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.

Brakes

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.

Electric parking brake
An electric parking brake has the same func-
tion as a manual parking brake.
NOTE
•A faint sound from the parking brake's
electric motor can be heard when the
parking brake is being applied. This
sound can also be heard during the
automatic function check of the parking
brake.
•The brake pedal will move slightly when
the electric parking brake is applied or
released.
Low battery voltageIf the battery voltage is too low, the parking
brake cannot be applied or released. Connect
an auxiliary battery if the battery voltage is too
low, see page 109.

Introduction
Distance Alert is part of Adaptive Cruise Con-
trol and is a function that provides information
about the time interval to the vehicle ahead.
Time interval information is only given for a
vehicle that is driving ahead of your vehicle, in
the same lane, and in the same direction. No
information is provided for vehicles driving
toward you, moving very slowly, or at a stand-
still.
G017362
A smaller section of the red warning light in the
windshield glows steadily if your vehicle is
closer to the vehicle ahead than the set time
interval.
NOTE
Distance Alert is in active mode while Adap-
tive Cruise Control is active.
Distance Alert is active at speeds above
approximately 20 mph (30 km/h).
WARNING
Distance Alert only indicates the distance to
the vehicle ahead. It does not affect the
speed of your vehicle.

Visual indicatorThe audio system’s display gives an overview
of the vehicle’s position in relation to a
detected object.
The markers in the display indicate that one or
more of the four sensors has detected an
object. The greater the number of markers, the
closer the vehicle is to the object.

only. Here, an object has been detected by
both of the right rear sensors.
Display in a vehicle with both front and rear
park assist. The solid marker in this example
indicates that an object is closer than approx-
imately 1 foot (30 cm) to the right front sensor.
Display in a vehicle with both front and rear
park assist. Reverse gear is selected and no
objects have been detected in front of or
behind the vehicle.
Audible signalThe Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
in front of or behind the vehicle (example 2 in
the illustration). If there are objects within this
distance both behind and in front of the vehicle,
the tone alternates between front and rear
speakers.
If the volume of another source from the audio
system is high, this will be automatically low-
ered.
Rear park assist
G021423
The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The audible signal
comes from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc, which could trigger the rear park
assist system's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.
