Compact Spare Tire
{Warning
Driving with more than one compact
spare tire at a time could result in loss of
braking and handling. This could lead to a
crash and you or others could be injured.
Use only one compact spare tire at
a time.
If this vehicle has a compact spare tire, it
was fully inflated when new; however, it
can lose air over time. Check the inflation
pressure regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check that the
spare tire is correctly inflated after being
installed on the vehicle. The compact spare
tire is designed for temporary use only. The
vehicle will perform differently with the
spare tire installed and it is recommended
that the vehicle speed be limited to 80 km/h
(50 mph). To conserve the tread of the spare
tire, have the standard tire repaired or
replaced as soon as convenient and return
the spare tire to the storage area.

14430430) - 2021 - CRC - 9/9/20
Vehicle Care 293
When using a compact spare tire, the AWD
(if equipped), ABS, and Traction Control
systems may engage until the spare tire is
recognized by the vehicle, especially on
slippery roads. Adjust driving to reduce
possible wheel slip.
Caution
When the compact spare is installed, do
not take the vehicle through an
automatic car wash with guide rails. The
compact spare can get caught on the rails
which can damage the tire, wheel, and
other parts of the vehicle.
Do not use the compact spare on other
vehicles.
Do not mix the compact spare tire or wheel
with other wheels or tires. They will not fit.
Keep the spare tire and its wheel together.
Caution
Tire chains will not fit the compact spare.
Using them can damage the vehicle and
the chains. Do not use tire chains on the
compact spare.
Full-Size Spare Tire
If this vehicle came with a full-size spare
tire, it was fully inflated when new,
however, it can lose air over time. Check the
inflation pressure regularly. See Tire Pressure
0 272 and
Vehicle Load Limits 0180 for information
regarding proper tire inflation and loading
the vehicle. For instructions on how to
remove, install, or store a spare tire, see Tire
Changing 0284.
If equipped with a temporary use full-size
spare tire, it is indicated on the tire sidewall.
See Tire Sidewall Labeling 0267. This spare
tire should not be driven on over 112 km/h
(70 mph), or 88 km/h (55 mph) when
pulling a trailer, at the proper inflation
pressure. Repair and replace the road tire as
soon as it is convenient, and stow the spare
tire for future use.
Caution
If the vehicle has four-wheel drive and a
different size spare tire is installed, do
not drive in four-wheel drive until the flat
tire is repaired and/or replaced. The
vehicle could be damaged and the repairs
(Continued)
Caution (Continued)
would not be covered by the warranty.
Never use four-wheel drive when a
different size spare tire is installed on the
vehicle.
The vehicle may have a different size spare
tire than the road tires originally installed
on the vehicle. This spare tire was developed
for use on this vehicle, so it is all right to
drive on it. If the vehicle has four-wheel
drive and a different size spare tire is
installed, drive only in two-wheel drive.
After installing the spare tire on the vehicle,
stop as soon as possible and check that the
spare is correctly inflated. The spare tire is
made to perform well at speeds up to
112 km/h (70 MPH) at the recommended
inflation pressure, so you can finish
your trip.
Have the damaged or flat road tire repaired
or replaced and installed back onto the
vehicle as soon as possible so the spare tire
will be available in case it is needed again.
Do not mix tires and wheels of difference
sizes, because they will not fit. Keep the
spare tire and its wheel together.

Recreational Vehicle Towing
Recreational vehicle towing means towing
the vehicle behind another vehicle, such as a
motor home. The two most common types
of 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.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.
Follow the tow vehicle manufacturer’s
instructions.
