N - Neutral
N is the neutral position. The engine can be started, but no gear is selected. Apply the
142 06 Starting and driving
Automatic transmission
parking 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 position.
D - Drive
D is the normal driving position. The Drive position offers 5 forward gears
1. The car automatically shifts between the
various 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 .
1T5 models have 6 forward gears.
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 ( M)anual shifting position from Drive ( D), move the gear selector to the right to M.
To return to the ( D)rive 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 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 transmission will automatically shift down.
ProCarManuals.com

Cold starts (turbo engines)
When driving before the engine has reached its normal operating temperature, the transmission will shift up at slightly
higher engine speeds to heat the three-way catalytic converter as quickly as possible.
143 06 Starting and driving
Automatic transmission
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.
Safety function
To 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.

Text messages and actions
In certain situations, the message may appear in the display and the information or warning symbol may illuminate.
The table shows two levels of severity if the transmission should overheat. In addition to the message in the display,
the driver will also be aware that the vehicle's electrical system has temporarily changed the driving characteristics.
Follow the instructions in the display.
See also page 57
for additional messages pertaining to the automatic transmission.
The message will disappear after the displayed action has been taken or if the READ button on the turn signal lever
has been pressed.
NOTE

Shiftlock override
Overriding the shiftlock system
Shiftlock prevents the gear selector from being moved out of Park unless the ignition key is in position II and the
brake pedal is depressed.
In certain cases it may be necessary to move the gear selector from the Park position manually.
To manually override the Shiftlock system:
1. Apply the parking brake.
2. Depress the brake pedal.
3. There is a small cover below P-R-N-D on the gear selector panel. Open the rear edge of the panel.
4. Insert the key blade (see page 115
) into the opening and press it down until it bottoms.
5. With the key blade pressed down, move the gear selector out of the P position.
146 06 Starting and driving
All Wheel Drive (option)
All Wheel Drive (AWD) - general information
Your Volvo can be equipped with permanent All Wheel Drive (option), which means that power is distributed
automatically between the front and rear wheels. Under normal driving conditions, most of the engine's power is
directed to the front wheels. However, if there is any tendency for the front wheels to spin, an electronically 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-,
ProCarManuals.com

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 the tire inflation pressure tables beginning on page 172
.
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 m.p.h. (80 km/h).
Never install snow chains on a temporary spare.
147 06 Starting and driving
Brake system
Brake circuit malfunction
The brake system is a hydraulic system consisting of two separate brake circuits. If a problem 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 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 approximately five 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. 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
ProCarManuals.com

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 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 automatically
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 approximately 12 m.p.h. (20 km/h). The brake pedal will pulsate several times and a sound may be audible from
the ABS control module. This is normal.
148 06 Starting and driving
Brake system
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 malfunction of the ABS system (the standard braking system will still function)
and the vehicle should be driven cautiously to a trained and qualified Volvo service technician for inspection.
WARNING
If the BRAKE and ABS warning symbols light at the same time, there may be a problem in the brake system. If the
brake fluid level is normal in these circumstances, drive carefully to the nearest trained and qualified Volvo service
technician to have the brake system checked.
Emergency Brake Assistance - EBA
EBA is designed to provide full brake effect immediately in the event of sudden, hard braking. 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.
