3. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOONmessage comes back on when thevehicle is started, the engine oil lifesystem has not reset. Repeat theprocedure.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to checkthe transmission fluid level. The onlyreason for fluid loss is atransmission leak or overheatedtransmission. If a small leak issuspected, use the followingprocedures to check the fluid level.However, if there is a large leak, itmay be necessary to have thevehicle towed to a dealer and haveit repaired before driving the vehiclefurther.
Change the fluid and filter at theintervals listed inMaintenanceSchedule0297,andbesuretousethe transmission fluid listed inRecommended Fluids andLubricants0305.
How to Check Automatic
Transmission Fluid
Because this operation can bedifficult, it is recommended to havethis check done at your dealer,which can monitor the transmissiontemperature. The transmission fluidlevel increases with temperature. Toobtain a highly accurate fluid levelcheck, the transmission temperaturemust be measured.
If it is decided to check the fluidlevel, be sure to follow all theinstructions here, or a false readingon the dipstick may occur.

Light Truck (LT-Metric) Tire
(1) Light Truck (LT-Metric)
Tire:The United States version
of a metric tire sizing system.
The letters LT as the first two
characters in the tire size mean
alighttrucktireengineeredto
standards set by the U.S. Tire
and Rim Association.
(2) Tire Width:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio:Atwo-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 75, as shown in
item 3 of the light truck
(LT-Metric) tire illustration, it
would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code:Aletter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Load Range:Load Range.
(7) Service Description:The
service description indicates the
load index and speed rating of a
tire. If two numbers are given as
in the example, 120/116, then
this represents the load index for
single versus dual wheel usage
(single/dual). The speed rating is
the maximum speed a tire is
certified to carry a load. This
