stop and let the engine idle for a few
minutes.
•
If the car overheats, the air conditioning
may be switched off temporarily.
•
Do not turn the engine off immediately you
stop after a hard drive.
For supplementary information about over-
heating when driving with a trailer - see
page 162.
NOTE
It is normal for the engine's cooling fan to
operate for a while after the engine has been
switched off.
Open tailgate
WARNING
Do not drive with the tailgate open. Toxic
exhaust fumes can be drawn into the car
through the cargo area.
Do not overload the battery
The electrical functions in the car load the bat-
tery to varying degrees. Avoid having the
remote control key in key position II when the
engine is switched off. Instead use the I mode
- which uses less power.
Note that the 12 volt outlet in the cargo area
supplies power even when the remote control
key has been removed from the ignition switch.
Also, be aware of different accessories that
load the electrical system. Do not use functions
which use a lot of power when the engine is
switched off. Examples of such functions are:
•
ventilation fan
•
windscreen wiper
•
audio system (high volume)
•
headlamps.
If the battery voltage is low the information dis-
LOW BATTERY POWER
play shows the text
SAVE MODE . The energy-saving function
then shuts down certain functions or reduces
certain functions such as the ventilation fan
and/or audio system.

In which case, charge the battery by star-
ting the engine and then running it for at
least 15 minutes - battery charging is more
effective during driving than running the
engine at idling speed while stationary.
06 Starting and driving
Driving on rough roads
The Volvo XC90 is primarily designed for driv-
ing on main roads, but also has good handling
properties on uneven or rough roads. Keep the
following in mind in order to preserve the serv-
ice life of your car:
•
Drive slowly on rough roads - this avoids
damaging the car's underbody.
•
If the ground is loose or is made up of dry
sand or snow, it is always best to keep the
car moving at all times and avoid shifting.
Do not stop the car.
•
If the road is extremely steep and there is
a risk of overturning - never try to turn the
car around. Reverse back down instead.
•
Do not drive diagonally across an incline -
drive in the direction of the incline.
NOTE
Avoid driving on steep slopes if the fuel level
is low. The catalytic converter could be
damaged if the engine does not receive
enough fuel. When driving on extremely
steep slopes, make sure the tank is more
than half full to avoid the risk of breakdown.
Slippery driving conditions
Practise driving on slippery surfaces under
controlled conditions to learn how the car
reacts.
