2008 TOYOTA SEQUOIA lock

210 2-4. Using other driving systems
■Shifting between 2WD and 4H
●Reduce your speed to less than 62 mph (100 km/h) and set the front
drive control switch between 2WD and 4H.
When the ambient temperature is 5.0° F (-15°C) or lower, shifting from
2WD to 4H can be performed with the vehicle speed below 43 mph (70
km/h).
● If the 4HI indicator does not go off when you shift from 4H to 2WD, drive
straight ahead while accelerating or decelerating, or drive in reverse.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each
month.
This will assure that the front drive components are lubricated.
■ The center differential lock switch can be operated when
●The front drive control switch is in the 4H or 4L position.
● The vehicle speed is less than 62 mph (100 km/h)
■ Center differential lock system
●When the center differential is locked, the vehicle stability control system
is automatically turned off and the center differential lock and VSC OFF
indicator come on.
● When the front drive control switch is turned to the 2WD position, the
center differential is automatically unlocked.
● If the operation is not completed, the center differential lock indicator
blinks. If the indicator does not go off when unlocking the center differen-
tial, drive straight ahead while accelerating or decelerating, or drive \
in
reverse.
■ If the 4LO indicator, 4HI indicator or the center differential lock indica-
tor blinks
● If the 4LO indicator continues to blink when shifting between 4H and 4L,
stop the vehicle completely, move the shift lever to N and operate the
switch again.
● If the shift lever is moved before the 4LO indicator has turned on/off, a
beep sounds and the transfer position may not successfully change. In
this case, stop the vehicle completely, return the shift lever to N and oper-
ate the switch again.

When driving
●If the engine coolant temperature is too low, transfer mode may not be
able to shift. When the engine is warmer turn the switch again.
If the 4LO indicator, 4HI indicator or the center differential lock indicator con-
tinues to blink even after attempting the above, there may be a malfunction
in the engine, the brake system or the four-wheel drive system. In this case,
you may not be able to shift between 2WD and 4H, 4H and 4L, and the cen-
ter differential lock may not be operable. Have the vehicle inspected by your
Toyota dealer immediately.
CAUTION
■ Shift from 2WD to 4H while driving
Never move the front wheel drive control switch if wheels are slipping.
Stop the slipping or spinning before shifting.
NOTICE
■To prevent damage to the center differential
●For normal driving on dry and hard surface roads, unlock the center differ-
ential.
● Unlock the center differential after the wheels are out of the ditch or off the
loose or bumpy surface.
● Do not push the center differential lock switch when the vehicle is corner-
ing or when its wheels are spinning freely off the ground.

Driving assist systems
When VSC/TRAC are operatingIf the vehicle is in danger of slip-
ping, or if the rear wheels (2WD
models) or all wheels (4WD
models) spin, the indicator
flashes to indicate that VSC/
TRAC have been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
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)
Restrains the vehicle from slipping when driving on slick road surfaces
or in the event of sudden braking.
■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) for 2WD
Maintains drive power and prevents the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■A-TRAC (Active Traction Control) for 4WD
Maintains drive power and prevents the all wheels from spinning when
starting the vehicle or accelerating on slippery roads.

216 2-4. Using other driving systems
To disable VSC or TRAC (4H and 4L mode on 4WD models)If the vehicle gets stuck in fresh snow or mud, VSC or TRAC may
reduce power from the engine to the wheels. You may need to turn
the system off to enable you to rock the vehicle in order to free it.
■ TRAC OFF mode
Press the VSC OFF switch
briefly.
The slip indicator should come
on.
The system is in TRAC of engine
control off and VSC on mode.
This mode can be used when the
transfer mode is 4H mode and
the center differential is unlocked.
Push the switch again to turn the
system back on.
■VSC OFF mode
Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds.
The slip and VSC OFF indicators
should come on.
The system is all off mode.

NOTICE
■
To prevent the water damage
●Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
●Sand and mud that has accumulat ed in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.

CAUTION
■Roof luggage carrier precautions
To use the roof rails as a roof luggag
e carrier, you must fit the roof rails
with two or more genuine Toyota cross rails or their equivalent.
When you load cargo on the roof luggage carrier, observe the following:
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the r oof luggage carrier will make the center of the
vehicle gravity higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehicle cor-
rectly.
●If driving for a long distance, on rough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
●Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.
■ Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and rear-
ward them.
Failure to do so may cause an unexpected accident or severe injury in the
event of emergency braking or a collision.
●Place the cargo so that its weight is
distributed evenly between the front
and rear axles.
●If loading long or wide cargo never
exceed the vehicle overall length or
width.

●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 bloc ks 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 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 D or R (if reversing).
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.
