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.
Multi Terrain 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, or in off-
road conditions (such as rough roads, sand and mud).
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.
Active TRC (Traction Control)
Helps to maintain drive power and prevent the 4 wheels from spinning
when starting the vehicle or accelerating on slippery roads.
Hill-start assist control
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope.
KDSS (Kinetic Dynamic Suspension System) (if equipped)
KDSS helps to ensure ride comfort and handling response by using a
hydraulic control system to control the suspension stabilizer bars in
response to road surface and driving conditions during cornering or off-
road driving.
VGRS (Variable Gear Ratio Steering) (if equipped)
Helps to adjust the wheel turning angle in accordance with the vehicle
speed and steering wheel movement.
Pre-Crash Safety (if equipped)

L/C200_EE (OM60G38E)
CAUTION
Active TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the Active TRC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
If the hill-start assist control does not operate effectively
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered in ice.
When Active TRC and VSC are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As there are systems to help to ensure vehicle stability and driving
force, do not turn off Active TRC and VSC unless necessary.
When the VSC is activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes.
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 speci-
fied tire pressure level.
The Multi Terrain ABS and VSC will not function correctly if different tires are
fitted on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional 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
L/C200_EE (OM60G38E)
CAUTION
Off-road driving precautions
Always observe the following precautions to help minimize the risk of serious
personal injury or damage to your vehicle:
Drive carefully when off the road. Do not take unnecessary risks by driving
in dangerous places.
Do not grip the steering wheel spokes when driving off-road. A bad bump
could jerk the wheel and injure your hands. Keep both hands and espe-
cially your thumbs on the outside of the rim.
Always check your brakes for effectiveness immediately after driving in
sand, mud, water or snow.
After driving through tall grass, mud, rock, sand, rivers, etc., check that
there is no grass, bush, paper, rags, stone, sand, etc. adhering or trapped
on the underbody. Clear off any such matter from the underbody. If the
vehicle is used with these materials trapped or adhering to the underbody,
a breakdown or fire could occur.
When driving off-road or in rugged terrain, do not drive at excessive
speeds, jump, make sharp turns, strike objects, etc. This may cause loss
of control or vehicle rollover causing death or serious injury. You are also
risking expensive damage to your vehicle’s suspension and chassis.

Maintenance and care
L/C200_EE (OM60G38E)
Where to go for service?
In order to maintain your vehicle in the highest possible condition, Toyota
recommends that all repairs and service operations be carried out by autho-
rized Toyota dealers or repairers or other duly qualified and equipped profes-
sionals. For repairs and services covered by your warranty, please visit an
authorized Toyota dealer or repairer, who will use genuine Toyota parts in
repairing any difficulties you may encounter. There can also be advantages
in utilizing authorized Toyota dealers or repairers for non-warranty repairs
and services, as members of the Toyota network will be able to expertly
assist you with any difficulties you may encounter.
Your Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional service department will perform all of the scheduled maintenance
on your vehicle-reliably and economically due to their experience with
Toyota vehicles.
Does your vehicle need repair?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condi-
tioning after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon mon-
oxide leak. Drive with the windows open and have the exhaust system
checked immediately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal
Engine continually runs hot, oil pressure gauge stays low
