This wearing in occurs mainly during the first
500 miles (805 km) and continues through
the first oil change interval.
It is recommended for the operator to observe
the following driving behaviors during the
new vehicle break-in period:
0 to 100 miles (0 to 161 km):
• Do not allow the engine to operate at idle
for an extended period of time.
• Depress the accelerator pedal slowly and
not more than halfway to avoid rapid accel-
eration.
• Avoid aggressive braking.
• Drive with the engine speed less than
3,500 RPM.
• Maintain vehicle speed below 55 mph
(88 km/h) and observe local speed limits.
100 to 300 miles (161 to 483 km):
• Depress the accelerator pedal slowly and
not more than halfway to avoid rapid accel-
eration in lower gears (1st to 3rd gears).
• Avoid aggressive braking.• Drive with the engine speed less than
5,000 RPM.
• Maintain vehicle speed below 70 mph
(112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shifting
manually (paddles or gear shift) at higher
rpms when possible.
• Do not perform sustained operation with
the accelerator pedal at wide open throttle.
• Maintain vehicle speed below 85 mph
(136 km/h) and observe local speed limits.
For the first 1500 miles (2414 km):
• Do not participate in track events, sport
driving schools, or similar activities during
the first 1500 mi (2414 km).

if necessary. Oil and fuel consumption may
be higher through the first oil change inter-
val. Running the engine with an oil level
below the add mark can cause severe engine
damage.AUTOMATIC
TRANSMISSION
WARNING!
•Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when exiting the ve-
hicle to guard against vehicle movement
and possible injury or damage.
•Your vehicle could move and injure you and
others if it is not in PARK. Check by trying
to move the transmission gear selector out
of PARK with the brake pedal released.
Make sure the transmission is in PARK
before exiting the vehicle.
•The transmission may not engage PARK if
the vehicle is moving. Always bring the
vehicle to a complete stop before shifting
to PARK, and verify that the transmission
gear position indicator solidly indicates
PARK (P) without blinking. Ensure that the
