147 To start the engine
WARNING
Before starting, check that the seat, steering
wheel and mirrors are adjusted properly.
Make sure the brake pedal can be
depressed completely. Adjust the seat if
necessary.
1. Fasten the seat belt.
2. Apply the parking brake if not already set.
The gear selector should be locked in the
Park (P) position (Shiftlock). See also page
152.
NOTE
After a cold start, idle speed may be notice-
ably higher than normal for a short period.
This is done to help bring components in the
emission control system to their normal
operating temperature as quickly as possi-
ble, which enables them to control emis-
sions and help reduce the vehicle's impact
on the environment.
3. The vehicle is equipped with an autostart
feature. Without touching the throttle
pedal, turn the key to position III and
release it. The starter motor will then oper-ate automatically (for up to ten seconds)
until the engine starts. If the engine fails to
start, repeat this step.
4. To release the gear selector from the Park
(P) position, the engine must be running (or
the ignition key must be in position II) and
the brake pedal must be depressed.
5. Select the desired gear. The gear engages
after a very slight delay, which is especially
noticeable when selecting R.
NOTE
•Immobilizer: If two of the keys to your
vehicle are close together, e.g., on the
same key ring when you try to start the
vehicle, this could cause interference in
the immobilizer system and result in the
vehicle not starting. If this should occur,
remove one of the keys from the key
ring before trying to start the vehicle
again.
•Keylock: The automatic transmission
has a keylock system. When the engine
is switched off, the gear selector must
be in the Park (P) position before the key
can be removed from the ignition
switch
1.
•When starting in cold weather, an auto-
matic transmission may shift up at
slightly higher engine speeds than nor-
mal until the automatic transmission
fluid reaches normal operating tem-
perature.
•Do not race a cold engine immediately
after starting. Oil flow may not reach
some lubrication points fast enough to
prevent engine damage.
1The optional keyless drive start control does not need to be removed from the ignition switch.

157 Dynamic Stability Traction Control
(DSTC)
The stability system consists of a number of
functions designed help reduce wheel spin,
counteract skidding, and to generally help
improve directional stability.
A pulsating sound will be audible when the
system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel
spin by transferring power from a drive wheel
that begins to lose traction to the wheel on the
opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of the stability system's permanent
functions and cannot be switched off.

Thumb wheel
RESET button
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
Temporarily switching off Spin control1. Turn the thumbwheel (A) on the left-side
steering wheel lever until the DSTC menu
is displayed.
2.
Hold down the RESET button (B) to toggle
between
DSTC ON or DSTC SPIN
CONTROL OFF.
NOTE
•The message DSTC SPIN CONTROL
OFF indicates that the stability sys-
tem's spin control function has tempo-
rarily been switched off.
•The spin control function is automati-
cally enabled each time the engine is
started.
•DSTC ON indicates that all system
functions are active.
Active yaw control – AYC (DSTC only)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.
This is one of the stability system's permanent
functions and cannot be switched off.

Symbols used by the stability system
Stability system indicator light
Information symbol
If the and symbols light up at the same
time, read the message in the display.
If only the
symbol lights up, this indicates
one of the following situations:
•The light illuminates for approximately
2 seconds to indicate that the system is
performing a self-diagnostic test when the
engine is started.
•If the light flashes while driving, this indi-
cates that the stability system is actively
functioning to help counteract wheel spin
and/or a skid.
•If this light stays on after the engine has
started or comes on while driving, there
may be a fault in the stability system. Con-
sult a trained and qualified Volvo service
technician.
•If Spin control has been intentionally
switched off, a message will be displayed.
WARNING
The stability system is intended to help
improve driving safety. It supplements, but
can never replace, the driver's judgement
and responsibility when operating the vehi-
cle. Speed and driving style should always
be adapted to traffic and road conditions.

towing eyelet on the front bumper by pry-
ing open the lower edge with a coin, etc.
Remove the cover over the opening for the
towing eyelet on the rear bumper by press-
ing the lower right corner of the cover.
Screw the towing eyelet in place first by
hand and then using the tire iron until it is
securely in place.After the vehicle has been towed, the eyelet
should be removed and returned to the tool
bag.
WARNING
Do not use the towing eyelets to pull the
vehicle up onto a flat bed tow truck.
Towing a vehicle with all four wheels on
the ground
WARNING
Volvo does not recommend towing a disa-
bled vehicle behind another vehicle. Signif-
icant difficulty in steering and braking, com-
bined with unfavorable weather, traffic, and
road conditions may make it impossible to
maintain vehicle control.
1. Apply the parking brake.

