Your vehicle is equipped with the Tire and
Loading Information placard located on
the driver’s door B‑pillar (Y page 133).
The tire inflation pressure should be
checked regularly. Only adjust the tire
inflation pressure on cold tires. The tires can be considered cold if the vehicle has
been parked for at least 3 hours or driven
less than 1 mile (1.6 km). Depending on the
ambient temperature, the driving speed
and the tire load, the tire temperature
changes. When the tire temperature
changes by 18¦ (10¥), the tire inflation
pressure will change by approximately
10 kpa (0.1 bar, 1.5 psi). Keep this in mind
when checking tire inflation pressure on
warm tires and adjust the tire pressure
only if the tire inflation pressure is too
low for the current operating conditions.
If you check the tire inflation pressure
when the tires are warm, the reading will be
higher than the cold reading. This is nor-
mal. Do not let air out to match the speci-
fied cold tire inflation pressure. Other-
wise, the tire will be underinflated.
Follow recommended cold tire inflation
pressures listed on Tire and Loading
Information placard on the driver’s door
B‑pillar.
Keeping the tires properly inflated pro-
vides the best handling, tread life and rid-
ing comfort.
In addition to the Tire and Loading Infor-
mation placard on the driver’s door B‑pil- lar, also consult the tire inflation pres-
sure label (if available) on the inside of
the filler flap for any additional informa-
tion pertaining to special driving situa-
tions. For more information, see “Impor-
tant notes on tire inflation pressure”
(Y page 129).
i Data shown on Tire and Loading Infor-
mation placard example are for illus-
tration purposes only. Tire data are spe- cific to each vehicle and may vary from
data shown in the following illustration. Refer to Tire and Loading Information
placard on vehicle for actual data spe-
cific to your vehicle.
The Tire and Loading Information placard
lists the recommended cold tire inflation
pressures :for maximum loaded vehicle
weight. The tire inflation pressures listed apply to the tires installed as original
equipment.
Important notes on tire inflation pres-
sure G
WARNING
If the tire inflation pressure drops repeat- edly, check the tires for punctures from
foreign objects and/or whether air is leak-
ing from the valves or from around the rim.
Tire temperature and tire inflation pres-
sure are also increased while driving,
depending on the driving speed and the
tire load.

WARNING
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption of the vehicle, and are more

deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the
tires can overheat them, possibly causing a
blowout. Overloading the tires can also
result in handling or steering problems, or brake failure.
Check the tire inflation pressure at least
once a month.
Check and adjust the tire inflation pres-
sure when the tires are cold (Y page 129).
Checking tire inflation pressure man-
ually Follow the steps below to achieve correct
tire inflation pressure:
X Remove the cap from the valve on one tire.
X Firmly press a tire gauge onto the valve.
X Read the tire inflation pressure on tire
gauge and check against the recommen-
ded tire inflation pressure on the Tire
and Loading Information placard on the
driver’s door B‑pillar (Y page 133). If
necessary, add air to achieve the recom-
mended tire inflation pressure.
X If you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of a pen. Then recheck the tire inflation
pressure with the tire gauge.
X Install the valve cap.
X Repeat this procedure for each tire.
Tire Pressure Monitoring System
(TPMS)* Your vehicle may be equipped with a
Tire
Pressure Monitoring System (TPMS).130
Tires and wheels>> Operation.
* optional
Page 133 of 222
It monitors the tire inflation pressure in
all four tires. A warning is issued to alert
you to a decrease in pressure in one or more of the tires.
The Tire Pressure Monitoring System
(TPMS) is equipped with a combination low
tire pressure/TPMS malfunction telltale in the instrument cluster. Depending on how
the telltale illuminates, it indicates a low
tire pressure condition or a malfunction in
the TPMS system itself:
R If the telltale illuminates continuously,
one or more of your tires is significantly
underinflated. There is no malfunction
in the TPMS.
R If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly.
The TPMS only functions on wheels that are
equipped with the proper electronic sen-
sors. G
WARNING
The TPMS does not indicate a warning for
wrongly selected inflation pressures.
Always adjust tire inflation pressure
according to the Tire and Loading Infor-
mation placard on the driver’s door B‑pil- lar.
The TPMS is not able to issue a warning due to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by
carefully applying the brakes and avoiding abrupt steering maneuvers. G
WARNING
Each tire should be checked monthly when
cold and inflated to the inflation pressure recommended by the vehicle manufacturer
on the Tire and Loading Information plac-
ard. If your vehicle has tires of a differentsize than the size indicated on the Tire and
Loading Information placard, you should
determine the proper tire inflation pres-
sure for those tires. As an added safety feature, your vehicle has
been equipped with a tire pressure moni-
toring system (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires is significantly underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driv-
ing on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure.
Underinflation also increases energy con-
sumption, reduces tire tread life, and may
affect the vehicle’s handling and stopping
ability. Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately
1 minute and then remain continuously
illuminated.
This sequence will continue upon subse-
quent vehicle start-ups as long as the mal-
function exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement Tires and wheels
131>> Operation.
Z
Page 134 of 222
or alternate tires and wheels allow the
TPMS to continue to function properly.
i If a condition causing the TPMS to mal-
function develops, it may take up to
10 minutes for the system to signal a mal-
function using the TPMS telltale flash-
ing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i Operating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the TPMS to malfunction.

