Indicator and warning lamps
The concept
Indicator and warning lamps can light up in a
variety of combinations and colors.
Several of the lamps are checked for proper
functioning and light up temporarily when the
engine is started or the ignition is switched on.
Text messages
Text messages at the top edge of the Control
Display describe the meanings of the indicator
and warning lamps.
Supplementary text messages
You can call up more information on the Control
Display, e.g. on the cause of a malfunction and
on how to respond, via Check Control, refer to
page77.In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.
Indicator lamps without text messages

* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.

Radio readiness and ignition off
All indicator and warning lamps as well as dis-
plays in the instrument cluster go out.
Starting the engine
Do not run the engine in enclosed areas;
otherwise, the inhalation of toxic exhaust
gases can cause loss of consciousness and
death. The exhaust gases contain carbon mon-
oxide, an odorless and colorless, but highly
toxic gas. Never leave an unattended vehicle
with the engine running; otherwise, such a vehi-
cle represents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in neutral or move the
selector lever to position P and forcefully apply
the parking brake to prevent the car from mov-
ing.<
Avoid frequent starting in quick succes-
sion as well as repeated start attempts in
which the engine does not start. Otherwise, the
fuel is not burned or incompletely burned and
there is a danger of overheating and damaging
the catalytic converter.<
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.
Manual transmission
Remote control in the ignition lock or, with
Comfort Access, inside the vehicle, refer to
page34.
1.Depress the brake.
2.Depress the clutch and shift to neutral posi-
tion.
3.Press the start/stop button.The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Automatic transmission
Remote control in the ignition lock or, with
Comfort Access, inside the vehicle, refer to

1.Depress the brake.
2.Move the selector lever to position P.
3.Press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Diesel engine
When the engine is cold and temperatures are
below approx. 327/06, the starting process
may take a little more time due to automatic
preheating. The preheating indicator lamp in
the instrument cluster comes on; at the same
time a message appears on the Control Display.
Switching off the engine
Always take the remote control with you
when you leave the vehicle.
When parking, apply the parking brake force-
fully; otherwise, the vehicle could begin to roll.<
Manual transmission
1.With the car at a standstill, press the start/
stop button.
2.Shift into first gear or reverse.
3.Forcefully apply the parking brake.
4.Removing the remote control from the igni-
tion lock, refer to page54.

tion lock, refer to page54.
Parking brake
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Indicator lamp
The indicator lamp is lit, and when you
drive off an acoustic signal sounds in
addition. The parking brake is still
applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
In exceptional cases, if the parking brake
has to be used to slow or stop the car, do
not pull the lever up too hard. In doing so, con-
tinuously press the button of the parking brake
lever.
Otherwise, excessive force on the parking
brake can lock up the rear wheels and cause the
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the parking
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.The brake lamps do not light up when the park-
ing brake is applied.<
Manual transmission
When shifting into 5th or 6th gear, press
the gearshift lever to the right. Otherwise,
the engine could be damaged if you inadvert-
ently shift into 3rd or 4th gear.<
Reverse gear
Select this only when the vehicle is stationary.
When the gearshift lever is pressed to the left, a
slight resistance has to be overcome.
Automatic transmission with
Steptronic*
In addition to fully automatic operation, you can
also manually shift with the Steptronic, refer to
page57.
Vehicle parking
To prevent the vehicle from rolling,
always select position P and apply the
parking brake before leaving the vehicle with
the engine running.<
Disengaging the remote control
In order to remove the remote control from the
ignition lock, you must first move the selector
lever to position P and switch off the engine:
interlock. Removing the remote control from
the ignition lock, refer to page54.

maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is a technological advance
over the familiar cruise control and is a welcome
relief from the constant adjustment of speed
that can accompany driving in traffic on high-
ways or other high-speed thoroughfares. Espe-
cially on longer trips, the system can reduce
fatigue and tension, while increasing your
enjoyment of driving. Please use it safely and
responsibly.
Within the limits of its capability, the system
automatically adapts the car's speed to that of a
slower vehicle in front of you. You can specify
the distance to be maintained from the vehicle
in front in four stages. For safety reasons, the
distance is speed-dependent. Based on your
selected distance setting, the system automat-
ically decreases the throttle setting and lightly
applies the brakes if necessary. The vehicle
brake lamps will automatically illuminate to sig-
nal a following driver to take action. In addition,
it may be necessary for the vehicle or the driver
to downshift, depending on the kind of trans-
mission your vehicle is equipped with, to main-
tain the distance setting selected. If the vehicle
ahead speeds up or when the lane ahead
becomes clear, your vehicle will accelerate to
the speed you have selected by increasing the
throttle setting and shifting gears automatically
or by the driver as needed. Your selected speed
will be held when driving downhill, too.
Since this active cruise control system is a new
technology and operates differently from con-
ventional cruise control systems which you may
be accustomed to, you are strongly urged to
read all of the pages relating to this system
before use. Pay special attention to the System
limitations section beginning on page66.
Braking sensation
>If you step on the brake pedal while the sys-
tem is braking, pedal sensation will be
slightly different from the usual.
>Possible noises during automatic braking
are normal.
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you
drive at very low engine speeds for an extended
period.
Range of applications
The minimum desired speed is 20 mph or
30 km/h, the maximum desired speed is
110 mph or 180 km/h.
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver’s own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow,
strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you. Otherwise, driving situations could
result that pose the risk of accidents.<
