Maintenance Schedule
The 2027 GLC Electric uses ASSYST Plus, an onboard system that tracks
condition- and time-based maintenance requirements and alerts you when
service is due. Like other Mercedes-Benz vehicles, the GLC Electric
follows Service A and Service B maintenance categories. Because it is
fully electric, it does not require engine oil changes, spark plug
replacement, or other combustion-engine maintenance.
Service A
Service A is generally the first scheduled maintenance visit,
occurring at approximately 10,000 miles or 1 year, whichever comes
first. Subsequent Service A visits generally occur every 20,000
miles or 2 years after the previous Service A.
For electric Mercedes-Benz vehicles, Service A typically includes
applicable maintenance such as:
- Fluid level checks and corrections
- Tire inflation and condition checks
- Brake component inspection
- Multi-point vehicle inspection
- Windshield wiper inspection and replacement as needed
- High-voltage system checks, as applicable
- ASSYST Plus maintenance counter reset
Service B
Service B generally occurs at approximately 20,000 miles or 1 year
after the preceding Service A. Subsequent Service B visits
generally occur every 20,000 miles or 2 years after the previous
Service B.
Service B includes applicable Service A inspections and additional
maintenance items such as:
- Cabin dust and combination filter replacement
- Activated charcoal filter replacement, when due
- Brake fluid exchange
- Fluid level checks and corrections
- Tire inflation and condition checks
- Multi-point vehicle inspection
-
Applicable high-voltage system and thermal management checks

Electric:

2027 GLC Electric SUV specs and features
Routine Service and What to Expect
Because the GLC Electric SUV has no combustion engine, it does not
require engine oil changes, spark plug replacement, or exhaust system
maintenance. For transmission-related maintenance, our service team can
review the vehicle's service requirements. Mercedes-Benz lists cabin
filter replacement, brake fluid service, wiper blades, and inspections
among its EV service package items.
Depending on what is due, a Service A or Service B appointment may
include the following maintenance:
Cabin filtration
The dust filter and activated charcoal filter are replaced when
due. These filters help reduce airborne particles and odors inside
the cabin.
Brake fluid
Brake fluid absorbs moisture over time regardless of how often the
brakes are used mechanically. Regenerative braking can reduce
friction-brake use, but brake fluid still requires maintenance.
The GLC Electric offers four settings: D Auto, D+, D, and D-.
Wiper blades
Wiper blades are replaced when needed to maintain clear sightlines
and support the rain-sensing windshield wiper system.
Multi-point inspection
During a multi-point inspection, a trained technician checks the
vehicle's key systems. Let your service advisor know about any
concerns with tire wear, lighting, the charging port, or
suspension components.
Ask our service team about tire care and other wear-related maintenance
based on your driving habits and tire configuration. The GLC Electric is
fitted with 235/50R20 front and 265/45R20 rear all-season Extended
Mobility tires from the factory.

components are subject to the applicable provisions of the
4-year/50,000-mile New Vehicle Limited Warranty. Coverage of
individual components is governed by the Mercedes-Benz warranty
documentation.
Roadside Assistance: Mercedes-Benz Roadside

Common Ownership Questions
How often does the GLC Electric need to visit a service center?
Mercedes-Benz generally schedules the first Service A at approximately
10,000 miles or 1 year, followed by Service B at approximately 20,000
miles or 1 year after Service A. Each service category generally repeats
every 20,000 miles or 2 years, with ASSYST Plus providing reminders.
Tire inspections and visits for specific concerns may also be necessary.
Does regenerative braking reduce brake wear?
Yes. Regenerative braking can reduce friction-brake use, which may help
reduce brake pad and rotor wear. The four settings—D Auto, D+, D, and
D-—provide different recuperation behavior, with D+ allowing coasting
without lift-off regeneration. Brake fluid still requires replacement
according to the applicable maintenance schedule.
Can I charge the GLC Electric at home?
The vehicle supports AC charging at 9.6 kW through a standard J1772
connector, which is compatible with a home Level 2 charger. A full
0-100% charge on AC takes approximately 12.5 hours. For public charging,
the GLC Electric uses the North American Charging Standard (NACS)
connector and supports DC fast charging at up to 330 kW on compatible
800V infrastructure. Charging from 10 to 80 percent can take
approximately 22 minutes under suitable conditions. Actual charging
times vary by location, equipment, battery conditions, and other
operating factors.
What is the EPA-estimated range of the 2027 GLC Electric?
The GLC 400 4MATIC Electric SUV offers an EPA-estimated 331 miles of
range with all-season tires. Actual driving range varies with conditions
and vehicle use. MBUX Navigation with Electric Intelligence (available
as a Digital Extra for 7 years) helps plan routes with charging stops
based on battery state, destination, and route conditions.
How does the front disconnect unit affect ownership?
The front motor disconnect unit allows the GLC Electric to decouple the
front motor under low-load conditions to help reduce energy consumption.
The system operates automatically without driver input. Any maintenance
requirements should follow the vehicle's applicable maintenance
documentation.
Is the GLC Electric suitable for towing?
The GLC 400 4MATIC Electric SUV is rated to tow up to 5,291 lbs. If you
plan to tow regularly, discuss trailer hitch installation and any
towing-specific inspection intervals with the service team at
Mercedes-Benz of Tuscaloosa.