WARNING
It is the driver’s responsibility to cali-
brate the TPMS on the recommended cold
inflation pressure. Underinflated tires
affect the ability to steer or brake and
might cause you to lose control of the vehi- cle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a
new level (e.g. because of different load or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
X Using the Tire and Loading Information
placard on the driver’s door B‑pillar
(Y page 133), make sure the tire infla-
tion pressure of all four tires is correct.
i Restart the TPMS after adjusting the
tire inflation pressure to the inflation
pressure recommended for the vehicle
operating condition. Tire pressure
should only be adjusted on cold tires.
Observe the recommended tire inflation
pressure on the Tire and Loading Infor-
mation placard on the driver’s door
B‑pillar (Y page 133). X

After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s speci-
fied range. Afterwards the current tire
inflation pressures are accepted as refer-
ence pressures and then monitored. Maximum tire inflation pressure

WARNING
Never exceed the max. tire inflation pres- sure. Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and energy con-
sumption, and are more likely to fail from
being overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase

For illustration purposes only. Actual
data on tires are specific to each vehicle and may vary from data shown in above
illustration.
This is the maximum permissible tire
inflation pressure :for the tire.
Always follow the recommended tire infla-
tion pressure (Y page 128) for proper tire
inflation. Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
1) The Tire and Loading Information plac- ard can be found on the driver’s door
B‑pillar. This placard tells you impor- tant information about the number of
people that can be in the vehicle and
the total weight that can be carried in
the vehicle. It also contains informa-
tion on the proper size and recommen-
ded tire inflation pressures for the
original equipment tires on your vehi-
cle.
2) The certification label, also found on the driver’s door B‑pillar, tells you
about the gross weight capacity of your
vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all
occupants, automotive fluids and
cargo. The certification label also
tells you about the front and rear axle
weight capacity, called the Gross Axle
Weight Rating (GAWR). The GAWR is the
total allowable weight that can be car-
ried by a single axle (front or rear).
Never exceed the GVWR or GAWR for
either the front axle or rear axle. :

WARNING
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver’s door B‑pillar. Overloading the tires can overheat them, possibly causing a
blowout. Overloading the tires can also
result in handling or steering problems, or brake failure.
Tire and Loading Information placard
i Data shown on Tire and Loading Infor-
mation placard example are for illus-
tration purposes only. Load limit data
are specific to each vehicle and may vary
from data shown in the following illus-
tration. Refer to Tire and Loading Infor-
mation placard on vehicle for actual data specific to your vehicle. The Tire and Loading Information placard
showing load limit information :is loca-
ted on the driver’s door B‑pillar
(Y page 133).
X Locate the statement “The combined
weight of occupants and cargo should
never exceed XXXX kg or XXXX lbs.” on the
Tire and Loading Information placard.
The combined weight of all occupants and
cargo/luggage should never exceed the
weight referenced in that statement. Seating capacity
The seating capacity gives you important
information on the number of occupants
that can be in the vehicle. The Tire and
Loading Information placard showing
seating capacity :is located on the
driver’s door B‑pillar (Y page 133).
i Data shown on Tire and Loading Infor-
mation placard example are for illus-
tration purposes only. Seating capacity
data are specific to each vehicle and may
vary from data shown in the following
illustration. Refer to Tire and Loading
Information placard on vehicle for
actual data specific to your vehicle.
Steps for determining correct load limit
The following steps have been developed as
required of all manufacturers under
Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the “National Traffic
and Motor Vehicle Safety Act of 1966”.
X Step 1: Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXXX kg or
XXXX lbs.” on your vehicle’s Tire and
Loading Information placard.
X Step 2: Determine the combined weight of
the driver and passenger that will be
riding in your vehicle.
X Step 3: Subtract the combined weight of
the driver and passenger from XXXX kilo- grams or XXXX lbs.
X Step 4: The resulting figure equals the
available amount of cargo and luggage 134
Tires and wheels>> Operation.
Page 137 of 222
load capacity. For example, if the “XXXX”
amount equals 540 lbs and there will be
one 150 lbs passenger in your vehicle, the
amount of available cargo and luggage
load capacity is 390 lbs
(540 lbs - 150 lbs = 390 lbs).
X Step 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.
i The maximum cargo compartment load
is 110 lbs (50 kg).
The following table shows examples on how
to calculate total and cargo load capaci-
ties with varying seating configurations
and number and size of occupants. The fol- lowing examples use a load limit of 540 lbs.
This is for illustration purposes only .
Make sure you are using the actual load
limit for your vehicle stated on the vehi-
cle’s Tire and Loading Information placard
(Y page 134).
The higher the weight of all occupants, the
less cargo and luggage load capacity is
available. Tires and wheels

