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 thetrash 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 which
include 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 5.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 lifesystem 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.

leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.
Engine Coolant
The cooling system in the vehicle isfilled with DEX-COOL®enginecoolant. This coolant is designed toremain in the vehicle for 5 years or240 000 km (150,000 mi), whicheveroccurs first.
The following explains the coolingsystem and how to check and addcoolant when it is low. If there is aproblem with engine overheating,seeEngine Overheating0284.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the
