Keys  
Two keys are provided with your car; a  master key  and  a  service key.  The master key,  the remote control, and  the
central locking button may all be  used to lock and  unlock all of your car's locks.
The service key  will operate  only the driver's door and  the ignition switch. It is intended  to help deter unwanted entry
into the glove compartment and  trunk.
Turn the key once  to unlock the driver's door only.
Turn the key again (within 10 seconds)  to unlock all doors and  the trunk.
One turn with the key  towards lock in the drivers door locks all doors, trunk.

Use the switch on the front  door armrests to lock/unlock the car from  the inside.WARNING!
If the doors are locked while driving, this  may hinder rapid access to the occupants of the car in the event of an
accident. (Also see information on "Child  safety locks").
Note:  To help prevent accidentally locking the keys in the car, the central locking system is designed to unlock the
doors immediately if the key  is left in the ignition switch, the car is locked using the lock button on the door and  the
door is then closed.  A sound from the lock will be audible at this time.  
Please note that this  function will  not unlock the doors if the engine is running.
Immobilizer (start inhibitor) 
Each of the keys supplied with your car contains a  coded transmitter. The code in the key  is transmitted to an  antenna
in the ignition switch where  it is compared  to the code stored  in the start inhibitor  module. The car will start only with
a  properly coded key.
If you misplace a  key,  take the other keys to an  authorized Volvo retailer for reprogramming as an  antitheft measure.
This device complies with part 15 of the FCC rules.  Operation is subject to the following condition: (1) This device

R (Reverse) 
Never  engage R while the car is moving forward.
N (Neutral)  
Neutral - no gear engaged. Use the parking brake.
D (Drive)  
D is the normal driving position and  should be  used as often as possible to help improve fuel economy. The car should
not be  moving when shifting from  R to the D position.
3 (Intermediate  gear)  
The transmission will shift automatically  between gears 3, 2 or 1 from  this  position. The transmission  cannot shift up
to (D)rive from third gear.
2 (Intermediate  gear)  
The transmission will shift automatically  between gears 2 and  1 from  this  position. The transmission  cannot shift up
to third gear from second gear.
1 (Low gear)  
If you select this  gear at speeds above 30 mph (50 km/h), the transmission will first shift to second gear and  then to
first gear at lower speeds.
NOTE:  The intermediate and  low gears can be  used for:
Driving in a  mountainous area
Towing a  trailer
Increasing the braking effect of the engine.
The transmission has a  built-in limiter designed to help prevent excessive engine speeds (high rpm)  when gears 3, 2
or 1 are selected.
Kickdown
Automatic shift to a  lower gear (kickdown) is achieved by depressing the accelerator  pedal fully and  briskly. An
upshift will occur when approaching  the top speed for a  particular gear or by releasing the accelerator  pedal slightly.
Kickdown can be  used for maximum acceleration or when passing at highway  speeds.
Automatic transmission  - adaptive system  
The automatic  transmission is controlled by an  adaptive control system that constantly monitors the way in which  the
transmission functions. It senses and  adapts each gear shift for optimal performance. The system also monitors your
particular driving style and  adapts gear shifting accordingly.
pg. 75 Automatic transmission
ProCarManuals.com 

Manual shifting - Geartronic 
You can move the gear selector freely between the (MAN) ual and  (D)rive positions while driving. Gears 2, 3, and  4
have a  "lock -up" function which  reduces engine speed and  helps save fuel. 
The currently selected gear will be  displayed in the instrument panel (see page 25
).
 To access the (MAN)ual shifting position from  (D)rive,  pull the gear selector back slightly  from  D and  move it to
the left to MAN.
 To return to the (D)rive  position from  MAN, move the gear selector to the right and  push it forward to the (D)rive
position.
While driving  
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.
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 (see illustration).
 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 25
).
 This mode may be  selected for starting/moving off on slippery roads.
pg. 78 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.
ProCarManuals.com 

The button in the center  console (see the illustration on page 29) 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  
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. 79 Rear parking assistance (option)
Rear Parking  Assistance  
This system is used to assist you when backing into parking spaces, etc by providing an  audible  tone as you back up.
The system is automatically  activated when you select reverse  gear.
It utilizes ultrasound sensors  located in the rear bumper to measure the distance to a  vehicle or other object,  or a
person who may be  behind the vehicle.
When the system is active:  
1. The audio system's volume will be  reduced.
2. An intermittent signal will be  audible  from  the audio system's speakers  to indicate that as you back up, you are
approaching  a  person, object,  parked vehicle, etc. The signals begin when the vehicle is at a  distance of approximately
5 feet (1.5 meters) from  an  object/person, etc.
3. At a  distance of approximately 1 foot (30 cm), the signal will become constant.
Switching off the system
Towing a  trailer, carrying bicycles in a  tailgate -mounted carrier, etc, could trigger the reverse  warning system.

"kickdown"  to help improve fuel economy.
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 Park. Do not stop the engine!
 Switch the heater  to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
 If the warning light in the center  of the instrument panel is red, and  the message "Coolant level  lo stop engine"  is
displayed, switch off the engine as soon as possible.
WARNING!
Do not remove coolant  expansion tank cap. The coolant  will be  extremely hot.
If necessary,  see page 118
 for information on checking and  topping-up the coolant  level.
