300 Driving and Operating
Trailer Weight Ratings
When towing a trailer, the
combined weight of the
vehicle, vehicle contents,
trailer, and trailer contents
must be below all of the
maximum weight ratings for
the vehicle, including:
.Gross Combined Weight
Rating (GCWR)
.Gross Vehicle Weight
Rating (GVWR)
.Maximum Trailer Weight
Rating
.Maximum Trailer Tongue
Weight Rating
.Gross Axle Weight
Rating-Rear (GAWR-RR)
See “Weight-Distributing Hitch
and Adjustment” under Towing
Equipment 0303 to determine
if equalizer bars are required
to obtain the maximum trailer
weight rating. See
“Trailer Brakes” under
Towing Equipment 0303 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
following.
Gross Vehicle Weight
Rating (GVWR)
For information about the
vehicle's maximum load
capacity, see Vehicle Load
Limits0202. When calculating
the GVWR with a trailer
attached, the trailer tongue

and the original equipment
tire size and recommended
inflation pressure. See“Tire
and Loading Information
Label” under Vehicle Load
Limits 0202.
Tire Pressure
Tires need the correct
amount of air pressure to
operate effectively.
{Warning
Neither tire underinflation
nor overinflation is good.
Underinflated tires,
or tires that do not have
enough air, can result in:
.Tire overloading and
overheating, which
could lead to a blowout
.Premature or
irregular wear
.Poor handling
(Continued)
Warning (Continued)
.Reduced fuel economy
for internal combustion
engine vehicles
.Reduced range for
electric vehicles
Overinflated tires, or tires
that have too much air,
can result in:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from
road hazards
The Tire and Loading
Information label on the
vehicle indicates the
original equipment tires
and the correct cold tire
inflation pressures. The
recommended pressure is
the minimum air pressure
needed to support the vehicle's maximum load
carrying capacity. See
Vehicle Load Limits
0202.
How the vehicle is loaded
affects vehicle handling
and ride comfort. Never
load the vehicle with more
weight than it was
designed to carry.
When to Check
Check the pressure of the
tires once a month or more.
How to Check
Use a good quality
pocket-type gauge to
check tire pressure. Proper
tire inflation cannot be
determined by looking at
the tire. Check the tire
inflation pressure when the
tires are cold, meaning the
vehicle has not been driven
for at least three hours or
no more than 1.6 km (1 mi).
