Your actual highway mileage will probably be less than the highway estimate. You may get different mileage depending on how fast you drive, weather conditions and trip length. Compare the estimated mpg to the estimated mpg of other vehicles. Stated rates of acceleration are based upon manufacturer's track results and may vary depending on model, environmental and road surface conditions, driving style, elevation and vehicle load.ĮPA estimated fuel economy. See your Operator's Manual for information about resetting your vehicle's TPMS after correcting pressures, rotating or replacing your tires.īase MSRP excludes transportation and handling charges, destination charges, taxes, title, registration, preparation and documentary fees, tags, labor and installation charges, insurance, and optional equipment, products, packages and accessories. Mercedes-Benz recommends you check your tire pressure with a high-quality gauge (accurate to 1 psi) at least once per month and not to wait for the TPMS indicator to illuminate. The recommended inflation pressure listed in your vehicle's Operator's Manual or on the label inside the fuel door is a 'cold' pressure, meaning the car has been parked outside in ambient temperature conditions for at least an hour and driven less than one mile since being parked. This change alone could trigger the Tire Pressure Monitoring System (TPMS) warning lamp. When your tires are warm, whether from driving or being in an enclosed garage, their pressure will be significantly higher than after the vehicle has been parked outside on a cold winter day. There are a couple of reasons for this: (1) air can diffuse through a tire at a rate of 1-2 psi per month, (2) a tire typically loses 1-2 psi of pressure for every 10-degree (Fahrenheit) drop in ambient temperature.

It is normal for a properly functioning tire to lose air pressure over time. There are a few factors that might cause the tire pressure warning to illuminate, one of which is a leaking tire.
