Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure ra ting (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist
TM (VSA ®) system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
If you replace a wheel, only use TPMS sp ecified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.

Maintenance
Winter Tires
If driving on snowy or frozen roads, mount all season marked M+S tires, snow tires,
or tire chains; reduce speed; and maintain su fficient distance between vehicles when
driving.
Be particularly careful when operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all season ti res when necessary or according to the law.
When mounting, refer to the following points.
For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire cl earance, we strongly recommend using the
chains listed below:
• Follow the chain manufacturer’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not to uch the brake lines or suspension.
• Drive slowly.

2. Change the gear position to
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF
(LOCK).
Vehicles with a compact spare tire
1 Changing 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 the Low Tire Pressure/ TPMS Indicator Comes On or
Blinks
■Reasons for the indicator to come on or blink
A tire pressure is significantly low. If there is a problem with the TPMS
with Tire Fill Assist or the compact spare tire
* is installed, the indicator
blinks for about one minu te, and then stays on.
■What to do when the indicator comes on
Drive carefully and avoid abrupt cornering and hard braking.
Stop your vehicle in a safe place. Ch eck the tire pressure and adjust the
pressure to the specified level. The sp ecified tire pressure is on a label on
the driver side doorjamb.
■What to do when the indicator blinks
Have the tire inspected by a dealer as soon as possible. If the compact
spare tire
* causes the indicator to blink, ch ange the tire to a full-size tire.
The indicator goes off after driving for a few miles (kilometers).
1 If the Low Tire Pressure/TPMS Indicator Comes On or Blinks
NOTICE
Driving on an extremely underinflated tire can cause
it to overheat. An overheated tire can fail. Always
inflate your tires to the prescribed level.
TPMS Fill Assist provides visual and audible assistance
during tire pressure adjustment. With the power
mode in ON, while you adjust tire pressure up or
down, the system alerts you as follows:
Below recommended pressure: The beeper
sounds and exterior lights flash once every five
seconds.
At recommended pressure: The beeper sounds
and exterior lights flash ra pidly for ~ five seconds.
Above recommended pressure: The beeper
sounds and lights flash twice every three seconds.
