I too recently picked up my new 2019 170 4x4 from Orange County, CA and drove it back to Seattle, WA. I avoided freeways where possible and didn't use cruise control, it wasn't easy to vary speed and RPM but took my time over 3 days/1200 miles and many scenic routes
.
After the first day or so on some stretches I'd used the cruise but changing speed by the thumb button on the steering wheel (+/- 1 mph, from 10/15 mph under the speed limit to over 5mph beyond the limits)...likely to the annoyance of folks behind me...anyway all was fine made it home with many shopping stops for conversion gears along the way.
Here is the break-in notes from the 2019 Sprinter Manual...safe trip!
Breaking-in notes
Protect the engine during the first 1,000 miles
(1,500 km) by:
- driving at varying road and engine speeds.
- shifting to the next gear up when or before the tachometer needle is 2/3 of the way to the
red area.
- avoiding stress on the vehicle such as driving at full throttle.
- not shifting manually to a lower gear to brake.
- after 1,000 miles (1,500 km), gradually increasing the engine speed and accelerate the vehicle up to full speed.
- vehicles with automatic transmission: not depressing the accelerator pedal beyond the pressure point (kickdown).
This also applies if the engine or parts of the drivetrain have been replaced.
Also observe the following breaking-in notes:
- The sensors of the ESP® driving safety system adjust automatically while a certain distance is being driven after the vehicle has been delivered or after repairs. Full system effectiveness is not reached until the end of this teach-in process.
- New or exchanged brakepads, brake discs and tires only provide optimal braking and bonding after several hundred kilometers. Until then, compensate for the reduced braking effect by applying greater pressure to the brake pedal.
