economical driving. A higher level indicates amore economical driving style. If the threeouter areas are completely filled at the sametime, the driver has adopted the most eco-nomical driving style for the selected settingsand prevailing conditions. The ECO displayborder lights up.
The ECO display does not indicate the actualfuel consumption. The additionally achievedrange displayed underBonus fr. startBonus fr. startdoesnot indicate a fixed consumption reduction.
In addition to driving style, the actual con-sumption is affected by other factors, such as:
Rload
Rtire pressure
Rcold start
Rchoice of route
Ractive electrical consumers
These factors are not included in the ECO dis-play.
An economical driving style specially requiresdriving at moderate engine speeds.
Achieving a higher value in the categories"Acceleration" and "Constant":
Robserve the gearshift recommendations.
Rdrive the vehicle in drive programCorE.
In urban traffic and stop-start traffic, drive pro-gramCis recommended.
On long journeys at a constant speed, e.g. onthe highway, only the outer area for "constant"will change.
The ECO display summarizes the driving stylefrom the start of the journey to its completion.Therefore, there are more marked changes inthe outer areas at the start of a journey. Onlonger journeys, there are fewer changes. Formore marked changes, perform a manual rest(Ypage 171).
Further information on the ECO display(Ypage 170).
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients
!On long, steep gradients, you must reducethe load on the brakes. To use engine brak-ing, shift to a lower gear in good time. Thishelps you to avoid overheating the brakesand wearing them out excessively.
When making use of the engine brakingeffect, it is possible that a drive wheel maynot turn for some time, e.g. in the case ofsuddenly changing or slippery road surfaceconditions. This could cause damage to thedrive train. This type of damage is not cov-ered by the Mercedes-Benz warranty.
Change into a lower gear in good time on longand steep downhill gradients. This is especiallyimportant if the vehicle is laden.
This also applies if you have activated cruisecontrol or Active Distance Assist DISTRONIC.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal
while driving, the braking system can over-
heat. 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 constantlyresults in excessive and premature wear tothe brake pads.
If the brakes have been subjected to a heavyload, do not stop the vehicle immediately, butdrive 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 rainwithout braking, there may be a delayed reac-tion from the brakes when braking for the first
Driving tips139

driving and braking accordingly during thisbreak-in period.
Excessive heavy braking results in correspond-ingly high brake wear. Observe the brake sys-tem warning lamp in the instrument clusterand note any brake status messages in themultifunction display. Especially for high per-formance driving, it is important to maintainand have the brake system checked regularly.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth onthe road surface, there is a danger of hydro-planing occurring.
For this reason, in the event of heavy rain or inconditions 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
!Do not drive through flooded areas. Checkthe depth of any water before drivingthrough it. Drive slowly through standingwater. Otherwise, water could enter thevehicle interior or engine compartment. Itcan then damage the engine's or automatictransmission's electronic components. Itcan also be sucked in by the engine's airintake connection and cause engine dam-age.
Winter driving
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding 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 vehi-
cle becomes trapped in snow. There is a risk
of fatal injury.
If you leave the engine or the auxiliary heat-
ing 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 qualifiedspecialist workshop at the onset of winter.
Drive particularly carefully on slippery roadsurfaces. Avoid sudden acceleration, steeringand braking maneuvers. Do not use cruisecontrol.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
The outside temperature indicator is notdesigned to serve as an ice-warning deviceand is therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especiallyin wooded areas or on bridges. The vehiclecould skid if you fail to adapt your drivingstyle. Always adapt your driving style and driveat a speed to suit the prevailing weather condi-tions.
You should pay special attention to road con-ditions when temperatures are around freezingpoint.
For more information on driving with snowchains, see (Ypage 270).
For more information on driving with summertires, see (Ypage 269).
Observe the notes in the "Winter operation"section (Ypage 269).

Driving systems
Cruise control
General notes
Cruise control maintains a constant roadspeed for you. It brakes automatically in orderto avoid exceeding the set speed. On long andsteep downhill gradients, especially if the vehi-cle is laden, you must select a lower gear ingood time. By doing so, you will make use ofthe braking effect of the engine. This relievesthe load on the brake system and prevents thebrakes from overheating and wearing tooquickly.
Use cruise control only if road and traffic con-ditions make it appropriate to maintain asteady speed for a prolonged period. You canstore any road speed above 20 mph(30 km/h).
Important safety notes
If you fail to adapt your driving style, cruisecontrol can neither reduce the risk of an acci-dent nor override the laws of physics. Cruisecontrol cannot take into account the road,traffic and weather conditions. Cruise controlis 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 inlane.
Do not use cruise control:
Rin road and traffic conditions which do notallow 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 losetraction 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, advise the newdriver of the speed stored.

Storing or calling up a speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate
or brake 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.
