Checking Tyres
To safely operate your vehicle, your tyres must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■
Inflation guidelines
Properly inflated tyres provide the best combination of handling, tread life, and
comfort. Refer to the driver’s doorjamb label for the specified pressure.
Underinflated tyres wear unevenly, adversely affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tyres make your vehicle ride harshly, are more prone to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tyres. If one looks lower than the
others, check the pressure with a tyre gauge.
At least once a month or before long trips, use a gauge to measure the pressure in
all tyres. Even tyres in good condition can lose 10–20 kPa (0.1–0.2 bar, 1–2 psi) per
month.
■
Inspection guidelines
Every time you check inflation, also examine the tyres and valve stems.
Look for:
• Bumps or bulges on the side or in the tread. Replace the tyre if you find any cuts,
splits, or cracks in the side of the tyre. Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have a dealer check the wheel alignment.
• Excessive tread wear.
2 Wear Indicators P. 544
• Cracks or other damage around valve stem.
1Checking Tyres
Measure the air pressure when tyres are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1.6 km (1 mile). If
necessary, add or release air until the specified
pressure is reached.
If checked when hot, tyre pressure can be as much as
30–40 kPa (0.3–0.4 bar, 4–6 psi) higher than if
checked when cold.
Whenever tyre pressure is adjusted, you must
calibrate the deflation warning system.

WARNING
Using tyres that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instructions in this owner’s
manual regarding tyre inflation and
maintenance.

uuChecking and Maintaining TyresuWear Indicators
Maintenance
Wear Indicators
The groove where the wear indicator is
located is about 1.6 mm (about 1/16 inch)
shallower than elsewhere on the tyre. If the
tread has worn so that the indicator is
exposed, replace the tyre.
Worn out tyres have poor traction on wet
roads.
Tyre Service Life
The life of your tyres is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pressure, maintenance history, speed, and
environmental conditions (even when the tyres are not in use).
In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tyres reach five
years old. All tyres should be removed from service after 10 years from the date of
manufacture, regardless of their condition or state of wear.
1Checking Tyres
Have a dealer check the tyres if you feel a consistent
vibration while driving. New tyres and any that have
been removed and reinstalled should be properly
balanced.
High speed driving
We recommend that you do not drive faster than the
posted speed limits and conditions allow. If you drive
at sustained high speeds (over 160 km/h/100 mph),
adjust the cold tyre pressures as shown below to
avoid excessive heat build up and sudden tyre failure.

Maintenance
Tyre and Wheel Replacement
Replace your tyres with radials of the same size, load range, speed rating, and
maximum cold tyre pressure rating (as shown on the tyre’s sidewall). Using tyres of
a different size or construction can cause certain vehicle systems such as the ABS
and Vehicle Stability Assist (VSA) system to work incorrectly.
It is best to replace all four tyres at the same time. If that isn’t possible, replace the
front or rear tyres in pairs.
Make sure that the wheel’s specifications match those of the original wheels.

WARNING
Installing improper tyres on your vehicle
can affect handling and stability. This can
cause a crash in which you can be seriously
hurt or killed.
Always use the size and type of tyres
recommended in the tyre information label
on your vehicle.

uuChecking and Maintaining TyresuTyre Rotation
Maintenance
Tyre Rotation
Rotating tyres according to the maintenance schedule helps to distribute wear more
evenly and increase tyre life.
■
Tyres without rotation marks
Rotate the tyres as shown here.
■
Tyres with rotation marks
Rotate the tyres as shown here.
1Tyre Rotation
Tyres with directional tread patterns should only be
rotated front to back (not from one side to the other).
Directional tyres should be mounted with the
rotation indication mark facing forward, as shown
below.
When the tyres are rotated, make sure the air
pressures are checked.
Whenever tyres are rotated, you must initialise the
deflation warning system.
2 Deflation Warning System P. 387
Wheel nut torque for the tyres that come standard-
equipped with your vehicle is as follows.

Maintenance
Snow Traction Devices
If driving on snowy or frozen roads, mount winter tyres, or tyre chains; reduce
speed; and maintain sufficient distance between vehicles when driving.
Be particularly careful when operating the steering wheel or brakes to prevent
skidding.
Use tyre chains, winter tyres, or all season tyres when necessary or according to the law.
When mounting, refer to the following points.
For winter tyres:
• Select the size and load ranges that are the same as the original tyres.
• Mount the tyres to all four wheels.
For tyre chains:
• Consult a dealer before purchasing any type of chains for your vehicle.
• Install them on the front tyres only.
• Because your vehicle has limited tyre clearance, we strongly recommend using the
chains listed below:
*1:Original tyre size is mentioned on the tyre information label on the driver’s
doorjamb.
• Follow the chain manufacturer’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not touch the brake lines or suspension.
• Drive slowly.

1Snow Traction Devices
Traction devices that are the wrong size or improperly installed
can damage your vehicle’s brake lines, suspension, body, and
wheels. Stop driving if they are hitting any part of the vehicle.
According to the EU legislation for tyres, when winter tyres are
used, it is necessary to affix a sticker with the allowable max.
speed of the winter tyres clearly in the field of view of the
driver, if the designed max. speed of vehicle is higher than the
allowed max. speed of winter tyre. A sticker is obtainable from
your tyre dealer. If you have any question, consult a dealer.
When tyre chains are mounted, follow the chain manufacturer’s
instructions regarding vehicle operational limits.
Use tyre chains only in an emergency or when they
are legally required for driving through a certain area.
Use greater caution when driving with tyre chains on snow or ice. They
may have less-predictable handling than good winter tyres without chains.
If your vehicle is equipped with summer tyres, be aware
that these tyres are not designed for winter driving
conditions. For more information, contact a dealer.

WARNING
Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.
Follow all instructions in this owner’s
manual regarding the selection and use of
tyre chains.
