effect, the drive wheels coul dlose their grip.
There is an increased dange rofskidding and
accidents.
Do not shift downf or additionalengine brak-
ing on aslipperyr oad surface.
GDANGER
If the exhaust pip eisblocked or adequate
ventilation is not possible ,poisonousg ases
such as carbo nmonoxide (CO )may enter the
vehicle. This is the case, e.g. if the vehicle
becomest rappedinsnow. There is arisk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pip eand area
around the vehicl eare clearofs now. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicl ethat is not
facing into the wind.
Have you rvehicl ewinter-proofed at aqualified
specialist worksho patthe onset of winter.
Drive particularly carefully on slipperyr oad sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use the cruis econ-
trol or DISTRONIC PLUS.
If the vehicl ethreatens to skid or cannot be
stoppedw hen moving at low speed:
XShift 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 freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded area soronbridges. The vehicl ecould
skid if you fail to adapt you rdriving style .Always
adapt you rdriving style and drive at aspeedt o
sui tthe prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point. For more information on driving with snow
chains, see (
Ypag
e319).
For more information on driving with summer
tires, see (
Ypag e318).
Observe the notes i
n the "Winter operation" sec-
tion (Ypag e318).

Mercedes-Benz Intelligent Drive stands for inno-
vative drive rassistance and safety systems
which enhance comfort and support the drive rin
critical situations. With these intelligent co-ordi-
nated systems Mercedes-Benz has set amile-
stone on the path towards autonomous driving.
Mercedes-Benz Intelligent Drive embraces all
elements of active and passive safety in one well
though tout syste m–for the safety of the vehi-
cle occupants and that of other road users.

Cruise control
General notes
Cruise control maintains aconstant road speed
for you .Itbrakes automatically in order to avoid
exceeding the set speed. Change into alower
gearing ood time on long and steep downhill
gradients. This is especially important if the
vehicl eisladen. By doing so, you wil lmake use
of the braking effect of the engine. This relieves
the loa donthe brake syste mand prevents the
brakes from overheating and wearing too
quickly.
Use cruis econtrol only if road and traffic con-
ditions make it appropriate to maintain asteady
speedf orap rolonged period. You can store any
road speeda bove 20 mph (30 km/h).
Important safety notes
If you fail to adapt you rdriving style ,cruis econ-
trol can neither reduce the risk of an accident
nor override the law sofphysics. Cruise control
cannot take into account the road ,traffic and
weather conditions. Cruise control is only an
aid .You are responsiblef or the distance to the

AIRMATIC
General notes
AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-round
level control ensures the best possible suspen-
sion and constant ground clearance, even with a
laden vehicle. When you drive fast, the vehicle is
lowered automaticallytoi mprove driving safety
and to reduce fuel consumption. There is also
the option to manuallya djust the vehicle level.
AIRMATIC consists of level setting, level control
and ADS (Adaptive Damping System).
The vehicle level can be set using the DYNAMIC
SELECT switch (
Ypage 139) or the level button
(Ypage 172). The setting always corresponds
to the last selected function.
Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is arisk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
iIf one of the doors is open, the vehicle is not
lowered.

PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors.Itm onitors the area around
your vehicle using six sensors in the front
bumper and six sensors in the rear bumper.
PARKTRONIC indicates visually and audibly the
distanc ebetween your vehicle and an object.
PARKTRONIC is only an aid. It is not areplace-
ment for your attention to your immediate sur-
roundings. You are alwaysr esponsible for safe
maneuvering, parking and exitin gaparking
space. When maneuvering, parking or pulling
out of aparking space, make sure that there are
no persons, animals or object sinthe area in
which you are maneuvering.
!When parking, pay particular attention to
object sabove or below the sensors,s uch as
flower pots or trailer drawbars. PARKTRONIC
does not detect such object swhen they are in
the immediate vicinityoft he vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
object sthat absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on atruck
or ap neumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.

RDo not exceed the maximum permissible
speed of 31 mph (50 km/h).
ROn vehicles with AIRMATIC, you must drive at
raised vehicle level if snow chains have been
installed (
Ypage 172).
RWhen snow chains are installed, never use
Active Parking Assist (Ypage 177).
You may wish to deactivate ESP®when pulling
away with snow chains installed:
RAll vehicles (except Mercedes ‑AMG vehicles)
(Ypage 67)
RMercedes‑AM Gvehicles (Ypage 68)
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv- ing force (cuttin gaction).

Important safety notes
GWARNING
Underinflated or overinflated tires pose the
following risks:
Rthe tires may burst, especially as the load
and vehicle speed increase.
Rthe tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
Rthe driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
Rmonthly, at least
Rif the load changes
Rbefore beginning along journey
Runder different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Information
placard and tire pressure table shown here are
examples. Tire pressure specifications are vehi-
cle-specific and may deviate from the data
shown here. The tire pressure specifications
that are valid for your vehicle can be found on
the Tire and Loading Information placard and
tire pressure table on the vehicle.
