Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview
on page 6‑14for the
location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

Tire Terminology and Definitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the tire.
Air pressure is expressed in pounds per square
inch (psi) or kilopascal (kPa).
Accessory Weight
:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.
Aspect Ratio
:The relationship of a tire's height to
its width.
Belt
:A rubber coated layer of cords that is
located between the plies and the tread. Cords
may be made from steel or other reinforcing
materials.
Bead
:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire
:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread. Cold Tire Pressure
:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. See Inflation - Tire Pressure
on
page 6‑65
.
Curb Weight
:The weight of a motor vehicle with
standard and optional equipment including the
maximum capacity of fuel, oil, and coolant, but
without passengers and cargo.
DOT Markings
:A code molded into the sidewall
of a tire signifying that the tire is in compliance
with the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identification Number (TIN), an
alphanumeric designator which can also identify
the tire manufacturer, production plant, brand, and
date of production.
GVWR
:Gross Vehicle Weight Rating. See
Loading the Vehicle
on page 5‑19.
GAWR FRT
:Gross Axle Weight Rating for the
front axle. See Loading the Vehicle
on page 5‑19.

Do not clean the vehicle using:
.A knife or any other sharp object to remove a soil
from any interior surface.
.A stiff brush. It can cause damage to the vehicle's
interior surfaces.
.Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
.Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide. Use only
mild, neutral-pH soaps.
.Too much cleaner that saturates the upholstery.
.Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle's interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be
used on floor carpet and carpeted floor mats. For any
soil, always try to remove it first with plain water or club
soda. Before cleaning, gently remove as much of the
soil as possible using one of the following techniques:
.For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the paper
towel until no more can be removed.
.For solid dry soils: remove as much as possible
and then vacuum.
To clean: 1. Saturate a lint-free, clean white cloth with water or club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
4. Continue to gently rub the soiled area until the cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild soap solution and repeat the cleaning process that
was used with plain water.
6-102

Rinse the vehicle well, before washing and after to
remove all cleaning agents completely. If they are
allowed to dry on the surface, they could stain.
Dry the finish with a soft, clean chamois or an all-cotton
towel to avoid surface scratches and water spotting.
High pressure car washes may cause water to enter the
vehicle. Avoid using high pressure washes closer than
12 inches (30 cm) to the surface of the vehicle. Use of
power washers exceeding 1,200 psi (8 274 kPa) can
result in damage or removal of paint and decals.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions underWashing Your Vehicle
on
page 6‑104.
Finish Care
Occasional waxing or mild polishing of the vehicle by
hand may be necessary to remove residue from the
paint finish. Approved cleaning products can be
obtained from your dealer. If the vehicle has a basecoat/clearcoat paint finish, the
clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat paint
finish.
Notice:
Machine compounding or aggressive
polishing on a basecoat/clearcoat paint finish may
damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat
paint finish on the vehicle.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage the vehicle's finish if they remain on painted
surfaces. Wash the vehicle as soon as possible.
If necessary, use non-abrasive cleaners that are
marked safe for painted surfaces to remove foreign
matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a period
of years. To help keep the paint finish looking new, keep
the vehicle garaged or covered whenever possible.

Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). SeeTire Inspection
and Rotation on page 6‑71.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑17. An Emission Control Service.
When the Change Engine Oil Soon message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset. Your
dealer has trained service technicians who will perform
this work and reset the system. If the engine oil life
system is reset accidentally, service the vehicle within
5 000 km/3,000 miles since the last service. Reset the
oil life system whenever the oil is changed. See Engine
Oil Life System on page 6‑20. When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
The services described for Maintenance
Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be
performed when:
.Maintenance Iwas performed the last time the
engine oil was changed.
.It has been 10 months or more since the Change
Engine Oil Soon message has displayed or since
the last service.
