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 tem-
perature 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.
•Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.
•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.
•At highway driving speeds, fuel consump-
tion 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
intervals.
WARNING
Driving with the trunk open: Driving with
the trunk open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the trunk must be kept open for
any reason, proceed as follows:
1. Close the windows.
2. Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
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 cargo area, 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 the
"Tire pressure" section. Loads should be dis-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.
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.

06 Starting and driving
Rear park assist*
06

* Option/accessory, for more information, see Introduction.171 Introduction
Rear park assist
The park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in the rear bumper to measure the distance to
a vehicle, object or a person who may be close
to the rear of your vehicle.
WARNING
Park Assist is an information system, NOT a
safety system. This system is designed to
be a supplementary aid when parking the
vehicle. It is not, however, intended to
replace the driver's attention and judge-
ment.
Function
The system is activated automatically when the
vehicle is started. The indicator light in the but-
ton in the center console illuminates. Park
assist monitors the area behind the vehicle
when the engine is running and reverse gear
has been selected.
The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The signal comes
from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc., which could trigger the rear park
assist system's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.
Activating/deactivating park assist
G018389
Park Assist button (rear button in the illustration)
The system is activated automatically when the
vehicle is started.

Press the Park assist button on the center
console to temporarily deactivate the sys-
tem. The indicator light in the button will go
out when the system has been deacti-
vated.

Park assist will be automatically reactiva-
ted the next time the engine is started, or if
the button is pressed (the indicator light in
the button will illuminate).

07 Wheels and tires
Tire Sealing System*
07
194* Option/accessory, for more information, see Introduction.
Introduction
Location of the tire sealing system
Certain models are equipped with a tire sealing
system* that enables you to temporarily seal a
hole in the tread surface and re-inflate 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 socket is located in the front tunnel
console.
Accessing the tire sealing systemThe tire sealing system is stowed in the com-
partment in the rear side of the ski hatch in the
center of the rear seat backrest. See page
119 for information on opening this hatch.
1. Lift the floor hatch in the trunk.
2. Lift out the tire sealing system.
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.
•After use, stow the tire sealing system
properly to help prevent rattling.
WARNING
•After using the tire sealing system, the
vehicle should not be driven farther than
approximately 120 miles (200 km).
•Have the tire inspected by a trained and
qualified Volvo service technician as
soon as possible to determine if it can
be permanently repaired or must be
replaced.
•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.
