ENGINE BREAK-IN RECOMMENDATIONS

Engine break 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.
Press the accelerator pedal slowly and not

more than halfway to avoid rapid
acceleration.
Avoid aggressive braking.

Drive with the engine speed below

3,500 RPM.
Maintain vehicle speed below 55 mph

(88 km/h) and observe local speed limits.

STARTING AND OPERATING

100 to 300 miles (161 to 483 km):
Press the accelerator pedal slowly and not

more than halfway to avoid rapid accelera-
tion in lower gears (FIRST to THIRD gears).
Avoid aggressive braking.

Drive with the engine speed below

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
RPM 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 1,500 miles (2,414 km):
Avoid high engine and driveline loading.

NOTE:
Check engine oil with every refueling and add if
necessary. Oil and fuel consumption may be
higher through the first oil change interval.
Running the engine with an oil level below the
add mark can cause severe engine damage.

AUTOMATIC TRANSMISSION

You must press and hold the brake pedal while
shifting out of PARK.
WARNING!
Never use the PARK position as a substi-

tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle
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.
