OFF ROAD
• Maximizes the vehicle's ability to traverse dif-
ficult terrain or poor roads.
In this mode, ground clearance 4
is high, steering
is light, and all-wheel drive and Hill Descent
Control are activated.
This drive mode is only available at low speeds,
up to 40 km/h (25 mph). If this speed is excee-
ded, Off road mode will be cancelled and AWD
mode will be activated instead.
All-wheel drive requires both the combustion and
electric motor to be in continuous operation,
which results in higher fuel consumption.
In Off road mode, a compass will be displayed
between the speedometer and the tachometer in
the instrument panel. The permissible speed
range will be shown in the speedometer.
This drive mode is optimized for maximum control
when driving at low speeds on very poor roads or
difficult terrain. It raises the chassis 4
, reduces
driveline throttle response, and locks the vehicle
in all-wheel drive. The Hill Descent Control func-
tion facilitates controlled driving on steep down-
grades.NOTE This drive mode is not designed to be used
for normal street driving.
NOTE
Due to the increased ground clearance, if the
OFF ROAD mode was selected when the
engine was switched off, the suspension will
lower when the engine is restarted.
CAUTION
Do not use the OFF ROAD drive mode when
towing a trailer without an electrical connec-
tion. This could result in damage to the pneu-
matic suspension system's bellows.
AWD
•
Improves the vehicle's traction and handling
by increasing all-wheel drive.
This drive mode locks the vehicle in all-wheel
drive. An optimal distribution between front and
rear axle torque helps provide the best possible
control, stability and traction, e.g. on slippery
roads or when towing a heavy trailer or another
vehicle. The AWD drive mode is always available
regardless of the hybrid battery's charge status. Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
In the other drive modes, the vehicle automati-
cally adapts the need for all-wheel drive accord-
ing to the road surface, and can activate the elec-
tric motor or start the combustion engine as nee-
ded.
POWER
•
Power mode is designed to provide sportier
driving characteristics and a faster accelera-
tion response.
This drive mode maximizes the combined power
from the combustion engine and the electric
motor by providing power to both the front and
rear wheels. Gear shifting will be faster and more
distinct and the transmission will prioritize gears
with a higher traction force. Steering response is
faster, suspension is stiffer and ground clearance
is lower 4
to help reduce body roll when cornering.
Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
This drive mode is optimized for maximum per-
formance and throttle response. It changes the
throttle response, gear shifting program and
turbo boost system. Chassis settings and steer-
ing and brake response are also optimized. The
Power drive mode is always available regardless
of the hybrid battery's charge status. 4
For vehicles with pneumatic suspension.

STARTING AND DRIVING
* Option/accessory.
450 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 level cannot be adjusted when any of the
side doors or the tailgate is open.
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.

* Option/accessory.
474 Trailer Stability Assist*
Trailer Stability Assist (TSA 8
) is a function
designed to help stabilize a vehicle that is tow-
ing a trailer when the vehicle and trailer have
begun to sway. The function is part of the Elec-
tronic Stability Control system ESC 9
.
Reasons for swayingA vehicle towing a trailer may begin to sway for
various reasons. Normally this only occurs at high
speeds. However, if the trailer is overloaded or
unevenly distributed, e.g. too far back, there is a
risk of swaying even at low speeds.
Swaying may be caused by factors such as:
• The vehicle and trailer are hit by a sudden,
strong crosswind.
• The vehicle and trailer are traveling on an
uneven road or over a bump.
• Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult or
impossible to stop it. This makes the vehicle and
trailer difficult to control and there is a risk of
swerving into oncoming traffic or driving off the
road.
Trailer Stability Assist functionTrailer Stability Assist continuously monitors the
vehicle's movements, particularly lateral move- ments. If swaying is detected, the brakes are
applied individually on the front wheels, which has
a stabilizing effect on the vehicle and trailer. This
is often enough to enable the driver to regain
control of the vehicle.
If the Trailer Stability Assist function's first
attempt is not adequate to stop the swaying
motion, the brakes are applied on all wheels and
engine power is temporarily reduced. As the
swaying motion begins to decrease and the vehi-
cle and trailer have once again become stable,
TSA stops regulating the brakes/engine power
and the driver regains control of the vehicle.
NOTE
Trailer Stability Assist is deactivated if the
driver selects the sport mode by deactivating
ESC in the center display's menu system. Trailer Stability Assist may not intervene if the
driver tries to compensate for the swaying motion
by moving the steering wheel rapidly, because
the system will then not be able to determine if it
is the trailer or the driver causing the swaying. When Trailer Stability Assist is
activated, the ESC symbol is
displayed in the instrument
panel.

476Towing using a towline
This section refers to one vehicle being towed
behind another using a towline.
Twin Engine vehicles may not be towed behind
another vehicle due to the risk of damage to the
electric motor. If the vehicle cannot be driven and
needs to be moved, it must be transported on a
tow truck with all four wheels on the bed of the
truck.
Towing another vehicleTowing another vehicle requires a lot of power -
use the AWD drive mode. This helps charge the
hybrid battery and improve the vehicle's driving
and roadholding characteristics.
Before towing another vehicle, check applicable
speed limit regulations.
Jump startingDo not tow the vehicle to start the engine. Use an
auxiliary battery if the start battery's charge level
is so low that the engine cannot be started.
CAUTION Attempts to tow-start the vehicle could cause
damage to the electrical drive motor and
three-way catalytic converter.

WHEELS AND TIRES

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.
