Depress the button on the front of the gear
selector knob to move the 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.
Gear selector positions
P – ParkSelect the P position when starting or parking.
In P, the transmission is mechanically blocked
(Shiftlock). Always apply the parking brake
when parking.

D - left position: automatic shifting, M - right posi-
tion: manual shifting
CAUTION
The car must be stationary when selecting
position P.
R – ReverseThe car must be stationary when shifting to
position R.
N – NeutralN is the neutral position. The engine can be
started, but no gear is selected. Apply the park-
ing brake when the car is stationary with the
gear selector in N.
NOTE
If the gear selector is in the Neutral position
and the vehicle has been at a standstill for
at least 3 seconds, the brake pedal must be
pressed before the gear selector can be
moved to another position.
In order to move the gear selector to another
position:
1.
Turn the ignition key to position II (if the
engine is not already running).
2. Depress the brake pedal.
3. Move the gear selector to the desired posi-
tion.
D – DriveD is the normal driving position. The Drive posi-
tion offers 5 forward gears1. The car automat-
ically shifts between the various forward gears,
1T5 models have 6 forward gears.

based on the level of acceleration and speed.
The car must be at a standstill when shifting to
position D from position R.
Manual shifting – Geartronic
The manual shifting mode (Geartronic) can be
selected at any time to manually select forward
gears, including while the car is moving.
NOTE
Reverse, Neutral, and Park cannot be
selected in Geartronic mode.
•To access the Manual (M) shifting position
from Drive (D), move the gear selector to
the right to M.
•To return to the Drive (D) position from M,
move the gear selector to the left.
While driving
•If you select the M position while driving,
the gear that was being used in the Drive
position will also initially be selected in the
M 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 atime 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.
Cold starts (turbo engines)
When driving before the engine has reached its
normal operating temperature, the transmis-
sion will shift up at slightly higher engine
speeds to heat the three-way catalytic con-
verter as quickly as possible.
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 acceler-
ation or when passing at highway speeds.
Safety functionTo help prevent excessive engine speeds (rpm)
that could lead to engine damage, the engine
management system includes a function that
prevents kickdown from taking place if the
engine speed is too high.Kickdown will not occur if the driver attempts
to use this function when engine speeds are
too high. The transmission will remain in the
currently selected gear.

06 Starting and driving
All Wheel Drive*
06
154* Option/accessory, for more information, see Introduction.
All Wheel Drive (AWD) – general
information
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.
Tire dimensions
Volvo recommends that you always drive on
tires of the same brand, size, construction
(radial), tread pattern, load, speed, traction,
temperature, and treadwear rating. Never drive
on mixed tires, except for brief periods when
the temporary spare tire is in use.
Always use properly inflated tires of correct
dimensions. Tire size and inflation pressures
are shown on a placard located on the driver's
side B-pillar (the structural member at the side
of the vehicle, at the rear of the driver's door
opening). See also page 181 for the tire infla-
tion pressure tables beginning, .
Temporary Spare
The temporary spare tire is for temporary, low-
speed, short-distance use only. Replace it with
a full-sized tire as soon as possible. Do not
drive on the temporary spare at speeds above
50 mph (80 km/h).
Never install snow chains on a temporary
spare.

06 Starting and driving
Brake system
06

155 Brake circuit malfunction
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 Volvo
retailer and have the brake system inspec-
ted.
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 system
The brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. 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.
Anti-lock brakes (ABS)
The 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 self-diagnostic test
when the engine is started and when the
vehicle first reaches a speed of approxi-
mately 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.

06 Starting and driving
Brake system

156
For optimal ABS braking effect:1. Press down on the brake pedal with full
force. The pedal will pulsate.
2. Steer the vehicle in the direction of travel
and keep the brake pedal depressed.
Electronic Brake Force Distribution
(EBD)
EBD is an integrated part of the ABS system.
EBD regulates the hydraulic pressure to the
rear brakes to help provide optimal braking
capacity.
The switching of the ABS modulator will be
audible and the brake pedal will pulsate during
braking. Please be aware that ABS does not
increase the absolute braking potential of the
vehicle. While control will be enhanced, ABS
will not shorten stopping distances on slippery
surfaces.
If the warning lamp lights up there is a mal-
function of the ABS system (the standard brak-
ing system will still function) and the vehicle
should be driven cautiously to a trained and
qualified Volvo service technician for inspec-
tion.
WARNING
If the BRAKES and ABS warning symbols
light at the same time, there may be a prob-
lem in the brake system. If the brake fluid
level is normal in these circumstances, drive
carefully to a trained and qualified Volvo
service technician to have the brake system
checked.
Emergency Brake Assistance – EBAEBA 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.

