Manually unlocking and locking the
transmission lock
In the event of a power supply interruption, e.g.
when the battery is dead or disconnected or
when there is an electrical malfunction, the
transmission lock must be released manually;
otherwise, the rear wheels are locked and the
vehicle cannot be towed.
Step on the brake when manually unlock-
ing the transmission lock; otherwise,
there is a danger of the vehicle rolling.<
The transmission lock should only be released
for towing. Reengage the transmission lock
after parking the vehicle at its destination.
If it also becomes necessary to manually
release the parking brake, follow this sequence:
1.Start by manually releasing the parking
brake, refer to page60.

Programmable cruise control
The concept
The programmable cruise control is available
for use at speeds of approx. 20 mph/30 km/h
and higher. The vehicle maintains and stores
the speed that you set using the lever mounted
on the steering column.
You can also use the multilevel preset mode to
store six desired speeds for later selection with
the lever, refer to page67.
This feature assists you in quickly adapting the
vehicle speed to specific road conditions, e.g.
changes in speeds limits.
Do not use the programmable cruise con-
trol when unfavorable conditions do not
permit you to drive at a constant speed, e.g.
when driving on winding roads, in heavy traffic
or under poor road conditions such as snow,
rain, ice, or a loose road surface. If you do, you
could lose control of the vehicle and cause an
accident.<

4Resuming stored speed
Maintaining speed, storing, and

Press lever to resistance point, arrow 1:
The system maintains and stores the current
vehicle speed. The pointer5 in the speedome-
ter indicates this speed, refer to Displays in
speedometer on page68. Each time the lever is
pressed again briefly, the speed is increased by
approx. 1 mph or 1 km/h.
Push the lever to the resistance point for a
longer time:
The vehicle accelerates without pressure on
the accelerator pedal. The system maintains
and stores your current speed as soon as you
release the lever.
Press the lever past the resistance point if no
desired speeds6 are stored:
The pointer5 jumps to the next multiple of
5 mph or 10 km/h and then further, as long as
the lever is held. The speed then indicated is
reached and stored.
The vehicle may accelerate beyond the preset
speed on steep downhill stretches where the
engine's braking action alone may not be suffi-
cient to slow the vehicle. Speed can drop on
uphill grades if the engine output is insufficient.

Active cruise control*
The concept
With active cruise control you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control represents 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
highways or other high-speed thoroughfares.
Especially on longer trips, the system can
reduce fatigue and tension, while increasing
your enjoyment of driving. Please use it safely
and responsibly.
In addition to maintaining a steady cruising
speed, if you encounter slower vehicles ahead,
active cruise control will, within the scope of
given possibilities, adjust your vehicle's speed
automatically, permitting you to flow with the
traffic without having to frequently intervene.
If, for example, while cruising at the selected
speed, you begin to approach a slower vehicle
ahead of you in the same lane, the system will
reduce your vehicle's speed to the same as that
of the vehicle ahead to maintain your selected
following distance between your vehicle and
the vehicle ahead. You can vary the distance,
which is additionally speed-dependent. Based
on your selected distance setting, the system
automatically decreases the throttle setting and
lightly applies the brakes if necessary. The vehi-
cle brake lamps will automatically illuminate to
signal a following driver to take action. In addi-
tion, it may be necessary for the vehicle to
downshift to maintain the distance setting
selected. If the vehicle ahead speeds up or when the lane ahead becomes clear, your vehi-
cle will accelerate to the speed you have
selected by increasing the throttle setting and
shifting gears as needed. This setting is also
maintained on steep stretches, but the vehicle
speed can fall below this on uphill grades if the
engine output is insufficient to maintain speed.
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
Since this active cruise control system is
a new technology and operates differ-
ently from conventional cruise control systems
to which you may be accustomed, you are
strongly urged to read all of the pages relating
to this system before use. Pay special attention
to the information contained in the Things to
know about active cruise control section begin-
ning on page72.<
Brake pedal feel
>When the system brakes and you also
depress the brake pedal, a somewhat differ-
ent braking feeling results.
>Any noises produced during automatic
braking are normal.
Applications
As with conventional cruise control systems,
active cruise control in no way diminishes or
substitutes for the driver's own personal
responsibility, alertness, and awareness in
adjusting speed, braking, or otherwise control-
ling 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 interchanges, service/
parking areas or toll booths. It is also important
to regulate your vehicle's speed and distance
setting within applicable legal limits. Adapt the

Driving
70 desired speed to traffic conditions, control both
your driving speed and safe following distance,
and remain ready to brake at all times. 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. Oth-
erwise driving situations can arise that consti-
tute an accident hazard.
The minimum desired speed is 20 mph or
30 km/h, the maximum is 110 mph or 180 km/h.

Deactivating cruise control
Press the lever up or down. The displays in the
speedometer go out.
In addition, the system is automatically deacti-
vated:
>when the speed is reduced to below 20 mph
or 30 km/h due to a traffic situation
>when DTC is activated or DSC is deacti-
vated
>when the system does not recognize any
objects for an extended period of time, e.g. on infrequently traveled roads without a
shoulder or guard rails, or if the radar sensor
is covered with dirt, refer to page72
>when you actuate the parking brake during
driving
>when you shift the transmission into posi-
tion N
If the system is deactivated, then it is nec-
essary for the driver to actively intervene
by braking and possibly swerving. Otherwise,
there is the danger of an accident.<
Background lighting
You can switch off the backlighting of the
speedometer and tachometer when the system
is deactivated if no other functions are being
displayed, e.g. the advance warning field in the

Warning lamps
The display flashes and a chime
sounds.
The system asks you to intervene
by braking or with an evasive
maneuver. The active cruise control cannot
automatically restore the distance to the vehicle
driving ahead.
The display does not relieve you of the respon-
sibility for adapting desired speed and driving
style to traffic conditions.
Automatic intervention by ABS or
DSC. The active cruise control
intervenes by braking until you
actively intervene.
Radar sensor
Heavy rain and also dirt, snow, or ice can limit
the detection of vehicles ahead. If needed,
clean the radar sensor under the front bumper.
When doing so, be particularly careful in remov-
ing layers of snow and ice.
If the sensor is not aligned properly, the active
cruise control cannot be activated.
Things to know about active cruise control
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,

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.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
