WARNING
•
Never remove the coolant reservoir
cap while the engine is warm. Wait
until the engine cools.
•
If it is necessary to top up the coolant
when the engine is warm, unscrew the
coolant reservoir cap slowly so that
the overpressure dissipates.
Brake fluid reservoir
The brake fluid should always be above the
MIN mark on the side of the reservoir. Check,
without removing the cap, that there is suffi-
cient fluid in the reservoir.
Fluid type: DOT 4 boiling point >536 °F
(>280 °C).
Replace: Every second year or 30,000 miles
(48,000 km). The fluid should be replaced
once a year or every 15,000 miles (24,000 km)
when driving under extremely hard conditions
(mountain driving, etc.).
Always entrust brake fluid changing to a
trained and qualified Volvo service technician.
WARNING
•
If the fluid level is below the MIN mark
in the reservoir or if a brake-related
message is shown in the information
display: DO NOT DRIVE. Have the car
towed to a trained and qualified Volvo
service technician and have the brake
system inspected.
•
Dot 4 should never be mixed with any
other type of brake fluid.
09 Maintenance and servicing
Power steering fluid reservoir
The fluid level should always be between the
ADD and FULL marks.
Fluid type: Volvo synthetic power steering
fluid (Pentosin CHF 11S) P/N 1161529 or
equivalent.
Replace: No fluid change required.
If a problem should occur in the power steer-
ing system or if the vehicle has no electrical
current and must be towed, it is still possible
to steer the vehicle. However, keep in mind
that greater effort will be required to turn the
steering wheel.
