Preparing for a long trip
It is important to have the vehicle's systems andequipment checked carefully before driving longdistances.
Check that:
the engine is running properly and that fuelconsumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlightheight 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

CAUTION
Parts of the vehicle (e.g. engine, transmission,driveline, electrical components, etc.) can bedamaged if the vehicle is driven through waterhigher than its floor level. Damage to anycomponents caused by flooding, vapor lock orinsufficient oil is not covered under warranty.
If the engine stalls while the vehicle is inwater, do not attempt to restart it. Have thevehicle towed on the bed of a tow truck to aworkshop - an authorized Volvo workshop isrecommended.

CAUTION
Because it can be difficult to determine thewater depth, avoid driving through standing orrunning water.
When you have passed the water, press lightly onthe brake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc. canmake the brake linings slippery, resulting indelayed braking effect.
If the vehicle is equipped with a trailer couplingcontact, clean the contact after driving in water ormud.

the emission control system and could result inloss of emission warranty coverage. State andlocal vehicle inspection programs will makedetection of misfueling easier, possibly resultingin emission test failure for misfueled vehicles.

NOTE
Some U.S. and Canadian gasolines contain anoctane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl(MMT). If such fuels are used, your EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle to a trained and qualified Volvoservice technician for service.

Gasoline containing alcohol and ethers,
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing"oxygenates" which are usually alcohols orethers. In some areas, state or local laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. To meet seasonal air quality standards,some areas require the use of "oxygenated" fuel.
Volvo permits the use of the following "oxygen-ated" fuels. However, the specified octane ratingsmust still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volumemay be used. Ethanol may also be referred to asEthyl alcohol, or "Gasohol".
Ethers - MTBE/ETBE: Fuels containing up to22% MTBE/ETBE by volume may be used.

Methanol
Do not use gasolines containing methanol(methyl alcohol, wood alcohol). This practice canresult in vehicle performance deterioration andcan damage critical parts in the fuel system. Suchdamage may not be covered under the NewVehicle Limited Warranty.

Overheating of engine andtransmission
In demanding driving conditions, such as drivingin mountainous areas or hot weather, there is arisk of the engine or transmission overheating,especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in frontof the grille when driving in hot weather.
If the temperature in the engine's coolingsystem becomes too high, a warning symbolwill appear in the instrument panel along withthe message Engine temperature Hightemperature Stop safely. Pull over to asafe location and let the engine idle for a fewminutes to cool down.
If the message Engine temperature Hightemperature Turn off engine or Enginecoolant Level low, turn off engine is dis-played, stop the vehicle and turn off theengine.
If the transmission begins to overheat, analternative gear shifting program will beselected. An integrated protective functionwill also be activated, the warning symbol willilluminate and the message Transmissionwarm Reduce speed to lowertemperature or Transmission hot Stopsafely, wait for cooling will be displayed inthe instrument panel. Follow the recommen-dations given by reducing speed or stopping
the vehicle safely and letting the engine idlefor a few minutes to let the transmissioncool.
If the vehicle begins to overheat, the air con-ditioning may be temporarily switched off.
After a prolonged period of driving indemanding conditions, do not turn off theengine immediately after stopping.

Battery drain
The electrical functions in the vehicle drain thebattery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Useignition mode I instead, as this uses less electri-cal current.
Note that certain accessories may also drainpower from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audiosystem.
–Charge the battery by starting the engineand let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

2.Make sure the auxiliary battery (the batteryused 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 make surethat the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliarybattery's positive (+) terminal (1).

CAUTION
Connect the jump cable carefully to preventshort circuits with other components in theengine compartment.
5. Fold back the cover over your vehicle's posi-tive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cableto your vehicle's positive (+) jump start termi-nal (2).
7.Clamp the black jumper cable onto the auxili-ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumpercable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securelyattached to help prevent sparks while jumpstarting.
10. Start the engine of the assisting vehicle andlet it run for a few minutes at a higher idlingspeed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the enginedoes not start, allow an additional 10minutes of charging time and then try to startthe engine again.
NOTE
When the engine is started under normalconditions, the vehicle's electrical drive motoris prioritized – the gasoline engine remainsoff. This means that the electric motor has"started" and the vehicle is ready to be drivenonce the start knob has been turned clock-wise. Start of the electric motor is indicatedby the indicator lights on the instrument panelgoing out and its preselected theme illuminat-ing.

CAUTION