WARNING
Towing a vehicle with a locked steering
wheel will make the vehicle impossible to
steer.
2. Insert the key into the ignition to unlock the
steering wheel. The steering wheel must be
unlocked. With the engine off and the vehi-
cle at a standstill, great effort will be
required to turn the steering wheel.
3.
Turn the ignition key to position II.
4. Place the gear selector in neutral. For vehi-
cles with automatic transmissions, follow
instruction on page 152, "Shiftlock over-
ride" to allow the gear selector to be moved
from the Park position.
5. Keep firm pressure on the brake pedal
while releasing the parking brake.
6. When towing has been completed, return
the gear selector to Park and apply the
parking brake.
The following points should also be
observed:
•Never exceed 50 mph (80 km/h). Never
exceed local towing speed limits and heed
all local towing restrictions.
•Never tow farther than 50 miles (80 km).
•Keep the tow rope taut at all times while the
vehicle is in motion.
•The disabled vehicle should be towed in
the forward direction only.
WARNING
•Never allow a vehicle to be towed with-
out a driver behind the wheel of the dis-
abled vehicle.
•Never remove the key from the ignition
while the vehicle is moving. The steering
wheel could lock, making it impossible
to steer the vehicle.
•When the engine is not running, steering
resistance and the effort needed to
apply the brakes will be great.
•Never attempt to tow a vehicle with a
dead battery at night.
CAUTION
•Check with state and local authorities
before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing
device, lighting, marker flags, etc.
•Never attempt to push- or tow-start a
vehicle with a dead battery. This would
inject unburned fuel into the three-way
catalytic converter(s), causing over-
heating, backfiring, and damage, see
page 162 for instructions on jump star-
ting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equip-
ment for towing vehicles with front wheel drive.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle.
In this case, the vehicle should be towed with
the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.

•Sling-type equipment applied at the front
will damage radiator and air conditioning
lines.
•It is equally important not to use sling-type
equipment at the rear or apply lifting equip-
ment inside the rear wheels; serious dam-
age to the rear axle may result.
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be used
to secure the vehicle on the flat bed. Con-
sult the tow truck operator.
WARNING
•Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but con-
siderably higher pressure will be
required on the brake pedal and greater
steering effort must be exerted.
•The towing eyelets must not be used for
pulling the vehicle out of a ditch or for
any similar purpose involving severe
strain. Do not use the towing eyelets to
pull the vehicle up onto a flat bed tow
truck.

06 Starting and driving
Towing a trailer
06

163 General information
•Volvo recommends the use of Volvo trailer
hitches that are specially designed for the
vehicle.
Maximum trailer weights recommended by
Volvo are:
•Trailers without brakes: 1,540 lbs
(700 kg).
•Trailers with brakes: 2,000 lbs (900 kg)
Observe the legal requirements of the
state/province in which the vehicles are
registered.
•The maximum recommended hitch
tongue load is 165 lbs (75 kg).
•All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. Trailer hitch installation should not
interfere with the proper operation of this
bumper system.
Trailer towing does not normally present any
particular problems, but take into considera-
tion:
•Increase tire pressure to recommended
full. See the chapter "Wheels and tires."
•When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•Maximum speed when towing a trailer:
50 mph (80 km/h).
•Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watched
when driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
enters the red range.
•If the automatic transmission begins to
overheat, a message will be displayed in
the information display.
•Avoid overload and other abusive opera-
tion.
•Hauling a trailer affects handling, durabil-
ity, and economy.
•It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
•Do not connect the trailer's brake system
directly to the vehicle's brake system.
•More frequent vehicle maintenance is
required.
•Remove the ball and drawbar assembly
when the hitch is not being used.
•Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.
WARNING
•Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•Trailer hitches attaching to the vehicle's
rear axle must not be used.
•Never connect a trailer's hydraulic
brake system directly to the vehicle
brake system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult your nearest trained
and qualified Volvo service technician
for correct installation.
•When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.
