2006 VOLVO XC70 check engine light

General information
Important
Before you operate your car for the first time, please familiarize
yourself with the new-engine oil consumption information on page
160. You should also be familiar with the information in chapters
one, two and four of this manual.
Information contained in the balance of the manual is extremely
useful and should be read after operating the vehicle for the first
time.
The manual is structured so that it can be used for reference. For
this reason, it should be kept in the car for ready access.
Do not export your Volvo to another country before investigating
that country’s applicable safety and exhaust emission requirements.
In some cases it may be difficult or impossible to comply with these
requirements. Modifications to the emission control system(s) may
render your Volvo not certifiable for legal operation in the U.S.,
Canada and other countries.
All information, illustrations and specifications contained in this
manual are based on the latest product information available at the
time of publication. Please note that some vehicles may be equipped
differently, depending on special legal requirements and that
optional equipment described in this manual may not be available in
all markets.
Volvo reserves the right to make model changes at any time, or to
change specifications or design, without notice and without
incurring obligation.
CALIFORNIA Proposition 65 Warning
WARNING! Engine exhaust, some of its constituents, and certain
vehicle components contain or emit chemicals known to the state of
California to cause cancer, and birth defects or other reproductive
harm. In addition, certain fluids contained in vehicles and certain
products of component wear contain or emit chemicals known to the
State of California to cause cancer, and birth defects or other
reproductive harm.
Shiftlock
When your car is parked, the gear selector is locked in the (P)ark
position. To release the selector from this position, turn the ignition key
to position II (or start the engine), depress the brake pedal, press the
button on the front of the gear selector knob and move the selector from
(P)ark.
Keylock
This means that when you switch off the ignition, the gear selector must
be in the (P)ark position before the key can be removed from the
ignition switch.
Anti-lock Brake System (ABS)
The ABS system in your car performs a self-diagnostic test when the
vehicle first reaches the speed of approximately 12 mph (20 km/h). The
brake pedal will pulsate several times and a sound may be audible from
the ABS control module. This is normal.
Fuel filler door
Press the button on the light switch panel (see page 35) when the car is at
a standstill to unlock the fuel filler door. Please note that the fuel filler
door will remain unlocked until the car begins to move forward.
An audible click will be heard when the fuel filler door relocks.
Fuel filler cap
After refueling, close the fuel filler cap by turning it clockwise until it
clicks into place. If this cap is not closed tightly or if the engine is
running when the car is refueled, the Malfunction Indicator Lamp
(“Check Engine” light) may indicate a fault.
WARNING! If your vehicle is involved in an accident, unseen damage
may affect your vehicle's driveability and safety.

pulsation, which is normal.
10 Gear and driving mode indicator
The currently selected driving mode is
displayed here. If you use the Geartronic
function on the automatic transmission, the
currently selected gear will be displayed.
11 Ambient temperature indicator
This display indicates the air temperature
outside your car. A "snowflake" symbol in the
text window is displayed when the temperature
is in the range of 23 - 36° F (-5 - +2° C).

On-Board Diagnostics II (OBDII): As you
drive, a computer called “OBDII” monitors
your car’s engine, transmission, electrical and
emission systems. The CHECK ENGINE
light will light up if the computer senses a
condition that potentially may need correcting.
When this happens, please have your car
checked by a Volvo retailer as soon as
possible.

Octane rating: Volvo engines are designed for optimum performance
on unleaded premium gasoline with an octane rating AKI of 91, or
above. AKI (ANTI KNOCK INDEX) is an average of the Research
Octane Number, RON, and the Motor Octane Number, MON. (RON +
MON/2). The minimum octane requirement is AKI 87 (RON 91).

NOTE: Some U.S. and Canadian gasolines contain an octane enhancing
additive called methyl-cyclopentadienyl manganese tricarbonyl (MMT).
If such fuels are used, your Emission Control System performance may
be affected, and the Check Engine light (malfunction indicator lamp)
located on your instrument panel may light. If this occurs, please return
your vehicle to an authorized Volvo retailer for service.Gasoline containing alcohol and ethers

Do not use gasolines containing methanol (methyl alcohol, wood
alcohol). This practice can result in vehicle performance deteriora-
tion and can damage critical parts in the fuel system. Such damage
may not be covered under the New Vehicle Limited Warranty.

Emergency towing
Front towing eyelet Rear towing eyelet
Emergency towing
The towing eyelet is located in the tool bag,
under the floor of the cargo area, with the
spare tire. This eyelet must be screwed into the
positions provided on the right sides of either
the front or rear bumper (see illustration). To
attach the towing eyelet:

After the car has been towed, the eyelet should
be removed and returned to the tool bag. Press
the cover back into position.

CAUTION:
•Please check with state and local authori-
ties 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, etc.
•If the car’s battery is dead, do not attempt
to start the vehicle by pushing or pulling it
as this will damage the three-way catalytic
converter(s). The engine must be jump
started using an auxiliary battery (see page
109).
•If the car is being towed on a flat bed
truck, the towing eyelets must not be used
to secure the car on the flat bed. Consult
the tow truck operator.
WARNING!
•Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but the
brake pedal pressure required is 3 - 4
times above normal and greater steering
effort must be exerted.
•The towing eyelets must not be used for
pulling another vehicle out of a ditch or
for any similar purpose involving severe
strain.
•Do not use the towing eyelets to pull the
car up onto a flat bed tow truck.

Water on brake discs and brake pads affects
braking
Driving in rain and slush or passing through an automatic car wash can
cause water to collect on the brake discs and pads. This will cause a
delay in braking effect when the pedal is depressed. To avoid such a
delay when the brakes are needed, depress the pedal occasionally when
driving through rain, slush etc. This will remove the water from the
brakes. Check that brake application feels normal. This should also be
done after washing or starting in very damp or cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or
hilly areas or towing. Vehicle speed is usually slower, which means that
the cooling of the brakes is less efficient than when driving on level
roads. To reduce the strain on the brakes, shift into a lower gear and let
the engine help with the braking. Do not forget that, if you are towing a
trailer, the brakes will be subjected to a greater than normal load.

NOTE: When the car is at a standstill and the engine is idling, e.g. at a
traffic light and the brake pedal is depressed, the pedal may go down
slightly. This is normal and is caused by an built-in function in the
power brake system.
Power brakes function only when the engine

CAUTION!
•Not checking the oil level regularly can
result in serious engine damage if the oil
level becomes too low.
•Oil that is lower than the specified quality
can damage the engine.
•Always add oil of the same type and
viscosity as already used.
•Never fill oil above the MAX mark. This
could cause an increase in oil consump-
tion.
R-models
R-models are equipped with an oil level
warning system. If the engine oil level
becomes too low, the warning light in the
instrument panel will come on and a warning
will be displayed in the text window.
