Shift gate positions
You can move the gear selector freely between the (MAN)ual and (D)rive positions while driving.
Depress the button on the front of the gear selector knob to move betwee\
n the R, N, D, and P positions.
Manual shifting
You can move the gear selector freely between the (MAN)ual and (D)rive positions while driving. Gears
3, 4, 5, and 6 (where applicable) have a "lock-up" function which redu\
ces engine speed and helps save
fuel.
The currently selected gear will be displayed in the instrument panel (\
see
page 46).
pg. 133 Starting and driving
Geartronic (option)
l To access the (MAN)ual shifting position from (D)rive, move the gear selector to the left to MAN.
l To return to the (D)rive position from MAN, move the gear selector to the right.
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.
l Move the gear selector forward (toward "+") to shift to a higher gear \
or rearward (toward "-") to shift
to a lower gear.
l If you hold the gear selector toward "-", the transmission will downshif\
t 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 t\
o be used.
l If you slow down to a very low speed, the transmission will automaticall\
y shift down.
l When starting in the (MAN)ual position, 3rd gear is the highest gear that may be selected.
NOTE: Kickdown does not function when the transmission is in the manual shift\
(Geartronic) mode.

The gear selector must be in the D (Drive) position.
Kickdown
Automatic shift to a lower gear (kickdown) is achieved by depressing t\
he accelerator pedal fully and
briskly. An upshift will occur when approaching the top speed for a part\
icular gear or by releasing the
accelerator pedal slightly.
Kickdown can be used for maximum acceleration or when passing at highway\
speeds.
Kickdown does not function when the transmission is in the manual shift \
(Geartronic) mode.
W - Winter/Wet driving mode - enhanced vehicle traction
Please refer to the information on
page 131.
Sport mode (R-models only)
R-models are equipped with a (S)port button that can be used to engage\
/disengage the Sport shifting
mode. An indicator light in the button will go on when Sport mode is eng\
aged.
With Sport mode engaged, the transmission will shift up at higher rpm in\
first and second gears, and will
also shift down at higher rpm for more immediate engine response during \
acceleration and deceleration.
pg. 134 Starting and driving
All Wheel Drive (option)
All Wheel Drive (AWD) - general information
Your Volvo can be equipped with permanent All Wheel Drive, which means t\
hat power is distributed
automatically between the front and rear wheels. Under normal driving co\
nditions, most engine's power
is directed to the front wheels. However, if there is any tendency for t\
he front wheels to spin, an
electronically controlled coupling distributes power to the wheels that \
have the best traction.

This mode is recommended for long-distance driving, or when driving in s\
lippery conditions. The
indicator light in the button will be off when this mode is selected.
If Comfort mode was selected when the engine was switched off, this mode\
will still be active when the
engine is restarted.
Sport
In this mode, shock absorption is stiffer to reduce the vehicle's body s\
way during cornering and to
provide more immediate steering response. The indicator light in the but\
ton will come on to indicate that
Sport mode has been selected.
If this setting was selected when the engine was switched off, Sport mod\
e will still be active when the
engine is restarted.
Advanced sport (V70 R only)
In this mode, movement of the shock absorbers is minimal, response from \
pressure on the throttle pedal
is more direct, and body sway in curves or when cornering is sharply red\
uced.
If Advanced sport mode was selected when the engine was switched off, Sport mode will be active
when the engine is restarted.

Brake system
BRAKE Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinder\
s and two separate brake
circuits. If a problem should occur in one of these circuits, it is stil\
l possible to stop the vehicle with the
other brake circuit.
If the brake pedal must be depressed farther than normal and requires gr\
eater 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 ch\
eck 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\
failure - Service urgent"
message is displayed in the text window: DO NOT DRIVE. Have the vehicle \
towed to a Volvo
retailer and have the brake system inspected.
NOTE: When the vehicle is at a standstill and the engine is idling, e.g. at a\
traffic light and the brake
pedal is depressed, the pedal may go down slightly. This is a normal fun\
ction of the power-assisted
brake system.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the \
engine is running. Never let
the vehicle roll to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed app\
roximately four times harder
than usual to make up for the lack of power assistance. This can happen \
for example when towing your
vehicle or if the engine is switched off when the vehicle is rolling. Th\
e 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 c\
ause 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 occasionally \
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 weath\
er.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or\
hilly areas or towing. Vehicle
speed is usually slower, which means that the cooling of the brakes is l\
ess 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 wil\
l be subjected to a greater than
normal load.

