224 Car care
Flat spotting
All tires get hot, especially on long journeys
or when the car is driven hard. After the car
has been parked with hot tires and the tires
have cooled down, a flat spot can form in the
tire, where it is in contact with the ground.
The same can occur if the car has not been
moved for a long time.
Flat spots can cause vibration that can be
felt through the steering wheel, similar to
that experienced when the wheels need bal-
ancing. Flat spots of this type disappear
once the tires get hot again, usually after
10–15 miles (20–25 km) of driving at cruis-
ing speed.
Safety belts
A check should be made periodically to
ensure that the safety belts are working
properly.
• Hold the diagonal strap and pull it sharply.
The safety belt should lock and it should
not be possible to withdraw it further.
A sharp tug on the belt should cause the
inertia reel to lock. Check the floor anchor-
age points for corrosion damage. If a belt is
worn or has any fraying edges, it should be
replaced.
Safety belts must not come into contact with
substances such as polishes, oil or chemi-
cals. If the belts get dirty, wash them with
warm water and a detergent or have them
replaced.
WARNING
Safety belts and belt pretensioners that
were in use in a serious collision must be
replaced even if they are not visibly
damaged.
No attempt must be made to repair, or
modify the function of, safety belts.
