STARTING AND DRIVING
462Driving through standing water
Driving the vehicle through a deep pool of stand-
ing water on a water-covered roadway is called
fording. This must be done with great caution. To prevent damage to the vehicle when driving
through water (e.g. on flooded roads):
• Do not drive in water higher than the floor of
the vehicle. If possible, check the depth of
the water at its deepest point before driving
through it. Be particularly careful when driv-
ing through flowing water.
• Always select the Off Road drive mode
before driving in water to ensure the gasoline
engine is running.
• Do not drive faster than walking speed.
• Do not stop the vehicle in the water. Drive
carefully forward or back the vehicle out of
the water.
• Remember that waves created by passing
vehicles could cause the water level to rise
above the vehicle's floor level.
• Avoid driving through salt water to help avoid
the risk of corrosion.
CAUTION Parts of the vehicle (e.g. engine, transmission,
driveline, electrical components, etc.) can be
damaged if the vehicle is driven through water
higher than its floor level. Damage to any
components caused by flooding, vapor lock or
insufficient oil is not covered under warranty.
If the engine stalls while the vehicle is in
water, do not attempt to restart it. Have the
vehicle towed on the bed of a tow truck to a
workshop - an authorized Volvo workshop is
recommended.
When you have passed the water, press lightly on
the brake pedal and check that the brakes are
functioning properly. Water, mud, slush, etc. can
make the brake linings slippery, resulting in
delayed braking effect.
If the vehicle is equipped with a trailer coupling
contact, clean the contact after driving in water or
mud.

imprinted on the sidewall of the tire. The last four
digits in the series is the Department of
Transportation (DOT) stamp and indicates the
week and year the tire was manufactured. The
tire in the illustration has 0717 as the last four
digits, which means it was manufactured week 7
of 2017.
Tire ageTires degrade over time, even when they are not
being used. It is recommended that tires gener-
ally be replaced after 6 years of normal service.
Heat caused by hot climates, frequent high load-
ing conditions or Ultra Violet (U.V.) exposure can
accelerate the aging process. The temporary
spare
2
should also be replaced at 6-year inter-
vals, even if it has never been used. A tire with
e.g., visible cracks or discoloration should be
replaced immediately.
Tire economy
• Maintain correct tire pressure.
• Avoid fast starts, hard braking and tire
screeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very impor-
tant.
• Unbalanced wheels impair tire economy and
driving comfort. •
Tires must maintain the same direction of
rotation throughout their lifetime.
• When replacing tires, the tires with the most
tread should be mounted on the rear wheels
to reduce the chance of oversteer during
hard braking.
• Hitting curbs or potholes can damage the
tires and/or wheels permanently.
Tire rotationYour vehicle has no required tire rotation. Driving
style, tire pressure, climate and road conditions
affect how quickly the tires age and exhibit signs
of wear. Maintaining the correct tire pressure
helps keep tread wear evenly distributed.
To help prevent differences in tread depth and
wear patterns forming on the tires, the front and
rear wheels should be rotated, i.e. the front tires
moved to the rear and the rear tires moved to the
front. Ideally, tire rotation should be done the first
time after approximately 5000 km (ca
3100 miles) and thereafter at 10,000 km
(approx. 6200 miles) intervals.
If you have any questions regarding tread depth,
Volvo recommends consulting an authorized
Volvo workshop. If significant differences in wear
(> 1 mm difference in tread depth) between the
tires have already occurred, the least worn tires
should always be mounted on the rear wheels. A
front-wheel skid (understeer) is usually easier to control than a rear-wheel skid (oversteer). If the
front wheels skid, the vehicle will continue in a
straight line instead of the rear wheels skidding
to the side, which could cause you to completely
lose control of the vehicle. It is therefore impor-
tant that the rear wheels never lose grip before
the front wheels.
Storing wheels and tiresWhen storing complete wheels (tires mounted on
rims), they should be suspended off the floor or
placed on their sides on the floor.
Tires not mounted on rims should be stored on
their sides or standing upright, but should not be
suspended.
CAUTION
Tires should preferably be stored in a cool,
dry, dark place, and should never be stored in
close proximity to solvents, gasoline, oils, etc.

