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).
Deposit control gasoline  (detergent  additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be
effective in keeping injectors  and  intake  valves clean. Consistent use of deposit control gasolines will help ensure good
driveability and  fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with
the service station operator.
Unleaded fuel
Each Volvo has a  three-way catalytic converter and  must  use only unleaded gasoline. U.S. and  Canadian regulations
require that pumps delivering unleaded gasoline be  labelled "UNLEADED".  Only these pumps have nozzles which  fit
your car's filler  inlet. It is unlawful to dispense  leaded fuel into a  vehicle labelled "unleaded gasoline only". Leaded
gasoline damages the three-way catalytic converter and  the heated oxygen  sensor system. Repeated use of leaded
gasoline will lessen  the effectiveness of the emission control system and  could result in loss of emission warranty
coverage. State and  local  vehicle inspection programs will make detection of misfueling easier, possibly resulting in
emission test failure for misfueled  vehicles.
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
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates"  which  are usually alcohols or ethers. In some areas, state or
local  laws require that the service pump be  marked indicating use of alcohols or ethers. However, there are areas in
which  the pumps are unmarked. If you are not sure whether there is alcohol  or ethers in the gasoline you buy, check
with the service station operator. To meet  seasonal air quality standards, some areas require the use of "oxygenated"
fuel.
Volvo allows the use of the following "oxygenated" fuels; however,  the octane ratings listed on this  page must  still  be
met.
Alcohol - Ethanol: Fuels containing up to 10% ethanol  by volume may be  used. Ethanol may also be  referred to as
Ethyl alcohol,  or "Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be  used.
CAUTION!
Do not use gasolines containing methanol (methyl alcohol,  wood alcohol). This practice can result in vehicle
performance deterioration and  can damage critical parts  in the fuel system. Such damage may not be  covered under the
New Vehicle Limited Warranty.
pg. 73 Fuel  requirements
Carbon Monoxide - Important  Warning
Carbon  monoxide is a  poisonous, colorless, and  odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes  inside the vehicle, make sure the passenger  compartment is ventilated,  and  immediately return the
vehicle to your retailer for correction.
Fuel Formulations 
ProCarManuals.com 
Page 60 of 123
If you select the (MAN)ual position while driving, the gear that was being used in the (D)rive  position will also
initially be  selected in (MAN)ual position.
 Move the gear selector forward (toward "+") to shift to a  higher gear or rearward (toward "-") to shift to a  lower
gear.
 If you hold the gear selector toward "-", the transmission will downshift one  gear , and  will utilize the braking power
of the engine. If the current speed is too high for using a  lower gear, the downshift will not occur until the speed has
decreased  enough  to allow the lower gear to be  used.
 If you slow down to a  very low speed, the transmission will automatically  shift down.
 When starting in the (MAN)ual position, 3rd gear is the highest gear that may be  selected.
NOTE:  Kickdown (see previous  page) does not function  when the transmission is in the manual  shift (geartronic)
mode. The gear selector must  be  in D (Drive)  position.
* Models with a  5-cylinder turbo engine have a  5-speed transmission. Fifth  gear also has the lock-up function.
W Winter/Wet driving mode - enhanced vehicle  traction
 Mode W  will only function if the gear selector is in the (D)rive  position.
 Press the button at the base of the gear selector to engage/disengage this  driving mode. The position of this  button
may vary slightly  on certain models.
 An LED  in the button will light up to indicate that W is engaged and  this  will also be  displayed in the instrument
panel (see page 27
).
 This mode may be  selected for starting/moving off on slippery roads.
pg. 82 Four -C  active chassis system
Four-C (option)  
Your car can be  optionally equipped with the Four-C (Continuously Controlled Chassis Concept) system.
This system is based on a  number of sensors  that continuously monitor factors such as the car'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 adjustment of each shock absorber.  The system adjusts the stiffness of the shock
absorbers approximately 100 times per second.
The button in the center  console (see the illustration on page 31
) can be  used at any time  to switch between the two
driving modes: Comfort or Sport.
The system then adjusts the stiffness of the shock absorbers accordingly, for example when the type of road changes,
or if the driver wishes to change driving style. This adjustment takes place instantaneously.
Comfort  
ProCarManuals.com 
Page 61 of 123
The Comfort mode chassis setting offers the greatest amount of shock absorption and  the softest ride. This mode is
recommended for long-distance driving, or when driving in slippery conditions.
If Comfort mode was selected when the engine was switched off, this  mode will be  active when the engine is restarted.
Sport 
An indicator lamp in the button will come on when this  mode has been activated.
In Sport mode, shock absorption is stiffer to reduce the car's body sway during cornering and  to provide more
immediate steering response.
If this  setting was selected when the engine was switched off, Sport mode will be  active when the engine is restarted.
pg. 83 Front/rear park assist  (option/accessory)
A - front  (accessory as available), B - rear (option)
Front/rear park assist 
The park assist system(s) are designed to assist you when driving into parking spaces, garages, etc. They utilize
ultrasound sensors  located in the bumpers  to measure the distance to a  vehicle or other object,  or a  person who may be
close to the front  or rear of the vehicle.
When is park assist active? 
Front:  the system is active from  the time the engine is started until the car exceeds a  speed of approximately 10 mph
(15 km/h). 
Rear:  when the engine is running and  reverse  gear is selected.
