2-1. Driving procedures
CAUTION
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine. 
If the vehicle is in any gear other than “P” or “N” the vehicle may accelerate sud-
denly and unexpectedly, and may cause an accident.
●Do not leave the vehicle with the engine on for a long time. 
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do no t enter the vehicle interior.
●Always keep a foot on the brake pedal while the engine is running to prevent an
accident caused by the vehicle moving.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun. 
Failure to do so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Always apply the parking brake, shift the shift lever to “P”, stop the engine and
lock the vehicle. 
Do not leave the vehicle unattend ed while the engine is running.
●Do not touch the exhaust pipe while the engine is running or immediately after
turning the engine off. 
Doing so may cause burns.
●Do not leave the engine running in an area with snow build up, or where snow is
expected to fall. 
Exhaust gases may enter the vehicle and cause gas poisoning.
