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

162 2-4. Using other driving systems
■VSC OFF mode
Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds.
The TRAC OFF and VSC OFF
indicators will come on.
The system is in TRAC off and
VSC off mode.
■Sounds and vibrations caused by the ABS, TRAC, VSC and brake
assist system
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■Automatic reactivation of TRAC and VSC
Turning the “ENGINE START STOP” or the engine switch OFF after turning
off the TRAC and VSC systems will automatically re-enable them.

When driving
Trailer towing tips
Your vehicle will handle differently when towing a trailer. In order to
avoid accident, death or serious injury, keep the following in mind
when towing:
●Before starting out, check the trailer’s light and the vehicle-trailer
connections. Recheck after driving a short distance.
●Practice turning, stopping and reversing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install the
trailer hitch on the bumper; this may cause body damage.
■Brakes
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
■Safety chain
A safety chain must always be used between the towing vehicle and the
trailer. Leave sufficient slack in the chain for turns. The chain should cross
under the trailer tongue to prevent the tongue from dropping to the ground in
the case that it becomes damaged or separated. For the correct safety chain
installation procedure, ask your Toyota dealer.
■Do not directly splice trailer lights
Directly splicing may damage your vehicle’s electrical system and cause a
malfunction.

178 2-5. Driving information
●Reversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right to
move the trailer to the right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
●As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least one vehicle and trailer length.
●Avoid sudden braking as you may skid, resulting in jackknifing and
loss of control. This is especially true on wet or slippery surfaces.
●Avoid jerky starts or sudden acceleration. Vehicles with a manual
transmission, prevent excessive clutch slippage by keeping engine
rpm low and not racing the engine. Always start out in first gear.
●Avoid jerky steering and sharp turns, and slow down before mak-
ing a turn.
●Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
●Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway. Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the steering or brakes, your vehicle and
trailer will stabilize.
●Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you have plenty of room before changing
lanes.

When driving
●In order to maintain engine braking efficiency, do not use the trans-
mission in D (automatic transmission) or 5 (manual transmission).
●Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
(P. 345)
●Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P (automatic transmission) or in 1 or R (manual
transmission). Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle and
trailer wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into 1 or R (manual transmission) or P (automatic trans-
mission) and turn off the engine.
●When restarting after parking on a slope:
With the transmission in P (automatic transmission) or the
clutch pedal (manual transmission) depressed, start the
engine. On vehicles with an automatic transmission, be sure
to keep the brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake (also brake pedal on vehicles with
an automatic transmission), and slowly pull or back away from
the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

CAUTION
■When raising your vehicle
Make sure to observe the following to reduce the possibility of death or seri-
ous injury.
●When using a floor jack, follow the instructions of the manual provided with
the jack.
●Do not use the jack that was supplied with your vehicle.
●Do not put any part of your body or get underneath the vehicle supported
only by the floor jack.
●Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
●Do not start the engine while the vehicle is supported by the floor jack.
●Stop the vehicle on level firm ground, firmly set the parking brake and put
the shift lever in P (automatic transmission) or R (manual transmission).
●Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
●Do not raise the vehicle while someone is in the vehicle.
●When raising the vehicle, do not place any objects on top of or underneath
the floor jack.
●Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

5-1. Essential information
Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Turn the engine switch to the ACC or LOCK position.
Restart the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine.
To minimize the risk of fuel leakage when the engine stalls or an air-
bag inflates upon collision, the fuel pump shut off system stops sup-
plying fuel to the engine.
