Drive sensibly –save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to the rec-
ommended tire pressure.
RRemove unnecessary loads.
RWarm up the engin eatlow engin espeeds.
RAvoid frequenta cceleration or braking.
RObserve the servicei ntervals in the Mainte-
nanc eBooklet or in the servicei nterval dis-play. Have all the maintenanc
ework carried in
accordance with Daimler AG regulations.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinkin gand driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of aserious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engin erunning in enclosed spaces with-
out sufficientv entilation.
Certain engin esystems are designed to keep
the level of poisonous component sinexhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .Always have
work on the engin ecarried out at aqualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
BenzC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aqualified specialist
workshop.
The engin esettings must not be changed under
any circumstances. Furthermore, all specific
servicew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Benzs ervicer equirements. Details can be found
in the Maintenance Booklet.

Parking Guidance
Important safety notes
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. Asuitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You can also still use Active Parking
Assist PARKTRONIC (
Ypage 149).
Parking Guidance is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that there are no per-
sons, animals or object sinthe maneuvering
area when you are maneuvering or parking.
GWARNING
If object sare located above or below the
detection range, Active Parking Assist may
steer too early. This could cause acollision.
There is arisk of an accident.
Do not use Active Parking Assist in these
types of situation.
!If they cannot be avoided, drive over obsta-
cles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the
wheels or tires.
If Active Parking Assist PARKTRONIC is deacti-
vated, Parking Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Use Parking Guidance for parking spaces:
Rparalleltot he direction of travel
Ron straight roads, not bends
Rthat are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs
