CAUTION
•When starting in cold weather, the auto-
matic transmission may shift up at
slightly higher engine speeds than nor-
mal until the automatic transmission
fluid reaches normal operating tem-
perature.
•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 acceler-
ate until after you feel the transmission
engage. Accelerating immediately after
selecting a gear will cause harsh
engagement and premature transmis-
sion wear.
•Selecting P or N when idling at a stand-
still for prolonged periods of time will
help prevent overheating of the auto-
matic transmission fluid.
Switching off the engine
With the engine running, press the START/
STOP ENGINE button.
If the gear selector is not in the P position or if
the vehicle is moving, press the button twice or
press and hold it in until the engine switches
off.

Connecting the jumper cables
Follow these instructions to jump start your
vehicle's dead battery or to jump start another
vehicle's dead battery using your vehicle. If the
12-volt auxiliary battery to be used is in another
vehicle, check that the vehicles are not touch-
ing to prevent premature completion of a cir-
cuit. Be sure to follow jump starting instruc-
tions provided for the other vehicle.To jump start your vehicle:
1. Switch off the ignition (set the ignition to
mode 0, see page 80).
2. First connect the red jumper cable to the
auxiliary battery's positive (+) terminal
.
3. Fold back the cover over the positive (+)
terminal on your vehicle's battery
,
marked with a "+" sign, located under a
folding cover.
4. Connect the black jumper cable to the aux-
iliary battery's negative (–) terminal
and
to the ground point in your vehicle's engine
compartment (right engine mount at the
top, on the outer screw)
.
5. Start the engine in the assisting vehicle,
then start the engine in the vehicle with
dead battery.
6. After the engine has started, first remove
the negative (–) terminal jumper cable
(black). Then remove the positive (+) termi-
nal jumper cable (red).

Shiftgate positions1
Depress the button on the front of the gear
selector knob to move the gear selector
between the R, N, D, and P positions.
The gear selector can be moved freely between
the Geartronic (manual shifting) and Drive (D)
positions while driving.
Park position (P)Select the P position when starting or parking.
KeylockTo remove the remote key from the ignition
slot, the gear selector must be in the P position.
The remote key is locked in the slot in all other
positions.
ShiftlockWhen P has been selected, the transmission is
mechanically blocked in this position. The
brake pedal must be depressed before the
gear lever can be moved from the P position.
Always apply the parking brake when the vehi-
cle is parked, see page 116. If the vehicle is
equipped with the optional electric parking
brake, press the control to apply the brake, see
page 116.
G021350
CAUTION
The vehicle must be stationary when posi-
tion P is selected.
Reverse (R)The vehicle must be stationary when position
R is selected.
Neutral position (N)No gear is engaged and the engine can be
started with the gear selector in this position.
Apply the parking brake if the vehicle is sta-
tionary with the gear selector in position N.
Drive (D)D is the normal driving position. The car auto-
matically shifts between the various forward
gears, based on the level of acceleration and
speed. The car must be at a standstill when
shifting from position R to position D.
Geartronic–manual shiftingGeartronic allows you to manually shift among
your vehicle's six forward speeds. Geartronic
can be selected at any time.
•To access the manual shifting position
from Drive (D), move the gear selector to
the right (to the area marked M in the illus-
tration or to S on models equipped with
Sport mode).
1The information display (see page 73) shows the gear selector's position or the selected gear by displaying the following: P, R, N, D, S, 1, 2, 3, 4, 5, or 6.

NOTE
On models equipped with Sport mode, the
transmission will not switch to manual shift-
ing mode until the gear selector is moved
forward or rearward. The selected gear will
then be shown in the information display
(see page 73).
•To return to the D position from the manual
shifting position or Sport mode, move the
gear selector to the left.
While driving
•If you select the manual shifting position
while driving, the gear that was being used
in the Drive position will also initially be
selected in the manual shifting 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 at a
time 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 to a very low speed, the trans-
mission will automatically shift down.
Shiftlock – Neutral (N)If the gear selector is in the N position and the
vehicle has been stationary for at least 3 sec-
onds (irrespective of whether the engine is run-
ning) then the gear selector is locked.
To be able to move the gear selector from N to
another gear position, the brake pedal must be
depressed and the ignition must be in posi-
tion II, see page 80.
Geartronic–starting on slippery surfacesSelecting 3rd gear in Geartronic’s manual shift-
ing mode can help provide better traction when
starting off on slippery surfaces. To do so:
1. Depress the brake pedal and move the
gear selector to the right from the D posi-
tion to the manual shifting position. The
text in the instrument panel display will
change from
D to 1.
2. Press the gear selector forward and
release it (this selects 2nd gear). Press the
selector forward again and release it to
select 3rd gear.
3. Release the brake pedal and press gently
on the accelerator pedal.
Shiftlock override
If the vehicle cannot be driven, for example
because of a dead battery, the gear selector
must be moved from the P position before the
vehicle can be moved
2.
Lift away the rubber mat on the floor of the
storage compartment behind the center
console to expose the small opening for
overriding the shiftlock system.
Insert the key blade into the opening. Press
the key blade down as far as possible and
keep it held down. Move the gear selector
from the P position. For information on the
key blade, see page 57.
2If the battery is dead, the electric parking brake cannot be applied or released. Connect an auxiliary battery if the battery voltage is too low, see page 109.

