Tire And Loading Information Placard
This placard tells you important
information about the:
1. Number of people that can be carried
in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the
front, rear, and spare tires.
Loading
The vehicle maximum load on the tire
must not exceed the load carrying
capacity of the tire on your vehicle. You
will not exceed the tire's load carrying
capacity if you adhere to the loading
conditions, tire size, and cold tire
inflation pressures specified on the Tire
and Loading Information placard in
“Vehicle Loading” in the “Starting And
Operating” section of this manual.Note:
Under a maximum loaded vehicle
condition, gross axle weight ratings
(GAWRs) for the front and rear axles
must not be exceeded. For further
information on GAWRs, vehicle loading,
and trailer towing, refer to “Vehicle
Loading” in the “Starting And Operating”
section of this manual.
To determine the maximum loading
conditions of your vehicle, locate the
statement “The combined weight of
occupants and cargo should never
exceed XXX kg or XXX lbs” on the Tire
and Loading Information placard. The
combined weight of occupants,
cargo/luggage and trailer tongue weight
(if applicable) should never exceed the
weight referenced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg or
XXX lbs.” on your vehicle's placard.
(2) Determine the combined weight
of the driver and passengers that will
be riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs. (4) The resulting figure equals the
available amount of cargo and
luggage load capacity. For example,
if “XXX” amount equals 1400 lbs. and
there will be five 150 lb passengers
in your vehicle, the amount of
available cargo and luggage load
capacity is 650 lbs. (1400-750
(5x150) = 650 lbs.)
(5) Determine the combined weight
of luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your vehicle.

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential
to the safe and satisfactory operation of
your vehicle. Four primary areas are
affected by improper tire pressure:
Safety and Vehicle Stability
Economy
Tread Wear
Ride Comfort
Safety
Warning!
Improperly inflated tires are dangerous
and can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result in
tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
Both under-inflation and over-inflation
affect the stability of the vehicle and can
produce a feeling of sluggish response or
over responsiveness in the steering.
Note:
Unequal tire pressures from side to
side may cause erratic and
unpredictable steering response.
Unequal tire pressure from side to
side may cause the vehicle to drift left or
right.
Fuel Economy
Underinflated tires will increase tire
rolling resistance resulting in higher fuel
consumption.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and
reduced tread life, resulting in the need
for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the driver's side B-Pillar or rear
edge of the driver's side door.
At least once a month:
Check and adjust tire pressure with a
good quality pocket-type pressure gauge.
Do not make a visual judgement when
determining proper inflation. Tires may
look properly inflated even when they are
under-inflated.
Inspect tires for signs of tire wear or
visible damage.
Caution!
After inspecting or adjusting the tire
pressure, always reinstall the valve stem
cap. This will prevent moisture and dirt from
entering the valve stem, which could
damage the valve stem.
Inflation pressures specified on the
placard are always “cold tire inflation
pressure”. Cold tire inflation pressure is
defined as the tire pressure after the
vehicle has not been driven for at least
three hours, or driven less than 1 mile
(1.6 km) after sitting for a minimum of
three hours. The cold tire inflation
pressure must not exceed the maximum
inflation pressure molded into the tire
sidewall.
216
SERVICING AND MAINTENANCE

Check tire pressures more often if
subject to a wide range of outdoor
temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately
1 psi (7 kPa) per 12°F (7°C) of air
temperature change. Keep this in mind
when checking tire pressure inside a
garage, especially in the Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 psi
(21 kPa), which equals 1 psi (7 kPa) for
every 12°F (7°C) for this outside
temperature condition.
Tire pressure may increase from 2 to
6 psi (13 to 40 kPa) during operation.
DO NOT reduce this normal pressure
build up or your tire pressure will be too
low.Tire Pressures For High Speed
Operation
The manufacturer advocates driving at
safe speeds and within posted speed
limits. Where speed limits or conditions
are such that the vehicle can be driven at
high speeds, maintaining correct tire
inflation pressure is very important.
Increased tire pressure and reduced
vehicle loading may be required for
high-speed vehicle operation. Refer to
your authorized tire dealer or original
equipment vehicle dealer for
recommended safe operating speeds,
loading and cold tire inflation pressures.
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision. Do not
drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
Recommended Cold Tire Inflation
Pressures
For vehicle speeds below 100 mph
(160 km/h), recommended cold tire
inflation pressures are listed on the Tire
And Loading Information Placard located
on driver’s side B-Pillar or the rear edge
of the driver's side door.
When driving at speeds 100 mph
(160 km/h) and above, increased tire
pressures and reduced vehicle loading
are required for high-speed vehicle
operation.
For driving speeds above 100 mph
(160 km/h) recommended cold tire
inflation pressures are listed below
under "High Speed Tire Inflation
Pressure". Vehicle loading condition
must not exceed 688 lbs. (312 kg)
(driver + three passengers + 88 lbs.
(40kg) luggage).
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to fail.
You could have a serious collision.

Radial Ply Tires
Warning!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability could
cause a collision. Always use radial ply tires
in sets of four. Never combine them with
other types of tires.
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).
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.
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.
See the tire pressure monitoring section
for more information.

