Volvo XC90: Starting and driving / Winter driving
It is important to check the vehicle before driving in cold/snowy conditions
to make sure it can be driven safely.
Before the cold season arrives:
- Make sure the engine coolant contains 50% antifreeze. This mixture helps
protect the engine from frost erosion down to approx. –35 °C (–31 °F). Do not
mix different types of antifreeze as this could pose a health risk.
- Keep the fuel tank well filled to prevent condensation from forming.
- Check the viscosity of the engine oil. Oil with low viscosity (thinner oil)
improves cold-weather starting and reduces fuel consumption when driving with
a cold engine.
- Check the condition and charge level of the start battery. Cold weather
places greater demands on the start battery and reduces its capacity.
- Use washer fluid containing antifreeze to help prevent ice from forming
in the washer fluid reservoir.
See separate section for engine oil recommendations.
Slippery driving conditions
To help optimize traction and roadholding, Volvo recommends using snow tires
on all wheels whenever there is a risk of snow or ice on the road.
NOTE
Certain countries require use of winter tires by law. Not all countries
permit the use of studded tires.
Practice driving on slippery surfaces under controlled conditions to learn how
the vehicle reacts.
It is important to have the vehicle's systems and equipment checked carefully
before driving long distances.
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 properly
tire tread depth and air pressure are at correct levels...
It may be necessary to drive the vehicle through standing water e.g. deep
puddles or flooding on the road. This must be done with great caution.
The vehicle can be driven through water up to a depth of 45 cm (17 in) at no
more than walking speed...
Other information:
(Not available on all models.)
The spare wheel is a Temporary Spare and can be used to temporarily replace
a punctured tire on one of the vehicle's regular wheels.
The spare wheel is only intended for temporary use. Replace it with a normal
wheel as soon as possible...
Cruise control (CC1) can be deactivated and put in standby mode.
This may happen automatically or be due to driver intervention. Standby mode means
that the function is selected in the instrument panel but not activated. In standby
mode, cruise control will not regulate speed...
