Tyre Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated
tyre to the recommended cold tyre
pressure.
When the low tyre pressure warning
light comes on:
1. Park the vehicle in a safe, level
place.
2. Apply the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tyre that is
underinflated. The indicator lamp
will flash.
When the recommended pressure
is reached, the horn sounds once
and the indicator lamp will stop
flashing and briefly turn solid.
Repeat these steps for all
underinflated tyres that have
illuminated the low tyre pressure
warning light.

Warning
Overinf lating a tyre could cause the
tyre to rupture and you or others
could be injured. Do not exceed the
maximum pressure listed on the
tyre sidewall.
If the tyre is overinflated by more
than 35 kPa (5 psi), the horn will
sound multiple times and the
indicator lamp will continue to flash
for several seconds after filling stops.
To release and correct the pressure,
while the indicator lamp is still
flashing, briefly press the centre of the
valve stem. When the recommended
pressure is reached, the horn
sounds once.
If the indicator lamp does not flash
within 15 seconds after starting to
inflate the tyre, the tyre fill alert has
not been activated or is not working.
If the hazard warning flashers are on,
the tyre fill alert visual feedback will
not work properly.
The TPMS will not activate the tyre
fill alert properly under the following
conditions:
.
There is interference from an
external device or transmitter.
.
The air pressure from the inflation
device is not sufficient to inflate
the tyre.
.
There is a malfunction in the TPMS.
.
There is a malfunction in the horn
or indicator lamps.
.
The identification code of the TPMS
sensor is not registered to the
system.
.
The batter y of the TPMS sensor
is low.
If the tyre fill alert does not operate
due to TPMS interference, move the
vehicle about 1 m (3 ft) back or
forward and tr y again. If the tyre fill
alert feature is not working, use a tyre
pressure gauge.
TPMS Sensor Matching Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tyre/wheel position after rotating the
vehicle's tyres or replacing one or
more of the TPMS sensors. The TPMS
sensor matching process should also
be performed after replacing a spare
