G050500AUN Timing belt (if equipped)
Inspect all parts related to the timing belt
for damage and deformation. Replace
any damaged parts immediately.
G050600AUN-EA
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuelfiller cap is correctly replaced. G050700AUN
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.G050800AFD

Tyre speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger cars. The speed
rating is part of the tyre size desig-
nation on the sidewall of the tyre.This symbol corresponds to that
tyre's designed maximum safe oper-ating speed. G201003AEN-EA
3. Checking tyre life (TIN : Tyre
Identification Number)
Any tyres that are over 6 years,
based on the manufacturing date,
tyre strength and performance,
decline with age naturally (even
unused spare tyres). Therefore, thetyres (including the spare tyre)
should be replaced by new ones. You
can find the manufacturing date on
the tyre sidewall (possibly on the
inside of the wheel), displaying the
DOT Code. The DOT Code is a
series of numbers on a tyre consist-
ing of numbers and English letters.
The manufacturing date is designat-
ed by the last four digits (characters)
of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tyre size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1606 represents
that the tyre was produced in the
16th week of 2006. G201004AUN-EA
4. Tyre ply composition and material
The number of layers or plies of rub-
ber-coated fabric are in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and theletter "B" means belted-bias ply con-
struction.

WARNING - Tyre age
Tyres degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tyres generally be replaced
after six (6) years of normal
service. Heat caused by not cli-mates or frequent high loadingconditions can accelerate the
aging process. Failure to follow
this Warning can result in sud-
den tyre failure, which could
lead to a loss of control and an
accident involving serious
injury or death.
