BLIS* – Cross Traffic Alert (CTA)
Cross Traffic Alert (CTA) is a supplementary BLIS 15
function intended to detect vehicles
crossing behind your vehicle while you are back- ing up.
Park assist/CTA button
On vehicles equipped with the optional Park assist system (p. 231), Cross Traffic Alert (CTA)can be deactivated/reactivated by pressing thePark assist button on the center console. TheBLIS indicator lights on the front doors will flashwhen CTA is reactivated by pressing the button.
WARNING
• BLIS and CTA are information systems, NOT warning or safety systems and donot function in all situations.
• BLIS and CTA do not eliminate the needfor you to visually confirm the conditionsaround you, and the need for you to turnyour head and shoulders to make surethat you can safely change lanes or backup.
• As the driver, you have full responsibilityfor changing lanes/backing up in a safemanner.
When does CTA function
How CTA works
CTA supplements BLIS by warning the driver of crossing traffic behind your vehicle, for example,when backing out of a parking space. It is primarily designed to detect another vehicle but in certain cases may also detect pedestriansor smaller objects such as bicycles. CTA is only activated when the vehicle is backing up and is activated automatically when the gearselector is put in reverse.
• An audible signal indicates that CTA hasdetected something that is approaching fromthe side. The signal will come from either theleft or right audio system speakers, depend-ing on which the side of your vehicle theapproaching vehicle/object has beendetected.
• CTA also provides a warning by illuminatingthe BLIS indicator lights.
• An icon will also illuminate in the Park assistgraphic on the center console display.
LimitationsCTA has limitations in certain situations, forexample, the CTA sensors cannot "see" throughother parked vehicles or obstructions. The following are several examples where CTA's "field of vision" may initially be limited andapproaching vehicles cannot be detected untilthey are too close:

CTA's blind area
CTA's "field of vision"
In angled parking spaces, CTA may be "blind" on one side
However, as you back your vehicle out of a park- ing space, CTA's "field of vision" expands. Examples of other limitations include:
• Dirt, ice or snow obstructing the sensors mayreduce the system's function or make itimpossible to detect other vehicles orobjects.
• Do not attach tape, decals, etc., on the sur-face of the sensors (see the illustration in thefollowing "Maintenance" section).
• BLIS and CTA are deactivated if a trailer'swiring is connected to the vehicle's electricalsystem.

WARNING
•Always remove the remote key from the ignition slot when leaving the vehicle and ensure that the ignition in mode
0 (see
Ignition modes (p. 74) for information about the ignition modes).
• On vehicles with the optional keylessdrive, never remove the remote key fromthe vehicle while it is being driven ortowed.
• Always place the gear selector in Parkand apply the parking brake before leav-ing the vehicle. Never leave the vehicleunattended with the engine running.
• Always open garage doors fully beforestarting the engine inside a garage toensure adequate ventilation. The exhaustgases contain carbon monoxide, which isinvisible and odorless but very poisonous.
NOTE
•After a cold start, idle speed may be noticeably higher than normal for a shortperiod. This is done to help bring compo-nents in the emission control system totheir normal operating temperature asquickly as possible, which enables themto control emissions and help reduce the vehicle's impact on the environment 3
.
CAUTION
• When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
• Selecting
P or N when idling at a stand-
still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.

Engine Remote Start (ERS) * –
introduction
ERS is a feature that makes it possible to remotely start the engine using the remote key tocool or heat the passenger compartment beforedriving.
The climate system will start using automatic set- tings. When the engine is started using ERS, it will run for a maximum of 15 minutes before automati-cally switching off again. After 2 ERS starts, theengine must be started in the normal way beforeERS can be used again.
NOTE
• Always adhere to applicable State, Prov- ince and/or Local laws regarding engineidling when using ERS.
• The service life of the remote key's bat-tery is affected by ERS use. If this featureis used frequently, the battery should bereplaced once a year, see Remote key –replacing the battery (p. 151).
WARNING
Keep the following in mind before using ERS:
• The vehicle should be in view.
• The vehicle should be unoccupied.
• The vehicle must not be parked indoors or in an enclosed area. Exhaust fumes areharmful to the health.

• if the gear selector was in
S when the
paddles were activated
If the transmission reverts to D, the paddles
will have to be reactivated (pull either paddletoward the steering wheel and release it)before they can be used to shift gears again. The paddles can also be manually deactivated by pulling both paddles toward the steeringwheel and holding them until the gear num-ber shown in the instrument panel changes to D .
Geartronic : Sport mode ( S)7
This transmission mode provides sportier shifting characteristics and enables a more active drivingstyle by making it possible to drive at higher rpmin each gear before shifting up. The engine alsoresponds faster when the accelerator pedal ispressed. To access Sport mode from Drive (
D), move the
gear selector to the left. The transmission will not switch to manual shifting mode until the gearselector is moved forward or rearward toward +or –. Sport mode can be selected any time.
NOTE
• On vehicles equipped with Sport mode, the transmission symbol in the main instrument panel will change from
D to S
when the gear selector is moved to the manual shifting mode. If the gear selectoris moved toward "+" or "-", the number ofthe gear currently being used will be dis-played, see Information displays – intro-duction (p. 63).
• Please be aware that using Sport modemay result in a slight decrease in fuel economy. Driving in
D can help improve
fuel economy.

Start/Stop is activated automatically each time the engine is started 9
. The symbol in the instru-
ment panel will be displayed for several seconds when the engine starts and the indicator light inthe On/Off button will remain illuminated whilethe function is activated. All of the vehicle's systems will function while the engine is auto-stopped, although the function ofcertain systems may reduced at this time. Forexample, blower speed and high infotainmentsystem volume may be reduced to help conservethe battery's capacity.
Auto-stopping the engine
Normally, when Start/Stop is activated and the brakes are applied until the vehicle comes to a standstill, the engine will auto-stop automatically if the driver keeps the brake pedal depressed
.
To remind the driver that the enginehas been auto-stopped, the Start/Stopsymbol will illuminate in the instrumentpanel and remain on until the engine
restarts.
If the ECO function * is acti-
vated, the engine may auto- stop before the vehicle comesto a complete standstill.
Auto-starting the engine
The engine restarts as soon as the driver relea- ses the brake pedal.
Deactivating Start/Stop
In certain situations (e.g., driv- ing in heavy, stop-and-go traf-fic), it may be preferable todeactivate Start/Stop. This is done by pressing the button in the center console.
The indicator light in the button will go out. Start/Stop will remain deactivated until the but- ton is pressed again or until the engine isswitched off and restarted by the driver.
