ENGINE COOLANT
TEMPERATURE GAUGE
13L002±2

Normal range
The gauge indicates the engine coolant temperature
when the ignition switch is on. The engine operating
temperature will vary with changes in weather and
engine load.
If the needle points to the red zone or higher, stop your
vehicle and allow the engine to cool.
Your vehicle may overheat during severe operating
conditions, such as:
 Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
 Idling for a long period with the air conditioning on in stop±and±go traffic.
 Towing a trailer.
NOTICE
Do not remove the thermostat in the engine
cooling system as this may cause the engine to
overheat. The thermostat is designed to control the flow of coolant to keep thetemperature of the engine within the specifiedoperating range.
Do not continue driving with an overheatedengine. See ºIf your vehicle overheatsº onpage 347.

STARTING AND DRIVING

(f) Good driving practice
If the transmission repeatedly upshifts and
downshifts between the fourth and overdrive gears
when climbing a gentle slope, shift the selector lever
to the º4º position. Be sure to shift the selector lever
to the ºDº position after climbing the slope.
 When towing a trailer, in order to maintain efficient
engine braking and electrical charging performance,
do not use overdrive. The selector lever must be in
the º4º position.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Do not hold the vehicle on an upgrade with the accelerator pedal. This can cause thetransmission to overheat. Always use the brakepedal or parking brake.
(g) Rocking your vehicle if stuck

DRIVING TIPS

BREAK±IN PERIOD
Drive gently and avoid high speeds.
You need not follow a break±in schedule with your new
Lexus. But following a few simple tips for the first 1600
km (1000 miles) can add to the future economy and long
life of your vehicle:
Do not drive over 88 km/h (55 mph).
 Avoid overrevving. Maintain engine speed between
2000 and 4000 rpm.
 Avoid full±throttle starts.
 Try to avoid hard stops during the first 300 km (200
miles).
 Do not drive for a long time at any single speed, either
fast or slow.
 Do not tow a trailer during the first 800 km (500 miles).
OPERATION IN FOREIGN
COUNTRIES
If you plan to drive your Lexus in another country ...
First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel
(unleaded and minimum octane rating).
TIPS FOR DRIVING IN VARIOUS CONDITIONS
Always slow down in gusty crosswinds. This will
allow you much better control.
 Drive slowly onto curbs and, if possible, at a right
angle. Avoid driving onto high, sharp±edged objects
and other road hazards. Failure to do so can lead to
severe tire damage resulting in tire bursts.
 When parking on a hill, turn the front wheels until they
touch the curb so that the vehicle will not roll. Apply
the parking brake, and place the transmission in ºPº.
If necessary, block the wheels.
 Washing your vehicle or driving through deep water
may get the brakes wet. To see whether they are wet,
check that there is no traffic near you and then press
the pedal lightly. If you do not feel a normal braking
force, the brakes are probably wet. To dry them, drive
the vehicle cautiously while lightly pressing the brake
pedal with the parking brake applied. If they still do
not work safely, pull to the side of the road and call a
Lexus dealer for assistance.
CAUTION
 Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.

DRIVING TIPS
326Depending on where you are driving, we
recommend
you carry some emergency equipment.
Some of the things you might put in the vehicle are tire
chains, w indow scraper, bag of sand or salt, flares, small
shovel, jumper cables, etc.
TRAILER TOWING
Your vehicle is designed primarily as a
passenger±carrying vehicle. Towing a trailer will have
an adverse effect on handling, performance, braking,
durability and driving economy (fuel consumption, etc.).
Your safety and satisfaction depend on the proper use
of correct equipment and cautious driving habits. For
your safety and the safety of others, you must not
overload your vehicle or trailer. Lexus warranties do not
apply to damage or malfunction caused by towing a
trailer for commercial purposes. Ask your local Lexus
dealer for further details before towing.
NOTICE
When towing a trailer, be sure to consult your Lexus dealer for further information on additional
requirements such as a towing kit, etc.

DRIVING TIPS
327
Weight limits
Before towing, make sure the total trailer weight,
gross vehicle weight, gross axle weight and trailer
tongue load are all within the limits.
The total trailer weight and tongue load can be
measured with platform scales found at a highway
weighing station, building supply company, trucking
company, junk yard, etc.
32L001

Certification label
CAUTION
The total trailer weight (trailer weight plus its cargo
load) must not exceed 907 kg (2000 lb.). Exceeding
this weight is dangerous.

DRIVING TIPS
328
Trailer hitch assemblies have different weight
capacities established by the hitch manufacturer.
Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine
the maximum weight rating of the particular hitch
assembly and never exceed the maximum weight
rating specified for the trailer hitch. Exceeding the
maximum weight rating set by the trailer hitch
manufacturer can cause an accident resulting in
serious personal injuries.
 The gross vehicle weight must not exceed the Gross
Vehicle Weight Rating (GVWR) indicated on the
Certification Label. The gross vehicle weight is the
sum weight of the unloaded vehicle, driver,
passengers, luggage, hitch and trailer tongue load.
it also includes the weight of any special equipment
installed on your vehicle.
 The load on either the front or rear axle resulting from
distribution of the gross vehicle weight on both axles
must not exceed the Gross Axle Weight Rating
(GAWR) listed on the Certification Label.

Tongue load
Total trailer weight x 100 = 9 to 11%
DRIVING TIPS
329
32L002

Total trailer weight
Tongue load

The trailer cargo load should be distributed so
that the tongue load is 9 to 11 % of the total
trailer weight, not exceeding the maximum of
90 kg (200 lb.).
 Never load the trailer with more weight in the
back than in the front. About 60 % of the trailer
load should be in the front half of the trailer and
the remaining 40 % in the rear.
