Tire Repair
If your tire becomes damaged, it may be repaired
if it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of your
tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an inch
(6 mm).
Consult an authorized tire dealer for tire repairs
and additional information.

Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical
size and service description (Load Index and
Speed Symbol). Replace the tire pressure sensor
as well as it is not designed to be reused.

Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a rapid loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A
Run Flat mode occurs when the tire inflation pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable. When a run flat tire is changed after
driving with underinflated tire condition, please
replace the TPMS sensor as it is not designed to
be reused when driven under run flat mode 14 psi
(96 kPa) condition.

NOTE:
TPMS Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded at
full capacity or to tow a trailer while a tire is in the
run flat mode.

Tire Spinning
When stuck in mud, sand, snow, or ice conditions,
do not spin your vehicle's wheels above 30 mph
(48 km/h) or for longer than 30 seconds contin-
uously without stopping.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining when
your tires should be replaced.
Tire Tread These indicators are molded into the bottom of
the tread grooves. They will appear as bands
when the tread depth becomes a 1/16 of an inch
(1.6 mm). When the tread is worn to the tread
wear indicators, the tire should be replaced.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns to
develop across the tire tread. These abnormal
wear patterns will reduce tread life, resulting in
the need for earlier tire replacement.
Distance driven.
Performance tires, tires with a speed rating of
V or higher, and Summer tires typically have a
reduced tread life. Rotation of these tires per
the vehicle scheduled maintenance is highly
recommended.

NOTE:
Wheel valve stem must be replaced as well when
installing new tires due to wear and tear in
existing tires. Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed

Ú
page 225. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size
designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the
original equipment tire sidewall.
See the Tire Sizing Chart example for more
information relating to the Load Index and Speed
Symbol of a tire

Ú
page 216.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you
ever replace a wheel, make sure that the wheel’s
specifications match those of the original wheels.
It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling,
and ride of your vehicle.
WARNING!

Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.

1 — Worn Tire
2 — New Tire
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can result
in sudden tire failure. You could lose control
and have a collision resulting in serious injury
or death.

SPARE TIRES — IF EQUIPPED

NOTE:
For vehicles equipped with Tire Service Kit
instead of a spare tire
Ú
page 181.
Spare Tire Matching Original Equipped
Tire And Wheel — If Equipped
Your vehicle may be equipped with a spare tire
and wheel equivalent in look and function to the
original equipment tire and wheel found on the
front or rear axle of your vehicle. This spare tire
may be used in the tire rotation for your vehicle. If
your vehicle has this option, refer to an
authorized tire dealer for the recommended tire
rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a compact spare by looking at the
spare tire description on the Tire and Loading
Information Placard located on the driver’s side
door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare TireSince this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first
opportunity.
Do not install a wheel cover or attempt to mount
a conventional tire on the compact spare wheel,
since the wheel is designed specifically for the
compact spare tire. Do not install more than one
compact spare tire and wheel on the vehicle at
any given time.
Full Size Spare — If Equipped
The full size spare is for temporary emergency
use only. This tire may look like the originally
equipped tire on the front or rear axle of your
vehicle, but it is not. This spare tire may have
limited tread life. When the tread is worn to the
tread wear indicators, the temporary use full size
spare tire needs to be replaced. Since it is not the
same as your original equipment tire, replace (or
repair) the original equipment tire and reinstall
on the vehicle at the first opportunity.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire
overloading and failure. You could lose
control and have a collision.
Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle
control.
CAUTION!
Replacing original tires with tires of a different
size may result in false speedometer and
odometer readings.
CAUTION!
Because of the reduced ground clearance, do
not take your vehicle through an automatic car
wash with a compact or limited use temporary
spare installed. Damage to the vehicle may
result.
WARNING!
Compact and collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have limited
tread life. When the tread is worn to the tread
wear indicators, the temporary use spare tire
needs to be replaced. Be sure to follow the
warnings, which apply to your spare. Failure to
do so could result in spare tire failure and loss
of vehicle control.

TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles
operate at different loads and perform different
steering, driving, and braking functions. For these
reasons, they wear at unequal rates. These
effects can be reduced by timely rotation of tires.
Rotation will increase tread life, maintain traction
levels and contribute to a smooth, quiet ride.
To resolve this problem, tires should be rotated at
each service interval (approximately every
10,000 miles [16,000 km]). More frequent
rotation is permissible if desired. The reasons for
any rapid or unusual wear should be corrected
prior to rotation being performed.
Tire Rotations Not Recommended — If Equipped
Due to different size tires and wheels on front and
rear axles, tire rotation is not possible for:
2.0L Engine equipped with a different front and
rear tire size.
Tire rotation contributes to the preservation of the
grip and traction performance on wet, muddy or
snowy roads, guaranteeing optimal drivability of
the vehicle.
In the case of irregular wear of the tires identify
the cause and correct it as soon as possible, by
contacting an authorized dealer.
The rotational direction of the tire must be taken
into consideration when rotating the tires. The
recommended rotation pattern for directional
tires is shown in the following diagram.Tire Rotation
It is recommended to avoid situations with a large
difference in wear between the front and rear
tires and to strictly use Winter tires of the sizes
given on the tire placard.
The AWD system and the original tires are
developed together to ensure the vehicle’s best
performance. When changing the tires, it is
recommended to us the same “AR” marked tires,
to maintain the same level of performance and
component life.
DEPARTMENT OF
TRANSPORTATION
UNIFORM TIRE QUALITY
GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the tire's manufacturer in each
category is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must
conform to Federal safety requirements
in addition to these grades.
TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half times
as well on the government course as a
tire graded 100. The relative
performance of tires depends upon the
actual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving habits,
service practices, and differences in
road characteristics and climate.
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
CAUTION!
Damage to the vehicle may occur if different
front and rear tire sizes are rotated

BODYWORK
PROTECTION AGAINST ATMOSPHERIC
A
GENTS
The vehicle is equipped with the best available
technological solutions to protect the bodywork
against corrosion.
These include:
Painting products and systems which give the
vehicle resistance to corrosion and abrasion.
Use of galvanized (or pre-treated) steel sheets,
with high resistance to corrosion.
Spraying of plastic parts, with a protective
function in the more exposed points: under
door, inner wing, edges, etc.
Use of “open” boxed sections to prevent
condensation and pockets of moisture which
could favor the formation of rust inside.
Use of special films to protect against abrasion
in exposed areas (e.g. rear wing, doors, etc.).
CORROSION WARRANTY
Your vehicle is covered by Corrosion Warranty
against perforation due to rust of any original
element of the structure or bodywork. For the
general terms of this warranty, refer to the
Warranty Booklet.
PRESERVING THE BODYWORK
Paint
Touch up abrasions and scratches immediately to
prevent the formation of rust.
Maintenance of paintwork consists of washing
the vehicle: the frequency depends on the conditions and environment where the vehicle is
used. For example, it is advisable to wash the
vehicle more often in areas with high levels of
atmospheric pollution or salted roads.
Some parts of the vehicle may be covered with a
matte paint which, in order to be maintained
intact, requires special care.
To correctly wash the vehicle, follow these
instructions:
If high pressure jets or cleaners are used to
wash the vehicle, keep a distance of at least
15 inches (40 cm) from the bodywork to avoid
damage or alteration. Build up of water could
cause damage to the vehicle in the long term.
To make it easier to remove any dirt deposits in
the area where the blades are normally located
it is recommended to position the windshield
wipers vertically (service position)

Ú
page 201.
Wash the bodywork using a low pressure jet of
water if possible.
Wipe a sponge with a slightly soapy solution
over the bodywork, frequently rinsing the
sponge.
Rinse well with water and dry with a leather
chamois.
Dry the less visible parts (e.g. door frames, hood,
headlight frames, etc.) with special care, as water
may stagnate more easily in these areas. Do not
wash the vehicle after it has been left in the sun
or with the hood hot: this may alter the shine of
the paintwork.