Periodic maintenance helps minimize
emissions
NOTE •
Refer to your Service and Warranty Book-
let for a comprehensive service and main-
tenance schedule up to 240,000 km
(150,000 miles). This program contains
inspections and services necessary for
the proper function of your vehicle and
includes components that affect vehicle
emissions.
• The Warranty and Service Records Infor-
mation booklet also contains detailed
information concerning the warranties
that apply to your vehicle.
On-board Diagnostic SystemOBD II is part of your vehicle's computerized
engine management system. It stores diagnostic
information about your vehicle's emission con-
trols. It can light the Check Engine light (MIL) if it
detects an emission control "fault." A "fault" is a
component or system that is not performing
within an expected range. A fault may be perma-
nent or temporary. OBD II will store a message
about any fault.
Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a
vehicle's OBD II system. The inspector can then
read "faults." In some states, this type of inspec-
tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection
for any of the following reasons:
• If your Check Engine (MIL) light is lit, your
vehicle may fail inspection.
• If your vehicle's Check Engine light was lit,
but went out without any action on your part,
OBD II will still have a recorded fault. Your
vehicle may pass or fail, depending on the
inspection practices in your area.
• If you had recent service that required dis-
connecting the battery, OBD II diagnostic
information may be incomplete and "not
ready" for inspection. A vehicle that is not
ready may fail inspection.
How can I prepare for my next
OBD II
emission inspection?
• If your Check Engine (MIL) light is lit - or was
lit but went out without service, have your vehicle diagnosed and, if necessary, serviced
by a qualified Volvo technician.
• If you recently had service for a lit Check
Engine light, or if you had service that
required disconnecting the battery, a period
of driving is necessary to bring the OBD II
system to "ready" for inspection. Two half-
hour trips of mixed stop-and-go/highway
driving are typically needed to allow OBD II to
reach readiness. Your Volvo retailer can pro-
vide you with more information on planning a
trip.
• Maintain your vehicle in accordance with your
vehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervals
are described in your vehicle's Warranty and
Service Records Information booklet.
The following points can be carried out between
the normally scheduled maintenance services.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers,
headlights, and taillights.

MAINTENANCE AND SERVICE
610Engine oil
For the recommended service intervals and war-
ranties to be applied, an approved engine oil
must be used. Volvo recommends: If the engine oil is not checked regularly and the
level becomes low, this could cause serious
engine damage.
CAUTION
To satisfy the requirements for the engine's
service intervals, all engines are factory-filled
with a specially adapted synthetic engine oil.
Great care has been put into the choice of oil,
with consideration given to service life, starta-
bility, fuel consumption and environmental
impact.
For the recommended service intervals to
apply, an approved engine oil must be used.
Only use the prescribed oil grade to top off or
change the oil. Otherwise, there is a risk of
the vehicle's service life, startability, fuel con-
sumption and environmental impact being
affected.
Failure to use engine oil of the prescribed
grade and viscosity could cause damage to
engine-related components. Volvo Car Corpo-
ration disclaims warranty liability for such type
of damage.
Volvo recommends entrusting oil changes to
an authorized Volvo workshop.
Volvo uses different systems to warn if the oil
level is too low/high or the oil pressure is low. On
engine variants with an oil pressure sensor, awarning symbol is displayed in the instrument
panel when oil pressure is low . On engine
variants with an oil level sensor, the warn-
ing symbol in the instrument panel and display
messages are used to alert the driver. Some
engine variants have both systems. Contact a
Volvo retailer for more information.
Change the engine oil and oil filter according to
the schedule specified in the Warranty and Main-
tenance Records Information booklet. Oils of a
higher grade than that specified may be used. If
the vehicle is driven in adverse conditions, Volvo
recommends using an oil with a higher grade
than that specified.

.
It may be necessary to top up engine oil between
regularly scheduled services.
No action is necessary with regard to engine oil
level until a message appears in the instrument
panel.
WARNING If this symbol is shown together
with the message
Engine oil level
Service required, visit a workshop – an authorized Volvo workshop is
recommended. The oil level may be too high.
CAUTION If this symbol is shown together
with a message about low oil level,
for example
Engine oil level low
Refill 1 liter, fill only with the indi-
cated volume, e.g. 1 liter (1 quart).
WARNING Do not spill oil on the hot exhaust pipes as
this could cause a fire.
Viewing oil level in the center displayThe oil level can be viewed using the electronic
oil level gauge in the center display once the
vehicle has been started. The oil level should be
checked regularly.
1.
Open the Car status app from App view in
the center display.
2. Tap Status to display the oil level. Oil level graphic in the center display.NOTE
The system cannot directly detect changes
when the oil is filled or drained. The vehicle
must have been driven approximately 30 km
(20 miles) and have been stationary
5 minutes on a level surface and with the
engine off before the correct oil level will be
displayed.

Coolant helps keep the combustion engine at
the right operating temperature. The heat trans-
ferred from the engine to the coolant can be
used to warm the passenger compartment.
When refilling coolant, follow the instructions on
the package. Never fill the cooling system with
only water. The risk of freezing is increased with
too low or too high amounts of coolant.
If there is coolant under the vehicle, smoke from
the cooling system, or if more than 2 liters (about
2 quarts) of coolant has been added to the sys-
tem, there could be something wrong with the
cooling system and starting the vehicle could
damage the engine. Call a tow truck and do not
attempt to start the engine.
WARNING The coolant may be very hot. Never unscrew
the cap when the coolant is hot. If coolant
must be filled, unscrew the expansion tank
cap slowly to relieve overpressure. Coolant expansion tank.
