COLD WEATHER PRECAUTIONS
The functional operation of somecomponents and systems can be affected attemperatures below approximately -13°F(-25°C).
BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). During thistime, your vehicle may exhibit some unusualdriving 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 315).
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.
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.

DRIVING THROUGH SHALLOW
WATER
WARNING: Do not attempt to crossa deep or flowing body of water. Failure tofollow this instruction could result in theloss of control of your vehicle, personalinjury or death.
Note:Driving through standing water cancause vehicle damage.
Note:Engine damage can occur if waterenters the air filter.
Before driving through standing water, checkthe depth. Never drive through water that ishigher than the bottom of the front rockerarea of your vehicle.
When driving through standing water, drivevery slowly and do not stop your vehicle. Your brake performance and traction couldbe limited. After driving through water andas soon as it is safe to do so:
•Lightly press the brake pedal to dry thebrakes and to check that they work.
•Turn the steering wheel to check that thesteering power assist works.
Check the function of the following:

12 Volt Battery
•When storing your vehicle for greaterthan 30 days the state of charge shouldbe approximately 50%. Additionally, werecommend disconnecting the 12vbattery which will reduce system loadson the battery.
•Check and recharge as necessary. Keepconnections clean.
Note:It is necessary to reset memoryfeatures if you disconnect the battery cables.
Brakes
Make sure the brakes and parking brakerelease fully.
Note:If you intend on parking your vehiclefor an extended period after cleaning thewheels with a wheel cleaner, drive yourvehicle for a few minutes before doing so toreduce the risk of increased corrosion of thebrake discs, brake pads and linings.
Tires
Maintain recommended air pressure.

REMOVING YOUR VEHICLE FROM
STORAGE
When your vehicle is ready to come out ofstorage, do the following:
•We recommend that you change theengine oil before you use your vehicleagain.
•Wash your vehicle to remove any dirt orgrease film build-up on window surfaces.
•Check windshield wipers for anydeterioration.
•Check the underhood for any foreignmaterials such as mice or squirrel nests.
•Check the exhaust for any foreignmaterials.
•Check tire pressures and set tire inflationper the Tire Label.
•Check brake pedal operation. Corrodedbrake rotors could cause brake noise.Drive your vehicle and gently apply andrelease the brakes repeatedly over a10-minute drive to reduce the corrosionfrom the brakes.
•Check fluid levels (including coolant, oiland gas) to make sure there are no leaks,and fluids are at recommended levels.
•If you remove the battery, clean thebattery cable ends and check fordamage.
Contact an authorized dealer if you have anyconcerns or issues.

LOCATING THE TIRE LABEL
The tire label or safety certification labelis on the driver side B-pillar or the edgeof the driver door. It contains informationon the recommended front and rear tireinflation pressures. See Locating theSafety Compliance Certification Labels(page 297).
DEPARTMENT OF
TRANSPORTATION UNIFORM TIRE
QUALITY GRADES
Tire Quality Grades apply to newpneumatic passenger car tires. TheQuality grades can be found whereapplicable on the tire sidewall betweentread shoulder and maximum sectionwidth. For example: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that the UnitedStates Department of Transportation hasset.
Tire Quality Grades apply to newpneumatic passenger car tires. They donot apply to deep tread, winter-typesnow tires, space-saver or temporaryuse spare tires, light truck or LT typetires, tires with nominal rim diameters of10 to 12 inches or limited production tires
as defined in Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department of Transportation Tirequality grades: The U.S. Department ofTransportation requires us to give youthe following information about tiregrades exactly as the government haswritten it.
Treadwear
The treadwear grade is a comparativerating based on the wear rate of the tirewhen tested under controlled conditionson a specified government test course.For example, a tire graded 150 wouldwear 1½ times as well on thegovernment course as a tire graded 100.The relative performance of tiresdepends upon the actual conditions oftheir use, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.
Traction AA A B C
WARNING: The traction gradeassigned to this tire is based onstraight-ahead braking traction tests,and does not include acceleration,cornering, hydroplaning or peaktraction characteristics.
375
2023 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202207, DOMWheel and Tire InformationE142542

The traction grades, from highest tolowest are AA, A, B, and C. The gradesrepresent the tire’s ability to stop on wetpavement as measured under controlledconditions on specified government testsurfaces of asphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING: The temperaturegrade for this tire is established for atire that is properly inflated and notoverloaded. Excessive speed,underinflation, or excessive loading,either separately or in combination,can cause heat buildup and possible
tire failure.
The temperature grades are A (thehighest), B and C, representing the tire’sresistance to the generation of heat andits ability to dissipate heat when testedunder controlled conditions on aspecified indoor laboratory test wheel.Sustained high temperature can cause
the material of the tire to degenerateand reduce tire life, and excessivetemperature can lead to sudden tirefailure. The grade C corresponds to alevel of performance which allpassenger car tires must meet under theFederal Motor Vehicle Safety StandardNo. 139. Grades B and A representhigher levels of performance on thelaboratory test wheel than the minimumrequired by law.
INFORMATION ON THE TIRE
SIDEWALL
Both United States and Canada Federalregulations require tire manufacturersto place standardized information on thesidewall of all tires. This informationidentifies and describes the fundamentalcharacteristics of the tire and alsoprovides a U.S. DOT Tire IdentificationNumber for safety standard certificationand in case of a recall.
