Anyone know how to reset tire pressure monitor baseline?
I just looked in the owners manual for mine and reset it. With an empty van I run 49 all around and not 70 in the rear. I want the TPMS to be set for that when I am running that way.
From the 2016 manual (with a little hand formatting to fix the cut and paste - hopefully acceptable):
Restarting the tire pressure monitor
When you restart the tire pressure monitor, the currently set tire pressure are taken as reference values for monitoring.
In most cases, the tire pressure monitor detects
the new reference values automatically, e.g.
after you have:
- changed the tire pressure
- changed wheels or tires
- installed new wheels or tires
However, you can also define reference values
manually as described here.
Before restarting the tire pressure monitor:
- Set the tire pressure to the value recommended on the Tire and Loading Information plac
ard or the tire pressure table on the B-pillar on the driver's side (see page 250).
Observe the notes on tire pressure when doing so (see page 250).
- Make sure that the tire pressure is correct on all four wheels.
Restarting the tire pressure monitor (vehicles without steering wheel buttons):
- Turn the Smart Key to position 2 in the ignition lock.
- Press the "M" menu button on the instrument cluster repeatedly until the display shows the following message:
CAL- TPMS
- Press the "plus" button on the instrument cluster.
The display shows:
OK TPMS
The tire pressure monitor activation process has begun. The tire pressures measured for
the individual wheels are stored as the new reference values, provided that the tire pres-
sure monitor considers them to be plausible.
If you wish to cancel the restart:
- Press the "minus" button or the "M" menu button on the instrument cluster.
The activation process is canceled automatically if 30 seconds elapse without input.
Restarting the tire pressure monitor (vehicles with steering wheel buttons):
- Turn the key to position 2 in the ignition lock.
- Press the "next" or "previous" menus button on the steering wheel until the standard display (see page 167) appears in the display.
- Press the "up" arrow or "down" arrow button on the steering wheel repeatedly until the current pressure of the individual tires is displayed or the display shows the following message:
Tire pres. displayed after driving for several minutes
- Press the "O" reset button on the instrument cluster.
The display shows the following message:
Monitor current tire pressure?
- Press the "plus" button on the steering wheel.
The display shows the following message:
Tire pres. monitor reactivated
The tire pressure monitor activation process has begun. The tire pressures measured for the individual wheels are stored as the new reference values, provided that the tire pressure monitor considers them to be plausible.
If you wish to cancel the restart:
- Press the X button on the steering wheel.
