Brake Pedal Travel

See your dealer/retailer if the brake pedal does not
return to normal height, or if there is a rapid increase in
pedal travel. This could be a sign that brake service
might be required.

Brake Adjustment

Every time you make a brake stop, the disc brakes
adjust for wear.

Replacing Brake System Parts

The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality brake parts.
When you replace parts of the braking system — for
example, when the brake linings wear down and you
need new ones put in — be sure you get new approved
replacement parts. If you do not, the brakes might not
work properly. For example, if someone puts in brake
linings that are wrong for your vehicle, the balance
between the front and rear brakes can change — for the
worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.

Battery

Your vehicle has a standard 12-volt battery and a
high-voltage hybrid battery.
When it is time for a new standard 12-volt battery, see
your dealer/retailer for one that has the replacement
number shown on the original battery's label.
When it is time for a new high-voltage hybrid battery,
see your dealer/retailer.
If an airbag inflates or the vehicle has been in a crash,
the vehicle's sensing system may command the
automatic hybrid battery disconnect to open. See
Replacing Restraint System Parts After a Crash on
page 1-3 for more information.
Warning: Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
