2008 VOLVO V70 engine overheat

If this light comes on while the vehicle is being driven, or remains on for longer than approximately 10 seconds after
the vehicle has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or
pretensioner, a front airbag, side impact airbag, and/or an inflatable curtain. Have the system(s) inspected by a trained
and qualified Volvo service technician as soon as possible.
Seat belt reminder
This symbol comes on for approximately 6 seconds if the driver has not fastened his or her seat belt.
Generator not charging
This symbol comes on during driving if a fault has occurred in the electrical system. Contact an authorized Volvo
workshop.
Engine temperature
Engine overheating can result from low oil or coolant levels, towing or hard driving at high heat and altitude, or
mechanical malfunction. Engine overheating will be signaled with text and a red warning triangle in the middle of the
instrument display. The exact text will depend on the degree of overheating. It may range from " HIGH ENGINE
TEMP - SLOW DOWN " to "HIGH ENGINE TEMP - STOP ENGINE ." If appropriate, other messages, such as
" COOLANT LEVEL LOW " will also be displayed. If your engine does overheat so that you must stop the engine,
always allow the engine to cool before attempting to check oil and coolant levels.
Fault in brake system
If this symbol lights, the brake fluid level may be too low. Stop the vehicle in a safe place and check the level in the
brake fluid reservoir, see page 223
. If the level in the reservoir is below MIN , the vehicle should be transported to an
authorized Volvo workshop to have the brake system checked.
If the brake and ABS symbols come on at the same time, there may be a fault in the brake force distribution system.
1. Stop the vehicle in a safe place and turn off the engine.
2. Restart the engine.
If both symbols extinguish, continue driving.
If the symbols remain on, check the level in the brake fluid reservoir. See page 223. If the brake fluid level is
normal but the symbols are still lit, the vehicle can be driven, with great care, to an authorized Volvo workshop to
have the brake system checked.
If the level in the reservoir is below MIN , the vehicle should be transported to an authorized Volvo workshop to
have the brake system checked.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a warning message is displayed in the text window:
DO NOT DRIVE. Have the vehicle towed to an authorized Volvo retailer and have the brake system inspected.
If the ABS and Brake system lights are on at the same time, there is a risk of reduced vehicle stability.

WARNING
An extra mat on the driver's floor can cause the accelerator and/or brake 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.
4. Press and release the START/STOP ENGINE button. The autostart function will operate the starter motor until the
engine starts.
The starter motor operates for a maximum of 10 seconds. If the engine has not started, repeat the procedure.
1On vehicles with the optional keyless drive, it is only necessary to have a remote control in the passenger's compartment.
2 If the vehicle is moving, it is only necessary to press the START/STOP ENGINE button to start the vehicle.
WARNING
Always remove the remote key from the ignition slot when leaving the vehicle, especially if there are children in
the vehicle.
Never remove the remote key from the ignition slot while driving or when the vehicle is being towed. The
steering lock could otherwise be activated, making it impossible to steer the vehicle. Never remove the remote key
with keyless drive function (option) from the vehicle while driving or during towing.
Always place the gear selector in Park and apply the parking brake before leaving the vehicle. Never leave the
vehicle unattended with the engine running.
Always open garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The
exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.
110 03 Your driving environment
Starting the engine
NOTE
The idling speed can be noticeably higher than normal during cold starts. This is to enable emission control system
can reach normal operating temperature as quickly as possible, which helps reduce exhaust emissions
1.
Keylock: Your vehicle is equipped with a keylock system. When the engine is switched off, the gear selector must
be in the Park position before the key can be removed
2 from the ignition slot.
1If the gear selector is in the D or R positions and the car is not moving, engine speed (rpm) will be lower and it will take longer for the engine to
reach normal operating temperature.
2Does not apply to vehicles with the optional keyless drive.
CAUTION
When starting in cold weather, the automatic transmission may shift up at slightly higher engine speeds than
normal until the automatic transmission fluid reaches normal operating temperature.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough
to prevent engine damage.
The engine should be idling when you move the gear selector. Never accelerate until after you feel the
transmission engage. Accelerating immediately after selecting a gear will cause harsh engagement and premature
transmission wear.
Selecting P or N when idling at a standstill for prolonged periods of time will help prevent overheating of the
ProCarManuals.com

