88 SAFETY
Electronic Q2 System (E-Q2)
The Electronic Q2 system intervenes during accelera-
tion on corners, braking the inner drive wheel and thus
increasing the traction of the outer wheel (which bears
more of the vehicles weight): the torque is thus distrib-
uted optimally between the drive wheels in accordance
with the driving conditions and road surface, permit-
ting particularly effective, sporty driving.
Ready Alert Brake System (RAB)
This function activates automatically if the accelerator
pedal is released rapidly, reducing the brake pad travel
(both at front and back), with the aim of preparing the
braking system and enhancing its responsiveness, thus
reducing the stopping distance in the event of subse-
quent braking.

AUXILIARY DRIVING SYSTEMS

Tire Pressure Monitoring System (TPMS)

The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold tire pressure.
The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mile
(1.6 km) after a three hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall. Refer to "Tires" in
"Servicing And Maintenance" for information on how
to properly inflate the vehicle's tires. The tire pressure
will also increase as the vehicle is driven - this is normal
and there should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low pressure warning
limit for any reason, including low temperature effects,
or natural pressure loss through the tire.
