ENGINE BREAK-IN RECOMMENDATIONS — SRT

The following tips will be helpful in obtaining optimum performance and maximum durability for your new SRT Vehicle.

Despite modern technology and World Class manufacturing methods, the moving parts of the vehicle must still wear in with each other. 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 acceleration.

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 acceleration 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 1,500 miles (2,414 km):

Do not participate in track events, sport driving schools, or similar activities during the first 1500 mi (2414 km).

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.
