2018 FORD FOCUS Owners Manual

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction controllight illuminates steadily if thesystem detects a failure. Make sureyou did not manually disable the tractioncontrol system using the informationdisplay controls or the switch. If thestability control and traction control lightis still illuminating steadily, have thesystem serviced by an authorized dealerimmediately. Operating your vehicle withthe traction control disabled could lead toan increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
The system automatically turns on eachtime you switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involvingbraking system, aftermarket roofracks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronic stabilitycontrol system. In addition, installing anystereo loudspeakers may interfere withand adversely affect the electronic stabilitycontrol system. Install any aftermarketstereo loudspeaker as far as possible fromthe front center console, the tunnel, andthe front seats in order to minimize the riskof interfering with the electronic stabilitycontrol sensors. Reducing theeffectiveness of the electronic stabilitycontrol system could lead to an increasedrisk of loss of vehicle control, vehiclerollover, personal injury and death.
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicleincreasing the risk of personal injury orproperty damage. Activation of theelectronic stability control system is anindication that at least some of the tireshave exceeded their ability to grip the road;this could reduce the operator’s ability tocontrol the vehicle potentially resulting ina loss of vehicle control, vehicle rollover,personal injury and death. If your electronicstability control system activates, SLOWDOWN.
The system automatically turns on eachtime you switch the ignition on.
If a fault occurs in either the stabilitycontrol or the traction control system, youmay experience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and tractioncontrol systems do not enhance yourvehicle's ability to maintain traction ofthe wheels.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake, the brakepedal may move as the system applieshigher brake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides byapplying brakes to one or more of thewheels individually and, if necessary,reducing engine power.
Traction Control
The system enhances your vehicle’s abilityto maintain traction of the wheels bydetecting and controlling wheel spin. SeeUsing Traction Control (page 150).

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, pleaseread and understand the limitationsof the system as contained in thissection. Sensing is only an aid for some(generally large and fixed) objects whenmoving on a flat surface at parking speeds.Certain objects with surfaces that absorbultrasonic waves, surrounding vehicle'sparking aid systems, traffic controlsystems, fluorescent lamps, inclementweather, air brakes, and external motorsand fans may also affect the function ofthe sensing system; this may includereduced performance or a false activation.
To help avoid personal injury, alwaysuse caution when in reverse (R) andwhen using the sensing system.
This system is not designed toprevent contact with small or movingobjects. The system is designed toprovide a warning to assist the driver indetecting large stationary objects to avoiddamaging your vehicle. The system maynot detect smaller objects, particularlythose close to the ground.
Certain add-on devices such as largetrailer hitches, bike or surfboard racksand any device that may block thenormal detection zone of the system, maycreate false beeps.
Note:Keep the sensors, located on thebumper or fascia, free from snow, ice andlarge accumulations of dirt. If the sensorsare covered, the system’s accuracy can beaffected. Do not clean the sensors withsharp objects.
Note:If your vehicle sustains damage tothe bumper or fascia, leaving it misalignedor bent, the sensing zone may be alteredcausing inaccurate measurement ofobstacles or false alarms.
Note:The sensing system cannot be turnedoff when a MyKey is present. See Principleof Operation (page 55).
Note:If you attach certain add-on devicessuch as a trailer or bike rack, the rear sensingsystem may detect that add-on device andtherefore provide warnings. It is suggestedthat you disable the rear sensing systemwhen you attach an add-on device to yourvehicle to prevent these warnings.
The sensing system warns the driver ofobstacles within a certain range of yourvehicle. The system turns on automaticallywhenever you switch the ignition on.
You can turn the system on oroff by pressing the parking aidbutton. If your vehicle does nothave a parking aid button, the system canbe switched off through the informationdisplay menu or from the pop-up messagethat appears once you shift thetransmission into reverse (R). See GeneralInformation (page 92).
If a fault is present in the system, a warningmessage appears in the informationdisplay. See Information Messages(page 96).
REAR PARKING AID (If Equipped)
The rear parking aid sensors automaticallyturn on when you shift into reverse (R).
As your vehicle moves closer to theobstacle, the rate of the audible warningincreases. When the obstacle is less than12 in (30 cm) away, the warning soundscontinuously. If the system detects anobject farther than 12 in (30 cm) from thecorners of the bumper, the tone sounds foronly three seconds. If the system detectsan approaching object the warning soundsagain.
1532018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingParking AidsE139213

Coverage area of up to 6 ft (1.8 m) fromthe rear bumper. There is decreasedcoverage area at the outer corners of thebumper.
The system detects certain objects whilethe transmission is in reverse (R) :
•Your vehicle is moving toward astationary object at a speed of 3 mph(5 km/h) or less.
•Your vehicle is not moving, but amoving object is approaching the rearof your vehicle at a speed of 3 mph(5 km/h) or less.
•Your vehicle is moving at a speed ofless than 3 mph (5 km/h) and a movingobject is approaching the rear of yourvehicle at a speed of less than 3 mph(5 km/h).
FRONT PARKING AID (If Equipped)
The front parking aid sensors automaticallyturn on when you shift into reverse (R) ora forward gear.
The front sensors are active when thetransmission is in any position other thanpark (P) and the vehicle speed is below7 mph (12 km/h).
Coverage area of up to 28 in (70 cm) fromthe front bumper. There is decreasedcoverage area at the outer corners.
The system sounds an audible warningwhen obstacles are near either bumper inthe following manner:
•Objects detected by the front sensorsare indicated by a high-pitched tonefrom the front of the vehicle.
•Objects detected by the rear sensorsare indicated by a lower pitched tonefrom the rear of the vehicle.
•The sensing system reports theobstacle which is closest to the frontor rear of the vehicle. For example, ifan obstacle is 12 in (30 cm) from thefront of the vehicle and, at the sametime, an obstacle is only 6 in (15 cm)from the rear of the vehicle, the lowerpitched tone sounds.
•An alternating warning sounds fromthe front and rear if there are objectsat both bumpers that are closer than12 in (30 cm).
The system provides warnings when yourvehicle is moving or when your vehicle isstationary and the detected obstacle isless than 12 in (30 cm) away from thebumper.
