WARNING
•No objects that add to the total weight on the seat should be placed on the frontpassenger's seat. If a child is seated inthe front passenger's seat with any addi-tional weight, this extra weight couldcause the OWS system to enable the air-bag, which might cause it to deploy in theevent of a collision, thereby injuring thechild.
• The seat belt should never be wrappedaround an object on the front passeng-er's seat. This could interfere with theOWS system's function.
• The front passenger's seat belt shouldnever be used in a way that exerts morepressure on the passenger than normal.This could increase the pressure exertedon the weight sensor by a child, andcould result in the airbag being enabled,which might cause it to deploy in theevent of a collision, thereby injuring thechild.
WARNING
• Keep the following points in mind with respect to the OWS system. Failure tofollow these instructions could adverselyaffect the system's function and result inserious injury to the occupant of the frontpassenger's seat:
• The full weight of the front seat passen-ger should always be on the seat cushion.The passenger should never lift him/herself off the seat cushion using thearmrest in the door or the center console,by pressing the feet on the floor, by sit-ting on the edge of the seat cushion, orby pressing against the backrest in a waythat reduces pressure on the seat cush-ion. This could cause OWS to disable thefront, passenger's side airbag.
WARNING
•
Do not place any type of object on the front passenger's seat in such a way thatjamming, pressing, or squeezing occursbetween the object and the front seat,other than as a direct result of the correctuse of the Automatic Locking Retractor/Emergency Locking Retractor (ALR/ELR)seat belt.
• No objects should be placed under thefront passenger's seat. This could inter-fere with the OWS system's function.

•Stop the engine, put the gear selector in P
, and apply the parking brake when
loading or unloading long objects.
• The vehicle's driving characteristics may change depending on the weight and dis-tribution of the load.
• A 44-pound (20 kg) object produces aforce of 2,200 pounds (1,000 kg) in ahead-on collision at 30 mph (50 km/h).
• The cargo compartment and rear seatshould not be loaded to a level higherthan 2 in. (5 cm) below the upper edge ofthe rear side windows. Objects placedhigher than this level could impede thefunction of the Inflatable Curtain.
WARNING
• Cover sharp edges on long loads to help prevent injury to occupants. Secure theload to help prevent shifting during sud-den stops.
• Always secure large and heavy objectswith a seat belt or cargo retaining straps.
• Always secure the load to help prevent itfrom moving in the event of sudden stops.
• Switch off the engine, apply the parking brake and put the gear selector in
P
when loading and unloading the vehicle.
Extra loading spaceThe vehicle has flexible cargo capacity that makes it possible to load and secure largeobjects and loading capacity can be increasedwhen needed. By folding down the rear seat backrests, the cargo capacity of the vehicle increases consider-ably. Use the load anchoring eyelets or the gro-cery bag holder to secure objects. The hatch in the center section of the rear seat backrest * can be opened without folding the
backrest down to transport long objects such as skis, etc. The jack *, tire sealing system and tools can be
found under the floor of the trunk.
WARNING
• Boxes, suitcases, etc. wedged behind the front seats could impede the function ofthe Whiplash Protection System.
• If the rear seat backrests are foldeddown, cargo must be secured to preventit from sliding forward against the frontseat backrests in the event of a collisionfrom the rear. This could interfere withthe action of the Whiplash ProtectionSystem.

Tire sidewall designations
The following information can be found on a tire's sidewall.
Federal law mandates that tire manufacturers place standardized information on the sidewall ofall tires (see the illustration). The vehicle has been certified with certain combi- nations of wheels and tires. The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire desig- nation is an example only and that this par-
ticular tire may not be available on your vehi- cle.
1. 215 : the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its width
in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 5
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example, a
load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum
speed at which the tire is designed to bedriven for extended periods of time, carryinga permissible load for the vehicle, and withcorrect inflation pressure. For example, Hindicates a speed rating of 130 mph(210 km/h).

