Automatic transmission (Geartronic)
Manual shifting - Geartronic
You can move the gear selector freely between
the (MAN)ual and (D)rive positions while
driving. Gears 2, 3, 4, and 5 have a "lock-up"
function which reduces engine speed and helps
save fuel.

Please refer to the information on page 95.
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 engaged.
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.

WARNING!
•Driving with the tailgate open: Driving
with the tailgate open could mean that
poisonous exhaust gases enter the
passenger compartment.
If the tailgate must be kept open for any
reason, proceed as follows:
- Close the windows.
- Set the ventilation system to air flow to
floor, windshield and side windows and
blower control to its highest setting.
•Floor mats: An extra mat on the driver's
floor can cause the accelerator pedal to
catch. Check that the movement of the
accelerator pedal is not impeded. Not
more than one protective floor covering
may be used at one time.
Cooling system
The risk for engine overheating is greatest,
especially in hot weather, when:

Emergency towing
The towing eyelet is located in the tool bag,
under the floor of the cargo area, with the
spare tire. This eyelet must be screwed into the
positions provided on the right sides of either
the front or rear bumper (see illustration). To
attach the towing eyelet:

CAUTION:
•Please check with state and local authori-
ties before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing device,
lighting, etc.
•If the car’s battery is dead, do not attempt
to start the vehicle by pushing or pulling it
as this will damage the three-way catalytic
converter(s). The engine must be jump
started using an auxiliary battery (see page
109).
•If the car is being towed on a flat bed
truck, the towing eyelets must not be used
to secure the car on the flat bed. Consult
the tow truck operator.
WARNING!
•Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but the
brake pedal pressure required is 3 - 4
times above normal and greater steering
effort must be exerted.
•The towing eyelets must not be used for
pulling another vehicle out of a ditch or
for any similar purpose involving severe
strain.
•Do not use the towing eyelets to pull the
car up onto a flat bed tow truck.

WARNING!
•Bumper-attached trailer hitches must not be used on Volvo’s, nor
should safety chains be attached to the bumper.
•Trailer hitches attaching to the vehicle rear axle must not be used.•Never connect a trailer’s hydraulic brake system directly to the
vehicle brake system, nor a trailer’s lighting system directly to the
vehicle lighting system. Consult your nearest authorized Volvo
retailer for correct installation.
•When towing a trailer, the trailer’s safety wire must be correctly
fastened to the hole or hook provided in the trailer hitch on the car.
The safety wire should never be fastened to or wound around the
drawbar ball.
NOTE:
•When parking the car with a trailer on a hill, apply the parking
brake before putting the gear selector in (P)ark or reverse on
models with a manual transmission. Always follow the trailer
manufacturer's recommendations for wheel chocking.
•When starting on a hill, put the gear selector in (D)rive before
releasing the parking brake.
•If you use the manual (Geartronic) shift positions while towing a
trailer, make sure the gear you select does not put too much strain
on the engine (using too high a gear).
•The drawbar assembly/trailer hitch may be certified for trailers that
are heavier than the car is designed to tow. Please adhere to Volvo’s
recommended trailer weights.
* When driving for prolonged periods at temperatures above 86° F
(30° C), the maximum recommended weight is 2000 lbs (900 kg).
When preparing for trailer towing, observe
the following:
Volvo recommends the use of Volvo trailer hitches which are specially
designed for the car.

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 towing. 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.

NOTE: When the car 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 normal and is caused by an built-in function in the
power brake system.
Power brakes function only when the engine
is running

Anti-lock Brake System (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 Volvo retailer for inspection.
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,
which 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.
To obtain optimal effect from the ABS system, constant pressure
should be kept on the brake pedal. Do not pump the brake pedal.
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.
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 during 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.
