Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driving longdistances.
Check that:
• the engine is running properly and that fuel consumption is normal
• there are no leaks (fuel, oil or other fluid)
• the brake pedal is functioning optimally
• all lights are working
‒ adjust the headlight
height if the vehicle is carrying a heavy load
• tire tread depth and air pressure are at cor-rect levels. Change to snow tires when driv-ing in areas where there is a risk of snowy oricy roads.
• the start battery is sufficiently charged
• the wiper blades are in good condition

STARTING AND DRIVING
* Option/accessory.463
CAUTION
•Bumper-attached trailer hitches must not be used on Volvos, nor should safetychains be attached to the bumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
• When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
NOTE
The optional detachable trailer hitch may not be available in all markets or on all models.Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer, driving at high altitudes and fuel quality arefactors that significantly increase a vehicle'sfuel consumption.
Trailer weights
WARNING
Please adhere to the recommendations provi- ded for trailer weight. If the recommendationsare not followed, the vehicle and trailer maybe difficult to control during evasive maneu-vers and braking.
NOTE
The specified maximum trailer weights are those permitted by Volvo. National vehicleregulations may set additional restrictions ontrailer weight and speed. The trailer hitchesmay be certified for higher towing weightsthan the vehicle is permitted to tow.
Self-leveling suspension
*The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardless ofload (up to the maximum permitted weight).When the vehicle is stationary, the rear end of thevehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of overheat-ing when driving with a trailer. If overheating ofthe engine and drive system is detected, a warn-ing symbol will illuminate in the instrument panelalong with a message. The automatic transmission selects the optimalgear 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 high gears 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 vehicle is parked on a hill with a trailer attached.
Starting on a hill
1. Depress the brake pedal. 2. Put the gear selector in D.
3. Release the parking brake.
4. Release the brake pedal and start driving.

WHEELS AND TIRES
540
Tires
The function of the tires is to carry loads, provide traction on road surfaces, reduce vibrations andprotect the wheels from wear.
The tires significantly influence the vehicle's driv- ing characteristics. The type, dimensions, tirepressure and speed rating have a considerableimpact on how the vehicle performs. Your vehicle is equipped with tires according to the vehicle's tire information placard on the B-pil-lar (the structural member at the side of the vehi-cle, at the rear of the driver's door opening).
WARNING
A damaged tire could cause the driver to lose control of the vehicle.
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheel com-bination designed to provide maximum drypavement performance with consideration forhydroplaning resistance. They may be moresusceptible to road hazard damage and,depending on driving conditions, may achievea tread life of less than 30,000 km (20,000miles). Even if this vehicle is equipped withVolvo's advanced AWD or stability system,these tires are not designed for winter driving,and should be replaced with winter tires whenweather conditions dictate.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces.It should be noted however that the tires havebeen developed to give these features on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higher degree of road-holding on slippery road surfaces than tires with-out the "all-season" rating. However, for optimalroadholding on icy or snow-covered roads, werecommend snow tires on all four wheels. When replacing tires, be sure that the new tires are the same size designation, type (radial) andpreferably from the same manufacturer, on all four wheels. Otherwise there is a risk of alteringthe vehicle's roadholding and handling characte-ristics.
Recommended tiresOn delivery, the car is equipped with Volvo origi- nal tires that have the VOL
1
marking on the side
of the tires. These tires have been designed spe- cifically for your vehicle. It is therefore importantwhen replacing tires that the new tires have thissame marking to help maintain the vehicle's driv-ing characteristics, comfort and fuel consumption.
New tires
Tires are perishable goods. After a few years, they will begin to harden and their friction proper-ties will gradually deteriorate. Always replace tireswith the freshest tires possible. This is particularlyimportant for snow tires. A series of numbers is

Engine oil
For the recommended service intervals and war- ranties to be applied, an approved engine oilmust be used.
Volvo recommends:
If the engine oil is not checked regularly and the level becomes low, this could cause seriousengine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filledwith a specially adapted synthetic engine oil.Great care has been put into the choice of oil,with consideration given to service life, starta-bility, fuel consumption and environmentalimpact. For the recommended service intervals to apply, an approved engine oil must be used.Only use the prescribed oil grade to top off orchange the oil. Otherwise, there is a risk ofthe vehicle's service life, startability, fuel con-sumption and environmental impact beingaffected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low. Onengine variants with an oil pressure sensor, a warning symbol is displayed in the instrument panel when oil pressure is low
. On engine
variants with an oil level sensor, the
warn-
ing symbol in the instrument panel and display messages are used to alert the driver. Someengine variants have both systems. Contact aVolvo retailer for more information. Change the engine oil and oil filter according to the schedule specified in the Warranty and Main-tenance Records Information booklet. Oils of ahigher grade than that specified may be used. Ifthe vehicle is driven in adverse conditions, Volvorecommends using an oil with a higher gradethan that specified.

Hybrid battery
The vehicle's electric motor is powered by a rechargeable, maintenance-free, lithium-ionhybrid battery.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
NOTE
If both the starter battery and the hybrid bat- tery are discharged, both batteries must be
charged. In such cases, it is not possible to charge only the hybrid battery first. The starter battery must have a certain level of charge for it to be possible to charge thehybrid battery.
WARNING
Hybrid battery replacement may only be per- formed by a workshop – an authorized Volvoworkshop is recommended.
CoolantThe hybrid battery's cooling system has its own expansion tank.
CAUTION
Filling the hybrid battery coolant should only be performed by a workshop – an authorizedVolvo workshop is recommended.
SpecificationsType: Lithium-ion
Power reserve: 10.4 kWh.
NOTE
The capacity of the hybrid battery decreases with age and use, which could result inincreased use of the combustion engine,leading to higher fuel consumption andreduced electric motor range.
