How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to changethe engine oil and filter based on vehicle use. Wheneverthe oil is changed, reset the system so it can calculatewhen the next oil change is required. If a situation occurswhere the oil is changed prior to a CHANGE ENGINE OILSOON message in the Driver Information Center (DIC)being turned on, reset the system.
After the oil has been changed, the CHANGE ENGINEOIL SOON message must be reset:
1. Turn the key to the ON/RUN position withoutstarting the engine.
2. Press the INFO button on the Driver InformationCenter (DIC) until OIL LIFE REMAINING isdisplayed. SeeDIC Operation and Displays onpage 4-62.
3. Press and hold the INFO RESET button until 100%is displayed. This resets the oil life indicator.
4. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOON message comesback on when the vehicle is started, the engine oillife system has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can beunhealthy for your skin and could even cause cancer.Do not let used oil stay on your skin for very long. Cleanyour skin and nails with soap and water, or a goodhand cleaner. Wash or properly dispose of clothing orrags containing used engine oil. See the manufacturer’swarnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If youchange your own oil, be sure to drain all the oil from thefilter before disposal. Never dispose of oil by putting itin the trash, pouring it on the ground, into sewers, or intostreams or bodies of water. Recycle it by taking it to aplace that collects used oil.
Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 6-12forthe location of the engine air cleaner/filter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the MaintenanceIIintervals and replace it at the first oil change after each50,000 mile (80 000 km) interval. SeeScheduledMaintenance on page 7-3for more information. If youare driving in dusty/dirty conditions, inspect the filterat each engine oil change.
6-17

{WARNING:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. If it is not there and
the engine backfires, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
Notice:If the air cleaner/filter is off, a backfire cancause a damaging engine fire. And, dirt caneasily get into the engine, which will damage it.Always have the air cleaner/filter in place when youare driving.
Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
A good time to check the automatic transmission fluidlevel is when the engine oil is changed.
Change the fluid and filter at the intervals listed inScheduled Maintenance on page 7-3, and be sure touse the transmission fluid listed inRecommended Fluidsand Lubricants on page 7-8.

If No Steam Is Coming From The
Engine Compartment
If an engine overheat warning is displayed but no steamcan be seen or heard, the problem may not be tooserious. Sometimes the engine can get a little too hotwhen the vehicle:
•Climbs a long hill on a hot day.
•Stops after high-speed driving.
•Idles for long periods in traffic.
•Tows a trailer.
If the overheat warning is displayed with no sign ofsteam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature andto the highest fan speed. Open the windows asnecessary.
3. In heavy traffic, let the engine idle in N (Neutral) whilestopped. If it safe to do so, pull off the road, shift toP (Park) or N (Neutral) and let the engine idle.
If the temperature overheat gage is no longer in theoverheat zone or an overheat warning no longer displays,the vehicle can be driven. Continue to drive the vehicleslow for about 10 minutes. Keep a safe vehicle distancefrom the car in front of you. If the warning does not comeback on, continue to drive normally.
If the warning continues, pull over, stop, and park thevehicle right away.
If there is no sign of steam, idle the engine for threeminutes while parked. If the warning is still displayed, turnoff the engine until it cools down. Also, see!OverheatedEngine Protection Operating Mode!next in this section.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and themessage ENGINE OVERHEATED STOP ENGINE isdisplayed, an overheat protection mode which alternatesfiring groups of cylinders helps prevent engine damage.In this mode, you will notice a loss in power andengine performance. This operating mode allows yourvehicle to be driven to a safe place in an emergency.Driving extended miles (km) and/or towing a trailer in theoverheat protection mode should be avoided.
Notice:After driving in the overheated engineprotection operating mode, to avoid engine damage,allow the engine to cool before attempting anyrepair. The engine oil will be severely degraded.Repair the cause of coolant loss, change the oil andreset the oil life system. SeeEngine Oil onpage 6-13.

To clean:
1. Saturate a lint-free, clean white cloth with water orclub soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rubtoward the center. Continue cleaning, using a cleanarea of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until thecleaning cloth remains clean.
5. If the soil is not completely removed, use a mildsoap solution and repeat the cleaning processthat was used with plain water.
If any of the soil remains, a commercial fabric cleaner orspot lifter may be necessary. When a commercialupholstery cleaner or spot lifter is to be used, test asmall hidden area for colorfastness first. If the locallycleaned area gives any impression that a ring formationmay result, clean the entire surface.
After the cleaning process has been completed, a papertowel can be used to blot excess moisture from thefabric or carpet.
Leather
A soft cloth dampened with water can be used toremove dust. If a more thorough cleaning is necessary,a soft cloth dampened with a mild soap solution canbe used. Allow the leather to dry naturally. Do not useheat to dry. Never use steam to clean leather. Neveruse spot lifters or spot removers on leather. Manycommercial leather cleaners and coatings that are soldto preserve and protect leather may permanentlychange the appearance and feel of the leather and arenot recommended. Do not use silicone or wax-basedproducts, or those containing organic solvents to cleanthe vehicle’s interior because they can alter theappearance by increasing the gloss in a non-uniformmanner. Never use shoe polish on leather.
TEHAMA™ Leather
The leather surface on the seat was not designed to beaggressively cleaned using any commercial product.Use a well wrung cloth dampened with water to removedust. Do not use a wet cloth or saturate the leathersurface with water. Allow the leather to dry naturally. If asoil occurs that cannot be completely removed, allowit to become part of the natural markings of the leather.The leather in the vehicle was designed to have anatural appearance and develop a more vintageappearance with use.

Rotation of New Tires
To maintain ride, handling, and performance of thevehicle, it is important that the first rotation service fornew tires be performed when they have 8 000 to13 000 km (5,000 to 8,000 miles). SeeTire Inspectionand Rotation on page 6-62.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. SeeEngine Oil onpage 6-13.An Emission Control Service.
When the Change Engine Oil Soon message displays,service is required for the vehicle as soon as possible,within the next 1 000 km/600 miles. If driving underthe best conditions, the engine oil life system might notindicate the need for vehicle service for more than ayear. The engine oil and filter must be changed at leastonce a year and the oil life system must be reset.Your dealer/retailer has trained service technicians whowill perform this work and reset the system.
If the engine oil life system is reset accidentally, servicethe vehicle within 5 000 km/3,000 miles since the lastservice. Reset the oil life system whenever the oilis changed. SeeEngine Oil Life System on page 6-16.
When the Change Engine Oil Soon message displays,certain services, checks, and inspections are required.
