The programmable auxiliaryheater should be switched onfor approximately 10 minutes at leastonce a month all year round. Thisprevents the water pump and heatermotor from seizing.
To avoid corrosion, the coolantin your vehicle should contain atleast 10 % antifreeze all year round.
Note:The programmable auxiliaryheater will only operate if there is atleast 7.5 litres of fuel in the fuel tank.
Note:The heating depends on theoutside air temperature.
Note:It is possible that when theprogrammable auxiliary heater isactivated, exhaust fumes may comefrom under the sides of the vehicle.This is normal.
Note:On vehicles with manualclimate control the heating of thevehicle interior is dependent on thetemperature, air distribution andblower control settings.
The programmable auxiliary heateroperates independently of the vehicleheater by heating the engine’scoolant circuit. It is fed from thevehicle fuel tank.
Used properly, the programmableauxiliary heater provides the followingbenefits:
•It preheats the interior of thevehicle.
•It keeps the windows clear of icein the event of frost and preventscondensation.
•It avoids cold starts and allows theengine to reach operatingtemperature sooner.
The programmable auxiliary heatermay also be used while the vehicle isin motion to help the vehicle heaterand warm up the interior morequickly.
To prevent the battery fromdischarging:
•Once the programmable auxiliaryheater has performed one heatingcycle, the next programmedheater time will only be carried outif the vehicle’s engine has beenstarted in between.
•After a heating cycle, the vehicleshould be driven for at least theperiod of the heating cycle.
Programming the auxiliaryheater
The auxiliary heater is programmedusing the information display. SeeInformation displays (page 96).

The diesel auxiliary heater (PTCelectrical heater) aids in warming theengine and the interior compartmenton vehicles with diesel engines. It isautomatically switched on or offdepending on the outsidetemperature, the coolanttemperature and the alternator load.
Fuel operated heater
The fuel operated heater aids inwarming the engine and the interiorcompartment on vehicles with apetrol or diesel engine. It isautomatically switched on or offdepending on the outsidetemperature and the coolanttemperature, unless it has beendeactivated by the driver.
When the fuel operated heater isoperating, a message appears in theinformation display.
The fuel operated heater can bedeactivated using the informationdisplay. See Information displays(page 96).
ELECTRIC SUNROOF
WARNING
Before operating the electricsunroof you should verify it isfree of obstructions and ensure thatchildren and/or pets are not in theproximity of the sunroof opening.Failure to do so could result in seriouspersonal injury. It is the primaryresponsibility of the supervising adultsto never leave a child unattended ina vehicle and to never leave the keysin an unattended vehicle.
Note:When the switches areoperated often during a short periodof time, the system might becomeinoperable for a certain time toprevent damage due to overheating.
Note:The electric sunroof can alsobe operated with the ignition off viathe global opening and global closingfunction. See Global opening andclosing (page 50).

Cold/hot engine
WARNING
At temperatures below -20 ºC,turn the ignition key to positionII for at least one second. Thisensures that maximum fuel pressureis established.
Depress the clutch pedal fully andstart the engine without touching theaccelerator.
If the engine does not start within 15seconds, wait for a short period andrepeat the procedure.
If the engine does not start afterthree attempts wait 10 seconds andfollow the Flooded engineprocedure.
If starting difficulty is experienced attemperatures below -25ºC, depressthe accelerator pedal ¼ to ½ of itstravel to assist starting.
Flooded engine
Depress the clutch pedal fully.
Slowly depress the accelerator fully,hold it in this position and start theengine.
If the engine does not start repeatthe Cold/hot engine procedure.
Vehicles with a Flexfuelengine
Starting at low ambienttemperatures
When the temperature is expectedto be lower than -15°C and thevehicle is filled with bio ethanol E 85,an engine block heater should beused to facilitate starting.
If the temperature is expected toremain below -15°C, it isrecommended that you increase theproportion of petrol in the tank bytopping up with 95 octane unleadedpetrol if the tank is not already full.About 10 litres of petrol will reducethe proportion of bio ethanol E 85 ina ¾ full tank from 85% to 70%.
If, at very low temperatures, the tankis filled with only bio ethanol E 85 andthere is no way to use an engineblock heater, you may experiencedifficulties starting the engine.
If the engine fails to start, proceed asfollows:
1.Depress the accelerator pedal 1/3to ½ of its travel.
2.Turn the ignition key to positionIII.
3.Release the ignition key as soonas the engine has started andrelease the accelerator pedalgradually as the engine speedincreases.
4.If the engine fails to start, depressthe accelerator pedal fully andrepeat steps 2 and 3.

Vehicles with a manualtransmission
Note:If the clutch pedal is notdepressed, a message appears inthe information display.
Depress the clutch pedal.
Vehicles with an automatictransmission
Note:If the brake pedal is notdepressed, a message appears inthe information display.
Depress the brake pedal.
All vehicles
Push the ignition switch in and turn itto switch on the ignition and to startthe engine.
Once the system recognizes apassive key, the engine can bestarted. If no passive key is detected,PASSIVE KEY NOT DETECTEDwill appear in the information display.
Starting the engine with aspare key
Assemble the spare key. SeeKeyless entry (page 44).
Insert the spare key into the ignitionswitch.
Push the ignition switch in and turn itto switch on the ignition and to startthe engine.

SWITCHING OFF THE
ENGINE
Vehicles with aturbocharger
CAUTION
Do not switch the engine offwhen it is running at high speed.If you do, the turbocharger willcontinue running after the engine oilpressure has dropped to zero. Thiswill lead to premature turbochargerbearing wear.
Release the accelerator pedal. Waituntil the engine has reached idlespeed and then switch it off.
ENGINE HEATER
CAUTION
Make sure you disconnect thepower cable from the engineheater connector before drivingaway.
Note:Only use the engine heater intemperatures below -10°C (14°F).
Note:The engine heater connectoris located in the radiator grille at thefront of your vehicle.
Connect the engine heater for 2 to3 hours before starting the engine.
