potentially may need correcting. When this happens, please have your car checked by a Volvo retailer as soon as
possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice a change in your car's behavior.
Even so, an uncorrected condition could hurt fuel economy, emission cleanliness, and driveability. Extended driving
without correcting the cause could even damage other components in your car.

It may be necessary to deactivate one or both of the park assist systems in certain cases.
· Rear park assist: towing a trailer, carrying bicycles in a rear-mounted carrier, etc, could trigger the rear park assist
system's sensors.

could trigger the system's sensors.
Faults in the system
If a fault should occur in the system, the LED in the button will be switched off and a message will be displayed in the
text window.

For the system to function properly, the sensors in the front and/or rear bumpers should be kept clean. They can be
cleaned with car washing detergent and a sponge.
WARNING!
These systems are designed to be a supplementary aid when parking the vehicle. They are not, however, intended to
replace the driver's attention and judgement.
pg. 84 Driving economy
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 car 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 car.
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.
Avoid using the air conditioning when it is not required. When engaged, the A/C compressor places an additional
load on the engine. 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.
