fuel VOLVO C30 2008 Owner's Manual

Remove your foot from the clutch pedal while driving. The shift pattern should be followed.
Overdrive (5th and 6th gears) should be used as often as possible to help improve fuel economy.
1 Clutch interlock
The clutch must be fully depressed before you can start your car. If the clutch is not depressed, it will not be possible to start the engine.
Engaging reverse gear, 6-speed transmission
Reverse gear should only be engaged from a complete stop.
NOTE
Reverse gear is electronically blocked and cannot be selected if the vehicle is moving at a speed of approximately 13
mph (20km/ h).
CAUTION
Never shift into reverse while moving forward.
WARNING
An extra mat on the driver's floor can cause the accelerator, brake, and/or clutch pedal to catch. Check that the
movement of these pedals is not impeded. Not more than one protective floor covering may be used at one time.

Towing a vehicle with a locked steering wheel will make the vehicle impossible to steer.
3. Turn the ignition key to position II.
4. Place the gear selector in neutral. For vehicles with automatic transmissions, follow instruction on page 147
,
"Shiftlock override" to allow the gear selector to be moved from the Park position.
5. Keep firm pressure on the brake pedal while releasing the parking brake.
6. When towing has been completed, return the gear selector to Park (automatic) or Reverse (manual) and apply the
parking brake.
The following points should also be observed:
Never exceed 50 mph (80 km/h). Never exceed local towing speed limits and heed all local towing restrictions.
Never tow farther than 50 miles (80 km) .
Keep the tow rope taut at all times while the vehicle is in motion.
The disabled vehicle should be towed in the forward direction only.
153 06 Starting and driving
Towing
WARNING
Never allow a vehicle to be towed without a driver behind the wheel of the disabled vehicle.
Never remove the key from the ignition while the vehicle is moving. The steering wheel could lock, making it
impossible to steer the vehicle.
When the engine is not running, steering resistance and the effort needed to apply the brakes will be great.
Never attempt to tow a vehicle with a dead battery at night.
CAUTION
Check with state and local authorities before attempting this type of towing, as vehicles being towed are subject to
regulations regarding maximum towing speed, length and type of towing device, lighting, marker flags, etc.
Never attempt to push- or tow-start a vehicle with a dead battery. This would inject unburned fuel into the three-
way catalytic converter(s), causing overheating, backfiring, and damage. See page 154
for instructions on jump
starting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equipment for towing vehicles with front wheel drive. If wheel lift equipment
must be used, please use extreme caution to help avoid damage to the vehicle.
In this case, the vehicle should be towed with the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle with the front wheels on the ground, please refer to the towing
information on the previous page.
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use sling -type equipment at the rear or apply lifting equipment inside the rear wheels;
serious damage to the rear axle may result.

WARNING
Do not connect the jumper cable to any part of the fuel system or to any moving parts. Avoid touching hot
manifolds.
Batteries generate hydrogen gas, which is flammable and explosive.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
Never expose the battery to open flame or electric spark.
Do not smoke near the battery.
Failure to follow the instructions for jump starting can lead to personal injury.
Do not touch the jumper cables during the attempt to start the vehicle. This could cause sparks.
155 06 Starting and driving
Transporting loads
Loading the vehicle
Your vehicle's load-carrying capacity is affected by factors such as:
the number of passengers
tire inflation
the amount of optional or accessory equipment installed
the amount of cargo
See the chapter "Wheels and tires" for more detailed information.
Before loading the car, turn off the engine, and apply the parking brake when loading or unloading long objects. The
gear selector can be inadvertently knocked out of position by long cargo, causing the vehicle to move.
Keep the following in mind when loading the vehicle:
Load the cargo in the cargo area against the rear seat backrest.
Load heavy cargo as low as possible.
Center wide loads.
Secure all cargo with restraining straps anchored to the load securing eyelets.
Cover sharp edges on the load.
Seats can be folded down to extend the cargo compartment. See page 108.
WARNING
Remember that an object weighing 44 lbs (20 kg) produces a force of 2,200 lbs (1,000 kg) in a head-on collision
at 30 m.p.h. (50 km/h)!
When the rear backrest(s) are folded down, the vehicle should not be loaded to a level higher than 2 in. (5 cm)
below the upper edge of the rear side windows. Objects placed higher than this level could impede the function of
the Volvo Inflatable Curtain.
Load carriers (accessory)
Load carriers are available as Volvo accessories. Follow the installation instructions supplied with the load carriers.
Observe the following points when using load carriers:

