GLOSSARY OF TIRE
TERMINOLOGY
*Tire label: A label showing the originalequipment tire sizes, recommendedinflation pressure and the maximumweight the vehicle can carry.
*Tire Identification Number (TIN): Anumber on the sidewall of each tireproviding information about the tirebrand and manufacturing plant, tire sizeand date of manufacture. Also referredto as DOT code.
*Inflation pressure: A measure of theamount of air in a tire.
*Standard load: A class of P-metric orMetric tires designed to carry amaximum load at set pressure. Forexample: For P-metric tires 35 psi(2.4 bar) and for Metric tires 36 psi(2.5 bar). Increasing the inflationpressure beyond this pressure will notincrease the tire’s load carryingcapability.

*Recommended inflation pressure: Thecold inflation pressure found on the
Safety Compliance Certification Label(affixed to either the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver's seating position), or Tire Labellocated on the B-Pillar or the edge of thedriver door.
* B-pillar: The structural member at theside of the vehicle behind the front door.
*Bead area of the tire: Area of the tirenext to the rim.
* Sidewall of the tire: Area between thebead area and the tread.
*Tread area of the tire: Area of theperimeter of the tire that contacts theroad when mounted on the vehicle.
*Rim: The metal support (wheel) for atire or a tire and tube assembly uponwhich the tire beads are seated.

2023 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202207, DOMWheel and Tire Information
It is recommended that the two fronttires or two rear tires generally bereplaced as a pair if the worn tires stillhave usable depth.
To avoid potential All-Wheel Drive (AWD)malfunction or (AWD) system damage,it is recommended to replace all fourtires rather than mixing significantly worntires with new tires.
The tire pressure sensors mounted inthe wheels (originally installed on yourvehicle) are not designed to be used inaftermarket wheels.
The use of wheels or tires notrecommended may affect the operationof your tire pressure monitoring system.
If the tire pressure monitoring system
indicator is flashing, your system ismalfunctioning. Your replacement tiremight be incompatible with your tirepressure monitoring system, or somecomponent of the system may bedamaged.
Age
WARNING: Tires degrade overtime depending on many factors suchas weather, storage conditions, andconditions of use (load, speed, inflationpressure) the tires experiencethroughout their lives.In general, tires should be replacedafter six years regardless of treadwear. However, heat caused by hotclimates or frequent high loadingconditions can accelerate the agingprocess and may require tires to bereplaced more frequently.You should replace your spare tirewhen you replace the road tires orafter six years due to aging even if it
has not been used.
U.S. DOT Tire Identification Number
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.
This begins with the letters DOT andindicates that the tire meets all federalstandards. The next two numbers orletters are the plant code designatingwhere it was manufactured, the next twoare the tire size code and the last fournumbers represent the week and yearthe tire was built. For example, the
numbers 317 mean the 31st week of1997. After 2000, the numbers go to fourdigits. For example, 2501 means the25th week of 2001. The numbers inbetween are identification codes usedfor traceability. This information is usedto contact customers if a tire defectrequires a recall.

USING SNOW CHAINS
WARNING: Do not exceed 30 mph(50 km/h). Failure to follow this instructioncould result in the loss of control of yourvehicle, personal injury or death.
WARNING: Do not use snow chainson snow-free roads.
WARNING: Only fit snow chains tospecified tires.
WARNING: If your vehicle is fittedwith wheel trims, remove them beforefitting snow chains.
WARNING: Wheels and tires mustbe the same size, load index and speedrating as those originally fitted on thevehicle. Use of any other tire or wheel canaffect the safety and performance of yourvehicle. Additionally, the use ofnon-recommended tires and wheels cancause steering, suspension, axle, transfercase or power transfer unit failure. Follow
the recommended tire inflation pressuresfound on the Safety ComplianceCertification label, or the Tire Label on theB-Pillar or the edge of the driver door.Failure to follow this instruction could resultin loss of vehicle control, vehicle rollover,or personal injury or death.
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.
Only use snow chains on the front wheels.Install snow chains in pairs. Do not useself-tensioning snow chains.
Only use snow chains on the followingspecified tire size:
•235/60R18 all season tires.
•Only use ultra low profile snow chainsthat are 10 mm or less.
We recommend you use steel wheels of thesame size and specification if snow chainsare required because chains may chipaluminum wheels.
Follow these guidelines when using snowtires and traction devices:
•If possible, avoid fully loading yourvehicle.
•Purchase snow chains from amanufacturer that clearly labels body totire dimension restrictions.
•When driving with snow chains do notexceed 30 mph (50 km/h) or themaximum speed recommended by thechain manufacturer, whichever is less.
•Drive cautiously. If you hear the snowchains rub or bang against the vehicle,stop and tighten them. If this does notwork, remove the snow chains to preventvehicle damage.

