Starting and Operating

New Vehicle Break-In

Caution
Follow these recommended guidelines
during the first 2 414 km (1,500 mi) of
driving this vehicle. Parts have a break-in
period and performance will be better in
the long run.
Avoid full throttle starts and abrupt
stops.
Do not exceed 4000 engine rpm.
Avoid driving at any one constant
speed, fast or slow.
Do not drive above
129 km/h (80 mph).
Avoid downshifting to brake or slow
the vehicle when the engine speed
will exceed 4000 rpm.
Do not let the engine labor. Never lug
the engine in high gear at low speeds.
With a manual transmission, shift to
the next lower gear. This rule applies
at all times, not just during the
break-in period.
Caution (Continued)
Do not participate in racing events,
sport driving schools, or similar
activities during this break-in period.
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) 0 183.
(Continued)
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.

Composite Materials

This vehicle may be equipped with parts

Warning
Exposed edges of parts containing carbon
fiber and other composite materials can
be sharp. Contact with these parts could
result in injury. Use caution to avoid
