2008 VOLVO C70 transmission

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 .
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 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.
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.
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.

Towing a trailer
General information
Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle.
Maximum trailer weights recommended by Volvo are:
Trailers without brakes : 1,540 lbs (700 kg).
Trailers with brakes: 2,000 lbs (900 kg) Observe the legal requirements of the state/province in which the vehicles
are registered.
The maximum recommended hitch tongue load is 165 lbs ( 75 kg).
All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailer hitch installation should not
interfere with the proper operation of this bumper system.
Trailer towing does not normally present any particular problems, but take into consideration:
Increase tire pressure to recommended full. See the chapter "Wheels and tires."
When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km).
Maximum speed when towing a trailer: 50 m.p.h. (80 km/h).
Engine and transmission are subject to increased loads. Therefore, engine coolant temperature should be closely
watched when driving in hot climates or hilly terrain. Use a lower gear and turn off the air conditioner if the
temperature gauge needle enters the red range.
If the automatic transmission begins to overheat, a message will be displayed in the information display.
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability, and economy.
It is necessary to balance trailer brakes with the towing vehicle brakes to provide a safe stop (check and observe
state/local regulations).
Do not connect the trailer's brake system directly to the vehicle's brake system.
More frequent vehicle maintenance is required.
Remove the ball and drawbar assembly when the hitch is not being used.
Volvo recommends the use of synthetic engine oil when towing a trailer over long distances or in mountainous
areas.
WARNING
Bumper-attached trailer hitches must not be used on Volvos, nor should safety chains be attached to the bumper.
Trailer hitches attaching to the vehicle's 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 trained and qualified Volvo service technician for correct
installation.
When towing a trailer, the trailer's safety wire must be correctly fastened to the hole or hook provided in the
ProCarManuals.com

trailer hitch on the vehicle. The safety wire should never be fastened to or wound around the drawbar ball.
156 06 Starting and driving
Towing a trailer
NOTE
When parking the vehicle with a trailer on a hill, apply the parking brake before putting the gear selector in Park
( P ) or in reverse on models with a manual transmission. Always follow the trailer manufacturer's recommendations
for wheel chocking.
If you use the manual (Geartronic) shift positions while towing a trailer, or if the vehicle is equipped with a
manual transmission, 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 rated for trailers heavier than the vehicle is designed to tow. Please
adhere to Volvo's recommended trailer weights.
Avoid driving with a trailer on inclines exceeding 15%.

Temporary spare
Temporary spare (option)
The spare tire in your car is called a "Temporary Spare".
Recommended tire pressure (see the placard on the B-pillar) should be maintained irrespective of which position on
the car the temporary spare tire is used on.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.
Location of the optional spare wheel and tools
The spare wheel is packed in a storage bag and is located under the panel in the floor of the trunk.
On cars with a spare wheel, the jack and lug wrench are secured in a foam plastic block placed in the center of the
wheel.
CAUTION
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.
The retaining straps securing the spare wheel is attached to two eyelets in the floor of the spare wheel's storage
compartment.
WARNING
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. It must be replaced as soon as possible by a standard tire. Road holding and handling may be affected
with the "Temporary Spare" in use.
