driving 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.
Evenasmall amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility ofaserious or even fatal
accident are 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
taking drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
isarisk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without 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, only have work on the engine 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-Benzservice requirements. Details
can be found in the Maintenance Booklet.

drivingstyle in termsofconsumption,taking
the actual and selected conditionsinto
consideration.Your driving style can
significantly influence the vehicle's
consumption.
The ECO display consistsofthree bars:
RAcceleration
RConstant
RCoasting
The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%.Ahigher
percentage indicatesamoreeconomical
driving style.
The ECO display doesnot indicate the actual
fuelconsumption andafixedpercentage
count in the ECO display doesnot indicate a
fixedconsumption figure.
Apart from driving style, consumption is
dependent on many factors such as,e.g.:
Rload
Rcheck
Rcoldstart
Rchoice of route
Relectrical consumers switched on
These factors are not taken into
consideration by the ECO display.
The evaluation of your driving styleiscarried
outusing the following three categories:
RAcceleration(evaluation of all
acceleration processes):
-The bar fills up: moderate acceleration,
especially at higher speeds
-The bar empties: sporty acceleration
RConstant(assessment of driving behavior
at all times):
-The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
-The bar empties: fluctuations in speed
RCoasting(assessment of all deceleration
processes):
-The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
-The bar empties: frequent braking
iAn economical driving style specially
requires driving at moderate engine
speeds.
To achieveahigher value in the categories
AccelerationandConstant:
Robserve the gearshift recommendations.
Rdrive in drive programE.
iOn long journeys ataconstant speed, e.g.
on the highway, only the bar forConstant
will change.
iThe ECO displaysummaries the driving
characteristics from the start of the journey
to its completion. For this reason, the bars
change dynamically at the beginning of the
journey. On longer journeys, there are
fewer changes. For more dynamic changes,
carry outamanual reset.

Servicing the brakes
!If the red brake warning lamp lights up in
the instrumentcluster and you hear a
warningtonewhile the engine is running,
the brakefluid level may be too low.
Observe additional warningmessages in
the multifunction display.
The brakefluid level may be too low due to
brakepad wear or leakingbrakelines.
Have the brakesystem checked
immediately. This work should be carried
out ataqualified specialist workshop.

Rtherecommended brakefluid is notused
Safe braking can no longer be guaranteed.
AMG high-performance and ceramic
brakes
The high-performance brake system is
installed only on the CLS 63 AMG.
The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:
RSpeed
RBraking force
REnvironmental conditions, such as
temperature and humidity
The wear of individualcomponentsofthe
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.
For this reason, it is impossibletostate a
mileage that will be valid under all
circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information aboutthis from your authorized
Mercedes-BenzCenter.
Driving tips173
Driving and parking
Z

New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. Keep this in mind, and
adapt yourdriving and braking accordingly
during this break-in period.
Excessive heavy braking results in
correspondingly high brake wear. Observe
thebrake wearwarning lamp in the
instrumentcluster and noteany brakestatus
messages in the multifunction display.
Especially for high performancedriving, it is
importanttomaintain and have the brake
system checked regularly.
Driving on wet roads
Hydroplaning
If water has accumulated toacertain depth
on the road surface, there isadanger of
hydroplaning occurring, even if:
Ryou drive at low speeds.
Rthe tires have adequate tread depth.
For this reason,inthe eventofheavy rain or
in conditions in which hydroplaning may
occur, you must drive in the following
manner:
Rlower your speed.
Ravoid ruts.
Rbrakecarefully.
Driving on flooded roads
!Do not drive through floodedareas.
Check the depthofany water beforedriving
through it. Drive slowly through standing
water.Otherwise, water mayenterthe
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.
Winter driving
Important safety notes
GWARNING
If you shift down onaslippery 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
braking onaslippery 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 isarisk 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
awindow on the side of the vehicle that is not
facing into the wind.
Have your vehicle winterproofed ataqualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (Ypage 336).
Driving with summer tires
Observe the notes in the "Winter operation"
section (Ypage 336).
Slippery road surfaces
GWARNING
If you shift down onaslippery 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
braking onaslippery road surface.
174Driving tips
Driving and parking

If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to positionN.
Drive particularly carefully on slippery road
surfaces.Avoid sudden acceleration, steering
and braking maneuvers. Do not use the cruise
control or DISTRONIC PLUS.
iFor more information on driving with
snow chains, see (Ypage337).
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitablefor that purpose.
Changes in the outside temperature are
displayed afterashort 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 areasoronbridges. The
vehiclecouldskid if you fail to adapt your
driving style.Always adapt your drivingstyle
and drive ataspeed to suit the prevailing
weatherconditions.
You should pay special attention to road
conditions when temperatures are around
freezingpoint.
Driving systems
Cruise control
Important safety notes
Cruise control maintainsaconstant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1,2or3in good time. By doing so, you will
make use of the braking effect of the engine.
This relieves the load on the brake system and
preventsthe brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed foraprolonged period. You can
store any road speed above 20 mph
(30 km/h).
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an
accident 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 distance 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 maintainaconstant speed e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Brakingor
accelerating 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
If there isachange of drivers, advise the new
driver of the speed stored.
