General information
Applies to vehicles: with Home link® universal remote
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 157, Programming the Homelink ®
transmitter.
In order to program the Home link ® 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. I t is also necessary to locate the "learn" but
ton on your garage door opener motor . Refer
to the operating instructions 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 .
.&_ 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 federa l 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, signa ling the door to stop
and reverse does not mee t current feder
al safety s tandards. Using a garage doo r
opener without these features increases
risk of serious inj ury or death.
- F or sa fety reasons never release the
parking brake or start the engine w hile
anyone is stand ing in front of the vehicle . -
A garage door or an estate gate may
sometimes be set in mot ion when the
Homelink ® remote control is being pro
grammed. If the device is repeatedly ac
tivated, this can overstrain motor and
damage its e lectr ical components -an

220 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 223. 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 . 218 to obtain maximum traction and
braking ability when driving
off paved roads at
l ow speeds. In ESC offroad mode, the indica
tor light
fi illuminates and the message Off
road control Warning! Red uced t ract ion
ap
pears briefly in the display .
The ESC offroad mode can be usefu l in the fo l
low ing except iona l situations when slip or a
h ighly effective differentia l locking function is
desirable . Examples:
- when driving with tire chains,
- when driving in deep snow or on loose
ground,
- when driving on uneven surfaces with the
wheels severe ly unloaded (articulation), and
- when rocking the vehicle loose after it has
become stuck.
When the unusua l situat ion is past, you
should shift back to the normal ESC operating mode by pushing the button again
. The mes
sage
S tabilit y prog ram on then appears brief
l y in the display.
H ill descent control
T he hill descent con trol is swi tched on in ESC
offroad mode . When slowly descending steep
gradients on loose gro und or when the axles
are articulated, hill descent control provides
ass istance by automatically applying 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 . H ill 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 . a lso axle
articu lation).
Hill descent con tro l operates both d riving for
ward and in reverse. Active hill descent con
trol is deactivated by pressing the accelerator
pedal unti l the conditions for activation al
ready listed are met again.
A WARNING
- The Electronic Stability Control is never
theless subject to the laws of phys ics. It
is part icu larly important to pay attention
to this fact on wet and slippery roads. It is therefore impo rtant that you a lways
a dapt your d riving to the condit ion of the
road and traffic cond itions. Do not allow
the increased safety provided by the Electron ic Stability Control system to lull
you into accepting additional safety
risks.
- Please be aware that in ESC offroad
mode, particularly on a smooth and s lip
pery road, the wheels may have an in
creased tendency to spin and the vehicle
may break away - danger 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.
G ener al note s
The electronic differentia l lock (EDL) helps the
car to start mov ing, accelerate and climb a
gradient on surfaces providing poor or almost
no gr ip . W ithout EDL, this would be difficult,
if not impossible .
How the s yst em work s
The EDL operates automatically . It monitors
the rotat ional speed of wheels w ith the help
of the ABS sensors <=>
page 223. If a noticea
ble
slip i s detected at the wheels (e.g . on slip
pery ground
on one side), the spinning wheels
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 b rake system signal that wheel spin is being
contro lled .
Driving off
When driv ing off , a lways be sure to keep road
conditions in mind as you accelerate . If one
drive whee l spins because it is on a surface
with less grip, apply
plenty of throttle until
the car starts to move.
Overheating of brakes
To prevent the disc brake of the b raked wheel
from ove rheating if subjected to excessive
l oads on this whee l, the EDL cuts out tempo
ra rily. The vehicle remains operational and be
h aves in the same way as a vehicle without
EDL.
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 careful
when depressing the acce lerator pedal.
Even with the EDL working, the drive
wheels can spin and reduce your ability
to control your car . R isk of crash!
Int ellig ent technolog y 221
-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 .
(!) 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.
G eneral not es
The Anti-Slip Regulation System (ASR) is inte
grated in the Electronic Stability Control
(ESC). When the vehicle starts up and acceler
ates, the wheels are prevented from spinning
by adjust ing the eng ine power to match the
amount of grip available from the road sur
face .
How the system works
ASR performs automatica lly, i.e. without the
driver 's intervention. With the aid of the ABS
sensors <=>
page 223, ASR monitors the speed
of the dr iven wheels. If the wheels start to
spin, engine torque is reduced automatically
unt il the t ires find enough grip to lock onto
the road surface. The system is active across
the enti re speed range.
The ASR works in conjunction with the ABS. If
a malfunction should occur in the ABS, the
ASR wi ll also be ou t of act ion.
A WARNING
The increased safety affo rded by ASR does
not mean that you can take sa fety risks.
A lways adapt your driving sty le to the road
conditions and traffic situation. ...,
