The gauge indicates the temperature of the engine cooling system. If the\
temperature is abnormally high and the
needle enters the red zone, a message is shown in the display. Bear in m\
ind that auxiliary lamps in front of the air
intake reduce the cooling capacity at high outside temperatures and high\
engine loads.

122 06 Starting and driving
General information
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid\
starts and stops and adjusting
the speed of your vehicle to immediate traffic conditions.
Observe the following rules:
l Bring the engine to normal operating temperature as soon as possible by \
driving with a light foot on the
accelerator pedal for the first few minutes of operation. A cold engine \
uses more fuel and is subject to
increased wear.
l Whenever possible, avoid using the vehicle for driving short distances. \
This does not allow the engine
to reach normal operating temperature.
l Drive carefully and avoid rapid acceleration and hard braking.
l Use the transmission's Drive (D) position as often as possible and avo\
id using kickdown.
l Do not exceed posted speed limits.
l Avoid carrying unnecessary items (extra load) in the vehicle.
l Maintain correct tire pressure. Check tire pressure regularly (when tir\
es are cold).
l Remove snow tires when threat of snow or ice has ended.
l At highway driving speeds, fuel consumption will be lower with the air c\
onditioning on and the
windows closed than with the air conditioning off and the windows open. \
l Using the onboard trip computer's fuel consumption modes can help you le\
arn how to drive more
economically.
Other factors that decrease gas mileage are:
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard\
maintenance intervals.
Avoid overheating the engine
Do not drive at engine speeds above 4,500 rpm if you tow a trailer in hi\
lly areas. This could cause the
engine oil to overheat.

CAUTION
l Engine damage will occur if water is drawn into the air cleaner.
l If the vehicle is driven through water deeper than 9 in (25 cm), water\
may enter the differential and
the transmission. This reduces the oil's lubricating capacity and may sh\
orten the service life of these
components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This
could result in electrical malfunctions.
l If the engine has been stopped while the car is in water, do not attempt\
to restart the engine. Have the
car towed out of the water.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth
noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce freeze
protection. This gives protection against freezing down to - 31°F (-\
35°C). See section "Coolant". The use
of "recycled" antifreeze is not approved by Volvo. Different types of an\
tifreeze must not be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo retailer
stocks plenty of Volvo engine coolant to help protect your vehicle durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of c\
ondensation in the tank. In
addition, in extremely cold weather conditions it is worthwhile to add f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing up. For winter use, 5W-30
oil, particularly the synthetic type
1, is recommended. Be sure to use good quality oil but do not use cold-
weather oil for hard driving or in warm weather. See
page 239 for more information.
l The load placed on the battery is greater during the winter since the wi\
ndshield wipers, lighting, etc. are
used more often. Moreover, the capacity of the battery decreases as the \
temperature drops. In very cold
weather, a poorly charged battery can freeze and be damaged. It is there\
fore advisable to check the state
of

nce intervals except at owner request and
at additional charge. Please consult your Volvo retailer.

General information
charge more frequently and spray an antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter dri\
ving - see the chapter "Wheels
and tires."

(Shiftlock). Manual transmission: the clutch must be fully depressed.
3. The vehicle is equipped with an autostart feature. Without touching t\
he throttle pedal, turn the key to
position III and release it. The starter motor will then operate automat\
ically (for up to ten seconds) until
the engine starts. If the engine fails to start, repeat this step.
NOTE
After a cold start, idle speed may be noticeably higher than normal for \
a short period. This is done to
help bring components in the emission control system to their normal ope\
rating temperature as quickly
as possible, which enables them to control emissions and help reduce the\
vehicle's impact on the
environment.
4. To release the gear selector from the Park (P) position, the engine must be running (or the ignition key
must be in position II) and the brake pedal must be depressed.
5. Select the desired gear. On models with an automatic transmission, th\
e gear engages after a very slight
delay which is especially noticeable when selecting R.
NOTE
l Immobilizer: If two of the keys to your vehicle are close together, e.g., on the sa\
me key ring when
you try to start the vehicle, this could cause interference in the immob\
ilizer system and result in the
vehicle not starting. If this should occur, remove one of the keys from \
the key ring before trying to start
the vehicle again.
l Keylock: Models equipped an automatic transmission have a keylock system. When \
the engine is
switched off, the gear selector must be in the Park (P) position before the key can be removed from the
ignition switch.
l When starting in cold weather, the transmission may shift up at slightly\
higher engine speeds than
normal until the automatic transmission fluid reaches normal operating t\
emperature.
l Do not race a cold engine immediately after starting. Oil flow may not r\
each some lubrication points
fast enough to prevent engine damage.
WARNING
Volvo's floor mats are specially manufactured for your car. They must be\
firmly secured in the clips on
the floor so that they cannot slide and become trapped under the pedals \
on the driver's side.

NOTE
Volvo does not recommend the use of oil additives.
l Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner
request and at additional charge. Please consult your Volvo retailer.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This\
is especially important during the
period up to the first scheduled maintenance service
l The car should be parked on a level surface when the oil is checked.
l If the engine is warm, wait for at least 10-15 minutes after the engine has been switched off \
before
checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add appr\
oximately 1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal operating temperature.
5. Switch off the engine and wait for at least 10-15 minutes and recheck\
the oil level. If necessary, add oil
until the level is near the MAX mark.

Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is changed at the normal service \
intervals. This oil is only used at customer
request, at additional charge. Please consult your Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 86° F (30° C) in your area, Volvo recom\
mends, for the protection of your engine, that
you use a heavier weight oil, such as such as SAE 5W-40 or 0W-40. See th\
e viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86° F (30° C),
SAE 5W-30 will provide good fuel economy and engine protection. See the \
viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 0W-30 or 0W-40 and complying with oil quality\
requirements are recommended for
