2008 VOLVO C70 ignition

TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire
pressure, please refer to the tables beginning on page 172 or consult your Volvo retailer.
The tire pressure warning light will not identify which tire is underinflated. Be sure to check all four tires.
A certain amount of air seepage from the tires occurs naturally and tire pressure fluctuates with seasonal changes
in temperature. Always check tire pressure regularly.
Erasing warning messages
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
1. Use a tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the tables beginning on page 172
.
3. In certain cases, it may be necessary to drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or
faster. This will erase the warning text and the warning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of the vehicle.
Changing wheels with TPMS
Please note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary spare tire, this tire does not have a TPMS sensor.
If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SYST SERVICE REQUIRED will be
displayed each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed, the warning message should not reappear. If the message is still
displayed, drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster to erase the message.
Volvo recommends that TPMS sensors be fitted on all wheels used on the vehicle. Volvo does not recommend
moving sensors back and forth between sets of wheels.
NOTE
If you change to tires with a different recommended inflation pressure, the TPMS system must be recalibrated to
these tires. This must be done by a trained and qualified Volvo service technician.
If a tire is changed, or if the TPMS sensor is moved to another wheel, the sensor's seal, nut, and valve core should
be replaced.
When installing TPMS sensors, the vehicle must be parked for at least 15 minutes with the ignition off. if the
vehicle is driven within 15 minutes, a TPMS error message will be displayed.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or
otherwise damaging the valve.

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 illustrations above (A). Do not overfill.
1More frequently in warm climates.
Use a screw driver to open the caps or cover 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 or the cover 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.
The battery should be disconnected from the vehicle when a battery charger is used directly on the battery.

Three-way catalytic converter
General information
Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical, fuel or distributor
ignition systems, may cause unusually high three-way catalytic converter temperatures. Do not continue to operate your
vehicle if you detect engine misfire, noticeable loss of power or other unusual operating conditions, such as engine
overheating or backfiring. A properly tuned engine will help avoid malfunctions that could damage the three-way
catalytic converter.
Do not park your vehicle over combustible materials, such as grass or leaves, which can come into contact with the hot
exhaust system and cause such materials to ignite under certain wind and weather conditions.
Excessive starter cranking (in excess of one minute), or an intermittently firing or flooded engine can cause three-way
catalytic converter or exhaust system overheating.
Remember that tampering or unauthorized modifications to the engine, the Electronic Control Module, or the vehicle
may be illegal and can cause three-way catalytic converter or exhaust system overheating.
This includes:
- Altering fuel injection settings or components.
- Altering emission system components or location or removing components.
- Repeated use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
