WARNING
•City Safety™ only reacts to vehicles traveling in the same direction as yourvehicle and does not react to smallvehicles or motorcycles or to people oranimals.
• City Safety™ is not activated whenyour vehicle is backing up.
• City Safety™ functions at speeds upto 30 mph (50 km/h). This system canhelp prevent a collision if the
differ-
ence in speed between your vehicle
and the vehicle ahead is less than9 mph (15 km/h). If the difference inspeed is greater, a collision cannot beavoided but the speed at which thecollision occurs can be reduced. Thedriver must apply the vehicle’s brakesfor full braking effect.
• City Safety™ will not intervene in apotential collision situation if the vehi-cle is being driven actively. The driveris always responsible for maintaining asafe distance to a vehicle or objectahead.
Function
Location of the laser sensor in the windshield 2
City Safety™ monitors traffic ahead of you using a laser sensor mounted in the uppersection of the windshield. If a collision isimminent, City Safety™ will automaticallyapply the brakes, which may feel like hardbraking. If the difference in speed between your vehi- cle and the vehicle ahead is more thanapproximately 9 mph (15 km/h), City Safety™alone cannot prevent a collision from takingplace. The driver must apply the brakes tohelp avoid a collision or reduce its effect. When the function activates and applies the brakes, a message will appear in the informa- tion display to indicate that the system is/hasbeen active.
NOTE
•
When City Safety™ applies the brakes, the brake lights will illuminate.
• In cases where City Safety™ has stop-ped the vehicle, the system will thenrelease the brakes. The driver mustapply the brakes to keep the vehicle ata standstill.
Using City Safety™
NOTE
The City Safety™ function is activated automatically each time the engine hasbeen switched off and restarted.
On and OffIn certain situations, it may be desirable to switch City Safety™ off, such as when drivingin close quarters where leaves, branches, etc.may obscure the hood and windshield. When the engine is running, City Safety™ can be switched off as follows:

If the engine is switched off, City Safety™ will reactivate when the engine is restarted.
WARNING
The laser sensor emits light when the igni- tion is in mode II or higher, even if City
Safety™ has been switched off.
To switch City Safety™ on again:
• Follow the same procedure as for switch- ing City Safety™ off but select
On.
Limitations
The sensor used by City Safety™ is designed to detect cars and other larger motor vehiclesahead of your vehicle in both daylight anddarkness.
WARNING
The laser sensor has certain limitations and its function may be reduced (or it maynot function at all) in conditions such asheavy rain or snowfall, or by dense fog orthick, blowing dust or snow. Condensa-tion, dirt, ice or snow on the windshieldmay also interfere with the sensor’s func-tion.
Objects such as warning flags hanging from long objects on the roof or accessories suchas auxiliary lights or protective arches on thefront of the vehicle that are higher than thehood may also impede the sensor’s function. Braking distance to the vehicle ahead increa- ses on slippery road surfaces, which mayreduce City Safety’s capacity to avoid a colli-sion. In situations like this, the DSTC system(see page 152) will help provide the best pos-sible braking capacity and stability. City Safety™ emits a laser beam and meas- ures the way in which the light is reflected.Therefore, vehicles or objects with low-reflec-tive surfaces may not be detected. Normally,the license plate and taillight reflectors givethe rear section of a vehicle ahead sufficientreflective surfaces to be detected.
NOTE
•Keep the windshield in front of the laser sensor free of ice, snow, dirt, etc.See page 174.
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sen-sor. Keep the hood free of ice andsnow.
• Do not mount or in any way attachanything on the windshield that couldobstruct the laser sensor.
Troubleshooting
If Windscreen Sensors blocked appears in
the information display, this indicates that the City Safety™ laser sensor is obstructed insome way and cannot detect vehicles aheadof you, which means that the system is notfunctioning. However, this message will not be displayed in all situations in which the sensor isobstructed. For this reason, the driver mustensure that the area of the windshield in frontof the sensor is always kept clean. The following table shows some of the situa- tions that can cause the message to be dis-played and suggested actions.

