CAUTION
■If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning light
not come on when you start the engine, this could mean that these systems
are not available to help protect you in an accident, which could result in
death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.
■ Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. ( P. 436)
*: These lights turn on when the engine switch is turned to the ON
position to indicate that a system check is being performed. They will
turn off after the engine is started, or after a few seconds. There may
be a malfunction in a system if a light does not come on, or if the
lights do not turn off. Have the vehicle inspected by your Toyota
dealer.

When driving
Gently depress the accelerator pedal.
Unlock the rear differential as soon as the vehicle moves out.
To unlock the rear differential, push the switch again.
■Locking the rear differential
●When the rear differential is locked, VSC is automatically turned off.
(The rear differential lock and VSC OFF indicators come on.)
● The following systems do not operate when the rear differential is locked.
It is normal operation for the ABS warning light, VSC OFF indicator and
slip indicator to be on at this time.
•ABS
• Brake assist system
•VSC
•TRAC
■ The rear differential lock is disengaged when
●Turn the four-wheel drive control switch to the H2 or H4 position.
Never forget to turn off the switch after using this feature.
■ After unlocking the rear differential
Check that the indicator goes off.
CAUTION
■To avoid an accident
●Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or ragged surface. Large steering effort
and careful cornering control will be required.
● Do not lock the rear differential until the wheels have stopped spinning.
Otherwise, the vehicle may move in an unexpected direction when the dif-
ferential lock is engaged, resulting in an accident. This may also lead to
possible damage to rear differential lock component parts.
● Do not drive over 5 mph (8 km/h) when the rear differential is locked.
● Do not keep driving with the RR DIFF LOCK switch on.

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.
■ABS (Anti-lock Brake System)
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
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)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control)
Maintains drive power and prevents the rear wheels (2WD models and
H2 mode on Multi-mode 4WD models) or all wheels (4WD models
except on L4 mode) from spinning when starting the vehicle or acceler-
ating on slippery roads.
■A-TRAC (Active Traction Contro l) for L4 mode on 4WD mod-
els (vehicles with the A-TRAC switch except when the cen-
ter differential lock is locked)
Maintains drive power and prevents the all wheels from spinning when
starting the vehicle or accelerating on slippery roads.
■ Hill-start assist control (if equipped)
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operates for approximately 5 seconds at
maximum.

196 2-4. Using other driving systems
■Sounds and vibrations caused by the ABS, TRAC, A-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.
■ If the brake system overheats
TRAC will cease operation and a buzzer will sound to alert the driver. Stop
the vehicle in a safe place. (There is no problem with continuing normal driv-
ing.)

2-4. Using other
driving systems

When driving
CAUTION
■The ABS does not opera te effectively when
● The limits of the gripping performance have been exceeded.
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating will exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with pothol es or roads with uneven roads
■ When VSC is activated
The slip indicator flashes and a warning buzzer sounds. Always drive care-
fully. Reckless driving may cause an accident. Exercise particular care when
the indicator flashes and a buzzer sounds.
■ TRAC/A-TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if TRAC/A-TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS and VSC will not function correctly if different tires are fitted on the
vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

When driving
●
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. 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 pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
● When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep
the brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
■ Service connector for towing brake controller (if equipped)
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.

268 3-2. Using the audio system
■Setting the rear seat entertainment system lock (if equipped)
When RSE is selected, turn
until ON/OFF is displayed.
The rear seat entertainment sys-
tem lock remains on, even when
the engine switch is turned off.

382 4-3. Do-it-yourself maintenance
■Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Turn the engine switch off.
Depress the brake pedal 20 times or more.
Remove the reservoir cap.
Add newly opened brake fluid up to the MAX line.
.
Fluid type FMVSS No.116 DOT 3 or SAE J1703 brake fluid
ItemsRag or paper towel
■ Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or 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 or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.
■ If you spill fluid
Be sure to wash it off with water to prevent damage to parts or paint.
