Tire rotation
Summer and winter tires
When switching between summer and winter tires, mark the tires to indicate where they were mounted on the car,
e.g. LF = left front, RR = right rear
Tires with tread designed to roll in only one direction are marked with an arrow on the sidewall.
Incorrectly mounted tires impair the car's braking properties and ability to force aside rain, snow and slush.
The tires with the most tread should always be at the rear (to reduce the risk of skidding).
Contact a Volvo workshop if you are unsure about the tread depth.
Tire rotation
Your vehicle has no recommended tire rotation. The following information is intended to help you understand why.
Tread set
As a tire ages and the rubber cures, front and rear tires set at different angles. Therefore, if tires are rotated, the tread
will eventually set at an angle that is a compromise. Even if ride, handling, and road noise may still seem acceptable,
they may not be optimal. Further, tires that are rotated, but not on a regular basis, may actually cause more tire noise,
faster tire wear, and unpleasant changes in steering feel and vehicle handling.
A tire that can fully adapt to its position will provide better steering feel, lower tire noise, and better fuel economy.
Braking stability performance
Your vehicle is driven mainly by the front tires, which will wear faster. This can be beneficial. Having more tread on
the rear tires will help reduce oversteer. Oversteer is when a vehicle wants to keep turning because of momentum and
dynamic forces on its suspension.
Suspension wear diagnostics
Every suspension needs periodic inspection and maintenance. A tire's wear pattern can be an aid in detecting a
suspension problem. Each tire, if left in place, tells a story about the suspension. Tire rotation, on the other hand, could
make suspension wear harder to detect. Early detection is very important, because suspension problems can make tire
wear worse.
If you do rotate your tires...
Please follow the tire manufacturer's recommendations, as outlined in the tire manufacturers tire warranty pamphlet.

Tire sealing system
Introduction
Certain models are equipped with a tire sealing system that enables you to temporarily seal a hole in the tread surface
and reinflate a flat tire, or to adjust a tire's inflation pressure.
The system consists of an air compressor, a container for the sealing compound, wiring to connect the system to the
vehicle's electrical system via one of the 12-volt sockets, and a hose used to connect the system to the tire's inflation
valve.
The 12-volt sockets are located in the front tunnel console and in the trunk (option). See pages 66
and 108.
Accessing the tire sealing system
The tire sealing system is stowed in the compartment in the rear side of the ski hatch in the center of the rear seat
backrest. See page 109
for information on opening this hatch
NOTE
The tire sealing system is only intended to seal holes on the tire's tread area, not the sidewall.
Tires with large holes or tears cannot be repaired with the tire sealing system.
WARNING
After using the tire sealing system, the vehicle should not be driven farther than approximately 120 miles (200
km). Have the tire replaced as soon as possible.
The vehicle should not be driven faster than 50 mph (80 km/h) while using a tire that has been temporarily
repaired with the tire sealing system.
After using the tire sealing system, drive carefully and avoid abrupt steering maneuvers and sudden stops.

Tire sealing system
Overview
1. Speed limit sticker
2. On/Off switch
ProCarManuals.com

Temporarily repairing a flat tire is done in two stages:
Stage 1: The hole is sealed by pumping sealing compound into the tire. The car is then driven a short distance to
distribute the sealing compound in the tire.
NOTE
Do not remove any foreign objects (nails, etc.) from the tire before using the sealing system.
NOTE
Stage 2: The tire's inflation pressure is checked and adjusted if necessary.
WARNING
Never leave the tire sealing system unattended when it is operating.
Keep the tire sealing system away from children.
Be sure the vehicle is parked safely off the road and away from moving traffic.
Apply the parking brake.
Stage 1: Sealing the hole
1. Open the cover on the tire sealing kit.
2. Peel off the speed limit sticker and affix it to the steering wheel hub where it will be clearly visible to the driver.
3. Ensure that the on/off switch is in position 0 (the 0 side of the switch should be pressed down).
4. Put on the gloves included in the tire sealing system.
5. Unscrew the orange cover over the bottle holder and unscrew the cap on the bottle of sealing compound.
NOTE
Do not break the seal on the bottle. This occurs automatically when the bottle is screwed into the holder.
6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep it securely in place and help prevent sealing compound leakage. Once in
place, the bottle cannot be unscrewed. This must be done by a Volvo retailer.
7. Remove the valve cap from the tire's inflation valve and screw the tire sealing system's hose connector onto the
valve as tightly as possible by hand.
8. Connect the electrical wire to the nearest 12-volt socket in the vehicle.

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.
Fluid type : Volvo power steering fluid or equivalent.
Replace : No fluid change required.
WARNING
If a problem should occur in the power steering 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.

USB/iPOD connector (option)
ProCarManuals.com

An auxiliary device, such as an iPOD or a USB flash drive can be connected to the audio system via the connector in
the center console storage compartment.
A sound source must be chosen, depending on the device that has been connected:
1. Use MODE to select iPOD or USB. The text CONNECT DEVICE will be displayed.
2. Connect the device to the connector in the center console storage compartment (see the illustration).
The text LOADING will be displayed while the system indexes the files on the device. This may take a short time.
When indexing has been completed, track information will be displayed, and the desired track can then be selected.
Tracks can be selected in two ways:
Turn the Tuning knob (no. 4 in the illustration on page 234) clockwise or counterclockwise
Use the right or left arrow keys on the navigation control (no. 5 in the illustration on page 239) to select the desired
track. The arrow keys on the steering wheel keypad can also be used in the same way.
NOTE
The system supports playback of files in the most common versions of formats such as mp3, wma, and wav.
However, there may be versions of these formats that the system does not support.
USB flash drive
To simplify the use of a USB flash drive, it is advisable to only store music files on the drive. It will take considerably
longer for the system to index the files on the drive if it contains anything other than compatible music files.
MP3 player
Many mp3 players have a file indexing system that is not supported by the vehicle's audio system. In order to use an
mp3 player, the system must be set to USB Removable device/Mass Storage Device.
iPod
An iPod receives current and its battery is charged through the connecting cord. However, if the iPOD's battery is
completely drained, it should be recharged before the iPOD is connected to the audio system.
NOTE
When an iPOD is used as a sound source, the vehicle's audio system has a menu structure similar to the one in the
iPOD. See the iPOD's manual for detailed information.
