.Spray nozzle with a
40 degree wide angle spray
pattern or wider must
be used.
.Nozzle must be kept at least
30 cm (1 ft) away from all
surfaces.
Finish Care
Application of aftermarket
clearcoat sealant/wax
materials is not recommended.
If painted surfaces are
damaged, see your dealer to
have the damage assessed
and repaired. 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.Occasional hand waxing or
mild polishing should be done
to remove residue from the
paint finish. See your dealer
for approved cleaning
products.
Do not apply waxes or
polishes to uncoated plastic,
vinyl, rubber, decals, simulated
wood, or flat paint as damage
can occur.
Caution
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.
To keep the paint finish
looking new, keep the vehicle
garaged or covered whenever
possible. Protecting Exterior Bright
Metal Moldings
Caution
Failure to clean and protect
the bright metal moldings
can result in a hazy white
finish or pitting. This damage
would not be covered by the
vehicle warranty.
The bright metal moldings on
the vehicle are aluminum,
chrome, or stainless steel. To
prevent damage always follow
these cleaning instructions:
.Be sure the molding is cool
to the touch before applying
any cleaning solution.
.Use only approved cleaning
solutions for aluminum,
chrome, or stainless steel.
Some cleaners are highly
acidic or contain alkaline
substances and can damage
the moldings.
.Always dilute a concentrated
cleaner according to the
manufacturer’s instructions.

replacement parts will provide
the corrosion protection while
maintaining the vehicle
warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up
materials available from your
dealer to avoid corrosion.
Larger areas of finish damage
can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall
upon and attack painted
vehicle surfaces causing
blotchy, ring-shaped
discolorations, and small,
irregular dark spots etched
into the paint surface. See
“Finish Care”previously in this
section.
Interior Care
To prevent dirt particle
abrasions, regularly clean the
vehicle's interior. Before using cleaners, read and follow all
safety instructions on the
label. While cleaning the
interior, open the doors and
windows to get proper
ventilation. Newspapers or
dark garments can transfer
color to the vehicle’s interior.
Caution
Immediately remove
cleaners, hand lotions,
sunscreen, and insect
repellent from all interior
surfaces or permanent
damage may result.
Caution
Use cleaners specifically
designed for the surfaces
being cleaned to prevent
permanent damage to the
vehicle. Apply all cleaners
directly to a cleaning cloth.
Do not spray cleaners on
any switches or controls.
When using liquid soap
cleaners, follow the directions
on the specific cleaner or soap
solution for dilution
instructions.
Caution
To prevent damage:
.Never use a razor or any
other sharp object to
remove soil from any
interior surface
.Never use a brush with
stiff bristles.
.Never rub any surface
aggressively or with too
much pressure.
.Do not get any exposed
electrical components wet.
.Do not use laundry
detergents or dishwashing
soaps with degreasers. Do
not use solutions that
contain strong or
caustic soap.

Caution (Continued)
.Do not heavily saturate
the upholstery when
cleaning.
.Do not use solvents or
cleaners containing
solvents.
.Do not use disinfecting
wipes that are scented or
contain bleach. Do not use
wipes or cleaners that
show a color transfer to
the wipe or change the
appearance of the interior
surface when used.
.Do not use scented or
gel-type hand sanitizers.
If hand sanitizer comes in
contact with interior
surfaces of the vehicle,
blot immediately and clean
with a soft cloth
dampened with a mild
soap and water solution.
Interior Glass
To clean, use a microfiber
cloth fabric dampened with
water. Wipe droplets left
behind with a clean dry cloth.
If necessary, use a commercial
glass cleaner after cleaning
with plain water.
Caution
To prevent scratching, never
use abrasive cleaners on
automotive glass. Abrasive
cleaners or aggressive
cleaning may damage the
rear window defogger.
Cleaning the windshield with
water during the first three to
six months of ownership will
reduce tendency to fog.
Speaker Covers
Vacuum around a speaker
cover gently, so that the
speaker will not be damaged.
Clean spots with water and
mild soap.
Coated Moldings
Coated moldings should be
cleaned.
.When lightly soiled, wipe
with a sponge or soft,
lint-free cloth dampened
with water.
.When heavily soiled, use
warm soapy water.
Vinyl/Rubber
If equipped with vinyl floor and
rubber floor mats, use a soft
cloth and/or brush dampened
with water to remove dust and
loose dirt. For more thorough
cleaning, use a mild soap and
water solution.
{Warning
Do not use cleaners that
contain silicone, wax-based
products, or cleaners that
increase gloss on vinyl/
rubber floor and mats.
These cleaners can
permanently change the (Continued)

appearance and feel of the
vinyl/rubber and can make
the floor slippery. Your foot
could slip while operating
the vehicle, and you could
lose control, resulting in a
crash. You or others could
be injured.
Fabric/Carpet/Suede
Start by vacuuming the
surface using a soft brush
attachment. If a rotating
vacuum brush attachment is
being used, only use it on the
floor carpet. Before cleaning,
gently remove as much of the
soil as possible:
.Gently blot liquids with a
paper towel. Continue
blotting until no more soil
can be removed.
.For solid soils, remove as
much as possible prior to
vacuuming.To clean:
1. Saturate a clean, lint-free colorfast cloth with water.
Microfiber cloth is
recommended to prevent
lint transfer to the fabric
or carpet.
2. Remove excess moisture by gently wringing until
water does not drip from
the cleaning cloth.
3. Start on the outside edge of the soil and gently rub
toward the center. Fold
the cleaning cloth to a
clean area frequently to
prevent forcing the soil
into the fabric.
4. Continue gently rubbing the soiled area until there
is no longer any color
transfer from the soil to
the cleaning cloth.
5. If the soil is not completely removed, use a mild soap
solution followed only by
plain water. If the soil is not completely
removed, it may be necessary
to use a commercial
upholstery cleaner or spot
lifter. Test a small hidden area
for colorfastness before using
a commercial upholstery
cleaner or spot lifter. If ring
formation occurs, clean the
entire fabric or carpet.
After cleaning, use a paper
towel to blot excess moisture.
Cleaning High Gloss
Surfaces and Vehicle
Information and Radio
Displays
Use a microfiber cloth on high
gloss surfaces or vehicle
displays. First, use a soft
bristle brush to remove dirt
that can scratch the surface.
Then gently clean by rubbing
with a microfiber cloth. Never
use window cleaners or
solvents. Periodically hand
wash the microfiber cloth
separately, using mild soap. Do

Tire Rotation and
Required Services Every
12 000 km (7,500 mi)
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.

.Check engine oil level and oil
life percentage. If needed,
change engine oil and filter,
and reset oil life system. Or
when the CHANGE ENGINE
OIL SOON message displays,
have the engine oil and filter
changed within the next
1 000 km (600 mi). If driven
under the best conditions,
the engine oil life system
may not indicate the need
for vehicle service for up to
a year. The engine oil and
filter must be changed at
least once a year and the oil
life system must 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. See Engine Oil Life
System
0373.
.When the REPLACE AT
NEXT OIL CHANGE
message displays, the engine
air filter should be replaced
at the next engine oil
change. When the REPLACE

message displays, the engine
air filter should be replaced
at the earliest convenience.
Reset the engine air filter life
system after the engine air
filter is replaced. See Engine
Air Filter Life System 0374.
