Supplemental Restraint System (SRS)
G027284
SRS warning light
As an enhancement to the three-point seat
belts, your Volvo is equipped with a Supple-
mental Restraint System (SRS). Volvo's SRS
consists of seat belt pretensioners, front air-
bags, side impact airbags, the occupant
weight sensor, and inflatable curtains. All of
these systems are monitored by the SRS con-
trol module. An SRS warning light in the instru-
ment panel (see the illustration) illuminates
when the ignition key is turned to position I, II,
or III, and will normally go out after approxi-
mately 7 seconds if no faults are detected in
the system.Where applicable, a text message
will also be displayed when the
SRS warning light illuminates. If
this warning symbol is not func-
tioning properly, the general warn-
ing symbol illuminates and a text message will
be displayed.
WARNING
•If the SRS warning light stays on after
the engine has started or if it illuminates
while you are driving, have the vehicle
inspected by a trained and qualified
Volvo service technician as soon as
possible.
•Never try to repair any component or
part of the SRS yourself. Any interfer-
ence in the system could cause mal-
function and serious injury. All work on
these systems should be performed by
an authorized Volvo service technician.
WARNING
If your vehicle has been subjected to flood
conditions (e.g. soaked carpeting/standing
water on the floor of the vehicle) or if your
vehicle has become flood-damaged in any
way, do not attempt to start the vehicle or
put the key in the ignition before discon-
necting the battery (see below). This may
cause airbag deployment which could result
in personal injury. Have the vehicle towed to
a trained and qualified Volvo service tech-
nician for repairs.
Automatic transmission:
Before attempting to tow the vehicle, use
the following procedure to override the
shiftlock system to move the gear selector
to the neutral position:
1. Switch off the ignition for at least
10 minutes and disconnect the battery.
2. Wait at least one minute.
3. Insert the key in the ignition and turn it
to position II
4. Press firmly on the brake pedal.
5.
Move the gear selector from P (Park) to
the N(Neutral) position.

The climate system blower will be automati-
cally switched off when the engine is not run-
ning (even if the ignition key is in position I or
II) to avoid unnecessary battery drain. To acti-
vate the blower, turn the control to the desired
setting.
The climate system blower may start automat-
ically during a period of up to approximately
50 minutes after the ignition has been turned
off to remove condensation in the A/C evapo-
rator. It will run for 15 minutes and switch off
automatically.
Passenger compartment blower
Approximately 50 minutes after the ignition is
turned off, the blower may come on automati-
cally, and run for seven minutes, to remove
condensation in the A/C evaporator.
Blower function to reduce battery drain
The climate system's blower functions nor-
mally while the engine is running.
However, when the engine is switched off
(even if the ignition is switched to positions I or
II), the blower control will be automatically
switched off to avoid unnecessary battery
drain.The following points pertain if the ignition is on
but the engine in not running:
•To restart the blower, turn the control knob
to the setting of your choice.
•After approximately 2 minutes, the blower
speed will be reduced to avoid battery
drain.
You can reset the blower speed at any time.
Please be aware that the system has been
designed to reduce the blower's speed again
after 2 minutes, until the engine is started.
If the battery becomes drained:
•LOW BATTERY, FAN IS REDUCED will
be displayed in the text window in the
instrument panel.
•The yellow warning light in the instrument
panel (see page 54) will also light up.

WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment.
•If the tailgate 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 win-
dows and blower control to its highest
setting.
Weight distribution affects handlingAt 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, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommendedpressure 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.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:
•When the engine is not running, avoid turn-
ing the ignition key to position II (see
page 137). Many electrical systems (the
audio system, the optional infotainment/
navigation systems, power windows, etc)
will function with the ignition key in position
I. This position reduces drain on the bat-
tery.
•Please keep in mind that using systems,
accessories, etc that consume a great deal
of current when the engine is not running
could result in the battery being completely
drained.
NOTE
A warning message will be displayed in the
text window in the instrument panel when
the battery charge is low.

Battery maintenance
The battery in your vehicle is located under the
floor of the cargo compartment.
Driving habits and conditions, climate, the
number of starts, etc. all affect the service life
and function of the battery. In order for your
battery to perform satisfactorily, keep the fol-
lowing in mind:
•Use a screw driver to open the caps or
cover and a flashlight to inspect the level.
•If necessary, add distilled water. The level
should never be above the indicator.
•The fluid level should be checked if the
battery has been recharged.
•After inspection, be sure the cap over each
battery cell or the cover is securely in
place.
•Check that the battery cables are correctly
connected and properly tightened.
•Never disconnect the battery when the
engine is running, or when the key is in the
ignition. This could damage the vehicle's
electrical system.
•The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
•To help keep the battery in good condition,
the vehicle should be driven for at least 15minutes a week or connected to a charger
with an automatic charging function.
•If the battery is fully discharged a number
of times, this may shorten its service life.
Keeping the battery fully charged helps
prolong its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.
