Starting the engine
Jump starting
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 touching to
prevent premature completion of a circuit. Be sure to follow jump starting instructions 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 auxiliary 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
(+) terminal jumper cable (red).
WARNING
PROPOSITION 65 WARNING!
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the state of
California to cause cancer and reproductive harm. Wash hands after handling.
CAUTION
Connect the jumper cables carefully to avoid short circuits with other components in the engine compartment.
WARNING

The vehicle must be stationary when position 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 stationary with the gear selector in position N .
Drive (D)
D is the normal driving position. 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 from position R to position D.

Transmission
Geartronic-manual shifting
Geartronic allows you to manually shift among your vehicle's six forward speeds. Geartronic can be selected at any
time.
To access the manual ( M) shifting position from Drive ( D), move the gear selector to the right to M .
To return to the 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 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.
Shiftlock - Neutral ( N)
If the gear selector is in the N position and the vehicle has been stationary for at least 3 seconds (irrespective of
whether the engine is running) 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 position II , see page 80
.

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 so that the vehicle can be moved
1.
Lift away the rubber mat on the floor of the storage compartment behind the center console and open the hatch.
Insert the key blade into the opening as far as possible. Press the key blade down and keep it held down. Move the
gear selector from the P position. For information on the key blade, see page 52
.
1If the battery is dead, the optional electric parking brake cannot be applied or released. Connect an auxiliary battery if the battery voltage is too
low, see page 109
.

Transmission
All Wheel Drive - AWD1
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 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.
1Standard on certain models.
113 03 Your driving environment
Brakes
Brake system
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
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 braking system
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 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.
114 03 Your driving environment
Brakes
Cleaning the brake discs
Coatings 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 braking gently for a short period while the vehicle is moving.
Emergency Brake Assistance

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.
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
increases to the maximum level. You must maintain full pressure on the brake pedal in order to utilize the system
completely. There will be no braking effect if the pedal is released. EBA is automatically 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.
