Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
Linked mirror function when reversing
When either “L” or “R” of the mirror select switch is selected, the outside
rear view mirrors will automatically angle downwards when the vehicle is
reversing in order to give a better view of the ground. To disable this func-
tion, select neither “L” nor “R”.
If the mirror angle adjustment switch is operated while the linked mirror
function is in operation, the angle and position of the mirrors can be remem-
bered, and the mirrors will operate at the angle adjusted to the last time the
linked mirror function was operated.
However, because the mirrors move based on the angle they are in when the
linked mirror function is not operating, the mirror angle when the linked
mirror function is operating will also be changed if the mirrors are adjusted
while the function is not operating.
Rain clearing mirrors (if equipped)
When water droplets collects on the mirror surface, for example when it
rains, the rain clearing (hydrophilic) effect of the mirrors causes the droplets
to be spread out into a film making the rear view clearer. In the following
cases, the rain clearing effect will be reduced temporarily, but will return
after 1 or 2 days’ exposure to direct sunlight.
After wiping dirt off the mirrors
When the mirrors fog up
After waxing your vehicle in an automatic car wash
After your vehicle has been parked for a long period in underground park-
ing lots etc. where there is no direct sunlight
When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror defoggers.
Turn on the rear window defogger to turn on the outside rear view mirror
defoggers. (P. 430)
Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automati-
cally by the driving position memory. (P. 162)

Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror is set to automatic mode, the out-
side rear view mirrors will activate in conjunction with the anti-glare inside
rear view mirror to reduce reflected light. (P. 172)
Using automatic mode in cold weather
When automatic mode is used in cold weather, the door mirror could freeze
up and automatic stowing and return may not be possible. In this event,
remove any ice and snow from the door mirror, then either operate the mirror
using manual mode or move the mirror by hand.
CAUTION
Important points while driving
Observe the following precautions while driving.
Failure to do so may result in loss of control of the vehicle and cause an
accident, resulting in death or serious injury.
Do not adjust the mirrors while driving.
Do not drive with the mirrors folded.
Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
When a mirror is moving
To avoid personal injury and mirror malfunction, be careful not to get your
hand caught by the moving mirror.
When the mirror defoggers are operating
Do not touch the rear view mirror surfaces, as they can become very hot
and burn you.
NOTICE
If the mirrors become iced up (vehicles with rain-clearing mirror)
In order to retain the rain-clearing properties of the mirror, do not attempt to
scrape the ice off. Instead, remove it by turning on the mirror defoggers or
by applying warm water.

CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When driving the vehicle
During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult
to steer and brake, so you should pull over and stop the vehicle as soon as
it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 7 3 9
Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 214)
Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
When driving on slippery road surfaces
Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid.
After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are
wet and not functioning properly, steering control may be affected.

NOTICE
When driving the vehicle
Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.
Do not use the accelerator pedal or depress the accelerator and brake ped-
als at the same time to hold the vehicle on a hill.
When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to
move or the vehicle may accelerate suddenly if the accelerator pedal is
accidentally depressed.
Avoiding damage to vehicle parts
Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds or vibrations.
The vehicle will lean abnormally.

Driving
GS350/250_EE (OM30C36E)Your vehicle will handle differently when towing a trailer. In order
to avoid accident, death or serious injury, keep the following in
mind when towing:
Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection
between the trailer and lights after driving for a brief period as
well as before starting off.
Practicing driving with a coupled trailer
Get the feel for turning, stopping and reversing with the trailer
coupled by practicing in an area with no or light traffic.
When reversing with a coupled trailer, hold the section of the
steering wheel nearest to you and rotate clockwise to turn the
trailer left or counterclockwise to turn it right. Always rotate a
little at a time to prevent steering error. Have someone guide
you when reversing to lessen the risk of an accident.
NOTICE
When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that
area.
When steel and aluminum come into contact, there is a reaction similar to
corrosion, which will weaken the section concerned and may result in dam-
age. Apply a rust inhibitor to parts that will come in contact when attaching
a steel bracket.

Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle run-
ning ahead of you should be equivalent to or greater than the
combined length of your vehicle and trailer. Avoid sudden brak-
ing that may cause skidding. Otherwise, the vehicle may spin out
of control. This is especially true when driving on wet or slippery
road surfaces.
Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer col-
liding with your vehicle. Decelerate well in advance when
approaching turns and take them slowly and carefully to avoid
sudden braking.
Important points regarding turning
The wheels of the trailer will travel closer to the inside of the
curve than the wheels of the vehicle. To make allowance for this,
take the turns wider than you would normally do.
Important points regarding stability
Vehicle movement resulting from uneven road surfaces and
strong crosswinds will affect handling. The vehicle may also be
rocked by passing buses or large trucks. Frequently check behind
when moving alongside such vehicles. As soon as such vehicle
movement occurs, immediately start to decelerate smoothly by
slowly applying the brakes. Always steer the vehicle straight
ahead while braking.
Passing other vehicles
Consider the total combined length of your vehicle and trailer
and ensure that the vehicle-to-vehicle distance is sufficient
before executing lane changes.
Transmission information
To maintain engine braking efficiency, when using engine brak-
ing, when driving on a long steep downgrade, do not use the
