Jump starting using another battery If the start battery is discharged, current from another battery can be used to start the vehi-cle.
Jumper cable connecting points. Engine compart- ment appearance may vary depending on vehiclemodel and equipment level.
To avoid short circuits or other damage, the following steps are recommended when jumpstarting the battery using another battery:
1. Put the ignition in mode 0.
2. Make sure the auxiliary battery (the bat- tery used to jump start the discharged battery) has a voltage of 12 volts. 3. If the auxiliary battery is in another vehicle,
turn off that vehicle's engine and makesure that the vehicles are not touchingeach other.
4. Clamp the red jumper cable onto the auxil- iary battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to pre- vent short circuits with other componentsin the engine compartment.
5. Fold back the cover over your vehicle'spositive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start terminal (2).
7. Clamp the black jumper cable onto the auxiliary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securely attached to help prevent sparks whilejump starting. 10. Start the engine of the assisting vehicle
and let it run for a few minutes at a higheridling speed than normal, about1500 rpm.
11. Start the engine of the vehicle with the dead battery.
CAUTION
Do not touch the connections between the cable and the vehicle during the startattempt. Risk of sparking.
12. Remove the jumper cables in the reverseorder ‒ first the black cables and then the
red cables. Make sure that none of the clamps of the black jumper cables come into contactwith either vehicle's positive (+) jump startterminals or either of the red jumpercable's connected clamps.

WARNING
High voltage may be dangerous if handled incorrectly. Do not touch anything on bat-teries that is not clearly described in thisOwner's Manual. Never use a 48 V support battery to jump start the vehicle.
External electrical equipment may notunder any circumstance be connectedto the 48 V battery.
Only a workshop may replace or per-form service on the 48 V battery – anauthorized Volvo workshop is recom-mended.
WARNING
PROPOSITION 65 WARNING!
Battery
posts, terminals, and related accessories contain lead and lead compounds, chemi-cals known to the state of California tocause cancer and reproductive harm. Washhands after handling.
WARNING
Batteries generate hydrogen gas, which is flammable and explosive.
Do not connect the jumper cable toany part of the fuel system or to anymoving parts. Avoid touching hotmanifolds.
Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces.
If contact occurs, flush the affectedarea immediately with water. Obtainmedical help immediately if eyes areaffected.
Never expose the battery to open flameor electric spark. Do not smoke nearthe battery. Failure to follow theinstructions for jump starting can leadto injury.
NOTE
If the starter battery has been discharged to the extent that the vehicle does not havenormal electrical functions and the enginemust then be jump-started with an externalbattery or a battery charger, the Start/Stopfunction may remain activated. If the Start/Stop function shortly thereafter auto-stopsthe engine, there is a huge risk that auto-start of the engine will fail due to insuffi-cient battery capacity since the battery hadnot had time to recharge. If the vehicle has been jump-started or if there has not been enough time for thebattery to be charged with a batterycharger, the Start/Stop function should betemporarily deactivated until the batteryhas been recharged by the vehicle. At anambient temperature of about +15°C(about 60°F), the battery must be chargedby the vehicle for at least one hour. Atlower ambient temperatures, the chargingtime can increase to 3-4 hours. It is advisa-ble to charge the battery with an externalbattery charger.

Driving with a trailer
There are a number of things to consider when towing a trailer, such as the towbar, thetrailer and how the load is distributed in thetrailer.
Load-carrying capacity is determined by the vehicle's curb weight. The total weight of allpassengers and any installed accessories, e.g.towbar, reduces the vehicle's load-carryingcapacity by the corresponding amount.
Towbars used on the vehicle must beapproved for the applicable use.
Distribute the load on the trailer so thatthe weight on the towbar complies withthe specified maximum towball weight.The tongue weight is calculated as part ofthe vehicle's payload.
Increase the tire pressure to the recom-mended pressure for a full load.
The engine is subjected to more load thanusual when towing a trailer.
Towing a trailer affects the vehicle's han-dling, durability and driving economy.
Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
On long and steep downgrades, the vehi-cle's brakes are subjected to much moreload than usual. When manually shifting, downshift and adapt speed accordingly.
Follow applicable regulations regarding permitted speed and weight.
Drive slowly when towing a trailer up along and steep incline.
The maximum trailer weights given onlyapply to altitudes up to 1000 meters(3280 feet) above sea level. At higher alti-tudes, engine power (and thus the vehi-cle's climbing ability) is decreased due tothe reduced air density, and the maximumtrailer weight must therefore be reduced.The weight of the vehicle and trailer mustbe decreased by 10% for each additional1000 m (3280 feet) or part thereof.
Avoid driving with a trailer on inclines ofmore than 12%.
Avoid overloading and other incorrect use.
The trailer's brakes must be balanced withthe vehicle's brakes to help ensure safestops (follow applicable local regulations).

