Red Key - restricted remote key*
A Red Key makes it possible for the vehicle
owner to set limitations for certain vehicle prop-
erties. The limitations are intended to promote
safe use of the vehicle, e.g. when it is loaned
out. For a Red Key, it is possible to define the vehi-
cle's maximum speed, set speed reminders and
limit the audio system's volume. Several of the
driver support systems will also always be active.
Otherwise, the Red Key functions in the same
way as a standard remote key.
One or more Red Key can be ordered from a
Volvo retailer. A total of twelve keys can be pro-
grammed and used for the same vehicle. Up to
ten may be restricted keys, but at least two must
be standard remote keys.
These restrictions are intended to help reduce
the risk of accidents and help the driver feel more secure when handing over the vehicle to e.g. a
young driver, parking attendant or workshop. The
settings for a Red Key cannot be changed by its
user; a regular remote key is needed to change
settings.

STARTING AND DRIVING
* Option/accessory.
434 Starting the vehicle
The vehicle can be started using the start knob
in the tunnel console when the remote key is in
the passenger compartment. Start knob in the tunnel console.
WARNING
Before starting:
Buckle your seat belt.
Adjust the seat, steering wheel and mir-
rors.
Make sure you can fully depress the
brake pedal. The remote key is not physically used to start the
ignition because the vehicle is equipped with the
keyless Passive Start system.
To start the vehicle:
1.

The remote key must be inside the vehicle.
For vehicles with Passive Start, the key must
be in the front section of the passenger
compartment. With the optional keyless lock-
ing/unlocking function*, the key can be any-
where in the vehicle.
2. Press and hold down the brake pedal 1
as far
as possible.
3. Turn the start knob clockwise and release. The control will automatically return to the
original position.
WARNING
Never use more than one inlay mat at a
time on the driver's floor. If any other type
of floor mat is used, remove the original
mat from the driver's seat floor before
driving. All types of mats must be securely
anchored in the attachment points in the
floor. Make sure the floor mat does not
impede the movement of the brake pedal
or accelerator pedal in any way, as this
could be a serious safety hazard.
Volvo's floor mats are specially manufac-
tured for your vehicle. They must be prop-
erly secured in the attachment points in
the floor to help ensure they cannot slide
and become trapped under the pedals.
The starter motor will crank until the engine
starts or until overheating protection is triggered.
During normal start conditions, the vehicle's elec-
tric motor will be prioritized and the gasoline
engine will remain off. This means that once the
start knob is turned clockwise, the electric motor
has been "started" and the vehicle is ready to be
driven. The warning and information symbols in
the instrument panel will go out and the selected
theme will be displayed to indicate that the elec-
tric motor is activated. 1
If the vehicle is moving, it is only necessary to turn the start knob cl\
ockwise to start the engine.

Leveling control* and suspension
The vehicle's leveling control system adjusts the
suspension and shock absorbers automatically
to help provide good comfort and control while
driving. Leveling can also be controlled manually
to facilitate loading or getting in and out of the
vehicle.
Pneumatic suspension and shock
absorbers
The system is adapted to the selected drive
mode and vehicle speed. The pneumatic suspen-
sion reduces the vehicle's ground clearance at
higher speeds to reduce air resistance and
increase stability. The shock absorbers are nor-
mally set to provide the best possible comfort
and are adjusted continuously according to the
road surface and the vehicle's acceleration, brak-
ing and cornering. The instrument panel indicates
when the suspension level is
being adjusted.The following apply if a door or the tailgate is
opened:
If a door is opened, the level can only be
adjusted upwards.
If the tailgate is open, the level can only be
adjusted downwards.
ParkingWhen parking, make sure that there is adequate
space above and below the vehicle since ground
clearance may vary depending on e.g. ambient temperature, how the vehicle is loaded, if loading
mode is used, which drive mode is selected after
the engine is started, etc.
The level may also be adjusted a period after the
vehicle is parked. This is to compensate for any
height changes that may occur due to tempera-
ture changes in the air springs when the vehicle
cools.
TransportingWhen transporting the vehicle on a ferry, train or
truck, only secure (lash) the vehicle around the
tires, not using any other parts of the chassis.
Changes in the pneumatic suspension may occur
during transport, which could adversely affect the
lashing and result in damage.

Jump starting using another battery
If the start battery is discharged, current from
another battery can be used to start the vehicle. Jumper cable connecting points.
CAUTION
The charging point of the vehicle is only
intended for jump starting the vehicle in ques-
tion. The charging point is not intended for
jump-starting another vehicle. Using the
charging point to start another vehicle could
cause a fuse to blow, which would cause the
charging point to stop working.
If a fuse has blown, 12 V Battery Fuse failure
Service required will be displayed in the instru-
ment panel. Volvo recommends contacting an
authorized Volvo workshop. To avoid short circuits or other damage, the fol-
lowing steps are recommended when jump star-
ting the battery:
1.
Put the ignition in mode 0.
2.
Make sure the auxiliary battery (the battery
used to jump start the discharged battery)
has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and make sure
that the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliary battery's positive (+) terminal (1).
CAUTION Connect the jump cable carefully to prevent
short circuits with other components in the
engine compartment.
5. Fold back the cover over your vehicle's posi-
tive (+) jump start terminal (2).
6.

Clamp the other end of the red jumper cable
to your vehicle's positive (+) jump start termi-
nal (2).
7. Clamp the black jumper cable onto the auxili- ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) ground
point (4). 9. Make sure the jumper cables are securely
attached to help prevent sparks while jump
starting.
10. Start the engine of the assisting vehicle and let it run for a few minutes at a higher idling
speed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the engine does not start, allow an additional 10
minutes of charging time and then try to start
the engine again.
NOTE When the engine is started under normal
conditions, the vehicle's electrical drive motor
is prioritized – the gasoline engine remains
off. This means that the electric motor has
"started" and the vehicle is ready to be driven
once the start knob has been turned clock-
wise. Start of the electric motor is indicated
by the indicator lights on the instrument panel
going out and its preselected theme illuminat-
ing.
CAUTION
Do not touch the connections between the
cable and the vehicle during the start attempt.
Risk of sparking.

Driving with a trailer (p. 483)
Towing capacity and tongue weight (p. 670) Driving with a trailer
There are a number of things to consider when
towing a trailer, such as the towbar, the trailer
and how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehi-
cle's curb weight. The total weight of all passen-
gers and any installed accessories, e.g. towbar,
reduces the vehicle's load-carrying capacity by
the corresponding amount.
Towbars used on the vehicle must be
approved for the applicable use.
Distribute the load on the trailer so that the
weight on the towbar complies with the
specified maximum towball weight. The
tongue weight is calculated as part of the
vehicle's payload.
Increase the tire pressure to the recom-
mended pressure for a full load.
The engine is subjected to more load than
usual when towing a trailer.
Towing a trailer affects the vehicle's han-
dling, durability and driving economy.
Do not drive with a heavy trailer when the
vehicle is very new. Wait until the mileage
has reached at least 1000 km (620 miles).
On long and steep downgrades, the vehicle's
brakes are subjected to much more load
than usual. When manually shifting, down-
shift and adapt speed accordingly.
