Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieva l after an accident or crash event. ED R's are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED R's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped w ith
a number of electronic control modu les for various vehicle systems
such as, for example, engine function, emission control, as well as for
the airbags and safety belts.
T hese electronic contro l modules also record vehicle-re lated data
during normal vehicle operation for diagnostic and repair purposes .
Th e recording capacity of the e lectronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally recorded over a very limited period of time and stored when a
system fault or other condition is sensed by a control unit. Some of
the data then stored may relate to vehicle speed, direction, braking
as well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment.
Electronic Stabilization Program
(ESP)
General information
The ESP improves the vehicle stability.

Fig. 201 Center

switch
ESP is des igned to help you maintain vehicle control in s ituations
where the car approaches the limits of "grip", especia lly when accel­
erat ing and cornering. ESP reduces the risk of skidd ing and imp roves
stability under all road conditions.
Th e system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDL)
and the Anti-Slip Regulation System (ASR) are integrated in the elec­
tronic stabilizatio n pro gram. In addition to the data provided by
these funct ions, the ESP control unit requires additional measure­
ment data provided by high performance sensors. The rotational
speed of the vehicle about its vertical axis, veh icle acceleration in the ...

--------------------------------------------------' '----'----
fore-and-aft and lateral directions, the brake pressure and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continually
compared with the actual behavior of the vehicle. If the two do not
match, for example , when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate wheel to correct
the problem.
The vehicle is then stabilized by the forces acting on the wheel during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are mainly applied on the wheel that is on the
outside of the curve. In the case of a vehicle that is
understeering
(tendency to slide out of the curve), the brakes are applied at the rear
wheel that is on the inside of the curve. An acoustic signal indicates
when ESP brake application cuts in =>
&.
The system operates across the entire speed range in combination
with the ABS system =>
page 244. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
will perform a self-test . As soon as the test is completed, the system
is in normal operating mode.
You can activate a deactivated ESP or deactivated ESP/ ASR if required
by pressing the=>
page 240, fig. 201 button. When they are acti­
vated, the message
ESP/ASR on appears briefly in the display .
Deactivating
The ESP should normally be activated all the time. If necessary , you
can deactivate Anti-Slip Regulation (ASR) or the Electronic Stabiliza­
tion Program (ESP) by pressing the button =>
page 240, fig. 201.
• Deactivating ASR: Tap the but ton . In certain excep tional situa­
tions (e.g. driving with tire chains) , the Anti-Slip Regulation (ASR) can
be deactivated=>
page 242 . The message ASR off appears in the
display as well.
Controls and equip­ ment Safety first Vehicle operation •
Deactivating ESP/ASR
Press the button for more than 3 seconds .
With the ESP/ASR deactivated, the ESP check light comes on, see
=>
page 14. The message ESP switched off appears in the display as
well.
& WARNING
The Electronic Stabilization Program is nevertheless subject to the laws of physics. It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and traffic conditions. Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDL) helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or almost
no grip . Without EDL, this would be difficult, if not impossible .
How the system works
The EDL operates automatically . It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=>
page 244 . If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power to
the othe r drive wheel or wheels (all-wheel drive). This is done up to a
speed of about 60 mph (100 km/h) . Noises from the brake system
signal that wheel spin is being controlled.

Driv ing off
When driving off, always be sure to keep road conditions in mind as
you acce lerate. If one d rive w heel spins because it is on a surface with
less grip, gradua lly inc rease the press ure on the accelerator pedal
un til the car sta rts to move .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads o n this whee l, t he EDL cuts out tem po­
ra rily. The vehicle rema ins operat iona l a nd be haves in the same way
as a ve hicle wit hout EDL.
As soon as the bra ke has coo le d down , ED L swit ches on again au to­
matically.
& WARNING
• When accelerating on slippery surfaces , such as on i ce or snow ,
alway s be careful when depre ssing the accelerator pedal. Even
with the EDL work ing , the drive wheels can spin and reduce your
ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety ri sks . Always adapt your driving style to the road
conditions and traffic situation.
(I) Tips
If a fa ult occurs i n the ABS, the EDL is also not f unct io ni ng . This is
indic ated by t he A BS war ning ligh t=>
page 17.
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tio n Sy stem preven ts the dr iven
w heels from spin ning w hen t he car is accelerating .
General notes
The Anti-S lip Reg ulation Sys tem (AS R) is in tegr ate d in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
at es, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amount of grip avai lable from the road surface.
How the system works
ASR performs automatically, i.e. witho ut the driver 's intervent ion.
W ith the a id of t he ABS sensors=>
page 244, ASR moni to rs the speed
of the dr iven wheels. If the wheels start to spin , th e engine torque is
redu ced a utomatically unti l the t ires find enou gh gr ip to lock onto
the road surface. T he system is active across the entire speed range .
Th e ASR works in conjunction with the ABS. If a malfunction sho uld
occ ur in th e ABS, th e AS R w ill also be out of action.
Activating
The ESP is automatically activated whe n the engine is started and it
performs a se lf-test. You can act ivate a deact ivate d ASR if required by
press ing the=>
pag e 240, fig. 201 button. Whe n it is act ivated, t he
message
ESP/ASR on appears briefly in t he disp lay. Vehicles with
front-wheel d rive a dea ct iva te d ASR a uto mat icall y re-ac tiva tes i tself
at a speed of 40 mp h (70 km/h) .
Deactivating
You can deact ivate t he ASR if required by pressing t he button (for less
t han 3 se conds) =>
page 240, fig. 2 0 1. Wi th the ASR dea ct ivated, the
ESP check light comes on, see=>
page 14. The message ASR off
appe ars i n the di sp la y as wel l. On vehicles wi th fro nt-whee l dr ive:
deactivation is possible only up to 30 mph (SO km/h) for safety
reas ons. Vehi cles w ith all -w heel drive: the AS R can be deac tivated at
any speed. ..
