S Sport For standard driving
C Comfort For comfort driving
Press program mode selector
switch1 repeatedly until the letter of
the desired shift program appears in
the tachometer display (
page 22).
SelectCfor comfort driving:
The vehicle starts out in second
gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.
Traction and driving stability are
improved on icy roads.
Upshifts occur earlier even when
you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.
The power transmission ratio for
gear selector lever positionR
changes depending on the program
mode selected (SorC).
Accelerator position
Your driving style influences the
transmission’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
The transmission shifts into a lower
gear.
Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.
!Never change the program mode when
the gear selector lever is out of
positionP. This could result in a
change of driving characteristics for
which you may not be prepared.

In the manual shift program mode you can
change the gears manually on the steering
wheel (
page 161) or by using the gear
selector lever (
page 158).
Allow engine to warm up under low load
use. Do not place full load on the engine
until the operating temperature has been
reached. Shift into reverse gear only when
the vehicle is stopped.Program mode selector switch

Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burn or frostbite on unprotected skin
in the immediate area of the air vents. Al-
ways keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary, change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 177).
iFor draft-free ventilation, move the slid-
ers for the center air vents 1, 7, 9
to the middle position.

Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed.
ABC with vehicle level control systems,
with which you can change vehicle sus-
pension characteristics.
Parktronic system*, which serves as a
parking assistant.
The BAS, ABS and ESP driving systems are
described in the “Safety and Security” sec-
tion (page 77).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume
cruise control at any speed over 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 20).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must remain at all
times responsible for the vehicle speed and
for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Warning!
G
Distronic cannot take street and traffic con-
ditions into account. Only use Distronic if
the road, weather and traffic conditions
make it advisable to travel at a steady
speed.Warning!
G
Use of Distronic can be dangerous on slip-
pery roads. Rapid changes in tire traction
can result in wheel spin and loss of control.
Distronic does not act upon adverse sight
distance conditions. Do not use Distronic
during conditions of fog and heavy rain,
snow or sleet.
Warning!
G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not Distronic is activated.
Use of Distronic can be dangerous on wind-
ing roads or in heavy traffic because condi-
tions do not allow safe driving at a steady
speed.
Distronic will not react to stationary objects
in the roadway (e.g. a stopped vehicle in a
traffic jam or a disabled vehicle). Distronic
will also not respond to oncoming vehicles.
Switch off Distronic:
when changing from the left to the right
lane if vehicles are moving more slowly
in the left lane
when entering a turn lane or highway off
ramp
in complex driving situations, such as in
highway construction zones
In these situations, Distronic will continue to
maintain the set speed unless deactivated.
Distronic is designed and intended only to
maintain a set speed and keep a set dis-
tance from moving objects in front of it.Warning!
G
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Vehicle level control
Your vehicle automatically adjusts its ride
height to
reduce fuel consumption
increase vehicle safety
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:
With increasing speed, ride height is re-
duced by up to approximately 0.95 in
(24 mm).
With decreasing speed, the ride height
is again raised to the selected vehicle
level.Select the level 1 and 2 settings only when
required by current driving conditions.
Otherwise
Fuel consumption may increase
Handling may be impairediThese height adjustments are so small
that you may not notice any change.Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.
272OperationTires and wheelsTire pressure changes by approximately
1.5 psi (0.1 bar) per 18°F (10°C) of air
temperature change. Keep this in mind
when checking tire pressure where the
temperature is different from the outside
temperature.
Tire temperature and tire pressure also in-
crease while driving, depending on the
driving speed and the tire load.Check the spare tire periodically for condi-
tion and inflation pressure. Spare tires will
age and become worn over time even if
never used, and thus should be inspected
and replaced when necessary or after a
maximum of six years.
iThe pressures listed for light loads are
minimum values offering high driving
comfort.
Increased inflation pressures listed for
heavier loads may also be used for light
loads. These higher pressures produce
favorable handling characteristics. The
ride of the vehicle, however, will be
somewhat harder. Never exceed the
max. values or inflate tires below the
min. values listed on the fuel filler flap.
Warning!
G
Follow recommended tire inflation pres-
sures.
Do not overinflate tires. Overinflated tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
274OperationTires and wheels
Activating the tire inflation pressure
monitor
You must activate the tire inflation pres-
sure monitor in the following cases:
If you have changed the tire pressure
If you have replaced the wheels or tires
If you have installed new wheels or
tires
Make sure the tire pressure is correctly
set.
Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display

iIf transporting a deflated road wheel or
additional wheel sensors in the vehicle,
the tire inflation pressure monitor
should not be reactivated until the de-
flated wheel or additional wheel sen-
sors have been removed from the
vehicle. Otherwise, the deflated wheel
or additional sensors could cause the
tire inflation pressure monitor system
to malfunction.
