High temperaturesIf the temperature in the passenger compartment
is very high, the camera/radar sensor will switch
off temporarily for approx. 15 minutes after the
engine is started to protect its electronic compo-
nents. When the temperature has cooled suffi-
ciently, the camera/radar sensor will automati-
cally restart.Damaged windshield
CAUTIONIf there are cracks, scratches or stone chips
on the windshield in front of any of the cam-
era and radar unit "windows" and this covers
an area of about 0.5 × 3.0 mm
(0.02 × 0.12 in.) or more, contact a workshop
to have the windshield replaced – an author-
ized Volvo workshop is recommended.
Failure to take action could result in reduced
performance for the driver support systems
that use the camera and radar unit.
It could cause functions to be reduced, deac-
tivated completely or produce an incorrect
function response.
To avoid the risk of loss of function, malfunc-
tion or reduced function of the driver support
systems that use the radar unit, the following
also apply:
Volvo advises against repairing cracks,
scratches or stone chips in the area in
front of the camera and radar unit – the
entire windshield should instead be
replaced.
Before replacing the windshield, contact
an authorized Volvo workshop to verify
that the right windshield has been
ordered and installed.
The same type of windshield wipers or
wipers approved by Volvo should be used
for replacement.
CAUTION If the windshield is replaced, the camera and
radar unit must be recalibrated by a workshop
to help ensure proper functioning of all of the
vehicle's camera and radar-based systems –
an authorized Volvo workshop is recom-
mended.

Ignition modes
The vehicle's ignition can be put in various
modes (levels) to make different functions availa-
ble.
To enable the use of a limited number of func-
tions when the engine is not running, the ignition
can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual.
The following table shows which functions are
available in each ignition mode: Mode
Functions
0 The odometer, clock and tem-
perature gauge are illuminated A
.
The power* seats can be
adjusted.
The power windows can be used.

II The headlights illuminate.
Warning/indicator lights illumi-
nate for 5 seconds.
A number of other systems are
activated. However, seat and rear
window heating can only be acti-
vated when the engine is running.
This ignition mode uses a lot of
current from the battery and
should be avoided whenever pos-
sible! A

Slippery driving conditionsFor optimal traction and roadholding, Volvo rec-
ommends using snow tires on all wheels when-
ever there is a risk of snow or ice on the road.
NOTECertain countries require use of winter tires
by law. Not all countries permit the use of
studded tires.
Practice driving on slippery surfaces under con-
trolled conditions to learn how the vehicle reacts.

Refilling coolant (p. 625) Driving 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.
CAUTION
Because it can be difficult to determine the
water depth, avoid driving through standing or
running water.
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.

the vehicle safely and letting the engine idle
for a few minutes to let the transmission
cool.
If the vehicle begins to overheat, the air con-
ditioning may be temporarily switched off.
After a prolonged period of driving in
demanding conditions, do not turn off the
engine immediately after stopping.
NOTE It is normal for the engine's cooling fan to
operate for a short time after the engine is
switched off.

Preparing for a long trip (p. 472) Battery drain
The electrical functions in the vehicle drain the
battery to varying degrees. Avoid using ignition
mode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain
power from the electrical system. Do not use
functions that use a lot of electrical current when
the engine is turned off. Examples of such func-
tions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is
shown in the driver display. The vehicle's energy-
saving function will then turn off or reduce certain
functions, such as the blower and/or the audio
system.
– Charge the battery by starting the engine
and let it run for at least 15 minutes (driving
charges the battery faster than letting the
engine idle).

MAINTENANCE AND SERVICE

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.