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
transmission. 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 vehicle is in water, do not attempt to restart it. Have the vehicle towed
out of the water.
Engine and cooling system
Under special conditions, for example when driving in hilly terrain, extreme heat or with heavy loads, there is a risk
that the engine and cooling system will overheat. Proceed as follows to avoid overheating the engine.
Maintain a low speed when driving with a trailer up long, steep hills.
Do not turn the engine off immediately when stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.
Remove any auxiliary lights from in front of the grille when driving in hot weather conditions.
Do not exceed engine speeds of 4500 rpm if driving with a trailer in hilly terrain. The oil temperature could become
too high.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid using ignition mode II . Many electrical systems (the audio system, the
optional navigation system, power windows, etc) will function in ignition modes 0 and I . These modes reduce drain on
the battery.
Please keep in mind that using systems, accessories, etc., that consume a great deal of current when the engine is not
running could result in the battery being completely drained.
The optional 12 volt socket in the cargo area provides electrical current even with the ignition switched off, which
drains the battery.

Driving recommendations
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before
driving long distances. Your retailer will also be able to supply you with bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be checked before any long trip:
Check that engine runs smoothly and that fuel consumption is normal.
Check for fuel, oil, and fluid leakage
Have the transmission oil level checked.
ProCarManuals.com

CAUTION
Do not refuel with the engine running1. Turn the ignition off or to position I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
Avoid overfilling the fuel tank. Do not press the handle on the filler nozzle more than one extra time. Too much
fuel in the tank in hot weather conditions can cause the fuel to overflow. Overfilling could also cause damage to the
emission control systems.
1If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator
lamp) may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo original or approved fuel filler caps.
Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical, fuel or
distributor ignition systems, may cause unusually high three-way catalytic converter temperatures. Do not continue to
operate your vehicle if you detect engine misfire, noticeable loss of power or other unusual operating conditions, such
as engine overheating or backfiring. A properly tuned engine will help avoid malfunctions that could damage the three-
way catalytic converter.
Do not park your vehicle over combustible materials, such as grass or leaves, which can come into contact with the
hot exhaust system and cause such materials to ignite under certain wind and weather conditions.
Excessive starter cranking (in excess of one minute), or an intermittently firing or flooded engine can cause three-
way catalytic converter or exhaust system overheating.
Remember that tampering or unauthorized modifications to the engine, the Engine Control Module, or the vehicle
may be illegal and can cause three-way catalytic converter or exhaust system overheating. This includes: altering fuel
injection settings
201 05 During your trip
Refueling
or components, altering emission system components or location or removing components, and/or repeated use of
leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensors
The heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fed into a control module
that continuously monitors engine functions and controls fuel injection. The ratio of fuel to air into the engine is
continuously adjusted for efficient combustion to help reduce harmful emissions.
202 05 During your trip
Loading
Introduction
The load carrying capacity of your vehicle is determined by factors such as the number of passengers, the amount of
ProCarManuals.com

Load carriers are available as Volvo accessories. Observe the following points when in use:
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 vehicle.
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.
Secure the cargo correctly with appropriate tie-down equipment.
Check periodically that the load carriers and load are properly secured.
Remember that the vehicle's center of gravity and handling change when you carry a load on the roof.
212 05 During your trip
Cargo area
The vehicle's wind resistance and fuel consumption will increase with the size of the load.
Drive smoothly. Avoid rapid starts, fast cornering and hard braking.
213 05 During your trip
Towing a trailer
Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
NOTE
See page 274
for the maximum trailer and tongue weights recommended by Volvo.
Observe the legal requirements of the state/province in which the vehicles are
All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailer hitch installation should
not interfere with the proper operation of this bumper system.
Trailer towing does not normally present any particular problems, but take into consideration:
Increase tire pressure to recommended full. See the tire inflation tables on pages 250 and 251.
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km).
Maximum speed when towing a trailer: 50 mph (80 km/h).
Engine and transmission are subject to increased loads. Therefore, engine coolant temperature should be closely
watched when driving in hot climates or hilly terrain. Use a lower gear and turn off the air conditioner if the
temperature gauge needle enters the red range.
If the automatic transmission begins to overheat, a message will be displayed in the text window.
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability, and economy.
It is necessary to balance trailer brakes with the towing vehicle brakes to provide a safe stop (check and observe
state/local regulations).
Do not connect the trailer's brake system directly to the vehicle's brake system.
