2018 FORD FOCUS RS Owners Manual

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).

DRIVING THROUGH WATER
Your vehicle has aerodynamic devicesattached to the underbody designed tohelp control airflow for superiorperformance. Therefore, you must beespecially careful to avoid driving throughdeep or standing water.
ENGINE OVERSPEED
WARNING
Do not operate the engine at highengine speeds while the vehicle isstationary. This can cause damagenot covered by the vehicle Warranty andcan result in serious injury.
Your vehicle has an engine speed limiterthat helps increase engine performance.A narrow red line on the tachometer faceindicates the standard maximum enginespeed. The red line thickens where theengine speed enters the overspeed limiter.
The system allows a maximum of threeseconds of engine overspeed. After this,the engine speed limiter reduces enginespeed and holds it at a predeterminedlimit. Once the engine speed drops belowthe predetermined limit, the system resetsand permits a further three seconds ofengine overspeed.
Note:Do not run the engine at high enginespeeds until it reaches the normal operatingtemperature.
ENGINE OVERBOOST
Your vehicle has an engine overboostfeature to allow additional torque delivery.The overboost feature controls a varietyof engine parameters to deliver additionaltorque. This feature widens the enginespeed range of the peak torque curve,giving maximum performance whilepassing another vehicle or launching froma standing start.
The system allows a maximum of 20seconds of engine overboost. After thisthe system reduces turbo charger boostand maximizes it at a predetermined limit.Once the turbo charger boost drops belowthe predetermined limit the system resetsand a further 20 seconds of engineoverboost is permitted.
Note:You do not need to take any actionas the system allows overboost when youdemand it.
