128 2-1. Driving procedures
NOTICE
nWhen driving the vehicle
Vehicles with a manual transmission
l Do not depress the accelerator and brake pedals at the same time during
driving. If the brake pedal is depressed while driving with the accelerator
pedal depressed, driving torque may be restrained.
l Do not rest your foot on the clutch pedal while driving.
Doing so may cause clutch trouble.
l Do not use any gears other than the first gear when starting off and mov-
ing forward.
Doing so may damage the clutch.
l Do not use the clutch to hold the vehicle when stopping on an uphill grade.
Doing so may damage the clutch.
Vehicles with an automatic transmission
l Do not depress the accelerator and brake pedals at the same time during
driving. If the brake pedal is depressed while driving with the accelerator
pedal depressed, driving torque may be restrained.
l Do not use the accelerator pedal or depress accelerator and brake pedals
together to hold the vehicle on a hill.
n When parking the vehicle
Vehicles with an automatic transmission: Always put the shift lever in P.
Failure to do so may cause the vehicle to move or the vehicle may acceler-
ate suddenly if the accelerator pedal is accidentally depressed.
n Avoiding damage to vehicle parts
lDo not turn the steering wheel fully in either direction and hold it there for a
long time.
Doing so may damage the power steering motor.
l When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
nABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
nBrake Assist (if equipped)
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
nVSC (Vehicle Stability Control) (if equipped)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
nTRAC (Traction Control) (if equipped)
Maintains drive power and prevents the front wheels from spinning
when starting the vehicle or accelerating on slippery roads.
nEPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

310 5-1. Essential information
nEmergency towin g procedure
Release the parking brake.
Put the transmission in N.
Turn the engine switch to the ACC (engine off) or ON (engine run-
ning) position.
CAUTION
n Caution while towing
lUse extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelet and the cables or chains. Always
use caution for the surroundings and other vehicles while towing.
l If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.
NOTICE
nTo prevent causing serious dama ge to the transmission
(vehicles with an automatic transmission)
Never tow this vehicle from the rear with the front wheels on the ground.
This may cause serious damage to the transmission.
n When towing a vehicle without using a towing dolly
(vehicles with a manual transmission)
Do not tow with the key removed or in the LOCK position.

nCustomization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled. (Cus-
tomizable features → P. 383)
CAUTION
nWhen the electric power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, firmly
hold and operate it using more force than usual.
n
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and re sult in death or serious injury.
lStop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
lIf the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota dealer.
lAvoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
nIf a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.
nMaintenance of the tire
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr essure for those tires.)

5-2. Steps to take in an emergency
CAUTION
n
If the engine has to be turned off while driving
lPower assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
l Never attempt to remove the key, as doing so will lock the steering wheel.
