2011 MERCEDES-BENZ B-CLASS HATCHBACK height

You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
WARNING
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured .These
are not taken into account when the parking
procedure is calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assist in such situations. G
WARNING
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation. In some cases the vehicle
will also take you onto sections of the oncom-
ing lane during the parking procedure.
You are responsible for safety at all times and
must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist
parking procedure. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tyres.
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all. R
snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 164) warning messages during the
parking procedure.
R at any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be cancelled.
R when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R never use Active Parking Assist when snow
chains are fitted.
R make sure that the tyre pressures are
always correct.T his hasadirec tinfluence
on the parking characteristics of the vehi-
cle.
R the way your vehicle is positioned in the
parking space after parking is dependent
on various factors .These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. In some cases, Active Parking
Assist may guide you too far into a parking
space, or not far enough into it. In some
cases, it may also lead you across or onto
the kerb. If necessary, you should cancel
the parking procedure with Active Parking
Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
a gear be changed too early to achieve a
sensible parking position, the parking pro-
cedure will be cancelled.
Detecting parking spaces Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 30 km/h, you will see
the parking symbol as a status indicator in the
instrumentc luster. Active Parking Assist only Driving systems

Driving systemsDriving and parking

When towing a trailer, always adjust your
speed to the curren
troad and weather con-
ditions. Do not exceed the maximum permis-
sible speed for your vehicle/trailer combina-
tion. G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
WARNING
On no account should you attempt to draw the
vehicle/trailer combination out by increasing
speed. G
WARNING
If you exceed the maximum noseweight when
using a carrier system on the ball coupling:
R the carrier system may be thrown around.
R the ball coupling and the carrier system
may become detached from the vehicle.
As a result, you may injure others or cause an
accident.
Do not exceed the maximum noseweight.
When driving with a loaded carrier system,
always adjust your driving style to the prevail-
ing road, traffic and weather conditions and
drive particularly carefully.
You can use carrier systems, e.g. bicycle
racks or load-bearing implements, on the ball
coupling. The maximum noseweight of 75kg
applies when using carrier systems on the ball
coupling.
General notes !
Use a drawbar noseweight as close as
possible to the maximum permissible nose-
weight. Do not use a noseweight of less
than 50kg, otherwise the trailer may come
loose. Note that the payload and the rear axle load
are reduced by the actual payload.
X When towing a trailer, set the tyre pressure
on the rear axle of the towing vehicle for a
maximum load; see the tyre pressure table
in the fuel filler flap (Y page 295).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 318).
The maximum noseweight of the trailer draw-
bar on the ball coupling is 75 kg. The actual
noseweight may however not be higher than
the value which is given on the trailer tow
hitch or trailer identification plates. The low-
est weight applies.
Please note that when towing a trailer, PARK-
TRONIC (Y page 163) and Blind Spot Assist
(Y page 177) are only available with limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable draw-
bar.
Driving tips i
Observe the notes on ESP ®
trailer stabi-
lisation (Y page 67).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the max-
imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. Refer to the "Technical
data" section to find out whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing a trailer,
the vehicle/trailer combination may not
exceed a maximum speed of 100 km/h for
reasons concerning the operating permit.
This also applies in countries in which the 182

Important safety notes G
WARNING
An incorrectly secured roof carrier, ski rack or
load could become detached fro mthe vehi-
cle. These objects might then be thrown
around, and could injure you or others or
cause an accident. Follow the roof carrier/ski
rack manufacturer's installation instructions
and special instructions for use.
The roof load raises the vehicle's centre of
gravity, thereby affecting vehicle handling.
You must always observe the maximum roof
load of 75 kg .Always adapt your driving style
to the prevailing road, traffic and weather
conditions and drive with particular care if the
roof is laden.
! Mercedes-Ben zrecommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benzv ehicles.
This helps to preven tdamage to the vehi-
cle.
Positio nthe load on the roof carrier in such
a way that the vehicle will not sustain dam-
age even when it is in motion.
Ensure that, depending on the vehicle's
equipment, you can raise the panorama
sliding sunroof fully and open the tailgate
fully when the roof carrier is fitted. 254

Notes on oil level Depending on your driving style, the vehicle
consumes up to 0.8 l of oil per 1,000 km. The
oil consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
Depending on the engine, the oil dipstick may
be installed at a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement. Engine compartment
263Maintenance and care Z

The following must be observed when raising
the vehicle:
R
to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz.Ifu sed incor-
rectly, the jack could tip over with the vehi-
cle raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suited for per-
forming maintenance work under the vehi-
cle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never disen-
gage the parking brake while the vehicle is
raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, load-bearing underlay must be used.
On a slippery surface, a non-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as a jack underlay.O therwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
R make sure tha tthe distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R never place your hands and feet under the
raised vehicle.
R never lie under the raised vehicle.
R never start the engine when the vehicle is
raised.
R never open or close a door or the tailgate
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. Steel wheel with wheel trim
X Vehicles with steel wheels: carefully
reach into two of the wheel trim openings
and remove the wheel trim. X
