Cruise control*
The concept Cruise control is available for use at speeds of approx. 20 mph or 30 km/h. The car then stores and maintains the speed that you specify using the lever on the steering column. In order to maintain the specified speed, the system brakes the vehicle when the engine braking effect is insufficient on downhill gradients.
Do not use cruise control when driving at constant speed is prevented by adverse conditions, e.g. winding roads, dense traffic or poor road conditions due to, e.g., snow, rain, ice or loose surfaces. Otherwise, you could lose control of the vehicle and cause an accident as a result.<
1 Intermittent operation. When reverse gear is engaged, the system switches to contin- uous operation.
2 Cleaning the rear window The rear window wiper does not move if the lever is in position 1 before the ignition is switched on. To switch on the rear window wiper: 1. Move the lever to its home position. 2. Reselect the desired position.
Do not use the washers when the washer fluid reservoir is empty; otherwise, you
will damage the washer pump.<
Washer fluid
Washer fluid antifreeze is flammable. Therefore, keep it away from ignition
sources and only store it in the closed original container that is kept out of reach of children; otherwise, there is a risk of personal injury. Comply with the instructions on the con- tainer.<
Washer fluid filler neck
Only refill washer fluid when the engine is cool to avoid contact with hot engine parts. Otherwise, fluid spills constitute a fire hazard and a risk to personal safety.<
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.

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 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 page 69.
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.<

68
System limitations
Always remember that the range and abil- ity of the system does have physical limi- tations. It will not apply the brakes or decelerate your vehicle when there is a slow-moving vehi- cle, stopped vehicle or stationary object ahead of you, as for example, at a traffic light or a parked vehicle. Also, the system does not react to oncoming traffic, pedestrians or other types of potential traffic such as a rider on horseback. It is also possible that the system may not detect smaller moving objects such as motor- cycles or bicycles. Be especially alert when encountering any of these situations as the sys- tem will neither automatically 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.<
Active cruise control is not and must not be used as a collision avoidance/warning
system.< If while your vehicle is actively following a vehi- cle 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, unobstructed 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 manner 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.
While active cruise control is capable of braking your vehicle automatically when
you approach a slower vehicle ahead, it is important to be aware that the ability of the system to apply the brakes is also limited, e.g. when you reduce your desired speed sharply. The system cannot stop your vehicle. It uses only a portion of braking system capacity and does not utilize the full capacity of the vehicle braking system. Therefore, the system cannot decrease your speed for large differences in speed between your vehicle and the vehicle ahead. Examples: when you approach a vehicle traveling at a much lower speed than your own speed such as approaching a toll booth or when a much slower vehicle cuts in front of you at close range.< Active cruise control can only decelerate the vehicle to approx. 20 mph or 30 km/h.
69
Swerving vehicles
When a vehicle moves from an adjacent lane into your lane, active cruise control will not rec- ognize this vehicle until it is fully in your lane ahead of your vehicle.
When a vehicle ahead suddenly swerves into your lane, the system may not be able to maintain the selected distance automatically. This also applies to great differences in speed between you and vehicles ahead, e.g. when quickly approaching a truck. There is a risk of collision. Once the system has established that a vehicle is indeed in front of you, it will indicate that you must brake and/or maneuver the vehi- cle yourself. Take action yourself; otherwise, there is a risk of an accident.<
Behavior in curves
In approaching a curve, it is possible that active cruise control would react briefly to a vehicle in the adjacent lane. In addition, the system can sense if your vehicle is in a curve and may not accelerate. If your vehicle decelerates in either case, you can choose to overcome the deceler- ation by briefly pressing the accelerator pedal.
Your responsibility Your actions have priority at all times. When you press the accelerator pedal while driving with active cruise control, the automatic braking function will be temporarily interrupted. Once you release the accelerator pedal, the desired speed or the selected distance to the vehicle ahead is achieved again.
Do not leave your foot on the accelerator pedal and make sure that no objects such as floor mats are lying on the accelerator pedal. Otherwise, the system may not be able to brake the vehicle.<
Because of the limited range of the system, it is possible that in curves or on the peaks and val- leys of hilly roads, a vehicle ahead may be rec- ognized late, or not at all. Therefore, it is up to the driver to select a speed that is prudent in view of the curves and terrain of the roadway.
