Important safety notes

Useful information i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's

Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safetyrelated systems and functions.

i Read the information on qualified specialist workshops: ( Y page 24).

Important safety notes

G WARNING

The driver's concentration must always be directed primarily at road traffic.

For your safety and the safety of others, selecting features through the multifunction steering wheel should only be done by the driver when traffic and road conditions permit it to be done safely.

Bear in mind that at a speed of only 30 mph

(approximately 50 km/h), the vehicle covers a distance of 44 feet (approximately 14 m) per second.

G WARNING

No messages will be displayed if either the instrument cluster or the multifunction display is inoperative.

As a result, you will not be able to see information about your driving conditions, such as

R speed

R outside temperature

R warning/indicator lamps

R malfunction/warning messages

R failure of any systems

Driving characteristics may be impaired.

If you must continue to drive, do so with added caution. Contact an authorized Mercedes-

Benz Center as soon as possible.

G WARNING

Malfunction and warning messages are only displayed for certain systems and are intentionally not very detailed. The malfunction and warning messages are simply a reminder with respect to the operation of certain systems. They do not replace the owner's and/or driver's responsibility to maintain the vehicle's operating safety. Have all required maintenance services and safety checks performed on the vehicle. Bring the vehicle to an authorized Mercedes-Benz Center to address the malfunction and warning messages.

G WARNING

All categories of messages contain important information which should be taken note of and, where a malfunction is indicated, addressed as soon as possible at an authorized Mercedes-Benz Center.

Failure to repair the condition noted may cause damage not covered by the Mercedes-

Benz Limited Warranty, or result in property damage or personal injury.

For an illustration of the instrument cluster, see ( Y page 29).

Coolant temperature display

G WARNING

Driving when your engine is overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned.

Steam from an overheated engine can cause serious burns which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it.

Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

! A display message is shown if the coolant temperature is too high.

If the coolant temperature is over

248 ‡(120 †), do not continue driving. The engine will otherwise be damaged.

The coolant temperature gauge is in the instrument cluster on the left-hand side

( Y page 29).

Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 248 ‡ (120 †).

Tachometer

! Do not drive in the overrevving range, as this could damage the engine.

The red band in the tachometer indicates the engine's overrevving range.

The fuel supply is interrupted to protect the engine when the red band is reached.

Outside temperature display

G WARNING

The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose.

Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges.

The outside temperature display is in the multifunction display ( Y page 211).

Changes in the outside temperature are displayed after a short delay.
