4-1. Before driving
WARNING
●Do not touch the exhaust pipes while the engine is running or
immediately after turning the engine off.Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise,
if you accidentally move the shift lever or depress the accelerator pedal, this could cause an accident or fire due to
engine overheating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust gases may collect and
enter the vehicle, leading to death or a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of the vehicle to
brake differently than the other side. Also, the parking brake may not securely hold the vehicle.
●If the brake booster device does not operate, do not follow other vehi-
cles closely and avoid hills or sharp turns that require braking.In this case, braking is still possible,
but the brake pedal should be depressed more firmly than usual. Also, the braking distance will
increase. Have your brakes fixed immediately.
●Do not pump the brake pedal if the engine stalls.Each push on the brake pedal uses
up the reserve for the power- assisted brakes.
●The brake system consists of 2 indi-vidual hydraulic systems; if one of the systems fails, the other will still
operate. In this case, the brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when a driven wheel is up in the air,
or the vehicle is stuck in sand, mud, etc. This may damage the driveline components or propel the vehicle for-
ward or backward, causing an acci- dent.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, as this may restrain
the engine output.
●Do not shift gears unless the clutch
pedal is fully depressed. After shift- ing, do not release the clutch pedal abruptly. Doing so may damage the
clutch, transmission and gears.
●Observe the following precautions.
Failure to do so may cause exces- sive premature wear or damage to the clutch, eventually making it diffi-
cult to accelerate and start off from a stop. Have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
• Do not rest your foot on the clutch pedal or depress it any time other than when shifting.
Doing so may cause clutch trouble.
• Do not use any gear other than the
1st gear when starting off and mov- ing forward.Doing so may damage the clutch.
