Drive programs
General notes
You can use the program selector button to
choose between different drive programs for the
automatic transmission. Engine management
and the gearshifting characteristics of the auto-
matic transmission change depending on which
drive program is selected. Thus, a more comfort-
oriented or a more economical driving style is
supported, depending on the wish of the driver.
Selecting drive program Mdeactivates auto-
matic gearshifting, requiring that you change
gear manually.
After the engine is started, the automatic trans-
mission automatically switches to drive pro-
gram C(Comfort) for a comfortable and eco-
nomical driving style.

Driving tips
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rlots of throttle: later upshifts
Kickdown
Use kickdown for maximum acceleration:
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to the next
gear down, depending on the engine speed.
XEase off on the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts up again.
Rocking the vehicle free
At speeds up to 5 mph (9 km/h) you can switch
back and forth between drive position Dand
reverse gear Rwithout applying the brakes. This
helps when rocking the vehicle out of snow or
slush.
XPush the DIRECT SELECT lever alternately up
and down beyond the first point of resistance.
Towing a trailer
XDepending on the downhill gradient, limit the
shift range (Ypage 130) or shift manually into
a lower gear (Ypage 132) in which the engine
will operate in the middle of the engine speed
range. This also applies if cruise control is
activated.
Manual gearshifting
General notes
If you select drive program M, automatic gear-
shifting is deactivated and manual gearshifting
is automatically activated. You must then per-
manently change gear yourself for as long as the
drive program is selected.
Permanent manual gearshifting is deactivated
automatically when you switch from drive pro-
gram Mto another drive program. The auto-
matic transmission then shifts gears automati-
cally. The display shows the selected drive pro-
gram and transmission position Dagain.

General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements of the country in
which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while driving a vehicle.

110 yds (100 m) at a maximum speed of 12 mph(20 km/h).
The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
Driving in wet conditions
Hydroplaning
GWARNING
There is a danger of hydroplaning occurring,
even if you are driving slowly and your tires
have sufficient tread depth, depending on the
depth of water on the road. There is a risk of
an accident.
For this reason, avoid tire ruts and brake care-
fully.
Therefore, in heavy rain or other conditions in
which hydroplaning can occur, drive as follows:
Rreduce your speed
Ravoid tire ruts
Rapply the brakes with care
Driving on flooded roads
!Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
Rthe water level of standing water should not
be above the lower edge of the front bumper
Rdo not drive faster than walking speed
Driving in winter
GWARNING
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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
!An accumulation of snow and ice, particu-
larly when frozen, caught in the area around
the air intake slots, moving parts, the axles
and the wheel arches may:
Rrestrict air intake
Rdamage vehicle parts
Rcause malfunctions by restricting the mobi-
lity intended by the design (e.g. reduced
possible steering input).
Regularly check the vehicle and remove snow
or ice when traveling in wintry conditions.
If there is any damage, inform a qualified spe-
cialist workshop.
!Vehicles with automatic transmission may
roll only briefly in the neutral position N. Pro-
longed rolling of the wheels, e.g. when being
towed, will result in transmission damage.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery roads.
Avoid sudden acceleration, steering and braking
maneuvers. Do not use cruise control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to position N.
XTry to maintain control of the vehicle using
corrective steering.
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 freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. If you do not adjust
your driving style, the vehicle may start to skid.
Al

ways adapt your driving style and drive at a
speed to suit the prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point.

Parking tips:
RThe way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position 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 curb. In this case, cancel the active parking assistance.
RYou can also select transmission position D
prematurely. The vehicle redirects and does
not drive as far into the parking space. If you
change direction too early, parking assis-
tance is canceled and Active Parking Assist is
stopped. It is then not possible to achieve a
sensible parking position from the current
position.
Exiting a parking space
In order that Active Parking Assist can assist you
when exiting the parking space:
Rthe border of the parking space must be high enough at the front and the rear. A curb stone
is too small, for example.
Rthe border of the parking space must not be
too wide. Your vehicle can be maneuvered
into a position at a maximum of 45° to the
starting position in the parking space.
Ra maneuvering distance of at least 3.3 ft
(1.0 m) must be available .
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically when exiting
from the parking space. You are responsible for braking in good time.
