uuParking Your VehicleuWhen Stopped
1When Stopped
In extremely cold temperatures, 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 unexpectedly, leading to a crash.
After shutting off the engine, you may hear certain
noises coming from the vehicle. Here's the lowdown:
•
Noise from Under Vehicle: This noise is caused by
the vacuum pump inside the fuel evaporation
leakage check module (ELCM).
Depending on conditions, the pump will come on
for about 15 minutes about 5 to 10 hours after
engine shutoff. This noise is just normal vehicle
operation and don't indicate a vehicle problem.
