2004-2. Driving procedures
4RUNNER (U)_(OM35B37U)
CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the
steering lock in this circumstance may lead to an accident, resulting in
death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 2 seconds, or press it briefly
3 times or more in succession. ( →P. 407)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop
the vehicle as soon as it is safe to do so.
NOTICE
■ To prevent battery discharge
Do not leave the engine switch in ACCESSORY or IGNITION ON mode for
long periods of time without the engine running.
■ When starting the engine
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your Toyota dealer immediately.
