Deactivation of the Auto-hold brake function
In certain situations, auto-hold will be deacti- vated when the vehicle is at a standstill andthe function will go into standby mode. Thismeans that the brakes will be released and thevehicle could begin to roll. The driver mustactively apply the brakes to keep the vehiclestationary. This can occur if:
the driver depresses the brake pedal
the parking brake is applied
the gear selector is moved to the
P, N or R
positions
the driver puts the function in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will beapplied to keep the vehicle at a standstill. This occurs if the function is keeping the vehi- cle stationary using the brakes and:
the driver opens the door or unbuckleshis/her seat belt
the function has kept the vehicle at astandstill for more than approx. 5 minutes
the brakes overheat
the driver switches off the engine man-ually.

Braking assist after a collision
In a collision in which the activation level is reached for the pyrotechnic seat belt tension-ers or airbags, or if a collision with a large ani-mal is detected, the vehicle's brakes will beautomatically activated. This function isintended to help prevent or reduce the effectsof any subsequent collision.
After a serious collision, it may no longer be possible to control and steer the vehicle. Inorder to avoid or mitigate a possible furthercollision with a vehicle or an object in the vehi-cle's path, the brake assist system is activatedautomatically to help stop the vehicle safely. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the drivercan override the system by depressing theaccelerator pedal. This function assumes that the brake system is intact after a collision.

Transmission
The transmission is part of the vehicle's drive- line (power transmission) between the engineand the drive wheels. The function of thetransmission is to change gears dependingon speed and power needs.
The vehicle has an 8-speed automatic trans- mission. The number of gears allows theengine's torque and power band to be effec-tively utilized. Two of the gears are overdrivegears that save fuel when driving at a constantengine speed. Manual shifting is also possible.The instrument panel shows the gear currentlyin use.

Automatic transmission
In vehicles with an automatic transmission, the system selects the gear so that drivingwill be as energy-efficient as possible. Thetransmission also has a manual mode.
The transmission is available in different ver- sions. The gear selector indicates which trans-mission the vehicle has. The various gearselectors have different functions.

All Wheel Drive (AWD) *
All-wheel drive (AWD 8
), also called four-
wheel drive, means that power is distributed to all four wheels, which improves traction.
To achieve the best traction, power is auto- matically directed to the wheels that have thebest grip. The system continuously calculatesthe need for torque to the rear wheels, andcan immediately redistribute up to half of theengine's torque to the rear wheels. All-wheel drive also has a stabilizing effect at higher speeds. In normal driving conditions,most of the engine's power is directed to thefront wheels. When the vehicle is stationary,all-wheel drive is always activated in prepara-tion for maximum traction during acceleration. All-wheel drive reacts differently depending on which drive mode is selected.

Eco drive mode
Eco drive mode can help make driving more
fuel-efficient and eco-friendly.
Use this mode to save fuel and promote eco- friendly driving. When
Eco mode is activated, the following
characteristics are modified:
The automatic transmission's shifting points.
Engine control and accelerator pedalresponse.
Eco Coast functionality is activated andengine braking is disabled when the accel-erator pedal is released at speedsbetween 65 and 140 km/h(40 and 87 mph).
Some of the climate system settings willbe reduced or switched off.
Information will be shown in the ECOgauge in the instrument panel to help pro-mote more eco-friendly and economicaldriving.
Coast function Eco CoastEco Coast essentially deactivates engine brak-ing, allowing the vehicle's kinetic energy to beused to roll greater distances. When the driverreleases the accelerator pedal, the transmis-sion is automatically disengaged from theengine. Engine speed is reduced to idlingspeed to reduce fuel consumption.

402 This function is most effective in driving situa- tions where the vehicle can roll freely for along distance, e.g. on roads with slight down-grades or when a decrease in speed is antici-pated, such as when approaching an area witha lower speed limit.
Activating Eco Coast
The function is activated when the accelerator pedal is fully released and the following condi-tions are met:
Eco drive mode is activated.
The gear selector is in
D.
The vehicle's speed is approximately 65-140 km/h (40-87 mph).
The gradient of the downgrade is less thanapproximately 6%.
COASTING will be displayed in the instrument
panel when Eco Coast is being used.
Limitations
Eco Coast is not available if
the engine and/or transmission are not at normal working temperatures
the gear selector is moved from
D to man-
ual shifting mode
the vehicle's speed is not within the65-140 km/h (40-87 mph) range
the gradient of the downgrade is morethan approximately 6%
The steering wheel paddles
* are being
used for manual shifting.
Deactivating and turning off Eco Coast
In certain situations, it may be advisable to deactivate or turn off Eco Coast so that enginebraking can be used. These situations mightinclude driving down steep hills or beforepassing another vehicle to help ensure thiscan be done as safely as possible. Deactivate Eco Coast by
pressing the accelerator or brake pedal
moving the gear selector to manual mode
Using the steering wheel paddles

view.
It is possible to roll short distances even with- out Eco Coast in order to help conserve fuel.However, for the best fuel economy, EcoCoast should be activated and used to rolllonger distances.
Cruise control Eco CruiseWhen cruise control is activated in the Ecodrive mode, the vehicle's acceleration and deceleration will be slower than in other drivemodes to help further conserve fuel. Becauseof this, the vehicle's actual speed may beslightly above or below the set speed.
On a level road, the vehicle's actual speedmay differ from the set speed when cruisecontrol is active and the vehicle is coast-ing.
On a steep uphill gradient, the vehicle'sspeed is reduced until the transmissiondownshifts. Reduced acceleration is theninitiated in order to reach the set speed.
On a downhill gradient in which the vehi-cle is coasting, the vehicle's actual speedmay be slightly above or below the setspeed. The function uses engine brakingto keep the set speed. If necessary, thenormal brakes are also applied.

Economical driving
Drive economically and more environmentally conscious by thinking ahead and avoidingrapid starts and stops.
Adapt your driving style and speed to the cur- rent traffic conditions. Observe the following rules:
For lower fuel consumption, activate
Ecodrive mode.
Use the Eco Coast function in drive mode
Eco - engine braking is deactivated, allow-
ing the vehicle's kinetic energy to be used to roll greater distances.
Use gear
D as often as possible and avoid
using the kick-down function.
For manual gear shifting, use the highestpossible gear for the current traffic situa-tion and road conditions - fuel consump-tion is reduced at lower engine speeds (rpm). Use the gear indicator 13
.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking.
Fuel consumption is increased at highspeeds - air resistance increases withspeed.
The trip computer's current fuel consump-tion indicator can help promote more fuel-efficient driving.
Do not warm up the engine by idling. It isbetter to begin driving normally immedi-ately after starting the engine. A coldengine uses more fuel than a warmengine.
Whenever possible, avoid using the vehi-cle to drive short distances. The enginedoes not have time to reach a normaloperating temperature and this leads toincreased fuel consumption.
Use engine braking to brake the vehicle,when this is safe for other road users.
Maintain the correct pressure in the tiresand check pressure regularly.
The type of tires used could affect fuelconsumption - consult a retailer for adviceon suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
