is reset, change the engine oil every year.
# : See information on maintenance and emissions warranty in the first column on page 581.
*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).

*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission
temperatures. This requires transmission fluid changes more frequently than recommended by the
Maintenance Minder
TM. If you regularly drive your vehicle under these conditions, have the transmission
fluid changed at every 30,000 miles (48,000 km) or 2 years.
*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under
-20°F, -29°C), or towing a trailer, replace every 60,000 miles (U.S.) / 100,000 km (Canada).
*6: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than
recommended by the Maintenance Minder
TM. If you regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

uuChecking and Maintaining Tires uTire and Wheel Replacement
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.
Whenever you have a tire replaced or reset, make sure that the rubber valve stem is
replaced and that the TPMS sensor is trans ferred from the old valve stem to the new
one.
If you replace a wheel, make sure that the wheel’s specifications match those of the
original wheels.
1 Tire and Wheel Replacement
3WARNING
Installing improper tires on your vehicle can
affect handling and stability. This can cause
a crash in which you can be seriously hurt or
killed.
Always use the size and type of tires
recommended in this owner’s manual.

uuEngine Does Not Start uEmergency Engine Stop
Handling the Unexpected
Emergency Engine Stop
The ENGINE START/STOP button may be used to stop the engine due to an
emergency situation even while driving. If you must stop the engine, do either of the
following operations:
• Press and hold the ENGINE START/STOP button for about two seconds.
• Firmly press the ENGINE START/STOP button three times.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort an d time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The transmission automa tically changes to
(P after the vehicle comes to a complete
stop.
Then, the power mode changes to VEHICLE OFF.
Then press the ENGINE START/STOP button twice without depressing the brake
pedal to change the mode to VEHICLE OFF.
1 Emergency Engine Stop
Do not press the ENGINE START/STOP button while
driving unless it is absolute ly necessary for the engine
to be turned off.
If you press the ENGINE START/STOP button while
driving, the beeper sounds.

■What to do when the indicator comes on while driving
Depress the brake pedal lightly to check pedal pressure.
• If normal, check the brake fluid level the next time you stop.
• If abnormal, take immediate acti on. If necessary, downshift the
transmission to slow the vehicle using engine braking.
If the Electric Power Steeri ng (EPS) System Indicator
Comes On
■Reasons for the indicator to come on
Comes on when there is a pr oblem with the EPS system.
■What to do when the indicator comes on
Stop the vehicle in a safe place and restart the engine.
If the indicator comes on and stays on, immediately have your vehicle

the gears.

come on simultaneously , the electronic brake
distribution system is not wo rking. This can result in
vehicle instability under sudden braking.
