Introduction
The HomeLink 1
Wireless Control System pro-
vides a convenient way to replace up to three hand-held radio-frequency (RF) transmittersused to activate devices such as gate opera-tors, garage door openers, entry door locks,security systems, even home lighting. Addi-tional HomeLink information can be found onthe Internet at www.homelink.com or byphoning the hotline at 1–800–355–3515.
WARNING
• If you use HomeLink to open a garage door or gate, be sure no one is nearthe gate or door while it is in motion.
• When programming a garage dooropener, it is advised to park outside ofthe garage.
• Do not use HomeLink with any garagedoor opener that lacks safety stop andreverse features as required by U.S.federal safety standards (this includesany garage door opener model manu-factured before April 1, 1982). Agarage door that cannot detect anobject - signaling the door to stop andreverse - does not meet current U.S.federal safety standards. For moreinformation, contact HomeLink at:www.homelink.com.
Retain the original transmitter of the RF device you are programming for use in othervehicles as well as for future HomeLink pro-gramming. It is also suggested that upon thesale of the vehicle, the programmed Home-Link buttons be erased for security purposes.Refer to “Resetting HomeLink Buttons” onpage 115.
Programming HomeLink
NOTE
Some vehicles may require the ignition to be switched on or be in the “accessories”position for programming and/or operationof HomeLink. It is also recommended thata new battery be placed in the hand-heldtransmitter of the device being pro-grammed to HomeLink for quicker trainingand accurate transmission of the radio-fre-quency signal. The HomeLink buttonsmust be reset first. When this has beencompleted, Homelink is in learning modeso that you can perform programming.
1. Position the end of your hand-held trans-
mitter 1–3 inches (5–14 cm) away from the HomeLink button you wish to pro-gram while keeping the indicator light inview.

Gear indicatorThe gear currently being used is displayed on the rightside of the instrument panel. The " S" symbol turns orange
if Sport mode is being used.
Reverse: position RThe vehicle must be stationary when position R is selected.
Neutral: position NNo gear is engaged and the engine can bestarted with the gear selector in this position.Apply the parking brake if the vehicle is sta-tionary with the gear selector in position N.
Drive: position DD is the normal driving position. The car auto-
matically shifts between the various forwardgears, based on the level of acceleration andspeed. The car must be at a standstill whenshifting from position R to position D.
Geartronic: manual shifting (+S–)Geartronic allows you to manually shiftamong your vehicle's forward gears. Gear-tronic can be selected at any time. To shift gears manually, move thegear selector to the side from
D
toward +S–. The +S– symbol in the
instrument panel will change from
white to orange and the number of the gear
currently being used (
1, 2, 3, etc.) will be dis-
played (see the following illustration).
• To return to automatic shifting mode from +S–
, move the gear selector to the side
toward D.
Gear shift indicator*

This option indicates when to shift up or down to help conserve fuel. A white arrow willappear above or below the number of thecurrent gear to prompt the driver to shift upor down.
While driving
• If you select the manual shifting position while driving, the gear that was beingused in the Drive position will also initiallybe selected in the manual shifting posi-tion.
• Move the gear selector forward (toward
+)
to shift to a higher gear or rearward(toward –) to shift to a lower gear.
• If you hold the gear selector toward "–",the transmission will downshift one gearat a time and will utilize the braking powerof the engine. If the current speed is toohigh for using a lower gear, the downshiftwill not occur until the speed hasdecreased enough to allow the lower gearto be used.
• If you slow to a very low speed, the trans-mission will automatically shift down.
Shiftlock: Neutral (N)If the gear selector is in the
N position and
the vehicle has been stationary for at least 3 seconds (irrespective of whether the engineis running) then the gear selector is locked. In order to move the gear selector from N to
another gear position, the brake pedal must be depressed and the ignition must be in atleast position II, see page 84.

•
The gear selected is moved to
P,N or R
• The driver presses the
button to put
ACC in standby mode
The parking brake is applied
automatically
In certain situations, ACC will apply the park- ing brake in order to continue keeping thevehicle at a standstill. This happens if:
• The driver opens the door or takes off his/her seat belt
• DSTC is put in Sport mode (seepage 144)
• ACC has kept the vehicle at a standstillfor more than 2 minutes
• The engine has been switched off
• The brakes have overheated
The radar sensor and its limitations
In addition to being used by ACC, the radar sensor is also used by Distance Alert (seepage 161) and Collision Warning with FullAuto-brake and Pedestrian Detection (seepage 170). This sensor is designed to detectcars or larger vehicles driving in the samedirection as your vehicle, in the same lane.
WARNING
• If there is visible damage to the front grille or you suspect that the radarsensor may be damaged in any way,contact a trained and qualified Volvoservice technician as soon as possible.The radar sensor may only functionpartially (or not at all) if it is damagedor is not securely fastened in place.
• Accessories or other objects, such asextra headlights, must not be installedin front of the grille.
• Modification of the radar sensor couldmake its use illegal.
The radar sensor's capacity to detect vehi- cles ahead is impeded:
• if the radar sensor is obstructed and can- not detect other vehicles, for example inheavy rain, or if snow or other objects areobscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
• if the speed of vehicles ahead is signifi- cantly different from your own speed.
Situations where ACC may not function optimally
WARNING
•The radar sensor has a limited field of vision. In some situations it may detecta vehicle later than expected or notdetect other vehicles at all.
• If ACC is not functioning properly,cruise control will also be disabled.

07 During your trip
Loading
07
284* Option/accessory, for more information, see Introduction.
Introduction
The load carrying capacity of your vehicle is determined by factors such as the number ofpassengers, the amount of cargo, the weightof any accessories that may be installed, etc. To increase loading space, the rear seat backrests can be folded down, see page 89. When loading the trunk, keep the following in mind:
The trunk lid can be unlocked anpopped open slightly via the buttonlocated on the lighting panel, see
page 68.
• Load objects in the trunk against the backrest whenever possible.
• Unstable loads can be secured to theload anchoring eyelets with straps or weblashings to help keep them from shifting.
• Stop the engine and apply the parkingbrake when loading or unloading longobjects. The gear selector can beknocked out of position by long loads,which could set the vehicle in motion.
WARNING
• Stop the engine, put the gear selector in
P, and apply the parking brake
when loading or unloading longobjects.
• The vehicle's driving characteristicsmay change depending on the weightand distribution of the load.
• A 44-pound (20 kg) object produces aforce of 2,200 pounds (1,000 kg) in ahead-on collision at 30 mph (50 km/h).
• The rear seat should not be loaded toa level higher than 2 in. (5 cm) belowthe upper edge of the rear side win-dows. Objects placed higher than thislevel could impede the function of theVolvo Inflatable Curtain.
Folding down the rear seat backrests
The rear seat backrests can be folded down for additional loading space, see page 90.
Load anchoring eyelets
G021462
The load anchoring eyelets on both sides of the vehicle are used to fasten straps, etc., tohelp anchor items in the trunk.