SERVICING AND MAINTENANCE

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 continuously
without stopping.
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.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in
determining when your tires should be
replaced.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.
Refer to “Replacement Tires” in this
section for further information.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.
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.
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. Refer to the
paragraph on “Tread Wear Indicators” in
this section. Refer to the Tire and Loading
Information placard or the Vehicle

Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since 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.
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.
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 usefull 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.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified
by a label located on the limited use spare
wheel. This label contains the driving
limitations for this spare. This tire may
look like the original equipped tire on the
front or rear axle of your vehicle, but it is
not. Installation of this limited use spare
tire affects vehicle handling. 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!
Limited use spares are for emergency use
only. Installation of this limited use spare
tire affects vehicle handling. With this tire,
do not drive more than the speed listed on
the limited use spare wheel. Keep inflated to
the cold tire inflation pressures listed on
your Tire and Loading Information Placard
located on the driver’s side B-Pillar or the
rear edge of the driver’s side door. Replace
(or repair) the original equipment tire at the
first opportunity and reinstall it on your
vehicle. Failure to do so could result in loss of
vehicle control.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially
aluminum and chrome plated wheels,
should be cleaned regularly using mild
(neutral Ph) soap and water to maintain
their luster and to prevent corrosion.
Wash wheels with the same soap solution
recommended for the body of the vehicle
and remember to always wash when the
surfaces are not hot to the touch.
Your wheels are susceptible to
deterioration caused by salt, sodium
chloride, magnesium chloride, calcium
chloride, etc., and other road chemicals
used to melt ice or control dust on dirt
roads. Use a soft cloth or sponge and mild
soap to wipe away promptly. Do not use
harsh chemicals or a stiff brush. They can
damage the wheel’s protective coating
that helps keep them from corroding and
tarnishing.
Caution!
Avoid products or automatic car washes
that use acidic solutions or strong alkaline
additives or harsh brushes. Many
aftermarket wheel cleaners and automatic
car washes may damage the wheel's
protective finish. Such damage is not
covered by the New Vehicle Limited
Warranty. Only car wash soap is
recommended.
221

equipment or an authorized tire dealer
for recommended safe operating speeds,
loading and cold tire inflation pressures.
While studded tires improve
performance on ice, skid and traction
capability on wet or dry surfaces may be
poorer than that of non-studded tires.
Some states prohibit studded tires;
therefore, local laws should be checked
before using these tire types.
Tire Chains (Traction Devices)
Use of traction devices require sufficient
tire-to-body clearance. Follow these
recommendations to guard against
damage.
Note:
Traction device must be of proper
size for the tire, as recommended by the
traction device manufacturer
Use on Rear Tires Only
Due to limited clearance, the
following traction devices are
recommended:
For a 265/35R19 98V tire, use of a
zero-clearance snow traction device
recommended.
It is not possible to install traction
devices on 285/30R19 tires.
Caution!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device
clearance between tires and other
suspension components, it is important that
only traction devices in good condition are
used. Broken devices can cause serious
damage. Stop the vehicle immediately if
noise occurs that could indicate device
breakage. Remove the damaged parts of
the device before further use.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device
manufacturer’s instructions on the method
of installation, operating speed, and
conditions for use. Always use the
suggested operating speed of the device
manufacturer’s if it is less than 30 mph
(48 km/h).
Do not use traction devices on a compact
spare tire.
Tire Rotation Recommendations
Tire Rotations - Do Not Rotate Tires
Due to different size tires and wheels on
front and rear axles tire rotation is not
possible for:
2.9 L V6 Engine Equipped with 19”
tires and wheels
Caution!
Damage to the vehicle may occur if 19” front
and rear tires are rotated
In the case of irregular wear of the tires
identify the cause and correct it as soon
as possible, by contacting an authorized
dealer.
223

STORING THE VEHICLE
If the vehicle is left inactive for longer
than a month, the following precautions
should be observed:
Park the vehicle in an area that is
covered and dry, and well-ventilated if
possible. Slightly open the windows.
Check that the electric park brake is
not activated.
Carry out the procedure: “manual trunk
opening device” procedure described in
this paragraph.
Disconnect the negative battery
terminal and check the battery charge.
Repeat this check once every three
months during storage.
If the battery is not disconnected from
the electrical system, check its state of
charge every thirty days.
Clean and protect the painted parts
using protective wax.
Clean and protect the shiny metal
parts using special compounds available
commercially.
Sprinkle talcum powder on the
windshield wiper rubber blades, and lift
them off the glass.
Cover the vehicle with a fabric or
perforated plastic sheet, paying
particular care not to damage the painted
surface by dragging any dust that may
have accumulated on it. Do not use
compact plastic sheets, as they do not
allow humidity to evaporate from the
surface of the vehicle .
Inflate tires to +7.25 psi (+0.5 bar)
above the standard prescribed pressure
and check it periodically.
Do not drain the engine cooling
system.
Any time the vehicle is left inactive for
two weeks or more, operate the air
conditioning system with engine idling
for at least five minutes, setting external
air and with fan set to maximum speed.
This operation will ensure appropriate
lubrication for the system, thus
minimizing the possibility of damage to
the compressor when the system is
operated again.
Note: After cycling the ignition to STOP
and having closed the driver side door,
wait at least one minute before
disconnecting the electrical supply from
the battery. When reconnecting the
electrical supply to the battery, make
sure that the ignition is in the STOP
position and the driver side door is
closed. Manual Trunk Opening Device
Proceed as follows if the battery needs
to be disconnected:
1. From the trunk interior covering,
rotate the plug counterclockwise of the
lock and extract the cord connected to it.
