With over 70,000 Citaro buses produced worldwide, Mercedes-Benz sets the standard for city transit reliability. The 100-hour PM keeps these precision machines running at peak performance.
Whether you operate Citaro diesel, hybrid, or eCitaro electric buses, consistent preventive maintenance separates high-performing fleets from those fighting constant breakdowns. Here's how to standardize your 100-hour service with CMMS automation.

Why CMMS for Mercedes-Benz Fleets
Mercedes-Benz buses are engineered for reliability—but only with proper maintenance tracking. CMMS transforms your PM program from reactive to proactive.
Hour-Based Triggers
Connect to telematics to auto-generate work orders at exactly 100 engine hours—no manual tracking needed.
Citaro-Specific Templates
Pre-built checklists for Citaro, Citaro G, CapaCity, and eCitaro models with correct inspection points.
Parts Integration
Link Mercedes-Benz OEM parts to service tasks. Know what's needed before the bus enters the shop.
Compliance Tracking
Document every inspection for FTA, DOT, and local transit authority audits with complete digital records.
AI Prioritization
Machine learning identifies which buses need attention first based on usage patterns and failure history.
Fleet Visibility
See PM status across your entire Mercedes-Benz fleet—upcoming, overdue, and in-progress—in real-time.

Frequently Asked Questions
What's included in a Mercedes-Benz 100-hour PM?
The 100-hour service covers engine/powertrain, brakes, steering, suspension, electrical systems, HVAC, safety systems, tires, and doors. For Citaro diesel models, this includes 50+ inspection points across these eight categories. eCitaro electric buses have a modified checklist focusing on HV battery diagnostics and thermal management.
How long does a 100-hour PM take?
Typical completion time is 60-90 minutes for diesel Citaro models and 45-60 minutes for eCitaro electric buses. Electric buses require less time due to fewer fluid checks and no exhaust system inspection. CMMS digital checklists help technicians work more efficiently.
Can CMMS handle both diesel and electric Mercedes-Benz buses?
Yes. Modern CMMS platforms support multiple vehicle types with model-specific templates. You can manage Citaro diesel, Citaro hybrid, and eCitaro electric buses from a single interface while maintaining appropriate inspection checklists for each variant.
How does hour-based PM tracking work?
CMMS connects to telematics (like Mercedes-Benz FleetBoard) to pull real-time engine hours. When a bus reaches 100 hours since last PM, the system automatically generates a work order and notifies your maintenance team. No manual tracking required.
What compliance documentation does CMMS provide?
Every completed PM generates timestamped records including technician name, inspection results, parts used, and completion time. These records satisfy FTA, DOT, and local transit authority audit requirements with exportable reports and digital signatures.
