-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
Infants up to about one year (20 lbs. or 9 kg) are best protected in
special infant carriers and chi ld safety seats designed for t heir age
group. Many experts believe that infants and small childr en should
r ide only in spec ia l restra ints in w hich the child faces the back of the
vehicle. These infant seats support the baby's back, neck and head in
a crash=> fig. 222.
The airbag on the passenger side makes the front seat a potentially
dangerous place for a child to ride. The front seat is not the safest
place for a ch ild in a forward-facing child seat.
It is a very dangerous
place for an infant or a large r child in a rear ward-fac ing seat.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a crash.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat· even with an Advanced Airbag System.
A child will be seriously injured and can be killed when the
inflating airbag hits the child safety seat or infant carrier with
great force and smashes the child safety seat and child against the
backrest, center armrest, door or roof=>
page 208, "Child
restraints on the front seat -some important things to know".
• Always install rear-facing child safety seats or infant carriers
on the rear seat.
• Never install a rear-facing child rest raint in the forward-facing
direction. Such restraints are designed for the special needs of
infants and very small children and cannot protect them properly
if the seat is forward-facing.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and

The vehicle's safety belts alone will not fit most children until
they are at least 4 ft. 9 in. (57 inches/1.45 meters) tall and
weigh about 80 lbs. (36 kg). Booster seats raise these chilÂ
dren up so that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt can help
protect them in a crash.
- Do not use the convertible locking retractor when using
the vehicle's safety belt to restrain a child on a booster
seat.
- Always position the shoulder portion of the safety belt
midway over the child's shoulder. If you must transport an
older child in a booster seat on the front passenger seat,
you can use the safety belt height adjustment to help

& WARNING (cont inued)
• It is safer to install a forward-facing child safety seat on the
rear seat.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>
page 231. Special precauÂ
tions apply when installing a child safety seat on the front
passenger seat=>
page 208, "Child restraints on the front seat -
some important things to know".
& WARNING
Always take special precautions if you must install a forward or rearward-facing child restraint on the front passenger's seat in
exceptional situations:
• Whenever a forward or rearward-facing child restraint is installed on the front passenger seat, the PASSENGER AIR BAG
OFF light must come on and stay on whenever the ignition is
switched on .
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, perform the checks described=>
page 217, "Monitoring
the Advanced Airbag System".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on whenever the ignition is switched
on.
• Improper installation of child restraints can reduce their effecÂ
tiveness or even prevent them from providing any protection .
• An improperly installed child restraint can interfere with the
airbag as it deploys and seriously injure or even kill the child.
• Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier.
• Never place additional items on the seat that can increase the
total weight registered by the weight-sensing mat and can cause
injury in a crash .
& WARNING
Forward-facing child restraints:
• Always make sure the forward -facing seat ha s been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag.
• Never put the forward-facing child restraint up, against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the airbag as possible before installing the forward-facing child
restraint. The backrest must be adjusted to an upright position .
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
& WARNING
Rearward-facing child restraints:
• A child in a rearward-facing child safety seat installed on the
front passenger seat will be seriously injured and can be killed if
the front airbag inflates - even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure on
the weight-mat in the seat and register a heavier weight in the

Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer 's instrucÂ
tions when installing a child restraint in your vehicle. To actiÂ
vate the convertible locking retractor:
- Place the child restraint on a seat, preferably on the rear
seat .
- Slowly pull the belt
all the way out.
- Route it around or through the child restraint belt path
=>& .
- Push the child safety seat down with your full weight to
get the safety belt really tight.
- Insert the belt tongue into the buckle for that seating
position.
- Guide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
Controls and equipÂ
ment Safety first Vehicle operation
-
You should hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pulling on the belt. You should no longer be able to pull
the belt out of the retractor. The convertible lock ing
retractor is now activated.
- Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.
- Pull on the belt to make sure the safety belt is properly
tight and fastened so that the seat cannot move forward
or sideways more than one inch (2.5 cm).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.
• Always buckle the child safety seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a crash.
• Always make sure the seat backrest to which the child restraint
is installed is in an upright position and securely latched into place

acting on the vehicle, the brake pressure and the steering angle are
all meas ured.
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 stabi lized by the forces acting on the whee l during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are main ly applied on the wheel that is on the
outs ide 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 ind icates
when ESP brake application cuts in =>
&.
Th e system operates across the entire speed range in combination
with the ABS system=>
page 256. If the Anti-Lock Brake System
(ABS) malfunctions, the ESP will be out of action as we ll.
Activation
When you turn on the engine, ESP will automatically be activated and
will perform a self-test .
The system can be activated or deactivated by pressing the button
=>
page 252, fig. 234 . The warning light comes on when the system
is switched off=>
page 16.
Normally, the ESP should always be on, however, it may be advantaÂ
geous to turn off the sys tem in certain special cases when some
degree of whee l spin is desired such as:
• when driving with snow chains
• when driving in deep snow or on a loose surface (to allow the
wheels to dig in to reach firm ground)
• when trying to "roc k" the vehicle free when it has become stuck.
The system should be reactivated once you are no longer in such situÂ
ations.
Controls and equip ment Safety first Vehicle operation
Both the ABS and
EDS systems are still functioning even if the ESP is
switched off.
& WARNING
The Electroni c 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,
acce lerate 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 he lp of the ABS sensors
=>
page 256 . 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 other drive whee l 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 contro lled.
Driving 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 with
less grip , gradually increase the pressure on the accelerator peda l

until the car starts to move . The whee l less ab le to transfer power
spins .
Overheating of brakes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads, the EDL cuts out temporarily . The
veh icle remains operat ional and beh aves in the same way as a vehicle
without EDL .
As soon as the brake has coo led down, EDL switches on again autoÂ
matically .
& WARNING
• When a ccelerating on slippery surfaces, such as on ice or snow,
alw ay s be careful when depre ssing the a ccelerator pedal. E ven
with the EDL working, the drive wheel s can spin and reduce your
ability to control your car . Risk of crash !
• The in creased safety afforded by EDL does not mean that you
can take safety ri sks. Always adapt your driving st yle to the road
condition s and traffic situation .
fi Tips
If a fault occurs i n the ABS, the EDL is also no t fu nct ion ing . This is
indicated by the ABS warning light~
page 19. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulati on System prevents the driven
wheels from spinning when the car is a ccel erating.
General notes
T he Anti-S lip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the veh icle starts up and accelerÂ
ates , the wheels are p reve nted from sp inning by adjust ing the eng ine
powe r to match t he amo unt of grip avai lab le from the road s urface.
How the system works
ASR perfo rms au toma tica lly, i .e . witho ut the drive r's in tervent ion .
With the aid of the A BS sensors~
page 256, ASR monitors the speed
of the driven wheels . If the wheels start to spin, the engine powe r is
reduced automat ically u nti l the t ires find enough gr ip to lock onto
the road s urface. The system is active across the entire speed range.
Th e ASR wor ks in con ju nction with the A BS .
If a m alfu nction sho uld
occur in the ABS, the ASR w ill also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety ri sks . Always adapt your driving style to the road
condit ions and traffic situation.
[ i ] Tips
To ensure that the ASR works prope rly, all four wheels must be fitted
w ith ident ic a l ti res Any differences in rollin g radius of the tires can
cause the system to reduce engine power when t his is not desired .
