Seat Belt Reminder warning light

This indicator comes on when you turn the ignition switch to the ON position. It reminds you and your passengers to fasten your seat belts. A beeper also sounds if you have not fastened your seat belt.

Low Oil Pressure warning light

This telltale indicates low engine oil pressure. If the telltale turns on while driving, stop the vehicle and shut off the engine as soon as possible. The engine can be severely damaged if this indicator flashes or stays on when the engine is running, or if a ‘‘CHECK ENGINE OIL LEVEL’’ message is on the multi-information display. Do not operate the vehicle until the cause is corrected. This telltale does not indicate how much oil is in the engine.

NOTICE: Do not use the vehicle until the failure has been solved. The turning on of the telltale does not indicate the amount of oil in the engine: the oil level can be checked on the display upon entering the vehicle and also by activating the “Oil level” function on the Information and Entertainment System.

Engine Coolant temperature too high warning light

The telltale lights up when the engine has overheated.

In normal driving conditions:

Stop the car, turn off the engine and check that the coolant level in the reservoir is not below the MIN mark.

In this case, wait for the engine to cool down, then slowly and carefully open the cap, fill with coolant and check that the level is between the MIN and MAX marks on the reservoir itself. Also check visually for any fluid leaks. Contact an authorized dealer if the telltale comes on when the engine is started again. If the vehicle is used under demanding conditions (e.g. in high-performance driving): slow down and, if the warning light stays on, stop the vehicle. Stop for 2 or 3 minutes with the engine running and slightly accelerated to facilitate better coolant circulation, then turn the engine off. Check that the coolant level is correct as described above.

Charging System warning light

This indicator has two functions:

1. If it comes on when the engine is running, the battery is not being charged, and you will see a ‘‘CHECK CHARGING SYSTEM’’ message on the multi-information display.

If the light remains on when the parking brake has been disengaged, and the fluid level is at the full mark on the master cylinder reservoir, it indicates a possible brake hydraulic system malfunction or that a problem with the Brake Booster has been detected by the Anti-Lock Brake System (ABS) / Electronic Stability Control (ESC) system.

Automatic Transmission Temperature warning light

If this happens, pull to the side of the road when it is safe, check which tire has lost pressure on the multi-information display, and determine the cause. If it is because of a flat tire, have the flat tire repaired as soon as possible. If two or more tires are underinflated, call a professional towing service.

2. If this indicator begins to flash, there is a problem with the tire pressure monitoring system (TPMS). You will also see a ‘‘CHECK TPMS SYSTEM’’ message on the multi-information display.
