_&. WARNING
-
Following other vehicles too closely in ­
creases the risk of a crash and serious per­
sonal injury .
- Following other vehicles too closely, par­
ticu larly at higher speeds increases the
risk of coll is ions and serious personal in­
jury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic .
- Always select a speed and distance to
traffic ahead that is safe and appropriate
under the prevailing traff ic, road, weath­
er and lighting conditions.
- Never rely on the distance control fea­
ture of ACC a lone to prevent rear-end col­
lis ions. Always be prepared to b rake and
take evasive act io n to avoid co llisions
and other ac cident situations.
- Never allow the clos ing speed between
yo u a nd other vehicles to be so h igh that
the adaptive cruise control may not be
able to slow your vehicle safe ly . If clos­
ing speed is too high, yo u m ust app ly the
brakes yourself to reduce the risk of a
rear-end crash.
- Always select a greater following dis­
tance to the veh icle ahead on wet roads
than on dry roads.
- Always read and heed the information
and WARNINGS

To decide whether it is necessary to switch
off
the ACC (ACC : Sensor blocked) or if it is only a
temporary condition (ACC functionality limit­
ed) the system will take into cons ideration the
outside temperature and/or the windshield
operat ion.
The ACC sensor is dirty or blocked (e.g. leaves,
snow).
The ACC sensor is located behind the area to
the right of the front license plate . If the ACC
sensor is dirty or blocked, clean the area to re­
store system operat ion.
ACC off: Manual control!
The text message ACC off: Manual control!
appears after the ve hicle has been brought to
a standstill by the adaptive cruise control. In
this case you must depress the brake peda l to
prevent the veh icle from rolling. A warn ing

appears :
- The ACC sensor is d irty . The ACC system is
not react ing, or is not reacting correctly, to
moving vehicles up ahead in your lane of
t ravel.
- There may be very light traffic on and there
is nothing that marks the side of the road
(for examp le, guard ra ils, traffic signs,
trees). As soon as a moving vehicle up ahead
is detected again, ACC becomes active again
and the message disappears.

General information
Appl ies to vehicles: with Horne Link® universal rem ote
control
The Homelink ® feature can learn up to three
radio frequency codes for most current trans ­
mitters used for operating garage doors, es­
tate gates, home or outdoor lighting sys·
tems, and other devices.
You must first program the Homelink ® trans·
mitter before you can use the system
¢ page 162, Programming the HomeLink®
transmitter.
In order to program the Homelink® transmit·
ter for devices utilizing rolling code , a second
person on a ladder who can safe ly reach the
garage door opener motor is recommended.
It is also necessary to locate the "learn" but­
ton on your garage door opener motor . Refer
to the operat ing instruct ions for the opener,
as the location and color of this button may
vary by manufacturer.
You can still use the origina l remote control
for the device at any time.
A WARNING
-
- Never use the Homelink® transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as requ ired by federal safety stand­
ards . Th is includes any garage door open·
er model manufactured before April 1,
1982.
- A garage door opener which cannot de·
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards. Using a garage door
opener without these features increases
risk of serious injury or death.
- For safety reasons never release the
parking brake or start the engine while
anyone is stand ing in front of the vehicle .

226 Intellig ent technol ogy
The vehicle is then stabilized by the forces act­
ing on the whee l during braking. If the vehicle
is
oversteering (rear tends to sk id out of the
turn), the brakes are ma inly 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 as needed on the whee l
that is on the ins ide of the curve or addit ional­
l y on the o ther wheels. An acoustic s ignal indi­
cates when ESC b rake app lication cuts in
¢ A .
The system operates across the entire speed
range in combination with the ABS system
¢ page 229. If the Anti-Lock Brake System
(ABS) malfunctions, the ESC wi ll be out of ac­
tion as well .
Activating
When you turn on the engine, ESC w ill auto­
mat ica lly be act ivated and will perform a se lf­
test. As soon as the test is comp leted, the sys­
tem is in normal operating mode.
Offroad mod e
ESC should normally be ope rated in normal
mode because this ensures maximum vehicle
stability. If necessary, you can act ivate the
ESC offroad mode by pressing the but to n
¢ fig . 232 to obtain maximum traction and
braking ability when driving
off paved roads at
l ow speeds. In ESC offroad mode, the indica­
tor light

