Extended Parking
It is best not to park with the
vehicle running. If the vehicle is
left running, be sure it will not
move and there is adequate
ventilation.
See Shifting Into Park0263
and Engine Exhaust 0265.
If the vehicle is left parked and
running with the remote key
outside the vehicle, it will
continue to run for up to
15 minutes. If the vehicle is left parked and
running with the remote key
inside the vehicle, it will
continue to run for up to
30 minutes.
The vehicle could turn off
sooner if it is parked on a hill,
due to lack of available fuel.
The timer will reset if the
vehicle is taken out of P (Park)
while it is running.
Engine Exhaust
{
Warning
Engine exhaust contains
carbon monoxide (CO),
which cannot be seen or
smelled. Exposure to CO can
cause unconsciousness and
even death.
Exhaust may enter the
vehicle if:
.The vehicle idles in areas
with poor ventilation
(parking garages, tunnels, (Continued)

Trailer Towing
General Towing
Information
Only use towing equipment
that has been designed for the
vehicle. Contact your dealer or
trailering dealer for assistance
with preparing the vehicle to
tow a trailer. Read the entire
section before towing a trailer.
To tow a disabled vehicle, see

Driving
Characteristics and
Towing Tips
{Warning
You can lose control when
towing a trailer if the correct
equipment is not used or the
vehicle is not driven
properly. For example, if the
trailer is too heavy or the
trailer brakes are
inadequate for the load, the
vehicle may not stop as
expected. You and others
could be seriously injured.
The vehicle may also be
damaged, and the repairs
would not be covered by the
vehicle warranty. Pull a
trailer only if all the steps in
this section have been
followed. Ask your dealer for
advice and information
about towing a trailer with
the vehicle.
Driving with a Trailer
Trailering is different than just
driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
durability, and fuel economy.
Successful, safe trailering
takes correct equipment, and
it has to be used properly.
The following information has
many time-tested, important
trailering tips and safety rules.
Many of these are important
for your safety and that of
your passengers. Read this
section carefully before pulling
a trailer.
When towing a trailer:
.Become familiar with and
follow all state and local laws
that apply to trailer towing.
These requirements vary
from state to state.
.State laws may require the
use of extended side view
mirrors. If your visibility is
limited or restricted while

See“Weight-Distributing Hitch
Adjustment” under Towing
Equipment 0356 to determine
if equalizer bars are required
to obtain the maximum trailer
weight rating.
See “Trailer Brakes” under
Towing Equipment 0356 to
determine if brakes are
required based on the trailer
weight.
The only way to be sure the
weight is not exceeding any of
these ratings is to weigh the
tow vehicle and trailer
combination, fully loaded for
the trip, getting individual
weights for each of these
items.{Warning
You and others could be
seriously injured or killed if
the trailer is too heavy or
the trailer brakes are
inadequate for the load. The
vehicle may be damaged,
and the repairs would not be
covered by the vehicle
warranty.
Only tow a trailer if all the
steps in this section have
been followed. Ask your
dealer for advice and
information about towing a
trailer.
Gross Combined Weight
Rating (GCWR)
GCWR is the total allowable
weight of the completely
loaded vehicle and trailer
including any fuel, passengers,
cargo, equipment, and
accessories. Do not exceed
the GCWR for your vehicle.
The GCWR for the vehicle is
on the tow rating chart later in
this section.
To check that the weight of
the vehicle and trailer are
within the GCWR for the
vehicle:
1. Start with the curb weight from the Trailering
Information Label.
2. Add the weight of the trailer loaded with cargo
and ready for the trip.