Warning
Warning distance.
The warning distance determines the level of sensitivity used by the system. The warning distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to Normal.
WARNING
• The setting Short should only be used
in situations where traffic is light and moving at low speeds.
• Pedestrian and Cyclist Detection withFull Auto Brake alerts the driver to therisk of a collision but this function can-not reduce the driver’s reaction time.
• For the system to be as effective aspossible, it is recommended that Dis-tance Alert be set to 4 or 5, seepage 170.
NOTE
•When Adaptive Cruise Control is used, the warning light and signal will beused by that function, even if thewarnings provided by Pedestrian andCyclist Detection with Full Auto Brakehave been deactivated by the driver.
• In situations where traffic is moving atconsiderably different speeds, or if thevehicle ahead brakes suddenly, warn-ings may be considered to be late, even if the setting
Long has been
selected.

information on the radar sensor and its limita- tions, see page 166.
NOTE
If warnings are given too frequently, the warning distance can be reduced (seepage 181). This causes the system to pro-vide later warnings, which decreases thetotal number of warnings provided.
WARNING
•
The system is not activated at speeds under approx. 2 mph (4 km/h). There-fore, it will not brake your vehicle if youapproach a vehicle ahead at very lowspeed, such as when parking.
• The driver's actions always have high-est priority and override the Pedestrianand Cyclist Detection with Full AutoBrake system. This means that thesystem will not intervene in situationswhere the driver is actively steering,braking or pressing the acceleratorpedal, even if a collision is imminent.
• When Auto-brake has prevented a col-lision with a stationary object, yourvehicle will remain at a standstill forapprox. 1.5 seconds. If your vehiclehas been braked for a moving vehicleahead, your vehicle's speed will bereduced to the same speed as thatvehicle's.
The camera’s limitationsThe camera is used by Pedestrian and Cyclist Detection with Full Auto Brake, Driver AlertControl (see page 189), and Lane DepartureWarning (see page 191).
NOTE
•To help protect the camera in very hot conditions, it may be temporarilyswitched off for approximately 15minutes after the engine has beenstarted.
• Keep the section of the windshield infront of the camera clean and free ofice, snow, or condensation.

* Option/accessory, for more information, see Introduction.189
Introduction
The Driver Alert System is designed to help a driver who may be becoming fatigued or whois inadvertently leaving the lane and consistsof two different functions that can beswitched on together or separately.
• Driver Alert Control (DAC)
• Lane Departure Warning (LDW) 1
, see
page 191
• Lane Keeping Aid (LKA) 2
, see page 194
When one or both of the functions has beenswitched on, it is in standby mode and is acti-vated when the vehicle exceeds a speed of40 mph (65 km/h). The function deactivates if the vehicle's speed goes under 37 mph (60 km/h). Both functions use a camera that is depend- ent on the road/lane being clearly marked bypainted lines on each side.
WARNING
The Driver Alert System does not function in all situations and is designed to be asupplementary aid. It is not, however,intended to replace the driver’s attentionand judgement.
Driver Alert Control (DAC)
This function is intended to alert the driver if his/her driving becomes erratic, such as if thedriver is distracted or fatigued.
NOTE
The camera has certain limitations, see page 166.
A camera monitors the painted lines marking the lane in which the vehicle is traveling andcompares the direction of the road with thedriver’s movements of the steering wheel.The driver is alerted if the vehicle does notfollow the lane smoothly. DAC is designed to help detect a slowlychanging driving pattern. It is primarilyintended to be used on main roads and is notmeant for use in city traffic.
WARNING
•
DAC is not intended to extend the duration of driving. Always plan breaksat regular intervals to help remain alert.
• In certain cases, fatigue may not affectthe driver’s behavior. In situations ofthis type, no warning will be provided.Therefore, it is important to takebreaks at regular intervals, regardlessof whether or not DAC has given awarning.
LimitationsIn certain situations, DAC may provide warn- ings even if the driver’s driving pattern hasnot become erratic.
• if the driver is testing the LDW function, see page 191
• if the driver is testing the LKA function,see page 194
• in strong crosswinds
• on grooved road surfaces.

Lane Departure Warning (LDW) 1
Your vehicle may be equipped with Lane Departure Warning (LDW) or Lane KeepingAid (LKA), depending on your choice of engine.
If you are uncertain as to which of
these optional systems is in your vehicle:
• Press the
MY CAR button on the center
console to open the menu system. Scroll to
SettingsDriver support system.
The system in your vehicle (Lane
Departure Warning or Lane Keeping
Aid) will be displayed there.
If your vehicle is equipped with Lane Keeping Aid (LKA), see page 194 for detailed informa-tion.The illustration is generic
LDW is designed to help reduce the risk of accidents in situations where the vehicle unintentionally leaves its lane and there is arisk of driving off the road or into the oppositelane. It uses the camera located at the center,upper edge of the windshield to monitor theroad's/lane’s side marker lines. If the vehiclecrosses a side marker line or the road’s cen-ter dividing line, the driver will be alerted byan audible signal.
