Ignition positions The car's electrical system can be set in different levels/positions and in this way make the differ-ent functions available.
In order to facilitate the use of a limited number of functions with the engine switched off, thecar's electrical system can be set in 3 different levels - 0, I and II. These levels are described
with the denomination "ignition position" throughout the owner's manual. The following table shows the functions available in each ignition position/level:
Level Functions
0 •Odometer, clock and temperature gauge are illuminated.
• Power seats can be adjusted.
• The power windows can be used.
• The centre display is started andcan be used.
• It is possible to start the audio.
The functions are time-controlled inthis ignition position and are switchedoff automatically after a period of time.
I •Panorama roof, power windows,12V socket in the passenger com-partment, navigation, phone, venti-lation fan and windscreen wiperscan be used.
• Power seats can be adjusted.
• 12 V sockets in the cargo areacan be used.
• The audio is started automaticallyif it was running when the car wasleft.
Power is taken from the battery inthis ignition position.Level Functions
II •The headlamps come on.
• Warning/indicator lamps illuminate for 5 seconds.
• Several other systems are acti-vated. However, heating in seatcushions and the rear window canonly be activated after the car hasbeen started.
This ignition position consumes alot of current from the battery andshould therefore be avoided!

Starting the car
The car is started using the remote control key and the start knob in the tunnel console.
Start knob in the tunnel console.
The remote control key is not physically used when starting the car since the car is equippedwith support for keyless starting (Passive Start). To start the car:
1. The remote control key must be inside the car. For cars with Passive Start, the key needs to be located in the front part of thepassenger compartment. With the keyless locking/unlocking option (Passive Entry *),
the key can be anywhere in the car. 2. For cars with automatic gear changing, make
sure that gear position P or N is selected.
For cars with manual gear changing, make sure that the gear lever is in neutral positionand that either the clutch pedal or the brakepedal is depressed.
3. Depress the brake pedal fully 1
.
4. Turn the start knob to START and release it.
The control automatically returns to its star-ting position.
NOTE
For diesel-engined cars, there may be a slight delay before starting is initiated.
When the engine is started the starter motor works until the engine is started or until its over-heating protection triggers.

If the message
Car key not found is shown in
the driver display when starting, place the remote control key on the backup reader in the cupholder. Then try to start again.
NOTE
When the remote control key is placed in the cup holder, make sure that no other car keys,metal objects or electronic apparatus (e.g.mobile phones, tablets, laptops or chargers)are in the cup holder. Several car keys closeto each other in the cup holder can causeinterference with each other.
IMPORTANT
If the engine fails to start after 3 attempts - wait for 3 minutes before making a furtherattempt. Starting capacity increases if the bat-tery is allowed to recover.
WARNING
Never remove the remote control key from
the car while driving or during towing.
WARNING
Always take the remote control key out from the car when leaving the car and make surethe car's electrical system is in ignition posi- tion 0 - especially if there are children in the
car.
NOTE
The idling speed can be noticeably higher than normal for certain engine types duringcold starting. This is done in order that theemissions system can reach normal operatingtemperature as quickly as possible, whichminimises exhaust emissions and protects theenvironment.

Using jump starting with another battery
If the starter battery is discharged then the car can be started with current from another battery.
When jump starting the car, the following steps are recommended to avoid short circuits or otherdamage:
1. Set the car's electrical system in ignition position 0.
2. Check that the donor battery has a voltage of 12 V.
3. If the donor battery is installed in another car - switch off the donor car's engine and make sure that the two cars do not touch eachother. 4. Connect one of the red jump lead's clamps
to the donor battery's positive terminal (1).
IMPORTANT
Connect the start cable carefully to avoid short circuits with other components in theengine compartment.
5. Open the positive jump-starting point's cover(2).
6. Connect the red jump lead's other clamp onto the car's positive jump-starting point (2).
7. Connect one of the black jump lead's clamps to the donor battery's negative terminal (3).
8. Connect the black jump lead's other clamp onto the car's negative jump-starting point(4).
9. Check that the jump lead clamps are affixed securely so that there are no sparks duringthe starting attempt.
10. Start the engine of the "donor car" and allow it to run a few minutes at a speed slightlyhigher than idle approx. 1500 rpm.

11. Start the engine in the car with the dis-
charged battery.
IMPORTANT
Do not touch the connections between cable and car during the starting attempt. There is arisk of sparks forming.
12. Remove the jump leads in reverse order -first the black and then the red. Make sure that none of the black jump lead's clamps comes into contact with the car'spositive jump-starting point/donor battery'spositive terminal or the clamp connected tothe red jump lead.
WARNING
• The battery can generate oxyhydrogen gas, which is highly explosive. A spark canbe formed if a jump lead is connectedincorrectly, and this can be enough forthe battery to explode.
• The battery contains sulphuric acid, whichcan cause serious burns.
• If sulphuric acid comes into contact witheyes, skin or clothing, flush with largequantities of water. If acid splashes intothe eyes - seek medical attention imme-diately.

