Windshield wipers
Switching the windshield wiper
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratch the windshield.
For this reason, you should always switch off
the windshield wipers in dry weather.

Regulating climate control automati-
cally
General notes
When dual-zone automatic climate control is in
automatic mode, the set temperature is auto-
matically kept constant. The system automati-
cally regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode will achieve optimal operation
if the cooling with air dehumidification function
is also activated. If desired, the cooling with air
dehumidification function can be deactivated
(
Ypage 114).
Dual-zone automatic climate control
Automatic mode for automatic climate control
settings can only be activated or deactivated on
the first menu level. If you do not set a new value
for the rear-compartment climate control in the second menu level within approx. ten seconds,
the control panel display goes back to the first
menu level.

Hill start assist
Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. Hill
start assist automatically maintains the brake
pressure for about another second, after you
have taken your foot off the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
Ryou are pulling away on a level road or a
downhill gradient
Rthe transmission is in position N
Rthe parking brake is applied
RESP®is malfunctioning
Reverse warning device
GWARNING
Other road users may ignore or fail to hear the warning tone of the reverse warning feature.
There is a risk of injury if you fail to ensure that
the area in which you are maneuvering is
clear.
Make sure that there are no persons or
objects in the area in which you are maneu-
vering. It may be necessary to enlist the help
of a second person when maneuvering.
The reverse warning feature is a system
designed to assist you in ensuring the safety of
other road users.
A warning signal sounds to alert other road
users when reverse gear is engaged. The volume
of the warning tone can be reduced for night-
time driving.
XTo reduce the volume of the warning tone:
engage reverse gear twice in quick succes-
sion.
The warning tone is now quieter.
iThe warning tone sounds at a normal vol-
ume by default. The volume of the warning
tone has to be reduced each time you engage
reverse gear if necessary.
ECO start/stop function
General notes
When the ECO start/stop function is opera-
tional, it switches the engine off automatically if
the vehicle is slowed to a stop under certain
conditions.
When pulling away again, it starts the engine
automatically. The ECO start/stop function
thereby helps you to reduce the fuel consump-
tion and emissions of your vehicle.
The stop/start function is automatically activa-
ted each time you start the engine with the key.
In drive program Mthe ECO start/stop function
is automatically deactivated. You can manually
activate the ECO start/stop function if required.

Driving and parking
Z

!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive
on for a short while. The brakes are cooled down
more quickly in the airflow.
Wet road surfaces
If you have been driving for a long time in heavy
rain without braking, there may be a delayed
response when you first apply the brakes. This
may also occur after driving through a car wash
or deep water.
You must depress the brake pedal more firmly.
Maintain a longer distance to the vehicle in
front.
While paying attention to the traffic conditions,
you should brake the vehicle firmly after driving
on a wet road surface or through a car wash. This
heats the brake discs, so that they dry more
quickly, which protects them against corrosion.
Limited braking performance on salt-
treated roads
When driving on salted roads, salt may start to
build up on the brake disks and brake pads. This can increase braking distances considerably.
Maintain a greater distance to the vehicle in
front.
To remove any build-up of salt that may have
formed:
XApply the brakes at the start of the journey,
occasionally during journey and at the end of
the journey. Make sure that you do not endan-
ger other road users when doing so.
Checking the brake pad thickness
In addition to monitoring using the brake pad
wear sensor, regularly monitor and check all of
the brake pads by performing a visual inspection
to look for pad material wear.
If you are unable to check the brake wear on the
inside of the wheels, remove the wheels with the tools provided.
Make sure that the brake pad material thickness
never falls below 0.12 in (3 mm). Have the brake pads checked and replaced at a qualified spe-
cialist workshop, if necessary. Do not solely rely on the brake pad wear sensor.
It is strongly recommended that you have the
brake pads checked at a qualified specialist
workshop at every service displayed in the main-
tenance interval indicator, prior to long journeys
and whenever the wheels are removed.
New brake discs and brake pads/
linings
New brake pads and brake discs only reach their
optimal braking effect after about 60 miles
(100 kilometers). Until then, compensate for
this by applying greater force to the brake pedal.
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake discs
and brake pads/linings:
Rbrake discs that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been approved
by Mercedes-Benz or are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake discs or brake pads/
linings on an axle at the same time and only have
them replaced at a qualified specialist work-
shop. When replacing the brake discs, always
have the brake pads/linings replaced at the
same time.
Parking brake
GWARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
When driving on wet roads or dirt-covered sur-
faces, road salt and/or dirt may get into the
parking brake. This causes corrosion and a
reduction of braking force.
In order to prevent this, drive with the parking
brake lightly applied from time to time. When
doing so, drive for a distance of approximately
140Driving tips
Driving and parking

110 yds (100 m) at a maximum speed of 12 mph(20 km/h).
The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
Driving in wet conditions
Hydroplaning
GWARNING
There is a danger of hydroplaning occurring,
even if you are driving slowly and your tires
have sufficient tread depth, depending on the
depth of water on the road. There is a risk of
an accident.
For this reason, avoid tire ruts and brake care-
fully.
Therefore, in heavy rain or other conditions in
which hydroplaning can occur, drive as follows:
Rreduce your speed
Ravoid tire ruts
Rapply the brakes with care
Driving on flooded roads
!Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
Rthe water level of standing water should not
be above the lower edge of the front bumper
Rdo not drive faster than walking speed
Driving in winter
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
!An accumulation of snow and ice, particu-
larly when frozen, caught in the area around
the air intake slots, moving parts, the axles
and the wheel arches may:
Rrestrict air intake
Rdamage vehicle parts
Rcause malfunctions by restricting the mobi-
lity intended by the design (e.g. reduced
possible steering input).
Regularly check the vehicle and remove snow
or ice when traveling in wintry conditions.
If there is any damage, inform a qualified spe-
cialist workshop.
!Vehicles with automatic transmission may
roll only briefly in the neutral position N. Pro-
longed rolling of the wheels, e.g. when being
towed, will result in transmission damage.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and braking
maneuvers. Do not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
XTry to maintain control of the vehicle using
corrective steering.
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 a short 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 areas or on bridges. If you do not adjust
your driving style, the vehicle may start to skid.
Al

