Audio System - Volvo XC90 Owner's Manual

Do not overload the battery
The electrical functions in the car load the
battery to varying degrees. Avoid having the
ignition key in position II when the engine is
turned off. Use position I instead, as less
power is used. The 12 volt outlet in the cargo
area supplies power even when the ignition
key is removed.
Examples of functions that use a lot of power:
• ventilation fan
• windscreen wipers

• audio system

• parking lights
Also take note of different accessories that
load the electrical system. Do not use
functions the consume a lot of current when
the engine is switched off. A text is shown on
the display in the combined instrument panel
if battery voltage is low and remains until the
engine has started. The energy economy
function shuts down certain functions or
reduces the load on the battery, e.g. by
lowering ventilation fan speed and switching
off the audio system.
Charge the battery by starting the engine.
Do not allow the engine and
cooling system to overheat
Under certain conditions, e.g. when driving in
hilly terrain or with a heavy load, especially in
warm weather, there is a risk of the engine
and cooling system overheating.
To avoid the cooling system
overheating
• Drive at low speeds if driving with a trailer
up a long incline.
• Do not turn the engine off immediately
you stop, if the car has been driven hard.
• Remove any auxiliary lamps from in front
of the grille if driving in extreme high
temperatures.
To avoid the engine overheating
Do not exceed engine speeds of 4500 rpm if
driving with a trailer or caravan in hilly terrain.
The oil temperature can become too high.
Do not drive with an open
tailgate!
If you drive with the tailgate open, some of the
exhaust gases and poisonous carbon
monoxide could be sucked into the car
through the cargo compartment. If you must
drive a short distance with the tailgate open,
do as follows:
• Close all windows.
• Distribute the air between the windscreen
and floor while running the fan at high
speed.