NOTE:
Avoid parking under trees; the resin dropped by
trees makes the paintwork go opaque and
increases the possibility of corrosion. Exterior plastic parts must be cleaned in the
same way as the rest of the vehicle.

If washing the vehicle in a service that moves the
vehicle, for vehicles with automatic transmissions,
proceed with the following directions:

Ensure that the vehicle is on a flat surface.
Disable the automatic engagement of the
parking brake
Ú
page 84.
With the vehicle stationary, the gear in
NEUTRAL (N) and the brake pedal pressed,
push the START button.

NOTE:
The vehicle will remain in NEUTRAL (N) for
15 minutes before PARK (P) will be engaged auto
-
matically.
Windows
Use specific detergents and clean cloths to
prevent scratching or altering the transparency.
Front Headlights
Use a soft cloth soaked in water and detergent for
washing vehicles.

NOTE:

Never use aromatic substances (e.g. gasoline)
or ketones (e.g. acetone) for cleaning the
plastic lenses of the headlights.
When cleaning with a pressure washer, keep
the pressure washer at least eight inches
(20 cm) away from the headlights.
CAUTION!
Wipe the rear window inside gently with a cloth
following the direction of the filaments to avoid
damaging the heating device.

FUEL REQUIREMENTS

This engine is designed to meet all
emission regulations, and provide
satisfactory fuel economy and
performance when using high-quality
unleaded regular gasoline having a posted octane
number of 87 as specified by the (R+M)/2 method.
For optimal performance the use of 91 or higher
octane premium gasoline is recommended in these
engines.

While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see an authorized dealer
immediately. Use of gasoline with a lower than
recommended octane number can cause engine
failure and may void or not be covered by the New
Vehicle Limited Warranty. Poor quality gasoline can cause problems such as
hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the
vehicle.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as
“reformulated gasoline”. Reformulated gasoline
contains oxygenates and are specifically blended
to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is
recommended. Properly blended reformulated
gasoline will provide improved performance and
durability of engine and fuel system components.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.

CAUTION!
DO NOT use E-85, gasoline containing
methanol, or gasoline containing more than
15% ethanol (E-15). Use of these blends may
result in starting and drivability problems,
damage critical fuel system components,
cause emissions to exceed the applicable
standard, and/or cause the Malfunction
Indicator Light to illuminate. Please observe
pump labels as they should clearly
communicate if a fuel contains greater than
15% ethanol (E-15).

(Continued)
Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the respon
-
sibility of the manufacturer and may void or not
be covered under New Vehicle Limited Warranty.
CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the engine,
emissions, and fuel system components.
Problems that result from running CNG or LP are
not the responsibility of the manufacturer and
may void or not be covered under the New
Vehicle Limited Warranty.
MMT IN GASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic
additive that is blended into some gasoline to
increase octane. Gasoline blended with MMT
provides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark
plug life and reduces emissions system
performance in some vehicles. The manufacturer
recommends that gasoline without MMT be used
in your vehicle. The MMT content of gasoline may
not be indicated on the gasoline pump; therefore,
you should ask your gasoline retailer whether the
gasoline contains MMT. MMT is prohibited in
Federal and California reformulated gasoline.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in minimizing
engine and fuel system deposits. When
available, the usage of TOP TIER Detergent
Gasoline is recommended. Visit

www.toptiergas.com
for a list of TOP TIER
Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials
intended for gum and varnish removal may
contain active solvents or similar ingredients.
These can harm fuel system gasket and
diaphragm materials.
FUEL SYSTEM CAUTIONS
NOTE:
Intentional tampering with the emissions control
system can result in civil penalties being
assessed against you.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage the
emissions control system.
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the catalytic
converter to overheat. If you notice a
pungent burning odor or some light smoke,
your engine may be out of tune or malfunc-
tioning and may require immediate service.
Contact an authorized dealer for service
assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle performance
problems resulting from the use of such fuels
or additives is not the responsibility of the
manufacturer and may void or not be
covered under the New Vehicle Limited
Warranty.
CAUTION!