ways adapt your driving style and drive at a
speed to suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

securely stowed or lashed down
(
Ypage 244).
RBefore driving off-road, stop the vehicle and
shift to a low gear.
RIf the surface requires, temporarily deactivate
ESP®when pulling away (Ypage 66).
ROnly drive off-road with the engine running
and a gear engaged.
RDrive slowly and smoothly. Walking pace is
necessary in many situations.
RAvoid spinning the drive wheels.
RMake sure that the wheels always remain in
contact with the ground.
RDrive with extreme care over unknown terrain
where you can only see for a short distance.
As a precaution, get out of the vehicle to take
a look at the route to be taken in advance.
RCheck the water depth before fording.
RWatch out for obstacles (e.g. rocks, holes,
tree stumps and ruts).
RAvoid edges where the surface could crumble
or break away.
Checklist after driving off-road
!If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
Off-road driving places a higher demand on your
vehicle than normal road operation. Check your
vehicle after driving on rough terrain. By doing
so you will notice any damage in good time and
reduce the risk of an accident for yourself and
other road users. Clean your vehicle thoroughly
before driving on public roads.
Observe the following points after driving off-
road, on construction sites and before driving on
public roads:
XActivate ESP®(Ypage 66).
XClean the headlamps and tail lamps and
check them for damage.
XClean the front and rear license plates.
XClean the windshield, windows and exterior
mirrors.
XClean the steps, door sills and grab handles.
This increases safety of footing.
XClean the wheels/tires, wheel housings and
the underbody of the vehicle with a water jet. This increases road grip, especially on wet
road surfaces.
XCheck the wheels/tires and wheel housings
for trapped foreign objects and remove them.
Trapped foreign objects can damage the
wheels/tires and may be flung out from the
vehicle when you continue driving.
XCheck the underbody for trapped branches or
other parts of plants and remove them.
Trapped branches or other parts of plants
increase the risk of fire and can cause dam-
age to fuel lines, brake hoses and the rubber
bellows of axle joints and drive shafts.
XClean the brake disks, brake pads and axle
joints, particularly after operation in sand,
mud, grit/gravel, water or similarly dirty con-
ditions.
XCheck the entire floor assembly, the tires,
wheels, bodywork structure, brakes, steering,
chassis and exhaust system for any damage.
XCheck the service brake for operating safety,
e.g. carry out a brake test.
XIf you notice strong vibrations after driving off-
road, check the wheels and drive train for for- eign objects again. Remove any foreign
objects which can lead to imbalances and
thus cause vibrations.
Driving in mountainous areas
When driving in mountainous areas, note that
the power output of the engine, and with it its
gradient climbing capability, decrease with
increasing altitude. Please take note of this par-
ticularly when driving with a trailer in mountain-ous areas.
The maximum permissible trailer loads are valid
for journeys at altitudes up to 1100 yds
(1000 m) above sea level with gradients up to
12%.
Information on maximum permissible trailer
loads can be found in your vehicle registration
papers and on the vehicle identification plate
(
Ypage 305) or under "Trailer loads"
(Ypage 316).

Cruise control
General notes
Cruise control maintains the speed of the vehi-
cle for you. It brakes automatically in order to
avoid exceeding the set speed.
Use cruise control if road and traffic conditions
make it appropriate to maintain a steady speed
for a prolonged period. You can set any speed
from 30 km/h upwards in increments of 1 km/h
and 10 km/h.
If you have set Miles
as the unit for the digital
speedometer, you can set any speed above
20 mph in increments of 1 mph and 5 mph.
Changing the display unit for the digital speed-
ometer and the distance:
Ron vehicles without steering wheel buttons
(Ypage 177)
Ron vehicles with steering wheel buttons
(Ypage 188)
Cruise control should not be activated when
driving off-road or on construction sites.
Cruise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed if the uphill gradient evens out
and the vehicle's speed does not fall below
20 mph (30 km/ h). Cruise control maintains the
stored speed on downhill gradients by automat-
ically applying the brakes. Observe the addi-
tional driving tips (
Ypage 139).
Important safety notes
Observe the notes on braking (Ypage 139).
If you fail to adapt your driving style or if you are inattentive, cruise control can neither reduce
the risk of an accident nor override the laws of
physics. Cruise control cannot take road,
weather and traffic conditions into account.
Cruise control is only an aid. You are responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in lane. If you change wheel size, make sure they corre-
spond to the correct wheel size category
(
Ypage 279). If the category is changed without
recoding the control units in the vehicle, the
functioning of cruise control may be impaired.
Do not use cruise control:
Rin traffic conditions that are unsuitable for
driving at a constant speed, e.g. in heavy traf-
fic, on winding roads or off-road.
Ron slippery roads. Braking or accelerating
may cause the drive wheels to lose traction
and the vehicle could then skid.
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow.
If there is a change of drivers, make sure that
you inform the new driver about the set cruise
speed.
