Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine
oil and filter. The oil life system
should be reset to 100% only
following an oil change. Resetting the Oil Life System
1. Turn the ignition to ON/RUN, with the engine off.
2. Fully press and release the accelerator pedal slowly three
times within five seconds.
3. Turn the key to LOCK/OFF.
See Engine Oil Life System 0221.

When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
SeeEngine Oil Messages 0114.
You should change the oil as soon
as possible. See Engine Oil0219.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Maintenance Schedule 0298.
Remember, you must reset the OIL
LIFE yourself after each oil change.
It will not reset itself. Also, be
careful not to reset the OIL LIFE
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
engine oil life system, see Engine
Oil Life System 0221.

This message displays when the
engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down. SeeEngine
Coolant Temperature Gauge 098.
ENGINE OVERHEATED STOP
ENGINE
This message displays and a chime
sounds if the engine cooling system
reaches unsafe temperatures for
operation. Stop and turn off the
vehicle as soon as it is safe to do so
to avoid severe damage. This
message clears when the engine
has cooled to a safe operating
temperature.
Engine Oil Messages
CHANGE ENGINE OIL SOON
This message displays when the
engine oil needs to be changed.
When you change the engine oil, be
sure to reset the CHANGE ENGINE
OIL SOON message. See Engine
Oil Life System 0221 for
information on how to reset the
message.
See Engine Oil 0219 and
Maintenance Schedule 0298.
ENGINE OIL LOW ADD OIL
If the vehicle has an oil level sensor,
this message displays if the oil level
in the vehicle is low. Check the oil
level and correct it as necessary.
You may need to let the vehicle cool
or warm up and cycle the ignition to
be sure this message clears. See
Engine Oil 0219.
OIL PRESSURE LOW STOP
ENGINE
This message displays if low oil
pressure levels occur. Stop the
vehicle as soon as safely possible
and do not operate it until the cause of the low oil pressure has been
corrected. Check the oil as soon as
possible and have the vehicle
serviced by your dealer. See

Reduced engine power can affect
the vehicle's ability to accelerate.
If this message is on, but there is no
reduction in performance, proceed
to your destination. The
performance may be reduced the
next time the vehicle is driven. The
vehicle may be driven at a reduced
speed while this message is on, but
acceleration and speed may be
reduced. Anytime this message

system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:1. Turn the ignition key to ON/ RUN with the engine off. 2. Fully press and release the
accelerator pedal slowly three
times within five seconds.
3. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to check
the transmission fluid level. The only
reason for fluid loss is a
transmission leak or overheated
transmission. If a small leak is
suspected, use the following
procedures to check the fluid level.
However, if there is a large leak, it
may be necessary to have the
vehicle towed to a dealer and have
it repaired before driving the vehicle
further. Change the fluid and filter at the
intervals listed in
Maintenance
Schedule 0298, and be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants 0306.
How to Check Automatic
Transmission Fluid
Because this operation can be
difficult, it is recommended to have
this check done at your dealer,
which can monitor the transmission
temperature. The transmission fluid
level increases with temperature. To
obtain a highly accurate fluid level
check, the transmission temperature
must be measured.
If it is decided to check the fluid
level, be sure to follow all the
instructions here, or a false reading
on the dipstick may occur.
Caution
Too much or too little fluid can
damage the transmission. Too
much can mean that some of the

266 Vehicle Care
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.
SeeTire Pressure 0260 and
Vehicle Load Limits 0171.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation 0262. Check that all wheel nuts are
properly tightened. See
“Wheel
Nut Torque” underCapacities
and Specifications 0310.
{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
a scraper or wire brush later to
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 the
wheel nut torque after
160, 1 600, and 10 000 km (100,
1,000, and 6,000 mi) of driving. For
proper wheel nut tightening
information, see “Removing the Flat
Tire and Installing the Spare Tire”
under Tire Changing 0274. Also
see “Wheel Nut Torque” under
Capacities and Specifications 0310.
The outer tire on a dual wheel setup
generally wears faster than the
inner tire. Tires last longer and wear
more evenly if they are rotated.
See Tire Inspection 0265 andTire
Rotation 0265. Also see
Maintenance Schedule 0298.
{Warning
If the vehicle is operated with a
tire that is underinflated, the tire
can overheat. An overheated tire
can lose air suddenly or catch

be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the
last service. Reset the oil life
system when the oil is changed.
