Location of the backup reader in the tunnel console.
NOTE
When the remote key is placed in the backup reader, make sure that no othervehicle keys, metal objects or electronicdevices (e.g. cellular phones, tablets, lap-tops or chargers) are in the backup reader.Multiple vehicle keys close to each other inthe backup reader can disrupt their func-tionality.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before star-ting a new attempt. Starting capabilityincreases if the starter battery is given timeto recover.
WARNING
Never remove the remote control key from
the vehicle while driving or the vehicle is being towed.
WARNING
Always remove the remote key from the passenger compartment when youleave the vehicle and make sure theignition is in mode
0.
Always put the gear selector in
P and
apply the parking brake before leavingthe vehicle. Never leave the vehicleunsupervised while the engine is run-ning.
Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by thevehicle contain carbon monoxide,which is invisible and odorless but verytoxic.
CAUTION
When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it hasreached the proper operating tempera-ture.
The engine should be idling when thegear selector is moved. Never acceler-ate until the gear is fully engaged.Accelerating rapidly before a gear isproperly engaged could lead to harderwear of components.
To help prevent the transmission oilfrom overheating, select
P or N when
idling at a standstill for prolonged peri-ods of time.

NOTE
With a cold start, idling speed may be con- siderably higher than normal for certainengine types. This is done to get the emis-sions system up to normal operating tem-perature as quickly as possible, which min-imizes exhaust emissions and protects theenvironment.

Brake functions
The vehicle's brakes are used to reduce speed or prevent the vehicle from rolling.
In addition to the wheel brakes and parking brakes, the vehicle is also equipped with anumber of automatic brake assist functions.These systems provide assistance by e.g. thedriver not needing to depress the brake pedalat a traffic light or when starting up a hill. Depending on how the vehicle is equipped, the following brake assist functions may beincluded:
Auto-hold brake function at a standstill(Auto Hold)
Hill Start Assist (Hill Start Assist)
Braking assist after a collision

Brakes
The brake pedal is used to apply the vehicle's regular brakes, which are part of the brakesystem.
The vehicle is equipped with two brake cir- cuits. If one brake circuit is damaged, thebrake pedal will go down further whendepressed. More pressure will then berequired from the driver for normal brakingeffect. The driver's pressure on the brake pedal is enhanced by a power braking function.
WARNING
Power braking only functions if the engine is running.
If the brake pedal is used when the engine is turned off, the pedal will feel stiffer than usualand greater pressure must be applied to brakethe vehicle. In very hilly areas or when driving with a heavy load, manual gear shifting can be used to aug-ment the brakes with engine braking. Enginebraking is most effective if the same gear isused both uphill and downhill.
Anti-lock brakesThe vehicle is equipped with an Anti-lock Braking System (ABS 2
), which helps prevent
the wheels from locking and helps maintain steering control when braking. Vibrations maybe felt from the brake pedal when ABS isoperating, which is normal. After the vehicle is started, a brief test of the ABS system is automatically performed whenthe driver releases the brake pedal. An addi-tional automatic test of the system may beperformed when the vehicle is traveling at alow speed. During the test, the brake pedalmay feel as though it is pulsating.Symbols in the instrument panel

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.
