Location of the backup reader in the tunnel console.
NOTE
When the remote key is placed in the backup reader, make sure that no othervehicle keys, metal objects or electronicdevices (e.g. cellular phones, tablets, lap-tops or chargers) are in the backup reader.Multiple vehicle keys close to each other inthe backup reader can disrupt their func-tionality.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before star-ting a new attempt. Starting capabilityincreases if the starter battery is given timeto recover.
WARNING
Never remove the remote control key from
the vehicle while driving or the vehicle is being towed.
WARNING
Always remove the remote key from the passenger compartment when youleave the vehicle and make sure theignition is in mode
0.
Always put the gear selector in
P and
apply the parking brake before leavingthe vehicle. Never leave the vehicleunsupervised while the engine is run-ning.
Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by thevehicle contain carbon monoxide,which is invisible and odorless but verytoxic.
CAUTION
When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it hasreached the proper operating tempera-ture.
The engine should be idling when thegear selector is moved. Never acceler-ate until the gear is fully engaged.Accelerating rapidly before a gear isproperly engaged could lead to harderwear of components.
To help prevent the transmission oilfrom overheating, select
P or N when
idling at a standstill for prolonged peri-ods of time.

Gear selector positions for automatic transmissions
With an automatic transmission, a suitable gear is selected automatically according tocurrent speed and power requirements.
Selecting gearsThe gear selector is a shift-by-wire selector, where shifting is done electronically instead ofmechanically. This makes shifting easier andthe gear positions more distinct.

The kickdown function Kickdown can be used when maximum acceleration is needed, e.g. when passing.
When the accelerator pedal is depressed all the way to the floor (past the normal full accel-erator position), the transmission will auto-matically engage kickdown, i.e. immediatelyshift down to a lower gear. If the accelerator pedal is released from the kickdown position, the transmission will auto-matically shift up again.
Safety function
The transmission control module is equipped with a downshift protection feature to helpprevent the engine from overheating. In some conditions, the transmission will pre- vent downshifting/kickdown if this would leadto such high engine speed (rpm) that theengine could be damaged. If the driver stillattempts downshifting or kickdown at a highrpm, nothing will happen and the original gearwill remain selected. With kickdown, the vehicle can downshift one or more steps at a time depending on theengine speed. The vehicle upshifts when theengine reaches its maximum rpm to preventengine damage.

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle if youdetect engine misfire, noticeable loss ofpower or other unusual operating condi-tions, such as engine overheating or back-firing. A properly tuned engine will helpavoid malfunctions that could damage thethree-way catalytic converter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, whichcan come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cata-lytic converter or exhaust system over-heating.
Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.

5268. Start the compressor by moving the
switch to the I (On) position.
WARNING
Never stand next to a tire being inflated with the compressor. If cracks, bulges, etc.form on the tire, switch off the compressorimmediately. The vehicle should not bedriven. Call roadside assistance to have thevehicle towed to a workshop for inspec-tion/replacement of the tire. Volvo recom-mends an authorized workshop.
NOTE
When the compressor first starts, air pres- sure may temporarily increase up to 6 bar(88 psi) but should decrease again afterapproximately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor should never be used for more than10 minutes at a time.
10. Switch off the compressor and check the
inflation pressure using the air pressure gauge. The inflation pressure should bebetween 1.8 bar (22 psi) and 3.5 bar(51 psi). If the inflation pressure is toohigh, use the air release valve to releaseair.
WARNING
If pressure falls below 1.8 bar (22 psi), the hole in the tire may be too large. The vehi-cle should not be driven. Call roadsideassistance to have the vehicle towed to aworkshop for inspection/replacement ofthe tire. Volvo recommends an authorizedworkshop.
11. Switch off the compressor and remove the electrical cable.
12. Unscrew the hose from the tire's valve and screw the valve cap back on.
NOTE
After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
13. Put the protective hose cover onto the
hose to help prevent leakage of any resid- ual sealing compound. Return the equip-ment to the cargo compartment.
14. Immediately drive the vehicle at least 3 km (2 miles) at a maximum speed of80 km/h (50 mph) to allow the sealingcompound to seal the tire, and thenrecheck the inflation pressure.
WARNING
During the tire's first revolution, some seal- ing compound may spray out of the punc-ture hole. Before driving away, make surethat no one is near the vehicle who couldbe sprayed with sealing compound. Makesure no one is within 2 meters(7 feet) ofthe vehicle.
15. Rechecking the inflation pressure Connect the hose to the tire's valve and screw the hose connector onto the valveas far as possible. The compressor mustbe switched off.

Determining the vehicle's permitted weight
Properly loading your vehicle will provide maximum return of vehicle design perform-ance.
Weight designationsBefore loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or without atrailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does notinclude passengers, cargo, or optional equip-ment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing,towbar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). Thesenumbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axlemust never exceed its maximum permissibleweight.

WHEELS AND TIRES
529
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passen- gers.
Steps for Determining Correct Load
Limit
1. Locate the statement "the combined weight of occupants and cargo shouldnever exceed XXX kg or XXX lbs." on yourvehicle's placard.
2. Determine the combined weight of the driver and passengers that will be riding inyour vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXXlbs.
4. The resulting figure equals the available amount of cargo and luggage loadcapacity. For example, if the "XXX"amount equals 1400 lbs. and there will befive 150 lb. passengers in your vehicle, theamount of available cargo and luggageload capacity is 650 lbs. (1400 - 750 (5 ×150) = 650 lbs.)
5. Determine the combined weight of lug- gage and cargo being loaded on the vehi-cle. That weight may not safely exceed theavailable cargo and luggage load capacitycalculated in Step 4. 6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo andluggage load capacity of your vehicle.WARNING
Exceeding the permissible axle weight, gross vehicle weight, or any otherweight rating limits can cause tire over-heating resulting in permanent defor-mation or catastrophic failure.
Do not use replacement tires withlower load carrying capacities than thetires that were original equipment onthe vehicle because this will lower thevehicle's GVW rating. Use only tireswith the correct load carrying capacity.Consult your Volvo retailer for informa-tion.
