Turn signal indicators – right/left
Text window – The text window displays information and warning messages.
Temperature gauge – The pointer should be approximately midway on the gaugewhen driving. Do not drive the vehicle if
the warning light is on. The text window
will provide you with additional informa-tion. If the engine temperature remainshigh, check coolant level – see page 224.
Trip odometer – The trip odometers are used for measuring shorter distances.The right-hand digit gives tenth of a mile/kilometer. Press the button for more than2 seconds to reset. Change between trip odometers 1 and 2 using one short presson the button. The display presents infor-mation and warning messages, the ambi-ent temperature, and the clock, etc.When the ambient temperature isbetween 23° and 36 °F (–5° and +2 °C), asnowflake symbol is shown in the display.This symbol serves as a warning for pos-sible slippery road surfaces. Please notethat this symbol does not indicate a faultwith your car. At low speeds, or when thecar is not moving, the temperature read-ings may be slightly higher than theactual ambient temperature.

Tachometer – The tachometer shows engine speed in thousands of revolutionsper minute (rpm). Do not drive continu-ously with the needle in the red area ofthe dial, which indicates maximum allow-able engine rpm range. Instead, shift to ahigher gear or slow the vehicle down. Theengine management system will automat-ically prevent excessively high enginesspeeds. This will be noticeable as a pro-nounced unevenness in engine speed.

Cold weather precautions

If you wish to check your vehicle before the approach of cold weather, the followingadvice is worth noting:
• Make sure that the engine coolant con- tains 50 percent antifreeze. Any othermixture will reduce freeze protection. Thisgives protection against freezing down to–31 °F (–35 °C). See section "Coolant".
• The use of "recycled" antifreeze is notapproved by Volvo. Different types ofantifreeze must not be mixed.
• Volvo recommends using only genuineVolvo antifreeze in your vehicle's radiator.Your Volvo retailer stocks plenty of Volvoengine coolant to protect your vehicleduring cold weather.
• Try to keep the
fuel tank well filled – this
prevents the formation of condensation inthe tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
• The viscosity of the engine oil is impor-tant. Oil with low viscosity (thinner oil)improves cold-weather starting as well asdecreasing fuel consumption while theengine is warming up. Full synthetic0W-30 oil is recommended for driving inareas with sustained low temperatures.
• The load placed on the
battery is greater
during the winter since the windshieldwipers, lighting, etc. are used more often. Moreover, the capacity of the batterydecreases as the temperature drops. Invery cold weather, a poorly charged bat-tery can freeze and be damaged. It istherefore advisable to check the state ofcharge more frequently and spray an anti-rust oil on the battery posts.
• Volvo recommends the use of
snow tires
on all four wheels for winter driving – seesection "Wheels and tires."
• To prevent the
washer fluid reservoir
from freezing, add washer solvents con-taining antifreeze (see page 224 for thelocation of the washer fluid reservoir).This is important since dirt is oftensplashed on the windshield during winterdriving, requiring the frequent use of thewashers and wipers. Volvo Washer Sol-vent should be diluted as follows:
• Down to 14 ° F (–10 ° C):
1 part washer
solvent and 4 parts water
• Down to 5 ° F (–15 ° C):
1 part washer
solvent and 3 parts water
• Down to 0 ° F (–18 ° C):
1 part washer
solvent and 2 parts water
• Down to –18 ° F (–28 ° C):
1 part washer
solvent and 1 part water
• Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid the use of de-icing sprays as they can cause damage to the locks.
W – Winter/Wet driving mode – enhanced vehicle traction
•Mode W will only function if the gear selector is in the (
D)rive position.
• Press the button at the base of the gearselector to engage/disengage this drivingmode.
• An LED in the button will light up to indi-cate that W is engaged and this will alsobe displayed in the instrument panel (seepage 58).
• This mode may be selected for starting/moving off on slippery roads.

Belt check
Check the belt regularly to make sure it is in good condition and is clean. A worn or dirtybelt can cause poor cooling and low alterna-tor output as well as impair the operation ofthe power steering and the air conditioningunit.
NOTE
The drive belt is equipped with a self-ten- sioning mechanism and requires noadjustment between changes.
WARNING
The engine must not be running when this check is performed.
Check coolant level
The cooling system must be filled with cool- ant and not leak to operate at maximum effi-ciency. Check the coolant level regularly. Thelevel should be between the MAX and MIN
marks on the expansion tank. The checkshould be made with particular thoroughnesswhen the engine is new or when the coolingsystem has been drained. Do not remove the filler cap other than for topping up with coolant. Frequent removalmay prevent coolant circulation between the engine and the expansion tank during enginewarm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. Do not top off with water only. This reduces the rust-protective and antifreeze qualities ofthe coolant and has a lower boiling point. Itcan also cause damage to the cooling systemif it should freeze. Top off with Volvo GenuineCoolant/Antifreeze only (a 50/50 mix of waterand antifreeze.
CAUTION
The cooling system must always be kept filled to the correct level. If it is not keptfilled, there can be high local temperaturesin the engine which could result in dam-age. Different types of antifreeze/coolantmay not be mixed.
WARNING
•
Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.

Washer fluid reservoir
G027097
Washer fluid reservoirThe washer fluid reservoir is located in the engine compartment and holds approx.6.8 US qts (6.5 liters). When there is less than approximately 1 US qt (1 liter) remaining in the reservoir, thewasher fluid spray will be directed to thewindshield only. During cold weather, the reservoir should be filled with windshield washer solvent contain-ing antifreeze.

Coolant reservoir
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician.
CAUTION
• If necessary, top up the cooling sys- tem with Volvo Genuine Coolant/Anti-freeze only (a 50/50 mix of water andantifreeze).
• Different types of antifreeze/coolantmay not be mixed.
• If the cooling system is drained, itshould be flushed with clean water orpremixed anti-freeze before it is refilledwith the correct mixture of water/anti-freeze.
• The cooling system must always bekept filled to the correct level, and thelevel must be between the
MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in theengine which could result in damage.Check coolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and hasa lower boiling point. It can also causedamage to the cooling system if itshould freeze.
• Do not use chlorinated tap water in thevehicle's cooling system.

The transmission oil does not normally need to be changed during the service life of the vehicle. However, it may be necessary to replace the oil if the vehicle is often driven in areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, for prolonged driving in mountainous areas, or if the vehicle is often driven short distances in temperatures under40 °F (5 °C).
