Driving tips
General driving tips
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the coun-
try in which you are driving. Some jurisdic-
tions prohibit the driver from using a mobile
phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 ft (approximately 14 m) per
second.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the
recommended tire pressure.
XRemove unnecessary loads.
XRemove roof racks when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly terrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There

Driving and parking

is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with
the manufacturer's specifications. For this
reason, all work on the engine must be carried
out by qualified and authorized Mercedes-
Benz technicians.
The engine settings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Maintenance Booklet.
ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists
you in achieving the most economical driving
style for the selected settings and prevailing
conditions. Your driving style can significantly
influence the vehicle's consumption.
:Acceleration
;Coasting
=Constant
?Additional range achieved
Range ?is shown under Bonus fr. Start
and represents the additional range achieved since the beginning of the journey as a result
of an adapted driving style.
If the fuel level has dropped into the reserve
range, the
Reserve Fuel
display message is
shown instead of range ?in the multifunc-
tion display. The 8warning lamp in the
instrument cluster also lights up
(
Ypage 299).
The ECO display consists of three sections,
with an inner and outer area. The sections
correspond to the following three categories:
:Acceleration (evaluation of all
acceleration processes):
Rthe outer area fills up and the
inner area lights up green: mod-
erate acceleration, especially at
higher speeds
Rthe outer area empties and the
inner area is gray: sporty accel-
eration
;Coasting (evaluation of all decel-
eration processes):
Rthe outer area fills up and the
inner area lights up green: antic-
ipatory driving, keeping your dis-
tance and early release of the
accelerator. The vehicle can
coast without use of the brakes.
Rthe outer area empties and the
inner area is gray: frequent heavy
braking
=Constant (continuous evaluation
over the entire journey):
Rthe outer area fills up and the
inner area lights up green: con-
stant speed and avoidance of
unnecessary acceleration and
deceleration
Rthe outer area empties and the
inner area is gray: fluctuations in
speed
Driving tips177
Driving and parking
Z

The three inner areas display the current driv-
ing style and light up green as a result of a
particularly economical driving style.
Depending on the driving situation, up to two
areas may light up simultaneously.
At the beginning of the journey, the three
outer areas are empty and fill up as a result of
economical driving. A higher level indicates a
more economical driving style. If the three
outer areas are completely filled at the same
time, the driver has adopted the most eco-
nomical driving style for the selected settings and prevailing conditions. The ECO display
border lights up.
The ECO display does not indicate the actual
fuel consumption. The additionally achieved
range displayed under Bonus fr. Start
does not indicate a fixed consumption reduc-
tion.
In addition to driving style, the actual con-
sumption is affected by other factors, such
as:
Rload
Rtire pressure
Rcold start
Rchoice of route
Relectrical consumers switched on
These factors are not included in the ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achieving a higher value in the categories
"Acceleration" and "Constant":
Robserve the gearshift recommendations.
Rdrive in drive program E.
On long journeys at a constant speed, e.g. on the highway, only the outer area for "con-
stant" will change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in the outer areas at the start of a journey. On
longer journeys, there are fewer changes. For
more marked changes, perform a manual rest
(
Ypage 245). For further information on the ECO display,
see (
Ypage 244).
Braking
Important safety notes
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.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shifting
early to a lower gear. This allows you to take
advantage of the engine braking effect and
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road sur-
face. This could cause damage to the drive
train. This type of damage is not covered by
the Mercedes-Benz warranty.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
178Driving tips
Driving and parking

If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately.
Drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm up
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, a layer of salt
residue may form on the brake discs and
brake pads. This can result in a significantly
longer braking distance.
RIn order to prevent any salt build-up, apply
the brakes occasionally while paying atten-
tion to the traffic conditions.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up inthe instrument cluster and
Ryou hear a warning tone while the engine
is running
Observe additional warning messages in
the multifunction display. The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immedi-
ately. Consult a qualified specialist work-
shop to arrange this.
!A function or performance test should
only be carried out on a 2-axle dynamom-
eter. If you wish to operate the vehicle on
such a dynamometer, please consult a
qualified specialist workshop in advance.
You could otherwise damage the drive train
or the brake system.
!The ESP®system operates automatically.
The engine and the ignition must therefore
be switched off (the SmartKey must be in
position 0or 1in the ignition lock or the
Start/Stop button must be in position 0or
1) if the electric parking brake is tested on
a brake dynamometer.
Braking triggered automatically by ESP
®
may cause severe damage to the brake
system.
All checks and maintenance work on the
brake system must be carried out at a quali-
fied specialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the function-
ality of your brakes at regular intervals.
Information on BAS (Brake Assist) (
Ypage 68)
and BAS PLUS (Brake Assist PLUS)
(
Ypage 68).
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake
disks and brake pads/linings:
Rbrake disks that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been
approved by Mercedes-Benz or that are of
an equivalent standard of quality
Other brake disks or brake pads/linings can
compromise the safety of your vehicle.
Driving tips179
Driving and parking
Z

Always replace all brake disks and brake
pads/linings on an axle at the same time.
Always install new brake pads/linings when
replacing brake disks.
The vehicle is equipped with lightweight
brake disks to which the wheel assembly with
rim and threaded connection is matched.
The use of brake disks other than those
approved by Mercedes-Benz can change the
track width and is subject to approval, if appli-cable.
Shock-type loads when handling the brake
disks, such as when changing wheels, can
lead to a reduction in comfort when driving
with lightweight brake disks. Avoid shock-
type loads on the lightweight brake disks,
particularly on the brake plate.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if:
Ryou drive at low speeds.
Rthe tires have adequate tread depth.
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
Rlower your speed.
Ravoid ruts.
Ravoid sudden steering movements.
Rbrake carefully.
Driving on flooded roads
!Bear in mind that vehicles traveling in
front or in the opposite direction create
waves. This may cause 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.
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
Rin the case of standing water, the water
level may be no higher than the lower edge of the vehicle body
Ryou should drive no faster than at a walking
pace
Winter driving
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.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the 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
facing into the wind.
Have your vehicle winter-proofed at a quali-
fied specialist workshop at the onset of win-
ter.
180Driving tips
Driving an d parking

Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steering
and braking maneuvers. Do not use the cruisecontrol or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when 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 a short 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. The
vehicle could skid if you fail to adapt your
driving style. Always adapt your driving style
and drive at a speed to suit the prevailing
weather conditions.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.

Cruise Control
General notes
Cruise control maintains a constant road
speed for you. It brakes automatically in order to avoid exceeding the set speed. Change into
a lower gear in good time on long and steep
downhill gradients. This is especially impor-
tant if the vehicle is laden. By doing so, you
will make use of the braking effect of the
engine. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account the road,
traffic and weather conditions. Cruise control
is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time and for staying in
your lane.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain a constant speed, e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel- erating could 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

Cruise control is activated. The vehicle
automatically maintains the stored speed.
iCruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
Storing the current speed or calling up
the last stored speed
GWARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
