Vehicle Operation and Controls

The illustrated “At a glance” section maps the cockpit before the manual moves into detailed operating guidance. It locates the DIRECT SELECT lever, paddle shifters, PARKTRONIC display, climate controls, ignition and Start/Stop button, light switch, steering-wheel adjustment, sunroof and tailgate switches, mirror controls, and window switches. The steering-wheel chapter explains how the buttons move through the standard, AMG, off-road, audio, navigation, DISTRONIC, message-memory, settings, trip-computer, and telephone menus.

Opening and comfort sections cover SmartKey/KEYLESS-GO behavior, mechanical emergency access, automatic locking, tailgate opening-angle memory and emergency release, convenience opening and closing, plus reset and fault-response procedures for the windows and sunroof. Seat, mirror, heating, ventilation, and memory functions are separated by equipment level. Climate-control coverage distinguishes dual-zone and multi-zone systems and includes automatic regulation, dehumidification, defrosting, air distribution and airflow, rear controls, MONO synchronization, recirculation, residual heat, and vent adjustment.

The driving chapter handles gasoline and diesel starting logic, hill-start assist, transmission positions, shift-range restriction, kickdown, paddle-shifter use, and AMG C/S/M programs. On 4MATIC vehicles, it explains permanent all-wheel drive with ESP® and 4ETS. Optional off-road material extends to DSR, the off-road drive program, LOW RANGE shifting, and Off-Road Pro differential-lock operation. AIRMATIC/ADS, DISTRONIC, PARKTRONIC, the rear-view camera, Blind Spot Assist, off-road driving, and trailer towing are presented with their operating limits and related display messages.

Detailed COMAND APS, navigation, audio, Bluetooth®, and Voice Control operation is not self-contained here. This manual covers the steering-wheel interface and multifunction-display information, then directs the operator to separate system instructions for the underlying functions.

Technical Data, Safety, and Manual Scope

The technical-data section identifies VIN and engine-number locations and provides model-specific categories for approved engine oils, viscosity, fluid capacities, gasoline and diesel requirements, AdBlue®, coolant, brake fluid, R134a refrigerant with PAG lubricant, washer fluid, wheel/tire combinations, emergency spare wheels, vehicle dimensions, and roof-load data. Tire-pressure guidance points to the vehicle-specific B-pillar placard and fuel-filler-flap tables rather than treating one pressure as universal. Service types and intervals remain in the separate Service Booklet; fuse-box locations are covered here, while ratings are listed in the allocation chart stored with the vehicle tool kit.

Safety coverage includes SRS monitoring, adaptive dual-stage front air bags, side and window-curtain air bags, the U.S.-market Occupant Classification System, Canadian BabySmart™ equipment, Emergency Tensioning Devices, belt-force limiters, PRE-SAFE®, NECK-PRO, LATCH/ISOFIX, Top Tether, child-proof locks, and the interaction of ABS, BAS, EBD, ESP®, and 4ETS. Display-message and warning-lamp tables organize restraint, brake, engine, lighting, tire, and vehicle faults by problem, cause, consequence, and response.

Several cautions matter when the vehicle is tested or serviced. A 4MATIC vehicle must not be towed with one axle raised, and performance testing requires a two-axle dynamometer to avoid transfer-case, drivetrain, or brake-system damage. Off-Road Pro differential locks are not intended for paved roads, where the locked drivetrain sharply reduces steerability and can bind or chatter. Contaminated or diluted AdBlue® can damage the BlueTEC exhaust aftertreatment system.

This is an operator’s manual, not a workshop repair manual. Its scope is vehicle operation, owner checks, driver-level troubleshooting, roadside procedures, and repair planning rather than component teardown or overhaul. Detailed service schedules are in the separate Service Booklet, and hybrid-specific operation and safety information requires the separate HYBRID Supplemental Operating Instructions. Repair work involving SRS/OCS components, interconnected electronics, 4MATIC drivetrain or brake systems, and refrigerant circuits should be handled by qualified technicians.
