2011 MERCEDES-BENZ C-CLASS COUPE tyre pressure

Permanent SPEEDTRONIC
You can use the on-board computer to limit
the speed permanently to avalue between
160 km/h (e.g. for driving on winter tyres)
and the maximum speed ( Ypage 225).
Shortly before the store dspeed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active,
even if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). Dynamic handling package with
sports mode
General notes The most important part of the dynamic han-
dling package with sports mode is the adjust-
able suspension system. This automatically
controls and adapts the suspension to the
respective driving situation.
The calibration of the suspension depends
on:
R
your driving style
R the road surface conditions
R your individual selection; see the following
description
If your vehicle is equipped with automatic
transmission, the dynamic handling package
with sports mode also includes steering
wheel gearshift paddles (Y page 148) with a
manual drive program (Y page 150). Example: position of dynamic handling package
with sports mode button

Start the engine.
Sports tuning The firmer setting of the suspension tuning in
sports mode ensures even better contact
with the road. Select this mode when employ-
ing a sporty driving style, e.g. on winding
country roads.
Your selection remains stored until you
switch off the engine.

might therefore issue steering instructions
too soon. This may lead to a collision. For this
reason, you should avoid using Parking Guid-
ance in such situations. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Use Parking Guidance for parking spaces:
R that are parallel to the directio noftravel
R that are on straight roads, not bends
R that are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat kerbs
Parking tips:
R on narrow roads, drive pastt he parking
space as close as possible.
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 181) warning messages during the
parking procedure.
R when transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
R never use Parking Guidance with snow
chains or an emergency spare wheel fitted.
R make sure that the tyre pressures are
always correct.T his hasadirec teffect on
the steering instructions.
R the way you rvehicle is positioned in the
parking space after parkin gis 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, Parking Guidance
may guide you too far or not far enough into
a parking space. In some cases, it may also lead you across or onto the kerb. If neces-
sary, cancel the parking procedure with
Parking Guidance.
! 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.
Detecting parking spaces Example: vehicles with automatic transmission
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Parking Guidance is automatically activated
when you drive 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
parking symbol ;as a status indicator in the
instrument cluster.
When a parking space has been detected, an
arrow towards the right =or the left :also
appears. Parking Guidance only displays
parking spaces on the front-passenger side
as standard. Parking spaces on the driver's
side are displayed as soon as the turn signal
on the driver's side is activated. To park on
the driver's side, you must leave the driver's
side turn signal switched on until you have
engaged reverse gear. 184

Visual and acoustic collision warning
If you switch on the appropriate turn signals
to change lanes, and a vehicle is detected in
the side monitoring range of Active Blind Spot
Assist, you will receive a visual and acoustic
collision warning .You will then hear a double
warning tone, and red warning lamp :
flashes. If the turn signal remains on, detec-
ted vehicles are indicated by the flashing of
red warning lamp :. There are no further
warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is designed to help you avoid a col-
lision.
The course-correcting brake application is
available in the range between 30 km/ha nd
200 km/h.
If a course-correcting brake application
occurs, red warning lamp :flashes in the
exterio rmirro rand the following is shown in
the multifunctio ndisplay, for example: Example: vehicles with automatic transmission
G
WARNING
Active Blind Spot Assist is only an aid
designed to assist driving. It is not a substitute
for attentive driving. Automatic braking by the
system may not always be sufficien tto avoid
a collision. In such cases, you need to steer,
brake or accelerate yourself.
In very rare cases, the system may detect a
risk of collision where there is none and brake
in error near crash barriers or similar road
boundaries. Active Blind Spot Assist cannot
detect all traffic situations and road users.
Ensure at all times that there is sufficient lat- eral distance between you and other road
users or obstacles. You can, for example,
countersteer gently or depress the accelera-
tor pedal at any time to cancel inappropriate
braking action.
You are responsible for the vehicle's speed,
correc
tsteering and for braking in good time.
Always adap tyour driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle.
R a vehicle approaches too closely on the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you brake or accelerate decisively.
R a driving safety system intervenes, such as
ESP ®
or PRE-SAFE ®
Brake.
R ESP ®
is deactivated.
R a loss of tyre pressure or a defective tyre is
detected.
Activating Active Blind Spot Assist
X On vehicles without a navigation system,
make sure that the Becker ®
MAP PILOT is

Trailer towing
If you attach a trailer, make sure you have
correctly established the electrical connec-
tion. This can be accomplished by checking
the trailer lighting. Trailer towing

Important safety notes G
WARNING
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully .If
you do no tcouple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section. Trailer towing

WARNING
If the Check trailer hitch locking mechanism message appears in the multi-
function display while the vehicle is in motion,
pull over immediately and check whethe rthe
ball coupling is correctly engaged. G
WARNING
Always observe the maximum speed permit-
ted in Germany for vehicle/trailer combina-
tions, even in countries where higher speeds
are permitted. This lowers the risk of an acci-
dent. 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.
General information i
When towing a trailer, set the tyre pres-
sure on the rear axle of the towing vehicle
for a maximum load; see the tyre pressure
table in the fuel filler flap (Y page 339).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 361).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg.
However, the actual noseweight must not
exceed the value given on the trailer tow hitch
and trailer identification plates. The lowest
weight applies.
! Use a noseweight as close as possible to
the maximum permissible noseweight. Do
not use a noseweight of less than 50 kg,
otherwise the trailer may come loose. Bear in mind that the payload and the rear
axle load are reduced by the actual nose-
weight.
Please note that when towing a trailer, PARK-
TRONIC (Y page 179), parking guidance
(Y page 183) and Blind Spot Assist
(Y page 190) 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 70).
In Germany, the maximum permissible speed
for vehicle/trailer combinations depends on
the type of trailer, and is either 80 km/h or
100 km/h. In some countries, higher maxi-
mum speeds are permissible for vehicle/
trailer combinations. Before beginning the
journey, check the trailer's documents to see
what the maximum permitted speed is.
For certain Mercedes-Ben zvehicles, 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
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be differen tincomparison
to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance 200
