124 06 Starting and driving
Fuel requirements
Octane ratingMINIMUM
Volvo recommends premium for best performance, but using 87 octane or above will not affect engine reliability.
Volvo engines are designed to achieve rated horsepower, torque, and fuel economy performance using premium 91
octane fuel.RECOMMENDED
In demanding driving conditions, such as operating the vehicle in hot weather, towing a trailer, or driving for extended
periods at higher altitudes than normal, it may be advisable to switch to higher octane fuel (91 or higher) or to change
gasoline brands to fully utilize your engine's capacity, and for the smoothest possible operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be necessary to fill the tank more than
once before a difference in engine operation is noticeable.
Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your vehicle, lead has been strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you
live in an area where you must fill your own gas tank, take precautions. These may include:
standing upwind away from the filler nozzle while refueling
ProCarManuals.com

refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during
refueling
wearing neoprene gloves while handling a fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your vehicle's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.
125 06 Starting and driving
Refueling
WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the
vehicle to a trained and qualified Volvo service technician for correction.
WARNING
Driving with the trunk open: Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment.
If the trunk must be kept open for any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and blower control to its
highest setting.
Fuel filler door
Press the button on the light switch panel (see illustration on page 57) when the vehicle is at a standstill to unlock the
fuel filler door. Please note that the fuel filler door will remain unlocked until the vehicle begins to move forward. An
audible click will be heard when the fuel filler door relocks.
If you intend to leave your vehicle while it is being refueled, this feature enables you to lock the doors/trunk while
ProCarManuals.com

leaving the fuel filler door unlocked.
You can also keep the vehicle locked if you remain inside it during refueling. The central locking button does not lock
the fuel filler door. Be sure the fuel filler door is not obstructed and is completely closed after refueling.
Open the fuel filler cap slowly during hot weather.
NOTE
During a transitional period, a small number of service stations may still have fuel nozzles that are not compatible
with the fuel filler neck on vehicles equipped with the evaporative control system.
126 06 Starting and driving
Refueling
Refueling
The fuel tank is designed to accommodate possible expansion of the fuel in hot weather. See page 246
for fuel tank
volume. Be aware that the "usable" tank capacity will be somewhat less than the specified maximum. When the fuel
level is low, such factors as ambient temperature, the fuel's "Reid vapor pressure" characteristics, and terrain can affect
the fuel pump's ability to supply the engine with an adequate supply of fuel. Therefore, it is advisable to refuel as soon
as possible when the needle nears the red zone, or when the fuel warning light comes on.
CAUTION
Do not refuel with the engine running1. Turn the ignition off or to position I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place.1
Avoid overfilling the fuel tank. Do not press the handle on the filler nozzle more than one extra time. Too much
fuel in the tank in hot weather conditions can cause the fuel to overflow. Overfilling could also cause damage to the
emission control systems.
Avoid spilling gasoline during refueling. In addition to causing damage to the environment, gasolines containing
alcohol can cause damage to painted surfaces, which may not be covered under the New Vehicle Limited Warranty.
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under
the New Vehicle Limited Warranty.
1If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator
lamp) may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo original or approved fuel filler caps.
127 06 Starting and driving
Starting the vehicle
Starting the engine
1. Fasten the seat belt.
WARNING
ProCarManuals.com

Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Adjust the seat if necessary. See pages 92 and 94
.
2. Apply the parking brake (hand brake) if not already set. The gear selector (automatic transmission) is locked in the
( P )ark position ( SHIFTLOCK ). Manual transmission: the clutch must be fully depressed.
3. Without touching the accelerator pedal, turn the ignition key
1 to the starting position. Allow the starter to operate for
up to 10 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat this step.
1If two of the keys to your vehicle are close together, e.g. on the same key ring, when you try to start the vehicle, this could cause interference in
the immobilizer system and result in the vehicle not starting. If this should occur, remove one of the keys from the key ring before trying to start
the vehicle again.
NOTE
If the key blade section of the remote is not fully folded out when starting the vehicle, the immobilizer function
may make it impossible to start the engine.
After a cold start, idle speed may be noticeably higher than normal for a short period. This is done to help bring
components in the emission control system to their normal operating temperature as quickly as possible, which
enables them to control emissions and help reduce the vehicle's impact on the environment.
To release the gear selector from the P position, the engine must be running (or the ignition key must be in
position II) and the brake pedal must be depressed.
Select the desired gear. The gear engages after a very slight delay which is especially noticeable when selecting R.
NOTE
Your vehicle is equipped with a KEYLOCK system (automatic transmission). When the engine is switched off, the
gear selector must be in the P position before the key can be removed from the ignition switch.
When starting in cold weather, the transmission may shift up at slightly higher engine speeds than normal until the
automatic transmission fluid reaches normal operating temperature.
WARNING
An extra mat on the driver's floor can cause the accelerator pedal to catch. Check that the movement of the
accelerator pedal is not impeded. No more than one protective floor covering may be used at one time.
WARNING
Always place the gear selector in Park or in reverse on models with a manual transmission, and apply the parking
brake before leaving the vehicle. Never leave the vehicle unattended with the engine running.
Always open garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The exhaust
gases contain carbon monoxide, which is invisible and odorless but very poisonous

