Driving
Always confirm the electric parking brake is se t, in particular if you are parked on an
incline.1 When Stopped
In extremely cold temper atures, the parking brake
may freeze up if applied. If such temperatures are
expected, do not apply the parking brake but, if
parking on a slope, either turn the front wheels so
they will contact the curb if the vehicle rolls down the
slope or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the
vehicle may roll unexpect edly, leading to a crash.

Driving
7. Place the fuel fill cap in the holder.
8. Insert the fuel filler nozzle fully.
u When the tank is full, the filler nozzle will
click off automatically. This leaves space
in the fuel tank in case the fuel expands
with a change in the temperature.
9. After filling, replace the fuel fill cap,
tightening it until you hear it click at least
once.
u Shut the fuel fill door by hand.1How to Refuel
If the fuel fill door does not open after you press the
button, even after the display changes to Ready, you
can manually open the door. 2 When You Cannot Unlock the Fuel Fill Door
P. 566
An internal valve automatically closes after 30
minutes from the moment y ou press the fuel fill door
release button. When it does, do not continue to
refuel as fuel may spill out.
When the fuel fill door auto matically opens, a vent
valve in the fuel system also opens to allow the air
and the vapors being displace d by the fuel to escape.
This valve automatically closes, however, if the
refueling is not completed within 30 minutes. If this
happens, reinstall the fuel ca p, close the fuel fill door,
and then follow these steps again to restart the
system.
