Check when the engi ne is not running.
1.Look at the side of the reservoir. The fluid
should be between the UPPER LEVEL and
LOWER LEVEL .
2. Add power steering fluid if necessary to the
UPPER LEVEL mark.

level goes below the LOWER LEVEL
frequently, have the system inspected as
soon as possible.

uuChecking and Maintaining Tires uWinter Tires
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 sufficient dist ance 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 clearance, 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.
Cable-type: SCC Super Z-6#SZ 435
1Winter Tires
NOTICETraction devices that are the wrong size or improperly
installed can damage your vehicle’s brake lines,
suspension, body, and wheels. Stop driving if they are
hitting any part of the vehicle.
When tire chains are mounted, follow the chain
manufacturer’s instructio ns regarding vehicle
operational limits.
3WARNING
Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.
Follow all instructions in this owner’s
manual regarding the selection and use of
tire chains.

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 possible to have the full-size tire repaired or
replaced.
1. Park the vehicle on firm, level, and non-slippery ground.
2. Put the shift lever in
P.
3. Set the parking brake.
4. Turn on the hazard warn ing lights and turn the ignition switch to LOCK
0*1.
*1: Models with the keyless access system have an ENGINE START/STOP button
instead of an ig nition switch.
1Changing a Flat Tire
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 use 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-repairing agent on a flat tire,
as it can dama ge the tire pressure sensor.

uuIndicator, Coming On/Blinking uIf the Brake System Indicator (Red) Comes On
Handling the Unexpected
If the Brake System Indicator (Red) Comes On
■Reasons for the indicator to come on
• The brake fluid is low.
• There is a malfunction in the brake system.
■What to do when the indicator comes on while driving
Press the brake pedal lightly to check pedal pressure.
• If normal, check the brake fluid level the next time you stop.
• If abnormal, take immediate action. If necessary, downshift the
transmission to slow the vehicle using engine braking.
If the ECPS Indicator* Comes On
■Reasons for the indicator to come on
• Comes on when there is a problem with ECPS.
• If you depress the accelerator pedal repeatedly to increase the engine
speed while the engine is idling, the indicator comes on, and
sometimes the steering wheel becomes harder to operate.
■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
inspected by a dealer.
1 If the Brake System In dicator (Red) Comes On
Have your vehicle repaired immediately.
It is dangerous to drive with low brake fluid. If there
is no resistance from the brake pedal, stop
immediately in a safe plac e. If necessary downshift
the gears.
If the brake system indica tor and ABS indicator come
on simultaneously, the electronic brake distribution
system is not working. This can result in vehicle
instability under sudden braking.
Have your vehicle inspected by a dealer immediately.U.S.
Canada
1 If the ECPS Indicator* Comes On
NOTICEIf you repeatedly turn the steering wheel at an
extremely low speed, or ho ld the steering wheel on
the full left or right position for a while, the system
heats up. The system goes into a protective mode,
and limits its performance. The steering wheel
becomes harder and harder to operate. Once the
system cools down, ECPS is restored. Repeated
operation under these conditions can eventually
damage the system.