Gearbox
The gearbox is part of the car's driveline (power transmission) between engine and drive wheels.The function of the gearbox is to change thegear ratio depending on speed and powerrequirements.
There are two main types of gearbox, manual and automatic. The manual gearbox has six gears. The automatic gearbox can have either eight gears or six gearsdepending on which engine the car is equippedwith. The number of gear changes means thatthe engine's torque and power range can beused effectively. It is also possible to select gears manually with the automatic gearbox. The driver display respec-tively shows which gear or gear position is cur-rently in use.
IMPORTANT
To prevent damage to any drive system com- ponents, the working temperature of thegearbox is checked. If there is a risk of over-heating, a warning symbol illuminates in thedriver display and a text message is shown -follow the recommendation given.
Symbols in the driver displayIf a fault should occur in the gearbox, the driver display shows a symbol and a message.

Gear positions for automatic gearbox
With an automatic gearbox, the system chooses the gear so that driving is optimal. The gearboxalso has a manual gearshift mode.
Gear positions in the driver display
The driver display shows the gear selector's posi- tion:
P, R, N, D or M.
In manual gearshift mode, the gear being used is also shown.
Gear positions
Park position - P
Select the P position when the car is parked or
when starting the engine. The car must be sta- tionary when the park position is selected. To be able to move the gear selector from thepark position, the brake pedal must be depressed and the ignition position must be
II.
The gearbox is mechanically blocked when the P
position is engaged. Apply the parking brake first when the car is parked.
WARNING
Always use the parking brake when parking on an inclined surface. Engaging a gear or the automatic transmission's P position is not suf-
ficient to hold the car stationary in all situa- tions.
NOTE
The gear selector must be in P position to
allow the car to be locked and alarmed.
Reverse position - R
Select position R to reverse. The car must be sta-
tionary when reverse position is selected.
Neutral position - N
No gear is engaged and the engine can be started. Apply the parking brake if the car is sta- tionary with the gear selector in N position.
To be able to change from the neutral position to another gear position, the brake pedal must be depressed and the ignition position must be II.

STARTING AND DRIVING
* Option/accessory.391
Drive position - D
D is the normal driving position. Shifting up and
down takes place automatically based on the level of acceleration and speed. The car must be stationary when changing gear from R position to
D position.
Manual gearshift mode - M
The manual gearshift mode can be selected at any time while driving. The car engine-brakeswhen the accelerator pedal is released. Select manual gearshift mode by moving the gear selector sideways from position D to the
end position at " ±". The driver display shows
which gear is engaged at the time.
• Press the gear selector forwards to "
+"
(plus) to change up one step and release it.
• Press the gear selector backwards to "
–"
(minus) to change down one step and release it.
manual gearshift mode in the driver display 2
.
The gearbox automatically shifts down if the speed decreases to a level lower than appropri-ate for the selected gear, in order to avoid jerkingand stalling. To return to automatic gear changing, press the gear selector sideways to the end position at D.
Kick-downWhen the accelerator pedal is pressed all the way to the floor (beyond the position normallyregarded as full acceleration) a lower gear isimmediately engaged. This is known as kick-down. If the accelerator is released from the kick-down position, the gearbox automatically changes up. Kick-down is used when maximum accelerationis needed, such as for overtaking.
Safety function
To prevent over-revving of the engine, the gear- box control program has a protective downshiftinhibitor. The gearbox does not permit downshifting/kick- down which would result in an engine speed highenough to damage the engine. Nothing happensif the driver still tries to shift down in this way athigh engine speed – the original gear remainsengaged. When kick-down is activated the car can change one or more gears at a time depending onengine speed. The car changes up when theengine reaches its maximum speed in order toprevent damage to the engine.

Gear selector inhibitorThe gear selector inhibitor prevents accidental changing between different gear positions in anautomatic gearbox.
There are two different types of gear selector inhibitor - mechanical and automatic.
Mechanical gear selector inhibitor
The gear selector can be moved forward and back freely between N and D. Other positions are
locked with a latch that is released with the inhib- itor button on the gear selector. With the inhibitor button depressed the lever can be moved forwards or backwards between P, R ,
N and D.
Automatic gear selector inhibitorThe automatic gear selector inhibitor has special safety systems.
From park position - P
To be able to move the gear selector from the P
position, the brake pedal must be depressed and the ignition position must be II.
From neutral position - N
If the gear selector is in the N position and the
car has been stationary for at least 3 seconds (irrespective of whether the engine is running)then the gear selector is locked. To be able to move the gear selector from the N
position to another gear position, the brake pedal must be depressed and the ignition position must be II.
Deactivate automatic gear selector
inhibitor
If the car cannot be driven, e.g. due to a dis- charged battery, the gear selector must be moved to the
N position so that the car can be
moved.
Lift the rubber mat in the compartment in front of the gear selector. Locate the holewith a spring-loaded button in the bottom ofthe compartment.
Press a small screwdriver into the hole and hold.
Move the gear selector to position N and
release the button.
4. Put the rubber mat back in place.
