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 full pressure.
• 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 safe stop (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%.

STARTING AND DRIVING
358If
Vehicle key not found is displayed in the
instrument panel, place the remote key in the back-up reader in the tunnel console (see theillustration) and try again to start the engine.
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.
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.

Loading modeUse the buttons in the cargo compartment to raise or lower the vehicle to make loading orunloading easier or when attaching a trailer.
Parking the vehicleWhen parking, be sure that there is adequatespace above and below the vehicle since itsground clearance may vary, e.g., depending onthe ambient temperature, how the vehicle is loa-ded, if loading mode is being used or the drivemode selected after the engine is started. The level may also be adjusted for a certain time after the vehicle has been parked to compensatefor possible height adjustments due to tempera-ture changes in the pneumatic suspension whenthe vehicle has cooled.
TransportWhen transporting the vehicle on a ferry, train ora tow truck, it may only be secured (lashed)around the tires, not using any other chassiscomponents. Changes in the pneumatic suspen-sion may occur during transport that could nega-tively affect the lashing and result in damage.

MAINTENANCE AND SERVICING
498
Support battery Vehicles equipped with Start/Stop are equipped with two 12-volt batteries.
In addition to a heavy-duty start battery, models with Start/Stop also have a support battery thatprovides extra current during the Start/Stopfunction's start sequence.
The support battery is located in a box next to the spring strut in the engine compartment
The following table shows the specifications for the support battery:
Current (V)12
Cold start capacity (Cold Cranking Amperes -CCA) (A)170
Dimensions, L×W×H in. (mm)5.9×3.5×5.1
(150×90×130)
Capacity (Ah)10
• When replacing the start battery or support battery in a vehicle with Start/Stop, anAbsorbed Glass Mat (AGM) must be used.
• The greater the current consumption in thevehicle, the more the generator has to oper-ate and the battery is charged. This increasesfuel consumption.
• When the start battery's charge is below theminimum permitted level, the Start/Stopfunction will be disabled.
When the Start/Stop function is temporarily disa- bled due to high current consumption:
• The engine will auto-start, even if the brake pedal is depressed.
The support battery does not normally required more service than the start battery. If questionsarise, consult a Volvo retailer or trained and quali-fied Volvo service technician.
CAUTION
When connecting an external start battery or a battery charger, the Start/Stop function maybe temporarily disabled if the negative termi-nal on the vehicle's start battery is used toconnect an external start battery or a battery charger. Only the negative connection point
in the engine compartment may be used as a ground point.
NOTE
If the start battery is completely discharged and the vehicle has no normal electrical func-tions, and the engine is then started using anauxiliary battery or battery charger, theStart/Stop function will be activated. Theengine can then be auto-stopped but may notauto-start again due to an insufficient chargelevel in the start battery. To help ensure auto-start, the start battery should be charged first. At a temperature ofapprox. 60 °F (15 °C), the battery should becharged for at least 1 hour, preferably usingan external battery charger. At lower tempera-tures, the battery should be charged for3–4 hours. If a charger is not available, it is advisable to disable the Start/Stop function until the bat-tery is sufficiently recharged.