Automatic transmission
The engine should be idling when you move the gear selector. Never accelerate until after you feel the transmission
engage! Accelerating immediately after selecting a gear will cause harsh engagement and premature transmission
wear.
Selecting P or N when idling at a standstill for prolonged periods of time will help prevent overheating of the
automatic transmission fluid.
Do not race a cold engine immediately after starting.
Ignition switch and steering wheel lock
1The gear selector must be in the (P)ark position (automatic transmission).
2 Please be aware that leaving the key in this position will increase battery drain.
WARNING
Never turn the key to position O while driving or when the vehicle is being towed.
Steering wheel lock
The steering wheel lock might be under tension when the vehicle is parked.
Turn the steering wheel slightly to free the ignition key.
In order to help reduce vehicle theft, make sure the steering wheel lock is engaged before leaving the vehicle.
WARNING
ProCarManuals.com

Never switch off the ignition (turn the ignition key to position 0) or remove the key from the ignition switch while
the vehicle is in motion. This could cause the steering wheel to lock, which would make the vehicle impossible to
steer.
129 06 Starting and driving
Economical driving
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the vehicle for driving short distances. This does not allow the engine to reach
normal operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the vehicle.
Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that roof racks, ski racks, etc, increase air resistance and also fuel consumption.
Avoid using automatic transmission kickdown feature unless necessary.
However, at higher driving speeds, fuel consumption will be lower with the air conditioning on and the windows
closed than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment. Some of the above mentioned items and others are checked at the standard
Maintenance Service intervals.
NOTE
Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using "kickdown"
to help improve fuel economy.
CAUTION
Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the engine could
result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper than 1 foot
(300 mm).
130 06 Starting and driving
Handling and road holding
ProCarManuals.com

Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend.
This ensures good stability and reduces the risk of rear wheel skid. Remember that these properties can alter with the
vehicle load.
The heavier the load in the trunk (max. 220 lbs, 100 kg), the less the tendency to understeer.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
the recommended pressure according to the vehicle load. See "Tire pressure" section.
Loads should be distributed so that capacity weight or maximum permissible axle loads are not exceeded.
Speed-sensitive power steering (Option on certain models)
With this feature, the steering is most responsive at lower speeds to make parking, driving in city traffic, etc., easier.
The effect of the power steering diminishes as you accelerate for greater stability at highway speeds.
Driving through water
The vehicle can be driven through water up to a depth of approximately 9 in. (25 cm), at a maximum speed of 6 mph
(10 km/h).
Take particular care when driving through flowing water.
Clean the electrical connections for trailer wiring after driving in mud or water.
When driving through water, maintain low speed and do not stop in the water.
WARNING
After driving through water, press lightly on the brake pedal to ensure that the brakes are functioning normally.
Water or mud can make the brake linings slippery, resulting in delayed braking effect.
CAUTION
Engine damage will occur if water is drawn into the air cleaner.
If the vehicle is driven through water deeper than 9 in (25 cm), water may enter the differential and the
transmission. This reduces the oil's lubricating capacity and may shorten the service life of these components.
Do not allow the vehicle to stand in water up to the door sills longer than absolutely necessary. This could result
in electrical malfunctions.
If the engine has been stopped while the car is in water, do not attempt to restart the engine. Have the car towed
out of the water.
131 06 Starting and driving
Manual transmission
ProCarManuals.com

6-speed manual transmission (option on certain models)
Depress the clutch pedal completely when changing gears1.
Remove your foot from the clutch pedal while driving. The shift pattern should be followed.
Fifth and sixth gears should be used as often as possible to help improve fuel economy.
1Clutch interlock
The clutch must be fully depressed before you can start your vehicle. If the clutch is not depressed, it will not be possible to start the engine.
WARNING
An extra mat on the driver's floor can cause the accelerator pedal and/or the clutch pedal to catch. Check that the
movement of these pedals is not impeded. Not more than one protective floor covering may be used at one time.
Engaging reverse gear
Never engage R while the vehicle is moving.
CAUTION
Be careful to avoid inadvertently engaging reverse while moving forward.
