When the hill‑start assist system stops
braking the vehicle, it can roll
backwards.
If you open the driver’s door, the
hill‑start assist system is deactivated
and a warning signal sounds.
Your vehicle has a hill‑start assist system.
On uphill grades the hill‑start assist
system maintains the pressure in the brake
system for approximately one second after
you have released the brake pedal.
Therefore, you can start off smoothly
without the vehicle moving immediately
after releasing the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the
accelerator pedal to drive off.
On uphill grades with higher inclination,
the hill-start assist system will release
the pressure in the brake system after
approximately two seconds. A warning
signal sounds and the transmission
position indicator shows a flashing N in
order to warn you of the vehicle rolling
backwards.
X Press the brake pedal.
X Release the brake pedal.

responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination
of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately 1 minute and then remain
continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement
or alternate tires and wheels allow the
TPMS to continue to function properly.
i If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i Operating radio transmission
equipment (e.g. wireless headsets, two-
way radios) in or near the vehicle could
cause the TPMS to malfunction. i

Restarting the TPMS G
WARNING
It is the driver’s responsibility to
calibrate the TPMS on the recommended
cold inflation pressure. Underinflated
tires affect the ability to steer or brake
and might cause you to lose control of the
vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a
new level (e.g. because of differen tload or
driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures. 126
