Driving with a trailer (p. 483) Towing 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. The vehicle must be lifted onto a
tow truck and transported with all four wheels on
the bed or lifting platform of the truck (no wheels
may touch the road).
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.

NOTE Always remember to calibrate the Tire Pres-
sure Monitoring System when the wheels
have been changed or the tire inflation pres-
sure has been corrected according to the tire
pressure decal or tire inflation pressure table.
If correct reference values have not been set,
the system cannot issue low tire pressure
alerts correctly.
The vehicle must be stationary with the
engine running to access the calibration but-
ton and to start the calibration process.
WARNING
The exhaust gases contain carbon monoxide,
which is invisible and odorless but very poi-
sonous. For this reason, always perform the
calibration procedure outdoors or in a work-
shop with exhaust gas evacuation equipment.

MAINTENANCE AND SERVICE
}}
611
Periodic maintenance helps minimize
emissions
NOTE
Refer to your Service and Warranty Book-
let for a comprehensive service and main-
tenance schedule up to 240,000 km
(150,000 miles). This program contains
inspections and services necessary for
the proper function of your vehicle and
includes components that affect vehicle
emissions.
The Warranty and Service Records Infor-
mation booklet also contains detailed
information concerning the warranties
that apply to your vehicle.
On-board Diagnostic SystemOBD II is part of your vehicle's computerized
engine management system. It stores diagnostic
information about your vehicle's emission con-
trols. It can light the Check Engine light (MIL) if it
detects an emission control "fault." A "fault" is a
component or system that is not performing
within an expected range. A fault may be perma-
nent or temporary. OBD II will store a message
about any fault.
Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a
vehicle's OBD II system. The inspector can then
read "faults." In some states, this type of inspec-
tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection
for any of the following reasons:
If your Check Engine (MIL) light is lit, your
vehicle may fail inspection.
If your vehicle's Check Engine light was lit,
but went out without any action on your part,
OBD II will still have a recorded fault. Your
vehicle may pass or fail, depending on the
inspection practices in your area.
If you had recent service that required dis-
connecting the battery, OBD II diagnostic
information may be incomplete and "not
ready" for inspection. A vehicle that is not
ready may fail inspection.
How can I prepare for my next
OBD II
emission inspection?
If your Check Engine (MIL) light is lit or was
lit but went out without service, have your vehicle diagnosed and, if necessary, serviced
by a qualified Volvo technician.
If you recently had service for a lit Check
Engine light, or if you had service that
required disconnecting the battery, a period
of driving is necessary to bring the OBD II
system to "ready" for inspection. Two half-
hour trips of mixed stop-and-go/highway
driving are typically needed to allow OBD II to
reach readiness. Your Volvo retailer can pro-
vide you with more information on planning a
trip.
Maintain your vehicle in accordance with your
vehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervals
are described in your vehicle's Warranty and
Service Records Information booklet.
The following points can be carried out between
the normally scheduled maintenance services.
Each time the car is refueled:
Check the engine oil level.
Clean the windshield, windshield wipers,
headlights, and taillights.
