Protecting the environment
General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affec-
ted by these factors:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel
consumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer
need them.
Ra regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal
when starting the engine.
Rdo not warm up the engine when the vehi-
cle is stationary.
Rdrive carefully and maintain a safe dis-
tance from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each
gear only up to

Driving safety systems
Overview of driving safety systems
In this section, you will find information aboutthe following driving safety systems:
RABS (Anti-lockBrakingSystem)(Ypage 60)
RBAS (BrakeAssistSystem) (Ypage 61)
RActive Brake Assist (Ypage 61)
RESP®(ElectronicStabilityProgram)(Ypage 63)
REBD (ElectronicBrake forceDistribution)(Ypage 67)
RADAPTIVE BRAKE (Ypage 67)
RSTEER CONTROL (Ypage 67)
Important safety notes
If you fail to adapt your driving style or if youare inattentive, the driving safety systems canneither reduce the risk of an accident noroverride the laws of physics. Driving safetysystems are merely aids designed to assistdriving.
You are responsible for maintaining the dis-tance to the vehicle in front, for vehicle speed,for braking in good time, and for staying inlane. Always adapt your driving style to suitthe prevailing road and weather conditions andmaintain a safe distance from the vehicle infront. Drive carefully.
The driving safety systems described onlywork as effectively as possible when there isadequate contact between the tires and theroad surface. Please pay special attention tothe notes on tires, recommended minimumtire tread depths, etc. (Ypage 305).
In wintry driving conditions, always use wintertires (M+S tires) and if necessary, snowchains. Only in this way will the driving safetysystems described in this section work aseffectively as possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a waythat the wheels do not lock when you brake.
This allows you to continue steering the vehi-cle when braking.
The%ABS warning lamp in the instrumentcluster lights up when the ignition is switchedon. It goes out when the engine is running.
ABS works from a speed of about 5 mph(8 km/h), regardless of road-surface condi-tions. ABS works on slippery surfaces, evenwhen you only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
GWARNING
If ABS is malfunctioning, the wheels could
lock when braking. The steerability and
braking characteristics would be severely
affected. There is an increased danger of
skidding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,including driving safety systems, will alsobecome inoperative. Observe the informationon the ABS warning lamp (Ypage 233) anddisplay messages which may be shown in theinstrument cluster (Ypage 204).
Braking
XIf ABS intervenes:continue to depress thebrake pedal vigorously until the braking sit-uation is over.
XTo make a full brake application:depressthe brake pedal with full force.
If ABS intervenes when braking, you will feel apulsing in the brake pedal.
The pulsating brake pedal can be an indicationof hazardous road conditions, and functions asa reminder to take extra care while driving.
Off-road ABS
An ABS system specifically suited to off-roadterrain is activated automatically once the off-road program is activated (Ypage 170).
At speeds below 20 mph (30 km/h), the frontwheels lock cyclically during braking. The dig-ging-in effect achieved in the process reduces

Situation-dependent braking assis-
tance
General information
iObserve the "Important safety notes" sec-tion (Ypage 60).
With the help of the radar sensor system,Active Brake Assist can detect obstacles thatare in the path of your vehicle for an extendedperiod of time.
If Active Brake Assist detects a risk of collisionwith the vehicle in front, it calculates the brakepressure necessary to avoid a collision. If youapply the brakes forcefully, situation-depend-ent braking assistance adapts to the situationand automatically increases the brake pres-sure to a degree appropriate to the traffic sit-uation.
Situation-dependent braking assistance pro-vides braking assistance in hazardous situa-tions at speeds above 4 mph (7 km/h). It usesradar sensor technology to assess the trafficsituation.
Situation-dependent braking assistance iscapable of reacting to moving objects thathave already been detected as such at leastonce over the period of observation, up tovehicle speeds of around 155 mph(250 km/h).
Situation-dependent braking assistance canalso detect stationary objects, up to vehiclespeeds of around 44 mph (70 km/h).
XKeep the brake pedal depressed until theemergency braking situation is over.ABS prevents the wheels from locking.
The brakes will work normally again if:
Ryou release the brake pedal
Rthere is no longer any danger of a collision
Rno obstacle is detected in front of your vehi-cle
Situation-dependent braking assistance is thendeactivated.
Important safety notes
iObserve the "Important safety notes" sec-tion for driving safety systems (Ypage 60).
GWARNING
Active Brake Assist does not react:
Rto persons, bicycles, motorcycles or ani-
mals
Rto approaching vehicles
Rto cross traffic
Ron bends
As a result, Active Brake Assist cannot inter-
vene in all critical situations. There is a risk
of an accident.
Always pay careful attention to the traffic
situation and be prepared to brake.
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist might:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake. Terminate
the intervention in a non-critical driving sit-
uation.
Due to the nature of the system, complex butnon-critical driving conditions may also causeActive Brake Assist to intervene.
Even if Active Brake Assist is not available dueto a malfunction in the radar sensor system,the brake system is still available with fullbrake boosting effect and BAS.
ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
ESP®monitors driving stability and traction,i.e. power transmission between the tires andthe road surface.
If ESP®detects that the vehicle is deviatingfrom the direction desired by the driver, one ormore wheels are braked to stabilize the vehi-
