Handling the Unexpected
If a Tire Goes Flat
Changing a Flat Tire
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe plac e. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possib le to have the full-size tire repaired or
replaced.
1. Park the vehicle on a firm, level, non-slippery surface and apply the parking brake.
2. Put the transmission into
(P.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF.
1Changing a Flat Tire
Follow compact spare precautions:
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model. Do not use them with
another vehicle. Do not us e another type of compact
spare tire or wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairi ng agent on a flat tire,
as it can damage the tire pressure sensor.

Handling the Unexpected
If you replace a flat tire with the comp act spare tire, the low tire pressure/TPMS
indicator comes on while you are driving. A fter driving for a few miles (kilometers),
Tire Pressure Monitor Problem will appear on the multi-information display and
the indicator will start blinki ng for a short time and then stay on; however, this is
normal and is no cause for concern.
If you replace the tire with a full-size tire, the warning message on the multi-
information display and the low tire pressu re/TPMS indicator will go off after a few
miles (kilometers).
■TPMS with Tire Fill Assist and the Compact Spare Tire1 TPMS with Tire Fill Assist and the Compact Spare Tire
The system cannot monitor the pressure of the
compact spare tire. Manually check the compact
spare tire pressure to be sure that it is correct.
Use the TPMS specific wheels. Each is equipped with
a tire pressure sensor mount ed inside the tire behind
the valve stem.
