2019 LINCOLN NAVIGATOR Owners Manual

When climbing a steep slope or hill, start ina lower gear rather than downshifting to alower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turn aroundbecause this could cause vehicle roll over.It is better to reverse back to a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power causes thetires to slip, spin or lose traction, resulting inloss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating. Donot descend in neutral. Disengage overdriveor move the transmission selector lever to alower gear. When descending a steep hill,avoid sudden hard braking as you could losecontrol. The front wheels have to be turningin order to steer your vehicle.
If your vehicle has anti-lock brakes, apply thebrakes steadily. Do not pump the brakes.
Driving on Snow and Ice
WARNING: If you are driving inslippery conditions that require tire chainsor cables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear endof your vehicle slides while cornering, steerin the direction of the slide until you regaincontrol of your vehicle.
Note:Excessive tire slippage can causetransmission damage.
Four-wheel drive vehicles have advantagesover two-wheel drive vehicles in snow andice but can skid like any other vehicle.Should you start to slide when driving onsnowy or icy roads, turn the steering wheelin the direction of the slide until you regaincontrol.
Avoid sudden applications of power andquick changes of direction on snow and ice.Apply the accelerator slowly and steadilywhen starting from a full stop.
Avoid sudden braking. Although a four-wheeldrive vehicle may accelerate better than atwo-wheel drive vehicle in snow and ice, itdoes not stop any faster as braking occursat all four wheels. Do not becomeoverconfident in any road condition.
Make sure you allow sufficient distancebetween you and other vehicles for stopping.Drive slower than usual and consider usingone of the lower gears. In emergencystopping situations, apply the brake steadily.Do not pump the brake pedal. See Hints onDriving With Anti-Lock Brakes (page 226).

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 385).
See Warning Lamps andIndicators (page 114).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal becomesstuck or entrapped, apply steady and firmpressure to the brake pedal to slow thevehicle and reduce engine power. If youexperience this condition, apply the brakesand bring your vehicle to a safe stop. Switchthe engine off, move the transmission to park(P) and apply the parking brake. Inspect theaccelerator pedal and the area around it forany items or debris that may be obstructingits movement.If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate at whichyou press the brake pedal. It providesmaximum braking efficiency as long as youpress the pedal. Emergency brake assistcan reduce stopping distances in criticalsituations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarily illuminateswhen you switch the ignition on. Ifthe light does not illuminate duringstart up, remains on or flashes, the anti-lockbraking system may be disabled. Have thesystem checked by an authorized dealer. Ifthe anti-lock brake system is disabled,normal braking is still effective.
If the brake warning lampilluminates with the parking brakereleased, have your brake systemserviced immediately.
It also illuminates momentarily when youswitch the ignition on to confirm the lamp isfunctional. If it does not illuminate when youswitch the ignition on, or begins to flash atany time, have the system checked by anauthorized dealer.

HILL START ASSIST
WARNING: The system does notreplace the parking brake. When you leaveyour vehicle, always apply the parkingbrake and shift the transmission into park(P) for automatic transmission or first gearfor manual transmission.
WARNING: You must remain in yourvehicle when the system turns on. At alltimes, you are responsible for controllingyour vehicle, supervising the system andintervening, if required. Failure to take caremay result in the loss of control of yourvehicle, serious personal injury or death.
Note:If the engine is revved excessively, orif a malfunction is detected, the system willbe deactivated.
The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system is active, your vehicle willremain stationary on the slope for two tothree seconds after you release the brakepedal. This allows you time to move yourfoot from the brake to the accelerator pedal. The brakes release automatically when theengine has sufficient torque to prevent yourvehicle from rolling down the grade. This isan advantage when pulling away on a slope,for example from a car park ramp, trafficlights or when reversing uphill into a parkingspace.
The system will activate automatically on anyslope that will cause significant vehiclerollback. For vehicles with a manualtransmission, you can switch this feature offusing the information display. SeeInformation Displays (page 120). The systemwill remain on or off depending on how itwas last set.
Note:There is no warning lamp to indicatethe system is either on or off.
Note:If your vehicle is equipped with AutoHold, Hill Start Assist will not be availablewhile Auto Hold is active.
Using Hill Start Assist
1. Bring your vehicle to a completestandstill. Keep the brake pedal pressedand select an uphill gear (for example,drive (D) or first (1) when facing uphill orreverse (R) when facing downhill).
2. If the sensors detect that your vehicle ison a slope, the system will activateautomatically.
3. When you remove your foot from thebrake pedal, your vehicle will remain onthe slope without rolling away for abouttwo or three seconds. This hold time willautomatically be extended if you are inthe process of driving off.
4. Drive off in the normal manner. Thebrakes will release automatically.
Switching the System On and Off
You can switch this feature on or off if yourvehicle is equipped with a manualtransmission and an information display. SeeGeneral Information (page 120). The systemremembers the last setting when you startyour vehicle.
