320 DRIVING AND OPERATING
allowable tongue weight for the
vehicle or 227 kg (500 lb), whichever
is less.
Ask your dealer for trailering
information or assistance.
Towing Equipment
Hitches
Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going by, and
rough roads can affect the trailer and
the hitch.
Never attach rental hitches or other
bumper-type hitches. Only use
frame-mounted hitches that do not
attach to the bumper.
Always seal any holes in your vehicle
if the trailer hitch removed. If not
sealed, dirt, water, and carbon
monoxide (CO) from the exhaust may
enter your vehicle. SeeEngine Exhaust
0 241.
Consider using mechanical sway
controls with any trailer. Ask a
trailering professional about sway controls or refer to the trailer
manufacturer's recommendations and
instructions.
Tires
.Do not tow a trailer while using a
compact spare tire on the vehicle.
.Tires must be properly inflated to
support loads while towing a trailer.
See
Tires 0363 for instructions on
proper tire inflation.
Safety Chains
Always attach chains between the
vehicle and the trailer, and attach the
chains to the holes on the trailer hitch
platform. Instructions about safety
chains may be provided by the hitch
manufacturer or by the trailer
manufacturer.
Cross the safety chains under the
tongue of the trailer to help prevent
the tongue from contacting the road if
it becomes separated from the hitch.
Always leave just enough slack so the
combination can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
Loaded trailers over 450 kg (1,000 lb)
must be equipped with brake systems
and with brakes for each axle. Trailer
braking equipment conforming to
Canadian Standards Association (CSA)
requirement CAN3-D313, or its
equivalent, is recommended.
State or local regulations may require
trailers to have their own braking
system if the loaded weight of the
trailer exceeds certain minimums that
can vary from state to state. Read and
follow the instructions for the trailer
brakes so they are installed, adjusted,
and maintained properly. Never
attempt to tap into your vehicle's
hydraulic brake system. If you do,
both the vehicle anti-lock brakes and
the trailer brakes may not function,
which could result in a crash.
Trailer Lamps
Always check all trailer lamps are
working at the beginning of each trip,
and periodically on longer trips.

Turn Signals When Towing a
Trailer
When properly connected, the trailer
turn signals will illuminate to indicate
the vehicle is turning, changing lanes,
or stopping. When towing a trailer,
the arrows on the instrument cluster
will illuminate even if the trailer is not
properly connected or the bulbs are
burned out.

(Continued)
Warning (Continued)
may interfere with vehicle systems.
This could affect vehicle operation
and cause a crash. Such devices
may also access information stored
in the vehicle’s systems.
Caution
Some electrical equipment can
damage the vehicle or cause
components to not work and would
not be covered by the vehicle
warranty. Always check with your
dealer before adding electrical
equipment.
Add-on equipment can drain the
vehicle's 12-volt battery, even if the
vehicle is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see Servicing
the Airbag-Equipped Vehicle 058 and
Adding Equipment to the
Airbag-Equipped Vehicle 058.

VEHICLE CARE 397
If equipped, carefully open the cover
by using the small notch that conceals
the rear tow eye socket. Install the
tow eye into the socket and turn it
until it is fully tightened. When the
tow eye is removed, reinstall the cover
with the notch in the original
position.
Recreational Vehicle
Towing
Caution
Dolly towing or dinghy towing the
vehicle may cause damage because
of reduced ground clearance.
Always put the vehicle on a flatbed
truck or trailer.
The vehicle was neither designed nor
intended to be towed with any of its
wheels on the ground. If the vehicle
must be towed, see Towing the Vehicle
(Electronic Shifter) 0393 or
Towing the Vehicle (Mechanical Shifter)
0 395.
Appearance Care
Exterior Care
Locks
Locks are lubricated at the factory.
Use a de-icing agent only when
necessary, and have the locks greased
after using. See Recommended Fluids
and Lubricants 0417.
Washing the Vehicle
To preserve the vehicle finish, wash it
often and out of direct sunlight.
Caution
Do not use petroleum-based, acidic,
or abrasive cleaning agents as they
can damage the vehicle's paint,
metal, or plastic parts. If damage
occurs, it would not be covered by
the vehicle warranty. Approved
cleaning products can be obtained
from your dealer. Follow all
manufacturer directions regarding
correct product usage, necessary
(Continued)
Caution (Continued)
safety precautions, and appropriate
disposal of any vehicle care
product.
Caution
Avoid using high-pressure washes
closer than 30 cm (12 in) to the
surface of the vehicle. Use of power
washers exceeding 8 274 kPa
(1,200 psi) can result in damage or
removal of paint and decals.
Automatic Car Wash
Caution
Automatic car washes can cause
damage to the vehicle, wheels,
ground effects, and convertible top
(if equipped).
Do not use automatic car washes
due to lack of clearance for the
undercarriage, wide rear tires, and
wheels.
