Driving and pa rking

ATTENTION ASSIST assesses your level of fati-gue or lapses in concentration by taking thefollowing criteria into account:
Ryour personal driving style, e.g. steeringcharacteristics
Rjourney details, e.g. time of day and lengthof journey
The functionality of ATTENTION ASSIST isrestricted and warnings may be delayed or notoccur at all:
Rif the road condition is poor, e.g. if the sur-face is uneven or if there are potholes
Rif there is a strong side wind
Rif you have adopted a sporty driving stylewith high cornering speeds or high rates ofacceleration
Rif you are predominantly driving slower than50 mph (80 km/h) or faster than 112 mph(180 km/h)
Rif you are currently using COMAND or mak-ing a telephone call with it
Rif the time has been set incorrectly
Rin active driving situations, such as whenyou change lanes or change your speed
ATTENTION ASSIST is only an aid to the driver.It might not always recognize fatigue orincreasing inattentiveness in time or fail torecognize them at all. The system is not a sub-stitute for a well-rested and attentive driver.
Warning and display messages in the
multifunction display
XActivate ATTENTION ASSIST using the on-board computer (Ypage 175).
If ATTENTION ASSIST is active, you will bewarned no sooner than 20 minutes afteryour journey has begun. You then hear anintermittent warning tone twice and theATTENTION ASSIST: Take a Break!ATTENTION ASSIST: Take a Break!mes-sage appears in the multifunction display.
XIf necessary, take a break.
XPress thevor8button to confirmthe message.
On long journeys, take regular breaks in goodtime to allow yourself to rest properly. If youdo not take a break and ATTENTION ASSISTstill detects increasing lapses in concentra-tion, you will be warned again after 15 minutesat the earliest.
ATTENTION ASSIST is reset when you continueyour journey and starts assessing your tired-ness again if:
Ryou switch off the engine
Ryou take off your seat belt and open thedriver's door, e.g. for a change of drivers orto take a break
When ATTENTION ASSIST is deactivated, the

Battery acid is caustic. Avoid con-tact with skin, eyes or clothing.
Wear suitable protective clothing,especially gloves, apron and face-guard.
Rinse any acid spills immediatelywith clear water. Contact a physi-cian if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz recom-mends that you only use batteries which havebeen tested and approved for your vehicle byMercedes-Benz. These batteries provideincreased impact protection to prevent vehicleoccupants from suffering acid burns shouldthe battery be damaged in the event of anaccident.
In order for the battery to achieve the maxi-mum possible service life, it must always besufficiently charged.
Like other batteries, the vehicle battery maydischarge over time if you do not use the vehi-cle. In this case, have the battery disconnec-ted at a qualified specialist workshop. You canalso charge the battery with a charger recom-mended by Mercedes-Benz. Contact a quali-fied specialist workshop for further informa-tion.
Have the battery condition of charge checkedmore frequently if you use the vehicle mainlyfor short trips or if you leave it standing idlefor a lengthy period. Consult a qualified spe-cialist workshop if you wish to leave your vehi-cle parked for a long period of time.
Remove the SmartKey if you park the vehicleand do not require any electrical consumers.The vehicle will then use very little energy,thus conserving battery power.
If the power supply has been interrupted, e.g.if you reconnect the battery, you will have to:
Rreset the function for automatically foldingthe exterior mirrors in/out by folding themirrors out once (Ypage 93)
Rset the clock
On vehicles with a multimedia system, thetime is set automatically.
Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is
a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is suffi-
cient ventilation while charging and jump-
starting. Do not lean over a battery.
GWARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
GWARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery,
gases can escape from the battery. There is
a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with a maximumcharging voltage of 14.8V.
!Onlycharge the battery using the jump-starting connection point.
The jump-starting connection point is in theengine compartment.

RMake sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on a battery.
RIt is important that you observe the described order of the battery terminals when connect-
ing and disconnecting a battery.
RWhen jump-starting, make sure that the battery poles with identical polarity are connected.
RIt is particularly important to observe the described order when connecting and disconnect-
ing the jumper cables.
RNever connect or disconnect the battery terminals while the engine is running.
GWARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is a risk of an explo-
sion.
Allow the frozen battery to thaw out before charging it or jump-starting.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could bedamaged by the non-combusted fuel.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the dis-charged battery has frozen. In this case, you may neither charge the battery nor jump-start thevehicle. The service life of a thawed-out battery may be shorter. The starting characteristics canbe impaired, particularly at low temperatures. Have the thawed-out battery checked at a quali-fied specialist workshop.
Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged, theengine can be jump-started from another vehicle or from a donor battery using jumper cables.Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,jump-start the vehicle using a donor battery or a jump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables which have a sufficient cross-section and insulated terminal clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start connectedfor a few minutes before attempting to start. This charges the battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
RThe jumper cables are not damaged.
RBare parts of the terminal clamp do not come into contact with other metal parts while thejumper cables are connected to the battery.
RThe jumper cables cannot come into contact with parts which can move when the engine isrunning, such as the V-belt pulley or the fan.
XSecure the vehicle by applying the electric parking brake.
XShift the transmission to position].
XMake sure that the ignition is switched off. All indicator lamps in the instrument cluster mustbe off. When using the SmartKey, turn the SmartKey to position
