2007 VOLVO XC70 inflation pressure

2007 Volvo XC70
CAUTION!
Drive slowly and carefully if going through standing water (i.e. floode\
d roadways, etc.). Damage to
the engine could result if excess water is drawn in through the air inta\
ke system. Never drive the
vehicle in water deeper than 1 foot (300 mm).
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, \
which means that the steering
wheel has to be turned more than might seem appropriate for the curvatur\
e of a bend.
This ensures good stability and reduces the risk of rear wheel skid. Rem\
ember that these properties can
alter with the vehicle load.
The heavier the load in the cargo area (max. 220 lbs, 100 kg), the les\
s the tendency to understeer.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle hand\
ling. Therefore, check that the tires
are inflated to the recommended pressure according to the vehicle load. \
See "Tire pressure" section.
pg. 128 Starting and driving
General driving information
Loads should be distributed so that capacity weight or maximum permissib\
le axle loads are not exceeded.
Speed-sensitive power steering (Option on certain models)
With this feature, the steering is most responsive at lower speeds to ma\
ke parking, driving in city traffic,
etc., easier. The effect of the power steering diminishes as you acceler\
ate for greater stability at highway
speeds.
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 fl\
owing 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 wa\
ter.
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.

Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread
pattern, load-, speed-, traction- , temperature-, and treadwear rating. \
Never drive on mixed tires, except
for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on
the tire inflation pressure placards, located on the driver's side B-pil\
lar (the structural member at the side
of the vehicle, at the rear of the driver's door opening), or on the in\
side of the fuel filler door on
Canadian models.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use\
only. Replace it with a full-
sized tire as soon as possible. Do not drive on the temporary spare at s\
peeds above 50 mph (80km/h) or
for distances greater than 50 miles (80 km).
Never install snow chains on a temporary spare.

Four-C active chassis system
Four-C active chassis
The FOUR-C (Continuously Controlled Chassis Concept) active chassis sy\
stem, consisting of Comfort
and Sport modes, is available as an option.
NOTE: The V70 R has a standard FOUR-C system consisting of Comfort, Sport, an\
d Advanced sport
modes. The buttons for controlling these driving modes are located in ce\
nter instrument panel, above the
ventilation system panel vents, see the illustration in the right column\
. These buttons can be pressed at
any time to change driving modes. An indicator light in the selected but\
ton will come on to indicate the
driving mode that is currently selected.
This system is based on a number of sensors that continuously monitor fa\
ctors such as the vehicle's
lateral and vertical movements, speed, and movements of the wheels. The \
sensors receive data up to 500
times per second, which is used to provide extremely fast and precise ad\
justment of each shock
absorber. The system adjusts the stiffness of the shock absorbers approx\
imately 100 times per second

Use the button in the center console to switch between the driving modes\
Comfort and Sport. This can
be done at any time.
Comfort
The Comfort mode chassis setting offers the greatest amount of shock abs\
orption and the softest ride.

General information
Your vehicle is equipped with tires according to the vehicle's tire info\
rmation placard on the B-pillar
(the structural member at the side of the vehicle, at the rear of the d\
river's door opening), or on the inside
of the fuel filler door on Canadian models.
The tires have good road holding characteristics and offer good handling\
on dry and wet surfaces. It
should be noted however that the tires have been developed to give these\
features on snow/ice-free

General information
WARNING!
l The wheel and tire sizes for your Volvo are specified to meet stringent \
stability and handling
requirements. Unapproved wheel/tire size combinations can negatively aff\
ect your vehicle's stability
and handling. Approved tire sizes are shown in the Tire inflation pressu\
re tables on
pages 160 and
161.
l Any damage caused by installation of unapproved wheel/tire size combinat\
ions will not be covered
by your new vehicle warranty. Volvo assumes no responsibility for death,\
injury, or expenses that
may result from such installations.
New tires
Remember that tires are perishable goods. As of 2000, the manufacturing \
week and year will be
indicated with 4 digits (e.g. 1502 means that the tire illustrated was \
manufactured during week 15 of
2002).
Tire age
Tires degrade over time, even when they are not being used. It is recomm\
ended that tires generally be
replaced after 6 years of normal service. Heat caused by hot climates, f\
requent high loading conditions
or Ultra Violet (U.V) exposure can accelerate the aging process.
You should replace the spare tire when you replace the other road tires \
due to the aging of the spare.
A tire's age can be determined by the DOT stamp on the sidewall (see th\
e illustration above).
A tire with e.g., visible cracks or discoloration should be replaced imm\
ediately.
Improving tire economy:
l Maintain correct tire pressure. See the tire pressure table on pages 160 and 161.
l Drive smoothly: avoid fast starts, hard braking and tire screeching.
l Tire wear increases with speed.
l Correct front wheel alignment is very important.
l Unbalanced wheels impair tire economy and driving comfort.

