Starting and stopping the
engine
& General precautions when
starting/stopping engine
WARNING
. Never start the engine from out-
side the vehicle. It may result in
an accident.
. Do not start the engine near dry
foliage, paper, or other flam-
mable substances. The exhaust
pipe and exhaust emissions can
create a fire hazard at high
temperatures.
. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
CAUTION
. Do not stop the engine while
driving. Otherwise, the catalyst
may overheat and burn.
. When starting the engine, be sure
7-9
to sit in the driver’s seat (except
when using the remote engine
start system).
NOTE
. Avoid rapid acceleration immedi-
ately after the engine has started. In
addition, always avoid rapid racing.
. Until the engine is warmed up
sufficiently, the engine speed is main-
tained high. The engine speed will
gradually drop as the engine warms up.
. On rare occasions, it may be difficult
to start the engine depending on the
fuel used and the driving condition
(repeated short trips when the engine
is not warmed up sufficiently). In such
cases, it is recommended to switch to a
different brand of fuel.
. On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly
such as a rapid start-up and a rapid
acceleration. This is not a malfunction.
. The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.
. It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically
