2003 SUBARU IMPREZA WRX traction control

Starting and operating
7-18
3 (Third)
This position is for using engine braking when going down a hill or for climbing a grade.The transmission automatically shifts into a suitable
gear from 1st to 3rd according to the vehicle speed
and the acceleration you require.
When more acceleration is required in this position,
press the accelerator pedal fully to the floor and hold that position. The transmission will automatical-
ly downshift to 2nd or 1st gear. When you release
the pedal, the transmission will return to the originalgear position.
2 (Second)
This position is for using engine braking when goingdown a hill or for climbing a steep grade.In this position, the transmission holds in the 2nd
gear.
Use this position when starting off from a standstill
on slippery road surfaces such as mud or snow. It
will ensure greater traction.
1 (First)
This position is for driving up or down very steep
grades, or driving through mud or sand, or on slip-
pery surfaces. In this position, the transmission
holds in the 1st gear.
Maximum speeds
The following tables show the maximum speeds that
are possible with each different gear. The tachome-ter’ s needle will enter the red area if these speeds
are exceeded.
When shifting down a gear, it is important to confirm
that the current vehicle speed is not in excess of the
Maximum Allowable Speed of the gear which is
about to be selected.Exceeding the Maximum Allowable Speeds will
result in over-revving of the engine. In addition a
powerful engine brake will engage and control of the vehicle may be lost. mph (km/h)

gerous and lead to loss of vehicle control. You must install four winter tires that are of
the same size, construction, brand, and loadrange. Mixing other sizes or constructions
may result in severe mechanical damage to
the drive train of your vehicle and may affect
ride, handling, braking and speedometer/ odometer calibration. It also may be danger-ous and lead to loss of vehicle control. Do not use a combination of radial, belted
bias or bias tires since it may cause danger-ous handling characteristics and lead to an accident.
Your vehicle is equipped with “all season tires ” as
original equipment, which are designed to provide
an adequate measure of traction, handling and
braking performance in year-round driving. In winter,
it may be possible to enhance performance through
use of tires designed specifically for winter drivingconditions.
The optional 17-inch tires for the WRX are summer
tires. Compared with winter and all-season tires,
summer tires give significantly less grip on snowy
and icy road surfaces. Therefore, use of winter tires
is strongly recommended when driving with such
road conditions. When you choose to install winter tires on your ve-
hicle, be sure to use the correct tire size and type.
You must install four winter tires that are of the samesize, construction, brand and load range and you
should never mix radial, belted bias or bias tires
since this may result in dangerous handling charac-
teristics. When you choose a tire, make sure that
there is enough clearance between the tire and ve-
hicle body.
Remember to drive with care at all times regardless
of the type of tires on your vehicle.
Tire chains
Driving on snowy grades or icy roads may require
the use of tire chains, in which case put the chains
on the front wheels only. Use only SAE class S type
chains that are of the correct size for your tires so asnot to damage the vehicle body or suspension.
When driving with tire chains, drive at speeds below 19 mph (30 km/h).
When a temporary spare tire is on a front wheel, re-
place the temporary spare tire with the rear tire onthe same side of the vehicle, and then fit chains on
the front tires.
Always use the utmost care when driving with tire

WARNING
The traction grade assigned to this tire is based on straight-ahead braking tractiontests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac- teristics.
Temperature A, B, C
The temperature grades are A (the highest), B, and
C, representing the tire ’s resistance to the genera-
tion of heat and its ability to dissipate heat when
tested under controlled conditions on a specified in-
door laboratory test wheel. Sustained high tempera-
ture can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corresponds
to a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle
Safety Standards No. 109. Grades B and A repre-
sent higher levels of performance on the laboratory
test wheel than the minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, underinfla-tion, or excessive loading, either separately or in combination, can cause heat buildup and
possible tire failure.
