Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to help stabilize a vehicle that is towing a trailerwhen the vehicle and trailer have begun to swayand is part of the Electronic Stability Control sys-tem.
FunctionA vehicle towing a trailer may begin to sway for various reasons. Normally this only occurs at highspeeds but, for example, if the trailer is overloa-ded or if the load is unevenly distributed in thetrailer, there is risk of swaying. Swaying may be caused by factors such as:
• The vehicle and trailer are hit by a sudden, strong crosswind
• The vehicle and trailer are traveling on anuneven road surface or drive over a bump
• Sudden movements of the steering wheel
Facts about TSA
• The stability system symbol in the instrumentpanel will flash when TSA is working
• If the driver switches off the stability system'sSpin Control function, TSA will also beswitched off (but will be on again the nexttime the engine is started)
• TSA may not intervene when the vehicle andtrailer begin to sway if the driver tries to com-pensate for the swaying motion by movingthe steering wheel rapidly

Battery drain Your vehicle's electrical functions drain the bat- tery to varying extents.
Avoid using ignition mode II as much as posssi-
ble, or electrical functions that require a great deal of electrical current when the engine is notrunning. Using ignition mode I whenever possible con-
sumes less electrical current. Functions that require a great deal of electrical current include:
• the climate system blower
• headlights
• wipers
• infotainment system (especially at high vol-ume).
If the battery's charge level is low, a text messagewill appear in the instrument panel. The vehicle'senergy-saving function will then turn off orreduce certain functions that are currently con-suming electrical current. If the battery needs to be recharged, start the engine and let it idle for at least 15 minutes ordrive the vehicle (driving charges the batteryfaster than letting the engine idle).

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.

Available drive modes
COMFORT
This is the default mode. When the engine is started, COMFORT drive mode will be selected and the Start/Stop func-tion will be activated. This setting offers drivingcomfort, light steering and relatively soft suspen-sion.
ECO
ECO drive mode is designed to help promote fuel-efficient driving. In this mode, Start/Stop is activated, ground clearance is lowered to help reduce wind resis-tance and certain climate system functions willbe reduced. There is an ECO gauge in the instrument panel to indicate the current level of fuel-efficiency. Seealso the article "ECO drive mode."
OFF ROAD
This mode helps maximize the vehicle's capacity to traverse difficult terrain or poor roads. In OFF ROAD, ground clearance is maximized, the steering is light, and All Wheel Drive and Hill Descent Control are activated.
Start/Stop is
deactivated. This drive mode can only be activated at low speeds (the permissible speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and anotherdrive mode will be activated. In OFF ROAD mode, a compass will be displayed in the instrument panel. This drive mode is not intended for normal street driving.
CAUTION
OFF ROAD drive mode may not be used if the vehicle is towing a trailer without an elec-trical connection. This could result in damageto the pneumatic suspension system's bel-lows.
Due to the increased ground clearance, if the OFF ROAD mode was selected when the enginewas switched off, the suspension will lower whenthe engine is restarted.

DYNAMIC
Dynamic drive mode is designed to provide
sportier driving characteristics. Gear shifting will be faster and more distinct and will occur athigher rpm. Steering response will be more immediate, the suspension will be stiffer and low ground clear-ance will help reduce body roll when cornering.
Start/Stop will be deactivated.
INDIVIDUAL
This setting allows you to adapt a drive mode to your personal preferences. Select one of the other drive modes as a basis and change the settings to provide the drivingcharacteristics that you prefer. These settings willbe stored in a driver profile.
