Possible cause/consequence Service X must be carried out in ... days or after ... miles (kilometers) (컄 page 592).

Possible solution 왘 Have the maintenance service carried out by an authorized

Mercedes-Benz Center.

You have tried to Shift the automatic trans- mission to park position P using the gear selector lever although the vehicle is still in motion. Park Assist* is deactivated because the area around the sensors* in the front or the rear bumper (컄 page 601) is dirty. Park Assist* is deactivated because the battery voltage is insufficient. Park Assist* is switched off because the radar sensor system* is temporarily inop- erative due to electromagnetic interfer- ence near television and radio transmitter stations, toll stations, speed measuring systems, etc. Park Assist* is unavailable due to a mal- function.

왘 Stop your vehicle as soon as it is safe to do so. 왘 Shift the automatic transmission to park position P. 왘 Engage the electronic parking brake (컄 page 412). 왘 Clean the front and rear bumper (컄 page 601).

왘 Have the battery checked by an authorized Mercedes-Benz

Center.

왘 Wait until the message in the multifunction display disappears.

Parking Guidance Canceled

634

Possible cause/consequence Advanced Parking Guidance* is deactivat- ed because the area around the sensors* in the front or the rear bumper (컄 page 601) is dirty. Advanced Parking Guidance* is deactivat- ed because the battery voltage is insuffi- cient. Advanced Parking Guidance* is switched off because the radar sensor system* is temporarily inoperative due to electromag- netic interference near television and radio transmitter stations, toll stations, speed measuring systems, etc. Advanced Parking Guidance* has been canceled because: 앫 the vehicle is sliding 앫 the bumper became dirty in the area of

the sensors (컄 page 601)

앫 there has been a malfunction

Possible solution 왘 Clean the front and rear bumper (컄 page 601).

왘 Have the battery checked by an authorized Mercedes-Benz

Center.

왘 Wait to see if the interference is temporary or do not use Ad- vanced Parking Guidance*. Try in a location where the inter- fering transmission might not be present.

왘 Use Advanced Parking Guidance* again later. If the parking space symbol is not shown in the multi-function dis- play at a speed below 10 mph (16 km/h): 왘 Clean the bumpers (컄 page 601). or 왘 Restart the engine. or 왘 Contact an authorized Mercedes-Benz Center.

Possible cause/consequence Advanced Parking Guidance* The vehicle is in the end position. PRE-SAFE® itself has failed. All other occu- pant safety systems, such as the air bags, are still available. You attempt to activate DISTRONIC Plus*, Park Assist* or PRE-SAFE® Brake* even though you have switched off the radar sen- sors* on the vehicle. Your vehicle is due for maintenance service (컄 page 592). Service X must be carried within the next ... or before you have driven ... miles (kilome- ters).

Possible solution The display message disappears automatically.

왘 Contact an authorized Mercedes-Benz Center as soon as

possible.

왘 Check if the radar sensors* may be switched on (컄 page 302). 왘 Switch on the radar sensors* using the instrument cluster

control system.

왘 Have the maintenance service carried out by an authorized

Mercedes-Benz Center.

왘 Have the maintenance service carried out by an authorized

Tire Pressure Monitor Inoperative Tire Pressure Monitor Inoperative No Wheel Sensors

Possible cause/consequence You have attempted to start the engine while the automatic transmission was set to reverse gear R or drive position D. The Advanced TPMS or a wheel sensor is malfunctioning. The Advanced TPMS is deactivated because wheels without proper sensors were in- stalled.

Possible solution 왘 Shift the automatic transmission to park position P or neutral

position N (컄 page 417).

왘 Have the Advanced TPMS checked by an authorized

Mercedes-Benz Center.

왘 Have the wheel sensors installed by an authorized

Mercedes-Benz Center. As soon as all wheels with sensors have been mounted, the Advanced TPMS is switched back on after driving for several minutes.

636

Practical hints What to do if …?

Display Tire Pressure Monitor Currently Unavailable

Possible cause/consequence The Advanced TPMS is unable to monitor the tire inflation pressure due to: 앫 a nearby radio interference source 앫 the on-board voltage is too low 앫 excessive wheel sensor temperatures

Possible solution As soon as the causes for the malfunction are no longer present, the Advanced TPMS automatically becomes active again after a few minutes driving.

Warning!

Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire.

Follow recommended tire inflation pres- sures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adverse- ly affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) be- cause they are more likely to become punc- tured or damaged by road debris, potholes etc.

637

Possible cause/consequence The tire inflation pressure is being checked.

Possible solution 왘 Drive the vehicle for a few minutes.

The automatic transmission cannot be shifted out of the set position because of a malfunction.

If the automatic transmission is shift to drive position D (컄 page 417): 왘 Without changing the automatic transmission from drive position D, drive to an authorized Mercedes-Benz Center. If the automatic transmission is shift to neutral position N, re- verse gear R or park position P: 왘 Do not drive. 왘 Consult an authorized Mercedes-Benz Center.

Warning!

앫 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.

앫 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.

! The engine should not be operated with the coolant temperature above 248°F (120°C). Do- ing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.

During severe operating conditions, e.g. stop-and-go traffic, the coolant tem- perature may rise close to 248°F (120°C).

Caution Tire Defect

Possible cause/consequence Advanced TPMS: One or more tires are deflating. The respec- tive tire is shown in the multifunction display.

Possible solution 왘 Carefully bring the vehicle to a halt, avoiding

abrupt steering and braking maneuvers.

왘 Engage the electronic parking brake

(컄 page 412).

왘 If necessary, change the wheel (컄 page 696).

Warning!

Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire.

Follow recommended tire inflation pres- sures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adverse- ly affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) be- cause they are more likely to become punc- tured or damaged by road debris, potholes etc.
