Note:Your vehicle may be equippedwith a dissimilar spare wheel and tireassembly. A dissimilar spare wheel andtire assembly is defined as a sparewheel and tire assembly that is differentin brand, size or appearance from theroad tires and wheels. If you have adissimilar spare wheel and tire assemblyit is intended for temporary use only andshould not be used in a tire rotation.
Note:After having your tires rotated,inflation pressure must be checked andadjusted to the vehicle requirements.
Rotating your tires at the recommendedinterval (as indicated in the ScheduledMaintenance chapter) will help your tireswear more evenly, providing better tireperformance and longer tire life.
Rear-wheel drive vehicles andfour-wheel drive vehicles (front tires atleft of diagram)
Sometimes irregular tire wear can becorrected by rotating the tires.
USING SNOW CHAINS
WARNING: Snow tires must be thesame size, load index and speed rating asthose originally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety and performanceof your vehicle, which could result in anincreased risk of loss of control, vehiclerollover, personal injury and death.Additionally, the use of non-recommended
tires and wheels can cause steering,suspension, axle, transfer case or powertransfer unit failure. Follow the Fordrecommended tire inflation pressure foundon the Safety Compliance CertificationLabel (on the door hinge pillar, door latchpost or the door edge that meets the doorlatch post, next to the driver seat), or TireLabel on the B-Pillar or the edge of thedriver door. Failure to follow the tirepressure recommendations can causeuneven treadwear patterns and adverselyaffect the way your vehicle handles.
Note:The suspension insulation andbumpers will help prevent vehicle damage.Do not remove these components from yourvehicle when using snow tires and chains.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you need touse cables, it is recommended that steelwheels (of the same size and specifications)be used, as cables may chip aluminumwheels.

When the oil change message appears inthe information display, it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 mi (800 km)of the message appearing. Make sure youreset the Intelligent Oil-Life Monitor aftereach oil change. See Oil Change IndicatorReset (page 365).
