On some vehicles, when the systemhas calculated that oil life has beendiminished, a CHANGE ENGINEOIL SOON message comes on toindicate that an oil change isnecessary. SeeEngine OilMessages0134.Changetheoilassoon as possible within the next1000km (600mi). It is possible that,if driving under the best conditions,the oil life system might indicate thatan oil change is not necessary forup to a year. The engine oil andfilter must be changed at least onceayearand,atthistime,thesystemmust be reset. For vehicles withoutthe CHANGE ENGINE OIL SOONmessage, an oil change is neededwhen the OIL LIFE REMAININGpercentage is near 0%. Your dealerhas trained service people who willperform this work and reset the
system. It is also important to checkthe oil regularly over the course ofan oil drain interval and keep it atthe proper level.
If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.

If using winter tires:
.Use tires of the same brand andtread type on all four wheelpositions.
.Use only radial ply tires of thesame size, load range, andspeed rating as the originalequipment tires.
Winter tires with the same speedrating as the original equipment tiresmay not be available for H, V, W, Y,and ZR speed rated tires. If wintertires with a lower speed rating arechosen, never exceed the tire'smaximum speed capability.
All-Terrain Tires
This vehicle may have all-terraintires. These tires provide goodperformance on most road surfaces,weather conditions, and for off-roaddriving. SeeOff-Road Driving0218.
The tread pattern on these tires maywear more quickly than other tires.Consider rotating the tires morefrequently than at 12 000 km(7,500 mi) intervals if irregular wearis noted when the tires areinspected. SeeTireInspection0329.
