Volvo service technician.
NOTE
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has a
lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
207 09 Maintenance and servicing
Fluids
CAUTION
The cooling system must always be kept filled to the correct level, and the level must be between the MIN and
MAX marks. If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Different types of antifreeze/coolant may not be mixed. Check coolant regularly!
WARNING
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools. If it is necessary to top off the
coolant when the engine is warm, unscrew the expansion tank cap slowly so that the overpressure dissipates.
Brake fluid
The brake fluid should always be between the MIN and MAX marks on the side of the reservoir. Check, without
removing the cap, that there is sufficient fluid in the reservoir.
Fluid type: DOT 4+ boiling point >536°F (280°C), P/N 9437433
Replace: The fluid should be replaced according to the intervals specified in the Warranty and Service Records
Information booklet. When driving under extremely hard conditions (mountain driving, etc), it may be necessary to
replace the fluid more often. Consult your Volvo retailer. Always entrust brake fluid changing to a trained and
qualified Volvo service technician.
Power steering fluid
The fluid level is checked at each service interval.

retailer.
WARNING

Do not smoke near the battery.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
211 09 Maintenance and servicing
Replacing bulbs
Introduction
Before replacing bulbs in your vehicle, please keep the following points in mind:
NOTE
Never touch the glass of bulbs with your fingers. Grease and oils from your fingers vaporize in the heat and will
leave a deposit on the reflector, which will damage it.
The optional Bi -Xenon® headlight bulbs contain trace amounts of mercury. These bulbs should always be
disposed of by an authorized Volvo retailer.
Certain bulbs should only be replaced by a trained and qualified Volvo service technician:
- Courtesy (dome) lighting
- Reading lights
- Glove compartment lights
- Turn signals and courtesy lights in the side door mirrors
- High-mounted brake lights
- Bi -Xenon® headlights
- Brake lights
