Driving and Operating
Caution (Continued)
.
Check engine oil with
every refueling and add if
necessary. Oil and fuel
consumption may be
higher than normal during
the first
2 414 km (1,500 mi).
.
To break in new tires,
drive at moderate speeds
and avoid hard cornering
for the first
322 km (200 mi). New tires
do not have maximum
traction and may tend
to slip.
.
New brake linings also
need a break-in period.
Avoid making hard stops
during the first
322 km (200 mi). This is
recommended every time
brake linings are replaced.
.
Should the vehicle be used
for racing or competitive
driving (after break-in), the
rear axle lubricant must be
replaced beforehand.
See Track Events and
Competitive Driving (V-Series
and V-Series Blackwing)
On new vehicles, the various
mechanical and electrical
systems experience a
“
break-in
”
period during the
first 6,400 km (4,000 miles) of
routine driving. As the vehicle
is driven, the mechanical
systems adjust to provide
optimal fuel economy and
transmission shift
performance.
Electrical systems will adapt
and calibrate during the
break-in period. A one-time
occurrence of clicks and
similar vehicle noises is normal
during this process.
Normal driving charges the
vehicle
’
s battery to achieve
the best operation of the
vehicle, including fuel
economy.
