during the journey, stop the vehicle in a
safe place as soon as is possible. Check the
engine oil level. The warning given by the
engine oil warning light must not be
ignored. Continuing your journey when the
symbol is shown may result in engine dam-
age.

top it up if necessary.
Only then does the engine receive enough
oil when the vehicle is standing on a steep
incline.

level
checked at a qualified specialist workshop
(Y page 160).

Driving tipsDriving and parking

PARKTRONIC is an electronic parking aid with
ultrasonic sensors
.Itindicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe manoeuvring, parking and exiting a park-
ing space. Check in front, behind and to the
sides of the vehicle before manoeuvring,
parking or exiting a parking space. There
must not be any persons, animals or objects
in the area in which yo uare manoeuvring.
PARKTRONIC cannot identify any persons or
objects outside of the detection range. As a
result, PARKTRONIC cannot warn you about
objects in this area.
PARKTRONIC is activated automatically if
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors General notes
:
Example: sensors in the front bumper,
left-hand side Side view
Top view
The sensors must be free of dirt, ice and
slush. Otherwise, they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them
(Y
page 298).
Front sensors Centre Approximately 100 cm
Corners Approximately 60 cm
Rear sensors
Centre Approximately 90 cm

If there is an obstacle withi
nthis range, the

Important safety notes
Work on the battery, e.g. removing or instal-
ling, requires specialist knowledge and the
use of special tools. Therefore, always have
work on the battery carried out at a qualified
specialist workshop. G
WARNING
Work carried out incorrectly on the battery
can, for example, lead to a short circuit and
damage your vehicle's electronic system. This
can disrupt driving safety systems such as
ABS (anti-lock braking system) or ESP ®
(Elec-
tronic Stability Program).
R If ABS malfunctions, the wheels can lock
during braking. This limits the steerability
of the vehicle when braking and the braking
distance may increase. There is a risk of
accident.
R If ESP ®
malfunctions, the vehicle will not be
stabilised if it starts to skid or a wheel starts
to spin. There is a risk of accident.
You should therefore have all work involving
the battery carried out at a qualified specialist
workshop. Battery (vehicle)