b ilization control (E S C): Offr oad . Wa rning !
R estric te d stabilit y
appears br iefly in the dis­
p lay .
The ESC offroad mode can be useful in the fo l­
low ing except ional situations when slip or a
h ighly effective differential locking function is
des irable . Examp les:
- when driving with tire chains,
- when driving in deep snow or on loose
ground,
- when driving on uneven surfaces with the
whee ls severe ly unloaded (articulation), and
- when rocking the vehicle loose after it has
become stuck . When the
unusual situation is past, you
sho uld shift back to the norma l ESC operating
mode by pushing the button again . The mes­
sage
S ta b ilizat ion cont rol (ES C): O n then ap­
pears briefly in the display.
H ill desc ent control
The hill descent control is switched on in ESC
offroad mode . When slowly descending steep
gradients on loose ground or when the axles
are articulated, hill descent control provides ass istance by automatically apply ing the
brakes to keep vehicle speed constant. The ve ­
hicle is also rendered easier to steer by selec­
t ive d istr ibut ion of braking force. Hill descent
control intervenes when:
- the acce lerator pedal is not pressed,
- the vehicle is travelling less than 12 mph
(20 km/h),
- a steep gradient is detected,
- wheel behavior indicates loose ground or
conditions with poor adhesion (e .g. also axle
art iculation).
Hill descent contro l operates both d riving for­
ward and in reverse. Active hill descent con­
tro l is deactivated by pressing the accelerator
pedal until the condit ions for activation al­
ready listed are met again .
A WARNING
--
- The Electronic Stabilization Contro l is
neverthe less s ubject to the laws of phys­
ics. It is part icularly important to pay at­
tention to this fact on wet and slippe ry
roads . It i s therefore important that you
always adapt your dr iving to the cond i­
tion of the road and traffic conditions . Do
not a llow the increased safety provided
by the E lectronic Stabilization Contro l
system to lull you into accepting addi­
tional safety risks .
- Please be aware that in ESC offroad
mode, particularly on a smooth and s lip­
pe ry road, the wheels may have an in­
creased tendency to sp in and the vehicle
may b reak away - dange r of skidding!
~

-Stability is limited in the ESC offroad
mode.
Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels .
General notes
The electronic differentia l lock (EDL) helps the
car to start movi ng, accelerate and climb a
gradient on surfaces providing poor or almost
no grip. Without EDL, this would be difficult,
if not impossible.
H ow the system works
The ED L opera tes automatically. It monitors
the rotat iona l speed of wheels w ith the help
of the ABS sensors¢
page 229. If a noticea­
b le
slip is detected at the wheels (e .g. on slip ­
pery ground
on one side), the spinning 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 s ignal that wheel sp in is being
controlled.
Dri ving off
When driving off, always be sure to keep road
conditions in mind as you accelerate. If one
drive wheel spins because it is on a surface
w ith less gr ip, apply
plenty of throttle until
the car starts to move.
O verheating of br akes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads on this wheel, the EDL cuts out tempo­
rarily . T he vehicle remains operational and be­
haves in the same way as a veh icle w ithout
E DL.
As soon as the brake has cooled down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be carefu l
when depressing the acce le rator pedal.
Int ellig ent technolog y 22 7
Even with the EDL working, the drive
wheels can spin and red uce your ab ility
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 driving style to
the road condit ions and traffic situation .
(D Tips
If a fault occurs in the ABS, the EDL is also
not functioning. This is ind icated by the
ABS warning light¢
page 18.
Anti-Slip Regulation System (ASR )
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating .
General note s
The Anti-Slip Regu lation System (ASR) is inte­
grated in the Electronic Stabilization Control
(ESC). When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning
by adjust ing the engine power to match the

How the sy stem works
ASR performs automat ically, i.e. without the
driver's intervention. With the aid of the ABS
sensors ¢
page 229, ASR monito rs the speed
of the dr iven wheels .
If the wheels start to
spin, engine torque is red uced automat ically
unt il the t ires find enough grip to lock onto
the ro ad surface. The system is active across
the entire speed range.
T he ASR works in conjunction with the ABS. If
a malfunc tion s hou ld occu r in the ABS, the
ASR wi ll also be out of act io n.
A WARNING ~
The increased safety affo rded by ASR does
not mean that you can take safety risks.
A lways adapt your driving sty le to the road
conditions and traffic situation.
