TOWING A TRAILER
WARNING: Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label.
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 325).
Some vehicles may have the
ability to modify trailer towing
features. See Towing (page
285).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop and load
capacity. When both the
loaded vehicle and trailer are
connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
279).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

4. You can attempt to start the vehicle
by pressing the brake pedal and
START/STOP, or press START/STOP
without pressing the brake pedal.
5. If the vehicle does not start, repeat steps 1 through 4.
JUMP STARTING THE VEHICLE WARNING:
Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide correct ventilation. WARNING:
Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately. WARNING:
Use only adequately
sized cables with insulated clamps.
Note: To avoid reverse polarity connections,
make sure that you correctly identify the
positive (+) and negative (-) terminals on
both the disabled and booster vehicles
before connecting the cables. Stay clear of
moving parts.
Preparing Your Vehicle
Do not attempt to push-start your
automatic transmission vehicle. Note:
Attempting to push-start a vehicle
with an automatic transmission may cause
transmission damage.
Note: Use only a 12-volt supply to start your
vehicle.
Note: Do not disconnect the battery of the
disabled vehicle as this could damage the
vehicle electrical system.
Park the booster vehicle close to the hood
of the disabled vehicle, making sure the
two vehicles do not touch.
Connecting the Jumper Cables WARNING:
Do not connect the
negative jumper cable to any other part
of your vehicle. Use the ground point.
Note: Do not attach the end of the positive
cable to the studs or L-shaped eyelet
located above the positive (+) terminal of
your vehicle ’s battery. High current may flow
through and cause damage to the fuses.
Note: In the illustration, the bottom vehicle
represents the booster vehicle.