CHECKING THE TIRE PRESSURES
Safe operation of your vehicle requiresthat your tires are properly inflated.Every day before you drive, check yourtires.
At least once a month and before longtrips, inspect each tire and check the tirepressure with a tire gauge. Inflate alltires to the recommended inflationpressure. See Inflating the Tires (page386).
INFLATING THE TIRES
WARNING: Under-inflation is themost common cause of tire failures
and may result in severe tire cracking,tread separation or blowout, withunexpected loss of vehicle control andincreased risk of injury. Under-inflationincreases sidewall flexing and rollingresistance, resulting in heat buildup
and internal damage to the tire. It alsomay result in unnecessary tire stress,irregular wear, loss of vehicle controland accidents. A tire can lose up tohalf of its air pressure and not appearto be flat!
WARNING: Do not use the tirepressure displayed in the informationdisplay as a tire pressure gauge.Failure to follow this instruction couldresult in personal injury or death.
Use the recommended cold inflationpressure for optimum tire performanceand wear. Under-inflation orover-inflation may cause uneventreadwear patterns.
Inflate your tires to the recommendedinflation pressure even if it is less thanthe maximum inflation pressureinformation found on the tire. You canfind the tire label with the recommendedtire inflation pressure next to the tire sizeon the B-Pillar or the edge of the driverdoor.
The recommended tire inflation pressureis also found on the Safety ComplianceCertification Label, affixed to either thedoor hinge pillar, door-latch post, or thedoor edge that meets the door-latch onthe B-pillar, or on the edge of the driverdoor.
Failure to follow the tire pressurerecommendations can cause uneventreadwear patterns and adversely affectthe way your vehicle handles.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoringsystem measures the vehicle's tirepressures. A warning lampilluminates if one or more tires aresignificantly underinflated or if there is asystem malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW
WARNING: Under-inflation is themost common cause of tire failures andmay result in severe tire cracking, treadseparation or blowout, with unexpectedloss of vehicle control and increased riskof injury. Under-inflation increases sidewallflexing and rolling resistance, resulting in
heat buildup and internal damage to thetire. It also may result in unnecessary tirestress, irregular wear, loss of vehiclecontrol and accidents. A tire can lose upto half of its air pressure and not appearto be flat!
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance Certification Label(on the door hinge pillar, door-latch postor the door edge that meets the door-latchpost, next to the driver seat) or the TireLabel on the B-Pillar or the edge of thedriver door.
Each tire, including the spare (if provided),should be checked monthly when cold andinflated to the inflation pressurerecommended by the vehicle manufactureron the vehicle placard or tire inflationpressure label. (If your vehicle has tires of adifferent size than the size indicated on thevehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.

CHANGING A FLAT TIRE
WARNING: If the tire pressuremonitor sensor becomes damaged it maynot function.
If you get a flat tire while driving, do not applythe brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safe placeon the side of the road.
Have a flat serviced by an authorized dealerin order to prevent damage to the tirepressure monitoring system sensors. SeeTire Pressure Monitoring System Overview(page 396). Replace the spare tire with a roadtire as soon as possible. During repairing orreplacing of the flat tire, have an authorizeddealer inspect the tire pressure monitoringsystem sensor for damage.
Note:The use of tire sealant could damageyour tire pressure monitoring sensor andshould only be used in roadsideemergencies. If you must use a sealant, usethe Tire Mobility Kit sealant. Replace the tirepressure monitoring system sensor andvalve stem on the wheel by an authorizeddealer after use of the sealant.
Note:The tire pressure monitoring systemindicator light will illuminate when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on the vehicle.
