{Warning
Batteries can hurt you. They can
be dangerous because:
. They contain acid that can
burn you.
. They contain gas that can
explode or ignite.
. They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you.
Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
1. Check the other vehicle. It must have a 12-volt battery
with a negative ground system.
Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. If the vehicle is equipped with dual batteries, do not use the
driver-side auxiliary battery to
jump start the vehicle. This can
cause damage to the vehicle’s electrical system and
accessories. Always use the
passenger side battery in the
rear of the engine compartment
for jump starting.
3. Get the vehicles close enough so the jumper cables can
reach, but be sure the vehicles
are not touching each other.
If they are, it could cause an
unwanted ground connection.
You would not be able to start
your vehicle, and the bad
grounding could damage the
electrical systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put the automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking
brake. For vehicles with
four-wheel drive with an
N (Neutral) transfer case
position, be sure the transfer
case is in a drive gear —not
N (Neutral).

recreational vehicle towing are
dinghy and dolly towing. Dinghy
towing is towing the vehicle with all
four wheels on the ground. Dolly
towing is towing the vehicle with two
wheels on the ground and two
wheels on a dolly.
Follow the tow vehicle
manufacturer’s instructions. See
your dealer or trailering professional
for additional advice and equipment
recommendations.
Here are some important things to
consider before recreational vehicle
towing:
. Before towing the vehicle,
become familiar with the local
laws that apply to recreational
vehicle towing. These laws may
vary by region.
. What is the towing capacity of
the towing vehicle? Be sure to
read the tow vehicle
manufacturer's
recommendations. .
What is the distance that will be
traveled? Some vehicles have
restrictions on how far and how
long they can tow.
. Is the proper towing equipment
going to be used? See your
dealer or trailering professional
for additional advice and
equipment recommendations.
. Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Caution
Use of a shield mounted in front
of the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would
not be covered by the vehicle
warranty. If using a shield, only
use one that attaches to the
towing vehicle.
Dinghy Towing
Two-Wheel-Drive Vehicles
Caution
If the two-wheel-drive vehicle is
towed with all four wheels on the

components could be damaged.
The repairs would not be covered
by the vehicle warranty.
Two-wheel-drive vehicles should not
be towed with all four wheels on the
