Shiftlock The automatic transmission's shiftlock function helps prevent inadvertently moving the gearselector between different positions.
There are two types of shiftlocks: mechanical and automatic.
Mechanical shiftlock
The gear selector can be moved back and forth between N and D. The other positions have a
shiftlock that is operated using the lock button on the gear selector. Press and hold the shiftlock button and move the gear selector forward or backward between P, R ,
N and D.
Automatic shiftlockThe automatic shiftlock has a separate safety system.
From Park - P
To move the gear selector from the P position,
the brake pedal must be depressed and the igni- tion in mode II.
From Neutral - N
If the gear selector is in N and the vehicle has
been stationary for at least 3 seconds (with or without the engine running), the gear selector willbe locked in that position. To move the gear selector from N to another
gear, the brake pedal must be depressed and the ignition in mode II.

Deactivating the automatic shiftlock
The automatic shiftlock can still be disengaged even when there is no electrical current to thevehicle.
Deactivating the automatic shiftlock
If the vehicle cannot be driven (e.g. due to a dis- charged battery), the gear selector must be moved to the N position so that the vehicle can
be moved.
Lift the rubber mat in the storage compart- ment in front of the gear selector. Locate thehole with a spring-loaded button in the bot-tom of the compartment.
Press a small screwdriver or similar object into the hole and hold it down.
Move the gear selector to N and release the
button.
4. Replace the rubber mat.

The kickdown function
Kickdown is used when maximum acceleration is needed, e.g. when passing.
When the accelerator pedal is depressed all the way to the floor (past the normal full acceleratorposition), the transmission will automaticallyengage kickdown, i.e. immediately shift down to alower gear. If the accelerator pedal is released from the kick- down position, the transmission will automaticallyshift up again.
Safety function
The transmission control module is equipped with a downshift protection feature to help prevent theengine from overheating. In some conditions, the transmission will prevent downshifting/kickdown if this would lead to suchhigh engine speed (rpm) that the engine couldbe damaged. If the driver still attempts downshift-ing or kickdown at a high rpm, nothing will hap-pen and the original gear will remain selected. With kickdown, the vehicle can downshift one or more steps at a time depending on the enginespeed. The vehicle upshifts when the engine rea-ches its maximum rpm to prevent engine dam-age.

Gear indicator
*
The gear indicator in the instrument panel shows the gear currently being used for manual shiftingand indicates when another gear should beselected to optimize fuel economy.
For eco-friendly driving when manually shifting, it is important to use the correct gear and to shiftgears in good time. The gear indicator in the instrument panel shows the gear currently being used and indicates withan upward-facing arrow if a higher gear shouldbe selected.

All Wheel Drive (AWD)
*
All-wheel drive, All Wheel Drive (AWD), also called four-wheel drive, means that power is dis-tributed to all four wheels, which improves trac-tion.
To achieve the best traction, power is automati- cally directed to the wheels that have the bestgrip. The system continuously calculates theneed for torque to the rear wheels, and canimmediately redistribute up to half of the engine'storque to the rear wheels. All-wheel drive also has a stabilizing effect at higher speeds. In normal driving conditions, mostof the engine's power is directed to the frontwheels. When the vehicle is stationary, all-wheeldrive is always activated in preparation for maxi-mum traction during acceleration. All-wheel drive reacts differently depending on which drive mode * is selected.

Drive modes
*
Drive modes affect the vehicle's driving charac- teristics in different ways to enhance and sim-plify the driving experience in certain types of sit-uations.
Drive modes enable easy access to the vehicle's many functions and settings in different drivingsituations. The following systems are adapted tohelp optimize driving characteristics in each drivemode: • Steering
• Engine/transmission/all-wheel drive
*
• Brakes
• Shock absorbers
• Instrument panel
• Start/Stop function
• Climate control settings
Select the drive mode that is best suited to the current driving conditions. Keep in mind that notall drive modes are available in all situations.
Available drive modes
COMFORT
• This is the vehicle's default mode.
When the engine is started, the vehicle will be in Comfort mode and the Start/Stop function will beactivated. This setting offers driving comfort, lightsteering and soft suspension.

ECO drive mode
The Eco drive mode optimizes the vehicle's driv- ing characteristics for more fuel-efficient andeco-friendly driving.
Use this mode to save fuel and promote eco- friendly driving. When ECO mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points.
• Engine control and accelerator pedalresponse.
• Eco Coast functionality is activated andengine braking is disabled when the acceler-ator pedal is released at speeds between65 and 140 km/h (40 and 87 mph).
• Some of the climate system settings will bereduced or switched off.
• Information will be shown in the ECO gaugein the instrument panel to help promotemore eco-friendly and economical driving.
Coast function Eco CoastEco Coast essentially deactivates engine braking,allowing the vehicle's kinetic energy to be used to roll greater distances. When the driver releases the accelerator pedal, the transmission is auto- matically disengaged from the engine. Enginespeed is reduced to idling speed to reduce fuelconsumption.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applicable speed limit regulations.
Preparations and towing
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
• Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
WARNING
•
Ignition mode
II must be active – all air-
bags are deactivated in ignition mode I.
• Always have the remote key in the vehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much more effortthan normal. 1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.3.
Put the vehicle in ignition mode II – without
pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral ( N) and
release the parking brake. If the battery charge level is too low, it may not be possible to release the parking brake.Connect an auxiliary battery to the vehicle ifthe battery is discharged.
> The towing vehicle can now start driving.
5. Keep the towline taut when the towing vehi- cle slows down by applying light pressure to the brake pedal. This will help avoid jarringmovements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.