To avoid damaging your vehicle and to achieve maximum safety when driving, we recommend using the load
carriers that Volvo has developed especially for your car.
Volvo-approved removable roof racks are designed to carry the maximum allowable roof load for this vehicle: 165
lbs (75 kg). For Non-Volvo roof racks, check the manufacturer's weight limits for the rack.
Never exceed the rack manufacturer's weigh limits and never exceed the maximum rated roof load of 165 lbs (75
kg).
Avoid single-point loads. Distribute loads evenly.
Place heavier cargo at the bottom of the load.
Secure the cargo correctly with appropriate tie-down equipment.
Check periodically that the load carriers and load are properly secured.
Remember that the car's center of gravity and handling change when you carry a load on the roof.
The car's wind resistance and fuel consumption will increase with the size of the load.
Drive smoothly. Avoid rapid starts, fast cornering and hard braking.
156 06 Starting and driving
Blind Spot Information System (BLIS)-option
Introduction
1. BLIS camera
2. Indicator light
3. BLIS symbol
The Blind Spot Information System (BLIS) is an information system that indicates the presence of another vehicle
moving in the same direction as your vehicle in the sideview mirror's "blind area."
CAUTION
The BLIS system should only be repaired by a trained and qualified Volvo service technician.
WARNING
BLIS is an information system, NOT a warning or safety system.
BLIS does not eliminate the need for you to visually confirm the conditions around you, and the need for you to
turn your head and shoulders to make sure that you can safely change lanes.
As the driver, you have full responsibility for changing lanes in a safe manner.

General information
Your vehicle is equipped with tires according to the vehicle's tire information placard on the B-pillar (the structural
member at the side of the vehicle, at the rear of the driver'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 surfaces.
Certain models are equipped with "all-season" tires, which provide a somewhat higher degree of road holding on
slippery surfaces than tires without the "all-season" rating. However, for optimum road holding on icy or snow-
covered roads, we recommend suitable winter tires on all four wheels.

1Optional pressure may not be used for homologation of fuel consumption or emissions.
2Tires of this type may not be mounted on vehicles equipped with the optional self- leveling system.
172 07 Wheels and tires
Tire designations
Federal law mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a tire designation):
1. 215: the width of the tire (in millimeters) from sidewall edge to sidewall edge. The larger the number, the wider the
tire.
2. 65: The ratio of the tire's height to its width.
3. R: Radial tire.
4. 15: The diameter of the wheel rim (in inches).
5. 95: The tire's load index. In this example, a load index of 95 equals a maximum load of 1521 lbs (690 kg).

6. H: The tire's speed rating, or the maximum speed at which the tire is designed to be driven for extended periods of
time, carrying a permissible load for the vehicle, and with correct inflation pressure. For example, H indicates a speed
rating of 130 mph (210 km/h).
NOTE
This information may not appear on the tire because it is not required by law.
7. M+S or M/S = Mud and Snow, AT = All Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and indicates that the tire meets
all federal standards. The next two numbers or letters are the plant code where it was manufactured, the next two are
the tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers
317 mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of
2001. The numbers in between are marketing codes used at the manufacturer's discretion. This information helps a tire
manufacturer identify a tire for safety recall purposes.
9. Tire Ply Composition and Material Used: Indicates the number of plies indicates or the number of layers of rubber-
coated fabric in the tire tread and sidewall. Tire manufacturers also must indicate the ply materials in the tire and the
sidewall, which include steel, nylon, polyester, and others.
10. Maximum Load : Indicates the maximum load in pounds and kilograms that can be carried by the tire. Refer to the
vehicle's tire information placard or the safety certification label, located on the B-Pillar or the driver's door or on the
inside of the fuel filler door on Canadian models, for the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperature grades : See page 176
for more information.

Tire designations
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire.
This limit is set by the tire manufacturer.
The tire suppliers may have additional markings, notes or warnings such as standard load, radial tubeless, etc.

