Indicator and warning lamps 
Technology that monitors itself 
The indicator and warning lamps identified 
by the 
+ symbol are subjected to an oper-
ation check each time you switch on the 
ignition or start the engine. They each light 
up once for different periods of time. 
When a malfunction occurs in a monitored 
system, the corresponding lamp will either 
fail to go out when the engine is started, or 
it will come on again during normal driving. 
For information on how you should respond 
when this happens, please refer to the 
pages indicated.

Deactivating the rain sensor 
Briefly press the button again. The indica-
tor lamp goes out. 
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: fold-out 
position. 
After folding the wipers back against the 
windshield you will need to reactivate the 
wiper system: 
1.Switch on the radio mode
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

Capacity: 6.3 US quarts/6 liters. 
Fill with water and Ð if required Ð 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 
page 73. 
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 as far as 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 back to resistance point: 
The system maintains and stores the cur-
rent vehicle speed. Every time you briefly 
press the lever the vehicle's speed 
decreases by roughly 1 mph/1 km/h. 
Pull the lever longer:
The throttle aperture is automatically 
reduced, slowing the vehicle. The system 
maintains and stores your current speed as 
soon as you release the lever. 
3 Interrupting cruise control 
With the cruise control active, briefly press 
the lever up or down. In addition, cruise control is interrupted 
automatically 
>when you apply pressure to the brake 
pedal 
>when you select neutral position of the 
automatic transmission
>when the DSC Dynamic Stability Con-
trol is in active operation. 
4 Recalling stored speed 
Briefly press button 4: the vehicle acceler-
ates to and maintains the last speed stored.

If 6 speeds have already been stored, 
it will be necessary to delete one 
before entering a new preset speed.<
While driving 
Activate multilevel preset mode. 
Press button 4 for approx. 3 seconds. The 
respective driven speed is applied as the 
desired speed and displayed with 6. 
If all of the graduations flash at once, 
this indicates that 6 desired speeds 
have already been stored. You must then 
delete at least one.<
Deleting desired speeds 
Select the desired speed 5. 
Press button 4 for approx. 3 seconds. 
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 respon-
sibly.  

Driving
74 In addition to holding a steady cruising 
speed, if you do encounter slower vehicles 
ahead, active cruise control will Ð within the 
scope of given possibilities Ð adjust your 
vehicle's speed automatically so that one 
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. 
The vehicle brake lamps will automatically 
illuminate to signal a following driver to 
take action. In addition, it may be neces-
sary 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 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 to, 
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 page 77.<

Adjust your desired speed to the traf-
fic conditions and remain ready to 
brake at all times. Great differences in 
speed to the vehicles driving ahead, e.g. 
when quickly approaching a truck or when 
another vehicle swerves into your lane, 
cannot be compensated for by the sys-
tem.< 
Activating the system 
From approx. 20 mph/30 km/h you can 
activate the system by pressing the lever forward or pulling it back: 
The current driving speed is stored as a 
desired speed and briefly displayed in the 
speedometer, refer to arrow. 
If the display ACC --- mph/km/h 
appears briefly in the speedometer, 
it might be that conditions necessary for 
operation are not currently being met. 
To call up Check Control messages, refer 
to page 83.< 
1 Storing and increasing desired 
speed 
Press the lever forward: 
The system applies and stores your current 
speed as a desired speed. The speedome-
ter indicates this speed. 
Subsequently pressing forward increases 
the desired speed to the next 5-mile place/ 
10 km/h. 
Each time the lever is pressed forward 
again, the desired speed is increased by 
another 5  mph/10  km/h until a maximum of 
110 mph/180 km/h is reached. The speed 
then displayed is stored and reached on a 
clear road. 
2 Storing and decreasing desired 
speed 
Pull back the lever: 
The current driving speed is rounded off to 
the next 5-mile place/10 km/h, displayed 
and stored. 
Each time the lever is pulled back again, 
the desired speed is decreased by another 
5  mph/10  km/h until the minimum speed of 
20 mph/30 km/h is reached. The speed 
then displayed is stored and reached on a 
clear road. 
3 Deactivating the system 
Press the lever up or down while the sys-
tem is active. The displays in the speedom-
eter disappear. You can use the system 
again as required. 
In addition, the system is deactivated auto-
matically:

Things to know about active cruise control 
As with conventional cruise control 
systems, active cruise control in no 
way diminishes or substitutes for the 
driverÕs 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, 
visibility, 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 phys-
ical 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-
structed lane will also result in your vehicle 
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 
vehicle 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