157 Stability Traction Control (STC)/
Dynamic Stability Traction Control
(DSTC)
The stability system consists of a number of
functions designed help reduce wheel spin,
counteract skidding, and to generally help
improve directional stability.
A pulsating sound will be audible when the
system is actively operating and is normal.

NOTE
•The message STC/DSTC SPIN
CONTROL OFF indicates that the sta-
bility system's spin control function has
temporarily been switched off.
•The stability control indicator light
will illuminate and remain on until spin
control has been reactivated.
•The spin control function is automati-
cally enabled each time the engine is
started.
•STC/DSTC ON indicates that all sys-
tem functions are active.
Active yaw control – AYC (DSTC only)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.
1Models equipped with All Wheel Drive (AWD) have an integrated traction control function that cannot be disabled. DSTC is optional on AWD models.

Symbols used by the stability system
Stability system indicator light
Information symbol
If the and symbols light up at the same
time, read the message in the display.
If only the
symbol lights up, this indicates
one of the following situations:
•The light illuminates for approximately
2 seconds to indicate that the system is
performing a self-diagnostic test when the
engine is started.
•If the light flashes while driving, this indi-
cates that the stability system is actively
functioning to help counteract wheel spin
and/or a skid.
•If this light stays on after the engine has
started or comes on while driving, there
may be a fault in the stability system. Con-
sult a trained and qualified Volvo service
technician.
•If Spin control has been intentionally
switched off, a message is displayed and
the light will stay on as a reminder that this
function has been disabled by the driver.
WARNING
The stability system is intended to help
improve driving safety. It supplements, but
can never replace, the driver's judgement
and responsibility when operating the vehi-
cle. Speed and driving style should always
be adapted to traffic and road conditions.

The towing eyelet is located under the floor of
the cargo area. This eyelet must be screwed
into the positions provided on the right sides of
either the front or rear bumper (see the illustra-
tion).
To attach the towing eyelet:1. Press the mark on the lower edge of the
cover (1) to open it.
2. Screw the towing eyelet (3) in place first by
hand and then using the tire iron until it is
securely in place.
After the vehicle has been towed, the eye-
let should be removed and returned to its
storage space.

Press the cover back into position.
WARNING
Do not use the towing eyelets to pull the
vehicle up onto a flat bed tow truck.
Towing a vehicle with all four wheels on
the ground
WARNING
Volvo does not recommend towing a disa-
bled vehicle behind another vehicle. Signif-
icant difficulty in steering and braking, com-
bined with unfavorable weather, traffic, and
road conditions may make it impossible to
maintain vehicle control.
1. Apply the parking brake.
WARNING
Towing a vehicle with a locked steering
wheel will make the vehicle impossible to
steer.
2. Insert the key into the ignition to unlock the
steering wheel. The steering wheel must beunlocked. With the engine off and the vehi-
cle at a standstill, great effort will be
required to turn the steering wheel.
3.
Turn the ignition key to position II.
4. Place the gear selector in neutral. For vehi-
cles with automatic transmissions, follow
instruction on page 153, "Shiftlock over-
ride" to allow the gear selector to be moved
from the Park position.
5. Keep firm pressure on the brake pedal
while releasing the parking brake.
6. When towing has been completed, return
the gear selector to Park (automatic) or
Reverse (manual) and apply the parking
brake.
The following points should also be
observed:
•Never exceed 50 mph (80 km/h). Never
exceed local towing speed limits and heed
all local towing restrictions.
•Never tow farther than 50 miles (80 km).
•Keep the tow rope taut at all times while the
vehicle is in motion.
•The disabled vehicle should be towed in
the forward direction only.
