The reducing agent is added by the service
center within the context of regular mainte‐
nance. Provided you observe this maintenance
schedule, it is normally necessary to replenish
the fluid once between maintenance appoint‐
ments.
It may be necessary to have the fluid replen‐
ished several times under particular circum‐
stances, for example, if the vehicle is driven in
a particularly sporty style or if it is driven at
high altitudes.The reducing agent must be replenished as
soon as the reserve display appears in the in‐
strument cluster to avoid not being able to re‐
start the engine.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it is possible that reducing agent may also need to be re‐
plenished between regular maintenance ap‐
pointments if it is exposed to temperatures be‐
low + 23 ℉/- 5 ℃. In this case, add reducing
agent only immediately before starting to drive.
The need to replenish it is indicated by the Re‐
serve display in the instrument cluster.
At temperatures below + 12 ℉/- 11 ℃ the fill
level in some cases cannot be measured.
After adding reducing agent, the reserve dis‐
play is displayed only until the fill level can be
measured again.
Replenishing Diesel exhaust fluid
yourself in exceptional cases
You can replenish reducing agent yourself in
exceptional cases, e.g., to get to the service
center.
Avoid contact with Diesel exhaust fluid
Do not come into contact with the reduc‐
ing agent. Otherwise, skin or eye irritations
may result.◀
Handling Diesel exhaust fluid

closed spaces, ensure good ventilation. When
the bottle or container is opened, acrid smell‐
ing fumes may escape.◀