NOTE
The tire's load index and speed rating may not appear on the sidewall because they arenot required by law.
7.M+S or M/S = Mud and Snow, AT = All Ter-
rain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and
indicates that the tire meets all federalstandards. The next two numbers or lettersare the plant code where it was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was built. For example,1510 means that the tire was manufacturedduring week 15 of 2010. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9. Tire Ply Composition and Material Used :
Indicates the number of plies indicates or thenumber of layers of rubber-coated fabric inthe tire tread and sidewall. Tire manufactur-ers also must indicate the ply materials in thetire and the sidewall, which include steel,nylon, polyester, and others.
10. Maximum Load : Indicates the maximum
load in pounds and kilograms that can becarried by the tire. Refer to the vehicle's tire information placard located on the B-Pillarfor the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperaturegrades .
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This limit is setby the tire manufacturer.
Speed SymbolA tire's Speed Symbol (SS) indicates the maxi-mum speed for which the tire has been certifiedand should be at least equivalent to the vehicle'stop speed. Winter tires, with our without studs, are excep- tions and may use a lower SS. When winter tiresare installed, the vehicle may not be driven fasterthan the tires' SS. The vehicle's speed should always be determined by the posted speed limit and traffic and roadconditions, not the tire's SS. The following table indicates the maximum per- missible speed for each SS.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES .
Quality grades can be found, where applica- ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.
TRACTIONThe traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance. The tractiongrade assigned to this tire is based on braking (straight-ahead) traction tests and is not a meas-ure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.

PRACTICAL INFORMATION
98temperature drop causes a corresponding drop of 1 psi (7 kPa) in inflation pressure. Check yourtire pressures frequently and adjust them to theproper pressure, which can be found on the vehi-cle's tire information placard or certification label. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. The tiresare hot from driving and it is normal for pressuresto increase above recommended cold pressures.A hot tire at or below recommended cold inflationpressure could be significantly under-inflated.
Recommended inflation pressures
Tire inflation placard
A tire inflation pressure placard is located on the driver's side B-pillar (the structural member at theside of the vehicle, at the rear of the driver's dooropening). This placard indicates the designation
of the factory-mounted tires on your vehicle, aswell as load limits and inflation pressure.
NOTE
•
The placard shown indicates inflation pressure for the tires installed on thevehicle at the factory only.
• A certain amount of air seepage from thetires occurs naturally and tire pressurefluctuates with seasonal changes in tem-perature. Always check tire pressure reg-ularly.
•Use a tire gauge to check the tire inflation pressure, including the spare 6
, at least once
a month and before long trips. You are strongly urged to buy a reliable tire pressuregauge, as automatic service station gaugesmay be inaccurate.
• Use the recommended cold inflation pres-sure for optimum tire performance and wear.
• Under-inflation or over-inflation may causeuneven treadwear patterns.
Checking tire pressure1. Remove the cap from the valve on one tire,
then firmly press the tire gauge onto thevalve. 2. Add air to reach the recommended air pres-
sure.
3. Replace the valve cap.
CAUTION
• After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded that could puncture the tire and cause an air leak.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregulari-ties.
6. Repeat this procedure for each tire, including the spare.

Tire Pressure Monitoring System (TPMS) TPMS provides a warning if inflation pressure in one or more tires is too low. It also uses a sym-bol (called a telltale) that will flash for60 seconds and then glow steadily if there is asystem malfunction.
TPMS uses the rotational speed of the tires in combination with signal analysis of the ABS sen-sor signals to determine if they are properly infla-ted. When a tire is under-inflated, its diameter(and consequently also its rotational speed)changes. By comparing the individual tires witheach other it is possible to determine if one ormore tires are under inflated. If inflation pressureis too low, an indicator symbol will illuminate inthe instrument panel and a text message will bedisplayed.
Symbol
Explanation
The symbol illuminates to indicate low tire inflation pressure. If a malfunction occurs in the sys- tem, the tire pressure warning sym-bol will flash for approximately1 minute and then remain illumi-nated.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehi-cle manufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tiresof a different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflation pres-sure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure telltale.