NOTE:  
· If the vehicle is equipped with front  and  rear park assist, both systems will either be  activated or deactivated together.
They cannot be  used separately. 
· The indicator light in the button (see the illustration on page 31
) will light up to indicate that park assist system(s) are
activated.
When park assist is actively working:  
1. The audio system's volume will be  reduced. 
2. An intermittent signal will be  audible  from  the speakers  to indicate that you are approaching  a  person, object,
parked vehicle, etc.
The signals begin when the distance between the bumper and  the object  is:  
Rear:  approximately 5 feet (1.5 meters) 
Front:  approximately 2.5 ft (0.8 meters) 
3. At a  distance of approximately 1 foot (30 cm), the signal will become constant.
Deactivating the system(s)  
ProCarManuals.com 
Page 62 of 123
· Press the Park assist button on the center  console (see page 31) to temporarily deactivate the system(s). 
· The indicator light in the button will go out when the system(s) have been deactivated. 
· If the vehicle is equipped with front  and  rear park assist, both systems will be  deactivated by pressing the button.
NOTE: 
It may be  necessary  to deactivate one  or both of the park assist systems in certain cases. 
· Rear park assist:  towing a  trailer, carrying bicycles in a  rear-mounted carrier, etc, could trigger the rear park assist
system's sensors.  
· Front  park assist:  it may not be  possible to combine  auxiliary headlights and  front  park assist since these lights
could trigger the system's sensors.
Faults in the system  
If a  fault should occur in the system, the LED  in the button will be  switched off and  a  message will be  displayed in the
text window.
Cleaning the sensors
For the system to function properly, the sensors  in the front  and/or rear bumpers  should be  kept clean. They can be
cleaned with car washing detergent and  a  sponge.
WARNING!
These systems are designed to be  a  supplementary aid when parking the vehicle. They are not, however,  intended  to
replace  the driver's attention and  judgement.
pg. 84 Driving economy
Economical driving conserves natural resources  
Better  driving economy may be  obtained  by thinking ahead, avoiding rapid starts and  stops and  adjusting the speed of
your vehicle to immediate traffic  conditions. Observe the following rules:
 Bring the engine to normal operating temperature as soon as possible by driving with a  light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and  is subject to increased wear.
 Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
 Drive carefully and  avoid rapid acceleration and  hard braking.
 Do not exceed posted speed limits.
 Avoid carrying unnecessary  items (extra load) in the car.
 Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
 Remove snow tires when threat of snow or ice has ended.
 Note  that roof racks, ski racks, etc., increase air resistance  and  also fuel consumption.
 Avoid using automatic  transmission kickdown  feature unless necessary.
 Avoid using the air conditioning when it is not required. When engaged, the A/C compressor places an  additional
load on the engine. However, at higher driving speeds, fuel consumption will be  lower with the air conditioning on and
the windows closed than with the air conditioning off and  the windows open.
 Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease  gas mileage are:
 Dirty air cleaner
 Dirty engine oil and  clogged oil filter
 Dragging brakes
 Incorrect front  end  alignment
Some of the above mentioned items and  others  are checked at the standard Maintenance Service intervals.

Tire Pressure Monitoring System (TPMS)  - option on certain U.S. models only  
The tire pressure monitoring  system uses sensors  mounted in the tire valves to check inflation pressure levels. When
the vehicle is moving at a  speed of 20 mph (30 km/h) or faster, these sensors  transmit inflation pressure data to a
receiver located in the vehicle.
USA  - FCC ID: MRXTG315AM04
This device complies with part 15 of the FCC rules.  Operation is subject to the following conditions:  (1) This device
may not cause harmful interference, and  (2) this  device must  accept any  interference received,  including interference
that may cause undesired operation.
ProCarManuals.com 
Page 69 of 123
When low inflation pressure is detected, TPMS will light up the tire pressure warning light () in the instrument
panel, and  will display a  message in the text window. The wording of this  message is determined by the degree of
inflation pressure loss.
When the tire pressure monitoring  system warning light is on, one  or more of your tires is significantly under-inflated.
You should stop and  check your tires as soon as possible, and  inflate them to the proper pressure as indicated on the
vehicle's tire information placard.
Driving on a  significantly under-inflated tire causes the tire to overheat  and  can lead to tire failure. Under-inflation
also reduces fuel efficiency and  tire tread life, and  may affect the vehicle's handling and  stopping  ability. Each tire,
including the spare, should be  checked monthly when cold and  set to the recommended inflation pressure as specified
in the vehicle placard  and  owner's  manual.
NOTE:  TPMS indicates low tire pressure but does not replace  normal tire maintenance. For information on correct tire
pressure, please refer  to the table  on page 101
, or consult your Volvo retailer.
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 table  on page 101
).
3. Drive the car for at least one  minute 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 tires  
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, for example, winter wheels/tires are used that are not equipped with TPMS sensors,  the message TIRE PRESSURE
SYSTEM  SERVICE REQUIRED will be  displayed after the car has been driven for several minutes at approximately
35 mph (50 km/h) or faster. 
This message will remain on until wheels with TPMS sensors  are mounted on the vehicle and  it has been driven for at
least one  minute at a  speed of 20 mph (30 km/h) or faster. 
TPMS valves can be  fitted on winter wheels or full-size spare wheels/tires. Consult your Volvo retailer.
CAUTION!  
When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or
otherwise damaging  the valve.
