In altimeter mode, the approximate altitude is displayed.
The displayed altitude ranges from
−1500 ft. (−500 m) up to
13000 ft. (4000 m).
As the altitude value is converted from the atmospheric
pressure, it can be easily affected by air motion and
temperature, so the indication may vary. The indicated altitude
of a single position may deviate according to the atmospheric
pressure and temperature.
The displayed value is updated every 2 seconds.
RECTIFICATION OF THE ALTITUDE
Rectification is valid only when the correct altitude is known.
While the altitude mode is on the display, push the “
” or “”
button to increase or decrease the altitude by 50 ft. (10 m).
To reset the rectified altitude, push and hold the “RESET”
button for more than 1 second.

STARTING AND DRIVING
344
To allow proper operation of your vehicle’s
ventilation system, keep the inlet grilles in front of the
windshield clear of snow, leaves, or other
obstructions.
 If you smell exhaust fumes in the vehicle, drive with
the windows open and the back door closed. Have
the cause immediately located and corrected.BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, head restraint height
and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
Remember to check that the service reminder indicators
function when turning the key to “ON”, and check the fuel
gauge to see that you have sufficient fuel.

STARTING AND DRIVING
386“ABS” warning light
1U.S.A.2Canada
The light comes on when the ignition key is turned to the “ON”
position. If the anti−lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti −lock brake system, the brake
assist system, the active traction control system and the
vehicle stability control system do/does not operate, but the
brake system still operates conventionally.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti −lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces. If either of the following conditions occurs, this indicates
a malfunction somewhere in the components monitored
by the warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle.

The light does not come on when the ignition key is turned
to the “ON” position, or remains on.
 The light comes on while you are driving.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the “ABS” warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the antilock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Either of the following conditions may occur, but do not
indicate a malfunction:
 The light may stay on for about 60 seconds after the ignition
key is turned to the “ON” position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
light. It is normal if it turns off after a few seconds.

DRIVING TIPS
402
OFFROAD DRIVINGPRECAUTIONS
When driving your vehicle off −road, please observe the
following precautions to ensure your driving enjoyment and to
help prevent the closure of areas to off −road vehicles.
a. Drive your vehicle only in areas where off −road vehicles are
permitted to travel.
b. Respect private property. Get owner’s permission before
entering private property.
c. Do not enter areas that are closed. Honor gates, barriers
and signs that restrict travel.
d. Stay on established roads. When conditions are wet,
driving techniques should be changed or travel delayed to
prevent damage to roads.
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining to driving your
vehicle off −road, consult the following organizations.
 State and Local Parks and Recreation Departments
 State Motor Vehicle Bureau
 Recreational Vehicle Clubs
 U.S. Forest Service and Bureau of Land Management
CAUTION
Always observe the following precautions to 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
offroad. A bad bump could jerk the wheel and injure
your hands. Keep both hands and especially 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.
 In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing
a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is
moving.

DRIVING TIPS
404
WINTER DRIVING TIPS
Make sure your coolant is properly protected against
freezing.
Only use “Toyota Super Long Life Coolant” or similar high
quality ethylene glycol based non−silicate, non −amine,
non− nitrite, and non −borate coolant with long −life hybrid
organic acid technology. (Coolant with long −life hybrid organic
acid technology is a combination of low phosphates and
organic acids.)
See “Checking the engine coolant level” on page 514 for
details of coolant type selection.
For the U.S.A. — “T oyota Super Long Life Coolant” is a mixture
of 50% coolant and 50% deionized water. This coolant
provides protection down to about −35C (− 31F).
For Canada — “Toyota Super Long Life Coolant” is a mixture
of 55% coolant and 45% deionized water. This coolant
provides protection down to about −42C (− 44F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it
must be in top shape to provide enough power for winter
starting. Page 551 tells you how to visually inspect the battery.
Your Lexus dealer and most service stations will be pleased to
check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold
weather.
See page 513 for recommended viscosity. Leaving a heavy
summer oil in your vehicle during winter months may cause
harder starting. If you are not sure about which oil to use, call
your Lexus dealer — they will be pleased to help.
Check the electronic ignition system for loose
connections or obvious damage.
Keep the door locks from freezing.
Squirt lock de− icer or glycerine into the locks to keep them from
freezing.
Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto
parts stores. Follow the manufacturer’s directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute
because it may damage your vehicle’s paint.

DRIVING TIPS
412
Service connector for towing brake controller
Your vehicle is equipped with a service connector for the
towing brake controller as shown. Link the connector to the
towing brake controller via the sub wire harness stored in the
glove box. The detailed explanation of the sub wire harness
circuit is packed together with the sub wire harness. Be sure
to position the towing brake controller where it does not prevent
the driver from operating the pedal. Lexus recommends that
the sub wire harness be stored in the glove box when it is not
in use.
Tires
 Ensure that your vehicle’s tires are properly inflated. Adjust
the tire inflation pressure to the recommended cold tire
inflation pressure indicated below.
Tire inflation pressure: 220 kPa (2.2 kgf/cm
2 or bar, 32 psi)
 The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect to the
total trailer weight.
