Driving with a trailer
When towing a trailer, always observe the legal requirements of the state/province.
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
• Increase tire pressure to recommended fullpressure.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
• If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy. •
It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
•
When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.

How TSA worksOnce swaying has begun, it can be very difficult to stop, which makes it difficult to control thevehicle and trailer. The TSA system continuously monitors the vehi- cle's movements, particularly lateral movement. Ifthe system detects a tendency to sway, thebrakes are applied individually on the frontwheels, which has a stabilizing effect on the vehi-cle and trailer. This is often enough to enable thedriver to regain control of the vehicle. If this is not adequate to stop the swaying motion, the brakes are applied to all of the wheels on thevehicle and on the trailer if it is equipped withbrakes, and engine power is temporarily reduced.As the swaying motion begins to decrease andthe vehicle-trailer have once again become sta-ble, TSA will now stop regulating the brakes/engine power and the driver regains control ofthe vehicle. TSA is deactivated if the driver deactivates
ESCin the center display's menu system.
When the ESC symbol in the
instrument panel flashes, TSA is active.

WARNING
•Never use more than one floor mat at a time on the driver's floor. Before driving,remove the original mat from the driver'sseat floor before using any other type offloor mat. Any mat used in this positionshould be securely and properly anchoredin the attaching pins. An extra mat on thedriver's floor can cause the acceleratorand/or brake pedal to catch. Check thatthe movement of these pedals is notimpeded.
• Volvo's floor mats are specially manufac-tured for your car. They must be firmlysecured in the clips on the floor so thatthey cannot slide and become trappedunder the pedals on the driver's side.
Back-up reader in the tunnel console
If Vehicle key not found is displayed in the
instrument panel, place the remote key in the back-up reader in the tunnel console (see the illustration) and try again to start the engine.
NOTE
When the remote key is in the back-up reader, be sure there are no other metallicobjects (e.g., other keys, coins, cell phones) inthe cup holder. This could affect the back-upreader's function.
CAUTION
If the engine does not start after the third try, wait for approximately 3 minutes before tryingto start it again to give the battery time torecover its starting capacity.
WARNING
•
Always remove the remote key from the passenger compartment when leaving thevehicle and ensure that the ignition in mode
0.
• On vehicles with the optional Passive Entry, 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 noticea- bly higher than normal for a short period. Thisis done to help bring components in theemission control system to their normal oper-ating temperature as quickly as possible,which enables them to control emissions andhelp reduce the vehicle's impact on the envi-ronment.

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. INDIVIDUAL is only available if it has been acti- vated in the center display.

ECO drive mode
The Eco drive mode is a function designed to give the driver the opportunity to drive more eco-nomically and to help reduce fuel consumption.
When this mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points
• The engine management system and accel-erator pedal response
• Eco Coast functionality is activated: enginebraking is disabled at speeds betweenapprox. 40 and 87 mph(65 and 140 km/h)
• Climate system settings: certain functionswill be temporarily reduced or deactivated
• The suspension's self-leveling function
* low-
ers ground clearance to help reduce windresistance
• Information is shown in an ECO gauge in theinstrument panel to help promote more eco-nomical driving
NOTE
When Eco is activated, several climate system parameters are changed and the function ofcertain current-consuming systems will bereduced. Some of these functions can be restarted manually but full functionality will not berestored until Eco is deactivated.
Selecting ECO modeWhen the engine is switched off, ECO mode is deactivated and must be reactivated each time the engine is started.
ECO will appear in the
instrument panel when the function is activated.

Eco CoastEco Coast essentially deactivates engine braking,allowing the vehicle to roll freely. When the driver releases the accelerator pedal, the transmission is automatically disengagedfrom the engine to allow the vehicle to roll as faras possible, which helps reduce fuel consump-tion. This feature is primarily intended to be used in driving situations where the vehicle can roll freely,such as down gentle hills or when a decrease inspeed is expected, such as when approaching anintersection or a traffic light. Eco Coast enables proactive driving with as little braking as possible. Depending on the driving situation, Eco and Eco Coast can be used in different ways to helpreduce fuel consumption: • With Eco activated
: this enables Eco Coast,
which allows the vehicle to roll freely for as
far as possible when the driver releases the
accelerator pedal (e.g., when approaching a traffic light or intersection).
or
• With Eco deactivated
: engine braking can
be used when the vehicle will only roll for

388 a short distance
(in heavy traffic, etc.) or
when driving down hills .
To help keep fuel consumption as low as possi- ble, Eco Coast should not be used in traffic situa-tions where the brakes have to be used fre-quently.
Activating Eco Coast
Eco Coast is activated when the accelerator pedal is released completely if:
• Eco is activated
• The gear selector is in
D
• The vehicle's speed is between approxi-mately 40 and 87 mph(65 and 140 km/h)Always observe posted speed limits
• The gradient of a down-slope is less thanapproximately 6%
COASTING will appear in the instrument panel
when Eco Coast is being used.
Limitations
Eco Coast is not available if:
• The engine and/or transmission have not reached their normal operating temperature
• Cruise control is activated
• The gear selector is moved from
D to " +/-"
for manual shifting
• The vehicle's speed is not within the40 and 87 mph(65 and 140 km/h) range •
The gradient of a down-slope is more thanapproximately 6%
• The steering wheel paddles
* are used for
manual shifting
Deactivating and turning off Eco Coast
In certain situations, it may be advisable to switch off the Eco Coast function, such as:
• When driving down steep hills, in order to uti-lize engine braking
• Prior to passing another vehicle, in order todo so as safely as possible
Deactivating Eco Coast (and reactivating enginebraking) can be done in the following ways: • Move the gear selector to the manual "
+/–"
position
• Change gears using the steering wheel pad- dles
*
• Press the brake or accelerator pedal
Turn the function off by changing drive modes * or
by turning ECO off in the center display's Func- tion view. The vehicle will roll for short distances even if Eco Coast is turned off to help conserve fuel.However, for the best fuel economy, the functionshould be used as much as possible.