Please be aware that overriding the shiftlock
system does not release the steering wheel
lock.
All Wheel Drive – AWD3
Your Volvo can be equipped with permanent
All Wheel Drive, which means that power is
distributed automatically between the front
and rear wheels. Under normal driving condi-
tions, most of the engine's power is directed to
the front wheels. However, if there is any ten-
dency for the front wheels to spin, an electron-
ically controlled coupling distributes power to
the wheels that have the best traction.
NOTE
The message AWD disabled Service
required will be appear in the information
display if an electrical fault should occur in
the AWD system. A warning light will also
illuminate in the instrument panel. If this
occurs, have the system checked by a
trained and qualified Volvo service techni-
cian.
3Standard on certain models.

Brakes

114
Brake system
The brake system is a hydraulic system con-
sisting of two separate brake circuits. If a prob-
lem should occur in one of these circuits, it is
still possible to stop the vehicle with the other
brake circuit.
If the brake pedal must be depressed farther
than normal and requires greater foot pressure,
the stopping distance will be longer.
A warning light in the instrument panel will light
up to warn the driver that a fault has occurred.
If this light comes on while driving or braking,
stop immediately and check the brake fluid
level in the reservoir.
NOTE
Press the brake pedal hard and maintain
pressure on the pedal – do not pump the
brakes.
WARNING
If the fluid level is below the MIN mark in the
reservoir or if a brake system message is
shown in the information display:
DO NOT
DRIVE. Have the vehicle towed to a trained
and qualified Volvo service technician and
have the brake system inspected.
Power brakes function only when the
engine is running
The power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. Never let the vehicle roll to a stop with the
engine switched off.
If the power brakes are not working, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-
ple when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The
brake pedal feels harder than usual.
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 occa-
sionally 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 systemThe brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. Vehicle speed is usuallyslower, 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.
Anti-lock braking systemThe Anti-lock Braking System (ABS) helps to
improve vehicle control (stopping and steering)
during severe braking conditions by limiting
brake lockup. When the system "senses"
impending lockup, braking pressure is auto-
matically modulated in order to help prevent
lockup that could lead to a skid.
The system performs a brief self-diagnostic
test when the engine has been started and
driver releases the brake pedal. Another auto-
matic test may be performed when the vehicle
first reaches a speed of approximately 25 mph
(40 km/h). The brake pedal will pulsate several
times and a sound may be audible from the
ABS control module. This is normal.
Cleaning the brake discsCoatings of dirt and water on the brake discs
may result in delayed brake function. This delay
is minimized by cleaning the brake linings.
Cleaning the brake pads is advisable in wet
weather, prior to long-term parking, and after
the vehicle has been washed. Do this by brak-

ing gently for a short period while the vehicle is
moving.
Emergency Brake AssistanceEBA is designed to provide full brake effect
immediately in the event of sudden, hard brak-
ing. The system is activated by the speed with
which the brake pedal is depressed.
When the EBA system is activated, the brake
pedal will go down and pressure in the brake
system immediately increases to the maximum
level. Maintain full pressure on the brake pedal
in order to utilize the system completely. EBA
is automatically deactivated when the brake
pedal is released.
NOTE
•When the EBA system is activated, the
brake pedal will go down and pressure
in the brake system immediately increa-
ses to the maximum level. You must
maintain full pressure on the brake
pedal in order to utilize the system com-
pletely. There will be no braking effect if
the pedal is released. EBA is automati-
cally deactivated when the brake pedal
is released.
•When the vehicle has been parked for
some time, the brake pedal may sink
more than usual when the engine is
started. This is normal and the pedal will
return to its usual position when it is
released.