390 lbs
Certification label
Even after careful determination of the
combined weight of all occupants and cargo
as to not exceed the permissible load
limit, you must make sure your vehicle
never exceeds the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for either the front or rear
axle. You can obtain the GVWR and GAWR
from the certification label. The certifi-
cation label can be found on the driver’s
door B‑pillar, see “Technical data”
(Y page 214).
Gross Vehicle Weight Rating (GVWR) means: The total weight of the vehicle, all occu-
pants, and all cargo must never exceed the
GVWR.
Gross Axle Weight Rating (GAWR) means:
The total allowable weight that can be car-
ried by a single axle (front or rear).
To assure that your vehicle does not exceed the maximum permissible weight limits
(GVWR and GAWR for front and rear axle),
have the loaded vehicle (including driver,
passenger, and all cargo) weighed on a
suitable commercial scale. Maximum tire load

Unidirectional tires offer added advan-
tages, such as better hydroplaning per-
formance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of rotation (spinning)
of the tire. Tire care and maintenance
G
WARNING
Regularly check the tires for damage. Dam- aged tires can cause tire inflation pres-
sure loss. As a result, you could lose control
of your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
Check the tire inflation pressure at least
once a month. For more information on
checking tire inflation pressure, see
“Recommended tire inflation pressure”
(Y page 128).
Tire inspection Every time you check the tire inflation
pressure, you should also inspect your
tires for the following
R excessive treadwear (Y page 137)
R cord or fabric showing through the tire’s
rubber
R bumps, bulges, cuts, cracks or splits in
the tread or side of the tire
Replace the tire if you find any of the above conditions. Life of tire G
WARNING
Tires should be replaced after 6 years,
regardless of the remaining tread.
The service life of a tire is dependent upon varying factors including but not limited
to
R driving style
R tire inflation pressure
R distance driven
Tread depth G
WARNING
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately 1
/ 16 in
(1.6 mm), we recommend that you do not allow your tires to wear down to that level. As
tread depth approaches 1
/ 8 in (3 mm), the
adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction var- ies widely.
Do not allow your tires to wear down too far. Adhesion properties on wet roads are
sharply reduced at tread depths of less than
1 / 8 in (3 mm).
Treadwear indicators (TWI) are required by law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of approx-
imately 1
/ 16 in (1.6 mm), at which point the
tire is considered worn and should be
replaced.
Recommended minimum tire tread depth:
Summer tires 1
/ 8 in (3 mm)
Winter tires 1
/ 6 in (4 mm) Tires and wheels

Treadwear indicator
:appears as a solid
band across the tread.
Storing tires !
Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact with oil, grease and fuels.
Cleaning tires !
Never use a round nozzle to power wash
tires. The intense jet of water can result in damage to the tire.
Always replace a damaged tire. Uniform Tire Quality Grading Stand-
ards
The Uniform Tire Quality Grading is a U.S.
Government requirement designed to give
drivers consistent and reliable informa-
tion regarding tire performance. Tire
manufacturers are required to grade tires
based on three performance factors: tread- wear
:, traction ;, and temperature
resistance =. Although not a Government
of Canada requirement, all tires made for
sale in North America have these grades
branded on the sidewall.
i For illustration purposes only. Actual
data on tires are specific to each vehicle and may vary from data shown in above
illustration.
Quality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example: Treadwear Traction Temperature
200 AA A
All passenger car tires must conform to
federal safety requirements in addition to
these grades.
Treadwear The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified U.S. government test course. For example, a tire graded 150 would wear one
and one-half (1 1
/ 2 ) 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 hab-
its, service practices and differences in
road characteristics and climate.
Traction G
WARNING
The traction grade assigned to this tire is based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics. 138
