Economical driving
A more economical driving style can help lower fuel consumption.
Before driving
If possible, precondition the vehicle before driving.
If preconditioning is not possible when itis cold outside, use seat and steeringwheel heating first. Avoid heating theentire passenger compartment to reducethe amount of current being taken fromthe start battery.
Avoid using idling to warm up the vehiclebefore driving.
The type of tires and inflation pressureused could affect energy consumption –consult an authorized Volvo retailer foradvice on suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
While driving
Activate Eco drive mode.
Use gear selector position
D as often as
possible.
When using manual gear shifting, drive using the highest possible gear. Use the gear indicator 14
.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking. Use engine braking if possi-ble.
Higher speeds increase energy consump-tion because air resistance increases withspeed.
In a cold climate, reduce heating of thewindshield/rear window, mirrors, seatsand the steering wheel.
Avoid driving with the windows open.
Do not use the accelerator pedal to keepthe vehicle stationary on an uphill gradi-ent. Instead, activate the auto-hold brakefunction at a standstill.
Use trip data to see current fuel consump-tion.
WARNING
Never turn off the engine while the vehicle is moving, e.g. when driving downhill. Thisdeactivates certain important systemssuch as power steering and brakes.
After driving
If possible, park in a climate-controlled garage.

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.

Trailer Stability Assist *
Trailer Stability Assist (TSA 18
) is part of the
ESC 19
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. When Trailer Stability Assistis activated, the ESC symbolis displayed in the instrumentpanel.
NOTE
A vehicle software update is required when a towbar is retrofitted. Contact a Volvoretailer.

This section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applica- ble speed limit regulations.
Preparations and towing
CAUTION
For some transmission variants, it is not possible to shift from P position if theengine is switched off. Contact an author-ized Volvo workshop for assistance towingor call a professional towing service.
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
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.
