2018 FORD FOCUS RS brake

The electronic stability control or all-wheeldrive system may automatically turn offduring extreme drifting maneuvers. If asystem turns off, the electronic stabilitycontrol warning lamp illuminates or acorresponding all-wheel drive messageappears in the information display.Continue to drive and when normal drivingresumes, the systems automatically turnon within a short period. If the electronicstability control warning lamp remainsilluminated or a warning message remainsin the information display, have yourvehicle checked as soon as possible.
Note:When using a programmed MyKeyyou cannot switch this on.
Suspension Damping
Selectable Suspension Damping
Normal
The system defaults to normal mode whenyou start the vehicle. Vehicle suspensiondamping tuned for street driving.
Sport
Vehicle suspension damping tuned forperformance driving on flat roads or fortrack use. Sport mode gives firmersuspension damping characteristics.
To select normal or sport mode, do thefollowing:
1.Press and hold the button for a shortperiod of time. The current settingappears in the information display.Release the button again to change thesetting.
Enhanced Torque VectoringControl
The system consists of two elements:
•Torque vectoring control.Automatically applies brake torque onthe inner wheel in a curve to increasetraction and decrease understeer.
•Cornering understeer control.Automatically controls the tractionresponse of your vehicle when youaccelerate on high and low frictionsurfaces.
Unlike electronic stability control,enhanced torque vectoring control doesnot slow the vehicle. The system limitsexcessive wheel slip giving greatercornering ability.
Note:The system does not disableenhanced torque vectoring control if youswitch the stability control system ortraction control system off.
In addition to enhanced torque vectoringcontrol, your vehicle also has all-wheeldrive with dynamic torque vectoring.
This feature further improves theroad-holding and traction abilities of yourvehicle. See All-Wheel Drive (page 13).

We recommend that you only operate yourvehicle at high speeds at locationsdesigned to do so safely. Your vehicle haselectronic controls that may reduce poweror limit engine speed to help reducepowertrain temperatures if required.
Note:When using your vehicle on a track,have the vehicle serviced more frequently.This recommendation may not necessarilyprotect your vehicle or engine from damagein competition conditions. Increased wearand noise to certain parts of your vehiclemay also occur, for example brakes andtires. The vehicle Warranty may not covermechanical failure or damage caused toyour vehicle as a result of track use.
Steering Assistance
Steering assistance reduces andrequires more steering effortwhen you select sport or trackfrom the drive modes menu. See DriveControl (page 20).
Prolonged track driving can result in highsteering gear temperatures. If the steeringgear overheats, you will notice a furtherincrease in steering effort being required.
High steering gear temperatures can bereduced by doing any of the following:
•Reducing vehicle speed.
•Reducing steering input.
Normal track mode steering assistancereturns when the system cools down.
Note:Steering gear cooling time can bereduced if you leave the ignition switchedon while taking a pit stop.
Before Track Use
Before operating your vehicle on a track,check the following:
•Tire pressures. See Tire Pressures(page 35). Do not exceed a cold tirepressure of 50 psi (3.4 bar) for trackuse.
•Wheels and tires for wear and damage.
•Engine coolant, engine oil and brakefluid levels.
Do not operate your vehicle on a trackwhile:
•Carrying more than two peopleincluding the driver.
•Carrying cargo in the luggagecompartment.
•Carrying cargo or loose objects insideyour vehicle.
After Track Use
After track use, leave the engine runningfor a short time to allow it to reach thenormal operating temperature. Ifconditions allow, complete a cool downlap prior to taking a pit stop. Failure toallow the engine to sufficiently cool mayresult in a high coolant temperaturewarning message appearing in theinformation display.
You must replace the rear drive unit fluidafter 500 mi (800 km) of track use, or ifthe following message appears in theinformation display, whichever occurs first.
