2003 VOLVO V70 engine

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 "Tire pressure" section. Loads should be distributed so
that capacity weight or maximum permissible axle loads are not exceeded.
pg. 96 Points to remember
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should be followed: Do not drive for prolonged periods at engine speeds
above 4500 rpm if you are towing a trailer in hilly terrain.
Reduce speed when towing a trailer up long, steep inclines. The risk of overheating can be reduced by switching off
the air conditioning system for a short time.
Do not let the engine idle unnecessarily for prolonged periods.
Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating (the temperature gauge goes repeatedly into,
or stays continually in, the red section), the following precautions should be taken:
Switch off the air conditioning system.
Pull off the road, away from traffic, stop the car and put the gear selector into neutral.
Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely hot.
If necessary, see page 129
and 132 for information on checking and topping-up the coolant level.
CAUTION: Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the
engine could result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper
than 1 foot (300 mm). See the flood warning on page 7
.
WARNING!
Driving with the tailgate open : Driving with the tailgate open could mean that poisonous exhaust gases enter the
passenger compartment.
If the tailgate must be kept open for any reason, proceed as follows:
- Close the windows.
- Set the ventilation system control to air flow to floor, windshield and side windows and blower control to its
highest setting.
Floor mats : An extra mat on the driver's floor can cause the accelerator pedal to catch. Check that the movement
of the accelerator pedal is not impeded. Not more than one protective floor covering may be used at one time.

Electrical system
When replacing the battery or when carrying out work involving the electrical system, the following should be
observed:
A battery connection to the wrong terminal will damage the electrical system. Be sure to connect the positive battery
cable to the positive battery terminal and the negative battery cable to the negative battery terminal.
If booster batteries are used for starting, they must be properly connected to minimize the risk of the electrical
system being damaged. For correct connection, see "Jump starting" section.
Never disconnect the battery circuit (for example, to replace the battery) while the engine is running, as this may
damage the generator. Always make sure that all the battery connections are properly cleaned and tightened.
If any electrical welding work is performed on the vehicle, the battery's ground lead (negative cable) and all the
connecting cables of the generator must be disconnected and the welder cables placed as near the welding points as
possible.
The radio must be turned off before the battery is disconnected.
Switch off the ignition for at least 10 minutes before disconnecting the battery.
pg. 97 Roof racks/Load carriers
Load carriers (accessory)
Load carriers are available as Volvo accessories. Observe the following points when in use:
To avoid damaging your car 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: 220
lbs (100 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 220 lbs (100
kg).
Avoid single-point loads. Distribute loads evenly.
Place heavier cargo at the bottom of the load.
Anchor 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 correspondingly, fuel consumption) will increase with the size of the load.
Drive smoothly. Avoid rapid starts, fast cornering and hard braking.
Load carrier attachment points
Attaching load carriers (models without rails)
The attachment brackets for the load carriers are located under the roof molding.

original hand -held transmitter can also be used, as desired, to operate the garage door.
The remaining two HomeLink® buttons can be programmed in the same way. In the event of any problems in
programming the HomeLink® Universal Transceiver, call toll-free 1-800-355-3515 (Internet: www.HomeLink.com
).
Operating the HomeLink® Universal Transceiver
Once programmed, the HomeLink® Universal Transceiver can be used in place of your hand -held transmitters.
To operate, the key must be turned to the "accessory" position (II) or the engine must be running. Press the
programmed HomeLink® button to activate the garage door, driveway gate, security lighting, home security system,
etc.
Your original hand -held transmitters may, of course, be used at any time.
Erasing programmed buttons
Individual buttons cannot be erased. To erase all three programmed buttons:
1. Turn the ignition key to the "accessory" position (II).
2. Hold down the two outside buttons on the HomeLink® Universal Transceiver for about 20 seconds, until
HomeLink®'s indicator light begins to flash.
3. Release both buttons.
The HomeLink® buttons can be reprogrammed using the procedures described on the previous page.
(HomeLink® information continues on the next page)
pg. 169 HomeLink® Universal Transceiver (option)
Reprogramming a single HomeLink® button
1. Press and hold the desired HomeLink® button. Do not release the button until step 3 has been completed.
2. When the indicator light begins to flash slowly (after approximately 20 seconds), position your hand -held
transmitter 2 to 5 in. (5 to 12 cm) away from the HomeLink® surface.
3. Press and hold the hand -held transmitter button. The HomeLink® indicator light will flash first slowly, then rapidly.
When the indicator light flashes rapidly, release both buttons.
The previously programmed device has now been erased and the new device can be activated by pressing the
HomeLink® button that has just been programmed. This procedure will not affect any other programmed HomeLink®
buttons.
NOTE:
Retain the original transmitter(s) for future programming procedures (e.g., if you purchase a new car).
For your own security, erase all programmed buttons on the HomeLink® Universal Transceiver when you sell your
car.
Metallic sun protection films should not be used on any windows in a car equipped with HomeLink® Universal
Transceiver. This could interfere with the transceiver's function.

Replacing fuses
If an electrical component fails to function, it is possible that a fuse has blown due to a temporary circuit overload.
Fuses are located in different places:
A - Relays/fuse box in the engine compartment
B - Fuse box in the passenger compartment
C - Relays/fuse box in the cargo area
A label on the inside of each cover indicates the amperage and the electrical components that are connected to each
fuse.
The easiest way to see if a fuse is blown is to remove it. Pull the fuse straight out. If a fuse is difficult to remove, you
will find a special fuse removal tool in the passenger compartment fuse box. From the side, examine the curved metal
wire to see if it is broken. If so, put in a new fuse of the same color and amperage (written on the fuse). Spare fuses
are stored in the fuse box in the passenger compartment. If fuses burn out repeatedly, have the electrical system
inspected by an authorized Volvo retailer.
WARNING!
Never use fuses with higher amperage that those stated on the following pages. Doing so could overload the car's
electrical system.
pg. 117 Fuses in the engine compartment
Relays/fuses in the engine compartment
When replacing fuses, be sure to replace a blown fuse with a new one of the same color and amperage (written on
the fuse). Fuse amperage is also indicated on the inside of the fuse box cover.
