The earth is divided into 15 magnetic zones.
The compass is initially set for the zone to
which the car was delivered, and should
always be adjusted if the car is driven to a new
magnetic zone. A "
C" will be displayed if cali-
bration becomes necessary.
To calibrate the compass:
1. Stop the car in a large, open area, away
from traffic.
2. Using a pen or similar object, hold the but-
ton (1) depressed for at least 6 sec-
onds. "

The alarm system
The alarm is automatically armed whenever the
car is locked with the remote key, or if a front
lock button is depressed.
When armed, the alarm continuously monitors
a number of points on the car. The following
conditions will trigger the alarm:
•The hood is forced open.
•The trunk is forced open.
•A door is forced open.
•The ignition switch is tampered with
•An attempt is made to start the car with a
non-approved key (a key not coded to the
car's ignition).
•If there is movement in the passenger com-
partment (if the car is equipped with the
optional movement sensor).
•The car is lifted or towed (if the car is equip-
ped with the optional inclination sensor)
•The battery is disconnected (while the
alarm is armed).
•The siren is disconnected when the alarm
is disarmed.

139 Handling, roadholding
Vehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommended
pressure according to the vehicle load. See the
"Tire pressure" section. Loads should be dis-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.
Driving through water
The vehicle can be driven through water up to
a depth of approximately 9 in. (25 cm), at a
maximum speed of 6 mph (10 km/h).
•Take particular care when driving through
flowing water.
•Clean the electrical connections for trailer
wiring after driving in mud or water
•When driving through water, maintain low
speed and do not stop in the water.
WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
•Engine damage will occur if water is
drawn into the air cleaner.
•If the vehicle is driven through water
deeper than 9 in. (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•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, the following advice
is worth noting:
•Make sure that the engine coolant contains
50 percent antifreeze. Any other 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 byVolvo. Different types of antifreeze must
not be mixed.
•Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
Your Volvo retailer stocks plenty of Volvo
engine coolant to help protect your vehicle
during cold weather.
•Try to keep the fuel tank well filled – this
prevents the formation of condensation in
the tank. In addition, in extremely cold
weather conditions it is worthwhile to add
fuel line de-icer before refueling.
•The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type
1, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard driving
or in warm weather, see page 275 for more
information.
•The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
1Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please consult your Volvo retailer.

142
Octane rating
Minimum octane
G028920
Typical pump octane label
Volvo recommends premium fuel for best per-
formance, but using 87 octane or above will not
affect engine reliability.
Volvo engines are designed to achieve rated
horsepower, torque, and fuel economy per-
formance using premium 91 octane fuel.
Demanding drivingIn demanding driving conditions, such as oper-
ating the vehicle in hot weather, towing a trailer,
or driving for extended periods at higher alti-
tudes than normal, it may be advisable to
switch to higher octane fuel (91 or higher) or to
change gasoline brands to fully utilize yourengine's capacity, and for the smoothest pos-
sible operation.
NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticeable.
Fuel FormulationsDo not use gasoline that contains lead as a
knock inhibitor, and do not use lead additives.
Besides damaging the exhaust emission con-
trol systems on your vehicle, lead has been
strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent.
Unburned benzene has been strongly linked to
certain forms of cancer. If you live in an area
where you must fill your own gas tank, take
precautions. These may include:
•standing upwind away from the filler nozzle
while refueling
•refueling only at gas stations with vapor
recovery systems that fully seal the mouth
of the filler neck during refueling
•wearing neoprene gloves while handling a
fuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze during
winter months, do not add solvents, thicken-
ers, or other store-bought additives to your
vehicle's fuel, cooling, or lubricating systems.
Overuse may damage your engine, and some
of these additives contain organically volatile
chemicals. Do not needlessly expose yourself
to these chemicals.
WARNING
Never carry a cell phone that is switched
on while refueling your vehicle. If the phone
rings, this may cause a spark that could
ignite gasoline fumes, resulting in fire and
injury.
WARNING
Carbon monoxide is a poisonous, colorless,
and odorless gas. It is present in all exhaust
gases. If you ever smell exhaust fumes
inside the vehicle, make sure the passenger
compartment is ventilated, and immediately
return the vehicle to a trained and qualified
Volvo service technician for correction.

based on the level of acceleration and speed.
The car must be at a standstill when shifting to
position D from position R.
Manual shifting – Geartronic
The manual shifting mode (Geartronic) can be
selected at any time to manually select forward
gears, including while the car is moving.
NOTE
Reverse, Neutral, and Park cannot be
selected in Geartronic mode.
•To access the Manual (M) shifting position
from Drive (D), move the gear selector to
the right to M.
•To return to the Drive (D) position from M,
move the gear selector to the left.
While driving
•If you select the M position while driving,
the gear that was being used in the Drive
position will also initially be selected in the
M position.
•Move the gear selector forward
(toward "+") to shift to a higher gear or
rearward (toward "–") to shift to a lower
gear.
•If you hold the gear selector toward "–", the
transmission will downshift one gear at atime and will utilize the braking power of
the engine. If the current speed is too high
for using a lower gear, the downshift will
not occur until the speed has decreased
enough to allow the lower gear to be used.
•If you slow to a very low speed, the trans-
mission will automatically shift down.
Cold starts (turbo engines)
When driving before the engine has reached its
normal operating temperature, the transmis-
sion will shift up at slightly higher engine
speeds to heat the three-way catalytic con-
verter as quickly as possible.
Kickdown
Automatic shift to a lower gear (kickdown) is
achieved by depressing the accelerator pedal
fully and briskly. An upshift will occur when
approaching the top speed for a particular gear
or by releasing the accelerator pedal slightly.
Kickdown can be used for maximum acceler-
ation or when passing at highway speeds.
Safety functionTo help prevent excessive engine speeds (rpm)
that could lead to engine damage, the engine
management system includes a function that
prevents kickdown from taking place if the
engine speed is too high.Kickdown will not occur if the driver attempts
to use this function when engine speeds are
too high. The transmission will remain in the
currently selected gear.
