2012 MERCEDES-BENZ A CLASS steering wheel

Steering wheel gearshift paddles
:
Left steering wheel gearshift paddle
(shifts down)
; Right steering wheel gearshift paddle
(shifts up)
In drive program M, you can change gear
yourself using the steering wheel gearshift
paddles.
If
you pull the left or right steering wheel gear-
shift paddle when in automatic drive program
E (drive program C on AMG vehicles) or S, the
automatic transmission shifts into drive pro-
gram M for a limited time. Depending on
which gearshift paddle is pulled, the auto-
matic transmission immediately shifts into
the next gear down or up.
AMG vehicles: you can activate drive pro-
gram M RACE START (Y page 181) using the
steering wheel gearshift paddles.
i You can only change gear with the steer-
ing wheel gearshift paddles when the trans-
mission is in position D.
i For further information on the manual
drive program, see ( Y page 156).Automatic drive program
Drive program E (drive program C on AMG
vehicles) is characterised by the following:
R comfort-oriented engine settings.
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner. R
the vehicle pulling away more gently in
forward

and reverse gears unless the accel-
erator pedal is depressed fully.
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example.
R the automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin.
Drive program S is characterised by the fol-
lowing:
R sporty engine settings.
R the automatic transmission shifting up
later.
R as a result of the later automatic transmis-
sion shift points, the fuel consumption pos-
sibly being higher. Manual drive program
Introduction In manual drive program
M, you can change
gear yourself by using the steering wheel
gearshift paddles. For this, the transmission
must be in position D. The gear currently
selected and engaged is shown in the multi-
function display.
Manual drive program M differs from drive
programs E (drive program C on AMG vehi-
cles) and S with regard to spontaneity,
responsiveness and smoothness of gear
changes. Gear Driving situations

i When manual drive program M is activa-
ted via the steering wheel gearshift pad-
dles, the temporarily active manual drive
program M will be deactivated automati-
cally after a limited time, if the driving sit-
uation permits. The automatic transmis-
sion switches to the previously activated
drive program E (drive program C on AMG
vehicles) or S. When driving on downhill
gradients, the temporarily active manual
drive program M

will only be deactivated if
the accelerator pedal is depressed while
the vehicle is rolling downhill. Shifting up X
Pull the right-hand steering wheel gearshift
paddle

(Y page 156).
The automatic transmission shifts up to the
next gear.
i All vehicles (except AMG vehicles): in
order to prevent engine damage the auto-
matic

transmission automatically shifts up:
R if the maximum engine speed on the cur-
rently engaged gear is reached and
R you depress the accelerator pedal.
AMG vehicles:
! In manual gearshift program M, the auto-
matic transmission does not shift up auto-
matically even when the engine limiting
speed for the current gear is reached.
When the engine limiting speed is reached,
the fuel supply is cut to prevent the engine
from overrevving. You must make sure that
the engine speed does not reach the red
area of the rev counter. Otherwise, there is
a risk of engine damage.

hand steering wheel gearshift paddle until
the

transmission selects the optimum gear
for the current speed.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
Kickdown AMG vehicles:
it
is only possible to use kick-
down in temporary manual drive program M.
You can also use kickdown for maximum
acceleration in manual drive program M.
X Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Shift back up once the desired speed is
reached.
i During kickdown, you cannot shift gears
using

the steering wheel gearshift paddles.
i If you apply full throttle, the automatic
transmission shifts up to the next gear
when the maximum engine speed is
reached. This prevents the engine from
overrevving. Deactivating the manual drive program X

Driving and parking

Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (
Y page 320).
Driving with summer tyres Observe the notes in the "Winter operation"
section (
Y page 320).
Slippery road surfaces G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This
increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission:
shift to neutral.
X Vehicles with automatic transmission:
shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially

in wooded areas or on bridges. You
should pay special attention to road condi-
tions when temperatures are around freezing
point.
i For more information on driving with
snow chains, see ( Y page 321). Driving systems
Cruise control
Important safety notes If you fail to adapt your driving style, cruise
control

can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account road,
weather or traffic conditions. Cruise control
is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time, and for staying in the
lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed
(e.g. in heavy traffic or on winding roads).
R on smooth or slippery roads. Braking or
accelerating can cause the drive wheels to
lose traction and the vehicle could then
skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow.
If there is a change of drivers, advise the new
driver of the speed stored.
General notes Cruise control maintains a constant road
speed

for you. It brakes automatically in order
to avoid exceeding the set speed. You must
select a lower gear in good time on long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer. For vehi-
cles with automatic transmission, you need
to have selected manual drive program
M(Y page 156). By doing so, you will make
use of the braking effect of the engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. 168

Parking tips:
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. It may be the case that Active
Parking Assist guides 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 can-
cel the parking procedure with Active Park-
ing 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, the parking
procedure will be cancelled. A sensible
parking

position can no longer be achieved
from this position.
Exiting a parking space In order that Active Parking Assist can sup-
port you when you exit the parking space:
R
the border of the parking space must not
be too low.
R the border of the parking space must not
be too wide. The system manoeuvres the
vehicle

into a position at a maximum of 45°
to the starting position in the parking
space.
R a manoeuvring distance of at least 0.60 m
must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle using Active Parking Assist.
X Start the engine.
X Switch on the turn signal on the side facing
