WHAT IS DRIVE MODE CONTROL
Your vehicle has various drive modes thatyou can select for different drivingconditions. Depending on the drive modethat you select, the system adjusts variousvehicle settings.
HOW DOES DRIVE MODE
CONTROL WORK
Drive mode control adjusts your vehicleconfiguration for each mode you select.
Changing the drive mode adjusts thesteering effort and feel of the steeringsystem.
The stability and traction control assist yourvehicle control in adverse conditions orhigh-performance driving.
Throttle control enhances the powertrainresponse, transmission controls becomeoptimized with shift schedules, andfour-wheel drive settings are optimized andtuned to each mode.
Changing the drive mode can engage ordisengage the electronic locking differentials.
Changing the drive mode changes thefour-wheel drive mode to the default settingfor the selected drive mode.
Note:The system has diagnostic checks thatcontinuously monitor the system for properoperation. If a mode is unavailable due to asystem fault, the drive mode system defaultsto normal. When the system defaults tonormal, the driveline settings remain thesame as prior to the system fault.
Note:The system reverts to the normalmode each time you start your vehicle. Atstartup the system also displays a prompton the instrument cluster display that givesyou the option to return to the previouslyselected drive mode during the last ignitioncycle. If you select yes, the system returnsto the last selected drive mode and thedefault driveline settings associated withthat mode. If you select no, the systemremains in normal mode and the drivelinesettings remain the same as selected in theprior ignition cycle. If you do not select yesor no, the system stays in normal mode andthe driveline settings remain the same asselected in the prior ignition cycle.

COLD WEATHER PRECAUTIONS
The functional operation of somecomponents and systems can be affected attemperatures below approximately -13°F(-25°C).
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.
On ice and snow, you should drive moreslowly than usual. Your vehicle has a fourwheel anti-lock brake system, do not pumpthe brake pedal. See Anti-Lock BrakingSystem Limitations (page 232).
BREAKING-IN
Your vehicle requires a break-in period. Forthe first 1,000 mi (1,600 km), avoid driving athigh speeds, heavy braking, aggressiveshifting or using your vehicle to tow. Duringthis time, your vehicle may exhibit someunusual driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuelconsumption:
•Drive smoothly, accelerate gently andanticipate the road ahead to avoid heavybraking.
•Regularly check your tire pressures andmake sure that they are inflated to thecorrect pressure.
•Follow the recommended maintenanceschedule and carry out therecommended checks.
•Plan your journey and check the trafficbefore you set off. It is more efficient tocombine errands into a single tripwhenever possible.
•Avoid idling the engine in cold weatheror for extended periods. Start the engineonly when you are ready to set off.
•Do not carry unnecessary weight in yourvehicle as extra weight wastes fuel.
•Do not add unnecessary accessories tothe exterior of your vehicle, for examplerunning boards. If you use a roof rack,remember to fold it down or remove itwhen not in use.
•Do not shift into neutral when you arebraking or when your vehicle is slowingdown.
•Shut all windows when driving at highspeeds.
•Switch off all electric systems when notin use, for example air conditioning. Makesure that you unplug any accessoriesfrom the auxiliary power points when notin use.

DRIVING IN SPECIAL CONDITIONS
DRIVING THROUGH MUD AND WATER
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even all-wheel drive and four-wheeldrive vehicles can lose traction in mud. Ifyour vehicle slides, steer in the direction ofthe slide until you regain control of yourvehicle. After driving through mud, clean offresidue stuck to rotating driveshafts and tires.Excess residue can cause an imbalance thatcould damage drive components.
Note:If your vehicle gets stuck in mud, itcould be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature, asdamage to the transmission could occur.
Note:Do not rock your vehicle for more thana minute, as damage to the transmissionand tires could occur or the engine couldoverheat.
Water
If you must drive though deep water, driveslowly. The water could limit traction or brakecapability. See Driving Through ShallowWater (page 386).
When driving though water, determine thedepth and avoid water higher than the centerof the wheel.
Once through water, always try the brakes.Wet brakes do not stop your vehicle asquickly as dry brakes. Apply light pressureto the brake pedal while slowly moving thevehicle to dry the brakes.
Note:Driving through deep water couldcause damage to the transmission. If thefront or rear axle is submerged in water,have the axle lubricant and power transferunit lubricant checked and changed ifnecessary.
DRIVING ON HILLY OR SLOPINGTERRAIN
WARNING: Extreme care should beused when steering the vehicle in reversedown a slope so as not to cause thevehicle to swerve out of control.
Although natural obstacles could make itnecessary to travel diagonally up or down ahill or steep incline, you should try to drivestraight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you can use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.

2023 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202207, DOMDriving Hints

Apply just enough power to the wheels toclimb the hill. Too much power causes thetires to slip, spin or lose traction, and youcould lose control of your vehicle. Whendescending a steep hill, do not descend thehill in neutral. Avoid sudden hard braking tokeep the front wheels rolling and to maintainyour vehicle's steering.
Note:Your vehicle has anti-lock brakes,apply the brakes steadily. Do not pump thebrakes.
Note:If your vehicle gets stuck driving onhilly or sloping terrain, it could be rocked outby shifting between forward and reversegears, stopping between shifts in a steadypattern. Press lightly on the accelerator ineach gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature, asdamage to the transmission could occur.
Note:Do not rock your vehicle for more thana minute, as damage to the transmissionand tires could occur or the engine couldoverheat.
DRIVING IN SAND
When driving over sand, try to keep all fourwheels on the most solid area of the trail. Steadily drive through the terrain. Apply theaccelerator slowly and avoid excessivewheel slip. Do not drive your vehicle in deepsand for an extended period of time. Thiscould overheat the system. A messageappears in the instrument cluster display.
