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

SERVICING AND MAINTENANCE

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.

Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and

there will be five 68 kg passengers in your vehicle,

the amount of available cargo and luggage load

capacity is 295 kg (635-340 (5x68) = 295 kg) as

shown in step 4.

NOTE:



If your vehicle will be towing a trailer, load from

your trailer will be transferred to your vehicle.

The following table shows examples on how to

calculate total load, cargo/luggage, and towing

capacities of your vehicle with varying seating

configurations and number and size of occu

-

pants. This table is for illustration purposes only

and may not be accurate for the seating and

load carry capacity of your vehicle.



For the following example, the combined weight

of occupants and cargo should never exceed

865 lb (392 kg).

WARNING!

Overloading of your tires is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the

recommended load capacity for your vehicle. Never overload them.

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



Fuel Economy



Tread Wear



Ride Comfort and Vehicle Stability

Safety

Both underinflation and overinflation 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. Overinflation 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 judgment 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.

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.

WARNING!

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.

SERVICING AND MAINTENANCE

277

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.
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

an authorized tire dealer or original equipment

vehicle dealer for recommended safe operating

speeds, loading and cold tire inflation pressures.

Radial Ply 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). 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

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).

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.

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.

page 185.

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.
For further information

Ú

page 231.

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.
For further information

Ú

page 279.

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 pres

-

sures 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.

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.
