Watch the oil pressure gauge. The
needle should begin to rise 15 seconds
after startup. If it doesn’t, shut down
the vehicle immediately and call your
mechanic.

amber, tell your mechanic.

instrument panel. If it lights up or starts

4.
Allow the oil and air pressure gauges
to reach normal operating range before
driving the vehicle.
5.

about the ±rst 10 minutes after startup.
Then, automatic high-idle begins and

rpm.
Some drivers panic a little when the
engine revs higher. They Fip the engine
rpm switch to bring it down to low
idle. That wrong decision keeps oil and
coolant from circulating fast enough
to cool the engine and can result in
damage.
