Trip A and Trip B
The trip displays show fuel used,
average fuel economy, and distance
traveled since the last trip reset.
Reset the trip data by pressing and
holding the SELECT button when
either Trip A or Trip B is displayed.
Oil Life
This displays the percentage of
remaining oil life. The lower
the percentage, the closer the
vehicle is to needing an oil change.

resetting of the Engine Oil Life
System. It cannot be reset
accurately until the next oil change.
To reset the Engine Oil Life System,
see
Engine Oil Life System on
page 10‑12. The system is reset
when 100% displays.
Tire Pressure
The display will show a vehicle with
the approximate pressures of all
four tires. Tire pressure is displayed
in either kilopascals (kPa) or in
pounds per square inch (psi).
If a low or high tire pressure is
detected, a message is displayed
advising to check the tire pressure
in the specified tire. See Tire
Pressure on page 10‑50 andTire
Messages on page 5‑55 for more
information. If the tire pressure display shows
dashes instead of a value, there
may be a problem with the vehicle.
See your dealer for service.

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑12.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.

Cooling System (Engine)
When it is safe to lift the hood:
A. Engine Coolant Surge Tank andPressure Cap
B. Engine Cooling Fans (Out of View)
{WARNING
The electric fans under the hood
can start up even when the
engine is not running and can
cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be up to
the cold fill line. If it is not, there
might be a leak at the radiator
hoses, heater hoses, radiator, water
pump, or somewhere else in the
cooling system.
{WARNING
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the vehicle if there is a
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.
If there seems to be no leak, with
the engine on, check to see if the
electric cooling fans are running.
If the engine is overheating, the fans
should be running. If it is not, the
vehicle needs service. Turn off the
vehicle.

Interior Care
To prevent dirt particle abrasions,
regularly clean the vehicle's interior.
Immediately remove any soils. Note
that newspapers or dark garments
that can transfer color to home
furnishings can also permanently
transfer color to the vehicle's
interior.
Use a soft bristle brush to remove
dust from knobs and crevices on the
instrument cluster. Using a mild
soap solution, immediately remove
hand lotions, sunscreen, and insect
repellant from all interior surfaces or
permanent damage may result.
Your dealer may have products for
cleaning the interior. Use cleaners
specifically designed for the
surfaces being cleaned to prevent
permanent damage. To prevent
overspray, apply all cleaners directly
to the cleaning cloth. Cleaners
should be removed quickly. Never
allow cleaners to remain on the
surface being cleaned for extended
periods of time.Cleaners may contain solvents that
can become concentrated in the
interior. Before using cleaners, read
and adhere to all safety instructions
on the label. While cleaning the
interior, maintain adequate
ventilation by opening the doors and
windows.
To prevent damage, do not clean
the interior using the following
cleaners or techniques:
.Never use a razor or any other
sharp object to remove a soil
from any interior surface.
.Never use a brush with stiff
bristles.
.Never rub any surface
aggressively or with excessive
pressure.
.Do not use laundry detergents or
dishwashing soaps with
degreasers. For liquid cleaners,
use approximately 20 drops per
3.78 L (1 gal) of water.
A concentrated soap solution will
leave a residue that creates
streaks and attracts dirt. Do not
use solutions that contain strong
or caustic soap.
.Do not heavily saturate the
upholstery when cleaning.
.Do not use solvents or cleaners
containing solvents.
