Towing using a towline
This section refers to one vehicle being towed
behind another using a towline.
Before towing another vehicle, check applica-
ble speed limit regulations.
Preparations and towing
CAUTION
Vehicles with the small gear selector can-
not shift out of the P position when the
engine is off. Contact an authorized Volvo
workshop or a professional towing com-
pany for assistance towing the vehicle.
CAUTION
Note that the vehicle must always be
towed with the wheels rolling forward.
Do not tow a vehicle with automatic
•
transmission at a speed greater than
80 km/h (50 mph) or for a distance
greater than 80 km (50 miles).
WARNING
Ignition mode II must be active – all
•
airbags are deactivated in ignition
mode I.
Always have the remote key in the
•
vehicle when it is towed.
WARNING
The brake and steering servos do not work
when the engine is off – it takes
about 5 times more pressure on the brake
pedal and steering requires much more
effort than normal.
1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.
3. Put the vehicle in ignition mode II – with-
out pressing the brake pedal, turn the start
knob clockwise and hold it there for about
4 seconds. Release the knob, which will
automatically return to its original position.
4. Move the gear selector to neutral (N) and
release the parking brake.
If the battery charge level is too low, it
may not be possible to release the parking
brake. Connect an auxiliary battery to the
vehicle if the battery is discharged.
