The ..Jwarning/indicator light illuminates for a few seconds after the
ignition is turned on as function check and then goes out .
If the symbol appears, pressure is too low in at least one tire.
When the system detects a ma lfunction, the warning/ind icator light
will flash for approximately one minute and then remain continu­ ously i lluminated. This sequence will continue upon subsequent
vehicle starts up as long as the malfunction exists . Contact your

Intelligent technologyL ______________________________________ _
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 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 sp in is being controlled .
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 pedal
until the car starts to move. The wheel less ab le to transfer power
spms .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily. The
vehicle remains operat ional and behaves in the same way as a vehicle
without EDL .
As soon as the brake has cooled down, EDL switch es on again auto­
matically.
Electronic limited slip differential*
In vehicles w ith front wheel drive*, an electronic lim ited slip differen­
tial engages when driving on curves. The brakes are applied spec ifi­
cally to the front wheel that is on the inside of the curve. This mini­
m izes sliding on the front wheels and enables precise and neutral
driving through curves. The electronic limited slip differential does
not engage when d riving in wet conditions or snow.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL and the ele ctronic limited slip differential working,
the drive wheels can spin and reduce your ability to control your
ca r. -Risk of crash!
& WARNING (continued)
• The increased safety afforded by EDL and the electronic limited
slip differential does not mean that you can take safety risks .
Always adapt your driving style to the road conditions and traffic
situation.
[I) Tips
If a fau lt occurs in the ABS, the EDL is also not f unct ioni ng. This is
indicated by the ABS warning light=>
page 16.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Sl ip Regu lation System (ASR) is integrated in the electronic
stabili zation program (ESP) . When the vehicle starts up and acceler­
ates, the wheels are prevented from sp inning by adjust ing the engine
power to match the amount of grip available from the road surface.
How the system works
ASR performs automatica lly, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 192, ASR monitors the speed
of the driven wheels. If the wheels start to spin, the engine torque is
reduced automatically until the tires find enough grip to lock onto
the road surface. The system is active across the entire speed range.
The ASR works in conjunction with the ABS. If a malfunction shou ld
occur in the ABS, the ASR w ill also be out of action .
[I) Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can .,

Battery diagnosis
Battery diagnosis continuously determines the state of the battery.
Sensors determine battery voltage, battery current and battery
temperature. This determines the current state of charge and the
power of the battery .
Idling current management
Idling current management reduces energy consumption while the
vehicle is standing. With the ignition switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnosis is considered.
Depending on the battery's state of charge , individual consumers are
gradually turned off to prevent excessive discharge of the battery and
thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy management
distributes the energy generated according to the needs of the indi­
v idual components. It regulates consumption, so that more electrical
energy is not being used than is being generated and ensures an
optimal state of charge for the battery.
[ i] Tips
• But even energy management cannot negate the limits of physics.
Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
=> page 196, "Driver notification in the instrument cluster display". •
What you should know
The highest priority is given to maintaining starting capa­
bility.
The battery is severely taxed in short-distance driving, in city traffic
and during the cold time of year. Abundant electrical energy is
Controls and equip­
ment Safety first Vehicle operation
required, but only a little is generated. It is also critical if the engine
is
not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated .
It is in precisely these situations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat adjust ­
ment, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine .
With the engine turned off
If you listen to the radio, for example, with the engine turned off, the
battery is being discharged.
If starting capability is jeopardized due to energy consumption, a
message appears in the driver information display.
You have to start the engine to charge the battery.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
To bring the energy balance back into equilibrium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heating systems in particular require a great deal of
energy . If you notice, for example , that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off. These systems will be available again as soon as
the energy balance has been restored. .,

Some states in the USA require permits to purchase diesel fuel. Check
with your State Motor Vehicle Department.
Diesel fuel may not be available outs ide the USA and Canada. Be sure
to check before traveling to other countries .
Winter operation
At temperatures below 20° F (- 7° C), Diesel fue l No. 2 loses its fluidity
due to wax separation, which may clog the fuel filter or tank filter and
keep the engine from running.
T o help the filter from being clogged by wax, the fuel fi lter in your
vehicle is automatically preheated. Preheating the fuel filter makes
operat ion of your vehicle possib le with Diesel fuel No. 2 down to -
10° F (-24° C).
If you expect temperatures below 5° F (-15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is suffic iently w interized for the
prevailing and expected temperatures.
If not winte rized or insuffic iently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during the
warm-up period in winter.
It is also normal when whitish -blue smoke
comes out of the tailpipe after start ing and during warm-up. The
amount of smoke depends on the outside temperature.
Do not let your diese l engine id le unnecessari ly after a cold start.
Driving off slowly will shorten the warm-up period.
& WARNING
• Never use "starting assist fluids." They may be potentially
explosive or cause a "run-away" engine condition. This could
result in serious engine damage and personal injury.
• Never use fuel line anti-freeze offered for gasoline engines.

0 Note
• Your diesel engine has been specifically designed to operate only
on Ultra Low Sulfur Diesel fue l. Therefore, never use home heating oil
or regu lar gaso line. The properties of these fuels may cause serious
damage to the fuel injection system and to the engine. Using these
fue ls can cause expens ive eng ine repairs and will also adversely affect
your New Vehicle Limited Warranty.
• If diesel fuel should get on any rubber hose, it must be wiped off
immediately. Then wash the contaminated hose portion with soap
and warm water. Do not allow diesel fuel to rema in on connecting
hoses. They may deve lop leaks and cause serious damage. •