CAUTION
Bumper-attached trailer hitches must not be used on Volvos, nor shouldsafety chains be attached to thebumper.
Trailer hitches attaching to the vehiclerear axle must not be used.
Never connect a trailer's hydraulicbrake system directly to the vehiclebrake system, nor a trailer's lightingsystem directly to the vehicle lightingsystem. Consult your nearest author-ized Volvo retailer for correct installa-tion.
When towing a trailer, the trailer'ssafety chains or wire must be correctlyfastened to the attachment points pro-vided in the trailer hitch on the vehicle.The safety chain or wire must never befastened to or wound around the tow-ing ball.
NOTE
The optional detachable trailer hitch may not be available in all markets or on allmodels. Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer, high altitude and lower fuel gradethan recommended are factors that cansignificantly increase the vehicle's fuel con-sumption.
Trailer weights
WARNING
Please adhere to the recommendations provided for trailer weight. If the recom-mendations are not followed, the vehicleand trailer may be difficult to control duringevasive maneuvers and braking.
NOTE
The specified maximum trailer weights are those permitted by Volvo. National vehicleregulations may set additional restrictionson trailer weight and speed. The trailerhitches may be certified for higher towingweights than the vehicle is permitted totow.
Self-leveling suspension
*The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardlessof load (up to the maximum permitted weight).When the vehicle is stationary, the rear end of the vehicle will be slightly lowered, which isnormal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of over-heating when driving with a trailer. If overheat-ing of the engine and drive system is detected,a warning symbol will illuminate in the instru-ment panel and a message will appear. The automatic transmission adapts the gear for the current load and engine speed.
Steep inclines
Do not lock the automatic transmission into a higher gear than what the engine can handle
‒
it is not always preferable to drive in highgears at low rpm.
Parking on a hill
1. Depress the brake pedal.
2. Apply the parking brake.
3. Put the gear selector in P.
4. Release the brake pedal.Put chocks behind the wheels when the vehi- cle is parked on a hill with a trailer attached.
Starting on a hill
1. Depress the brake pedal.

Trailer Stability Assist (TSA 23
) is part of the
ESC 24
stability system and is a function
designed to help stabilize a vehicle that is towing a trailer when the vehicle and trailerhave begun to sway. The function is addedwhen installing a towbar. Contact a Volvoretailer for more information.
Reasons for swayingA vehicle towing a trailer may begin to sway for various reasons. Normally this only occursat high speeds. However, if the trailer is over-loaded or unevenly distributed, e.g. too farback, there is a risk of swaying even at lowspeeds. 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 or over a bump.
Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult orimpossible to stop it. This makes the vehicleand trailer difficult to control and there is a riskof swerving into oncoming traffic or driving offthe road.
Trailer Stability Assist functionTrailer Stability Assist continuously monitorsthe vehicle's movements, particularly lateralmovements. If swaying is detected, the brakesare applied individually on the front wheels,which has a stabilizing effect on the vehicleand trailer. This is often enough to enable thedriver to regain control of the vehicle. If the Trailer Stability Assist function's first attempt is not adequate to stop the swayingmotion, the brakes are applied on all wheelsand engine power is temporarily reduced. Asthe swaying motion begins to decrease andthe vehicle and trailer have once againbecome stable, TSA stops regulating thebrakes/engine power and the driver regainscontrol of the vehicle.
NOTE
Trailer Stability Assist is deactivated if the driver activates ESC Sport Mode in the
center display's menu system.
Trailer Stability Assist may not intervene if the driver tries to compensate for the swayingmotion by moving the steering wheel rapidly,because the system will then not be able todetermine if it is the trailer or the driver caus-ing the swaying.

WARNING
Ignition mode
II must be active – all
airbags are deactivated in ignition mode I.
Always have the remote key in thevehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much moreeffort than normal.
1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.
3. Put the vehicle in ignition mode II – with-
out pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral (N) and release the parking brake. If the battery charge level is too low, it may not be possible to release the parkingbrake. Connect an auxiliary battery to thevehicle if the battery is discharged.
> The towing vehicle can now start driv-ing. 5. Keep the towline taut when the towing
vehicle slows down by applying light pres- sure to the brake pedal. This will helpavoid jarring movements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Usean auxiliary battery if the start battery's chargelevel is so low that the engine cannot bestarted.
CAUTION
Attempting to tow with the engine running could result in damage to the three-waycatalytic converter.
