Driving
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 use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■When parking the vehicle
Always set the parking brake and shift the shift lever to P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire (P. 449)
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, tran-
saxle, transfer (AWD models), rear differential (AWD models), etc.
●Lubricant condition for the propeller shaft (AWD models), bearings and
suspension joints (where possible), and the function of all joints, bearings,
etc.

1924-2. Driving procedures
■Automatic deactivation of shift range selection in the D position (vehi-
cles with paddle shift switches)
Shift range selection in the D position will be deactivated in the following situ-
ations:
●The “+” paddle shift switch is held down for a period of time
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for more than a certain period of time
●<003a004b0048005100030057004b004800030056004b004c004900570003004f00480059004800550003004c005600030056004b004c0049005700480047000300570052000300440003005300520056004c0057004c00520051000300520057004b004800
5500030057004b0044005100030027[
■S mode
●When the shift range is 7 or lower, holding the shift lever toward “+” sets the
shift range to 8.
●To prevent the engine from over-revving, upshifting may automatically
occur.
●To protect the automatic transmission, a function is adopted that automati-
cally selects a higher shift range when the fluid temperature is high.
■Downshift restriction warning buzzer (S mode or paddle shifting)
To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever or paddle shift switches are operated. (A
buzzer will sound twice.)
■When driving with dynamic radar cruise control with full-speed range
activated
Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate because dynamic radar cruise con-
trol with full-speed range will not be canceled.
●<003a004b004c004f0048000300470055004c0059004c0051004a0003004c0051000300270003005200550003003600030050005200470048000f000300470052005a00510056004b004c00490057004c0051004a0003005700520003001a000f0003001900

tion. (

■Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the engine switch is in the
IGNITION ON mode the brake pedal is depressed and the shift release but-
ton is pushed.

4-6. Driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
*
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
*: Tire chains cannot be mounted on vehicles with 18 and 19-inch tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Winter driving tips
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

between the “MAX” and “MIN”
lines on the tank.
“MAX”
“MIN”
■Adding fluid
Make sure to check the fluid type and prepare the necessary item.
■Brake fluid can absorb moisture from the air
Excess moisture in the brake fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.

WARNING
■When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious problem.
