Spare tire (TEMPORARY USE
ONLY spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be dam-
aged or involved in an accident:
WARNING
∙ The spare tire should be used for emer-gency use only. It should be replaced with
the standard tire at the first opportunity
to avoid possible tire or differential
damage.
∙ Drive carefully while the TEMPORARY USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
∙ Periodically check spare tire inflation pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 420 kPa, 4.2 bar (60 psi).
∙ With the TEMPORARY USE ONLY spare tire installed do not drive the vehicle at
speeds faster than 50 mph (80 km/h). ∙ When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on the
rear wheels and the original tire used on
the front wheels (drive wheels).
∙ Tire tread of the TEMPORARY USE ONLY spare tire will wear at a faster rate
than the standard tire. Replace the spare
tire as soon as the tread wear indicators
appear.
∙ Do not use the spare tire on other vehicles.
∙ Do not use more than one spare tire at the same time.
∙ Do not tow a trailer when the TEMPO- RARY USE ONLY spare tire is installed.
CAUTION
∙ Do not use tire chains on a TEMPORARYUSE ONLY spare tire. Tire chains will not
fit properly and may cause damage to the
vehicle.
∙ Because the TEMPORARY USE ONLY spare tire is smaller than the original tire,
ground clearance is reduced. To avoid
damage to the vehicle, do not drive over
obstacles. Also, do not drive the vehicle
through an automatic car wash since it
may get caught.

∙ Choose the proper class hitch ball basedon the trailer weight.
∙ The diameter of the threaded shank of the hitch ball must be matched to the ball
mount hole diameter. The hitch ball shank
should be no more than 1/16” smaller
than the hole in the ball mount.
∙ The threaded shank of the hitch ball must be long enough to be properly secured to
the ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Ball mount
The hitch ball is attached to the ball mount
and the ball mount is inserted into the hitch
receiver. Choose a proper class ball mount
based on the trailer weight. Additionally, the
ball mount should be chosen to keep the
trailer tongue level with the ground.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and gross
weight directly on the ball mount and on the
receiver.
Weight distribution hitch
This type of hitch is also called a “load-leveling”
or “equalizing” hitch. A set of bars attach to the
ball mount and to the trailer to distribute the
tongue weight (hitch weight) of your trailer.
Many vehicles can’t carry the full tongue
weight of a given trailer, and need some of the
tongue weight transferred through the frame
and pushing down on the front wheels. This
gives stability to the tow vehicle.
A weight-distributing hitch system (Class IV)
is recommended if you plan to tow trailers
with a maximum weight over 5,000 lbs.
(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may af-
fect the operation of trailer surge brakes. If
you are considering use of a weight-
distributing hitch system with a surge
brake-equipped trailer, check with the surge
brake, hitch or trailer manufacturer to de-
termine if and how this can be done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system. General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface. With the ignition on and the doors
closed, allow the vehicle to stand for
several minutes so that it can level.
2. Measure the height of a reference point on the front and rear bumpers at the
center of the vehicle.
3. Attach the trailer to the vehicle and ad- just the hitch equalizers so that the front
bumper height is within0-.5inches (0 –
13 mm) of the reference height mea-
sured in step 2. The rear bumper should
be no higher than the reference height
measured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no higher
than the measured reference height when
the trailer is attached. If the rear bumper is
higher than the measured reference height
when loaded, the vehicle may handle unpre-
dictably which could cause a loss of vehicle
control and cause serious personal injury or
property damage.
