Engine and cooling system
Under special conditions, for example when driving in hilly terrain, extreme heat or withheavy loads, there is a risk that the engine andcooling system will overheat. Proceed as follows to avoid overheating the engine. •Maintain a low speed when driving with a trailer up long, steep hills. For informa-tion, see Towing a trailer (p. 281)
• Do not turn the engine off immediatelywhen stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after theengine has been switched off.
•
Remove any auxiliary lights from in front of the grille when driving in hot weatherconditions.
• Do not exceed engine speeds of4500 rpm if driving with a trailer in hillyterrain. The oil temperature could becometoo high.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
• When the engine is not running, avoid using ignition mode
II. Many electrical
systems (the audio system, the optionalnavigation system, power windows, etc)will function in ignition modes 0 and I.
These modes reduce drain on the battery.
• Please keep in mind that using systems,accessories, etc., that consume a greatdeal of current when the engine is notrunning could result in the battery beingcompletely drained. Driving or having theengine running for approximately15 minutes will help keep the batterycharged.
• The optional 12-volt socket in the cargoarea (p. 141) area provides electrical cur-rent even with the ignition switched off,which drains the battery.
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo serv-ice technician before driving long distances.Your retailer will also be able to supply youwith bulbs, fuses, spark plugs and wiperblades for your use in the event that problemsoccur. As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and that fuel consumption is normal.
• Check for fuel, oil, and fluid leakage.
• Have the transmission oil level (p. 377)checked.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that areworn (p. 290). Check tire pres-sure (p. 297).
• The brakes, front wheel alignment, andsteering gear should be checked by atrained and qualified Volvo service techni-cian only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to
