The rain sensor is automatically deac-
tivated when you switch off the igni-
tion.<
Deactivate the rain sensor when
passing through an automatic car
wash. Failure to do so could result in dam-
age caused by undesired wiper activa-
tion.<
Selecting wiper fold-out position
Important for changing wiper blades, when
folding away from windshield to prevent
blades from sticking when ice forms, etc.
1.Switch off the engine and remove the
remote control from the ignition lock
2.Press the wiper lever up and maintain
pressure for about 3 seconds until the
wipers are roughly vertical: this is the
fold-out position.
After folding the wipers back against the
windshield you will need to reactivate the
wiper system:
1.Insert the remote control to activate the
radio mode in the ignition lock
2.Apply brief upward pressure to the
wiper lever. The wipers return to their
retracted position and are ready for nor-
mal operation.
To prevent damage to the wipers,
always fold them back against the
windshield before switching on either the
radio mode or the ignition.<
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks
and open flames, and store it in tightly
closed containers well out of the reach of
children. Always observe the instructions
for use provided on the containers.<
We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Windshield and headlamp washer
system
Capacity: 6.3USquarts/6liters.
Fill with water and – if required – with a
washer antifreeze, according to manufac-
turer's recommendations.
Programmable cruise
control
The concept
The programmable cruise control is avail-
able 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 6 desired speeds for later
selection with the same lever, refer to
page74.
This feature assists you in quickly adapting
the vehicle speed to specific road condi-
tions, e.g. changes in speeds limits.
Do not use the programmable cruise
control when driving on winding
roads, in heavy traffic or in poor road con-
ditions, e.g. snow, rain, ice, loose road sur-
face, that do not permit a constant speed.<

One lever for all functions
1 Maintaining and storing speed,
accelerating
Press the lever up to the resistance point:
The system maintains and stores the cur-
rent vehicle speed. Every time you briefly
press the lever, the vehicle's speed
increases by roughly 1 mph/1 km/h.
Press the lever longer:
The vehicle accelerates without pressure
on the accelerator pedal. The system main-
tains and stores your current speed as
soon as you release the lever.
The vehicle may accelerate beyond
the preset speed on steep downhill
stretches where the engine's braking effect
alone may not be sufficient to slow the
vehicle. Speed can drop on uphill grades if
the engine output is insufficient.<
2 Maintaining and storing speed,
decelerating
Pull lever:
Functions similar to1, only the vehicle
speed is decreased.
3 Interrupting cruise control
With the cruise control active, briefly press
the lever up or down.
In addition, cruise control is interrupted
automatically

Active cruise control*
The concept
With active cruise control you can select a
desired speed which is not only automati-
cally maintained when driving on open
roadways, but also varied to maintain a
selected distance setting 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 freeways 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 responsi-
bly.
In addition to holding a steady cruising
speed, if you do encounter slower vehicles
ahead, active cruise control will, within the
scope of given possibilities, adjust your
vehicle’s speed automatically so that you
can flow with the traffic without frequent
intervention by the driver. 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 distance setting between your
vehicle and the vehicle ahead. There are
four settings for distance, which is addi-
tionally speed-dependent. Based on your
selected distance setting, the system auto-
matically decreases the throttle setting and
lightly applies the brakes if necessary.

Driving
76 The vehicle brake lamps will automatically
illuminate to signal a following driver to take
action. In addition, it may be necessary for
the vehicle to downshift to maintain the dis-
tance 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 increas-
ing the throttle setting and shifting gears as
needed.
Active cruise control is not and must
not be used as a collision avoidance/
warning system.<
Since this active cruise control sys-
tem is a new technology and operates
differently from conventional cruise control
systems 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 in this manual
beginning on page78.<

road conditions, traffic, applicable laws and
driving recommendations for safe following
distance.<
Things to know about active cruise control
As with conventional cruise control
systems, active cruise control in no
way diminishes or substitutes for the
driver's own personal responsibility, alert-
ness and awareness in adjusting speed,
braking or otherwise controlling the vehi-cle. The driver should decide when to use
the system on the basis of road, traffic, vis-
ibility, and weather conditions. Active
cruise control is intended for use on high-
way-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, slip-
pery 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. 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
ability of the system does have physi-
cal limitations. It will not apply the brakes or
decelerate your vehicle when there is a
slow-moving vehicle, stopped vehicle or
stationary object ahead of you, as for
example, at a traffic light or a parked vehi-
cle. Also, the system does not react to
oncoming traffic, pedestrians or other type
of potential traffic such as a rider on horse-
back. It is also possible that the system
may not detect smaller moving objects
such as motorcycles or bicycles. Be espe-
cially alert when encountering any of these
situations as the system will neither auto-
matically brake, nor provide a warning to
you. Also, be aware that every decrease in
the distance setting allows your vehicle to
come closer to a vehicle in front of you and
requires a heightened amount of alert-
ness.<
If while your vehicle is actively following a
vehicle in front of you and the vehicle
ahead speeds up or the lane ahead
becomes clear, then your vehicle will
accelerate to the speed you have selected.
Be aware that changing to a clear, unob-
st r uc ted lan e w il l als o r esu lt in y ou r v eh icle
accelerating.
Be certain to deactivate the system
when you pull into an exit lane for a
highway off-ramp.<
Also, vehicles traveling in a staggered man-
ner on a highway may cause a delay in the
system's reaction to a vehicle in front of you
or may cause the system to react to a vehi-
cle actually in the lane next to you. Always be ready to take action or apply the brakes
if necessary.
Active cruise control can only decelerate
the vehicle to approx. 20 mph/30 km/h. If
the system reduces vehicle speed below
20 mph/30 km/h or if DSC/ABS is engaged
while driving, the system will automatically
deactivate.
Remember, the system cannot stop
your vehicle. In addition, the system is
deactivated whenever the driver applies
the vehicle brakes, shifts the transmission
from drive/D to neutral/N, or deactivates
DSC. After any deactivation, the system will
no longer automatically activate the vehicle
brakes, which means the driver must inter-
vene and resume manual braking. You
should then reactivate the system only
when you are fully aware of the prior speed
and distance settings.<
Active cruise control may brake when you
reduce the stored desired speed; however,
the driver must constantly monitor traffic
and intervene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off,
too, and any settings you have selected are
canceled.
Behavior in curves
Because of the limited range of the system,
it is possible that in curves or on the peaks
and valleys of hilly roads, a vehicle ahead
may be recognized late, or not at all. There-
fore, it is up to the driver to select a speed
that is prudent in view of the curves and
terrain of the roadway.
