Maintenance - SMART Fortwo 451 Series Introduction Into Service Manual

Maintenance

Maintenance concept
The maintenance concept mainly differs in terms
of the maintenance performed on the drive
system. In contrast to a vehicle driven by a
combustion engine, the electric drive is largely
maintenance free.
In addition to a visual inspection for damage and
leaks as well as checking, refilling or replacing
operating fluids and electronic battery testing,
only the desiccant cartridge of the high-voltage
battery has to be replaced.
Maintenance interval
The maintenance interval for the smart fortwo
electric drive is specified as follows:
1 year or 20,000 km
i Note
One special consideration is that the number of
operating hours of the brake booster vacuum
pump must be checked using
servicing at the following intervals:
• Up to 4 years/125,000 km: every 2 years
• After 4 years/125,000 km: annually