Glossary of tire terminology
Tire terminology
Tire information placard : A placard showing the OE (Original Equipment) tire sizes, recommended inflation
pressure, and the maximum weight the vehicle can carry.
Tire Identification Number (TIN) : A number on the sidewall of each tire providing information about the tire
brand and manufacturing plant, tire size and date of manufacturer.
Inflation pressure : A measure of the amount of air in a tire.
Standard load: A class of P-metric or Metric tires designed to carry a maximum load at 35 psi [37 psi (2.5 bar) for
Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying capability.
Extra load : A class of P-metric or Metric tires designed to carry a heavier maximum load at 41 psi [43 psi (2.9 bar)
for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying

capability.
kPa: Kilopascal, a metric unit of air pressure.
PSI: Pounds per square inch, a standard unit of air pressure.
B-pillar : The structural member at the side of the vehicle behind the front door.
Bead area of the tire : Area of the tire next to the rim.
Sidewall of the tire: Area between the bead area and the tread.
Tread area of the tire : Area of the perimeter of the tire that contacts the road when mounted on the vehicle.
Rim: The metal support (wheel) for a tire or a tire and tube assembly upon which the tire beads are seated.
Maximum load rating : a figure indicating the maximum load in pounds and kilograms that can be carried by the
tire. This rating is established by the tire manufacturer.
Maximum permissible inflation pressure : the greatest amount of air pressure that should ever be put in the tire.
This limit is set by the tire manufacturer.
Recommended tire inflation pressure : inflation pressure, established by Volvo, which is based on the type of tires
that are mounted on a vehicle at the factory. This inflation pressure is affected by the number of occupants in the car,
the amount of cargo, and the speed at which the vehicle will be driven for a prolonged period. This information can be
found on the tire inflation placard(s) located on the driver's side B-pillar or on the inside of the fuel filler door on
Canadian models, and in the tire inflation table in this chapter.
Cold tires : 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 for at least 3 hours.
Properly loading your vehicle will provide maximum return of vehicle design performance.
175 07 Wheels and tires
Carrying loads
Vehicle loading
Before loading your vehicle, familiarize yourself with the following terms for determining your vehicle's weight
ratings, with or without a trailer, from the vehicle's Federal/Canadian Motor Vehicle Safety Standards
(FMVSS/CMVSS) label, and the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does not include passengers,
cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing, trailer hitch tongue load
is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). These numbers are shown on the
Federal/Canadian Motor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axle must never
exceed its maximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
NOTE
The location of the various labels in your vehicle can be found on page 247
.
A table listing important weight limits for your vehicle can be found on page 249.

Summer and winter tires
When switching between summer and winter tires, mark the tires to indicate where they were mounted on the car,
e.g. LF = left front, RR = right rear
Tires with tread designed to roll in only one direction are marked with an arrow on the sidewall.
Incorrectly mounted tires impair the car's braking properties and ability to force aside rain, snow and slush.
The tires with the most tread should always be at the rear (to reduce the risk of skidding).
Contact a Volvo workshop if you are unsure about the tread depth.
Tire rotation
Your vehicle has no recommended tire rotation. The following information is intended to help you understand why.
Tread set
As a tire ages and the rubber cures, front and rear tires set at different angles. Therefore, if tires are rotated, the tread
will eventually set at an angle that is a compromise. Even if ride, handling, and road noise may still seem acceptable,
they may not be optimal. Further, tires that are rotated, but not on a regular basis, may actually cause more tire noise,
faster tire wear, and unpleasant changes in steering feel and vehicle handling.
A tire that can fully adapt to its position will provide better steering feel, lower tire noise, and better fuel economy.
Braking stability performance
Your vehicle is driven mainly by the front tires, which will wear faster. This can be beneficial. Having more tread on
the rear tires will help reduce oversteer. Oversteer is when a vehicle wants to keep turning because of momentum and
dynamic forces on its suspension.
Suspension wear diagnostics
Every suspension needs periodic inspection and maintenance. A tire's wear pattern can be an aid in detecting a
suspension problem. Each tire, if left in place, tells a story about the suspension. Tire rotation, on the other hand, could
make suspension wear harder to detect. Early detection is very important, because suspension problems can make tire
wear worse.
If you do rotate your tires...
Please follow the tire manufacturer's recommendations, as outlined in the tire manufacturers tire warranty pamphlet.

tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
185 07 Wheels and tires
Tire Pressure Monitoring System (TPMS)
NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire
pressure, please refer to the tables beginning on page 170
, or consult your Volvo retailer.
The tire pressure warning light will not identify which tire is underinflated. Be sure to check all four tires.
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.
Erasing warning messages
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
1. Use a tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the tables beginning on page 170
).
3. In certain cases, it may be necessary to drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or
faster. This will erase the warning text and the warning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of the vehicle.
Changing wheels with TPMS
Please note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary spare tire, this tire does not have a TPMS sensor.
If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SYST SERVICE REQUIRED will be
displayed each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed, the warning message should not reappear. If the message is still
displayed, drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster to erase the message.
