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 retrieval after an accident or crash event. ED Rs are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED Rs 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. 220 Center
console with ESP
switch
ESP is des igned to help you maintain vehicle control in situations
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 stabilization p rogram. 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 ...

& WA RNING (conti nu ed )
• Plea se be aware th at in ESP offroad mode , particularly on a
s mooth and slippery road, the wheels may have an incr eased
tendency to spin and the vehicle may break awa y -danger of skid ­
ding!
• Stabilit y is limited in the ESP offroad mode. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differe ntia l lock (EDL) helps the ca r to sta rt moving,
acce lerate and climb a gradient on surfaces provi ding poor or almost
no grip. W ithout ED L, th is would be d iff ic ul t, if not impossible .
How the system works
The EDL operates automatically . It mo nitors the rotational speed of
w heels wi th the help of the ABS sensors ==>
page 256 . If a not iceab le
slip is detected at the wheels (e .g . o n slippery g round on one side),
the spin ning whee ls are braked and power is transferred to the other
wheels. This is done up to a speed of about 60 mph ( 100 km/h) .
Noises from the brake system signa l that wheel spin is being
cont rolled.
Driv ing off
W hen d rivi ng off, always be sure to keep road conditions in mind as
you acce lerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of th rottle until t he car starts to move .
Overheating of brakes
To prevent the disc b rake of the bra ked wheel from overhea ting if
subjected to excessive loads on this whee l, t he EDL cuts out tempo ­
ra rily. The vehicle rema ins operat iona l and behaves in the same way
as a veh icle without EDL. As soon as the brake has coo
led down, EDL sw itches on again auto­
m atically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accele rator pedal. Even
with the EDL working , the drive wheels c an 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 risks . Always adapt your d riv ing style to the road
c ondition s and traffic situation.
[ i ] Tips
If a fa ult occurs in the A BS, the ED L is also no t fu nct io ni ng. This is
ind icated by the ABS warn ing light==>
page 19. •
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tion System preven ts the drive n
w heels from spinning when the car is acc ele rating .
General notes
The Anti-S lip Reg ulation Sys tem (ASR) is in tegr ated in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
a tes, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amoun t of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. witho ut the driver 's intervent ion.
With the aid o f th e ABS sensors ==>
page 256, ASR moni to rs the speed
of the driven wheels. If the whee ls start to spin, engine torque is
reduced automatically unt il the tires find enough grip to lock onto
the road s urface. The system is active ac ross the en tire speed range .
