Extended Parking
It is best not to park with the
vehicle running. If the vehicle is
left running, be sure it will not
move and there is adequate
ventilation.
See Shifting Into Park0258
and Engine Exhaust 0260.
If the vehicle is left parked and
running with the remote key
outside the vehicle, it will
continue to run for up to
15 minutes. If the vehicle is left parked and
running with the remote key
inside the vehicle, it will
continue to run for up to
30 minutes.
The vehicle could turn off
sooner if it is parked on a hill,
due to lack of available fuel.
The timer will reset if the
vehicle is taken out of P (Park)
while it is running.
Engine Exhaust
{
Warning
Engine exhaust contains
carbon monoxide (CO),
which cannot be seen or
smelled. Exposure to CO can
cause unconsciousness and
even death.
Exhaust may enter the
vehicle if:
.The vehicle idles in areas
with poor ventilation
(parking garages, tunnels, (Continued)

deep snow that may block
underbody airflow or tail
pipes).
.The exhaust smells or
sounds strange or
different.
.The exhaust system leaks
due to corrosion or
damage.
.The vehicle exhaust
system has been modified,
damaged, or improperly
repaired.
.There are holes or
openings in the vehicle
body from damage or
aftermarket modifications
that are not completely
sealed.
If unusual fumes are
detected or if it is suspected
that exhaust is coming into
the vehicle:

Engine Oil Life
System
When to Change
Engine Oil
This vehicle has a computer
system that indicates when to
change the engine oil and
filter. This is based on a
combination of factors which
include engine revolutions,
engine temperature, and miles
driven. Based on driving
conditions, the mileage at
which an oil change is
indicated can vary
considerably. For the oil life
system to work properly, the
system must be reset every
time the oil is changed.
When the system has
calculated that oil life has been
diminished, it indicates that an
oil change is necessary.
A CHANGE ENGINE OIL
SOON message comes on.
Change the oil as soon as
possible within the next
1 000 km (600 mi). It ispossible that, if driving under
the best conditions, the oil life
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. Using the DIC controls on the right side of the
steering wheel, display
REMAINING OIL LIFE on
the DIC. See Driver
Information Center (DIC)
0139. When remaining oil
life is low, the CHANGE
ENGINE OIL SOON
message will appear on the
display.
2. Press SEL on the DIC controls and hold SEL
down for a few seconds to
clear the CHANGE ENGINE
OIL SOON message and
reset the oil life at 100%.
Be careful not to reset the
oil life display accidentally
at any time other than
after the oil is changed.

16406251) - 2023 - CRC - 3/28/22
Vehicle Care 349
It cannot be reset
accurately until the next oil
change.
The oil life system can also be
reset as follows: 1. Display REMAINING OIL LIFE on the DIC. See Driver
Information Center (DIC)
0139.
2. Fully press and release the accelerator pedal three
times within five seconds.
If the CHANGE ENGINE
OIL SOON message is not
on, the system is reset.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off.
If the CHANGE ENGINE OIL
SOON message comes back
on when the vehicle is started,
the engine oil life system has
not been reset. Repeat the
procedure.Automatic
Transmission Fluid
A transmission fluid leak is the
only reason for fluid loss. If a
leak occurs, take the vehicle to
your dealer and have it
repaired as soon as possible.
Caution
Use of the incorrect
automatic transmission fluid
may damage the vehicle, and
the damage may not be
covered by the vehicle
warranty. Always use the
correct automatic
transmission fluid. See
Recommended Fluids and
Lubricants 0433.
See your dealer to have the
fluid and filter changed at the
intervals listed in the
Maintenance Schedule 0429.
Engine Air Filter Life
System
If equipped, this feature
provides the engine air filter’s
remaining life and best timing
for a change. The timing to
change an engine air filter
depends on driving and
environmental conditions.
When to Change the
Engine Air Filter
When the Driver Information
Center (DIC) displays a
message to replace the engine
air filter at the next oil change,
follow this timing.
When the DIC displays a
message to replace the engine
air filter soon, replace the
engine air filter at the earliest
convenience.
The system must be reset
after the engine air filter is
changed.
If the DIC displays a message
to check the engine air filter
system, see your dealer.

Bulb Replacement
For the proper type of
replacement bulbs, or any bulb
changing procedure not listed
in this section, contact your
dealer.
Caution
Do not replace incandescent
bulbs with aftermarket LED
replacement bulbs. This can
cause damage to the vehicle
electrical system.
LED Lighting
This vehicle has several LED
lamps. For replacement of any
LED lighting assembly, contact
your dealer.
Electrical System
Electrical System
Overload
The vehicle has fuses and
circuit breakers to protect
against an electrical system
overload.
When the current electrical
load is too heavy, the circuit
breaker opens and closes,
protecting the circuit until the
current load returns to normal
or the problem is fixed. This
greatly reduces the chance of
circuit overload and fire
caused by electrical problems.
Fuses and circuit breakers
protect power devices in the
vehicle.If there is a problem on the
road and a fuse needs to be
replaced, the same amperage
fuse can be borrowed. Choose
some feature of the vehicle
that is not needed to use and
replace it as soon as possible.
To check a fuse, look at the
band inside the fuse. If the
band is broken or melted,
replace the fuse. Be sure to
replace a bad fuse with a fuse
of the identical size and rating.

Tire Rotation
Tires should be rotated
according to the interval
specified in the
Maintenance Schedule. See
Maintenance Schedule
0429.
Tires are rotated to
achieve a more uniform
wear for all tires. The first
rotation is the most
important. Anytime unusual wear is
noticed, rotate the tires as
soon as possible, check for
proper tire inflation
pressure, and check for
damaged tires or wheels.
If the unusual wear
continues after the
rotation, check the wheel
alignment. See When It Is
Time for New Tires
0394
and Wheel Replacement
0 399.
Use this rotation pattern
when rotating the tires. Do not include the compact
spare tire 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 Pressure
0384
and Vehicle Load Limits
0 247.
Reset the Tire Pressure
Monitor System. See Tire
Pressure Monitor
Operation 0388.
Check that all wheel nuts
are properly tightened. See