l Tires must maintain the same direction of rotation throughout their life\
time.
When replacing tires, the tires with the most tread should be mounted on\
the rear wheels to reduce the
chance of oversteer during hard braking.
Hitting curbs or potholes can damage the tires and/or wheels permanently\
.

Inflation pressure
Tire inflation
Check tire inflation pressure regularly.
Tables listing the recommended inflation pressure for your vehicle can b\
e found on
pages 160 and 161.
A tire inflation pressure placard is also located on the driver's side B\
-pillar (the structural member at the
side of the vehicle, at the rear of the driver's door opening). This pl\
acard indicates the designation of the
factory-mounted tires on your vehicle, as well as load limits and inflat\
ion pressure.

NOTE: The placards shown indicate inflation pressure for the tires installed \
on the vehicle at the factory
only.
l Use a tire gauge to check the tire inflation pressure, including the spa\
re, at least once a month and
before long trips. You are strongly urged to buy a reliable tire pressur\
e gauge, as automatic service
station gauges may be inaccurate.
l Use the recommended cold inflation pressure for optimum tire performance\
and wear.
l Under-inflation or over-inflation may cause uneven treadwear patterns.
WARNING!
l Under-inflation is the most common cause of tire failure and may result \
in severe tire cracking,
tread separation, or "blowout," with unexpected loss of vehicle control \
and increased risk of injury.
l Under-inflated tires reduce the load carrying capacity of your vehicle. \
When weather temperature changes occur, tire inflation pressures also ch\
ange. A 10- degree temperature
drop causes a corresponding drop of 1 psi (7 kPa) in inflation pressur\
e. Check your tire pressures
frequently and adjust them to the proper pressure, which can be found on\
the vehicle's tire information
placard or certification label.
Checking tire pressure
A certain amount of air seepage from the tires occurs naturally and tire\
pressure fluctuates with seasonal
changes in temperature. Always check tire pressure regularly.
Cold tires
Inflation pressure should be checked when the tires are cold.

Inflation pressure
The tires are considered to be cold when they have the same temperature \
as the surrounding
(ambient) air.
This temperature is normally reached after the vehicle has been parked f\
or at least 3 hours.
After driving a distance of approximately 1 mile (1.6 km), the tires a\
re considered to be hot. If you have
to drive farther than this distance to pump your tire(s), check and re\
cord the tire pressure first and add
the appropriate air pressure when you get to the pump.
If checking tire pressure when the tire is hot, never "bleed" or reduce \
air pressure. The tires are hot from
driving and it is normal for pressures to increase above recommended col\
d pressures. A hot tire at or
below recommended cold inflation pressure could be significantly under-i\
nflated.
To check inflation pressure:
- Remove the cap from the valve on one tire, then firmly press the tire \
gauge onto the valve.
- Add air to reach the recommended air pressure.
- Replace the valve cap.
- Repeat this procedure for each tire, including the spare.
- Visually inspect the tires to make sure there are no nails or other ob\
jects embedded that could puncture
the tire and cause an air leak.
- Check the sidewalls to make sure there are no gouges, cuts, bulges or \
other irregularities.
NOTE:
l If you overfill the tire, release air by pushing on the metal stem in th\
e center of the valve. Then
recheck the pressure with your tire gauge.
l Some spare tires require higher inflation pressure than the other tires.\
Consult the tire inflation table
on
pages 160 and 161 or see the inflation pressure placard.
