Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock BrakeSystem (ABS), an advancedelectronic braking system that helpsprevent a braking skid.
When the vehicle begins to driveaway, ABS checks itself.Amomentarymotororclickingnoisemay be heard while this test is goingon, and it may even be noticed thatthe brake pedal moves a little. Thisis normal.
If there is a problem with ABS, thiswarning light stays on. SeeAntilockBrake System (ABS) WarningLight0104.
If driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking toavoid a sudden obstacle, acomputer senses the wheels areslowing down. If one of the wheelsis about to stop rolling, the computerwill separately work the brakes ateach wheel.
ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpyou steer around the obstacle whilebraking hard.
As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.
Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.

To i d e n t i f y t h e t r a i l e r i n g c a p a c i t y o fthe vehicle, read the information in“Weight of the Trailer”following.
Trailering is different than justdriving the vehicle by itself.Trailering means changes inhandling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.
The following information has manytime-tested, important trailering tipsand safety rules. Many of these areimportant for your safety and that of
your passengers. So please readthis section carefully before pulling atrailer.
Weight of the Trailer
Safe trailering requires monitoringthe weight, speed, altitude, roadgrades, outside temperature, andhow frequently the vehicle is used topull a trailer are all important. Takeinto consideration any specialequipment on the vehicle, and theamount of tongue weight the vehiclecan carry. See“Weight of the TrailerTo n g u e”later in this section.
Maximum trailer weight is calculatedassuming only the driver is in thetow vehicle and it has all therequired trailering equipment. Theweight of additional optionalequipment, passengers,and cargo inthe tow vehicle must be subtractedfrom the maximum trailer weight.
Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle model andoptions.

engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty.
Viscosity Grade
Use SAE 5W-30 viscosity gradeengine oil.
Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below✓29 °C(✓20 °F), an SAE 0W-30 oil may beused. An oil of this viscosity gradewill provide easier cold starting forthe engine at extremely lowtemperatures. When selecting an oilof the appropriate viscosity grade, itis recommended to select an oil ofthe correct specification. See“Specification”earlier in this section.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. Therecommended oils meeting thedexos1 specification are all that isneeded for good performance andengine protection.
Engine oil system flushes are notrecommended and could causeengine damage not covered by thevehicle warranty.
What to Do with Used Oil
Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean yourskin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or ragscontaining used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.
Used oil can be a threat to theenvironment. If you change yourown oil, be sure to drain all the oilfrom the filter before disposal. Neverdispose of oil by putting it in the
trash or pouring it on the ground,into sewers, or into streams orbodies of water. Recycle it by takingit to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer systemthat indicates when to change theengine oil and filter. This is basedon a combination of factors whichinclude engine revolutions, enginetemperature, and miles driven.Based on driving conditions, themileage at which an oil change isindicated can vary considerably. Forthe oil life system to work properly,the system must be reset every timethe oil is changed.
When the system has calculatedthat oil life has been diminished, itindicates that an oil change isnecessary. A CHANGE ENGINEOIL SOON message comes on. SeeEngine Oil Messages011 4.Change the oil as soon as possiblewithin the next 1 000 km (600 mi).It is possible that, if driving underthe best conditions, the oil life

system might indicate that an oilchange is not necessary for up to ayear. The engine oil and filter mustbe changed at least once a yearand, at this time, the system mustbe reset. Your dealer has trainedservice people who will perform thiswork and reset the system. It is alsoimportant to check the oil regularlyover the course of an oil draininterval and keep it at the properlevel.
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.
How to Reset the Engine Oil
Life System
Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. To reset thesystem:
1. Turn the ignition key to ON/RUN with the engine off.
2. Fully press and release theaccelerator pedal slowly threetimes within five seconds.
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.

Use this rotation pattern when
rotating the tires.
If the vehicle has a compact
spare tire, do not include it in the
tire rotation.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure0260andVehicle
Load Limits0171.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation0262.
Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque”underCapacities
and Specifications0309.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
ascraperorwirebrushlaterto
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
Dual Tire Rotation
When the vehicle is new,or whenever a wheel, wheel bolt,or wheel nut is replaced, check thewheel nut torque after160, 1 600, and 10 000 km (100,1,000, and 6,000 mi) of driving. Forproper wheel nut tighteninginformation, see“Removing the FlatTire and Installing the Spare Tire”underTire Changing0274.Alsosee“Wheel Nut Torque”underCapacities and Specifications0309.
The outer tire on a dual wheel setupgenerally wears faster than theinner tire. Tires last longer and wearmore evenly if they are rotated. SeeTire Inspection0265andTireRotation0265.AlsoseeMaintenance Schedule0297.
{Warning
If the vehicle is operated with a
tire that is underinflated, the tire
can overheat. An overheated tire
