▼Gate operator/Canadian
Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or
quit) after several seconds of
transmission ― which may not be long
enough for HomeLink
to pick up the
signal during programming. Similar to
this Canadian law, some U.S. gate
operators are designed to “time-out”
in the same manner.

If you live in Canada or are having
di fficulties programming a gate
operator by using the programming
procedures (regardless of where you
live), replace Step 3 of Programming
the HomeLink System with the
following:
NOTE
If programming a garage door opener
or gate operator, it is advised to unplug
the device during the “cycling” process
to prevent possible overheating.
While the indicator light is flashing in
amber, press the button on the
hand-held transmitter for 2 seconds
and release it repeatedly until the
indicator light changes from amber to
green.
Go back to Step 4 of Programming the
HomeLink System to complete the
procedure.
▼ Operating the HomeLink System
Press the programmed HomeLink
button to operate a programmed
device.

HomeLink button. DO NOT release
the button.
2. After 20 seconds, the indicator light
fl ashes in amber. After the indicator
light flashes, release the HomeLink
button.
3. Go back to Step 2 of Programming the HomeLink System to complete
the procedure.
NOTE
If the programming has not been
completed, the system returns to the
previous programming.

The garage door two-way
communication is a function that
communicates with the garage door
opener and indicates whether the
garages door is open or closed using
the indicator lights in the rear view
mirror. It can indicate the status of the
garage door within a range up-to 250
m (820 ft).
NOTE
The communication range may shorten
depending on obstructions.
Programming two-way
communication
Within
five seconds after programming
a new HomeLink button, both of the
garage door status indicator lights will

Brake System
▼Foot Brake
This vehicle has power-assisted brakes
that adjust automatically through
normal use.

Should power-assist fail, you can stop
by applying greater force than normal
to the brake pedal. But the distance
required to stop will be greater than
usual.
WARNING
Do not coast with the engine stalled
or turned o
ff, fi nd a safe place to stop:
Coasting with the engine stalled or
turned o ff is dangerous. Braking will
require more e ffort, and the brake's
power-assist could be depleted if you
pump the brake. This will cause longer
stopping distances or even an
accident.
Shift to a lower gear when going
down steep hills:
Driving with your foot continuously on
the brake pedal or steadily applying
the brakes for long distances is
dangerous. This causes overheated
brakes, resulting in longer stopping
distances or even total brake failure.
This could cause loss of vehicle control
and a serious accident. Avoid
continuous application of the brakes.
Dry o ff brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
a ff ected.
CAUTION
 Do not drive with your foot held on
the clutch pedal or brake pedal, or
hold the clutch pedal depressed
halfway unnecessarily. Doing so
could result in the following:
 The clutch and brake parts will
wear out more quickly.
 The brakes can overheat and
adversely
aff ect brake
performance.
 Always depress the brake pedal with
the right foot. Applying the brakes
with the unaccustomed left foot
could slow your reaction time to an
emergency situation resulting in
insu fficient braking operation.
 Wear shoes appropriate for driving in
order to avoid your shoe contacting
the brake pedal when depressing the
accelerator pedal.

▼Electric Parking Brake (EPB)
The EPB system applies the parking
brake using an electric motor. The
system can operate automatically and
manually.
The EPB switch indicator light turns on
when applying the parking brake and it
turns off
when releasing the parking
brake.
1. Indicator light
WARNING
Do not drive the vehicle with the
parking brake applied:
If the vehicle is driven with the parking
brake applied, the brake parts may
generate heat and the brake system
may not operate, leading to an
accident.
Before driving the vehicle, release the
parking brake and make sure that the
EPB indicator light in the instrument
cluster turns off.
Apply the parking brake when leaving
the vehicle:
Not applying the parking brake when
parking the vehicle is dangerous as the
vehicle may move unexpectedly and
result in an accident. Before leaving the
vehicle, apply the parking brake and
make sure that the EPB indicator light
in the instrument cluster turns on.
NOTE
The parking brake cannot be applied
or released while the vehicle battery
is dead.
Refer to If a Jump-Starting on page
7-17.
When the charging system warning
light in the instrument cluster turns
on, the parking brake cannot be
applied after switching the ignition
OFF. Before switching the ignition
OFF, apply the parking brake
manually.
The sound of the parking brake being
applied or released can be heard,
however, this does not indicate a
problem.
If the EPB is not used for long
periods, an automatic inspection of
the system is performed while the
vehicle is parked. An operation
sound can be heard, however, this
does not indicate a problem.
When applying the parking brake
and switching OFF the ignition, an
operation sound can be heard,
however, this does not indicate a
problem.
The brake pedal may move while
applying or releasing the parking
brake, however, this does not
indicate a problem.
