Collision warning* – function
Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work together to detect a pedestrian, a cyclist, sta-tionary vehicles and vehicles that are movingin the same direction as your vehicle. If thereis a risk of collision with a vehicle, a cyclist ora pedestrian, the driver is alerted by a flash-ing red warning light and an audible warningsignal. The system is active at speeds above3 mph (4 km/h).
Brake SupportIf the risk of collision continues to increaseafter the collision warning has been given,Brake Support is activated. Brake Supportprepares the brake system to react quickly,and the brakes are applied slightly. This maybe experienced as a light tug. If the brakes are applied quickly, full braking effect will be provided. Brake Support alsoincreases brake force if the system deter-mines that the driver has not applied ade-quate pressure on the brake pedal.
Auto-brakeIf a collision is imminent and the driver hasnot applied the brakes or begun to steeraround the vehicle, pedestrian or a cyclist,the auto-brake function is activated withoutthe driver pressing the brake pedal. Full brakeforce is applied to help reduce the vehicle’sspeed when the collision occurs or limitedbrake force is applied if this is sufficient toavoid the collision.
NOTE
The auto-brake and brake support func- tions are always on and cannot be turnedoff.

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, see Dis-tance Alert – operation (p. 193).
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.

• For optimal cyclist detection, CitySafety™ must be activated.
WARNING
Pedestrian and Cyclist Detection with Full Auto Brake is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is alwaysresponsible for operating the vehicle in asafe manner. The system cannot detect a bike/cyclist if: •He/she is wearing loose-fitting clothing that may obscure body contours
• The bike is approaching your vehiclefrom the side
• The bike is not equipped with a rear-facing red reflector
• The bike is carrying large objects
• Most of the cyclist's body or the bikeitself cannot be "seen" by the system'scamera

Collision warning* – Pedestrian detection
The system cannot identify all pedestrians
The Pedestrian and Cyclist Detection with Full Auto Brake system can only identify anddetect a pedestrian who is standing upright.This person can be standing still, walking orrunning. This means that the system has to be able to identify a person's head, arms, shoulders,legs, the upper and lower parts of the bodyand a person's pattern of movement whenwalking or running. If parts of the body are not visible to the cam- era, the system cannot detect the pedestrian. The following conditions apply:
• In order to detect a pedestrian, the sys- tem must have a full view of the person's

entire body and the person must be at least 32 in. (80 cm) tall.
• The system cannot detect a pedestriancarrying a large object.
• The camera's capacity to see a pedes-trian at dawn or dusk is limited, much asit is for the human eye.
• The camera's function is deactivated andwill not detect a pedestrian in darkness orin tunnels, even if there is street lighting inthe area.
WARNING
•Pedestrian and Cyclist Detection with Full Auto Brake is designed to be asupplementary driving aid. It is not,however, intended to replace the driv-er's attention and judgement. Thedriver is always responsible for operat-ing the vehicle in a safe manner.
• The system cannot detect all pedes-trians in all situations, such as in dark-ness/at night and cannot detect parti-ally hidden pedestrians, people whoare less than approx. 32 in. (80 cm)tall, or people wearing clothing thatobscures the contours of their bodies.

Collision warning* – limitations
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead may makethe visual warning signal in the windshield dif-ficult to see. For this reason, always activatethe audible warning signal. Slippery driving conditions increase braking distance, which can reduce the system'scapacity to avoid a collision. In these condi-tions, the ABS and stability systems providethe best possible braking effect while helpingto maintain stability.
NOTE
The visual warning signal may be tempo- rarily disengaged in the event of high pas-senger compartment temperature due tostrong sunlight, etc. If this occurs, theaudible warning signal will be used, even ifit has been deactivated in the menu sys-tem.

The camera’s limitations
The camera has the same limitations as the human eye. The camera is used by Pedestrian and Cyclist Detection with Full Auto Brake Collision warn-ing – introduction (p. 204), Active High Beams(Active high beams (AHB)* (p. 88)), Road SignInformation (Road Sign Information (RSI)* –introduction (p. 174)) and Driver Alert System(Driver Alert System (p. 217)) with LaneDeparture Warning or Lane Keeping Aid.
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.
WARNING
•
The camera has the same type of limi- tations as the human eye, i.e., it can-not see as well in heavy snowfall orrain, thick fog or in heavy blowing dustor snow. In such conditions, systemsdepending on the camera may experi-ence greatly reduced functionality ormay be temporarily deactivated.
• Never place any objects, decals, etc.,on the windshield in front of the cam-era. This could reduce or block thecamera’s function, and could causeone or more of the systems that utilizethe camera to stop functioning.
• Strong sunlight, reflections from theroad surface, ice or snow covering theroad, a dirty road surface, or unclearlane marker lines may drasticallyreduce the camera’s capacity todetect the side of a lane, a pedestrian,a cyclist or another vehicle.

WARNING
•Always remove the remote key from the ignition slot when leaving the vehi-cle and ensure that the ignition inmode
0 (see Ignition modes (p. 77) for
information about the ignition modes).
• On vehicles with the optional keylessdrive, never remove the remote keyfrom the vehicle while it is being drivenor towed.
• Always place the gear selector in Parkand apply the parking brake beforeleaving the vehicle. Never leave thevehicle unattended with the enginerunning.
• Always open garage doors fully beforestarting the engine inside a garage toensure adequate ventilation. Theexhaust gases contain carbon monox-ide, which is invisible and odorless butvery poisonous.
NOTE
•
After a cold start, idle speed may be noticeably higher than normal for ashort period. This is done to help bringcomponents in the emission controlsystem to their normal operating tem-perature as quickly as possible, whichenables them to control emissions andhelp reduce the vehicle's impact on the environment 3
.
CAUTION
• When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never acceler-ate until after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harshengagement and premature transmis-sion wear.
• Selecting
P or N when idling at a
standstill for prolonged periods of timewill help prevent overheating of theautomatic transmission fluid.
