2006 VOLVO C70 key battery

Steering wheel lock
When the key is removed from the ignition, the steering wheel locks so that it cannot be turned.
If the front wheels are hard up against a curb, the steering wheel lock may be under too much tension to unlock. If so,
the key will turn in the ignition switch but the car will not start. At the same time, a message "Steering locked" will
appear in the driver information text display.
If this happens:
Remove the key from the ignition.
Turn the steering wheel slightly and hold it to relieve pressure on the lock mechanism. Reinsert it the key. The
steering should immediately unlock. If not, try again.
NOTE: In order to help reduce vehicle theft, make sure the steering wheel lock is engaged before leaving the vehicle.
WARNING!
Never switch off the ignition (turn the ignition key to position 0) or remove the key from the ignition switch while
the vehicle is in motion. This could cause the steering wheel to lock, which would make the vehicle impossible to
steer.
1. The gear selector must be in the Park position.
2. Please be aware that leaving the key in this position will increase battery drain.
pg. 105 Starting and driving
Starting the engine
To start the engine:
Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Adjust the seat if necessary.
Apply the parking brake, if not already set. The gear selector (automatic transmission) is locked in the (P)ark position
(SHIFTLOCK). See also page 108
.
Manual transmission: The clutch must be fully depressed.
Without touching the accelerator pedal, turn the ignition key to the starting position. Allow the starter to operate for
up to 10 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat this step.
Autostart (T5 turbo with automatic transmission only)
This function makes it possible to start the vehicle without holding the key in position III. Turn the key to position III
and release it. The starter motor will then operate automatically (for up to ten seconds) until the engine starts.
NOTE: After a cold start, idle speed may be noticeably higher than normal for a short period. This is done to help
bring components in the emission control system to their normal operating temperature as quickly as possible, which
enables them to control emissions and help reduce the vehicle's impact on the environment.
For cold starts at altitudes above 6000 ft. (1800 meters), depress the accelerator pedal halfway and turn the key to
the starting position. Release the pedal slowly when the engine starts.
To release the gear selector from the (P)ark position, the engine must be running (or the ignition key must be in

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, for example if the
battery is discharged.
Manually overriding the Shiftlock system:
Apply the parking brake.
Depress the brake pedal.
There is a small cover behind P-R-N-D on the gear selector panel. Open the rear edge of the panel.
Insert the key blade (see page 88
) or a screwdriver into the opening and press it down until it bottoms and move the
gear selector out of the P position.

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
ProCarManuals.com

Screw the towing eyelet in place first by hand and then using the tire iron until it is securely in place (3).
After the vehicle has been towed, the eyelet should be unscrewed and returned to its storage place. Press the plastic
cover in bumper back into position.
WARNING!
Volvo does not recommend towing a disabled vehicle behind another vehicle. Significant difficulty in steering and
braking, combined with unfavorable weather, traffic, and road conditions may make it impossible to maintain
vehicle control.
Towing a vehicle with all four wheels on the ground
Apply the parking brake.
Insert the key into the ignition to unlock the steering wheel. The steering wheel must be unlocked. With the engine
off and the vehicle at a standstill, great effort will be required to turn the steering wheel.
WARNING!
Towing a vehicle with a locked steering wheel will make the vehicle impossible to steer.
Turn the ignition key to position II.
Place the gear selector in neutral. For vehicles with automatic transmissions, follow instruction on page 110,
"Shiftlock override" to allow the gear selector to be moved from the Park position.
Keep firm pressure on the brake pedal while releasing the parking brake.
When towing has been completed, return the gear selector to Park (automatic) or Reverse (manual) and apply the
parking brake.
pg. 118 Starting and driving
Towing
The following points should also be observed:
Never exceed 50 mph (80 km/h). Never exceed local towing speed limits and heed all local towing restrictions.
Never tow farther than 50 miles (80 km).
Keep the tow rope taut at all times while the vehicle is in motion.
The disabled vehicle should be towed in the forward direction only.
WARNING!
Never allow a vehicle to be towed without a driver behind the wheel of the disabled vehicle.
Never remove the key from the ignition while the vehicle is moving. The steering wheel could lock, making it
impossible to steer the vehicle.
When the engine is not running, steering resistance and the effort needed to apply the brakes will be great.
Never attempt to tow a vehicle with a dead battery at night.
CAUTION!
Check with state and local authorities 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, marker flags, etc.

Battery
Battery maintenance
Driving habits and conditions, climate, the number of starts, etc., all affect the service life and function of the battery.
In order for your battery to perform satisfactorily, keep the following in mind:
Check the fluid level in each cell in the battery every 24 months or every 15,0001 miles (24,000 km), whichever is
sooner. The fluid should be at the level shown in the illustration above (A). Do not overfill.
Use a screw driver to open the caps and a flashlight to inspect the level.
If necessary, add distilled water. The level should never be above the indicator (A).
The fluid level should be checked if the battery has been recharged.
After inspection, be sure the cap over each battery cell is securely in place.
Check that the battery cables are correctly connected and properly tightened.
Never disconnect the battery when the engine is running, or when the key is in the ignition. This could damage the
vehicle's electrical system.