Anti-lock brakes (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (\
the standard braking system will
however function) and the vehicle should be driven cautiously to a Volv\
o retailer for inspection. The
Anti-lock Braking System (ABS) helps to improve vehicle control (stop\
ping and steering) during severe
braking conditions by limiting brake lockup. When the system "senses" im\
pending lockup, braking
pressure is automatically modulated in order to help prevent lockup, whi\
ch could lead to a skid.
The system performs a self-diagnostic test when the engine is started an\
d when the vehicle first
reaches a speed of approximately 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.
To obtain optimal effect from the ABS system, constant pressure should b\
e kept on the brake pedal. Do
not pump the brake pedal.
The switching of the ABS modulator will be audible and the brake pedal w\
ill pulsate during braking.
Please be aware that ABS does not increase the absolute braking potentia\
l of the vehicle. While control
will be enhanced, ABS will not shorten stopping distances on slippery su\
rfaces.
ABS with EBD (Electronic Brake Force Distribution)
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 brake pedal will pulsate duri\
ng braking, which is normal.
If the BRAKE and ABS warning lights come on at the same time, this could\
indicate a fault in the brake
system.
- Stop the vehicle in a suitable place and switch off the engine.
- Restart the engine.
- If both warning lights go off, no further action is required.
- If both lights are still on after the engine has been restarted, switc\
h off the engine again and check the
brake fluid level (see
page 193 for the location of the brake fluid reservoir).
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake\
failure - Service urgent"
message is displayed in the text window: DO NOT DRIVE. Have the vehicle \
towed to a Volvo
retailer and have the brake system inspected.
- If the brake fluid level is above the MIN mark, drive carefully to an \
authorized Volvo retailer and have
the brake system inspected.
Emergency Brake Assistance (EBA)
The EBA function is designed to provide full brake effect immediately in\
the event of sudden, hard
braking. The system is activated by the speed with which you depress the\
brake pedal.

NOTE:
l When the EBA system is activated, the brake pedal will go down and press\
ure in the brake system
immediately increases to the maximum level. You must maintain full press\
ure on the brake pedal in
order to utilize the system completely. There will be no braking effect \
if the pedal is

Brake system
released. EBA is automatically deactivated when the brake pedal is relea\
sed.
l 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.

Stability system
Stability Traction Control (STC)/ Dynamic Stability Traction Control (\
DSTC)
The stability system consists of a number of functions designed help red\
uce wheel spin, counteract
skidding, and to generally help improve directional stability.
NOTE: A pulsating sound will be audible when the system is actively operating\
and is normal.
1. Standard on all models except the T5 turbo and R-models. Models equip\
ped with All Wheel Drive (AWD)
have an integrated traction control function, and are not equipped with \
an STC button. DSTC is optional on
AWD models.
2. Standard on the T5 turbo and R-models, option on all other models.
Traction control (TC)
This function is designed to help reduce wheel spin by transferring powe\
r from a drive wheel that begins
to lose traction to the wheel on the opposite side of the vehicle (on t\
he same axle).
TC is most active at low speeds.
This is one of the STC/DSTC's permanent functions and cannot be switched\
off.

Spin control (SC)
The spin control function is designed to help prevent the drive wheels f\
rom spinning while the vehicle is
accelerating.
Under certain circumstances, such as when driving with snow chains, or d\
riving in deep snow or loose
sand, it may be advisable to temporarily switch off this function for ma\
ximum tractive force.
Temporarily switching off Spin control

l The message STC/DSTC SPIN CONTROL OFF indicates that the stability syste\
m's spin control
function has temporarily been switched off.
l The stability control indicator light will illuminate and remain on until spin control has been
reactivated.
l STC/DSTC ON indicates that all system functions are active1.
l The spin control function is automatically enabled each time the engine \
is started.
